The quadrilateral is a parallelogram.find the value of x and y..

Answer: B: (y + z = 6) × -5

Step-by-step explanation:

if you multiply 'y' by -5 it turns into -5y. Therefore when you add -5y and 5y together, you get 0y which is what you want when eliminating the y-term.

Answer:

134 :)

Step-by-step explanation:

The equation representing visual models is z+1/5=3/5.

Since it is given in the question that the hanger image represents a balanced equation therefore equating LHS with RHS it can be written as follows.

LHS = 1/5 + z

RHS = 3/5+ z

Equating both the equations it can be written as

LHS = RHS

1/5+z=3/5

or z=3/5-1/5

Therefore, z=2/5

Hence, for  z=2/5 the hanger will represent a balanced equation.

A major disadvantage of electron microscopes compared to light microscopes is that they cannot be used to view live specimens. Therefore, option B is the correct answer.

A major disadvantage of electron microscopes compared to light microscopes is that they cannot be used to view live specimens. This is because the electron microscope requires a vacuum environment to function properly, which would kill any live specimen. Additionally, electron microscopes can only see surface details and do not have a very high power of resolution. Lastly, electron microscopes can only be used by doctors or trained technicians, so they are not as widely available as light microscopes.

Therefore, option B is the correct answer.

The radius of the cone is 3 times the radius of the cylinder, given that they have equal volumes and radii of equal length.

The height of the cylinder is also 24 centimeters since the radii are equal.

To find the volume of the cylinder, use the formula V = πr^2h, where r is the radius and h is the height.

To find the volume of the cone, use the formula V = (1/3)πr^2h, where r is the radius and h is the height.

Since the volumes are equal, you can set up the equation (1/3)πr^2(24) = πr^2(24) and solve for r.

Simplifying the equation, you get (1/3) = 1.

This means that the radius of the cone is 3 times the radius of the cylinder.

Therefore, the radius of the cone is 3 times the radius of the cylinder, given that they have equal volumes and radii of equal length.

Answer:

When reflecting a point or line segment across the x-axis, the y-coordinate changes sign while the x-coordinate remains the same. In this case, we are given the points A (2,5) and B (-3,6) and asked to find their reflections in the x-axis, represented by the points A’ and B’.To reflect point A across the x-axis, we simply change the sign of the y-coordinate while keeping the x-coordinate the same. So, if A is (2,5), its reflection A’ is (2,-5). We can follow the same procedure for point B. If B is (-3,6), its reflection B’ is (-3,-6).From this calculation, we see that answer choice A is the correct one. Therefore, A’(2,-5) and B’(-3,6) represent the points that are the reflections of A and B, respectively, across the x-axis.The reflection of a point across the x-axis can also be visualized as the point being mirrored across the x-axis as if it were a horizontal mirror. In this case, point A is reflected to the point A’ which is the same distance above the x-axis as A is below the x-axis. Similarly, point B is reflected to point B’ which is the same distance below the x-axis as B is above the x-axis.It’s also worth noting that reflecting a point or line segment across the x-axis is an example of a transformation in coordinate geometry. Translations, reflections, rotations, and dilations are all examples of transformations that can be used to manipulate geometric figures on the coordinate plane.Overall, reflecting a point or line segment across the x-axis is a relatively simple calculation that involves negating the y-coordinate. In the context of coordinate geometry, it’s important to understand the basic transformations like these and how they can be used to manipulate shapes and figures on the coordinate plane.

Step-by-step explanation:

(1) Every vector space V with dimension n and a generating set S contains a subset that forms a basis for V.

(2) The generating set S for a vector space V must contain at least n vectors.

(1) To prove that there is a subset of S that forms a basis for V, we can use the concept of linear independence. Since S generates V, we can start with S as a potential basis for V. If S is linearly independent, then it already forms a basis for V.

Otherwise, we can remove vectors from S that are linearly dependent on the remaining vectors until we obtain a linearly independent subset. This subset will still generate V and will form a basis for V.

(2) To prove that S must contain at least n vectors, we use the fact that the dimension of a vector space is the minimum number of vectors required to generate it. Since V has dimension n, it implies that at least n vectors are needed to generate V.

Therefore, the generating set S for V must contain at least n vectors.

These proofs highlight the fundamental properties of vector spaces and their generating sets, emphasizing the existence of bases and the relationship between the dimension of the vector space and the number of vectors needed in its generating set.

Answer:

\(17\sqrt{2}\) ft

Step-by-step explanation:

take angle b as reference angle

using sin rule

sin 45 = opposite / hypotenuse

\(\frac{1}{\sqrt{2} }\) = 17 / BC

BC =17 / \(\frac{1}{\sqrt{2} }\)

BC = 17 * \(\sqrt{2}\)

BC =  \(17\sqrt{2}\) ft

Answer:

BC = 17\(\sqrt{2}\) ft

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = \(\frac{1}{\sqrt{2} }\) , then

sin45° = \(\frac{opposite}{hypotenuse}\) = \(\frac{AC}{BC}\) = \(\frac{17}{BC}\) = \(\frac{1}{\sqrt{2} }\) ( cross- multiply )

The cost described in the scenario is an example of a mixed cost.

A mixed cost consists of both fixed and variable components. In this case, the $10 per month base charge represents the fixed component of the cost. This charge remains constant regardless of the amount of electricity consumed. It covers the basic service and is not influenced by usage levels.

On the other hand, the additional charge of $0.08 per kilowatt-hour (kWh) of electricity used represents the variable component. This charge varies directly with the amount of electricity consumed. As more electricity is used, the variable cost increases proportionally.

By combining the fixed base charge and the variable charge per kWh, we get a mixed cost structure. The fixed component ensures a minimum cost for the service, while the variable component adds to the total cost based on actual usage. This combination of fixed and variable elements makes the cost a mixed cost.

Therefore, The probability that the device will work is 0.634 or 63.4%.

This problem can be solved using the complement rule. The complement of the device working is all the parts failing. Therefore, the probability of the device not working is (1 - 0.216)^7 = 0.366. To find the probability of the device working, we subtract this from 1:
1 - 0.366 = 0.634.
To find the probability that the device will work, we'll use the complementary probability. This means we'll first find the probability that all parts fail and then subtract it from 1. Let's denote the probability of a part failing as q, which is equal to 1 - p.
Step 1: Calculate q.
q = 1 - p = 1 - 0.216 = 0.784
Step 2: Calculate the probability of all parts failing.
P(all parts fail) = q^7 = 0.784^7 ≈ 0.1278
Step 3: Calculate the probability that the device will work.
P(device works) = 1 - P(all parts fail) = 1 - 0.1278 ≈ 0.8722
In conclusion, the probability that the device will work is approximately 0.8722.

Step-by-step explanation:

Put a point at (5,3) then go up 3 and right 5 for the second point then do it again for the third point.

The following are the zeros for the function h (x) = x2 + 3x - 8: - x= -4 and x=2.

Given a collection of inputs X (domain) and a set of potential outputs Y (codomain), a function is more technically defined as a set of ordered pairings (x,y) where xX and yY with the caveat that there can only be one ordered pair with the same value of x. The function notation f:XY can be used to express that f is a function from X to Y.

The function's zero is a value of x that makes it equal to zero. In other words, the equation f(x) = 0 leads to a zero.

By putting h(x) equal to zero and figuring out x, we may determine the zeroes for the function h(x) = x2 + 3x - 8.

h(x) = x² + 3x - 8 = 0

We may factor the left side of the equation to find x:

x² + 3x - 8 = (x-2)(x+4) = 0

We set each factor to zero and solve for x to discover the zeroes:

x-2 = 0 or x+4 = 0

x = 2 or x = -4

Consequently, the function's zeros are x = 2 and x = -4.

So, A is the right response. x = -4 and x = 2

Answer:

Part A

The perimeter of the of the shaded region is (3·π + 6 + 6·(√2)) cm

Part B

\(The \ area \ of \ the \ figure = 4\dfrac{1}{2} \cdot \pi + 18 \ cm^2\)

Step-by-step explanation:

Part A

The perimeter of the the shaded region is given as follows;

The perimeter of the the shaded region = The perimeter of the semicircle + The perimeter of the right triangle with legs 6 cm each - The length of the dotted line

The perimeter of the semicircle = π × r

We note that the diameter of the semicircle, D =  \(\overline{AB}\) = 6 cm

The radius of the semicircle, r = D/2 = 6 cm/2 = 3 cm

∴ The perimeter of the semicircle = π × 3 cm = 3·π cm

The perimeter of the right triangle with legs 6 cm each = The length of the 2 6 cm legs + The length of the hypotenuse side

By Pythagoras' theorem, the length of the hypotenuse side = √(6² + 6²) = 6·(√2) cm

∴ The perimeter of the right triangle = 6 cm + 6 cm + 6·(√2) cm = (12 + 6·(√2)) cm

The length of the dotted line = The the length of side \(\overline{AB}\) of the square from which the right triangle ABC is based

∴ The length of the dotted line = The length of \(\overline{AB}\) = 6 cm

∴ The perimeter of the figure = 3·π cm + (12 + 6·(√2)) cm - 6 cm = (3·π + 6 + 6·(√2)) cm

The perimeter of the of the shaded region = (3·π + 6 + 6·(√2)) cm

Part B

Given that the figure is made up of portion of a square and a semicircle, we have;

BC ≅ AB = 6 cm

The area of semicircle BC with radius BC/2 = 3 is 1/2×π×r² = 1/2×π×3² = 4.5·π cm²

Triangle ABC = 1/2 × Area of square  from which ABC is cut

The area of triangle ABC = 1/2×Base ×Height = 1/2×AB×BC = 1/2×6×6 = 18 cm²

The area of the figure = The area of semicircle BC + The area of triangle ABC

The area of the figure = 4.5·π cm² + 18 cm² = \(\dfrac{9 \cdot \pi +36}{2} \ cm^2\)

The estimate of the impact that a successful preventive program might have can be derived from

attributable risk.

In epidemiology, attributable risk or excess risk is a phrase equivalent with risk difference, which has also been used to express the attributable proportion among the exposed and the population.

Attributed risk assists in determining how much of an outcome is attributable to a certain risk factor (i.e., an estimate of the excess risk) in a population exposed to that factor.

The rate (percentage) of a health result (illness or death) in exposed persons that can be linked to the exposure is known as the attributable risk (AR). Attribitable risk measures how much more common a result is in absolute terms among the exposed than the non-exposed.

Answer:

9 songs will be on the final CD

Step-by-step explanation:

The band writes and records 20% more songs than they expected to put on CD (they expected to put 15 on CD) , hence 3 more songs since 20% of 15 is 3 (= 15 × 0.20). A total of 18 songs is recorded.

During editing, 50% of the songs are removed, that is 9 (= 18 × 0.50).

Therefore, only 9 songs are left on CD (= 18 - 9)

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

The number of songs in the final CD is 9.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

The number of total songs.

= 15 + (20% of 15)

= 15 + (1/5 x 15)

= 15 + 3

= 18

Now,

The number of removed songs.

= 50% of 18

= 1/2 x 18

= 9

The number of songs on the final CD.

= 18 - 9

= 9

Thus,

The number of songs in the final CD is 9.
