Step-by-step explanation:

a) 4

b) 4

c) 4

d) DNE

why is that ? as there is a hollow dot in the curve exactly at x = -3, there is no defined functional value for x = -3.

but it is only this one specific dot that is excluded. so, the lim calculation can still use it for a) - c). although it changes direction there, it is still the same coming from left or from right. and therefore it is the same limit overall.

e) 1

f) -1

g) DNE

h) 1

at x = 0 the function has a jumping discontinuity. therefore, the limits are different when coming from left or from right. and because of this difference, the general limit does not exist. the functional value at x = 0 is part of the curve coming from the left.

i) 2

j) DNE

similar to a) - d). the point (but only the single point) at x = 2 is excluded from the function and has no assigned functional value. nevertheless, it can still be used for the limit calculation.

k) it is not very well to see in the picture. when coming from the right, it appears to be 3.

but it might be possible that it goes further down to 2.

l) similar to k) it is not good to see in the picture. when coming from the left, is the wild "swinging" ending at 2 ? or going back up to 3 to meet the functional curve of k) ?

I would suspect it is 3, but it could be 2.

you need to decide k) and l) when you look at your original, because the picture is too fuzzy to be sure.

Step-by-step explanation:

5 laptops costs 163,750(5x32750). Total costs of 229,600-laptops 163,750=costs of desktop 65850.

Answer:

198 children, 152 adults

Step-by-step explanation:

So this problem can be broken down into an equation system with 2 equations.
Let's use variable x for number of children and y for number of adults.
You are given, that 350 people in total used the pool on this certain day.
This gives you the first equation:
x + y = 350

Then you are given the totaled admission of 627.50. When each child paid 1.25 and each adult paid 2.50, this gives you the second equation:
1.25*x + 2.50*y = 627.50

To get the value of both x and y, first solve one equation for x;
x + y = 350
x = 350 - y

and then put this value into the other equation:
1.25*x + 2.5*y = 627.5
1.25*(350-y) + 2.5*y = 627.5

and then you solve for y:
437.5 -1.25*y + 2.5*y = 627.5
437.5 + 1.25*y = 627.5
1.25*y = 190
y = 152

so 152 adults used the pool this day.
Then you put this value for y into any of your equations and solve for x:
x + y = 350
x + 152 = 350
x = 350 - 152
x = 198

so 198 children used the pool this day.

The correct answer is Graph 1: y = cos(x/4)Graph 2: y = cos(x/2)

Based on the given descriptions of the graphs and the patterns they follow, the correct pairs are:

Graph 1: y = cos(x/4) ⟶ This graph has a period of 8 units and matches the pattern described.Graph 2: y = cos(x/2) ⟶ This graph has a period of 4 units and matches the pattern described.

Graph 3: y = cos(x) ⟶ This graph has a period of 2π (or approximately 6.28 units) and matches the pattern described.

Graph 4: (Not used)

Graph 5: (Not used)

Answer:

Step-by-step explanation:

Unit stands for one so

120 meters in 12 seconds in 10 meters a sec

Resulting box has the greatest volume for the values  (25 ± 5√7)/6 .

This is a problem that can be solved using derivatives , maxima & minima and common logic.

Hence , going by logic :

Creating a flap of 'a' inches in width, the base of the box will be

 (10 - 2a) by (15 - 2a)

and the depth of the box will be the width of the fold-up flap: a.

Then the volume of the box is

 v = \(a(10 -2a)(15 -2a) = 150a -50a^2 +4a^3\)

Using the derivative of the volume will be zero at the maximum volume.

 0 = \(dv/da = 150 -100a +12a^2\)

This has roots at

 a = (100 ±√(100² - 4(12)(150)))/(2·12)

 a = (100 ± √2800)/24 = (25 ± 5√7)/6

Only the smaller of these solutions gives a maximum volume.

You should cut (5/6)(5-√7) ≈ 1.962 inches to obtain the greatest volume.

Similarly , replacing the values of 10 by A and 15 by B , a generalized solution can be formed .

Step-by-step explanation:

I guess, the silent request here is that there will be no wire left after the 10th square.

and I guess, the following square does not reuse one side of the previous square. all squares are "standalone".

T stands for area ? well, ok.

when the side length doubles, the area quadruples (the area is side×side, and factor 2 × factor 2 = factor 4). but the perimeter still only doubles.

T1 = x × x = x²

T2 = x×2 × x×2 = x² × 4 = T1 × 4

Tn = Tn-1 × 4 = T1 × 4^(n-1) = x² × 4^(n-1)

so, Tn/Tn-1 = 4

but the geometric series for the perimeter is

p1 = 4x

pn = pn-1 × 2 = x × 2^(n+1)

and pn/pn-1 = 2

the sum of a finite geometric series with n elements is

s = p1 × (1 - r^(n))/(1 - r)

r is the common factor. in our case it is 2.

and we have 10 elements.

so, we know

8184 = 4x × (1 - 2^(10))/(1 ‐ 2) = 4x × (1-2¹⁰)/-1 =

= 4x × -1023 / - 1 = 4x × 1023

2046 = x × 1023

x = 2046/1023 = 2 cm

so, now finally for iii)

T10 (the last, biggest square) = x² × 4⁹ = 4×4⁹ = 4¹⁰ =

Luis will be required to make Payments for a period of 21 months. Therefore, the correct answer is: A. 21

The number of payments Luis will be required to make, we need to calculate the total loan term, taking into account the initial period with no payments.

The loan term is 3 years, which is equivalent to 36 months. However, the loan offers no payments for the first 15 months. Therefore, we subtract the 15-month grace period from the total loan term:

36 months - 15 months = 21 months

Luis will be required to make payments for a period of 21 months.

Answer:

The 95% confidence  interval is \((150\pm 8.8)\).

Step-by-step explanation:

The information provided is:

\(\bar x=150\\\sigma = 20\\n=20\)

The critical value for 95% confidence level is:

\(z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.96\)

Compute the margin of error as follows:

\(MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}\)

          \(=1.96\times\frac{20}{\sqrt{20}}\\\\=1.96\times 4.47214\\\\=8.7653944\\\\\approx 8.8\)

Then the 95% confidence  interval is:

\(CI=\bar x\pm MOE\)

     \(=150\pm 8.8\)

Thus, the 95% confidence  interval is \((150\pm 8.8)\).

y = 3x              Yes         No

y = x/5              Yes         No

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

y = 2x³ + 1

For x = 1, 2, 3,

y = 2 + 1 = 3

y = 2 x 2³ + 1 = 2 x 8 + 1 = 17

y = 2 x 3³ + 1 = 2 x 27 + 1 = 54 + 1 = 55

The rate of change.

Between 3 and 17 = 17 - 3 = 14

Between 17 and 55= 55 - 17 = 38

This means the equation is not linear.

y = 3x

For x = 1, 2, 3,

y = 3 x 1 = 3

y = 3 x 2 = 6

y = 3 x 3 = 9

The rate of change.

Between 3 and 6 = 6 - 3 = 3

Between 6 and 9 = 9 - 6 = 3

This means the equation is linear.

y = x/5

For x = 1, 2, 3,

y = 1/5

y = 2/5

y = 3/5

The rate of change.

Between 1/5 and 2/5 = 2/5 - 1/5 = 1/5

Between 2/5 and 3/5= 3/5 - 2/5 = 1/5

This means the equation is linear.

Thus,

y = 2x³ + 1 is a linear equation.

y = 3x is not a linear equation.

y = x/5 is a linear equation.

The statement about the function is: "The function is decreasing for all real values of x where x < -4." D.

The given information tells us that the graph represents a downward-opening parabola.

The vertex of the parabola is located at (-4, 4) indicates that this point is the highest point on the graph.

As we move to the left of the vertex, the function values decrease, indicating a decreasing trend.

Moreover, the graph passes through the point (-6, 0), which lies to the left of the vertex.

This confirms that the function is decreasing for all real values of x less than -4, including x < -6.

On the other hand, the graph also passes through the point (-2, 0), which lies to the right of the vertex.

This does not impact the conclusion that the function is decreasing for x < -4, as the graph's behavior to the right of the vertex is not relevant to this particular statement.

Based on the given information and the properties of the downward-opening parabola, we can conclude that the function is decreasing for all real values of x where x < -4.

Answer:

-5/4

Step-by-step explanation:

Let \((x_1,y_1)=(-4,4)\) and \((x_2,y_2)=(0,-1)\). The slope of the line would be:

\(\displaystyle \frac{y_2-y_1}{x_2-x_1}=\frac{-1-4}{0-(-4)}=\frac{-5}{4}=-\frac{5}{4}\)

Answer: -5/4

Step-by-step explanation:

To find the slope between two points, you can use the formula:

Slope = (y2 - y1)/(x2 - x1)

Using the points (0, -1) and (-4, 4), we can substitute the coordinates into the formula:

slope = (4 - (-1))/(-4 - 0)

slope = (4 + 1)/(-4)

slope = 5/-4

Therefore, the slope between the two points is -5/4.

If a high school student decides to apply four of six famous colleges, then the four colleges can be selected in as many as 15 different combinations.

As per question statement, a high school student decides to apply four of six famous colleges.

We are required to calculate the number of combinations in which the four colleges can be selected.

To solve this question, we need to know the formula of Combination which goes as \((nCr)=\frac{n!}{r!(n-r)!}\)

, i.e., we are to select a set or "r" from a set of "n".

Here, we have to select a combination of 4 from a set of 6.

Therefore applying (nCr) formula with (n = 6) and (r = 4), we get,

\((6C4)=\frac{6!}{4!(6-4)!} =\frac{6!}{4!2!}=\frac{4!*5*6}{4!*2}=\frac{5*6}{2}=(5*3)=15\).

Answer:

x < -3 or x > 2

Step-by-step explanation:

x² + x - 6 > 0

Convert the inequality to an equation.

x² + x - 6 = 0

Factor using the AC method and get:

(x - 2) (x + 3) = 0

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

x - 2 = 0

x = 2

x + 3 = 0

x = -3

So, the solution is x < -3 or x > 2
