how many terms are in this expression 8+(10-7)​

Let's analyze Jenny's bowling expenses, considering the cost of renting bowling shoes and the price per game. By determining the total amount she paid and using the given information, we can calculate the number of games Jenny bowled.

Step-by-step explanation:

Let's set the number of games Jenny bowled as 'x'.

Jenny paid $2.75 for renting the bowling shoes and $4.25 for each game. The total amount she paid is $24.

The total amount Jenny paid for the games can be represented as: $4.25 * x.

So, the equation can be set up as:

$2.75 + $4.25 * x = $24.

To find the value of 'x', we need to solve the equation.

Subtracting $2.75 from both sides:

$4.25 * x = $24 - $2.75.

$4.25 * x = $21.25.

Dividing both sides by $4.25:

x = $21.25 / $4.25.

x = 5.

Answer: Therefore, Jenny bowled a total of 5 games.

Answer:

The answer would be 12.

Step-by-step explanation:

I got 12 using the information we were given. Seeing as 8km is represented by 2cm, 1 cm would be 4km, right? (8 divided by 2 is 4.) So using that, we just need to multiply 4 by 3 to find what the 3km would be on the map.

Answer:

no solution

Step-by-step explanation:

use the second equation because y is already by itself

-4 x = y + 8

y = -4x - 8

substitute:

12x + 3(-4x - 8) = 22

distribute the 3:

12x -12x - 24 = 22

0 - 24 = 22

-24 ≠ 22

1) Let's start by expanding the table so that we find all the information to the Linear Regression function

2) Now we can work on the equation

So to find the slope let's plug into that:

And the linear coefficient:

3) Then the line that best fits this data is described by, rounding to two decimal places:

Answer:

the answer is 4

Step-by-step explanation:

Using the trapezoidal rule with 5 ordinates, we approximate the integral [sin(x²+1) dx] over the interval [0,1] to be 0.5047 to 4 decimal places.

To approximate the integral [sin(x²+1) dx] using the trapezoidal rule with 5 ordinates, we can use the following formula:

∫[a,b]f(x)dx ≈ [(b-a)/2n][f(a) + 2f(a+h) + 2f(a+2h) + 2f(a+3h) + 2f(a+4h) + f(b)]

where n is the number of ordinates (in this case, n = 5), h = (b-a)/n is the interval width, and f(x) = sin(x²+1).

First, we need to find the interval [a,b] over which we want to integrate. Since no interval is given in the problem statement, we'll assume that we want to integrate over the interval [0,1].

Therefore, a = 0 and b = 1.

Next, we need to find h:

h = (b-a)/n = (1-0)/5 = 0.2

Now, we can apply the trapezoidal rule formula:

∫[0,1]sin(x²+1)dx ≈ [(1-0)/(2*5)][sin(0²+1) + 2sin(0.2²+1) + 2sin(0.4²+1) +             2sin(0.6²+1) + 2sin(0.8²+1) + sin(1²+1)]

≈ (1/10)[sin(1) + 2sin(0.05²+1) + 2sin(0.15²+1) + 2sin(0.35²+1) + 2sin(0.65²+1) + sin(2)]

≈ (1/10)[0.8415 + 2sin(1.0025) + 2sin(1.0225) + 2sin(1.1225) + 2sin(1.4225) + 1.5794]

≈ 0.5047

Therefore, using the trapezoidal rule with 5 ordinates, we approximate the integral [sin(x²+1) dx] over the interval [0,1] to be 0.5047 to 4 decimal places.

Answer:

r=14 in

Step-by-step explanation:

The volume of a cylinder is given by:

\(v = \pi \times {r}^{2} \times h\)

So,

\(r = \sqrt{ \frac{v}{\pi \times h} } = \sqrt{ \frac{196 \times \pi}{\pi \times 1} } = \sqrt{196} = 14\)

Step-by-step explanation:

solution given.:

radius[r] =r

height[h]=1in

volume[V] of cylinder=196πin³

we have

volume[V] of cylinder=πr²h

196π=πr×1

r²=\( \frac{196π}{π}\)

r=\( \sqrt{196} \)

r=14in

so radius is 14in

a) The distance from point P to the pole  is: 6.2 m

b) The height of the Pole is: 6.2 m

The triangle attached shows us the triangle formed as a result of the given word problem about angle of elevation and distance and height.

Now, we are given that:

The angle of elevation of the top of the pole =  45°

Angle of elevation of the top of the pole = 58°.

|PQ|= 10m

a) PR is distance from point P to the pole and using trigonometric ratios, gives us:

PR/sin 58 = 10/sin(180 - 58 - 45)

PR/sin 58 = 10/sin 77

PR = (10 * sin 58)/sin 77

PR = 8.7 m

b) P O can be calculated with trigonometric ratios as:

P O = PR * cos 45

P O = 8.7 * 0.7071

P O = 6.2 m

Now, the two sides of the isosceles triangle formed are equal and as such:

R O = P O

Thus, height of pole R O = 6.2 m

The value of tan 2π/3 without calculator is -√3.

The value of tan 2π/3 without calculator is calculated by applying trig identities as follows;

the value of π = 180 degrees

So we can replace the value of π in the function with 180 degrees as follows;

tan ( 2π / 3) = tan (2 x 180 / 3)

tan (2 x 180 / 3) = tan (2 x 60)

tan (2 x 60) = tan (120)

tan (120) if found in the second quadrant, and the value will be negative since only sine is positive in the second quadrant.

tan (120) = - tan (180 - 120)

= - tan (60)

= -√3

Step-by-step explanation:

The perimeter of the polygon, with the specified coordinate points , found using Pythagorean Theorem  iis  approximately 16 units

The Pythagorean Theorem indicates that the square of the distance between points on the coordinate plans is the sum of the square of the horizontal and vertical distances between the  point.

The coordinates of the vertices of the polygon are;

(-3, 1), (-3, 3), (-1, 5), (2, 4), and (2, 1)

The length of the sides are therefore;

3 - 1 = 2,

√((-1 - (-3))² + (5 - 3)²) = 2·√2

√((2 - (-1))² + (4 - 5)²) = √(10)

4 - 1 = 3

2 - (-3) = 5

The perimeter is therefore;

2 + 2·√2 +  √(10) + 3 + 5  ≈ 16

Explanation:

Segment AW bisects angle CAD.

This leads to the smaller pieces (angles CAW and DAW) to be equal to one another. Both are 20 degrees each. That totals to 20+20 = 40 degrees.

Therefore, angle CAD = 40 degrees.

The supplement of this is angle DAX

(angle CAD) + (angle DAX) = 180

angle DAX = 180 - (angle CAD)

angle DAX = 180 - 40

angle DAX = 140 degrees

B. a reflection across the x-axis, and then a dilation by a scale factor of 1.5

First, we have that the orientation of the figure, hence it was reflected.

The figure was reflected from the second quadrant to the third quadrant, hence the figure was reflected over the x-axis.

The base segment changes from a length of 2 units to a 3 units, hence the scale factor of the dilation is given as follows:

Answer: The third one

Step-by-step explanation:

That system has the same equation, but a different solution, meaning the lines can never intersect.

We can also convert it into slope-intercept form.

y = -2x + 9

y = -2x + 5

Different slope and same y-intercept = NO SOLUTION

Answer:

2x + y = 9

2x + y = 5

Step-by-step explanation:

No solutions for 2 lines will only happen when the lines are parallel and never touch.  So there are no solutions.

Lines are parallel when slopes are the same.

The equations cannot be the same just the slopes are the same.  

Let's rearrange this set of equations into y=mx+b so we can see what the slope m is:

2x + y = 9           and               2x + y = 5

y= -2x +9                                 y= - 2x +5

You can see the lines are different but have the slopes so they are parallel and no solutions.

Answer:

Step-by-step explanation:

Answer:

y = -3/4x + 6.75

Step-by-step explanation:

Slope intercept form is y = mx + b, where m is the slope and b is the y intercept.

Plug in the given point and slope into the equation, then solve for b:

y = mx + b

3 = -3/4(5) + b

3 = -3.75 + b

6.75 = b

Then, plug in the slope and y intercept into the equation:

y = -3/4x + 6.75 is the equation of the line in slope intercept form

Doing simple algebra with the two summations we can see that:

\(\Sigma x = 799\\\\\Sigma x^2 = 7,188\)

First, we know that there are 97 passengers, and we know that the summation:

\(\Sigma (x - 5) = 314\)

Where x represents the weights.

Then we can rewrite that sum as:

\(\Sigma (x - 5) = \Sigma x - 97*5\)

And replace that in the original equation to get:

\(\Sigma x - 97*5 = 314\\\Sigma x = 314 + 5*97 = 799\)

So that is the first summation, now let's get the second one,  we can rewrite the summation as:

\(\Sigma (x - 5)^2 = \Sigma x^2 - 10x +25 \\\\\Sigma x^2 - \Sigma 10x + \Sigma 25\)

Where remember we have 97 terms, and the summation is equal to 1623, then:

\(\Sigma x^2 - \Sigma 10x + 25*97 = 1623\)

Now we can replace the second term by the thing we found earlier:

\(\Sigma x^2 - 10\Sigma x + 25*97 = 1623\\\\\Sigma x^2 - 10*799 + 25*97 = 1623\\\\\Sigma x^2 = 1623 + 10*799 - 25*97\\\\\Sigma x^2 = 7,188\)

Using one of the circle theorems, the measure of angle CDE is 77°. The correct option is the D. 77°

From the question, we are to determine the measure of angle CDE

To determine the measure of angle EAC, we will first determine the measure of angle EAC.

In the given diagram,

m ∠EAC = 90° + 64°

m ∠EAC = 154°

Now, from one of the circle theorems,

The angle at the center of a circle is twice the angle at teh circumference

We can write that

m ∠EAC = 2 × m ∠CDE

Therefore,

m ∠CDE = 1/2 × m ∠EAC

m ∠CDE = 1/2 × 154°

m ∠CDE = 77°
