If BE = 10x - 12 and EF = 2x, Find AC

Answer: $41.62

Step-by-step explanation:

let the price of the jacket be X

then the price of belt will be X-8.61

according to question

X + X-8.61 = 91.85

2X - 8.61 = 91.85

2X = 91.85 + 8.61

2X = 100.46

X = $50.23

cost of jacket = $ 50.23

cost of belt = $ 41.62

Hope this helps!!!

Answer: $41.62

Step-by-step explanation:

*j = jacket*  *b = belt*
belt + jacket = 91.85 (the total cost of the belt and jacket)
belt = jacket - 8.61 (the price of the belt is $8.61 less than the jacket)

We can use substitution to solve for the value of b.
Substitute the second equation into the first equation:
(j - 8.61) + j = 91.85

Simplify by combining like terms:
2j - 8.61 = 91.85
Add 8.61 to both sides:
2j = 100.46
Divide both sides by 2:
jacket = 50.23

b = j - 8.61

b = 50.23 - 8.61

b = 41.62

Answer:

[tex]y = 4d + 8\\[/tex]

Step-by-step explanation:

Since d is the number of large drinks, and there is always a constant of 1 large popcorn, we go to (0, 8). This concludes that since we start off with the cost of 8 dollars with no large drink but a large popcorn, the popcorn will stay a constant cost of $8. (the equation for this scenario is as shown):

y = md + 8

y (total cost)

m (coefficient - in this sense the cost of the drinks.)

d (amount of drinks)

8 (the constant of 8 represents the cost of one large popcorn consistently)

Now, lets find the cost of the dink.

Go to (1, 12).

$12 dollars is the total cost, with one drink and one large popcorn bought.

We have already discussed that we will have a constant of 8 because no matter the amount of drinks we will get, we would have bought 1 large popcorn at $8.

Therefore, we must subtract 8 dollars from 12.

12 - 8 = 4

From the total cost of everything we bought (2 things) and subtracting it with the cost one of the things we bought, we get the cost of the other thing.

each drink will cost $4.

Therefore, with all the variables and their listed meanings, this will be our given equation:

y = 4d + 8

The Panther I traveled approximately 2413 miles before reaching a speed of 130 mph.

A trapezoid is a quadrilateral having two parallel bases and one set of other sides called legs.

To estimate the distance traveled by the Panther I, we need to approximate the area under the velocity curve between 0 and 25.7 seconds. We can divide the area into trapezoids using the data given in the table.

The first trapezoid has a height of 30 mph and a base of 1.8 seconds. The second trapezoid has a height of 40 mph and a base of 1.3 seconds (the difference between 3.1 and 1.8).

Continuing in this way, we get the following table:

Speed       Height

Range    (mph) Base (s)  Area (mph * s)

0-30  30           1.8               54

30-40 40           1.3               52

40-50 50           1.1            55

50-60 60           1.3              78

60-70 70           1.9            133

70-80 80           1.8             144

80-90 90            2.3            207

90-100 100           3.1            310

100-120 120          6.3            756

120-130 130           4.8            624

To find the total area, we add up the areas of all the trapezoids:

54 + 52 + 55 + 78 + 133 + 144 + 207 + 310 + 756 + 624 = 2413

Therefore, the Panther I traveled approximately 2413 miles before reaching a speed of 130 mph.

The function g(x) is translation of f(x) 9 units up. The solution has been obtained by using transformation.

An operation known as a transformation involves moving a polygon or other two-dimensional object on a plane or coordinate system.

We are given that the function g(x) is a translation of the function

f(x) = x².

In the graph, we can see that the vertex of the parabola is at (0, 9).

This means that the function g(x) is 9 units up from the function f(x).

So, g(x) = x² + 9

Hence, the function g(x) is translation of f(x) 9 units up.

The length of the line segment that connects points at (5, 4) and (−3, −1) is found to be 9.43 units.

Using the formula obtained from Pythagoras' theorem, distance can be computed.

The distance formula in coordinate geometry is:

(P, Q) = √ (x2 – x1)² + (y2 – y1)².

Given points: (5, 4) and (−3, −1)

d = √ (-3 - 5)² + (4 + 1)²

d = √ 64 + 25

d = √ 89

d = 9.43

The measure of side AC of the right triangle is 7.2 units.

The figure in the image is the of a right triangle.

To solve for the measure of side AC, we use trigonometric ratio.

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

Tangent = Opposite / Adjacent

tan( A ) = BC / AC

Plug in the values and solve for side AC.

tan( 51° ) = 8.9 / AC

AC = 8.9 / tan( 51° )

AC = 8.9 / 1.234897

AC = 7.2

Therefore, side AC has a value of 7.2 units.

In the polynomial function given, the value of the limit as it approached infinity is 5/3

To evaluate this limit, we need to determine the behavior of the function as x approaches infinity. To do this, we can use the fact that for any polynomial p(x) and q(x) of the same degree, the limit of p(x)/q(x) as x approaches infinity is equal to the ratio of the leading coefficients.

In this case, both the numerator and denominator are polynomials of degree 2, so we can apply this property. The leading coefficient of the numerator is 6 and the leading coefficient of the denominator is 7. Therefore, the limit as x approaches infinity of the given expression is:

lim [ (6x² - 5) / (7x² + x - 3)]

According to the Cartesian plane graph, it can be inferred that the circle was rotated and translated (option B).

To identify the movements that were made to circle 1 to become 2 we must carefully observe the graph. Once we have analyzed this graph we can infer the movements that were made to the circle. In this case, the rotation was performed because it can be seen that it was rotated having the coordinate (-1.5, 0.5) as a reference or point of rotation.

However, it was also translated because it was shifted a bit down and to the left. So the correct answer would be option B.

The given figure is made up of a cone and a hemisphere , so to find the total volume , we would find the volume of cone and hemisphere individually and add them up to find the net volume.

Finding volume of cone:

The data we have is ,

As we know that the volume of cone is given by,

[tex]\implies V =\dfrac{1}{3}\pi r^2 h \\[/tex]

on substituting the respective values,we have;

[tex]\implies V =\dfrac{1}{3}\times 3.14 \times (9in.)^2 \times 14in .\\[/tex]

[tex]\implies V = \dfrac{1}{3}\times 3.14 \times 81in.^2\times 14in. \\[/tex]

[tex]\implies V = 1186.92 \ in.^3 \\[/tex]

Finding the volume of hemisphere:

As we know that the volume of hemisphere is given by;

[tex]\implies V =\dfrac{2}{3}\pi r^3 \\[/tex]

And here ,

So that;

[tex]\implies V =\dfrac{2}{3}\times 3.14\times (9\ in.)^3 \\[/tex]

[tex]\implies V =\dfrac{2}{3}\times 3.14\times 729\ in.^3 \\[/tex]

[tex]\implies V = 1526.04 \ in.^3 \\[/tex]

Hence the total volume will be ,

[tex]\implies V_{prop} = (1526.04 + 1186.92 )in.^3\\[/tex]

[tex]\implies V = 2712.96 \ in.^3 \\[/tex]

Hence the volume of prop is 2713 in.³

and we are done!

Step-by-step explanation:

To calculate the volume of the prop, sum the volume of the cone and the volume of the half-sphere.

[tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a cone}\\\\$V=\dfrac{1}{3} \pi r^2 h$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $h$ is the height.\\\end{minipage}}[/tex]     [tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a half-sphere}\\\\$V=\dfrac{2}{3} \pi r^3$ \\\\ where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\\end{minipage}}[/tex]

Therefore, the equation for the volume of the prop is:

[tex]V_{\sf prop}=\dfrac{1}{3} \pi r^2 h+\dfrac{2}{3} \pi r^3[/tex]

From inspection of the given diagram:

Substitute the values of r, h and π into the equation and solve for V:

[tex]\begin{aligned}\implies V_{\sf prop}&=\dfrac{1}{3} \pi r^2 h+\dfrac{2}{3} \pi r^3\\\\&=\dfrac{1}{3} (9)^2 (14)+\dfrac{2}{3} \pi (9)^3\\\\ &=\dfrac{1}{3} \pi (81) (14)+\dfrac{2}{3} \pi (729)\\\\ &=378 \pi+486 \pi\\\\ &=864 \pi\\\\&=864 \cdot 3.14\\\\&=2712.96\\\\&=2713.0\;\sf in^3\;\;(nearest\;tenth)\end{aligned}[/tex]

Therefore, the volume of the prop is 2,713.0 in³ to the nearest tenth.
