Step-by-step explanation:

Method 1: The area of a trapezoid is

A = (8 + 17) / 2 x 12 = 150 square feet

Method 2: You can also split it into a rectangle and a triangle.

12 x 8 + 12 x (17 - 8)/2 = 150 square feet

Answer:

The graph has random dots all over

Step-by-step explanation:

Answer:

d. 40 feet

Step-by-step explanation:

Perimeter = 140 ft

Width = L + 10

P = 2w + 2L

140 = 2(L + 10) + 2L

140 = 2L + 20 + 2L

120 = 4L

L = 30

w = L + 10

w = 30 + 10

w = 40

Answer:

The Area of the Grass is 18 square meters.

Step-by-step explanation:

Find the area of the grass and sand (5*6). The area of the grass and sand is 30.

Next, find the area of just the sand (3*4). The area of the sand is 12.

Subtract the area of the sand (12) from the area of the grass and sand (30).

30-12 = 18

The relationship modeled that has the function of  f(x) = 4x³ - 72x² + 320x is known to be the volume of a right prism that has its dimensions to be : 4 times  of its desired length, 10 units lower that its desired length, and 8 units lower than its desired length.

For us to know the relationship modeled by the above function, the best way to do it is for one to factor it.

The function is: f(x) = 4x³ - 72x² + 320x

First. we factor it so as to extract the common factor 4x:

Secondly,  we factor the quadratic trinomial.

This is often done by writing it as a product of two binomials where the two constant terms are said to be sum up - 18 and its product is said to be 80.

The above terms are known to be -10 and - 8; so the two factors are said to be (x - 10) and (x - 8).

Therefore The relationship modeled that has the function of  f(x) = 4x³ - 72x² + 320x is known to be the volume of a right prism that has its dimensions to be : 4 times  of its desired length, 10 units lower that its desired length, and 8 units lower than its desired length.

Where it has :

x = the desired  length,

4x = 4 times its desired length,

x - 10 = 10 lower than its desired length,

x - 8 = 8 lower than its desired length,

We can therefore say that the volume of the prism is said to be the product of the three factors which are:

V = (4x)(x-10)(x-8)

Every summer, Richard plants a garden on a rectangular plot of land.

Last summer, Richard's garden measured 45 feet in length and 18 feet in width.

This summer, Richard decides to resize his garden by decreasing the length of the garden, and increasing the width of the garden by two times the length reduction.

The area of this year's garden, A(x), can be modeled by a quadratic function, where x is the number of feet that the length is reduced.

Length = (45 – x)

Width = (18 + 2x)

Then the maximum potential area of this year's resized garden will be

A(x) = (45 – x)(18 + 2x)

A(x) = 810 + 72x – 2x²

A(x) = 2(405 + 36x – x²)

For maximum potential, A'(x) = 0

    A'(x) = 0

36 - 2x = 0

       2x = 36

         x = 18

Then the maximum potential area will be

A(x) = 2(405 + 36 × 18 – 18²)

Cost of per session the average rate is $45.

Step-by-step explanation:

It is given that a gym membership with two personal training session cost $125, while gym membership with five personal training sessions cost $260.

It is required to find what is the cost per session.

Step 1 of 1

It is given that a gym membership with two personal training session cost $125, while gym membership with five personal training sessions cost $260.

To find the cost of per session calculate the average rate.

Now let $f(x)$ be the cost per session use the for the average rate of change, and the input value is the number of personal traings x.

[tex]$m=\frac{f\left(x_{2}\right)-f\left(x_{1}\right)}{x_{2}-x_{1}}$$[/tex]

Now substitute, $125 for [tex]$f\left(x_{2}\right)[/tex], 260 for [tex]$f\left(x_{1}\right), 2$[/tex] for [tex]$x_{1}$[/tex] and 5 for [tex]$x_{2}$[/tex] then,

[tex]$m=\frac{260-125}{5-2}$\$$\begin{aligned}&=\frac{135}{3} \\&=45\end{aligned}$$[/tex]

Cost of per session the average rate is $45.

The unit rate of 187pounds of food for 1447.38 is 7.74 per pound

Unit rate = Total cost of food ÷ Quantity of food

The solution to the division of the given surd is: [tex]\mathbf{P =\dfrac{(6\sqrt{x}-x^2\sqrt{x}-3x\sqrt{x}+2x+2)(x-1) }{8x} }[/tex]

The division of surds follows a systemic approach whereby we divide the whole numbers separately and the root(s) are being divided by each other.

Given that:

[tex]\mathbf{P=(\frac{\sqrt{x} +2}{x-1}+\frac{\sqrt{x}\\ -2}{x-2\sqrt{x} +1} ) : \frac{4x}{(x-1)^{2} }}[/tex]

[tex]\mathbf{=\dfrac{(\frac{\sqrt{x} +2}{x-1}+\frac{\sqrt{x}\\ -2}{x-2\sqrt{x} +1} )}{ \frac{4x}{(x-1)^{2} }} }[/tex]

Using the fraction rule:

[tex]\mathbf{\dfrac{a}{\dfrac{b}{c}}= \dfrac{a\times c}{b}}[/tex]

[tex]\mathbf{\implies \dfrac{(\frac{\sqrt{x} +2}{x-1}+\frac{\sqrt{x}\\ -2}{x-2\sqrt{x} +1} )(x-1)^{2}}{4x}} }[/tex]

Step-by-step explanation:

Because the two angles at the bottom of both the triangles are congruent, the two triangles are similar. Therefore, the corresponding side lengths of the triangles must be proportional to each other

if the area of a triangle is hb/2,

(with h=length of height, b=length of base)

the height of the first triangle is:

25 = 10h/2

50 = 10h

h=5

you can write ratios representing the proportions of the two triangles:

5/x = 10/12 (with x=height of second triangle)

x=6

then find the area of the second triangle with the height (6) and base (12)
