Answer:

162 ft^3

Step-by-step explanation:

volume = area of base * height

V = 22 1/2 ft^2 * 7 1/5 ft

Change the mixed numerals into fractions.

V = 45/2 ft^2 * 36/5 ft

Multiply the fractions.

V = 45/2 * 36/5 ft^3

Switch the denominators.

V = 45/5 * 36/2 ft^3

Simplify each fraction.

V = 9 * 18 ft^3

V = 162 ft^3

Answer:

f(1) = 4

Step-by-step explanation:

f(1)  means let x=1 and find the y value at that point on the graph

At x=1 there is an open circle and a closed circle.  The open circle means that the function does not have a value at that point, so we use the closed circle

f(1) = 4

Answer:

x=5

Step-by-step explanation:

First off, you need to subtract 67 from 17 to get the variable alone.

That will leave you with -10x=-50

Then you need to divide -10 and -50,

Two negatives make a positive so

x=5

Answer:

We have the value as;

8x/5

Step-by-step explanation:

Here, we want to get the breakdown of the given expression

We have (x^2 - 9) as (x-3)(x + 3)

So we have;

2x/(x + 3) * (x-3)(x+3)/5 * 4/(x-3)

= 2x * 4/5= 8x/5

Answer:

170

Step-by-step explanation:

If you look at the other angle it says 20 and a whole circle would be 360 so subtract 360-130 then after that since the angle takes 2 part or however you may say that means u subtract 60 (20+20+20 thee open angle) this means you get 170 (i think im unsure but you can try)

Answer:

hi the answer is 29

Step-by-step explanation:

Answer:

29

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

The average rate of change of h(x) in the closed interval [ a, b ] is

[tex]\frac{f(b) - f(a)}{b-a}[/tex]

Here [ a, b ] = [ - 2, 4 ] , then

f(b) = f(4) = - (4)² + 4(4) + 12 = - 16 + 16 + 12 = 12

f(a) = f(- 2) = - (- 2)² + 4(- 2) + 12 = - 4 - 8 + 12 = 0

Then

average rate of change = [tex]\frac{12-0}{4-(-2)}[/tex] = [tex]\frac{12}{6}[/tex] = 2

Answer and Step-by-step explanation:

The answer is A.

y = x + 2 and y = -2x + 4

This is because:

- The graph going from left to right matches the first equation, in which the graph has a slope of 1 and has a y-intercept at (0, 2).

- The graph going from right to left matches the second equation, in which the graph has a slope of -2 (Since it is going from right to left), and has a y-intercept at (0, 4).

#teamtrees #PAW (Plant And Water)

Answer:

5.56 m

Step-by-step explanation:

Circumference = 2πr

r is the radius, however the diameter is given. The radius is half the diameter. So the radius is:

1.8 ÷ 2 = 0.9

Circumference = 2 × π × 0.9

= 5.56 m ( in 3 significant figures )

c= 7.17

Variable "c" is independent because it does not change. Jim receives $7.17 back.

Answer:

y - 2x = 3

Step-by-step explanation:

Use the point-slope formula y - k = m(x - h), with h = 0, k = 3 and m = 2:

y - 3 = 2(x - 0), or

y - 3 = 2x, or

y - 2x = 3

Note that the given point, (0, 3), is the y-intercept of this line, and so we immediately know b in y = mx + b:  it is 3.

==========================================================

Explanation:

Match up (7x+3)(7x-3) with (a+b)(a-b)

We have

We can see that a = 7x and b = 3

Furthermore, we can say,

(a+b)(a-b) = a^2 - b^2

(7x+3)(7x-3) = (7x)^2 - (3)^2

(7x+3)(7x-3) = 49x^2 - 9

The values of a and b are 7x and 3 respectively

(7x+3) (7x−3)

Using the format

(a + b)(a − b) = a² − b²

Therefore,

a = 7x

b = 3

Therefore,

From (a + b)(a − b) = a² − b²

(7x+3) (7x−3) = (7x)² - 3²

(7x+3) (7x−3) = 49x² - 9

Answer:

x² + (y + 8)² = 81

Step-by-step explanation:

Centre (h,k) = (0,-8)

radius (r) = 9

(x - h)² + (y - k)² = r²

(x - 0)² + (y + 8)² = 9²

x² + (y + 8)² = 81

Answer:

[tex]t=\dfrac{d}{s}[/tex]

Step-by-step explanation:

Dan is driving with an average speed of s. He is driving a total distance of d.

The average speed of an object is given by :

Average speed = total distance/total time

Let b the time of his trip

So,

[tex]s=\dfrac{d}{t}\\\\or\\\\t=\dfrac{d}{s}[/tex]

So, the formula for the total time of his trip is [tex]\dfrac{d}{s}[/tex].
