Answer:

The missing y -coordinate is 0.

Step-by-step explanation:

Here we know the slope but must find the y-coefficient of one of the points.

y - 2

The slope is m = 1/2 = rise / run = ----------

3 - 7

y - 2

or 1/2 = ---------- which simplifies to -2 = y - 2, which yields y = 0.

-4

The missing y -coordinate is 0.

Type A is 2 feet tall and grows at a rate of 17 inches per year. Type B is 10 feet tall and grows at a rate of 5 inches per year

Svetllana [295]

Answer:

Therefore after 3 years the height of these tree will be same.

Step-by-step explanation:

Given that,

Type A is 2 feet tall and grows at a rate of 17 inches.

Type B is 10 feet tall and is growing at a rate of 5 inches.

1 feet = 12 inches,

2 feet= (12×2) inches = 24 inches

5 feet= (12×5) inches = 60 inches

Let after t years, the height of these tree will be same.

After t years, the height of type A is =(24+17t)

After t years, the height of type B is =(60+5t)

According to the problem,

24+17t=60+5t

⇒17t-5t=60-24

⇒12t = 36

⇒t = $\frac{36}{12}$

⇒t=3

Therefore after 3 years the height of these tree will be same.

Answer:

Step-by-step explanation:

We know that a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

5^2 + 12^2 = c^2

25+144 = c^2

169 = c^2

Taking the square root of each side

sqrt(169) = sqrt(c^2)

13 =c

If AX) = x2 + 2x + 3, what is the average rate of change of AX) over the interval (-4, 6]? OA 51 B. 40 OC. 31 OD 20 OE 4

Yuki888 [10]

Answer:

Step-by-step explanation:

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

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b ] = [ - 4, 6 ] , then

f(b) = f(6) = 6² + 2(6) + 3 = 36 + 12 + 3 = 51

f(a) = f(- 4) = (- 4)² + 2(- 4) + 3 = 16 - 8 + 3 = 11 , thus

average rate of change = $\frac{51-11}{6-(-4)}$ = $\frac{40}{10}$ = 4 → E
