Find the slope of the line that passes through the point (4,8) and (3,-3)

Marta_Voda [28]

Answer:

I don't think it's possible for this to be a decimal because the slope is positive 11.

Step-by-step explanation:

Use slope formula. x2-x1/y2-y1. Since we always go with the smaller x value we do 8-(-3) / 4-3/ We'll get 11 for 8-(-3) and we'll get 1 for 4-3/ so that leaves us with 11/1 which can't be simplified and has no decimal.

The range of the function f(k) = k2 + 2k + 1 is {25, 64}. What is the function’s domain?

Lunna [17]

The domain of a function contains the x-values of the function while the range of the function contains the y-values of the function. In this case, we substitute 25 and 64 to y. Then,
25 = k2 + 2 k + 1 (k-4) * (k+6) = 0
64 = k2 + 2 k + 1 (k-7) * (k+9) = 0
hence the domain is {-9,-6, 4,7}

Can someone plz answer this correctly and quickly.

V = $\pi \pi$ $r^{2}$ h

1. Find the radius.

8/2 = 4

2. Square the radius.

$4^{2}$ = 16

3. Multiply that by pi.

3.14 * 16 = 50.24

4. Multiply that by the height.

50.24 * 20 = 1004.8

5. Now find 60% of that.

1004.8 * 0.6 = 602.88

V = 602.88 $m^{3}$

Honestly, it's been a while since I've done this, but I believe this is the answer.
