Answer:

The predicted GPA is then y = 0.149(15) + 0.89 = 3.125

Step-by-step explanation:

Although you don't specifically say so, the equation you provide here is probably a "best fit" equation based upon data:  GPA versus number of hours of study per week.

Here, y = 0.149x + 0.89 and the number of study hours of interest is 15.

The predicted GPA is then y = 0.149(15) + 0.89 = 3.125

What is the product of a+3 and −2a2+15a+6b2?
Lady bird [3.3K]

Answer:

c. 2a3+9a2+45a+6ab2+18b2

Step-by-step explanation:

(a+3) + (−2a2+15a+6b2)

Using distributed p. with and a and 3

a(−2a2) + a(15a) +a(6b2)        and       3(−2a2) + 3(15a) + 3(6b2)

= -−2a3 + 15a2 + 6ab2                          = -6a2 + 45a + 18b2

Now add like terms and put in standard form.

15a2+(-6a2) = 9a2  

And equals

-2a3 + 9a2+45a+6ab2+18b2

Trust me I took the test and got 100%

Makovka662 [10]

if one customer shows up, and she buys one song, that's $1.29, if she doesn't buy anymore, then that's the charge.

the first song is always at a full price, and after that, to encourage buying, the next ones are just 99 cents, let's see how it goes after a few songs purchases.

1 song.........................$1.29

2 songs.......................$1.29 + 0.99(2)

3 songs.......................$1.29 + 0.99(3)

4 songs.......................$1.29 + 0.99(4)

c songs.......................$1.29 + 0.99(c)

s(c) = 1.29 + 0.99c.

If the endpoints of the diameter of a circle are (−10, −8) and (−6, −2), what is the standard form equation of the circle? A) (x
kolbaska11 [484]
Selections B and D both appear to be appropriate.
  B) (x+8)² + (y+5)² = 13
  D) (x+8)² + (y+5)² = 13

_____
The center is at the midpoint of the diameter, ((-10-6)/2, (-8-2)/2) = (-8, -5). For center (h, k) and radius r, the equation is
  (x -h)² +(y -k)² = r²
  (x -(-8))² +(y -(-5))² = (√13)²
  (x+8)² + (y+5)² = 13
