Answer:
$48.22
Step-by-step explanation:
I'm pretty sure you just multiply the 1627.4 by 3%
1627.40*.03=48.822 = $48.22

Answer: 16</h3>
=============================================================
Explanation:
Equate s(t(x)) and s(1) to find that t(x) = 1 must be the case.
Let's find what x must be.
t(x) = 3x-8
1 = 3x-8
1+8 = 3x
9 = 3x
3x = 9
x = 9/3
x = 3
So plugging x = 3 into t(x) gets us t(x) = 1
In other words, t(3) = 1
So that tells us s(t(3)) = s(1)
-------------
Let's plug x = 3 into the s(t(x)) equation
s(t(x)) = x^2 + 3x - 2
s(t(3)) = (3)^2 + 3(3) - 2
s(1) = 9 + 3(3) - 2
s(1) = 9 + 9 - 2
s(1) = 18 - 2
s(1) = 16
Answer:
is the last one
Step-by-step explanation:
the line is dotted and shaded above
None of the statements are true,
Proof:
Solve for x over the real numbers:
2 x^2 + 12 x = 32
Subtract 32 from both sides:
2 x^2 + 12 x - 32 = 0
2 x^2 + 12 x - 32 = 2 (x^2 + 6 x - 16):
2 (x^2 + 6 x - 16) = 0
Divide both sides by 2:
x^2 + 6 x - 16 = 0
x = (-6 ± sqrt(6^2 - 4 (-16)))/2 = (-6 ± sqrt(36 + 64))/2 = (-6 ± sqrt(100))/2:
x = (-6 + sqrt(100))/2 or x = (-6 - sqrt(100))/2
sqrt(100) = sqrt(4×25) = sqrt(2^2×5^2) = 2×5 = 10:
x = (-6 + 10)/2 or x = (-6 - 10)/2
(-6 + 10)/2 = 4/2 = 2:
x = 2 or x = (-6 - 10)/2
(-6 - 10)/2 = -16/2 = -8:
Answer: x = 2 or x = -8
