Answer:
- 1
Step-by-step explanation:
f(x) + g(x) = - 2x² + 1 + 3x = - 2x² + 3x + 1
Substitute x = 2 into the expression for f(x) + g(x)
= - 2(2)² + 3(2) + 1 = - 8 + 6 + 1 = - 1
19/2 = 9.5
(9.5)^2 = 90.25 = 9 + 81.25
x^2 - 19x + 9 = 0
x^2 - 19x + 90.25 - 81.25 = 0
(x - 9.5)^2 = 81.25
x - 9.5 = +/-sr(81.25)

The formula in computing the area of the circle is:
A = pi (r)^2
Where r = the radius of the circle
Since you are only given the diameter of the circle, you
have to solve for its radius. The radius of the circle is half its diameter. Therefore,
the radius of the circle is 5 (10/2).
Now, you substitute the measurements to the formula:
A = 3.14 (5)^2
A = 3.14 (25)
A = 78.5 sq. units
Answer:
G(x)=x^3-1
Step-by-step explanation:
Надеюсь тебе это поможет
Just put them in order from least to greatest and find out in between which number to put them . For example put 24 between 20 and 25.
Hope that helps .
