Multiply (2x^2+4x-3)(x^2-2x+5)

1 answer:

8 0

To answer this, you just go around multiplying the terms from the first set by everything in the second set. (For example, multiply 2x^2 by x^2, next by -2x, and finally by 5)

The ratio of the measures of the sides of a

ANTONII [103]

Answer:

The length of the sides are 8 , 32 , 36

Step-by-step explanation:

Ratio of sides = 2 : 8 : 9

The sides are 2x , 8x , 9x

Perimeter of triangle = 76 inches

2x+ 8x + 9x = 76

19x = 76

x = 76/19

x = 4

2x = 2*4 = 8

8x = 8 * 4 = 32

9x = 9 * 4 = 36

in right triangle ABC, C is the right angle. Given measure of angle A = 40 degrees and a =6, which of the following are the leng

qaws [65]

Tan 40° = 6 / AC
AC = 6 / tan 40°
AC = 6 / .8391
AC = 7.15

AB² = 6² + 7.15²
AB² = 36 + 51.123
AB² = 87.12
AB = 9.33

Consider the function f(x) = x^{2/3} on the interval [-1,8].

zhannawk [14.2K]

The right option is (c). The Mean Value Theorem does not apply since f(x) is not differentiable on (-1,8). Because the derivative of f is 2/3 x^(-1/3) which is undefined at x=0.So, that would imply that it is not differentiable along the interval.
