Evaluate the function for x = –4c if c = –2.

1 answer:

5 0

x = –4c
if c = -2 then x = -4(-2) = 8

I believed you had a typo, function should be f(x) = -3x^2 - 4x
so
f(x) = -3x^2 - 4x
f(x) = -3(8^2) - 4(8)
f(x) = -3(64) - 32
f(x) = -192 - 32
f(x) = -224

answer

C.
–224

Answer:

The corn plant grew by 11.17 inches during week 2.

Step-by-step explanation:

7 and 1/3 inches tall at the end of Week 1.

The height at the end of week 1, as a simple fraction, is:

$7 + \frac{1}{3} = \frac{3*7 + 1}{3} = \frac{22}{3}$

The corn plant was 18 1/2 inches tall at the end of Week 2.

At the end of week 2, the height will be of:

$18 + \frac{1}{2} = \frac{18*2+1}{2} = \frac{37}{2}$

How many inches did the corn plant grow during Week 2?

Height at the end of week 2 subtracted by the height at the end of week 1. So

$\frac{37}{2} - \frac{22}{3} = \frac{3*37-2*22}{6} = \frac{67}{6} = 11.17$

The corn plant grew by 11.17 inches during week 2.

Answer:

The values of $x$ so that $y = \csc x$ have vertical asymptotes are $-2\pi$ , $-\pi$ , $0$ , $\pi$ , $2\pi$ .

Step-by-step explanation:

The function cosecant is the reciprocal of the function sine and vertical asymptotes are located at values of $x$ so that function cosecant becomes undefined, that is, when function sine is zero, whose periodicity is $\pi$ . Then, the vertical asymptotes associated with function cosecant are located in the values of $x$ of the form:

$x = 0\pm \pi\cdot i$ , $\forall \,i\in \mathbb{N}_{O}$

In other words, the values of $x$ so that $y = \csc x$ have vertical asymptotes are $-2\pi$ , $-\pi$ , $0$ , $\pi$ , $2\pi$ .
