Answer:

see explanation

Step-by-step explanation:

(a)

A horizontal line parallel to the x- axis has equation

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through (- 2, 4) with y- coordinate 4, thus

y = 4 ← equation of horizontal line

(b)

A vertical line parallel to the y- axis has equation

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (- 2, 4) with x- coordinate - 2, thus

x = - 2 ← equation of vertical line

0.18<0.70

18%<0.7

0.7 is larrger because math

Given the arithmetic sequence an = −5 + 3(n − 1), what is the domain for n?

Airida [17]

D because for a sequence you can't have a -1st term so b is out and a and c mean the same thing so neither of them can be the answer

With work please!!!<br><br> f(x) = -x^4 + 5x - 4x^2<br><br> (f (2))^2

marishachu [46]

Answer: 484

===============================================

Work Shown:

First let's compute f(2). We replace every x with 2 and then use PEMDAS to simplify

f(x) = -x^4 + 5x - 4x^2

f(2) = -(2)^4 + 5(2) - 4(2)^2

f(2) = -16 + 5(2) - 4(4)

f(2) = -16 + 10 - 16

f(2) = -6 - 16

f(2) = -22

Then we square this result to find the value of $[ f(2) ]^2$

$f(2) = -22\\\\\left[ f(2) \right]^2 = [ -22 ]^2\\\\\left[ f(2) \right]^2 = 484$

A triangle has a hypotenuse that is 65 inches, and the length of one of its legs is 25 inches. What is the length, in inches, of

algol [13]

Answer:

okay so the way your going to set this up is backwards because you already know your hypotenuse. 65^2 = 25^2 + b^2. So its 24 feet
