Answer:

Step-by-step explanation:

y = $\frac{1}{4}$ is the equation of a horizontal line, parallel to the x- axis.

A line perpendicular to it will be a vertical line parallel to the y- axis with equation

x = c

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

The line passes through (- 6, - 9) with x- coordinate - 6, thus

x = - 6 ← is the equation of the perpendicular line

Answer:

$\huge\boxed{x^3-4x^2+x-4=(x-4)(x^2+1)}$

Step-by-step explanation:

$x^3-4x^2+x-4\qquad\text{distributive}\\\\=x^2(x-4)+1(x-4)\\\\=(x-4)(x^2+1)\\\\/x^2+1-\text{is prime}/$

In most linear programming problems, there are two stages:

xxMikexx [17]

Answer: Bruno = 16 cans, Blaze = 14 cans

<u>Step-by-step explanation:</u>

Part A gave you the three equations.

Part B showed you the intersected points --> (16, 14), (20, 10), & (21.4, 10.7)

Part C is giving you the Cost function: C(x, y) =0.10x + 0.20y

Input the intersected points into the Cost function to find the maximum.

C(16,14) = 0.10(16) + 0.20(14)

= 1.60 + 2.80

= 4.40

C(20,10) = 0.10(20) + 0.20(10)

= 2.0 + 2.00

= 4.00

C(21.4,10.7) = 0.10(21.4) + 0.20(10.7)

= 2.14 + 2.14

= 4.28

Of the three results we just found, 4.40 is the biggest value.

So, the maximum occurs at C(16,14) = 4.40

If Seth traveled 1 mile in 57.1 seconds. About how fast does Seth travel in miles per hour?

irga5000 [103]

Answer: Seth is travelling at 63.047mi/hr

Step-by-step explanation: First convert 57.1 seconds to hours.

1 hour is equal to 3600s so multiply 57.1sec by 1hr/3600s to get 0.0158 hr

The formula for speed distance over time. v=d/t

v= 1mi/0.0158hr

v= 63.047mi/hr

Evaluate the following function: Show all work! h(x)=3x²+2-2x, Find h(-2)

Mkey [24]

<h2><u>Polynomial Function</u></h2>

<h3>Evaluate the following function: Show all work! h(x)=3x²+2-2x, Find h(-2)</h3>

To determine the answer, substitute the given value to the function and simplify.

h(x) = 3x² + 2 - 2x; h(-2)
h(-2) = 3(-2)² + 2 - 2(-2)
h(-2) = 3(4) + 2 + 4
h(-2) = 12 + 2 + 4
h(-2) = 14 + 4
h(-2) = 18

<u>Answer:</u>

<u>18</u> is the answer.
