19) Amount of oil in = amount of oil in final product

.025(x) + .09(40-x) = .055(40) (x = 2.5% amt 40 - x = 9% amt)

x = 21.54 L of 2.5 % then 9% = 18.46 L

Determine the functions value when x= -1?a. g(-1) = -3b. g(-1) = 0c. g(-1) = 1d. g(-1) = 27

Ber [7]

Problem

Determine the functions value when x= -1?

a. g(-1) = -3

b. g(-1) = 0

c. g(-1) = 1

d. g(-1) = 27

Solution

For this case we just need to find the value of g when x= -1 and if we look at the table we got:

g(-1)= (-1)^3 + 6(-1)^2 +12(-1) +8

g(-1)= -1 +6 -12+8 = 5-12+8= 1

And then the solution for this case would be:

c. g(-1) = 1

Syrus is buying a tent with the dimensions shown below. The volume inside the tent is 4.5\text{ m}^34.5 m 3 4, point, 5, start t

Vika [28.1K]

Answer:

2 meters

Step-by-step explanation:

Given

$Volume = 4.5m^3$

The question is incomplete as the picture of the tent is not attached.

However, I will use the attached figure to answer the question.

From the attachment, we have:

$b = 1.5m$ --- base of the tent

$l = 3m$ --- length of the tent

Required

Determine the height of the tent

The volume of the tent is:

$\frac{1}{2} * bhl = Volume$

Where h is the required height.

So, we have:

$\frac{1}{2} * 1.5 * h * 3 = 4.5$

$\frac{1}{2} * 1.5 * 3 * h = 4.5$

$\frac{1}{2} * 4.5 * h = 4.5$

Make h the subject

$h = \frac{4.5 * 2}{4.5}$

$h = 2m$

<em>The height of the tent is 2m</em>

Calculate the value of 0. Write your equation.

Crazy boy [7]

Answer:

θ = 67.4°

Step-by-step explanation:

using the <u>SOHCAHTOA </u>method,

Here opposite is 12 cm, hypotenuse is 13 cm, adjacent is 5 cm.

Using the formula:

$sin(\beta ) = \frac{oppsoite }{hypotenuse}$

$sin(\beta ) = \frac{12}{13}$

$\beta = sin^{-1}(\frac{12}{13} )$

β = 67.4°

Really don’t understand this question

Ilya [14]

Answer:

∠ 2 = 48°

Step-by-step explanation:

the 2 angles form a right angle = 90°

sum the 2 angles and equate to 90°

∠ 2 + 44° = 90° ( subtract 44° from both sides )

∠ 2 = 48°
