Answer:
Step-by-step explanation:
This is a right triangle problem. The reference angle is x, the side opposite the reference angle is 32, and the hypotenuse is 58. The trig ratio that relates the side opposite a reference angle to the hypotenuse is the sin. Filling in accordingly:
Because you are looking for a missing angle, you will use your 2nd button and then the sin button to see on your display:
Within the parenthesis enter the 32/58 and you'll get your angle measure. Make sure your calculator is in degree mode, not radian mode!!!
(4x+5)(-3x-1)=
-12x²-19x-5
So, you answers would be:
A. (-16x²+10x-3) + (4x²-29x-2)
D. (2x²-11x-9) - (14x²+8x-4)

Answer:
12/5 gallons/minute, or 2 2/5 gallons/minute
Step-by-step explanation:
Find the unit rate with time as the independent variable:
2 gallons
---------------- = 12 gallons / 5 minutes = 12/5 gallons/minute
5/6 minute
The formula of a slope:
We have the points (-6, -1) and (-6, 4).
Substitute:
Dividing by 0 is not possible, therefore the slope is undefined.
<em>It's a vertical line x = -6</em>.
Answer:
<h2><u><em>
x = 25</em></u></h2>
Step-by-step explanation:
What is the solution to this equation?
6 * (x - 5) = 4x + 20
6x - 30 = 4x + 20
2x = 20 + 30
2x = 50
x = 50 : 2
x = 25
-------------------
check
6 * ( 25 - 5) = 4 * 25 + 20
6 * 20 = 100 + 20
120 = 120
the answer is good
