Answer:
<h3>5</h3>
Step-by-step explanation:
Given the expression
2a^3−10ab^2+3a^3−ab^2−7
We are to find the coefficient of a^3
First is to collect the like terms;
2a^3−10ab^2+3a^3−ab^2−7
= 2a^3+3a^3−10ab^2−ab^2−7
= 5a^3-11ab^2-7
From the resulting equation, you can see that the coefficient of the term having a^3 is 5
To determine the time it takes for the penny to reach the ground, we use the relation of height and time given above. We do as follows:
<span>
0 =−4.9t^2+(0)t+150
t = sqrt( 150/4.9)
t = 5.53 s
Hope this answers the question. Have a nice day.</span>
Divide both sides by 7.
n must be less than or equal to 3. n can be 3 or any number under 3.
For example, n can be 1, 2, 3.
Answer:
x=21.8
Step-by-step explanation:
The angles are complementary, and add to 90 degrees. We know this because of the little square in the corner.
x+68.2=90
Solve for x by isolating it. To do this , subtract 68.2 from both sides
x+68.2-68.2=90-68.2
x=21.8
