First, you can notice that the angle of 130 degrees and the angle next to it make up a line. So, they should add up to 180 degrees. We do 180-130 to get 50. So that angle next to 130 is 50 degrees. The interior angles of a triangle should add up to 180 degrees so let’s do 180-50 to get 130. The angles are equal to each other so we can just do 130/2 and get 65 degrees. Lastly, y=65 degrees.

Answer:

-7x^3+8x^2+x-5

Step-by-step explanation:

We are simply adding the two functions:

f(x) + g(x) = (2x^2-5x^3+x-7) + (6x^2-2x^3+2) = 8x^2-7x^3+x-5 = -7x^3+8x^2+x-5

Solve the quadratic equation below x2−25=0

WARRIOR [948]

X= 12.5, this is because you need to add 25 to the other side of the equation to make 2x = 25 and then divide both sides by 2 to get x=12.5

Arrange the equations in the correct sequence to rewrite the formula for displacement, , to find a. In this formula, d is displa

valina [46]

Answer:

$a=2[d-V_0t]/t^2=2d/t^2-2v_0/t$

Explanation:

Since, you have not included the formula, I will work here with the formula for constant accelaration motion that relates the four variables: displacement (d), Vo (initial velocity), a (acceleration) and t (time).

1) displacement formula:

$d= V_0t+\frac{1}{2} at^2$

2) Subtract the term Vot from both sides:

$d-V_0t= \frac{1}{2} at^2$

3) Multiply both sides by 2:

$2d -2V_0t=at^2$

4) Divide both sides by t²

$2[d-V_0t]/t^2=a$

So, you have obtainded:

a = 2[d - Vo×t] / t²

Yet, you can arrange it in different ways. For example, you might separate into two terms:

$a = \frac{2d}{t^2} - \frac{2V_0}{t}$
