Answer:
4, -3
Step-by-step explanation:
The quadratic formula is .
When using the formula for both the negative and positive value of the sqrt, you will get:
x = 4, -3
The answer is 0 because when you plug in the 3 and the 8 into the equation and do order of operations you will get 0.
650 -136=514
514 divided by 25 = 20.56
So it would be 21
This will give you a little extra chairs but they have to be equal in each row
5000*0.03+0.05x=275
Solve for x
X=2500
The answer is b
The angle of depression made by the bird to the mouse is seen on the attached image. We can find the distance from the field mouse up to the bird's eye by getting the hypotenuse of the triangle formed. Using the CAH in Pythagorean Theorem, we will have:
cos ∅ = adjacent / hypotenuse
cos 65 = 30 / h
h = 70.98 ≈ 71 m ⇒
the answer is D
