Answer:
Your answer is B) 3.6 cm.
Step-by-step explanation:
10 mm = 1 cm. To convert 36 mm to cm all you have to do is divide by 10.
36/10 = 3.6
So, 36 mm = 3.6 cm.
In the future, if you were to convert cm to mm, just multiply by 10.
Start by putting into improper fractions.
- 1 2/3 = - 5/3
- 2 1/5 = - 11/5
Now stack the fractions like this.

Here's the key part (or one of them). Cancel the minus signs. Since there are 2 of them they become a plus.

Now invert the 11/5. That means turn it upside down. Put the 5 in the numerator and 11 in the denominator. Multiply by it by the top fraction.

When you do this, you just multiply top by top and bottom by bottom
Answer:
-8x^2+26x-21
Step-by-step explanation:
(3-2x)(4x-7)
12x-8x^2-21+14x
-8x^2+12x+14x-21
-8x^2+26x-21
This is a parabola. 20 ft represents the height of the ball. Height is represented by the letter h. Thus you need to plug 20 into the equation for h and solve for t.
