A skateboard halfpipe is being designed for a competition. The halfpipe will be in the shape of a parabola and will be positione

levacccp [35]

Answer:

Option A , (0, 20); y equals one over eighty times x squared plus 20

Step-by-step explanation:

The equation of parabola is given by

(X-h)^2 = 4p(Y-k)^2

In this case h = 0

So we get

Y = X^2/4P +k

Focus point is (h, p+k) , p+k = 40

Hence h, k = (0,20)

P = 40-k = 20

Equation Y = X^2/80 +20

Hence, option A is correct

The statement below describes a situation in which opposite quantities combine to make zero: A cup with a hole in it loses 2 oun

Anna71 [15]

Answer:

False

Step-by-step explanation:

A cup with a hole in it loses 2 ounces of water in the first minute. This mathematically means

Add -2 (loses ⇒ means getting less)

Then the cup loses 2 ounces of water in the second minute. This mathematically means

Add -2 (loses ⇒ means getting less)

In total,

$(-2)+(-2)=-4\neq 0$

and means loses 4 ounces in two minutes.

Thus, the statement below does not describe a situation in which opposite quantities combine to make zero, so this statement is false

This is the problem Dan says 3/5 Is the same as 3.5. Is he correct? Explain

lesya692 [45]

Answer:

He is not correct

Explanation:

The first number is $\frac{3}{5}$

We can note that the numerator is less than the denominator. This means that the given fraction is less than 1

In decimal form, $\frac{3}{5}$ is equal to 0.6

The second number is 3.5

We can note that this number is greater than 1.

This means that the two numbers are not equal

Hope this helps :)
