Answer:

A. 4.5 ft

B. 4 ft

C. 1 ft

Step-by-step explanation:

If you pretend that h is replacing y and d is replacing x and you would graph the equation, then you would get a parabola that opens down.

You would need to find the vertex of the parabola. The ordered pairs would be (d, h) instead of the normal (x, y).

A. The maximum height will be the h value of the vertex

B. Let h = 0 and solve the equation for d. That will give you distance from the stump that the frog landed.

C. The distance from the log at the maximum height is the d value of the vertex

So, that is what is needed to be done.

Without me going thru all the work, the vertex is (1, 4.5) and the solutions to the equation when h = 0 are 4, -2 (discard -2 since a distance cannot be negative)

So the answer to A is 4.5 ft.

The answer to B is 4ft.

The answer to C is 1 ft.

Now, can you find the vertex on your own and can you solve the equation when h = 0? I hope so. OK?

Answer:

Cone is equal to 3, white ice cream is equal to 2, and the pink is equal to 1.

Step-by-step explanation:

Something times something times something is equal to 27, and 27=3x is equal to 3. The cone is equal to 3.

3+3=6, and since 10-6 =4, 4=2x, so the white ice cream is equal to 2.

3+3+3=9, and 2+2=4, 9+4=13, so 15-13=2, and 2=2x, so the pink ice cream is equal to 1.

Sorry if it was a little cofusing.

When a set of unequal amounts is redistributed equally, the value of each new amount represents the __________.?

balu736 [363]

The correct answer to this question is "unequally distributed amount"

When a set of unequal amounts is redistributed equally, the value of each new amount represents the unequally distributed amount. Come to think of, it is already unequal in the first place. Distributing it doesn't make it equal.

I conduct a statistical test of hypotheses and find that the null hypothesis is statistically significant (reject H0) at the 10%

e-lub [12.9K]

Answer:

Step-by-step explanation:

if statistical test is significant at xyz percentage of significant level then it will be right to say that test will be significant to all percentage that is above significant level but it is uncertain that test will be significant at all percentage that is below significant level. Therefore it is uncertain that test would be significant at 1% and 5% because they are lie below than significant level (10%)

If n-8=-3, what is 3n?

<em>Greetings from Brasil...</em>

Let's isolate N. For that we will pass the - 8 to the second member:

n - 8 = - 3

n = - 3 + 8

n = 5
