Answer:

The answer to your question is letter C.

Step-by-step explanation:

A. This option is wrong because that equation is of a horizontal parabola, an the graph shows a vertical parabola.

B. The same as letter A. This option is wrong because that equation is of a horizontal parabola, an the graph shows a vertical parabola.

C. This option is correct, is the equation of a vertical parabola and the negative indicates that it opens downward, as in the graph.

D. This option is incorrect because the equation is of a vertical parabola that opens upward.

The Commutative Property of Addition

Step-by-step explanation:

They have a common denominator of 12

21/12+6/12+20/12+4/12+3/12+6/12=60/12=5 cups

or you could group ingredients with the same denominators

7/4+1/4+1/2+1/2+5/3+1/3=

8/4+2/2+6/3=

2+1+2=5

The Commutative Property of Addition says the order of the numbers doesn’t change the outcome.

A triangular pyramid with a height of 9 inches has a volume of 63 cubic inches. If the height of the triangular base is 6 inches

Bond [772]

Option D: 21 in is the base length of the triangular base.

Explanation:

Given that a triangular pyramid with a height of 9 inches has a volume of 63 cubic inches.

The height of the triangular base is 6 inches.

We need to determine the base length of the triangular pyramid.

The base length of the triangular pyramid can be determined using the formula,

$Volume =\frac{1}{3} \times Bh$

Substituting $Volume=63$ and $Height=9$ in the above formula, we get,

$63 =\frac{1}{3} \times B(9)$

Simplifying the terms, we get,

$63 =3B$

Dividing both sides by 3, we have,

$21=B$

Thus, the base length of the triangular pyramid is 21 in

Hence, Option D is the correct answer.
