Answer:

a=4

Step-by-step explanation:

60=a(0+5)(0+3)

We can simplify this equation

60 = a (5) (3)

60 = a(15)

Divide each side by 15

60/15 = 15a/15

4 =a

A rectangular prism has a length of 5 1/8 feet, a width of 7 1/2 feet, and a height of 2 feet. What is the volume of the prism?
maksim [4K]

For this case we have that by definition, the volume of a rectangular prism is given by:

V = A_ {b} * h

Where:

A_ {b}: It is the area of the base

h: It's the height

According to the data we have:

length = 5 \frac {1} {8} = \frac {8 * 5 + 1} {8} = \frac {41} {8}

width = 7 \frac {1} {2} = \frac {2 * 7 + 1} {2} = \frac {15} {2}

Then:

A_ {b} = \frac {41} {8} * \frac {15} {2} = \frac {615} {16}

Thus, the volume is:

V = \frac {615} {16} * 2 = \frac {1230} {16} = 76.875

Answer:

76.875 \ ft ^ 3

\\ \rm\Rrightarrow \dfrac{x}{2}=3

\\ \rm\Rrightarrow x=2(3)

\\ \rm\Rrightarrow x=6

And

\\ \rm\Rrightarrow \dfrac{y}{2}+1=3

\\ \rm\Rrightarrow \dfrac{y}{2}=3-1=2

\\ \rm\Rrightarrow y=2(2)

\\ \rm\Rrightarrow y=4

A parabola has a vertex at (-2,6) and roots at 7 and m. Find the value of m
Archy [21]

Answer:

So m= - 11

Step-by-step explanation:

* THe vertex is (-2,6), then the equation is y = a(x+2)^2 +6, a is to find out.

* A root is 7 means x=7 and y=0, then :

0 = a(7+2)^2 +6

0=81a+6 or a= -6/81  = -2/27.

* We have the equation: y= -2/27 (x+2)^2 +6=-2/27 [ (x+2)^2-81]

y= -2/27 (x-7)( x+11).

So m= - 11

Hope that you understand.
