Answer:80

Step-by-step explanation:

Volume of a prism= Base × height

Base area= length×width (for a rectangle base prism)

Base=5×2=10cm2

Volume=Base×height

V=10×8=80cm3

Ray and Claudia are writing in journals. Ray has written 16 pages and he now writes 2 pages every day. Claudia has written only

balu736 [363]

Answer:

6 days

Step-by-step explanation:

Step one:

Given data

For Ray

He has 16 pages already

Now he is writing 2 pages per day

let x be the number of days

and y be the total number of pages writen

the linear function for the situation is given as

y=2x+16-------------1

For Claudia

He has 2 pages already

Now he is writing 4 pages per day

let x be the number of days

and y be the total number of pages writen

the linear function for the situation is given as

y=4x+2-------------2

Step two:

let us equate equation 1 and 2 to find x

2x+16=4x+2

collect like terms

2x-4x=2-16

-2x=-12

divide both sides by -2

x=12/2

x=6

Therefore it will take 6 days for them to have the same number of pages

Although you love to watch TV, you have made a goal to spend more time outdoors. You decide that you will spend 222 times as man

Diano4ka-milaya [45]

Answer:

the equation that should be required is 0 = 2t

Step-by-step explanation:

Let us assume the hours of television be t

And, for hours outdoor be o

As the hours outdoors would be twice the hours of television so the equation is

0 = 2t

Therefore the equation that should be required is 0 = 2t

The same is relevant

Need help finding equation

Elden [556K]

Answer:

Step-by-step explanation:

Based on the two graphs I see at the bottom of the photo, you're looking at a quadratic function. The answer you put in is a linear equation.

Quadratic functions follow the form $ax^2+bx+c$ , where a, b, and c can be either positive or negative constants.

The table says that the equation, when graphed, should start at the top, slide to the bottom, and then slide back up to the top. So a must be positive.

c has to be -8 since it's the y-intercept.

So far, our equation is $ax^2+bx-8$ . We'll need to plug in some points in order to work out what $a$ and $b$ are.

Let's use $(-2,5)$ as the first set of points, and $(4,14)$ as the second set.

$5=a(-2)^2+b(-2)-8\\14=a(4)^2+b(4)-8\\$

Now we have 2 equations with 2 unknowns. Solve for one variable:

$5=4a-2b-8\\13+2b=4a\\\frac{13+2b}{4}=a$

Now substitute that into the second equation:

$14=(\frac{13+2b}{4})(4^2)+4b-8\\14+8=(13+2b)(4)+4b\\22-52=8b+4b\\-30=12b\\-\frac{30}{12}=-\frac{10}{4}=-\frac{5}{2}=b$

Now substitute the result into the first equation.

$\frac{13+2(-\frac{5}{2})}{4}=a\\\\\frac{13-5}{4}=a\\\\\frac{8}{4}=a\\\\ 2=a$

Now substitute our values back into the original equation:

$y(x)=2x^2-\frac{5}{2}x-8$

Please let me know if this is correct.
