Answer:

7.(1,0) and (-4,0)

8. (-3,0) and (-2,0)

Step-by-step explanation:

When the function is equal to zero, we are looking for the zeros, or the x intercepts

Where it crosses the x axis are 1 and -4

(1,0) and (-4,0)

8. When the function is equal to zero, we are looking for the zeros, or the x intercepts

Where it crosses the x axis are -3 and -2

(-3,0) and (-2,0)

Can someone PLEASE answer this question (picture above)

Answer:

11.89

Step-by-step explanation:

let x be the increases length

now (6.4+x)(4+x)(10.5+x) = 2*250

solving this we get x = 1.39

so the largest dimension is 10.5+ 1.39 = 11.89

Perform the operations and write the answer in simplest form 2 2/5 + 3 1/4

iragen [17]

Answer: 2 2/3

Step-by-step explanation:

we have to turn this into a improper fractions first (so its something like a bobble-head)

(2 2/5) 5 x 2 = 10 + 2 = 11/5

(3 1/4) 3 x 4 = 12 + 1 = 13/4

Then add those two.

11/5 + 13/4

11 + 13 = 24

5 + 4 = 9

so now its time to put it in simplest form 8/3

Now 8 divided by 3...BUT WAIT...3 can't go into 8

Now we turn it into a Mixed Number 2 2/3

Need help ASAP DUE IN A COUPLE MINUTES ?!!!!

Georgia [21]

Answer:

$\displaystyle {r}^{} = 6$

Step-by-step explanation:

remember that,

$\displaystyle V _{ \rm sphere} = \frac{4}{3} \pi {r}^{3}$

given that,

V=288π

thus substitute:

$\displaystyle \frac{4}{3} \pi {r}^{3} = 288\pi$

divide both sides by 4/3π:

$\displaystyle {r}^{3} = 216$

cubic root both sides:

$\displaystyle {r}^{} = 6$

and we are done!

Day Drive 270 miles and 6 hours how many miles do you drive in 13 hours

NikAS [45]

Answer:

The answer is

<h2>585 miles</h2>

Step-by-step explanation:

In order to solve this question we use ratio and proportion

From the question

Day Drive 270 miles in 6 hours

So in order to find the distance drove in 13 hours, we compare the distance drove in 6 hours to the distance drove in 13 hours and solve

That's

if in 6 hours Day drove 270 miles

Then in 13 hours the person will drive

$\frac{13 \times 270}{6} = \frac{3510}{6}$

We have the final answer as

<h3>585 miles</h3>

Hope this helps you
