Answer:

Step-by-step explanation:

Okay this isn't to hard for problems like this, you just have to multiply 8p to the numbers in the presentation so let's do it

8p*-3p^2= -24p^3

8*-3=-24

p*p^2=p^3

combine them both and get:

ans: -24p^3

8p*6p=48p^2

8*6=48

p*p=p^2

combine them both and get:

ans: 48p^2

8p*-2=-16p

8*2=-16

-16*p=-16p

ans:-16p

Then combine everything and get:<u>-24p^3 + 48p^2 -16p</u>

Write the standard form of the equation of the circle with its center at (-5,0) and a radius of 8 what is the equation of the ci

Leto [7]

Answer:

$\large\boxed{(x+5)^2+y^2=64}$

Step-by-step explanation:

The standard form of an equation of a circle:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - center

r - radius

We have the center (-5, 0) and the radius r = 8. Substitute:

$(x-(-5))^2+(y-0)^2=8^2\\\\(x+5)^2+y^2=64$

I can't solve this equation pleas help!x^2+2x+8=0

tiny-mole [99]

$x^2+2x+8=0\\
x^2+2x+1+7=0\\
(x+1)^2=-7\\
x+1=-\sqrt{-7} \vee x+1=\sqrt{-7}\\
x=-1-\sqrt7 i \vee x=-1+\sqrt7 i$

A packed box that is being shipped will be weighed in order to calculate the correct postage needed. The total weight of a packe

ivolga24 [154]

Answer:

Step-by-step explanation:

Total Weight of the package = weight of product + weight of box

Weight of empty box =0.88lb

Total weight of the box is =7.24lb

Let Weight of product inside box=w

Let wet of empty box =y

Total weight = F

Then,

F=y+w

Since F=7.24lb. y=0.88

Then, w=F-y

w=7.24-0.88

w=6.36lb

The weight of the product is 6.36lb

The following two-way table describes student's after school activites. Find the probability that a randomly selected student is

stiv31 [10]

The probability that a randomly selected student is in music/drama is 25%

<h3>How to determine the probability?</h3>

From the table, we have the following values

Music/Drama = 7 + 13 + 5 = 25

Total = (20 + 20 + 25 + 7 + 13 + 5 + 3 + 2 + 5) = 100

The probability is then calculated as:
P = Music/Drama / Total

So, we have:

P = 25/100

Express as percentage

P = 25%

Hence, the probability that a randomly selected student is in music/drama is 25%
