Let the width = x
      the length = x+7 
 => Area equation = length x width = x(x+7) = x^2 +7x = 78
=> x^2+7x -78 = 0
=> (x-6)(x+13)=0
=> x=6 or x=-13(no)
 => the width = 6 m
=> the length = 6+7= 13 m

Can someone help me answer a few of these? Thank you! :)
sesenic [268]
I’m going to try to answer these to the best of my ability.

1. Plane D
2. Plane C
3. AB
4. No
5. I don’t believe so because it doesn’t look like C is on the same plane as a AB and D.
6. I think so, yes! Collinear means that they are on the same line, and it looks like if you put a line between those two to connect them, they would connect perfectly!
7. B possibly? Because it looks like B, C, and D are all collinear and that they would pass through a straight line. A doesn’t look like it’s collinear with the rest of them.
8. No
9. Yes
10. Yes

I’m sorry if any of those are wrong, but I did make sure to try and put some explanations for some of them so you saw why I gave the answer that I gave! I hope that helped and like I said, I’m sorry if any of them are wrong, I tried my best!

If $500 is deposited in a savings account providing an annual interest rate 5.6% compounded quarterly, how long will it take for
Sidana [21]

Answer:it will take 5 years

Step-by-step explanation:

Initial amount deposited into the account is $500 This means that the principal is

P = 500

It was compounded quarterly. This means that it was compounded 4 times in a year. So

n = 1

The rate at which the principal was compounded is 5.6%. So

r = 5.6/100 = 0.056

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of t years. A is already given as $750

Therefore,

750 = 500 (1+0.056/4)^4×t

750 = 500 (1+0.014)^4t

750 = 500 (1.014)^4t

(1.014)^4t = 750/500 = 1.5

Take root 1/4 of both sides

(1.014)^4t ×1/4 = 1.5^1/4

(1.014)^t = 1.107

t = 5 years

Consider the following game: Roll a fair 6-sided die. You win if the result is greater than 4; otherwise, you lose. To play, you
dalvyx [7]

Answer:

-$1.33 or lose $1.33

Step-by-step explanation:

In this game, there are two possible outcomes.

- There is a 2 in 6 chance (rolling a 5 or a 6) that you win $8.

- There is a 4 in 6 chance (rolling a 1, 2, 3 or a 4) that you win nothing.

Note that for any outcome, you start off paying $4 to play.

The expected value of this game is:

E(X) =\frac{2}{6} *\$8+\frac{4}{6}*\$0-\$4\\E(X) = -\$1.33

You are expected to lose $1.33 per play.
