How many solutions does the equation (x-7)^2-27=37 have?
atroni [7]

Answer:

If we are solving for x it has<u> two answers</u> <u>   15,-1</u>

EXPLANATION:

first i take the root of both sides and then solve from there :

Step 1: Simplify both sides of the equation.

x2−14x+22=37

Step 2: Subtract 37 from both sides.

x2−14x+22−37=37−37

x2−14x−15=0

Step 3: Factor left side of equation.

(x+1)(x−15)=0

Step 4: Set factors equal to 0.

x+1=0 or x−15=0

x=−1 or x=15

HOPE THIS HELPS

x=−1 or x=15

Alexander measures a stack of textbooks to be 38.2 cm tall. If there are 10 textbooks in the stack, how tall is each textbook?
Hunter-Best [27]

Answer:

3.82 cm tall.

Step-by-step explanation:

Alexander measures a stack of textbooks to be 38.2 cm tall. If there are 10 textbooks in the stack, how tall is each textbook?

From the above question:

1 stack = 10 textbooks = 38.2 cm tall

Hence,

10 textbooks = 38.2 cm tall

1 textbook = x cm

Cross Multiply

10 x = 1 × 38.2

x = 38.2/10

x = 3.82 cm tall

Therefore, each textbook is 3.82 cm tall.

How much would $150 invested at 8% interest compounded monthly be worth after 13 years? Round your answer to the nearest cent. h
dedylja [7]
Using that equation, our P = 150, r = .08, t = 13, and n = 12 (because there are 12 months in a year).  Filling in accordingly, we have  A(t)=150(1+ \frac{.08}{12})^{(12)(13)}.  Simplifying a bit we have  A(t)=150(1+.00666666)^{156}.  Doing the addition inside the parenthesis and then raising that number to the 156th power, we have A(t)=150(2.819469238).  Multiply those and get A(t) = $422.92
