Find the length x. pls help

Mathematics
1 answer:
scoray [572]2 years ago
4 0

Answer:

x = 6

Step-by-step explanation:

To find x we set up an  equation as so:

\frac{4.5}{x} =\frac{6}{8}

Then we solve by multiplying 4.5 by 8 and 6 by x

6x=36    Solve for x

\frac{6x}{6} =\frac{36}{6}    x = 6

To check our answer when we substitute x or 6 we divide to make sure both sides equal the same number

\frac{4.5}{6} =\frac{6}{8}    when divided both equals 0.75

kotykmax [81]

Answer:$270

Step-by-step explanation:

I=PRT

Interest=principal times rate times time

Principal=1500

Rate=9%=0.09

Time=2

I=1500 times 0.09 times 2

I=1500 times 0.18

I=270

Interest=270

Total is 1500+270=1770 total paid

Remark
This question likely should be done before the other one. What you are trying to do is give C a value. So you need to remember that C is always part of an indefinite integral.

y = \int (cos(x) + sin(x) ) \, dx = \int{cos(x) \,dx + \int sin(x) \,dx
y = sin(x)  -  cos(x) + C 
y(π) = sin(π) - cos(π) + C = 0
y(π) = 0  -(-1) + C = 0
y(π) = 1 + C = 0
C = - 1

y = sin(x) - cos(x) - 1  <<<<< Answer

Problem Two
Remember that y =  \int\ { \frac{1}{x} } \, dx = ln(|x|) + C
y( - e^3 ) = ln(|x|) + C = 0
y(-e^3) = ln(|-e^3|) + C = 0
y(-e^3) = 3 + C  = 0
3 + C = 0
C = - 3

y = ln(|x|) - 3  <<<< Answer
