x = 0.0002644

Step-by-step explanation:

\log _{8}3x + 5 = \log_{8}26\\

We want get the logs on the same side

\log _{8}3x-\log_{8}26=-5\\

When you subtract logs with the same base, the insides get divided

\log_{8}\frac{3x}{26} =-5

If \log_{8}x=2\\x = 8^2\\x = 64

We have to do the same here

\frac{3x}{26} =8^-^5\\\frac{3x}{26}=\frac{1}{8^5}\\\frac{3x}{26}=\frac{1}{32768}\\\\3x = \frac{26}{32768}\\x=\frac{26}{32768*3}\\x=\frac{13}{49152} = 0.0002644

The baseball coach is 70 inches tall. How tall is the child?
tankabanditka [31]

The child is <u>59.4 inches tall</u>, assuming the length from the coach's shoulder to his head cap is approximately 10 inches.

<h3>What is Heigth?</h3>

Height refers to the vertical distance between the top and bottom of something.

Height measures the length of some objects or persons vertically to determine whether it is high or low, according to some ascertained criteria.

<h3>Data and Calculations:</h3>

Baseball coach's height = 70 inches

Coach's shoulder to head = 10.6 inches

Height of the child standing slightly below the coach's shoulder = 59.4 inches (70 - 10.6)

Thus, the child standing slightly below the coach's shoulder is 59.4 inches tall.

Setler79 [48]

Step-by-step explanation:

Hey there!

According to the question, you need to find out the distance from your friend's house to school.

<em>Firstly figure out the coordinate of your school and school. Then use formula of distance.</em>

So, we find the coordinates as (7,7) and (5,0).

So, x 1 = 7 y1= 7

x 2 = 5 y2 = 0

~ Use distance formula.

d =  \sqrt{( {x2 - x1)}^{2}  + ( {y2 - y1)}^{2} }

~ Put all values.

d =  \sqrt{ {(5 - 7)}^{2}  + ( {0 - 7)}^{2} }

~ Simplify it.

d =  \sqrt{ {( - 2)}^{2}  +  {( - 7)}^{2} }

d =  \sqrt{4 + 49}

d =  \sqrt{53}

D= 7.280

Therefore, the distance between your friend's house and your school is 7.3 units.
