Answer:

-44

Step-by-step explanation:

So you want to plug 2 in for t, so the equation should now look like:

2^{2} - 44 - 4

No all you have to do is solve

2^{2} = 4

4 - 44 = -40

-40 - 4 = -44

-44

Step-by-step explanation:

t=2, t² - 44 - 4

1. substitute in the value to the variable: 2² - 44 - 4

2. using PEMDAS, solve the equation: 2² - 44 - 4 = 4-44-4 = -40-4= -44

(evaluate the exponent, then subtract)

Given: circle k(O), ED diameter, m∠OEF=32°, m EF=(2x+10)°. Find: x
Snezhnost [94]

Answer:

The value of x is 53\°

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of arc DF

we know that

The inscribed angle measures half that of the arc comprising

so

m

we have

m

substitute

32\°=\frac{1}{2}(arc\ DF)\\ arc\ DF=64\°

step 2

Find the measure of x

we know that

arc\ DF+arc\ EF=180\° ---> is a semi circle

we have

arc\ DF=64\°\\ arc\ EF=(2x+10)\°

substitute

64\°+(2x+10)\°=180\°\\ 2x\°=180\°-74\°\\ 2x\°=106\°\\ x=53\°
