It is A. Because the point a would be on the -1 and the b would be on the -7 and the c would be on the -4
The answer is 8.71.
In order to find the value of any logarithmic function, you can raise the base (10 by default, unless stated otherwise) to the answer (.94) to get the number (x).
So, 0.94 = log x is basically saying 10^.94 = x. And when you raise 10 to the .94 power, you get 8.71.
My math teacher said anything to the power of zero is 1
Answer:
x=20°
2.
x=27°
Step-by-step explanation:
sin(x+20)=cos (2x+10)
=sin (90-(2x+10))
so x+20=90-(2x+10)
x+20+2x+10=90
3x=90-30
3x=60
x=60/3=20
2.
2x+14+x-5=90
3x+9=90
3x=90-9=81
x=81/3=27
