Answer:
f(x)= 2ˣ
We have to find x when f(x) is 8
8=2ˣ
we can write 8 in exponential form as 2³
2³=2ˣ
here base is same (2) on both left and right side
comparing the powers we get
x=3
:)
Answer:
I made the assumption those were right triangles.
Step-by-step explanation:
I like your 30 there.
I found the length in orange by doing 55-30=25.
Now we can try to find the length in light purple by doing orange length plus the length you found which is 25+30=55.
So we can use a trig function to find .
I made another picture to focus our problem more.
Now if you look at the triangle we have here and refer to trig right triangle definitions, we can setup an equation form this.
The opposite side of the angle, whose measurement is degrees, is .
The adjacent side of the angle, whose measurement is degrees, is .
So I will use the tangent ratio.
Multiply both sides by 55:
Now it is handy dandy calculator punching in time:
Assuming it’s a equilateral triangle the answer is 8sqrt(3)
Height 12cm
Cut the triangle in half so it becomes a 30-60-90 triangle
So 12/sqrt(3)=x and the side you want is 2x so it is 24/sqrt(3) for each side but you need to make sure you simplify it to (24sqrt(3))/3 and then one more time to 8sqrt(3)
Answer:
A. A number that is divisible by 6 is also divisible by 2 and 3 because 2 and 3 are factors of 6.
Hope this helps~
