Answer:
f(x) = 30(0.7746)^x
Step-by-step explanation:
30 (y)^0 = 30
30(y)^2 = 18 We need to find the value of y.
y^2 = 18/30 = 0.6
y = sqrt0.6 = 0.7746
so the exponential function is 30(0.7746)^x
Answer:
x ≈ 18.7
Step-by-step explanation:
This is a big equation, so let's break it down a bit.
Let's start by isolating the radical which is x.
So subtract 4 from both sides :
Now multiply both sides by 2 to get rid of the fraction :
Now divide both sides by 3 to get rid of the number out of the poly root :
Now take both sides of the equation to the power of 4 :
And lastly, solve :
which is rounded up to ≈
Answer:
≈ 11.4 m
Step-by-step explanation:
The diagonal splits the rectangle into 2 right triangles , with legs 7 and 9 and the diagonal the hypotenuse.
Using Pythagoras' identity with h as the diagonal, then
h² = 7² + 9² = 49 + 81 = 130 ( take the square root of both sides )
h = ≈ 11.4 m ( to the nearest tenth )
F(x)=-4(8)-5=
F(x)=-32-5=
F(x)=-37
Answer:
You caluculate the value of the segment then multiply it by 1/4. After that you move the compass to match the radius of the segment
Step-by-step explanation:
Sorry if that didnt make sense
