Answer:
Step-by-step explanation:
Given the expression
According to the law of logarithm;
loga + log b = log(ab) and log a - log b = log(a/b)
The given expression becomes;
The equation is y = -1/4x - 4.
Point Slope Form: y - y1 = m(x - x1)
Given: (-4,-2) and y = 2x + 5
When you are given a line that is perpendicular, flip the slope upside down and change it to it's opposite (negative to positive etc).
Slope: -1/2
Now plug that and the point into the formula for PS form.
y - (-2) = m(x - (-4))
y + 2 = -1/2(x + 4)
y + 2 = -1/2x - 2
- 2 - 2
---------------------------
y = -1/2x - 4
Answer:
r≥2.5
it can't be < because the green dot is filled in
r is larger than 2.5 because the arrow goes to the right
THe amplitude is half of the distance from the highest and lowest phase of the wave..
4-(-1)=5
0.5*5=2.5
amp=2.5 units
Formula for volume is:
width x length x height
5 x 7 x 20
5x7 = 35
35x20= 700
Answer is 700 cm^2
