Answer:
y = -9x-11
Step-by-step explanation:
The slope is -9 and a point is (-1,-2)
We can use point slope form
y-y1 = m(x-x1)
y--2 = -9(x--1)
y+2 = -9(x+1)
Distribute
y+2 = -9x-9
Subtract 2 from each side
y+2-2 = -9x-9-2
y = -9x-11
This is in slope intercept form (y=mx+b)
C. Multiply both sides by 9/5.
C = 5/9(F – 32)
We want to isolate F, which means we need to get F alone.
The quantity in the parentheses is multiplied by 5/9. We need to do the opposite, or multiply by the reciprocal to isolate the parentheses
9/5 C = 9/5* 5/9(F – 32)
9/5 C = F-32
This is the first step in isolating, or solving, for F
Answer:
yes it's wy =zy you may write it
Answer: 6.8829172362
Explanation:
sin35=e/12
Multiply 12 on each side
12sin35=e
A typical windmill has three blades. We can envision these blades in a circle, which a circle = 360 degrees. We want to divide up the angles of the blades so they are even or makes up 360 degrees. We have three blades so we have 3 angles to divide by 360 degrees. So, 360 / 3 = 120 degrees. Now that we know the angle of the blades, we can use the Law of Cos to solve the distance between the blade tip.
Law of Cos
We know
a = 20
b = 20
A = Angle = 120
We need to solve for c
Take the square root of each side of the =
Input the values we know into the formula and solve for c:
We now have our answer, which is 34.64 and that is C.
