7 = - (t-1)
7=-t-1
t=-1-7
Calculate the difference
t=-8 ( here’s your answer)
Answer:
9000
Step-by-step explanation:
4
largest:4/7×21000 = 12000
smallest: 1/7×21000. = 3000
12,000-3000 = 9000
The equation and steps are...
First, find the slope of the original equation. In this case, the slope is -8. You know that perpendicular lines have slopes that are negative reciprocals, so the negative reciprocal of -8 is 1/8.
Now, use this new slope and the given point to find the y-intercept:
y = mx + b
4 = (?)(2) + b
4 = ? + b
15/4 = b
Use the new slope and y-intercept to write the new linear equation:
Answer:
y = 1/8x + 15/4
Sorry if i'm wrong
seemed easy
The perimeter of a circle is given by:
P = 2 * π * r where r is the raduis.
Therefore the length of a semicircle is π * r
The radius is therefore
r = 10.28mm / π = 3.272mm
