Answer:
60 cm ( squared )
Step-by-step explanation:
you can find the area of the trapezoid ( by decomposing it into other shapes ) by separating two triangles, and using the formula to find the area of triangles, which is A= 1/2 ( b x h ) and add the answer to those together ( 16 cm squared and 4 cm squared ), and after that, you can find the area to the rectangle by multiplying the l x w, which is 10 x 4 ( after separating the triangles.). That equals 40, and when you add them all together ( 16 + 4 + 40 ) it equals 60 cm (squared).
Answer:
r = 17, two points are possible (-15, 14) and (-15, -16)
Step-by-step explanation:
Radius is a distance between the center and any point. Use the distance formula: r = sqrt( (8-(-7))^2 + (7-(-1))^2) = 17.
Now you can use distance formula to find the possible y coordinates of the points when x = -15:
17= sqrt( (-15 - (-7))^2 + (y-(-1))^2
289 = 8^2 + (y+1)^2
225 = (y+1)^2
from here you need to split into two possibilities:
1. y+1 = 15 then y = 14
2. y+1 = -15 then y = -16

I got the answer 390 no sure if it's true
The question also states that each brick weighs 4 lb and ask to find 1) the function and 2) the total load if the wheelbarrow carry 20 bricks.
1) Function: weight of the wheelbarrow + weight of the bricks
call x, the number of bricks
f(x) = 42 + 4x
2) total load with 20 bricks
f(20) = 42 + 4(20) = 42 + 80 = 122 lb
