A1 = (h (a + b)) / 2
A1 = (21 (17 + 32)) / 2
A1 = (21 x 49) / 2
A1 = 1,029 / 2
A1 = 514.5 mm²
[2]
A2 = (b x h) / 2
A2 = (11 x 9) / 2
A2 = 99 / 2
A2 = 49.5 mm²
[3]
The area of the shaded region =
A1 - A2 =
514.5 mm² - 49.5 mm² =
465 mm²
The answer is 465 mm².
Answer: 12.69 miles approx
Step-by-step explanation:
let x represent the number of miles traveled
1.75 + 0.65x = 10
0.65x = 8.25
x = 12.69 miles approx
Answer:
.
Step-by-step explanation:
A point of the form
belongs to the graph of this function,
, if and only if the equation of this function holds after substituting in
and
.
The question states that the point
belongs to the graph of this function. Thus, the equation of this function,
, should hold after substituting in
and
:
.
