Answer:
21.
Step-by-step explanation:
f(x) = 2x^2 - 3x + 7.
When x = -2,
f(-2) = 2(-2)^2 - 3(-2) + 7
= 2(4) - (-6) + 7
= 8 + 6 + 7
= 21.

Answer:
100 inches
Step-by-step explanation:
Given that the mans height is 71 inches. Height of lamp is 108 inches and distance between them is 52 inches. For Figure refer to attachment . The given figure both triangles are similar by AA similarity Condition. So we know that the corresponding parts of similar triangles are proportional .Let Distance between man a d its shadow be x .
<u>Using</u><u> </u><u>this </u><u>concept</u><u> </u><u>,</u><u> </u>
=> AM / PN = QA / QP
=> 108 / 71 = 52 + x / x
=> 1.52 x = 52 + x
=> 1.52 x - x = 52
=> 0.52 x = 52
=> x = 52/0.52
=> x = 100 in .
