Given:
edge 1 = 3x - 4
edge 2 = x² - 1
edge 3 = 2x² - 15
perimeter if x = 4
edge 1 = 3(4) - 4 = 12 - 4 = 8
edge 2 = 4² - 1 = 16 - 1 = 15
edge 3 = 2(4²) - 15 = 2(16) - 15 = 32 - 15 = 17
Perimeter = 8 + 15 + 17 = 40 feet.
Answer:
0.9821
Step-by-step explanation:
Probability that a randomly selected value will be less than 2.1 deviations from the mean ; this means the Zscore = 2.1
Hence, using :
P(Z < 2.1) = 0.9821 (standard normal table
= 0.9821
Just multiply Base x Height and you'll get your answer
Answer:
See below
Step-by-step explanation:
<u>Given a polygon with vertices</u>
- A(-6, 5), B(-6, 2), C(-2, 2), D(-2, 6)
<u>Translation rule is</u>
<u>New coordinates are</u>
- A' = (-6 + 5, 5 - 4) = (-1, 1)
- B' = (-6 + 5, 2 - 4) = (-1, -2)
- C' = (-2 + 5, 2 - 4) = (3, -2)
- D' = (-2 + 5, 6 - 4) = (3, 2)
