Ten point seventy five to nearest tenth is 10.8
Answer:
400 meters
Step-by-step explanation:
Let X = unknown.
tan28 =X/750
0.5317= X/750
Cross multiply
0.5317×750= X
x = 398.775meters or 400( to the nearest whole number)
Answer:
-f(3x - 1) + 2 = -18x² + 12x + 1
Step-by-step explanation:
Step 1: Find f(3x - 1)
f(3x - 1) = 2(3x - 1)² - 1
f(3x - 1) = 2(9x² - 6x + 1) - 1
f(3x - 1) = 18x² - 12x + 2 - 1
f(3x - 1) = 18x² - 12x + 1
Step 2: Plug in f(3x - 1)
-(18x² - 12x + 1) + 2
Step 3: Evaluate
-18x² + 12x - 1 + 2
-f(3x - 1) + 2 = -18x² + 12x + 1
Answer:
35°
Step-by-step explanation:
Angles DCE and DAE are supplementary, so ...
∠DCE = 180° -∠DAE = 180° -145°
∠DCE = 35°
Question 1: The correct answer is Option 3: 20
