Answer:
106
Step-by-step explanation:
Substitute x = 3 into f(x) and evaluate , that is
f(3)
= 10(3)² + 6(3) - 2 = 10(9) + 18 - 2 = 90 + 18 - 2 = 106
Answer:
1250
Step-by-step explanation:
?/5000 = 25/100 5,000x25= 125,000 divided by 100= 1250.00= 1250
Answer:
<u>Answer</u><u>:</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>(</u><u>2</u><u>k</u><u> </u><u>-</u><u>pw</u><u>)</u><u>/</u><u>p</u>
Step-by-step explanation:

multiply 2 on both sides:

open the bracket:

subtract pw from both sides:

divide p on both sides:

4th quadrant is positive x (cos) and negative y (sin)
Use the Pythagorean Theorem to calculate the value of y (sin).
x² + y² = c²
5² + y² = 13²
25 + y² = 169
y² = 144
y = 12
Since the y-value is negative in the 4th quadrant, then y = -12
Answer:
d. 540 deg
Step-by-step explanation:
2 pi radians = 360 deg
(360 deg)/(2pi rad) = 1
3 pi * (360 deg)/(2 pi rad) = 3 * 180 deg = 540 deg
