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:
B
( temp starts at 70 and DECREASES 8 per HOUR )
Answer:
<h2>25 meters squared</h2>
Step-by-step explanation:
area of a triangle: a=1/2bh
a= (1/2)(5)(10)
a=25
Put both in parenthesis to help you. Then you subtract like terms. (-4b^2 - 7b^2)(6b+2b because it is double negative) (-9+5)
so your answer would be
-11b^2+8b-4
Answer:
15
Step-by-step explanation:
8j -k+14
We want to find the value when j = .25 and k=1
Substitute the values in
8(.25) -1 +14
2 -1+14
1+14
15
