Answer: 8.75
Step-by-step explanation:
575 divided by 3 equals 175. Divided by 20 equals 8.75. Probably rounds up to 9 but i dont know.
Answer:
d. 55 feet /sec^2
Step-by-step explanation:
Average acceleration is ...
a = ∆v/∆t = (116 ft/s -6 ft/s)/(2 s)
= 110/2 ft/s^2 = 55 ft/s^2
Answer:
Step-by-step explanation:
3. Use Cosine law to find the length of the unknown side (PR)
q² = p² + r² - 2prCos Q
q is the opposite side of ∠Q;
p is the opposite side of ∠P; p = 33
r is the opposite sides of ∠R ; r = 67
q² = 33² + 67² - 2* 33*67 Cos 19°
= 1089 + 4489 - 4422 * 0.95
= 1089 + 4489 - 4200.9
= 1377.1
q = √1377.1
q = 37.1
PR = 37.1
To find the angle use law of sin

Sin P = 0.3

P = 17.5°
∠R = 180 - (19 + 17.5)
= 143.5°
Answer:
(-1.5, 0) and (0, -6)
Step-by-step explanation:
Check the picture below
the triangles are similar, the angles are congruents then
so... just add them up, and divide by 2, or set them as rational
