Answer:
O There is a change in the period of the function
Step-by-step explanation:
O There is a change in the period of the function; The period of sin x is 8 times longer than the period of sin 8x.
Answer:since the plane desends 1,300 feet per minute it would desend 19,500 feet afetr 15 minutes (1,300 × 15 = 19,500) subtract this from the planes's initial altitude 32,000 and the new altitude will be 12,500. (32,000−19,500=122,500
Step-by-step explanation:i did that up there
Answer:
a) PR = 17 cm, b) QR = 6 cm
Step-by-step explanation:
∠Q=90, so PQ and QR are legs, and PR is hypotenuse.
Pythagorean theorem PQ² + QR² = PR²
a) PQ² + QR² = PR²
8² + 15² = PR²
PR² = 289
PR = 17 cm
b) PQ² + QR² = PR²
8² + QR² = 10²
64 + QR² = 100
QR² = 36
QR = 6 cm
Answer:
f(x) = 8x + 15
f(-7)=8*(-7)+15=-56+15=-41
