Answer:
Step-by-step explanation:
A.)Priscilla made a mistake when applying the horizontal shift. That "x+2" indicates a horiz. shift to the LEFT, not to the right.
Answer:
Option A.
Step-by-step explanation:
Priscilla graphed function g(x), a transformation of the quadratic parent function f (x) = f ( x+2 ) - 1
(1) She graphed the vertical compression correctly
(2) Priscilla graphed the vertical shift of (-1) means 1 unit downwards on y-axis correctly.
(3) In the last she made a mistake because for f(x+2) the parent function should have been shifted left on x-axis by two units f (x) ⇒ f[ x- (-2)]
Therefore Option A will be the answer.

Suppose x is the total cost for the first purchase, cost of the bread = b and cost of the milk = m Then:- y = 5b + 2m y - 4.2 = 2b + 5m Subtract:- 4.2 = 3b - 3m b - m = 4.2 / 3 = 1.4 That is bread costs $1.40 more than the milk. (Answer). Its A
Answer:
26.3 rev/min
Step-by-step explanation:
The angular velocity (ω) is the linear velocity divided by the radius ( r= 80 feet)
ω = 220/80 = 2.75 rad/s
The angular velocity and the frequency are related by :
ω = 2π*f
2.75 = 6.28*f
f = 2.75/6.28
f = 0.438 rev/s * 60s/1min
f = 26.3 rev/min
The answer is 9. hope I helped
