Answer:
a) 18
b) 10
c) x^2 - 4x + 5
d) 4x^2 + 2
Step-by-step explanation:
f(x) = 4x - 2
g(x) = x^2 + 1
a) f(5) = 4(5) - 2 = 20 - 2 = 18.
b) g(-3) = (-3)^2 + 1 = 9 + 1 = 10.
c) g(x - 2)...
g(x - 2) = (x - 2)^2 + 1 = x^2 - 2x - 2x + 4 + 1 = x^2 - 4x + 5.
d) f(g(x)) = f(x^2 + 1) = 4(x^2 + 1) - 2 = 4x^2 + 4 - 2 = 4x^2 + 2.
Hope this helps!
Answer:
205 miles per hour.
Step-by-step explanation:
1 mile = 5280 feet so:
300 ft / second = 300/ 5280 miles/second.
There are 3600 seconds in an hour so
this converts to 300 * 3600 / 5280 miles per hour
= 204.55 miles per hour.
Hey! there are many ways to solve this question, but here are two!
ONE: since Dora bought 48 cupcakes at $0.55 each (which is SO CHEAP i want these cupcakes :), the total amount she spent is 48*0.55, which is $26.40. the number of vanilla cupcakes are 3/8 of the number of total cupcakes, so the cost would be 3/8 of the total cost, or 3/8*26.40
TWO: since the vanilla cupcakes make up 3/8 of all the cupcakes, that means that there are 18 vanilla cupcakes (48*3/8). each cupcake costs $0.55, so to find the cost of 18 cupcakes, multiply 18 by 0.55
