G(x) = f(2x) ; g(-2)
f (2 *-2)
g(x) = - 4f
g(x) = f(2x) ; g(-1)
f ( 2 * -1)
g(x) = - 2f
Q1) If 5 miles = 40 minutes.
Then, 5 * 3 = 15, and 40 * 3 = 120
In other words, it doesn't vary/differ because in order to get 15 miles in total you need one exact number, and since it's going by 5's and 40's you can just assume that 5 * 3 = 15 and 40 * 3 = 120 since 4 * 3 = 12.
Q2) Yes, of course the number of toppings varies because if you add more certain toppings it'd be added to your total, and customers can add more if they'd like. They don't need to do 4 specific toppings, it is up to them.
Answer:
first tower needs 4
second needs 3
third needs 2
and the fourth needs 1
Total needed triangles for all is 10
Step-by-step explanation:
total time, t = 4hours
1st speed, a = 6 mph
2nd speed, b = 15mph
total distance covered, d = 30miles
time spent at 6mph, x
time at 15mph, y
total time, t = x + y
=》4 = x +y...eqn 1
total dist, d = ax + by
=》30 = 6x + 15y...eqn 2
subst for y (= 4 -x) in eqn 2
30 = 6x + 15(4-x)
= 》 9x = 30
x = 3 1/3 = 3 hrs 20mins
y = 4 - 3 1/3 = 2/3 = 40mins
Answer:
length of rectangle CBED
= BC = 60 feet
width of rectangle CBED
= BE
BE
= 66 – (AB + EH)
BE
= 66 – (11 + 30) (EH = NI = 30)
= 25 feet
area of rectangle CBDE
= length × width
= 60 × 25
= 1,500 square feet
