Answer:
Given: b = -2
h = 4
Parent function y = root x or y = √x
Using the following equation we can find out the equation of the graph:
Step-by-step explanation:
A) C + A = 630
B) 2C + 5A = 2,910 Multiplying A by -2
A) -2C -2A = -1,260 Then adding it to B
B) 2C + 5A = 2,910
3A = 1,650
A = 550
A) C + 550 = 630
Children's tickets = 80
Answer:
0.18 sec or 3.4 sec.
For second part, it will take 3.7 sec.
First part:
Set h(t) = 17and solve for t.
-16t²+ 58t + 7= 17
-16t² + 58t - 10 = 0
Solve this quadratic equation for t. You should get 2 positive solutions. The lower value is the time to reach 17 on the way up, and the higher value is the time to reach 17 again, on the way down.
Second part:
Set h(t) = 0 and solve the resulting quadratic equation for t. You should get a negative solution (which you can discard), and a positive solution. The latter is your answer.
Answer:
1/5 hour or 12 minutes
Step-by-step explanation:
We can use proportions to solve this problem. Put the distance over the time
5 km 1 km
----------- = ---------
1 hour x hours
Using cross products
5x = 1
Divide by 5
x = 1/5 hour
or if we take it to minutes
1/5 * 60 = 12 minutes
Answer:
60 lbs large and 25 lbs small box
Step-by-step explanation:
50 large and 50 small boxes = 50 * 85 = 4250
5150-4250 =900 lbs weigh of 15 big boxes,
1 big box= 900 divide 15 = 60 lbs
85-60= 25 lbs = 1 small box
