<em><u>The equation to the rate of increase of the radius in terms of the radius is:</u></em>
<em><u>Solution:</u></em>
<em><u>The rate of increase (R) of the radius (r) in meters per second is inversely proportional to the radius</u></em>
Therefore,
<em><u>The radius is increasing at 1400 meters per second when the radius is 10 meters</u></em>
r = 10 m
R = 1400 meter per second
<em><u>Substitute in eqn 1</u></em>
<em><u>Substitute k = 14000 in eqn 1</u></em>
Thus the equation is found
Answer:
68.5 mph
Step-by-step explanation:
191.8 ÷ 2.8 = 68.5
Assuming the pilcrow is supposed to represent pi:
100
Answer:
The answer to all of those questions would be x=-1.8
Step-by-step explanation:
7x(x + 1.8) = 0 - Distribute through the Parenthesis -
7x^2 + 12.6x = 0
x(7x + 12.6) = 0
x = 0
7x + 12.6 = 0
7x = -12.6
x = -12.6/7
x = -1.8
so x = 0 or x = -1.8
Answer:17
Step-by-step explanation: Multiply Steve’s hourly wage ($7.40) by the hours he worked in a week (16 Hours) that would give you your weekly earnings which would be (7.40x16=$118.40) Then subtract what he saved in the bank from your total (118.40-105=$13.40) then you would divide $13.40 (his leftover money) by $0.75 to find the total number of carnival rides he could ride (13.40/0.75=17.86 rides and because he cannot ride 17 and 86 hundredths of a ride he would be able to ride 17 carnival rides.
