Answer:
8.) $7325.98
9.) $8218.10
Step-by-step explanation:
Compounded Interest Rate Formula: A = P(1 + r/n)^nt
Simply plug in our known variables into the formula:
A = 6000(1 + 0.04/12)^60 = 7325.98
A = 5000(1 + 0.05/4)^40 = 8218.10
5. We need to subtract 20% from the selling price of 18 000 as that will give his cost price
20/100 X 18 000 = 3600
18 000 - 3600
= 14 400.
7) 20 527,5 Rs
If we are concern only with the velocity of the particle along the x-axis, then, this implies that the velocity along the y-axis is hypothetically = 0ms^-1
∴ v = (vx=0,vy)
vy = 0ms^-1
vy = (dr/dt)y = 0ms^-1
ry→ = (2ct^2 -dt^3)j
dr/dt = 4ct - 3dt^2
4ct - 3dt^2 = 0
4c = 3dt
t = 4c/3d
Answer:
13
Step-by-step explanation:
The slope of the regression shows the average increase in response variable due to unit increase in explanatory variable. The regression equation of structure y=a+bx has slope=b.
The given regression equation y^=85+13x shows that the slope in the given equation is b=13. The response variable is amount of natural gas is used and explanatory variable is outside temperature in this case.
So, we can say that on increase of every unit of degree day the amount of gas used increase by 13 cubic feet.
The time will it take the runners to cover 1/A mile
t= 5904.6 sec
<h3>What time will it take the runners to cover 1/A mile?</h3>
Joel takes 63 sec for 14-mile long track
speed of joel
Jason takes 57 \mathrm{sec} for 14 mi track
so Jason's speed is
therefore
if both start from the same spot in opposite direction then
where x is the distance covered by Joel
then
time required
