Answer:
6
Step-by-step explanation:
hello :
the nth term is : Bn= B1×R^n-1
calculate B3 (when n=3) R= -1/3 B1 = 54
B3 =54×(-1/3)^(3-1)
B3 =54×(1/9)=6
Answer:
i think 7% but i could be wrong
Step-by-step explanation:
sorry if im wrong :(
(x, y) is the ordered pair or the point of the line. The given problem is an example of a linear graph and its ordered pair represents (amount, number of gallons).
(3.75, 1) is one of the ordered pairs of the graph since $3.75 is the amount that you paid in 1 gallon of gas.
Moreover, $12 is the amount that Berto paid for the gas, we will divide it to $3.75 per gallon in order to get the number of gallon that is put in his car.
Solution: $12 / $ 3.75 per gallon= 3.2 gallons.
Therefore, another ordered pair on the graph of the line relating number of gallons of gas is (12, 3.2) since $12 is the amount that you paid for 3.2 gallons of gas.
The volume formula of a cylinder is given as:
V = π r^2 h
So plugging in the value of the volume:
10 ft^3 = π r^2 h
<span>h = 10 / (π r^2) --->
eqtn 1</span>
The formula for the surface area of cylinder is:
s = 2 π r h + 2 π r^2
plugging in eqtn 1:
s = 2 π r [10 / (π r^2)] + 2 π r^2
<span>s = (20 / r) + 2 π r^2 (ANSWER)</span>
Answer:
so you have to find angles
