Answer:
Compound interest = Rs 1,575 (Approx.)
Step-by-step explanation:
Given:
Amount invested = R.s 6,500
Rate of interest = 7.5% per annum
Number of year = 3 year
Find:
Amount of compound interest
Computation:
Compound interest = P[(1+r)ⁿ - 1]
Compound interest = 6500[(1+7.5%)³ - 1]
Compound interest = 6500[(1+0.075)³ - 1]
Compound interest = 6500[(1.075)³ - 1]
Compound interest = 6500[1.2423 - 1]
Compound interest = 6500[0.2423]
Compound interest = 1574.95
Compound interest = Rs 1,575 (Approx.)
The idea is to pair up the terms, factor each sub-group, and then pull out the overall GCF to fully factor.
x^3+5x^2-6x-30
(x^3+5x^2)+(-6x-30)
x^2(x+5)+(-6x-30)
x^2(x+5)-6(x+5)
(x^2-6)(x+5)
-------------
Answer: (x^2-6)(x+5)
8*(n+6)=80
distribute
8n+48 = 80
subtract 48 from each side
8n = 32
divide by 8
n=4
The equation is : C=250t +125 where C is the cost and t represent the number of tickets purchased.
Step-by-step explanation:
Let the cost of premium seat ticket be C
Let the number of tickets a fan buys to be t
Then, presenting the information as ordered pairs of coordinates (x,y) will be;
Fan 1, (3,875)
Fan 2, (8,2125)
Plot the ordered pairs as coordinates on a graph tool, find the slope of the linear graph and equation in slope intercept form as;
m=Δy/Δx
m=2125-875/8-3
m=1250/5
m=250
Equation of the graph,
Δy/Δx=250
y-875/x-3 =250
y-875=250(x-3)
y-875=250x-750
y=250x-750+875
y=250x+125
C=250t +125 where C is the cost and t represent the number of tickets purchased
