Answer:
Step-by-step explanation:
x²+10x+21=0
x²+10x+(10/2)²-(10/2)²+21=0
x²+10x+25-25+21=0
(x+5)²-4=0
(x+5)²=4
(x+y)²=(x+y)(x+y)=x(x+y)+y(x+y)=x²+xy+xy+y²=x²+2xy+y²
(x+y)²=x²+2xy+y²
coefficient of x=2y
y²=[(coefficient of x)/2]²=(2y/2)²=y²
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.)
Answer:
108°
Step-by-step explanation:
hii!
lmn would be equal to 85 plus 23.
this is because those angles both make up the big angle lmn, so the answer is 108 degrees.
hope this helped you :)
Answer:
P(t) = 9800(1.06)^t
P(8) = 15620
Step-by-step explanation:
For growth the equation is
y = ab^x where a is the initial value, b = 1 plus the growth percentage, and x is the number of years
P(t) = 9800 (1+.06) ^t
P(t) = 9800(1.06)^t
from 2000 to 2008 is 8 years
P(8) = 9800(1.06)^8
15619.71113040224768
We can only have whole foxes
P(8) = 15620
