Answer:
number of kilometers travelled by cavalier-86.4
he used 6litres for the journey. take number of kilometers divide by number of litres
86.4/6=14.4
Given the function f(x)=x^2+5x+5 , to get the zeros we solve using quadratic formula;
x=[-b(+or-) sqrt(b^2-4ac)]/(2a)
from our function;
a=1,b=5, c=5
thus,
x=[-5(+or-)sqrt(5^2-4*1*5)]/(2*1)
x=[-5(+or-)sqrt(25-20)]/2
x=[-5+/-sqrt(5)/2
The answer is option C
Answer:
1.75 %
Step-by-step explanation:
The formula for the future value (FV) of an investment is
FV =PV(1 + r/n)^nt
If the interest is calculated once a year, n = 1, and the formula reduces to
FV = PV(1 +r)^t
5550 = 5000(1 + r)⁶ Divide both sides by 5000
1.110 = (1+r)^6 Take the sixth root of each side
1 + r = 1.0175 Subtract 1 from each side
r = 0.0175 Convert to percent
r = 1.75 %
The interest rate is 1.75 %.
-8 You just divide because the quotient is the answer to a division problem
