F(g)=sqrt(7x+b)
f(g(4))=sqrt(7*4+b)=6
sqrt(28+b)=6
28+b=36
b=36-28
b=8 which is A
Step-by-step explanation:
Count the number of times you have to move the decimal point to the right until it is to the right of the 1st nonzero number.
a) You have to move the decimal point 11 times until it gets to the right of the 1st nonzero number, which is 7. You then rewrite this number as

The exponent of 10 is a negative number because you moved the decimal point to the right.
b) Similarly, you have to move the point 9 times to the right so the answer is

Answer:
To calculate the simple interest, we say
S.I = (PxRxT)/100
Where P = the principal amount
R= rate in terms of %
And T= time.
Now P= $100 000
R= 8%
T= 3 years
S.I= (100,000 x8 x3)/100
=$2 400 000/100
= $24, 000
So the interest is 24000
Total amount he will be having = 100000 + 24 000
The total money he will be having in 3 years time = $124 000
Step-by-step explanation:
Answer:number of rows =10
number of places in row = 17
Step-by-step explanation:
number of rows =N
number of places in row = N+7
N(N+7)=170
N^2+7n-170=0
(N+17)(N-10)=0
N1=-17
N2=10
We can`t take negative value for quantity of smth so we throw N1 away
From that number of rows =10
number of places in row = 10+7=17
