Answer:
Step-by-step explanation:
Use your calculator
first times the 9 five times (9x9x9x9x9) then time it by the 177147.
then put that value in the
Since we are to complete the square, therefore I believe
the correct given should be:
x ^ 2 – 11 x
Take note of the symbol ^ which denotes that 2 is an exponent
of x.
The general form of a binomial equation is in the form of:
a x^2 + b x + c
Where in this case:
a = 1
b = -11
c = unknown
To complete the square, we have to find for the value of
c. This is calculated using the formula:
c = (b / 2) ^ 2
c = (-11 / 2) ^ 2
c = 30.25
Therefore the complete equation is:

Answer: 32000
Step-by-step explanation:
12000 divided by 3 =4000
4000 x 8 =32000
I guess C is the point where the flagpole touches the ground. If so:
ADC is a an isosceles right triangle. (ACD = 90, ADC = 45, then DAC=45).
So DC = AC = 5√3. Now let's consider the right triangle BCD:
ADC = 30, tan 30 = BC/DC:
tan 30 = BC/5√3, or tan30 = √3/3 → √3/3 = BC/5√3 and
BC =5. But AB = AC - BC
AB = 5√3 - 5
AB =5(√3 - 1) or AB = 3.66
