Answer:
missing value b is 14
Step-by-step explanation:
We have been given the modulus of a complex number which is

Here on comparing the given complex number with general a+bi we get:
a=48 and b=b
On substituting the values in the formula for modulus we get:






Therefore, missing value b is 14
Answer:
x = 9
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
(24+3) * 3 = x^2
27*3 = x^2
81 = x^2
Take the square root of each side
sqrt(81) = sqrt(x^2)
9 =x
Answer:
My best Gues is x=0 and x=6
Step-by-step explanation:
Because The zeroes of a function is where the line is equal to fx=0 which means it is where the line intercepts with the x axis. And the the line is on the x- axis touching 0 and it isn’t touching any negative number so it would have to be positive and would be 6.
Answer:
19.206
Step-by-step explanation:
First you need to find out 10% of 18.
You can do that by 18/100 which is .18.
Then multiply that by 10 which is 1.8 (10% of 18)
His hourly rate decreased by 3% AFTER his raise so you would find 3% of 19.8 and not 18.
You do the same process and divide 19.8/100
Then multiply this by 3 and you can get 0.594
That is how much his raise decreased by so you would subtract it from 19.8
19.8 - 0.594 = 19.206 (Round if needed)
Hope this helps
