Answer:
x=2±16i
Step-by-step explanation:
1.) Using the PEMDAS distribute the using the FOIL method
2.) Distribute the -16 to ()
3.) Add the -25 to the equation
=0
4.) Since this isn't factor-able, you must use the quadratic formula,
and distrubute the numbers
a=-16 b=64 and c=-89
5.) Simplify the radical by finding the factors of -18688 that has a perfect root as one of the factors (which is -256 and 73).
6.)Simplify the fraction
7.) Your two roots are:
{2}(+ or -)16i\sqrt{73}
Answer:
Where:
And we can find the intercept using this:
On this case the correct answer would be:
E. none of the above
Since the intercept has no association between the increase/decrease of the dependent variable respect to the independent variable
Step-by-step explanation:
Assuming the following options:
A. there is a positive correlation between X and Y
B. there is a negative correlation between X and Y
C. if X is increased, Y must also increase
D. if Y is increased, X must also increase
E. none of the above
If we want a model where m represent the lope and b the intercept
Where:
And we can find the intercept using this:
On this case the correct answer would be:
E. none of the above
Since the intercept has no association between the increase/decrease of the dependent variable respect to the independent variable
Answer:
105mm
Step-by-step explanation:
I took the quiz
Length = x
width = y
2x + 2y = 32
x - y = 4
x = 4 + y
2(4+y) + 2y = 32
8 + 2y + 2y = 32
4y = 24
y = 6 cm (width)
x = 4 + 6
x = 10 cm (length)
