Line segment FE is equals to Line segment BA or FE=BA.

B =  (2,4) A = (0,2) 

First we have to subtract the x and y coordinates. 

x = |2 - 0|
x = 2

y = |4-2|
y = 2

Then, we are going to use the Pythagorean Theorem a^2<span> + b^</span>2<span> = c^</span><span>2.

2^2 + 2^2 = 8

Get the square root of 8. The answer will be 2.83. Rounded off to the nearest tenth, the answer will be 2.80

I hope this helped you.

The answer is A. 2.8. Explained: I used the distance formula (or the top part of Pythagorean theorem) of d=square root of (x2-x1)+(y2-y1). Using points A (0,2) as (x1,y1) and point B (2,4) as (x2,y2) to put inside the distance formula. d=square root of (2-0)^2+(4-2)^2= square root of (2)^2+(2)^2= square root of (4+4)= square root of 8 which equals 2.8. Since triangle ABC is congruent to triangle EFD then since side AB equals 2.8 then side FE equals 2.8.

Answer:

7. y

=

−

1

/2

x  +  4

8.  y= (0,4)

Step-by-step explanation:

7. the slope is -1/2 and the y intercept is 4

8. so basically, the y intercept is when y is zero, which makes this one (0,4)

What value of c makes the polynomial below a perfect square?
malfutka [58]

Answer:

B

Step-by-step explanation:

x² + 9x

to complete the square

add ( half the coefficient of the x- term )² to x² + 9x

= x² + 2(\frac{9}{2} )x + (\frac{9}{2} )²

= x² + 9x + \frac{81}{4} ← the value of c

= (x + \frac{9}{2} )² ← a perfect square

The population of a town can be modeled by P= 22,000 + 125t, where P represents the population and the t represents the number o
nlexa [21]
Given that the population can be modeled by P=22000+125t, to get the number of years after which the population will be 26000, we proceed as follows:
P=26000
substituting this in the model we get:
26000=22000+125t
solving for t we get:
t=4000/125
t=32
therefore t=32 years
This means it will take 32 years for the population to be 32 years. Thus the year in the year 2032
