what are the coordinates of that center of a circle if the endpoints of its diameter are a(8,-4) and b(-3,2)?

1 answer:

8 0

You need to add 8 and -3 together to get 5 and divide 5 by 2 to get 2.5
That is the x coordinate
You then need to add 2 and -4 together to get -2 and divide by 2 to get -1
This is the y coordinate
(2.5,-1)

HELP MEH I can't figure this out. Please explain

vova2212 [387]

Answer:

x ≈ 33.0

Step-by-step explanation:

The third angle in the triangle is

180° - 70° - 76° = 180° - 146° = 34°

Using the Sine rule in the triangle

$\frac{x}{sin76}$ = $\frac{19}{sin34}$ ( cross- multiply )

x × sin34° = 19 × sin76° ( divide both sides by sin34° )

x = $\frac{19sin76}{sin34}$ ≈ 33.0 ( to the nearest tenth )

The function P(x)=(x+3)^2+2 write a new function after a translation of 2 units up.

IrinaVladis [17]

Answer:

(x+3)^2+4 or x^2+6x+13

Step-by-step explanation:

The number in the parenthesis means the translation from the original left or right. The second number (outside of the parenthesis, in this case 2), is the translation from the original up or down. So, if the question were shift the graph of this function two units down, then the second number would decrease by 2. However, because the equation is shift the graph up 2 units, then you would add 2 to the second number. Same thing with the number inside of the parenthesis.

A car salesperson works 40 hours per week at a job where he has two options for being paid. Option A is an hourly wage of $16.

mr_godi [17]

10%

since he works 40 hours per week and gets $16 an hour, that would be 16 * 40 which is 640, so that means he needs a commission rate of 10% as 10% of 6400 is 640.

hope this is helpful!
