Please answer this question! Easy, just not for me! Will give brainliest. :)
Mila [183]

Answer:

20.3 cm. to the nearest tenth.

Step-by-step explanation:

Using the Pythagoras Theorem:

CR^2 = CS^2 + SR^2

=  6^2 + 13^2

= 205

CR = √205 cm.

UR = CR (because they are both radii of the circle).

So UR = √205

and SU =6 + √205

= 20.3 cm to the nearest tenth.

Question: Find the vertex.<br><br> Equation: y = -x^2-6x+15<br><br> ([Put Number],[Put Number])
Artyom0805 [142]

Answer:

y = (x - 3)² + 6

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

Using the method of completing the square

y = x² - 6x + 15

add/subtract ( half the coefficient of the x- term )² to x² - 6x

y = x² + 2(- 3)x + 9 - 9 + 15

y = (x - 3)² - 9 + 15

y = (x - 3)² + 6 ← in vertex form

Billy’s employer pays for 65% of his annual health insurance premium. Billy has the rest deducted in equal amounts from his payc
Alenkasestr [34]

Answer:

4712.54

Step-by-step explanation:

His total annual premium 4712.54 . Billy received the deducted by $105.73 paycheck, twice a month throughout the year, so he received 24 deducted paychecks in a year.  The sum of all the deducted $105.73 amount throughout the year will be the 35% of Billy's total annual health insurance premium.

To get the amount his employer contribute towards his health insurance on an annual basis, we will have to multiply the sum deducted by twice a month throughout the year in which he received deducted paychecks.    

105.73 * 24  = 2537.52

The next step is to divide our answer with 35% of Billy's total annual health insurance premium.  

x = 2537.52/.35

x = 7250.06

7250.06 * 0.65 = 4712.54
