we know that the shaded side is 90 degrees and we are given 28 degrees

So we add 90+28 and we get 118

Since a triangle has 180 degrees, we subtract 180-118 to fins the missing angle measure

180-118=62

x=62

Your equation is 180=90+28+x

well it is a right triangle so you know the angle is 90

all angles in a triangle equal 180 degrees

so you make an equation

28+90+x=180

simplify

118+x=180

-118   -118

x=62 degrees

hope I was helpful

A roller coaster at XTRA Fun Rides goes into an underground tunnel during the first descent of the
gregori [183]

Answer:

y-intercept:  (0, 75) ⇒ y = 75

x-intercepts:  (3, 0) and (5, 0) ⇒ x = 3 and x = 5

vertex: (4, -5)

Step-by-step explanation:

Let the x-axis be the ground (when y = 0).  Therefore underground when y < 0 and overground when y > 0

The function is a quadratic:  f(x) = ax² + bx + c

If the coaster enters the tunnel three seconds after the first descent starts and stays in the tunnel for a total of 2 seconds, then y = 0 when x = 3 and x = 5

Also, when x = 1, y = 40

  • f(3) = 0
    ⇒ 9a + 3b + c = 0
  • f(5) = 0
    ⇒ 25a + 5b + c = 0
  • f(1) = 40
    ⇒ a + b + c = 40

Solve 2 equations simultaneously:

  • 9a + 3b + c = 0
  • 25a + 5b + c = 0
  • a + b + c = 40

⇒ a = 5  b = -40  c = 75

⇒ f(x) = 5x² - 40x + 75

<u>y-intercept</u>

when x = 0

⇒ f(0) = 5(0²) - 40(0) + 75 = 75

⇒ y-intercept = (0, 75)

<u>x-intercepts</u>

x = 3 and x = 5

<u>Vertex</u>

If the x-intercepts are when x = 3 and x = 5, then vertex is when x = 4

⇒ f(4) = 5(4²) - 40(4) + 75 = -5

⇒ vertex = (4, -5)

Your water bill consists of five parts: A base hookup fee of $32.50, a water fee of $0.03 per gallon of water, a sewer fee of $0
Taya2010 [7]

hi

You have to keep calm and to treat data as it come.  

<u>1 ) Start by constant fees :  </u>

hook up fees  is  32.50  and  trash collection fees are 35

so contant fees  :  32.50 +35 =  67.50  

2 )  Now we have to deal with variable fees which depend on how much water is used

water fees :  

0.03 per gallon, and we have  4 000 gallon, so  :  

0.03*4 000 = 120  

Sewer fees  :  

0.01  per gallon, and we have  4 000 gallon, so  :  

0.01  * 4000 = 40  

3 ) Total before taxation we have :  

67.50 +120 +40 =  227.5  

4)  Now we apply tax on the total before tax.

tax is  5 % , which mean you rise the "off tax " price by 5 percent.  

<u>To grow a number of  X % ,  you multiply by  1+  X/ 100 </u>

here  X = 5  so  the multiplicator is  :  1 + 5/100 = 1.05  

<u>So total of the bill is :   227.5 * 1.05 = 238.875  </u>

The water compagny is  probably going to round it up to 238.88
