An object is thrown off a 256-foot-tall building, and the distance of the object from the ground is measured every second. The f

unction that models the height, h, of the object after t seconds is h(t) = –16t2 + 96t + 256. Determine the time when the object hits the ground.
After how many seconds does the object hit the ground?

morpeh [17]

Amy has $30 to spend on snacks and beverages for herself and her friends at the movie theater. The cost for nachos was $5. The cost for each beverage was half the cost of the nachos

Let x be the number of nachos and y be the number of beverages

The cost for nachos was $5. So the cost of 'x' nachos = 5x

The cost for each beverage was half the cost of the nachos.

The cost of each beverage = \frac{5}{2}= 2.5

so the cost of y beverage = 2.5 y

Cost of x nachos + cost of y beverage = total amount spend

5x + 2.5y = 30

Now we find x  and y intercept

When Amy does not buy any beverages we put y=0

5x + 2.5(0) = 30

5x = 30

x= 6. The x intercept is (6,0)

When Amy does not buy any nachos we put x=0

5(0) + 2.5y = 30

2.5y = 30

y=12. The y intercept is (0,12)

The graph is attached below

(b) The graph is a straight line. From the graph we can see that when Amy does not buy any nachos then she can spend #30 to buy 12 beverages .

when Amy does not buy any beverages then she can spend #30 to buy 6 nachos.

Solve for each indicated angle measure or variable in the figure.<br> m x
Elis [28]
If vertical angles are congruent you know

84=4x
21=x

You also know that angle M is supplementary to the angle
, measuring 84. Supplementary means it adds to 180 so if you take the difference you get

180-84=M
96=M


Also M is vertical to the last unknown angle so since vertical angles are congruent the last angle is also 96
