(3x + 5)° + (10x - 7)° = 180°

13x + (-2) = 180

13x = 180 + 2

13x = 182

x = 14

∠QRT = 3 * 14 + 5 = 42 + 5 = 47°

∠TRS = 10 * 14 - 7 = 140 - 7 = 133°

Answer:

The maximum height of the volleyball is 12.25 feet.

Step-by-step explanation:

The height of the volleyball, h(t), is modeled by this equation, where t represents the time, in seconds, after that ball was set :

$h(t)=-16t^2+20t+6$ ....(1)

The volleyball reaches its maximum height after 0.625 seconds.

For maximum height,

Put $\dfrac{dh}{dt}=0$

Now put t = 0.625 in equation (1)

$h(t)=-16(0.625)^2+20(0.625)+6\\\\h(t)=12.25\ \text{feet}$

So, the maximum height of the volleyball is 12.25 feet.

Nathan is itemizing deductions on his federal income tax return and had $5800 in his medical expenses last year. If his AGI was

victus00 [196]

Multiply his AGI by 7.5% to find the amount medical needs to meet before deducting:

46,000 x 0.075 = $3,450

He can deduct any amount over $3450.

Subtract that from his medical total to find the amount he can deduct:

5800 - 3450 = 2350

He can deduct $2,350.
