Please help me!!! a = 8, b = 15, c = 17 √(24) √(46) √(161)

Here you can use the Pythagorean theorem which is a^2+b^2=c^2. Plug in the numbers given. 8^2+15^2=c^2. 64+225=c^2. 289=c^2. 17=c. So c=17. Hope I was able to help.

Leo bought a used car for x dollars. one year later the value of the car was 0.88x. which expression is another way to describe

Lesechka [4]

Initial price of car = $x

After one year the price of car = $0.88x

to find the change in price we subtract the price after one year from initial price.

It means change in price = (x-0.88x)= 0.12x

By this we can easily see that , price dropped by 0.12

Or we can say that price dropped by 12%

So option C is the correct answer

C) 12% decrease

Suppose a football player kicks a ball and gives it an initial upward velocity of 47 ft/s. Use the formula h(t)= -16t^2+47t+3 wh

statuscvo [17]

Answer:

Step-by-step explanation:

a. when t=0,h=3ft

$h(t)=-16 (t^2-\frac{47}{16}x+(\frac{47}{32} )^2)+\frac{47^2}{32^2} *16+3\\=-16(t-\frac{47}{32})^2+\frac{2209}{64}+3\\=-16(t-\frac{47}{32})^2+\frac{2209+192}{64}\\when~ t=\frac{47}{32}\\h=\frac{2301}{64}\\or~v^2-u^2=2gh\\\\0^2-47^2=2*(-32)h\\or h=\frac{47^2}{64}=\frac{2209}{64} \\height from the ground=\frac{2209}{64} +3=\frac{2301}{64}$

c.t=47/32 sec

time taken to fall 2301/64 ft=0*t+\frac{1}{2}*32*t^2

t^2=\frac{2301}{64*16}

t=\frac{\sqrt{2301}}{8*4}=\frac {47.97}{32}

total ~time=\frac{47+47.97}{32}=\frac{94.97}{32} sec
