2 17/30 gallons of paint altogether

because 1/2 plus 2/5 plus 1 2/3 is 77/30 and if you simplify that it is 2 7/30

72 is equal to 80% of a number n. Write and solve and equation to find n. Write the percent as a decimal

muminat

Hey there!!

80% = 80/100 = 0.8

80% of 'n' = 72

0.8n=72

n = 72/0.8

n = 90

Hence, the number is 80!

Hope it helps!

Find a, b , and h so that f(x)= a sin (b(x-h))<br> f(x)=5cosx+2sinx

TiliK225 [7]

$a\sin(b(x-h))=a\sin(bx)\cos(bh)-a\cos(bx)\sin(bh)$

For this to be equivalent to $5\cos x+2\sin x$ , you require $b=1$ and

$\begin{cases}a\cos h=2\\-a\sin h=5\end{cases}$

Dividing the second equation by the first gives

$\dfrac{-a\sin h}{a\cos h}=-\tan h=\dfrac52\implies h=\arctan\left(-\dfrac52\right)=-\arctan\dfrac52$

Meanwhile, you also get

$a\cos\left(-\arctan\dfrac52\right)=2\implies a\cos\left(\arctan\dfrac52\right)=\dfrac{2a}{\sqrt{29}}=2\implies a=\sqrt{29}$

So,

$f(x)=5\cos x+2\sin x=\sqrt{29}\sin\left(x+\arctan\dfrac52\right)$

A tennis racket in Sport City costs $180 and is discounted by 15%. The same model racket costs $200 at Tennis World and is on sa

scZoUnD [109]

Sport City is the better deal.

Sport City = 180 - (180 x .15) = $153
Tennis World = 200 - (200 x .20) = $160
