Answer: $\boxed{Sol=\{\dfrac{7}{4} \}}\\$

I suppose 17x^ means 17x².

and that we must solve the equation.

Step-by-step explanation:

$(x-3)(x-5)-(4x+1)(1-4x)=14x^2\\\\x^2-3x-5x+15+(4x+1)(4x-1)=17x^2\\\\x^2-8x+15+16x^2-1=17x^2\\\\-8x+14=0\\\\8x=14\\\\x=\dfrac{7}{4} \\\\\boxed{Sol=\{\dfrac{7}{4} \}}\\$

- From a standing position, Meg jumps

Readme [11.4K]

Step-by-step explanation: Victor jumps farther than Meg.

If Victor jumps 9 feet and 2 inches and Meg jumps 7 feet and 4 inches, that means that Victor jumps 1 foot 10 inches farther than Meg.

Lets learn our conversations: 1 foot = 12 inches

If Victor jumps 9 feet, that means that 9 feet = 108 inches + 2 inches, which equals 110 total inches jumped.

If Meg jumps 7 feet, that means that 7 feet = 84 inches + 4 inches, which equals 88 total inches jumped.

110 - 88 = 22 inches.

So, Victor jumped 22 inches farther than Meg, or 1 foot and 10 inches farther than Meg.

The area of the region in the first quadrant between the graph of y = k*sin(x) and x-axis (where k > 0 ) on the closed interv

astraxan [27]

Note that $0\le k\sin x\le k$ in the given closed interval, so the area is exactly given by the definite integral

$\displaystyle\int_0^\pi k\sin x\,\mathrm dx$

(no absolute values needed!)

Integrating gives

$-k\cos x\bigg|_{x=0}^{x=\pi}=-k(\cos\pi-\cos0)=-k(-1-1)=2k$
