Answer: y-4x^{2} +12x+9=0

Step-by-step explanation:  the standard form of a quadratic equation can be writen in the form: ax2 + bx + c = 0. To transform the given equation into the standard form, we need to solve it:

y=(2x+3)^{2}

y=4x^{2} +2*2x*3+3^{2}

y=4x^{2} +12x+9

no we reorganize it, and equal it to zero:

y-4x^{2} +12x+9=0

Find the product of 4cis (pi/4) times 5cis (pi/6) in polar form.
KengaRu [80]

We have the following expression

4\cdot\text{cis(}\frac{\pi}{4})\cdot5\text{cis(}\frac{\pi}{6})

This is equivalent to

4\cdot\text{cis(}\frac{\pi}{4})\cdot5\text{cis(}\frac{\pi}{6})=(4\times5)cis(\frac{\pi}{4}+\frac{\pi}{6})

Since

\frac{\pi}{4}+\frac{\pi}{6}=\frac{6\pi+4\pi}{24}=\frac{10}{24}\pi=\frac{5}{12}\pi

we have that

4\cdot\text{cis(}\frac{\pi}{4})\cdot5\text{cis(}\frac{\pi}{6})=20cis(\frac{5\pi}{12})

Therefore, the answer is the second option from top to bottom.

Two sides of a parallelogram are 500 feet and 790 feet. The measure of the angle
Nat2105 [25]

Answer:

  • 215117 ft²

Step-by-step explanation:

Assumed the base is the longer side.

<u>The height of the parallelogram is:</u>

  • h/500 = sin 33°
  • h = 500 sin 33°
  • h =  272.3 ft

<u>The area is:</u>

  • A = bh
  • A = 790*272.3 = 215117 ft²

Please help me <br> can u explain how to do this
Ghella [55]

Answer:

x=41

Step-by-step explanation:

so since this is a right triangle you can use the Pythagorean Theorem to find the missing side. the two sides you know are 'a' and 'b' and the missing side is 'c'. the theorem says that:

a^2+b^2=c^2

so:

9^2 +40^2=c^2

solve for the exponents:

81 +1600=c^2

1681=c^2

and now, since 1681 is the missing side's length squared, we must find the square root of 1681, which is 41

hope this helps :)
