If f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (g – f)(3)?

1 answer:

5 0

F(x) = -x² + 4
g(x) = 6x

(g - f)(3) = 6(3) - (-(3)² + 4)
(g - f)(3) = 18 - (-9 + 4)
(g - f)(3) = 18 - (-5)
(g - f)(3) = 18 + 5
(g - f)(3) = 23

The perimeter of a semicircle is 81.212 yards. what is the semicircle's diameter?

adoni [48]

$\textit{circumference of a semicircle}\\\\ C=\pi r ~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=81.212 \end{cases}\implies 81.212=\pi r\implies \cfrac{81.212}{\pi }=r \\\\\\ \stackrel{\textit{its diameter is}}{2r\implies 2\left( \cfrac{81.212}{\pi } \right)} ~~ \approx ~~ 51.7$

You have an above ground pool that is 20 feet in diameter. One bag of sand does three square feet. How many bags of sand do you

r-ruslan [8.4K]

Answer: Number of sand bags are 105

Step-by-step explanation:

Alright, lets get started.

The diameter of pool is given as : $20 \ \text{feet}$

The radius of pool will be : $r=\frac{20}{2}=10$

So the area of the pool will be:

Area = $\pi r^2$

Area = $\pi *10^2$

Area = $100 \pi$

Area = $314.16$

3 square feet is covered by 1 sand bag, so

314.16 square feet will be covered by : $\frac{314.16}{3}$

So, no of sand bag = $104.7$

Rounding off to nearest number

Number of sand bags are 105 : Answer

Hope it will help :)

Answer:

1+6i

Step-by-step explanation:

Given:

f(x)=x^4 - 2x^3 + 38x^2 - 2 + 37

zero of f(x) = 1-6i

another zero of function = ?

Conjugate Zero theorem:

As per conjugate zero theorem, if a function f(x) has real coefficients and one of zero is a complex number then the conjugate of that complex number will also be a zero of that function i.e. complex zeroes will occur in complex conjugate pairs.

conjugate of 1-6i is 1+6i

hence another zero of f(x) will be 1+6i !
