Answer:

I got this answer from the answer above but put it into my own words...

Sasha is incorrect. She concluded that the object hit the ground at -1.71 seconds, when that is impossible because there is no way an object can hit the ground in negative seconds. What she could have done was used the quadratic formula because it works for every problem, but it does take more time than any other problem.

Answer:

Her answer is wrong because she the object cannot hit the ground at negative seconds. She could’ve have used other methods because she used the quadratic formula. The advantages is that it works for every situation. The disadvantages is that it takes longer. She should’ve used a different method.

A sinusoidal function whose period is π/2 , maximum value is 10, and minimum value is −4 has a y-intercept of 3. What is the equ
Eddi Din [679]

Answer:

f(\theta)=3+7sin(4\theta)

Step-by-step explanation:

The sinusoidal function has a general form of:

f(\theta)=Y+Asin(k\theta)

The period is given by:

P=\frac{2\pi}{k}\\\frac{\pi}{2}= \frac{2\pi}{k}\\k=4

Y is the y-intercept, thus y = 3.

At the maximum value:

f(max) = Y+A\\10 = 3+A\\A=7

At the minimum value:

f(min) = Y-A\\-4 = 3-A\\A=7

Therefore, the equation of the function described is:

f(\theta)=3+7sin(4\theta)

Rewrite the following expression using the properties of logarithms. log2z+2log2x+4log9y+12log9x−2log2y
kramer
Use the rules of logarithm:
1. log(x)+log(y)=log(xy)
    log(x)-log(y)=log(x/y)
2. k*log(x) = log(x^k)
    log(x)/k = log(x^(1/k))

<span>log(2z)+2log(2x)+4log(9y)+12log(9x)−2log(2y)
=</span>log(2z)+log(4x^2)+log(9^4y^4)+log(9^12x^12)−log(4y^2)
=log(2z)+log(4x^2)+log(6561y^4)+log(282429536481x^12)−log(4y^2)
=log(59296646043258912 * x^14 * y^6 * z)

Two containers are mathematically similar.Their volumes are 54cm³ and 128cm³.The height of the smaller container is 4.5cm.Calcul
alexira [117]

Answer:

6 cm

Step-by-step explanation:

If the linear scale factor of two solids is k, then the volume scale factor is k^3.

The volume scale factor is 128/54 = 64/27 = (4/3)^3.

The linear scale factor is 4/3.

4.5 cm * 4/3 = 6 cm

Answer: The height of the larger container is 6 cm.
