Help me pleasee , timed
solong [7]

Answer:

The second alternative is correct

Step-by-step explanation:

We have been given the expression;

(x^{27}y)^{\frac{1}{3}}

The above expression can be re-written as;

(x^{27})^{\frac{1}{3}}*y^{\frac{1}{3}}\\\\(x^{27})^{\frac{1}{3}}=x^{27*\frac{1}{3}}=x^{9}

On the other hand;

y^{\frac{1}{3}}=\sqrt[3]{y}

Therefore, we have;

x^{9}\sqrt[3]{y}

John's patio is 5 feet long<br> and has an area of 1.30<br> square feet<br> How wide is the patio?
Sophie [7]

Step-by-step explanation:

so, I assume the patio is a true rectangle.

the area of a rectangle is

length × width

in our case that means

1.3 = 5 × width

width = 1.3 / 5 = 0.26 ft

so, this is just a very narrow strip of 0.26ft × 5 ft.

I would not call that a patio ...

or was it a typo, and the area is actually 30 ft² ?

then we would have

30 = 5 × width

width = 30 / 5 = 6 ft

If pis inversely proportional to the square of q, and p is 23 when q is 4, determine p
Misha Larkins [42]

Answer:

p\ =\ 92

Step-by-step explanation:

Given

p\ \alpha\ \frac{1}{q^2}

p =23; q=4

Required

Find p, when q = 2

We have:

p\ \alpha\ \frac{1}{q^2}

Express as equation

p\ =\ \frac{k}{q^2}

Make k the subject

k =pq^2

When: p =23; q=4

k =23 * 4^2

k =368

When q = 2, we have:

p\ =\ \frac{k}{q^2}

p\ =\ \frac{368}{2^2}

p\ =\ \frac{368}{4}

p\ =\ 92

Solve the trigonometric equation<br> 3-3cosx=2 sin^2 x
Zina [86]
= 3 - 3cos x - 2(1- cos^2 x)
= 2cos^2 x - 3cos x + 1
=(cos x -1)(cosx - 1/2)
   now cos x = 1    or cos x= 1/2 
   draw a graph we get = + ve values
  hence .. 0 ,180,360 and 60,240, degrees in range x<2pi
