Answer:

The first step is

Take the square root of both sides of the equation

Step-by-step explanation:

we have

x^{2} =\frac{9}{16}

Solve for x

step 1

Take square root both sides

x=(+/-)\frac{3}{4}

the solutions are

x=+\frac{3}{4} and  x=-\frac{3}{4}

therefore

The first step is

Take the square root of both sides of the equation

Answer:

B

Step-by-step explanation:

To find the constant of proportionality between y and x, divide  \frac{y}{x} for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.

Using the method above, you should get:

Chart A = 2/5

Chart B = 1/5 (Correct Answer!)

Chart C = N/A

Hope this helps!

Select the correct answer. Simplify the expression.<br> (see the screenshot)
Sliva [168]

Answer:

Option D

Step-by-step explanation:

Given expression has been given as,

\sqrt[5]{224x^{11}y^8}

\sqrt[5]{224x^{11}y^8}=\sqrt[5]{2\times 2\times 2\times 2\times 2\times 7(x^{11})(y^8)}

                 =\sqrt[5]{(2^5)\times (7)(x^{10}\times x)(y^5\times y^3)}

                 =2^{\frac{5}{5}}\times 7^{\frac{1}{5}}\times x^{\frac{10}{5}}\times x^{\frac{1}{5}}\times y^{\frac{5}{5} }\times y^{\frac{3}{5} }

                 =2\times 7^{\frac{1}{5}}\times x^2\times y\times x^{\frac{1}{5} }\times y^{\frac{3}{5} }

                 =2x^2y\sqrt[5]{7xy^3}

Option D will be the answer.

Given that cosA = -8/17  and sinA is negative, determine the value of tanA.​
borishaifa [10]

Answer:

tan A = -15/8.

Step-by-step explanation:

sin^2a = 1 - cos^2A

= 1 - (-8/17)^2

= 225/289

So sin A= 15/17

tan A = sin A / cos A

=  15/17 / -8/17

= 15/-8

= -15/8.
