Describe how to transform (5 square root x^7)^3

1 answer:

7 0

(5 * sqrt(x^7))^3

Recall sqrt(x^2)=x

So we get (5*x^6 )^3

5*3 is 25, 6*3 is 18 (and exponent to an exponent multiplies)

Therefore the answer is 25x^18

Pythagorean theorem is $a^{2} + b^{2} = c^{2}$
and using that sin is opposite/hypotenuse, you can find the third side of the triangle.
$11^{2}+(adjacent)^{2} = 61^{2} \\ 121+ (adjacent)^{2} = 3721 \\ (adjacent)^{2}=3600 \\ adjacent = 60$
now you know adjacent is 60, so cos=60/61

Which equation and variable would be easiest to solve for in order to solve the system by substitution? y + x = 3 5x + 3y = -1

notsponge [240]

Answer:

Use y + x = 3 and solve for either x or y.

Step-by-step explanation:

Substitution is a method to solve a system of equations by substituting an expression from one equation into the other.

To begin, first solve one equation by isolating for one variable. Choose the equation which will have the least number of steps to do so.

y + x = 3 can be solve for x or y by subtracting the other variable. Since this only requires one step use this equation. Either variable can be used.

Ryan just got hired for a new job and will make $48,000 in his first year Ryan was told that he can expect to get raises of $3,5

Answer:

128500

Step-by-step explanation:

This is an arithmetic sequence with a common difference of 3500

The formula for an arithmetic sequence is

an = a1+d(n-1) where a1 is the first term and d is the common difference

an = 48000+ 3500(n-1)

We want n = 24

a24 = 48000+3500(24-1)

= 48000+3500(23)

=48000+80500

=128500
