Yes. 2 squared is irrational number because no two of the same numbers multiplied equals 2. Not including decimals either.

Write an equation to express the value of h + k

Dahasolnce [82]

So since, they are the same distance from zero, they should be the oppposite of each other so in other words, k=-h and h=-k

so k+h=(subisute)k-k=-h+h=0 because they cancel

What is the rate of change for a linear function that passes through the points (8, -10) and (-6, 14)

Anna71 [15]

Answer: $m=-1.714$

Step-by-step explanation:

By definition, the slope of the line is described as "Rate of change".

You need to use the following formula to calcualte the slope of the line;

$m=\frac{y_2-y_1}{x_2-x_1}$

In this case you know that the line passes through these two points: (8, -10) and (-6, 14).

Then, you can say that:

$y_2=-10\\y_1=14\\\\x_2=8\\x_1=-6$

Knowing these values, you can substitute them into the formula for calculate the slope of a line:

$m=\frac{-10-14}{8-(-6)}$

Finally, you must evaluate in order to find the slope of this line. You get that this is:

$m=\frac{-24}{8+6}\\\\m=\frac{-24}{14}\\\\m=-\frac{12}{7}\\\\m=-1.714$

shtirl [24]

Answer:

The probability is 9.80%.

Step-by-step explanation:

The u.s. senate consists of 100 members, 2 from each state.

A committee of five senators is formed.

P(at least one from Your state) = 1- $\frac{98c5}{100c5}$

= 1- $\frac{67910864}{75287520}$

= $1-0.9020$

= 0.098

That is, 9.80%.

Ja'Kiree has a bunch of quarters and nickels in her piggy bank totaling $8.75. If Ja'Kiree has 26 quarters, how many nickels doe

evablogger [386]

Start off by stating your facts. You have a maximum of $8.75. We know that each quarter is 25 cents so we multiply 25x26 equaling 650. Yet we need a decimal so it would be $6.50. Each nickel is worth 5 cents so then you would minus $8.75 and $6.50 getting us to $2.25. Now divide it by 5 cents and you should get 45 nickels. You can also do this by stating that 10 nickels is 50 cents and go until you get 45
