The answer is 21

First you po perenthies which would be 8-6=2 the equation now is 5+4×(2)2

Then you to exponents which would be 2×2=4 the equation now is 5+4×4

Now you multiply 4×4=16 the equation is now 5+16

Now you add 5 and 16 to get 21

Choose the TWO factored binominals for the expression: x2+6x – 27 Question 6 options: A) (x - 3) B) (x - 9) C) (x + 6) D) (x + 9
Vera_Pavlovna [14]

Answer:

A) x-3 and D) x+9

Step-by-step explanation:

x^2 + 6x - 27

You need to find two numbers that multiply to -27 and add up to 6

Those two numbers are -3 and 9, because 9 * -3 = -27 and 9+ -3 = 6

So you add those to x and those are your two factored binomials

(x-3) and (x+9)

True or false: sec^-1(0.5) is undefined. explain your answer
ICE Princess25 [194]

Here we get the statement:

"sec^-1(0.5) is undefined"

And we want to see if this is true or false, so let's use the properties that we know to find that this is false.

Remember that the sec function is defined as:

sec(x) = \frac{1}{cos(x)}

Then we will have:

sec^{-1}(x) = (\frac{1}{cos(x)})^{-1} =  cos(x)

Then is really trivial to see that:

sec^{-1}(0.5) =  cos(0.5) = 0.878

Then we can conclude that the function is not undefined at 0.5, so the statement is false.

Below you can see the graph of the given function, and you will see that it is never undefined.

The midpoint of gh is m(4,-3). One endpoint is G(-2,2). Find the coordinates of endpoint H
Mars2501 [29]

Answer:

Step-by-step explanation:

(-2 + x)/2= 4

-2 + x = 8

x = 10

(2 + y)/2 = -3

2 + y = -6

y = -8

(10, -8) for endpoint H

You work 4 hours on Saturday and 8 hours on Sunday. You also receive a $50 bonus. You earn $164. How much did you earn per hour?
Marina86 [1]
To find the hourly rate, we would first need to take the total earnings and subtract the bonus. $164 - $50 = 114 This gives us the total money earned for hourly work. Then we need to add the total hours worked: 4 + 8 = 12. Lastly, we need to take the total money earned and divide it by the total hours worked: 114 / 12 = 9.50 or $9.50 per hour. The equation could look like: 4h + 8h + $50 = $165
