What is the value of c? O 4 units O 5 units O 6 units O 7 units

Aleksandr [31]

The value of c is 5 units.

Step-by-step explanation:

Given,

WY = a = 4

ZY = b = 3

As WYZ is forming a right angle triangle, therefore, we can use pythagorean theorem to find the value of c

$a^2+b^2=c^2\\(4)^2+(3)^2=c^2\\16+9=c^2\\c^2=25$

Taking square root on both sides

$\sqrt{c^2}=\sqrt{25}\\c=5$

The value of c is 5 units.

Complete the table of values for this absolute value function. Then use the drawing tool(s) to graph the function. F(x)-2|x+1|-1

rusak2 [61]

Answer:

Please check the explanation!

Step-by-step explanation:

Given the equation

$f\left(x\right)=-2|x+1|-1$

As some of the absolute rules are:

$\left|a\right|=a,\:a\ge 0$

$\:|-a|=a,\:\quad \:a>0$

NOW, let us solve!

Let us substitute all the table values

Putting x = -4

$y=-2\left|-4+1\right|-1$ ∵ $\mathrm{Apply\:absolute\:rule}:\quad \left|a\right|=a,\:a\ge 0$

$y=-6-1$

$y=-7$

So, when x = -4, then y = -7

Putting x = -3

$y=-2|-3+1|-1\:$

$y=-4-1$

$y=-5$

when x = -3, then y = -5

Putting x = -2

$y=-2\left|-2+1\right|-1$

$y=-2-1$

$y=-3$

when x = -2, then y = -3

Putting x = -1

$y=-2\left|-1+1\right|-1$

$y=-0-1$

$y=-1$

when x = -1, then y = -1

Putting x = 0

$y=-2\left|0+1\right|-1$

$y=-2-1$

$y=-3$

when x = 0, then y = -3

Putting x = 1

$y=-2\left|1+1\right|-1$

$y=-4-1$

$y=-5$

when x = 1, then y = -5

Chet needs to buy 4 work shirts, all costing the same amount. The total cost before Chet applies a $25 gift certificate can be n

Alborosie

Let us use x as the cost before Chet would apply a $25 gift certificate. Based on the problem, we can see that the original cost of the product cannot be more than 75 which means that it can be equal to 75 or less than 75. We can actually express the inequality as x< or = 75 since we are looking for the cost before Chet applied the $25 gift certificate. This means that we do not need to add in the 25 yet since the question asks for the cost before the application of the discount. - Credits, Taskmasters and Hegans

Find an equation for this I WILL MARK BRAINLIEST AND GIVE THANKS

Reika [66]

Answer:

$\displaystyle Dependency\:[Infinitely\:Many\:Solutions]$

Explanation:

In the bottom equation, moving $\displaystyle -2x$ to the oppocite side will give you the linear standard equation above it, therefore numerous solutions will occur.

I am joyous to assist you at any time.

A train that is 1 mile long starts through a tunnel that is also 1mile long . The train is traveling 15 miles per hour. How long

bearhunter [10]

12 minutes because it is three miles into for the train to go completely in and out (one mile for the nose to enter, on mile for the nose to exit and tail enter, and one mile for tail to exit). 3/15=x/60
