PLEASE HELP ME Ill Mark Brainliest ! I Added Some Extra Points Too

Answers

Answer 1

We want to find all the solutions to the equation [tex]f(x)=0[/tex]. Wich means that we want to find all values of [tex]x[/tex] such that [tex]y=0[/tex] (recall f(x)=y).

By looking at the graph, when does [tex]y=0[/tex]? That's right, exactly over the X axis!

The solutions to the equation are the X coordinates where the graph crosses the X axis.

They are -5,-2 and 4.

Answers

Answer:

1. the first one

2.  the second one

Step-by-step explanation:

The open circle means that it isn't equal to so x is less than two because of where its headed on the line

    The second one is equal to becasue it's filled in. Once again X is less than this number beacause of which way it is going on the graph                    

for the first one it would be x < 2
and for the second it would be x < -4.25

Help please! This has to do with the Pythagorean theorem.

Answers

so the pythagorean theorem is:

a^2+b^2=c^2

where a and b are the sides, and c is the hypotenuse.

to fill this in, we will get:

x^2+8^2=14^2

now we will need to solve.

x^2+8^2=14^2
x^2+64=196
x^2=132
x=11.5

Answer: It's 11.5

Explanation ( took so long)

[tex]C = \sqrt{a^{2} + b^{2} }\\14 = \sqrt{8^{2} + b^{2} }\\14 = \sqrt{64 + b^{2} }\\14^{2} = 64 + b^{2} \\196 = 64 + b^{2} \\64 +b^{2} = 196\\b^{2} = 196 - 64\\b^{2} =132\\b = \sqrt{132} \\b = 11.48[/tex]

You compare the happiness of people forced to smile with those of people forced to frown. Both groups have the same number of participants. The mean happiness level in the smile group is 20. The mean happiness level in the frown group is 19. The standard deviation of both groups is 20. The effect size is:_________

Answers

Answer:

0.05

Step-by-step explanation:

The Effect size  = (Difference in Means) / (Standard deviation)

= (20 - 19) / 20

= 1/20

= 0.05

6. To solve the equation in the box for the
value of x, Michele started by adding 5 to both
sides. To get the correct answer, what must
Michele do next?
A divide both sides by 10
B. divide both sides by 3
C. multiply both sides by 10
D. multiply both sides by 3

Answers

After adding 5 to both sides what did Michele get? Let's see

[tex]3x-5 + 5 = -10 + 5\\3x= -5[/tex]

If she wants to find the value of [tex]x[/tex] then she needs to have only the variable [tex]x[/tex] on the left hand side. What she must do so that [tex]3x[/tex] becomes just [tex]x[/tex]?  What do you have to do to the number 3 so it becomes a 1? That's right, she must divide by 3!

So, after dividing both sides by 3:

[tex]\frac{3x}{3} = \frac{-10}{3} \\\\\boxed{x=\frac{-10}{3}}[/tex]

Thus, the correct answer is letter B
