How is the Pythagorean theorem related to the distance formula?Explain.

Answers

Answer:

If you plot 2 points on a graph right, you can form a triangle between the 2 points. You can determine the legs's sizes using the coordinates of the points. Pythagorean theorem is then used to find the hypotenuse, which IS the distance from one point to the other. Hope that helps.

There are one hundred forty-two students in a high
school band. These students represent two ninth
of the total students in the high school. How many
students attend the school?

Answers

Answer:

639 students attend the highschool

Step-by-step explanation:

Find one-ninth of the students

Since 142 students is two-ninths of students, we would divide

1) 142/2=71

71 students is only one ninth of the students, we need to find 9/9 of students

2) 71*9 = 639

639 students attend school

There is a total of 639 students in the school.

What is a fraction?

If we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

Let's say the number of students in the school is x

Then,

Since 2/9 of it are in the school band

So,

(2/9) x = 142

x = 639

Hence "There is a total of 639 students in the school".

Evaluate the step function for the given input values.

-1, -1sx<2
g(x) =
3, 25x< 4
5, x 24
9(2) =
g(-2) =
g(5) =

Answers

Answer:

I would, but the way this is set up is VERY confusing. sorry. maybe try to fix it after copying and pasting to make sure it makes sense.

The evaluated values of the step function for the given input values are as g(-2) = -4, g(2) = 3, and g(5) = 5.

To evaluate the step function g(x) for the given input values, we need to follow the conditions specified for each interval.

Given the step function:

g(x) =

-4, x < -1

-1, -1 ≤ x < 2

3, 2 ≤ x < 4

5, x ≥ 4

Let's evaluate the step function for each input:

g(-2):

Since -2 is less than -1, the condition for the first interval is satisfied. Therefore, g(-2) = -4.

g(2):

Since 2 is less than or equal to 4, the condition for the second interval is satisfied.  Therefore, g(2) = 3.

g(5):

Since 5 is greater than or equal to 4, the condition for the last interval is satisfied. Therefore, g(5) = 5.

Hence, we have:

g(-2) = -4

g(2) = 3

g(5) = 5

Answers

Answer:

8b + 7m + 4n = -10

Step-by-step explanation:

(8b + 8) + (7m – 2) + (4n + 4)

First thing to do is to try to open the brackets, so we have

8b + 8 + 7m - 2 + 4n + 4 =

Next, we collect like terms, so that we have

8b + 7m + 4n + 8 - 2 + 4 =

8b + 7m + 4n + 10 =

And rearranging, we have that

8b + 7m + 4n = -10

B. 6x2 – x+7
C. 12x2 - x-7
D. -6x2 – 3x-7

Answers

Answer:

A

Step-by-step explanation:

We have the two functions:

[tex]f(x)=3x^2-2x\text{ and } g(x)=9x^2-x+7\\[/tex]

And we want to find:

[tex](f-g)(x)[/tex]

This is equivalent to:

[tex]=f(x)-g(x)[/tex]

Hence, by substitution:

[tex]=(3x^2-2x)-(9x^2-x+7)[/tex]

Distribute:

[tex]=(3x^2-2x)+(-9x^2+x-7)[/tex]

Rearrange:

[tex]=(3x^2-9x^2)+(-2x+x)+(-7)[/tex]

Combine like terms:

[tex]=-6x^2-x-7[/tex]

Hence, our answer is A.

What is the inverse of the function f(x) = one-quarterx – 12? h(x) = 48x – 4 h(x) = 48x + 4 h(x) = 4x – 48 h(x) = 4x + 48

Answers

Answer:

The inverse of the function f(x) is h(x) = 4x + 48 ⇒ (D)

Step-by-step explanation:

To find the inverse of a function do these steps

Replace f(x) by ySwitch x and ySolve to find the new yReplace y by [tex]f^{-1}[/tex](x)

Let us do these steps to solve the equation

∵ f(x) = [tex]\frac{1}{4}[/tex]x - 12

→ Replace f(x) by y

∴ y = [tex]\frac{1}{4}[/tex]x - 12

→ Switch x and y

∴ x =  [tex]\frac{1}{4}[/tex]y - 12

→ Add 12 to both sides

∵ x + 12 =  [tex]\frac{1}{4}[/tex]y - 12 + 12

∴ x + 12 =  [tex]\frac{1}{4}[/tex]y

→ Multiply each term by 4

∵ 4(x) + 4(12) = 4([tex]\frac{1}{4}[/tex]y)

∴ 4x + 48 = y

→ Switch the two sides

∴ y = 4x + 48

→ Replace y by h(x)

∴ h(x) = 4x + 48

∴ The inverse of the function f(x) is h(x) = 4x + 48

Answer:

h(x) = 4x + 48 ⇒ (D)

It was a military-looking Jeep, like an armored Hummer, only it didn't have any military insignia on it. The car skidded to a stop just in front of me, and I jumped back and lost my balance and ended up on the road. I felt the doors open near me, and then saw a confusion of booted feet moving close by. I looked up and saw a bunch of military-looking guys in coveralls, holding big, bulky rifles and wearing hooded gas masks with tinted face-plates. I barely had time to register them before those rifles were pointed at me. I'd never looked down the barrel of a gun before, but everything you've heard about the experience is true. You freeze where you are, time stops, and your heart thunders in your ears. I opened my mouth, then shut it, then, very slowly, I held my hands up in front of me. The faceless, eyeless armed man above me kept his gun very level. I didn't even breathe. Van was screaming something and Jolu was shouting and I looked at them for a second and that was when someone put a coarse sack over my head and cinched it tight around my windpipe, so quick and so fiercely I barely had time to gasp before it was locked on me. I was pushed roughly but dispassionately onto my stomach and something went twice around my wrists and then tightened up as well, feeling like baling wire and biting cruelly. I cried out and my own voice was muffled by the hood. I was in total darkness now and I strained my ears to hear what was going on with my friends. I heard them shouting through the muffling canvas of the bag, and then I was being impersonally hauled to my feet by my wrists, my arms wrenched up behind my back, my shoulders screaming. I stumbled some, then a hand pushed my head down and I was inside the Hummer. More bodies were roughly shoved in beside me. "Guys?" I shouted, and earned a hard thump on my head for my trouble. I heard Jolu respond, then felt the thump he was dealt, too. My head rang like a gong. "Hey," I said to the soldiers. "Hey, listen! We're just high school students. I wanted to flag you down because my friend was bleeding. Someone stabbed him." I had no idea how much of this was making it through the muffling bag. I kept talking. "Listenthis is some kind of misunderstanding. We've got to get my friend to a hospital" Someone went upside my head again. It felt like they used a baton or somethingit was harder than anyone had ever hit me in the head before. My eyes swam and watered and I literally couldn't breathe through the pain. A moment later, I caught my breath, but I didn't say anything. I'd learned my lesson. In three to five sentences, explain Marcus' current stage of identity development. Use examples from the text.
