the length of the arc fully around the circle (360°) is the circumference of the circle : 2×pi×r

and the arc length for 123° is then

2×pi×r×123/360

true or false? multiplying the parent linear function by 3/4 results in vertical stretch

### Answers

Transformations of Functions

f(x) ⇒ a*f(x)

This results in a **vertical stretch**, or **compression**.

When a > 1, we refer to this as a vertical stretch by a factor of *a*.When 0 < a < 1, we *typically* refer to this as a vertical compression by a factor of [tex]\dfrac{1}{a}[/tex].*

**There are ***multiple correct answers*** when asked about a, or vertical stretches/compressions.*

Let's say we're given [tex]\dfrac{1}{2}f(x)[/tex]. In this case, 0 < a < 1.

We could say the following:

f(x) underwent a vertical stretch by a factor of [tex]\dfrac{1}{2}[/tex].f(x) underwent a vertical compression by a factor of 2.

Both of the above responses are correct.

Solving the Question

We're given:

We multiply the parent function by [tex]\dfrac{3}{4}[/tex].

In this case, 0 < a < 1.

This results in a vertical stretch by a factor of [tex]\dfrac{3}{4}[/tex].This results in a vertical compression by a factor of [tex]\dfrac{4}{3}[/tex].

Answer

True and false. *Yes*, we did modify the vertical stretch factor of the function to induce a type of vertical stretch. *No*, it is not a vertical *stretch* per se, but it is rather a vertical compression.

[tex]\left \{ {{-b+c=2} \atop {b+c=8}} \right.[/tex]

=> b=3, c=5

b. delta = b^2 +4c

x1= [tex]\frac{-b+\sqrt{b^{2}+4c } }{-2}[/tex] =4

=> [tex]b-\sqrt{4c+b^{2} }[/tex]=8

x2=[tex]\frac{-b-\sqrt{b^{2}+4c } }{-2}[/tex]=1

=>2=b+[tex]\sqrt{b^{2}+4c }[/tex]

suppose : [tex]\sqrt{b^{2}+4c }[/tex] = a

=> [tex]\left \{ {{a+b=2} \atop {-a+b=8}} \right.[/tex]

=> a=-3

b=5

a=-3 => [tex]\sqrt{b^{2}+4c }[/tex] =-3 => b^2 +4c =9 =>5^2 +4c=9 => c=-4.

**Step-by-step explanation:**

because 11 +1 8n binary is qlways 100 bbecause 11 is in the 4th in the truth table of binary numbers and 100 is in the 5th so 11 + 1 = 4+1

100 = 5

pls mark it as the brainlyest answer

**Answer:**

**It's a.**

**Step-by-step explanation:**

Jacori wants to estimate the proportion on seniors who will participate in graduation. He interviews a simple random sample of 40 of the 514 seniors at his school. He find that 34 are planning to participate. Is the normal condition for finding a confidence interval met?

### Answers

Using the **Central Limit Theorem**, it is found that the **condition **is **not met**, as there are less than 10 failures.

What does the Central Limit Theorem states?

It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], **as long as** [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].

In this problem, **34 of the 40 **seniors are planning to participate in graduation, hence:

np = 34.n(1 - p) = 6 < 10.

Since there are **less than 10 failures**, the normal **condition **for finding a confidence interval is **not met**.

Anyone know what the answer is?

### Answers

17/20

you want to get the bottom numbers the same by multiplying:)

5x4= 20 , 4x5= 20

since you multiplied the fraction with the denominator 5 by 4 , you also multiply the number on top by 4

3x4= 12

and since the other fraction with the denominator 4 was multiplied by 5 , you multiply the number on top by 5

1x5= 5

now you add those 2 numbers up

5+12= 17

you put that number on top of the fraction: 17

and take the number you ————

got from the first step and

put it on the bottom: 20

and you get 17/20 or .85

### Answers

Answer:

Bridget flew 4100 miles.

Step-by-step explanation:

L + K + B = 7800

### Answers

**Answer:**

y+2x=4

**Step-by-step explanation:**

use the formula of equation of line

The **equation **of **line **is y= 4 - 2x.

What is slope?

A **line's slope **is determined by how its y **coordinate changes **in relation to how its x **coordinate** changes. y and x are the **net** **changes **in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the **slope**

Given co- **ordinates**:

A(-1,6) and B (3,-2)

**slope **= [tex](y_2 - y_1) / (x_2 - x_1)[/tex]

slope = ( -2 - 6)/ ( 3 -(-1))

slope = (-8) / (4)

**slope **= -2

Now, the **equation **of **line**

([tex]y-y_1) = m (x - x_1)[/tex]

(y- 6) = (-2)(x - (-1))

y-6 = (-2)(x + 1)

y-6 = -2x -2

y= 4 - 2x

Hence, the **equation **of **line **is y= 4 - 2x.

The reason why 2 x 3 or 2 times 3 would be six/6. Is because if you had 2 pairs of 3 items, you would get a total of 6 items. And if you had 3 pairs of 2 items, you would still have a total of 6 items.

in the lab, Kareem has two solutions that contain alcohol and is mixing them with each other. Solution A is 2% alcohol and Solution B is 7% alcohol. He uses 1200 milliliters of Solution A. How many milliliters of Solution B does he use, if the resulting mixture is a 4% alcohol solution?

### Answers

**Answer:**

800ml

**Step-by-step explanation:**

solution A= 2% alcohol

solution B=7% alcohol

1200ml=1.2L

1200ml=1200cm^3

X= solution B

solution A + solution B=(1200+x)cm^3

% alcohol= amount of alcohol/total solution(AorB)×100

☆in 1200ml of solution A there's

0.02x1200

2x12

=24ml of alcohol (in 1200ml of solution A)

0.07x X

=0.07Xml of alcohol (in some ml of solution B)

(24+0.07X)ml of alcohol in = solution A and solution B

solution A + solution B= 1200+X

0.04 (1200+X)=24+0.07X

48+0.04X=24+0.07X

48-24=0.07X-0.04X
