Answer:

rise over run (change in y divided by change in x)

so it would go as follows

[tex]\frac{(3-1)}{(4-9)}[/tex]

= [tex]\frac{2}{-5}[/tex]

= [tex]-\frac{2}{5}[/tex]

Answer: - (2/5)

Step-by-step explanation:

(y2-y1) / (x2- x1) =

(1-3) / (9-4)

= - (2/5)

Answer:

  y = 2x +2

Step-by-step explanation:

The horizontal stretch of f(x) by a factor of k is ...

  f(x/k)

Here, that means you want ...

  y = 4(x/2) +2

  y = 2x +2

Answer:

3/8 because 3/8 as a percent is 37.5 percent

Step-by-step explanation:

Answer:

3/8 is greater

Step-by-step explanation:

3/8 as a percent is 37.5

37.5% > 25%

Therefore 3/8 is greater

Tip:

Covent one to the other unit

like 3/8 to a percent or 25% as a fraction.

But if you are looking for which is greater in fraction form then 25%

Answer:

1.  144  2. 16 3. 1   4. 3x-6  

Step-by-step explanation:

So think of this as a function in a function.  So you work from the inside to the outside.  So for problem 1, we start with f(4)) [you read it "f of 4"] so what is the solution when x = 4, since f(x) means the function of x so f(4) means 'the function of 4' inside f(x).  

Since f(x) = 3x then f(4) = 3(4) [notice how you substitute the 4 everywhere you see a letter x]

so f(4) = 12, now you work the next part h(f(4)) since f(4)=12 then h(12)

So take the h(x) function which is h(x) = [tex]x^{2}[/tex] then h(12) = [tex]12^{2}[/tex] so h(12) = 144

Answer:

33m

Step-by-step explanation:

If the ratio of the new length to the old length is 11:8 (simplified ratio)

I like to set up a proportion, like this,

x/24 = 11/8, where x is the undefined new length

x*8 = 24*11 (cross multiply)

8x = 264 (multiply)

x = 33 (divide 8 by both sides)

The new length is 33m.

Hope I helped! Good Luck!

Answer:

33m

Step-by-step explanation:

The 8 part of the ratio refers to the old length 24m

Divide by 8 to find the value of one part of the ratio

24m ÷ 8 = 3m ← value of 1 part of the ratio, then

11 parts = 11 × 3 = 33m

Thus

33m : 24m = 11 : 8

Answer:

a) The length of segment AC is approximately 5.83 centimeters.

b) The angle ACD is approximately 34.5º.

Step-by-step explanation:

a) Since [tex]AB \perp BC[/tex], the length of segment [tex]AC[/tex] is determined by Pythagorean Theorem, that is:

[tex]AC = \sqrt{(5\,cm)^{2}+(3\,cm)^{2}}[/tex]

[tex]AC \approx 5.831\,cm[/tex]

The length of segment AC is approximately 5.831 centimeters.

b) Since [tex]AB \perp BC \perp AD[/tex], the length of segment [tex]AD[/tex] is determined by this Pythagorean identity:

[tex]AD = \sqrt{(3\,cm)^{2}+(5\,cm)^{2}+(4\,cm)^{2}}[/tex]

[tex]AD \approx 7.071\,cm[/tex]

The angle ACD is determined by the following trigonometric expression:

[tex]\cos C = \frac{AC}{CD}[/tex]

[tex]\cos C = \frac{5.831\,cm}{7.071\,cm}[/tex]

[tex]\cos C = 0.825[/tex]

[tex]C = \cos^{-1} 0.825[/tex]

[tex]C \approx 34.448^{\circ}[/tex]

The angle ACD is approximately 34.448º.

Answer: Option D is correct.

Step-by-step explanation: An exponential function is in the form of  where a is the initial value and b≠ 0 , b >1 .

Given: The function f(x) = y =            ......[1]

The domain is all real numbers and the range is y > 0.

y-intercept defined as the graph crosses the y-axis.

Substitute the value of x= 0 in [1] to solve for y;

y =   = 4

y-intercept = (0, 4)

End behavior:

when b =3 >1

then;

as  ,  

as   ,  

therefore, the only graph which represents the function y =    is Option D

Answer:

15 / 25

Step-by-step explanation:

Cos is found by doing adjacent / hypotenuse. For this triangle, the adjacent of C is 15, the opposite is 20, and the hypotenuse is 25. Therefore, cosC = 15/25.

Step-by-step explanation:

Answer: The first step would be to multiply the first equation by 3 and the second by 2 so you can eliminate x.

Answer:

(2, 0 )

Step-by-step explanation:

Given the 2 equations

2x + 3y = 4 → (1)

3x - 7y = 6 → (2)

Multiplying (1) by 3 and (2) by - 2 and adding the result will eliminate x

6x + 9y =  12 → (3)

- 6x + 14y = - 12 → (4)

Add (3) and (4) term by term to eliminate x

0 + 23y = 0

23y = 0

y = 0

Substitute y = 0 into either of the 2 equations and solve for x

Substituting into (1)

2x + 3(0) = 4

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 )

Answer:

  h(0) = 10

  h(4) = 16

Step-by-step explanation:

The second part of the function definition applies when x=0.

  h(x) = 2x^2 -3x +10

  h(0) = 0 + 0 + 10 = 10

__

The third part of the function definition applies when x=4.

  h(4) = 2^4 = 16

Answer:

Voluntary Sample A voluntary sample is one of the main types of non-probability sampling methods. A voluntary sample is made up of people who self-select into the survey. Often, these folks have a strong interest in the main topic of the survey.

Answer:

Option B

Step-by-step explanation:

36x^3-x=0,

x(36x^2-1)=0,

x((6x)^2- (1)^2)=0,

x(6x-1)(6x+1)=0

Your solution would be (6x-1)(6x+1) accordingly.

Answer:

F=90

D=37

E=53

f=18.3

d=11

e=14.6

Step-by-step explanation:

Triangle Sum Theorem means 180-37-90=E.  So, E=53 degrees.

Sin(37)=[tex]\frac{11}{f}[/tex]

fsin(37)=11

f=[tex]\frac{11}{sin(37)}[/tex]

f=18.3

Tan(37)=[tex]\frac{11}{e}[/tex]

etan(37)=11

e=[tex]\frac{11}{tan37}[/tex]

e=14.6

Make sure your calculator is in DEGREE mode.

Answer:

The answer is B because it is the complete opposite. Inverse basically means opposite.
