Answer:

I think we are missing part of the question.

But if it's looking for how many students rode the bus and van on the way to the museum when the ratio was 2:5, it's 16 students in the van and 40 students in the bus.

On the way home, it was 14 students in the van and 42 students in the bus,   the ratio changes to 1:3

Step-by-step explanation:

Given

New function: [tex]y = 3 \cos(10 (x -\pi))[/tex]

We can assume the parent function to be:

[tex]y = \cos (x)[/tex]

The new function can be represented as:

[tex]y = A*\cos((\frac{2\pi}{B})(x-c))[/tex]

Where

A = Vertical stretch factor

B = Period

C = Right shift

By comparison:

[tex]y = A*\cos((\frac{2\pi}{B})(x-c))[/tex] to [tex]y = 3 \cos(10 (x -\pi))[/tex]

[tex]A = 3[/tex]

[tex]c = \pi[/tex]

[tex]\frac{2\pi}{B} = 10[/tex]

Solve for B

[tex]B = \frac{2\pi}{10}[/tex]

[tex]B = \frac{\pi}{5}[/tex]

Using the calculated values of [tex]A,\ B\ and\ c.[/tex] This implies that, the following transformations occur on the parent function:

Answer:

(x-1.3)^2 + (y+3.5)^2 = 37

In general, (x-c)^2 + (y-k)^2 = r^2 where (c,k) is the center and r is the radius.

So if the circle with radius 5 has center (3,-4) then it's equation is:

(x-3)^2 + (y+4)^2 = 25

Notice that the second term is (y+4)^2 because the y-coordinate is -4 and y-(-4) = y+4

Answer:

11.3097335 seems to have nothing with the question so the answer is

B) 18.8495559

Step-by-step explanation:

to find the perimeter (circumference?) do 2pi(r)

2 pi 3 = pi 6 = 18.8495559

since there is 40 percent missing, multiply the perimeter by 60% (part not missing)

18.8495559 * 60%

11.3097335

Answer:

39

Step-by-step explanation:

Plot the point (-7, -5). We are in quadrant 3.

We also know that tan θ = opp/adj.

Cot θ = adj/opp.

Let us use a^2 + b^2 = r^2 to show you how to find r, the radius aka hypotenuse.

Look: (-7)^2 + (-5)^2 = r^2

If you should ever need to find r, do this:

(-7)^2 + (-5)^2 = r^2

(49) + 25) = r^2

74 = r^2

Take the square root on both sides of the equation to find r.

sqrt{74} = sqrt{r^2}

sqrt{74} = r

It is ok to simplify the sqrt{74} but not needed.

We now have the three sides of the triangle that is form in quadrant 3.

We can now read cot θ from the triangle itself.

So, cot θ = adj/opp = (-7)/(-5) or 7/5.

No need to find r but I simply wanted to show you how it's done in case you are given a question where r must be found.

Answer:

They played 4 games and paid $19

Step-by-step explanation:

4x + 3 = 2x + 11    (You basically have to solve for X)

4x - 2x = 11 - 3      (move like terms together)

2x = 8

x = (8/2)

x = 4

This means they had to play 4 games.

To get how much they paid, just plug 4 into any one of those given equations (They will both give the same answer).

4x + 3 ⇒ 4(4) + 3 = $19

To check if this is true,

2x + 11 ⇒ 2(4) + 11 = $19

Therefore, they paid $19

Answer:

$19 and played 4 games

Answer:

Q5: S.A = 216 cm²

Q6: S.A = 254 cm²

Step-by-step explanation:

Q5:

Surface area of a cube = 6a²

a = 6 cm

Plug in the value of a

Surface area of the cube = 6(6²)

= 6(36)

S.A = 216 cm²

Q6:

Given:

Length (L) = 9 cm

Width (W) = 4 cm

Height (H) = 7 cm

Required:

Surface area

Solution:

Surface area of the rectangular prism = 2(LW + LH + HW)

Plug in the values

S.A = 2(9*4 + 9*7 + 7*4)

= 2(36 + 63 + 28)

= 2(127)

S.A = 254 cm²

Answer:

1. x = 58

2. x = 44

Step-by-step explanation:

#1:

2x + 5 + x + 2x + 7 + x = 360

Step 1: Combine 2x, x, 2x, and x to get 6x.

6x + 5 + 7 = 360

Step 2: Add 5 & 7 to get 12.

6x + 12 = 360

Step 3: Subtract 12 from both sides

6x = 360 - 12

6x = 348

Step 4: Divide both sides by 6.

x = 348/6

x = 58

#2:

3x + 2 + 2x + 2x + 1 + x + 5 = 360

Step 1: Combine like terms.

8x + 2 + 1 + 5 = 360

8x + 8 = 360

Step 2: Subtract 8 from both sides.

8x = 360 - 8

8x = 352

Step 3: Divide both sides by 8.

x = 352/8

x = 44

Step-by-step explanation:

Considering the situation, the hypotheses set that would determine if the proportion of households that support starting school earlier has changed this year is given by:

[tex]H_0: p = 0.65, H_\alpha: p \neq 0.65[/tex]

At the null hypotheses, it is tested if there has been no change, that is, the proportion is still of 0.65 = 65%, hence:

[tex]H_0: p = 0.65[/tex]

At the alternative hypotheses, it is tested if there has been a change, that is, the proportion is not of 0.65 = 65% anymore, hence:

[tex]H_\alpha: p \neq 0.65[/tex]

Given:

Daniel bought a bicycle for $80 and a helmet for $20.

Sales tax = 5%

To find:

The total amount of both items including tax.

Solution:

Price of bicycle (excluding tax)= [tex]\$80[/tex]

Price of helmet(excluding tax) = [tex]\$20[/tex]

Price of both items = [tex]\$80 + \$20[/tex]

                                =[tex]\$100[/tex]

Now, the sales tax is 5%. So,

Price of both items (including tax) = [tex]\$100+\dfrac{5}{100}(\$100)[/tex]

                                                        = [tex]\$100+\$5[/tex]

                                                        = [tex]\$105[/tex]

Therefore, the Daniel pays $105 for the two items, including tax.

Answer:

D.39

Step-by-step explanation:

Pythagorean Theorem: a^2+b^2=c^2 (Where a and b are the legs of the triangle and c is the hypotenuse)

Using this:

(AB)^2+(AC)^2=(BC)^2 (Pythagorean theorem)

15^2+36^2=(BC)^2 (Substitution)

225+1296=(BC)^2

(BC)^2=1521

BC=39

Answer:

D. 39

Step-by-step explanation:

The three interior angles of a right triangle always have a sum of 180°, and right angles always equal 90°.

Adding the angles shown here,

36+15+90 = 141

And, 180 - 141 = 39°.

Therefore, the length of angle BC is 39°.

Answer:

B

Step-by-step explanation:

Angles in a triangle add up to 180

Take 45 + 90 then subtract the answer from 180
