6) Find The Area Of Each Polygon

Answers

Answer 1

Let's find sides one by one

[tex]\\ \tt\hookrightarrow a^2=2^2+3^2=4+9=13\implies a=\sqrt{13}=3.2[/tex]

[tex]\\ \tt\hookrightarrow b=\sqrt{2^2+4^2}=\sqrt{20}=4.2[/tex]

[tex]\\ \tt\hookrightarrow x=\sqrt{1^2+4^2}=\sqrt{17}=4.1[/tex]

Now

[tex]\\ \tt\hookrightarrow s=\dfrac{4.2+4.1+3.2}{2}=5.7[/tex]

Apply herons formula

Area

[tex]\\ \tt\hookrightarrow \sqrt{5.7(5.7-3.2)(5.7-4.1)(5.7-4.2)}=\sqrt{5.7(2.5)(1.6)(1.5)}=5.84units^2[/tex]

Answer:

The answer is B

Step-by-step explanation:

Find the axis of symmetry

Use the formula -b/2a

2x^2-8x+6

- (-8)/2(2)

8/4

2

The axis of symmetry is at x=2, which means that the vertex is at x=2

Substituting x=2 into the quadratic:

2(2)^2-8(2)+6

2*4-16+6

8-16+6

-2

The vertex is at (2,-2)

The graph where this applies is B.

Therefore, the answer is B.

HELP PLEASE! Find the area of the figure.

Answers

Answer: 36 square units.

Step-by-step explanation:

First, you can separate the figure into a 4x6 rectangle and a 6x4 isosceles triangle. You can find the area of the rectangle by using the rectangle area formula, A = l x w .

4 x 6 = 24 units

Then, to find the area of the triangle, you can use the triangle area formula, A = [tex]\frac{1}{2}[/tex] b x h .

1/2 x 4 x 6 = 12 units

Finally, you can simply add 24 + 12 to get the total area of 36 units. Since the area is the measure found, you would use the square symbol (²) at the end of the units:

36 units²

I hope this helps!

Change the function f(x) = –2x² + 12x – 6 into vertex form.
A f(x) = -2(x – 3)2 – 24
b f(x) = -2(x - 3)2 – 6
C f(x) = -2(x - 3)2 + 12
D f(x) = -2(x – 36)2 – 30

A soccer team is taking 16 people to a match in 4 cars. The owners of the cars drive their own cars, and each takes 3 other players as passengers. In how many ways can this be done? Could you please help me with a step-by-step explanation?

Answers

Answer:

12

Step-by-step explanation:

The numbers of choices for each of B, C, D are independent of the choices the predecessors have made. It is clear where the car's owners will sit, so all we have to care about is where we put the other people. There are 16−4=12 places left in the cars, so there are 12!

there are 37,747,920,000 ways the soccer team can be taken to the match.

Let's break down the problem step by step to calculate the number of ways the soccer team can be taken to the match:

Step 1: Select the drivers for the cars.

There are 4 cars, and the owners of the cars will be the drivers. We need to choose 4 drivers from the 16 people, and this can be done using combinations. The number of ways to choose 4 drivers out of 16 is denoted as C(16, 4), which can be calculated as follows:

C(16, 4) = 16! / (4! * (16-4)!)

C(16, 4) = 16! / (4! * 12!)

C(16, 4) = (16 * 15 * 14 * 13) / (4 * 3 * 2 * 1)

C(16, 4) = 1820

There are 1820 ways to select 4 drivers for the cars.

Step 2: Assign passengers to the cars.

After selecting the drivers, each driver will take 3 other players as passengers. Since there are 3 passengers for each driver, we can calculate the number of ways to assign passengers to the cars using combinations again.

Number of ways to assign passengers to one car = C(12, 3) = 12! / (3! * (12-3)!) = 12! / (3! * 9!) = 220.

Since there are 4 cars, the total number of ways to assign passengers to the cars is 220^4 = 20,736,000.

Step 3: Combine the driver selection and passenger assignment.

To find the total number of ways the soccer team can be taken to the match, we need to multiply the number of ways to select the drivers (1820) by the number of ways to assign passengers (20,736,000):

Total number of ways = 1820 * 20,736,000 = 37,747,920,000.

So, there are 37,747,920,000 ways the soccer team can be taken to the match.

On a balance scale, five spools and three thimble balance sixteen buttons. Also, three spools balance one thimble and four buttons. How many buttons will balance one thimble?

Answers

Answer:

2 buttons

Step-by-step explanation:

Let s = spool, t = thimble, b = button

5s + 3t = 16b

3s = 1t + 4b

5s + 3t = 16b

3s - t    = 4b

       -15s - 9t = -48b

(+)      15s - 5t = 20b

If you place a 28-foot ladder against the top of a 22-foot building, how many feet will the bottom of the ladder be from the bottom of the building? Round to the nearest tenth of a foot.

Answers

Step-by-step explanation:

Pythagoras

c² = a² + b²

with c being the Hypotenuse (the side opposite of the right angle), which is in our case the ladder.

28² = 22² + b²

784 = 484 + b²

b² = 784 - 484 = 300

b (the distance of the ladder from the wall) = 17.32050808... ft ≈ 17.3 ft

Evaluate Functions From a Graph

Answers

Answer:

f(-2) = -2

Step-by-step explanation:

Start on the graph at the center, (0,0), right where the x- and y-axis cross.

The numbers on the x-axis are the x's (look left or right) The problem says to find f(-2). This means let x = -2. So skip over to the left to where x = -2, then go down until you run into the curve. You have to look at the y-axis to find the numerical answer.

Here are some other ones on this graph, to see if you can see how this works. **These two -2's are totally different. The answer -2 is not because the problem had a -2 in it.**

other examples on this graph:

f(-1) = -3

f(0) = -2

f(1) = 1

f(-3) = 1

f(-4) = 6

f(2) = 6

How many customers would the restaurant expect to still have 2 months after the review comes out?

Answers

The statement which describes what the equation tells is; The number of customers they have prior/before the review is; 500 customers.

The number of customers they have 2 months after the review is; 222.22 customers.

Exponential functions

According to the given function;

The intercept of the function represents the number of customers the restaurant has prior to the review.

This means the number of customers they have prior/before the review (at m=0) is; 500 customers.

Additionally, after 2 months of the review;

C = 500 × (2/3)^2

C = 500 × 0.44
