Answer:

18. m<EBC = 43°, m<CBD = 47°

19. m<EBC = 50°, m<ABC = 130°

Step-by-step explanation:

18. Find m<EBC and m<CBD

m<EBC = (5x + 8) and m<CBD = (6x + 5)

these two angles add up to a right angle, therefore their sum is 90°

5x + 8 + 6x + 5 = 90

11x + 13 = 90 , 11x = 77 , x = 7

m<EBC: 5(7) + 8 = 43

m<CBD: 6(7) + 5 = 47

19. Find m<EBC and m<ABC

m<EBC = (3x + 20) and m<ABC = (17x - 40)

these two angles are supplementary, meaning that they add up to 180°

3x + 20 + 17x - 40 = 180

20x - 20 = 180, 20x = 200, x = 10

m<EBC: 3(10) + 20 = 50

m<ABC: 17(10) - 40 = 130

Answer:

1. C: y = 3x - 5

2. B: y = -3x - 9

Step-by-step explanation:

1.

y = 3x + 9; (2, 1) (parallel)

                 (x₁, y₁)

y - y₁ = m(x - x₁)

y - 1 = 3(x - 2)

y - 1 = 3x - 6

   +1         +1

-------------------

y = 3x - 5

----------------------------------------------------------------------------------------------------------

2.

y = (1/3)x - 6 ; (-3, 0) (perpendicular)

                     (x₁, y₁)

y - y₁ = m(x - x₁)

y - 0 = -3(x - (-3))

y - 0 = -3(x + 3)

y - 0 = -3x - 9

   +0          +0

----------------------

y = -3x - 9

The expected area of a circular sampling region is 531.56 m²

Given,

The radius of the circular sampling region = 13m

f(r) = [tex]\left \{ {\frac{3}{4} } \atop {0}} \right.[/tex] [1 - (13 - r)²] 12 ≤ r ≤ 14

We have to find the area of the circular sampling region = E (π r²)

E (π r²) = π E (r²)

Lets find E (r²)

E (r²) =₁₂ [tex]\int\limits^[/tex]¹⁴ r² f(r) dr

= ₁₂∫¹⁴ (3r²/4) (1 - (13 -r)²) dr

=  3/4 ₁₂∫¹⁴ r² (1 - 169 - r² + 26r) dr

= 3/4 ₁₂∫¹⁴ r² (26r³ - r⁴ - 168r²) dr

= 3/4 [ 26r⁴/4 - r⁵/5 - 168r³/3]₁₂¹⁴

= 3/4 [ (26 × 14⁴)/4 - 14⁵/5 - (168 × 14³)/3] - [ (26 × 12⁴)/4 - 12⁵/5 (168 × 12³)/3]

= 3/4 [ (26 × 38416)/4 - 537824/5 - (168 × 2744)/3] - [ (26 × 20736)/4 - 248832/5 - (168 × 1728)/3]

= 3/4 [ 249704 - 107564.8 - 153664] - [ 134784 - 49766.4 - 96768]

= 3/4 [-11524.8] - [-11750.4]

= 3/4 [225.6]

= 169.2

∴ E(r²) = 169.2

Now lets find the expected area of the circular sampling region:

Area = E(π r²) =  π E (r²)

Here, E(r²) = 169.2

So, area = π × 169.2 = 531.56 m²

That is, the expected area of a circular sampling region is 531.56 m²

Our range is 0 x  10, We could also graph this with x along with the x-axis and w along the y-axis then every minute 50x gallons are gone

We have 500 gallons of the water tank and it drains at the rate of 50 gallons per minute,

.Let's suppose after 5 minutes,

W = 500 - 50 * 5W = 500 - 250W = 250

After 5 minutes, 250 gallons are left in the water tank.

Here the lowest value is 0 so our maximum time is once the tank emptied, or when w is equal to 0.

0 = 500 - 50x

50x = 500X = 500/50X = 10

So, our range is 0 x  10

The values of x when f(x) = 0 are 2 and 8

Graphs are used mostly to show the relationship between two variables (usually x and y).

The graph of y = f(x) is attached

To get the values of x when f(x) = 0 , we  consider where the line of the graph crosses the x-axis.

The graph crosses the x-axis at:

x = 2

x = 8

This means that the values of x when f(x) = 0 are 2 and 8

Therefore, in the graph of y = f(x), the values of x where f(x) = 0 are 2 and 8

By using division, if 89 members of the Taft school band spend a total of $4628 for tickets to Hammond's amusement park, The the cost of each amusement park ticket is $52

The total number of members of the Taft school = 89 members

The total cost for the ticket to Hammond's amusement park = $4628

The cost of each amusement park ticket = The total cost for the ticket to Hammond's amusement park ÷ The total number of members of the Taft school

Substitute the values in the equation

The cost of each amusement park ticket = 4628/89

= $52

Provided the owner can bring 500 lbs of crabs to sell at the weekend seafood festival, they can earn between $4,250 and $5,250, depending on which type of crabs or their different combinations.

The total earnings can be determined using mathematical operations of multiplication, division, addition, and subtraction.

The total earnings are the products (multiplication results) of the units of each type of crab and their selling prices.

The selling price of Maryland crabs per Ib = $10.50

The selling price of Alaskan crabs per lb = $8.50

The total quantity of crabs the owner can bring to the seafood festival = 500 lbs

If the owner decides to bring in Maryland crabs, they can earn $5,250 ($10.50 x 500)

If the owner decides to bring in Alaskan crabs, they can earn $4,250 ($8.50 x 500)

If the owner decides to bring a combination of Maryland and Alaskan in the ratio of 50:50, they can earn $4,750 ($10.50 x 250) + $8.50 x 250)

Thus, if the owner sells Maryland crabs, the total earnings are $5,250, but if they sell Alaskan crabs, they earn $4,250.

Step-by-step explanation:

The population of the city next year, after decreasing, will be 359,778

Here, we are given that the population of a city decreases by 1.7% per year.

This, means that the city's population will decrease by 1.7% in 1 year, (1.7 × 1.7)% in 2 years and so on.

The population of the city this year is given to be 366,000.

Thus, next year, the population will decrease by-

1.7% of 366,000

= 1.7/100 × 366,000

= 17/10 × 3,660

= 17 × 366

= 6,222

Thus, the city's total population next year will be-

366,000 - 6,222

= 3,59,778

Hence, the city's population to the nearest individual comes out to be 359,778.

By  Side - Angle - Side congruency (SAS) rule, ΔDFC is congruent to ΔAEB as shown below.

Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure.

Given is a geometrical diagram as shown in the image.

We can prove ΔDFC ≅ ΔAEB as follows -

AE = CF       [Given]

Add length EF on both sides of the equation, we get

AE = CF                                   ...[1]

∠ 1 = ∠ 2             [Given]                  ...[2]

Given is ∠ 1 = ∠ 2. Than the tangent of both angles will be same. On solving the tangent ratio, we get -

BE = FD                  ...[3]

ΔDFC ≅ ΔAEB
