The measure of angle zxy is 125 degrees.

To solve the problem, we can use the fact that the sum of the measures of two adjacent angles is 180 degrees. Let's call the measure of angle zxy "x".

We know that the ratio of m angle wxz to m angle zxy is 11:25, which means that:

m angle wxz : m angle zxy = 11 : 25

We can write this as an equation:

m angle wxz / m angle zxy = 11/25

We also know that the two angles are adjacent, so their measures add up to 180 degrees:

m angle wxz + m angle zxy = 180

Now we can use these two equations to solve for x:

m angle wxz / x = 11/25

m angle wxz = (11/25)x

Substituting this into the second equation:

(11/25)x + x = 180

(36/25)x = 180

x = (25/36) * 180

x = 125

Therefore, the measure of angle zxy is 125 degrees.

Answer:

39.27 square units

Step-by-step explanation:

In circle E with m∠DEF = 70∘ and DE=8, we want to find the area of sector DEF. To do this, we can use the formula for the area of a sector:

A_sector=1/2 r^2⋅

α

where r is the radius of the circle and α is the central angle in radians. In our case, r=8 and α=70 ∘ ⋅ π/180∘ = 7π/18 radians

Now, we can plug these values into the formula:

A_sector = 1/2(8^2) ⋅ 7π/18 = 32 ⋅ 7π/18 ≈ 39.27

So, the area of sector DEF is approximately 39.27 square units, rounded to the nearest hundredth.

The area of sector DEF in circle E is approximately 6.10 square units, rounded to the nearest hundredth.

To find the area of sector DEF in circle E, we need to use the formula for the area of a sector:

Area of sector = (Central angle / 360°) * π * r^2

where "Central angle" is the measure of angle DEF in degrees, "r" is the radius of the circle (DE in this case).

Given that m/DEF = 70° and DE = 8, we can calculate the area of sector DEF as follows:

Area of sector = (70° / 360°) * π * 8^2

Now, perform the calculations step by step:

Area of sector = (70/360) * π * 64

Area of sector = (7/36) * π * 64

Area of sector ≈ 3.14 * (7/36) * 64

Area of sector ≈ 3.14 * 1.9444

Area of sector ≈ 6.10 (rounded to two decimal places)

Therefore, the area of sector DEF in circle E is approximately 6.10 square units, rounded to the nearest hundredth.

The difference between the costs of a hovercraft and a boat in the year 2010 was approximately $1,558.

(a) The difference in costs between a hovercraft and a boat can be expressed as follows:

Cost difference = Hovercraft cost - Boat cost

Cost difference = (-1012 + 350t + 400) - (30 + 140t)

Cost difference = -1012 + 350t + 400 - 30 - 140t

Cost difference = 220t - 642

Therefore, the difference in costs between a hovercraft and a boat can be expressed as 220t - 642.

(b) To find the difference in the year 2010, we need to substitute t = 10 in the expression we derived in part (a):

Cost difference = 220t - 642

Cost difference = 220(10) - 642

Cost difference = 2200 - 642

Using the inscribed angle theorem, the value of x in the circle shown is calculated as: m<x = 36°.

According to the inscribed angle theorem an inscribed angle has an angle measure that is always half of the measure of the arc it intercepts.

Measure of arc EFG = 2(25 + 47) [inscribed angle theorem]

Measure of arc EFG = 144°

Measure of angle EHG = 1/2(m(EFG)) [inscribed angle theorem]

Substitute:

Measure of angle EHG = 1/2(144) = 72°

m<EHG = m<EGH = 72° [this is because triangle EHG is an isosceles triangle since sides EG = EH].

Therefore, we have:

m<x = 180 - 2(72)

The total area of the flag is the sum of the areas of the three stripes and the percentage of the flag that is gold is approximately 0.459%

Let's call this height "h".

We also know that the side lengths of the flag are in the ratio 2:3. This means that if the shortest side is 2x, then the longest side is 3x. Since the three stripes are of equal height, each one must be h/3 in height.

Now we can use this information to find the area of the gold-colored disk and the total area of the flag. The area of a circle is given by the formula A = πr^2, where r is the radius. Since the diameter is equal to the height of the center stripe (which is h/3), the radius of the disk is h/6. So the area of the disk is:

A_disk = π(h/6)^2 = πh^2/36

The total area of the flag is the sum of the areas of the three stripes. Since each stripe is h/3 in height and the shortest side is 2x, the area of each stripe is:

A_stripe = (2x)(h/3) = 2hx/3

So the total area of the flag is:

A_flag = 3(A_stripe) = 6hx

To find the percentage of the flag that is gold, we need to divide the area of the gold-colored disk by the total area of the flag and multiply by 100.

percentage = (A_disk / A_flag) x 100

Substituting our expressions for A_disk and A_flag, we get:

percentage = (πh^2/36) / (6hx) x 100

Simplifying, we can cancel out the factor of h and get:

percentage = (π/216)x100

So the percentage of the flag that is gold is approximately 0.459% (rounded to three decimal places).

The correct answer is ** x(y+12) or f.

We can simplify the expression 1/5x(5y+60) by multiplying the factors in the parentheses and then dividing by 5. This gives us:

```

1/5x(5y+60) = 1/5 * 5xy + 1/5 * 60x = x(y+12)

```

The equation would be written as: y = $85,000(1 + 0.12/1)^5

Then the predicted earning would be y = $132,559

y=a(b)x

where y = income

a =  $85,000

b = (1 + r = percent increase)

then x = time period = 5 years

When we put in the values we would have y = $85,000(1 + 0.12/1) ^5

The exponential function of the form y = a(b)^x is: y = $85,000(1 + 0.12/1) ^5

The value of c is 21.8.

We can solve for c by simplifying the expression on the right side of the equation and equating it to the expression on the left side.

Starting with the right side, we distribute the 3 across the parentheses:

5 * 3 * (4x - 2.6) = 60x - 13

Now, we can set this equal to the expression on the left and solve for c:

21.2x + c = 60x - 13

c = 60x - 13 - 21.2x

c = 38.8x - 13

Critical numbers: 0, -3, 3
Increasing intervals: (-∞, -3), (3, ∞)
Decreasing intervals: (-3, 0), (0, 3)

Let's analyze the given function and find the critical numbers, as well as the intervals where it is increasing or decreasing.

Function: f(x) = x^2 / (x^2 - 9)

1. Find the critical numbers:
To find the critical numbers, we need to compute the first derivative of the function and set it equal to zero or identify where it's undefined.

f'(x) = (2x(x^2 - 9) - x^2(2x)) / (x^2 - 9)^2 = (2x^3 - 18x - 2x^3) / (x^2 - 9)^2 = -18x / (x^2 - 9)^2

Setting f'(x) equal to zero:
-18x = 0
x = 0

Now, let's check where f'(x) is undefined:
x^2 - 9 = 0
x = ±3

Thus, the critical numbers are 0, -3, and 3.

2. Find the open intervals where the function is increasing or decreasing:
To determine the intervals, we will examine the sign of f'(x) in the intervals determined by the critical numbers: (-∞, -3), (-3, 0), (0, 3), (3, ∞).

Interval (-∞, -3): Choose x = -4, then f'(-4) > 0. So, f(x) is increasing on this interval.

Interval (-3, 0): Choose x = -1, then f'(-1) < 0. So, f(x) is decreasing on this interval.

Interval (0, 3): Choose x = 1, then f'(1) < 0. So, f(x) is decreasing on this interval.

Interval (3, ∞): Choose x = 4, then f'(4) > 0. So, f(x) is increasing on this interval.

Your answer:
Critical numbers: 0, -3, 3
Increasing intervals: (-∞, -3), (3, ∞)
Decreasing intervals: (-3, 0), (0, 3)

The length of the diagonal of Stacy's ceiling using the Pythagorean Theorem and trigonometry is 35.36 ft.

(a) Using the Pythagorean Theorem:

Since the ceiling is a square, we can treat it as two right triangles. Let's call the length of the diagonal 'd'. Now, we can apply the Pythagorean Theorem (a² + b² = c²) to one of the right triangles:

a² + b² = d²
25² + 25² = d²
625 + 625 = d²
1250 = d²

Now, take the square root of both sides:

√1250 = d
d ≈ 35.36 ft

(b) Using trigonometry:

In one of the right triangles, the angle between the two sides of the square (25 ft each) is 45 degrees. We can use the tangent function (tan) to relate the angle to the side lengths:

tan(45) = opposite side / adjacent side
tan(45) = 25 / 25

Since tan(45) = 1, we have 1 = 1, which confirms the angle is 45 degrees. Now, we can use the sine or cosine function to find the diagonal:

sin(45) = opposite side / hypotenuse
sin(45) = 25 / d

OR

cos(45) = adjacent side / hypotenuse
cos(45) = 25 / d

Both functions give us the same result since the angles are 45 degrees. Solving for 'd':

d = 25 / sin(45)
d ≈ 35.36 ft

So, the length of the diagonal of Stacy's ceiling is approximately 35.36 ft using both methods.
