given the function f(x)=logbase2(X), find the y-intercept of g(x) = f(x+4)+8

Answer: 39 ft2

Step-by-step explanation:

The area of the trapezoid is 39 square feet.

To find the area of a trapezoid, you can use the formula:

Area = (1/2) × (base1 + base2) × height

Given that the bases of the trapezoid are 16 feet and 10 feet, and the height is 3 feet, we can substitute these values into the formula:

Area = (1/2) × (16 + 10) × 3

Area = (1/2) × 26 × 3

Area = (1/2) × 78

Area = 39 ft^2

Therefore, the area of the trapezoid is 39 square feet.

Answer:

The volume is 423.33 cubic millimeters.

Step-by-step explanation:

The formula for volume of a cylinder is given by:

V = πr^2h, where

Step 1:  Find radius, r, of the cylinder:

The diagram shows us the diameter, d, of the circle is 7 mm.  Since the diameter is twice the radius, r, we can find r by dividing the diameter by 2:

r = d / 2

r = 7 / 2

r = 3.5 mm

Thus, the radius of the cylinder is 3.5 mm.

Step 2:  Plug in values and round to the nearest hundredth to find the volume, V, of the cylinder:

Now we can plug in 3.5 for r and 11 for h to find V, the volume of the cylinder.  We can round at the end.

V = π(3.5)^2(11)

V = π(12.25)(11)

V = 134.75π

V = 423.3296101

V = 423.33 mm^2

Thus, the volume of the cylinder is 423.33 cubic millimeters.

The sequence of transformations that maps triangle ABC onto triangle A'B'C' is a translation by (+8, -6) followed by a reflection across the y-axis.

To determine the sequence of transformations that maps triangle ABC onto triangle A'B'C', let's analyze the given coordinate points.

Triangle ABC:

A (-4, 4)

B (-8, 2)

C (-6, -6)

Triangle A'B'C':

A' (4, -2)

B' (2, 2)

C' (6, 0)

By comparing the corresponding vertices, we can identify the transformations:

Translation:

To transform A to A', we can observe that A' is obtained by moving 8 units to the right and 6 units downwards from A. Therefore, the first transformation is a translation by (+8, -6).

Reflection:

Next, we notice that B' is the reflection of B across the y-axis. Thus, the second transformation is a reflection about the y-axis.

Therefore, the sequence of transformations that maps triangle ABC onto triangle A'B'C' is a translation by (+8, -6) followed by a reflection across the y-axis.

[tex](x - 3)^2 + (y + 2)^2 = 16[/tex]

Step-by-step explanation:

The equation of a circle with a center at (h, k) and radius r is given by:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

We are given that the points G(5,-2) and H(1, −2) lie on the circle. We can use the distance formula to find the distance between these two points.

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

[tex]d = \sqrt{(5 - 1)^2 + ((-2) - (-2))^2} = \sqrt{16} = 4[/tex]

Therefore, the radius of the circle is 4.

We can now find the center of the circle by taking the average of the x-coordinates and y-coordinates of the points G and H.

[tex](h, k) = \left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}\right) = \left(\frac{5 + 1}{2}, \frac{-2 - 2}{2}\right) = (3, -2)[/tex]

Triangle FGH is inscribed in circle O, the length of radius OH is 6, and ma FGH-20. The area of the sector formed by angle FOH, in terms of pi is 6π. Hence, it is neither of the options.

Given that triangle FGH is inscribed in circle O, the length of radius OH is 6, and m∠FGH = 20.

We have to find the area of the sector formed by angle FOH, in terms of pi.

Using the central angle, we know that the measure of ∠FOH is twice that of ∠FGH, which is 40°.

Therefore, the measure of the central angle FOH is 2 * 40 = 80°.

The area of the sector formed by angle FOH, in terms of pi is given by, A = r²θ/2 where A = Area of the sector, r = radius of the circle and θ = central angle in radians.

To calculate the value of A in terms of pi, we have to convert the central angle from degrees to radians.

1 radian = 180°/π radians

Therefore, 80° = 80° * (π/180°) = 4π/9 radians.

Now we can plug in the given values of r and θ to find the area of the sector.

A = (6)² * (4π/9) / 2 = 18π/3 = 6π

Thus, the area of the sector formed by angle FOH, in terms of pi is 6π.

Hence, option 1) 2k is incorrect. Option 2) 3/2 (3) is incorrect. Option 3) 4 is incorrect. Answer: 6π.

Out of the 19 students, 10 of them passed the test and 14 students completed the assignment.

This information allows us to analyze the performance and completion rate of the students in the class.

Firstly, we can determine that there are at least 10 students who demonstrated a satisfactory level of understanding and knowledge in the subject matter, as they successfully passed the test.

The sum of Ethan and Calvin's current ages is approximately 45.65.

Let's assume Ethan's current age is represented by 'E', and Calvin's current age is represented by 'C'.

From the given information, we can establish the following equations:

The product of their current ages is 238:

E × C = 238

The product of their ages after four years is 378:

(E + 4) × (C + 4) = 378

We can solve this system of equations to determine the values of E and C, and then calculate their sum.

From equation 1, we can express E in terms of C:

E = 238 / C

Substituting this value of E into equation 2:

(238 / C + 4) × (C + 4) = 378

Expanding and simplifying the equation:

(238 + 4C) × (C + 4) = 378

[tex]238C + 952 + 4C^2 + 16C - 378 = 0\\4C^2 + 254C + 574 = 0[/tex]

Now, we can solve this quadratic equation for C using the quadratic formula:

C = (-b ± √(b^2 - 4ac)) / (2a)

Plugging in the values:

a = 4, b = 254, c = 574

C = (-254 ± √([tex]254^2[/tex]- 4 × 4 × 574)) / (2× 4)

After solving, we find two possible values for C: C ≈ -73.85 and C ≈ -39.65

Since age cannot be negative, we discard the negative value. Thus, C ≈ 39.65.

Plugging this value of C back into equation 1:

E × 39.65 = 238

E ≈ 238 / 39.65

E ≈ 6

Therefore, Ethan's current age (E) is approximately 6 and Calvin's current age (C) is approximately 39.65.

The sum of their current ages is:

6 + 39.65 ≈ 45.65

Hence, the sum of Ethan and Calvin's current ages is approximately 45.65.

The required angle is 24.5°.

Given is a right triangle with perpendicular side 16 and the base = 35 we need to find an acute angle in it,

To find the acute angle in a right triangle given the lengths of the perpendicular side and the base, you can use the tangent function.

The tangent of an angle is defined as the ratio of the length of the perpendicular side to the length of the base side.

In this case, the perpendicular side is 16 and the base is 35.

Let's denote the acute angle as θ.

Using the tangent function, we can set up the equation:

tan(θ) = perpendicular side / base

tan(θ) = 16 / 35

To find the value of θ, we can take the inverse tangent of both sides:

θ = tan⁻¹(16 / 35)

θ = 24.5°

Hence the required angle is 24.5°.

Step-by-step explanation:

To solve this problem, we need to find the circumference of the circular playground and then multiply it by the number of rounds the runner completes.

The circumference of a circle can be calculated using the formula:

Circumference = 2 * π * radius

Given that the radius of the playground is 77m, we can substitute this value into the formula to find the circumference:

Circumference = 2 * π * 77

Now, we need to calculate the distance covered by the runner in 5 complete rounds. Since one round is equal to the circumference, the distance covered in 5 rounds would be:

Distance = 5 * Circumference

Substituting the value of the circumference, we have:

Distance = 5 * (2 * π * 77)

To simplify, we can use an approximation of π as 3.14:

Distance ≈ 5 * (2 * 3.14 * 77)

Calculating further:

Distance ≈ 5 * (6.28 * 77)

Distance ≈ 5 * 483.56

Distance ≈ 2417.8

Therefore, the distance covered by the runner in 5 complete rounds around the circular playground is approximately 2417.8 meters, which can be rounded to 2420 meters (as given in the answer).

Hope this helps!

Answer:

2420

Step-by-step explanation:

Circumference = 2πr

One complete round will be equal to the circumference = 2πr

Five rounds will be five times the circumference
