Answer:

y = 4 - sin⁻¹x

Step-by-step explanation:

1. Reflection about y = x

If we reflect a function ƒ(x) about the line y = x, we are creating its inverse, ƒ'(x).

Thus, reflection of y = sinx  about y = x gives y = sin⁻¹x.

The range of the reflection extends from -∞ to +∞, but the range of the function y = sin⁻¹x is [-π/2, π/2] (see Fig. 1) .

2. Reflection about y = 2

Reflection about y = 2 retains the sign of x but changes the sign of y.

Note, however, that in Figure 2 the point at (0, 0) is reflected to (4, 0).

The function is translated up by four units.

After the two reflections, the equation of the line is

y = 4 - sin⁻¹x

Answer:

The answer is x^2+9x+8

Step-by-step explanation:

Use the foil method then combine like terms and it will already be in standard form.

Steps:

(x+1) (x+8)

x^2 + 8x + x + 8

x^2 + 9x + 8

Final answer:

To find the polynomial in standard form for (x + 1) (x + 8), multiply each term in the first binomial by each term in the second and combine like terms to get x² + 9x + 8.

Explanation:

The equation (x + 1) (x + 8) can be expanded by using the distributive property, also known as the FOIL method (First, Outer, Inner, Last), which is used to multiply two binomials. To simplify (x + 1) (x + 8), we multiply each term in the first binomial by each term in the second binomial:

Multiply the First terms: x * x = x²

Multiply the Outer terms: x * 8 = 8x

Multiply the Inner terms: 1 * x = x

Multiply the Last terms: 1 * 8 = 8

Now, we combine the like terms (8x and x):

x² + 8x + x + 8

x² + 9x + 8

The resulting expression is a polynomial in standard form. Therefore, the expanded form of (x + 1) (x + 8) is x² + 9x + 8.

Answer:

y = 3

Step-by-step explanation:

Parallel lines are lines which do not intersect. If the line is parallel to the x-axis then it is a horizontal line that intercepts the y-axis at the y-coordinate of the point (4,-3). So the equation of the line is y = b where b is the y-coordinate or y-intercept. Here it is y = 3.

Answer:

The correct answer option is: meter.

Step-by-step explanation:

We are to determine whether which of the given measurements is a little more than 3 feet.

To find that, we will use the conversion:

1 meter = 3.28084 foot

1 centimeter = 0.0328084

1/4 foot [tex] \neq [/tex] 3 foot

Keeping these values in front of us, we can clearly see that its the unit meter which is equal to a little more than 3 feet.

Final answer:

The measurement that is a little more than 3 feet is a meter, which is approximately 3.28 feet, whereas a yard is equal to 3 feet. Meters are used to measure larger objects and distances.

Explanation:

The correct answer to which measurement is a little more than 3 feet is a meter. A meter is a unit of length in the metric system, and it is used to measure larger objects or distances. One meter is approximately equal to 3.28 feet, which makes it slightly longer than a yard (3 feet).

Comparatively, a centimeter is much smaller, with 100 centimeters making up 1 meter. A ruler typically contains markings for centimeters and can also include millimeters, which are even smaller units of the metric system – there are 10 millimeters in one centimeter.

When comparing metric to customary units, a yard is the closest customary unit in length to a meter. Since there are 3 feet in a yard, and a meter is roughly 3.28 feet, a meter stick is somewhat longer than a yardstick.

Therefore, among the options provided (meter, centimeter, centileter, and 1/4 foot), the measurement that is a little more than 3 feet is a meter.

The amount of air that escapes during the first minute is 0 cubic feet.

To find out how much air escapes during the first minute, we need to evaluate the integral as per calculus,  of the rate function R(t) over the interval [0,1]. The given rate function is R(t) = 60 / (1 + t^2). Integrating this function over the interval [0,1] gives us the amount of air that escapes during the first minute.

Integrating R(t) using the power rule, we get:

Therefore, the amount of air that escapes during the first minute is 0 cubic feet.

Answer:

im positive that the answer is c because when you look at where the arcs meet to the parallel lines, if you were to make a line connecting the two points, you would have a parallel line to the transversal

-please mark as brainliest if this helped:)

Step-by-step explanation:

The corresponding angles are equal. Then the diagram which justified the parallel lines and corresponding angles is C.

When the distance between the lines is constant then the lines are called parallel lines. The lines do not intersect when they are separated from each other. And the slope of the lines is equal.

Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.

When two lines are intersected by a transversal and the corresponding angles are congruent, the lines are parallel.

Answer:

Step-by-step explanation:

The surface area consists of 3 rectangles of the sides, and the two base triangles.

The front rectangle has dimensions of 12x9, so it's area is 108 in²

The back rectangle has dimensions of 7x12, so it's are is 84 in²

The side rectangle has dimensions of 4x12, so it's area is 48 in²

The top and bottom triangles have a base of 9 and a height of 3, so their area is

A = (1/2)(9)(3) = 27/2, but there are 2 of them, so their combined area is (27/2)(2) = 27 in²

The total surface area is 108 + 84 + 48 + 27 = 267 in²

The formula for volume of a triangular prism is

V = (1/2)bhd    where b is the base of the base triangle, h is the height of the base triangle, and d is the depth of prism.

We have b = 9, h = 3, and d = 12, so the volume is

V = (1/2)(9)(3)(12)

   V = (1/2)(27)(12)

           V = (1/2)(324)

Answer:

23

Step-by-step explanation:

4c = 92

He needs to solve for c. He needs c alone on the left side. c is being multiplied by 4. The opposite operation to multiplication is division, so he needs to divide the left side by 4. The rule with equations is that you must do the same operation to both sides, so he must divide both sides of the equation by 4.

4c/4 = 92/4

c = 23

Answer: He needs 23 cans of balls.

Answer:

23

Steps:

1) Put it into a equation:

4 • C = 92

2) divide both sides:

4 divided by 4 = crosses out

92 divided by 4 = 23

3) C=23

Answer:

{2, 52}

Step-by-step explanation:

Actually, there are two answers, not just one.

Let the numbers be x and y.  

Then their sum is x + y and equals 52.

Their product is xy and equals 100.

We need to solve this system of equations for both x and y.

Solving x + y = 52 for x, we get x = 52 - y.

Substituting this result into the other equation, we get:

(52 - y)y = 100

This is a quadratic equation:  52y - y² = 100, or

-y² + 52y - 100 = 0.

Alternatively, y² - 52y + 100 = 0

Let's solve this quadratic by "completing the square."

First, identify the coefficient of the y term.  It is -52.  Take half of that, obtaining -26, square this result, obtaining 676.  Add 676 to y² - 52y, and then subtract 676 from the result:

y² - 52y + 676 - 676 + 100 = 0.

Then (y -26)² = 576.

Taking the square root of both sides, we get:

y - 26 = ± 24, or:

y = 24 + 26 = 50, and also:

y = -24 + 26 = 2

Note that 2(50) = 100, as it must, and that

2 + 50 = 52 (also correct).

The two-part answer is {2, 52}.

The numbers are 2, and 50 if the sum of two numbers is 52. Their product is 100.

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

Let x be the number the second number will be (52-x)

Their product is 100

x(52-x) = 100

52x - x² = 100

- x² + 52x - 100 = 0

After solving the quadratic equation:

x = 2, x = 50

Thus, the numbers are 2, and 50 if the sum of two numbers is 52. Their product is 100.
