Answers

Answer 1

Answer:

Start by moving the decimal place in the number until you have a coefficient between 1 and 10. The number of places to the left that you had to move the decimal point is the exponent. so for example, 0.000345 would be 3.45(10)^4

What is the value of d? Assume that the line is tangent to the circle.

Answers

Answer:

121°

Step-by-step explanation:

We have been given a chord and tangent to a circle, and also a minor arc measure that is equal to 118°We know that; An angle formed by a secant and tangent of circle is half of the measure of intercepted arc.

Therefore; ∠ x = 1/2 mABC

We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.

Thus; 360° - 118° = 242°

Using the formula; ∠ x = 1/2 mABC

Then; d = 242/2

            = 121°

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.

What are parallel lines?

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.

Which of the following measurements is a little more than 3 feet? meter,centimeter,centileter, 1/4 foot

Answers

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 sum of two numbers is 52. Their product is 100. What is the answer?

Answers

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.

What is a quadratic equation?

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.

Find the surface area of the triangular prism​

Answers

Answer:

Surface Area =  267 in²   V = 162 in³

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)

                V = 162 in³

george wanted to measure the angle of a waterslide at the lake .he used a sheet of folded paper that formed 20 degree angle. he measured and found that three of the folded paper angles would fit in the angle made by the slide and the ground . what is the angle of the waterslide ?​

Answers

Final answer:

The angle of the waterslide, as measured by George using the folded paper, is 60 degrees. He found this by multiplying the paper angle of 20 degrees by the number of paper angles (3) that fit in the slide's angle.

Explanation:

The question is asking for the angle made by the waterslide and the ground. Given that a sheet of folded paper forms a 20-degree angle, and three of these paper angles fit in the angle made by the slide, we need to find the total angle.

To solve this problem, you simply multiply the angle of the paper by the number of paper angles that fit in the slide's angle. Here's how you do it:

Identify the angle of the paper, which is 20 degrees. Identify the number of paper angles fitting in the slide's angle, which is 3. Multiply these together. That is 20 degrees * 3 = 60 degrees.

So, the angle of the waterslide is 60 degrees.

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:

the graph of y=sinx is reflected on the line x=y then on y=2 the resulting graph has which equation​

Answers

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
