What statement represents the reasonable time when the basketball is in the air

Answer:

48

Step-by-step explanation:

central angle with arc of <y is 96

so circumference angle 48

Answer:

y = 48°

Step-by-step explanation:

The angle on the circle ( the inscribed angle ) y is half of the central angle subtended by the same arc on the circle, hence

y = 0.5 × 96° = 48°

Answer:

Both expressions are equivalent to 78 when t = 6 ⇒ answer A

Step-by-step explanation:

* To solve this problem substitute the value of t and then check

  the answer

∵ The first expression is 2(7t - 3) ⇒ simplify it

# 2(7t) = 14t

# 2(3) = 6

∴ 2(7t - 3) = 14t - 6

- Substitute t by 4

∴ 14t - 6 = 14(4) - 6 = 56 - 6 = 50

- Substitute t by 6

∴ 14t - 6 = 14(6) - 6 = 84 - 6 = 78

∵ The second expression is 15t - 12

- Substitute t by 4

∴ 15t - 12 = 15(4) - 12 = 60 - 12 = 48

- Substitute t by 6

∴ 15t - 12 = 15(6) - 12 = 90 - 12 = 78

- The first expression has two values

# 50 when t = 4

# 78 when t = 6

- The second expression has two values

# 48 when t = 4

# 78 when t = 6

- From these information

# The two expressions have the same value 78 when t = 6

∴ Both expressions are equivalent to 78 when t = 6

Answer:

Step-by-step explanation:

Here y = -x^2 + 36.

We can choose x values pretty much at random and then calculate the associated y values:

x    y = -x^2 + 36

----  --------------------

0                      36

2                 -2^2 + 36 =  32

-2                  -4 + 36 = 32

3                  -9 + 36 = 27

You did not share the equation of the slanted line.  Let's assume that the equation of this line is y = mx + b.  The first two points in the table above are (0, 36) and (2, 32).  We could find the equation of this line as follows:

Slope:  as we move from (0, 36) to (2, 32), x increases by 2 and y decreases by 4.  Thus, the slope is m = rise / run = -4/2, or -2.  Using info from the point (0, 36), we find the y-intercept of this straight line:

y = mx + b becomes 36 = m(0) + b, so b = 36, and the line is y = -2x + 36.

We need to find the points of intersection of y = -2x + 36 and y = -x^2 + 36.  We can equate these equations to eliminate y:  -2x + 36 = -x^2 + 36, or

-2x = -x^2.  Equivalently, 2x - x^2 = 0, or (x)(2 - x) = 0.  Then x = 0 and x = 2.

This says that the line and the parabola intersect in at least two places:

(0, 36) and (2, 32).

Answer:

x= 36.2

Step-by-step explanation:

Because that's a right triangle and the reference angle and adjacent side measures are given to us, we can use the trig ratio for cosine.  Cosine relates the side adjacent to (next to...NOT ever the hypotenuse!) the angle to the hypotenuse.  Therefore, our equation will look like this:

[tex]cos(28)=\frac{32}{x}[/tex]

Solving for x we have

[tex]x=\frac{32}{cos(28)}[/tex]

Perform that operation on your calculator in degree mode and you'll get that the length of the hypotenuse is 36.2.  If for some reason, your math gave you the length of the hypotenuse and it was shorter than one of the other sides, you did something wrong.  The hypotenuse will ALWAYS be the longest side in a right triangle.

Final answer:

The domain of f(x) = (1/6)x + 2 is all real numbers and the range is y > 2.

Explanation:

The domain of the function f(x) = (1/6)x + 2 is {x | x is a real number} because there are no restrictions on the input values. The range of the function is {y | y > 2} because any value of x will give a y-value greater than 2. To find the range, you can consider that the slope of the function is positive, meaning that as x increases, y will also increase, but it will never go below 2.

The area of the scale drawing of Charlene's swimming pool is [tex]\( 67.5} \)[/tex] square feet.

To find the area of the scale drawing of Charlene's swimming pool, we need to understand the scale given and how it applies to the dimensions and area.

Given:

Actual area of the swimming pool: [tex]\( 120 \) ft\(^2\)[/tex]

Scale of the drawing: [tex]\( 1 \frac{1}{2} \) centimeters = 2 feet[/tex]

First, convert the scale to centimeters:

[tex]\[ 1 \frac{1}{2} \text{ centimeters} = 1.5 \text{ centimeters} \][/tex]

Now, determine the scale factor for the dimensions:

[tex]\[ \text{Scale factor} = \frac{1.5 \text{ cm}}{2 \text{ ft}} \][/tex]

To find the area of the scale drawing, we need to square the scale factor, because area is two-dimensional:

[tex]\[ \text{Area scale factor} = \left(\frac{1.5}{2}\right)^2 \][/tex]

[tex]\[ \text{Area scale factor} = \left(0.75\right)^2 \][/tex]

[tex]\[ \text{Area scale factor} = 0.5625 \][/tex]

Now, calculate the area of the scale drawing:

[tex]\[ \text{Area of scale drawing} = 0.5625 \times 120 \text{ ft}^2 \][/tex]

[tex]\[ \text{Area of scale drawing} = 67.5 \text{ ft}^2 \][/tex]

Answer:

No, the ladder will not be save at the height 16.5 feet from the ground

She must to buy 9 rolls to have enough crepe papers to decorate her ceiling

Step-by-step explanation:

* Lets change the story problem to mathematics information

- The ladder , the wall and the ground formed together a right

  angle triangle

- The wall and the ground are perpendicular to each other

- The length of the ladder is the hypotenuse of the triangle

- The vertical height of the ladder is the vertical leg of the triangle

- The horizontal distance between the ladder and the vertical wall

 on the ground is the horizontal leg of the triangle

* Lets revise the trigonometry functions

- In any right angle triangle:

# The side opposite to the right angle is called the hypotenuse

# The other two sides are called the legs of the right angle

* If the name of the triangle is ABC, where B is the right angle

∴ The hypotenuse is AC

∴ AB and BC are the legs of the right angle

- ∠A and ∠C are two acute angles

- For angle A

# sin(A) = opposite/hypotenuse

∵ The opposite to ∠A is BC

∵ The hypotenuse is AC

∴ sin(A) = BC/AC

# cos(A) = adjacent/hypotenuse

∵ The adjacent to ∠A is AB

∵ The hypotenuse is AC

∴ cos(A) = AB/AC  

# tan(A) = opposite/adjacent

∵ The opposite to ∠A is BC

∵ The adjacent to ∠A is AB

∴ tan(A) = BC/AB

* Lets solve the problem

- We need to calculate the measure of the angle between the

  ladder and the ground, let it called Ф

- The vertical height is the opposite to this angle Ф

- The hypotenuse is the length of the ladder

∵ We have the opposite and the hypotenuse, we can use

  the sin function

∵ sin(Ф) = opposite/hypotenuse

∵ The opposite is the vertical height = 16.5 feet

∵ The hypotenuse is the length of the ladder = 17 feet

∴ sin(Ф) = 16.5/17

∴ Ф = [tex]sin^{-1}\frac{16.5}{17}=76.1[/tex] dgree

- The ladder will be save if the angle between the ladder and

 the ground is no more than 70°

∵ The angle between the ladder and the ground is 76.1°

∴ Its measure is greater than 70°

* The ladder will not be save at the height 16.5 feet from the ground

* Lets study the information in the problem

- Katie wants to put the crepe paper around the perimeter of the

 ceiling which shaped a square of side length 12 feet

- And also from each corner to the opposite corner

- She needs the length of the 4 sides of the square and the length

 of its 2 diagonals

* Lets find the length of the diagonal of the square

∵ The two adjacent sides of the square formed two legs of a right

   angle triangle and the diagonal joining the endpoints of the legs

  is the hypotenuse of the triangle

- Use Pythagoras theorem to find the length of the diagonal

∴ The length of the diagonal = √(s² + s²) √(2s²) = s√2

∵ The length of the side of the square = 12 feet

∴ The length of the diagonal = 12√2

* Now lets find the length of the crepe papers she needs

∵ She needs the length of the 4 sides of the square and the length

  of its 2 diagonals

∴ The length of crepe papers = 12 + 12 + 12 + 12 + 12√2 + 12√2 = 81.94 feet

∵ Each roll of the crepe papers contain 10 feet

- To find the number of rolls divide the length of the crepe papers by 10

∴ The number of rolls = 81.94 ÷ 10 = 8.194

* She must to buy 9 rolls to have enough crepe papers to decorate

 her ceiling

* V.I.N:

- If she decide to buy 8 rolls, some part of ceiling will not decorate

 because the 8 rolls have 80 feet only and she needs 81.94 feet

Answer:

The measures of the angles of the rhombus are 72° , 108° , 72° , 108°

Step-by-step explanation:

* Lets revise the properties of the rhombus

- It has 4 equal sides

- Each two opposite angles are equal

- Each two adjacent angles are supplementary (their sum = 180°)

- The diagonals are perpendicular to each other

- The diagonals bisect the vertices angles (divide each vertex into two

 equal parts)

* Now lets solve the problem

- Let the name of the rhombus is ABCD

- The two diagonals are AC and BD

- Let the diagonals AC and BD make the angles BAC and ABD with

 side AB

∵ The diagonals of the rhombus bisect the vertex angles

∴ m∠BAC is half m∠A

∴ m∠ABD is half m∠B

- There is a ratio between the measures of the angles BAC and ABD

∵ m∠BAC : m∠ABD = 6 : 9

∵ m∠A + m∠B = 180° ⇒ consecutive angles

∴ m∠BAC + m∠ABD = 1/2 × 180° = 90°

∵ m∠BAC : m∠ABD : their sum

         6     :       9      : 15⇒(6 + 9)

          ?    :        ?      : 90° ⇒(the sum of the angles)

∴ m∠BAC = 6/15 × 90° = 36°

∴ m∠ABD = 9/15 × 90° = 54°

∵ m∠BAC is half m∠A

∴ m∠A = 36° × 2 = 72°

∵ m∠ABD is half m∠B

∴ m∠B = 54° × 2 = 108°

* The measures of the angles of the rhombus are 72° , 108° , 72° , 108°

Answer:

72°, 108°, 72°, and 108°

Answer:

Step-by-step explanation:

True

7 X 9 X 6 = 378

Answer:

First option: True.

Step-by-step explanation:

To know if the volume of this rectangular prism is 378 m³, you need to use the formula for calculate the volume of a rectangular prism:

[tex]V=lwh[/tex]

Where "l" is the lenght, "w" is the width and "h" is the height.

You know that that this rectangular prism measures 7 meters long, 9 meters wide, and 6 meters high, then you can substitute these values into the formula.

Therefore, the volume of the rectangular prism is:

[tex]V=(7m)(9m)(6m)\\V=378m^3[/tex]

Then the answer is: True.

Answer:

D. 3

Step-by-step explanation:

If the prisms are said to the similar, that means that the ratio/relation between their corresponding sides have to equal, so

[tex]\frac{x}{1} = \frac{9}{3} = \frac{30}{10}[/tex]

We can easily use the part x/1 = 9/3 to make a cross-multiplication that would give us:

x = (1 * 9) / 3 = 9/3 = 3

So, the green prism is a dilated version of the blue one by a dilation/scale factor of 3.

As a math teacher, I would guide you through solving the problem of finding the value of \( x \) for two similar prisms. However, without specific information about the measurements of the prisms, we can't calculate this value. Similarity in prisms implies that corresponding lengths are proportional, but without knowing these lengths or their ratios, we can't determine \( x \).
However, let's assume you have provided the dimensions for both prisms. For similar prisms, the ratio of any two corresponding linear measurements (such as the height, width, or depth) is the same. If we were given that the ratio of a pair of corresponding dimensions is 1:3, for example, then all other pairs of corresponding dimensions would also have a 1:3 ratio.
Here's a typical process to follow if you had the dimenions:
1. Determine the ratio of corresponding lengths:
Suppose for the smaller prism, a certain length is given as 'a', and for the corresponding length on the larger prism, the length is given as '3a' (implying a 1:3 ratio for the sides).
2. Apply the ratio to unknown lengths:
If 'x' is an unknown length on the larger prism and its corresponding length on the smaller prism is given as some value 'b', then we set up the proportion \( \frac{b}{x} = \frac{1}{3} \).
3. Solve for 'x':
To find 'x', you would solve the proportion by cross-multiplying and dividing as necessary, \( x = 3b \).
However, since we don't have actual numbers here, we can't follow these steps. To answer this question, I would need specific lengths for the corresponding sides of the prisms. Once provided, I can demonstrate the mathematical process to find \( x \). For now, there is not enough information to solve for \( x \), and none of the options A, B, C, or D can be verified as correct.
