What are the coordinates of the image of the point (-9,4) after a 90 degree clockwise rotation followed by a translation 3 units right?​

It will take the baseball is 0.64 seconds to hit the ground

From the question, we have the following parameters that can be used in our computation:

Initial height = 4 feet

Initial velocity = 4 feet per seconds

So, the function is given as

h = −16t^2 + 4t + 4

When it hits the ground, we have

h = 0

So, we have

−16t^2 + 4t + 4 = 0

Divide through by 4

So, we have

-4t^2 + t + 1 = 0

Using a graphing tool, we have

t = 0.64

Hence, the time is 0.64 seconds

Since line segment MN is congruent to line segment PQ, the value of x is equal to 7.

In Mathematics and Geometry, the chord of a circle can be defined as a line segment that typically join any two (2) points on a circle. This ultimately implies that, a chord simply refers to the section of the line that is used for connecting two (2) separate points on a circle.

In this context, we can reasonably infer and logically deduce that line segment MN is congruent to line segment PQ;

7x + 13 = 10x - 8

10x - 7x = 13 + 8

3x = 21

x = 21/3

Answer:

21) 130

24) 150

Step-by-step explanation:

21)

m<BAC = 50

m<BAO = m<CAO = (1/2)m<BAC = (1/2)(50) = 25

A radius intersects a tangent at a right angle, so m<B = 90.

m<BAO + m<B + m<AOB = 180

25 + 90 + m<AOB = 180

m<AOB = 65

m<BOC = 2 × m<AOB = 2 × 65 = 130

22)

m<BAC = 34

m<BAO = m<CAO = (1/2)m<BAC = (1/2)(34) = 17

A radius intersects a tangent at a right angle, so m<B = 90.

m<BAO + m<B + m<AOB = 180

17 + 90 + m<AOB = 180

m<AOB = 73

m<BOC = 2 × m<AOB = 2 × 73 = 146

23)

m<AOB = (1/2)m<BOC = (1/2) × 67 = 33.5

m<BAO + m<B + m<AOB = 180

m<BAO + 90 + 33.5 = 180

m<BAO = 56.5

m<BAC = 2 × m<BAO = 2 × 56.5 = 113

24)

m<AOB = (1/2)m<BOC = (1/2) × 30 = 15

m<BAO + m<B + m<AOB = 180

m<BAO + 90 + 15 = 180

m<BAO = 75

m<BAC = 2 × m<BAO = 2 × 75 = 150

Using the compound interest formula, the time it takes the investment to double is 0.68 years

To find the time it takes the investment to double, we use the compound interest formula.

A = P(1 + r)ⁿ where

So, making n subject of the formula, we have that

n = ㏑(A/P)/(1 + r)

Since we want to find the time it takes the investment to double, we have that

So, substituting the values of the variables into the equation, we have that

n = ㏑(A/P)/(1 + r)

n = ㏑(2P/P)/(1 + 0.0133)

n = ㏑(2)/(1.0133)

n = 0.693/1.0133

n = 0.68 years

If the cylindrical-barrel has volume of 785.4 ft³, then the radius of the barrel is 5 ft, option(c) is correct.

We know that volume of cylindrical barrel is given by formula : V = πr²h

where V denotes volume, r denotes radius, and h denotes height of the cylinder.

In this case, we are given that the volume of the barrel is 785.4 ft³ and the height is 10 ft.

Substituting these values and taking π ≈ 3.14, into the Volume-formula,

We get,

785.4 = 3.14 × r² × (10);

Simplifying this equation,

We get,

The equation of the circle from the given graph is (x + 2)² + (y - 2)² = 9.

The definition of a circle as a two-dimensional geometric shape is a closed curve with all points equally spaced from the centre, which is a fixed point. The radius of a circle is the separation between its centre and any point at its periphery. A circle is a form of ellipse with an equal length main and minor axis and no corners or edges. The design of wheels, gears, and circular buildings like domes and arches are just a few examples of how circles are used frequently in daily life. Circles also play a significant role in geometry, mathematics, and science.

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

(x - h)² + (y - k)² = r²

Now, for the given center (-2, 2) we have:

(x - (-2))² + (y - 2)² = r²

(x + 2)² + (y - 2)² = r²

Answer:

45,971 books

Step-by-step explanation:

The library had 32,765 books this year. 1,578 books were ruined and 14,784 new books were purchased. To calculate the number of books in the library now, we need to subtract the number of ruined books from the original number of books and then add the number of new books purchased. Therefore, the number of books in the library now is:

32,765 - 1,578 + 14,784 = 45,971

Before we can solve this question we need to create an expression to calculate 150$ discounted of 30%. The expression would be,

[tex]\text{T}=150\times(1-\text{r})[/tex]

Where:

Before we can use the formula we need to get the percent in decimal form by moving the decimal two digits to the left. Once we have that we can plug the values in the formula and solve for T.

30%   ⇔   0.30

[tex]\text{T}=150\times(1-\text{r})[/tex]

[tex]\text{T}=150\times(1-0.30)[/tex]

The value of x in the intersected chord is 103 degrees.

The angles of intersecting chords theorem states that If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.

Therefore,

62 = 1 / 2 (x + 21)

62 = 0.5x + 10.5

subtract 10.5 from both sides of the equation

62  - 10.5 = 0.5x + 10.5 - 10.5

0.5x = 51.5

Answer:

Where the above data and or function are given, note that the missing value in the table is 7.768

The table is reconstructed as follows:

x        y

4        6.4

4.3     6.88

4.8       ?

5.2       8.32

Thus, merely taking a look at the values of x, a pattern is established.

We can see that x is increasing by 0.5.

To derive the missing value of y given x, we have to

1) compute the difference int he values of y for each respective x

we can say

y(5.2) - y(4.3) = 8.32 - 6.88 = 1.44

To find the value of y for x = 4.8:

y(4.8) = y(4.3) + (0.5/0.9) * (y(5.2) - y(4.3))

⇒ y(4.8) = 6.88 + (0.5/0.9) * 1.44

y (4.8) = 7.68

The length of the interior diagonal of the rectangular prism is approximately 141.4 centimeters.

To find the length of the interior diagonal of the rectangular prism, we need to use the Pythagorean theorem. The interior diagonal of the rectangular prism is the hypotenuse of a right triangle with legs equal to the length and width of the base and height of the rectangular prism.

Let's label the length, width, and height of the rectangular prism as l, w, and h, respectively. Then, the interior diagonal d can be found using the Pythagorean theorem as:

d² = l² + w² + h²

Substituting the given values, we get:

d² = 60² + 80² + 100²

Simplifying the expression:

d² = 3600 + 6400 + 10000

Answer:

Let b = number of boys and g = number of girls.

g/b = 5/3, so g = (5/3)b

b + g = 136

b + (5/3)b = 136

(8/3)b = 136, so b = 136(3/8) = 51 boys, and g = 85 girls

There are 51 boys and 85 girls at the volleyball summer camp.

The ratio of boys to girls at the camp is 3 to 5. By applying this ratio to the total number of children at the camp (136), we find that there are 51 boys and 85 girls.

The question tells us that for every 3 boys at a camp, there are 5 girls. This means that the ratio of boys to girls is 3:5. This ratio tells us that out of every 8 (3+5) children, 3 are boys and 5 are girls.

Now it's mentioned there are 136 children in total. We divide total children by sum of the ratio to find out the number of boys and girls. 136 divided by 8 equals 17. This means there are 17 sets of 'every 8 children'.

To find the number of boys, multiply 3 (number of boys in one set) by 17 (total sets) and we get 51 boys. Using the same process for the girls, we multiply 5 (number of girls in one set) by 17 (total sets), resulting in 85 girls. Thus, among the 136 children at the camp, there are 51 boys and 85 girls.

It would take about 2.6 years for the value of the account to reach $5,920, assuming no deposits or withdrawals are made.

We can use the formula for compound interest to solve the problem;

A = [tex]P(1+r/n)^{(nt)}[/tex]

where;

A is the amount after t years

P is principal (the initial amount invested)

r is annual interest rate (as a decimal)

n is number of times the interest is compounded per year

t is the time in years

In this case, we know that;

P = $4,900

r = 0.03 (3% expressed as a decimal)

n = 12 (interest is compounded monthly)

A = $5,920

We can solve for t by plugging in these values and solving for t;

$5,920 = $4,900[tex](1+0.03/12)^{12t}[/tex]

Divide both sides by $4,900;

1.20918367347 = [tex](1+0.03/12)^{12t}[/tex]

Take the natural logarithm of both sides;

ln(1.20918367347) = ln([tex](1+0.03/12)^{12t}[/tex])

Use the property of logarithms that allows us to bring the exponent down;

ln(1.20918367347) = 12t ln(1 + 0.03/12)

Divide both sides by 12 ln(1 + 0.03/12)

t = ln(1.20918367347) / (12 ln(1 + 0.03/12))

t ≈ 2.6 years
