Answer:

15.5 in

Step-by-step explanation:

Use property of secant and tangent segments in the circle:

If one secant and one tangent are drawn to a circle from one exterior point, then the square of the length of the tangent is equal to the product of the external secant segment and the total length of the secant.

In your case,

Tanget - x in

External secant - 10 in

Total secant - 10+14 in

So,

[tex]x^2=10\cdot (10+14)\\ \\x^2 =10\cdot 24\\ \\x^2 =240\\ \\x\approx 15.5\ in[/tex]

Answer:

You add them together and divide it by how many number there are.

Step-by-step explanation:

For example lets say we need to find the average of 12, 15, 18, and 24.

You would do 12+15+18+24

You will get a sum of 69

Then since there are 4 numbers you do 69 divided by 4 and get a quotients of 17.25.

Therefore 17.25 is the average of all four numbers.

The total number of seats in all 7 rows is 24

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that  there are 16 rows and each row has either 20 or 24 seats.

Therefore,

7 x 24 = 168

9 x 20 = 180

If the total number of seats in all 16 rows is 348,

168 + 180 = 348

Answer:

2000 m/h

Step-by-step explanation:

speed = distance/time

Mila's distance was (2/3)·(750 m) = 500 m, so her speed was ...

(500 m)/(1/4 h) = 2000 m/h

Mila swam 500 meters in 0.25 hours. Hence, her average speed was 2000 meters/hour.

To calculate Mila's average speed, first we need to calculate the distance she swam. Mila swam 2/3 of Logan's distance, which is 2/3 * 750 meters = 500 meters.

Now, we need to find out how long she swam in hours as her time was given in quarters of an hour. As Mila swam for 1/4 of an hour, this translates to 1/4 * 60 minutes = 15 minutes, or 0.25 in hours.

Speed is calculated as distance/time, therefore Mila's average speed is 500 meters/0.25 hours = 2000 meters/hour.

Answer: Option C

Step-by-step explanation:

By definition, a relation is considered a function if and only if for each input value x there is only one associated output y value.

To verify if the graph of a relation is a function, trace on the graph vertical lines parallel to the y axis. If one of these vertical lines cuts the graph in 2 or more points, then the relationship is not a function

By definition, a function is considered a one-to-one function if and only if there is no equal output value and, for two different input values.

For example, the following ordered pairs do not correspond to a one-to-one function, because the output value y = 6 is associated with two input values ​​x = 1 and x = 3

(1, 6) (3, 6)

To verify if the graph of a relation is a function, draw on the graph horizontal lines parallel to the x axis. If one of these horizontal lines cuts the graph in 2 or more points, then the relationship is not a one-to-one function.

When you draw vertical lines on the plot shown, you will see that they always intersect at a single point. Therefore the relationship is a function

When drawing horizontal lines on the displayed graph you will notice that they always intersect at a single point. Therefore the function is a one-to-one function

the answer is C

Check the picture below.

[tex]\sqrt[6]{200}[/tex]

Step-by-step explanation:

First of all, you need to know that you cannot multiply those radicals without having a common index (the little number outside the radical that sits in the curve of the radical).  One is a 3 and the other, without being stated outright, is understood to be a 2.  BUT we can make them like.  The index of a radical is the denominator of the exponential equivalent.  

[tex]\sqrt[3]{5}=5^{\frac{1}{3}}[/tex] and

[tex]\sqrt{2}=2^{\frac{1}{2}}[/tex]

See how the indexes are now the denominators of the rational exponents.  We can make them like by finding the LCM of 3 and 2...which is 6:

[tex]5^{\frac{1}{3}}=5^{\frac{2}{6}}[/tex] and

[tex]2^{\frac{1}{2}}= 2^{\frac{3}{6}}[/tex]

Now that the indexes are like, we rewrite them as radicals again:

[tex]\sqrt[6]{5^2}*\sqrt[6]{2^3}[/tex] which, simplified, is

[tex]\sqrt[6]{25}*\sqrt[6]{8}[/tex]

Now we can find the product which is

[tex]\sqrt[6]{200}[/tex]

The product of ∛5 ×√2 is approximately 2.41. The correct option is b) [tex]\sqrt[6]{200}[/tex], which matches the calculated value.

To find the product ∛5 × √2, we first take the cube root of 5 (∛5) and then multiply it by the square root of 2 (√2).

∛5 ≈ 1.71 (approximately, rounded to two decimal places)

√2 ≈ 1.41 (approximately, rounded to two decimal places)

Now, let's calculate the product:

∛5 × √2 ≈ 1.71 × 1.41 ≈ 2.41 (approximately, rounded to two decimal places)

Now, let's check the options:

a. [tex]\sqrt[6]{10}[/tex] ≈ 1.72 (approximately, rounded to two decimal places)

b. [tex]\sqrt[6]{200}[/tex] ≈ 2.41 (approximately, rounded to two decimal places) <-- Matches our calculated value.

Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.

Answer:

b = √(c^2 - a²)

Step-by-step explanation:

Start with the given c = √a^2 + b^2.  Squaring both sides, we get:

c² = a² + b².

We want to iosolate b² and then b.

So:  subtract a² from both sides, resulting in:

c² - a² = b²

Taking the square root of both sides, we get:

√b² = √(c² - a²)

and so:

b = √(c^2 - a²)

To solve the Pythagorean theorem equation for b, isolate b on one side by first squaring both sides. Move the a^2 term to the other side of the equation, then take the square root of both to solve for b. The solution is b = √(c^2 - a^2).

The formula mentioned, c = √a^2 + b^2, represents the application of the Pythagorean theorem for right-angled triangles. To solve this equation for b, you would have to isolate b on one side. Start by squaring both sides of the equation, which gives: c^2 = a^2 + b^2. Then, move a^2 to the other side of the equation to isolate b^2 assuming c^2 > a^2. This gives you: b^2 = c^2 - a^2. Then, take the square root of both sides, which gives: b = √(c^2 - a^2).

Answer:

  the last choice shown here: F'(0, -4), G'(-3, -1), H'(-2, 2), I'(0, -2)

Step-by-step explanation:

The translation vector tells you that the new coordinates are found by adding -4 to each of the old coordinates. When you realize that the answer choices differ in their values for H' and I', you can conclude that you only need to find one of those to determine the correct answer.

  H' = H + (-4, -4) = (2-4, 6-4) = (-2, 2) . . . corresponds to the last choice shown

_____

When you subtract 4 from each of the coordinates of the other points, you find they also match the last answer selection.

Final answer:

The translation of the figure along the vector ⟨−4,−4⟩ results in the vertices F'(0,-4), G'(-3,-1), H'(-2,2), and I'(0,-2).

Explanation:

The student is asking about a translation of a geometric figure in the coordinate plane. To translate a figure, we add the translation vector to each vertex of the figure. In this case, the translation vector is ⟨−4,−4⟩, which means we subtract 4 from the x-coordinate and subtract 4 from the y-coordinate of each vertex of the figure.

Therefore, the translated figure will have vertices F'(0,-4), G'(-3,-1), H'(-2,2), and I'(0,-2).

The value of slope m = -1

Step-by-step explanation:

x = -2 + 4t

and y = 1 + 4t

Solving the both equations

x +2 = 4t

=> t = (x+2)/4     eq(1)

y-1 = 4t

=> t = (y-1)/4      eq(2)

Putting eq(1) = eq(2) as left hand side of both equations are same

(x+2)/4 = (y-1)/4

Cross multiplying

4(x+2) = 4(y-1)

4x + 8 = 4y -4

4x +4y = -4 -8

4x + 4y = -12

4(x+y) = -12

x+y = -12/4

x+y = -3

y = -x -3

The slope intercept form of line is:

y = mx + b

where m is the slope. Comparing with y = -x-3

The value of slope m = -1

The slope of the line defined by the parametric equations x=-2+4t and y=1+4t is mathematically given as

m = -1

Step-by-step explanation:

Given

8r² - 16r - 10 ← factor out 2 from each term

= 2(4r² - 8r - 5)

To factorise the quadratic

Consider the factors of the product of the coefficient of the r² term and the constant term which sum to give the coefficient of the r- term.

product = 4 × - 5 = - 20 and sum = - 8

The factors are + 2 and - 10

Use these factors to split the r- term

4r² + 2r - 10r - 5 ( factor the first/second and third/fourth terms )

= 2r(2r + 1) - 5(2r + 1) ← factor out (2r + 1) from each term

= (2r + 1)(2r - 5), so

4r² - 8r - 5 = (2r + 1)(2r - 5) and

8r² - 16r - 10 = 2(2r + 1)(2r - 5) ← in factored form

The factored form of the given quadratic equation 8r² - 16r - 10 will be 2(2r + 1)(2r - 5) .

A quadratic equation is the second-order degree algebraic expression in a variable.

The standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

It is Given that

8r² - 16r - 10

= 2(4r² - 8r - 5)
