The value x in the secant line using the Intersecting theorem is 4.

Intersecting secants theorem states that " If two secant line segments are drawn to a circle from an exterior point, then the product of the measures of one of secant line segment and its external secant line segment is the same or equal to the product of the measures of the other secant line segment and its external line secant segment.

From the figure:

First sectant line segment = ( x - 1 ) + 5

External line segment of the first secant line = 5

Second sectant line segment = ( x + 2 ) + 4

External line segment of the second secant line = 4

Using the Intersecting secants theorem:

5( ( x - 1 ) + 5 ) = 4( ( x + 2 ) + 4 )

Solve for x:

5( x - 1 + 5 ) = 4( x + 2 + 4 )

5( x + 4 ) = 4( x + 6 )

5x + 20 = 4x + 24

5x - 4x = 24 - 20

x = 4

Therefore, the value of x is 4.

Option C) 4 is the correct answer.

x = -12/2

x = -6

Therefore, 4 = -2x - 8

2x = -8 - 4

2x = -12

x = -12/2 = -6

Therefore, A is correct.

E. 2x + 4 = -8

2x = -8 - 4

2x = -12

x = -12/2

x = -6

Answer:

  499.338 feet

Step-by-step explanation:

You want to know the distance traveled by an object in 25 seconds when its velocity is described by 20+5cos(t) feet per second.

The distance an object travels is the integral of its velocity. For the given velocity and time period, the distance is ...

  \(\displaystyle d=\int_0^{25}{v(t)}\,dt=\int_0^{25}{(20+5\cos(t))}\,dt=(20t+5\sin(t))|_0^{25}\\\\d=500+5\sin(25)\approx\boxed{499.338\quad\text{feet}}\)

The distance traveled in 25 seconds is 499.33 feet.

It is required to find the distance traveled in 25 seconds.

The distance of an object can be defined as the complete path travelled by an object .Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.

Given:

We have to find the distance , we will integrate v(t) from 0 to 25 second.

Consider an object traveling at constant velocity v = k. Then, each second, it travels k feet, so after t seconds, the distance traveled is k*t.

Now, suppose its speed increases by 1 feet/sec . So, estimate for distance traveled after t seconds is

1 + 2 + 3 + 4 + ... + t = t(t+1)/2, or approximately 1/2 t^2.

According to given question we have

Given a velocity function v, the distance s is figured by taking the integral. In this case,

v = 20 + 5 cos(t)

s = 20t + 5 sin(t) from 0 to 25

= s(45)-s(0)

s(0) = 0

so, the distance is

s(25) = 20*25 + 5sin(25)

= 500 -0.661

=499.33 feet.

Therefore, the distance traveled in 25 seconds is 499.33 feet.

Answer:

The 5 ounce bottle is $0.98 per ounce

The 15 ounce bottle is $0.69 per ounce

The 15 ounce bottle is a better deal because the cost per ounce is lower

Step-by-step explanation:

To find the cost per ounce for each bottle, divide the cost by how many ounces are in the bottle.

4.89 ÷ 5 = 0.978

10.29 ÷ 15 = 0.686

So, the 5 ounce bottle is $0.98 per ounce, while the 15 ounce bottle is $0.69 per ounce.

The 15 ounce bottle is a better deal because the price is lower per ounce.

Buying a 15 ounces bottle for $10.29 is the better deal because it's cheaper.

Since one can buy shampoo in a 5 ounce bottle for $4.89, the cost per ounce bottle will be:

= $4.89/5

= $0.978

Since one can buy a 15 ounces bottle for $10.29, the cost per ounce bottle will be:

= $10.29/15

= $0.686

Mathematically, it will take you 315 minutes (5 hours, 15 minutes) at most to visit with all 7 clients.

We can employ mathematical operations, including addition, subtraction, division, and multiplication to determine the total time required to visit the seven clients.

Since we know that a client requires 3/4 hours or 45 minutes of your visiting time, we can multiply 45 minutes by 7.

The product of the multiplication operation gives 315 minutes, which we can convert into hours and minutes by a division operation.

The number of clients visiting today = 7

The time it a client requires of your visit time = 3/4 hours

3/4 hours = 45 minutes (0.75 x 60)

For the 7 clients, it will take you 315 minutes (45 x 7)

315 minutes equal 5 hours and 15 minutes.

Thus, using basic mathematical operations, we can conclude that, at most, you require 5 hours and 15 minutes to attend to all seven clients today.

a. 2x + 3y = 7

2y = 12x - 2

To solve this system of equations, we can begin by isolating one of the variables. Let's first isolate y in the second equation:

2y = 12x - 2

y = 6x - 1

Now we can substitute this expression for y into the first equation:

2x + 3(6x - 1) = 7

2x + 18x - 3 = 7

20x = 10

x = 1/2

Now that we know the value of x, we can substitute it back into the equation y = 6x - 1 to find the value of y:

y = 6(1/2) - 1

y = 3/2 - 1

y = -1/2

So the solution to this system of equations is (x, y) = (1/2, -1/2).

b. 2x - 9y = 12

3x + 18y = 18

To solve this system of equations, we can begin by using the first equation to solve for one of the variables. Let's solve for x:

2x - 9y = 12

2x = 9y + 12

x = (9y + 12)/2

Now we can substitute this expression for x into the second equation:

3((9y + 12)/2) + 18y = 18

(27y + 36) + 18y = 18

45y = -18

y = -4/5

Now we can substitute this value of y back into the equation x = (9y + 12)/2 to find the value of x:

x = (9(-4/5) + 12)/2

x = (3 + 12)/2

x = 15/2

So the solution to this system of equations is (x, y) = (15/2, -4/5).

There is only 1 possible 11-card hand that can be formed from a 20-card deck.

To determine the number of 11-card hands possible with a 20-card deck, we can use the concept of combinations.

The number of combinations, denoted as "nCk," represents the number of ways to choose k items from a set of n items without regard to the order. In this case, we want to find the number of 11-card hands from a 20-card deck.

The formula for combinations is:

nCk = n! / (k!(n-k)!)

Where "!" denotes the factorial of a number.

Substituting the values into the formula:

20C11 = 20! / (11!(20-11)!)

Simplifying further:

20C11 = 20! / (11! * 9!)

Now, let's calculate the factorial values:

20! = 20 * 19 * 18 * ... * 2 * 1

11! = 11 * 10 * 9 * ... * 2 * 1

9! = 9 * 8 * 7 * ... * 2 * 1

By canceling out common terms in the numerator and denominator, we get:

20C11 = (20 * 19 * 18 * ... * 12) / (11 * 10 * 9 * ... * 2 * 1)

Performing the multiplication:

20C11 = 39,916,800 / 39,916,800

Finally, the result simplifies to:

20C11 = 1

Consequently, with a 20-card deck, there is only one potential 11-card hand.

The general form of the equation of a circles is -

\((x- h)^{2}+ (y-k)^{2} = r^{2}\)

where (h, k) are the coordinates of the center of the circle and r is the radius of the circle.

Let us convert the given equation into the general form by completing the squares as follows -

\(x^{2}+ (2*4)x+ y^{2} - (2*3)y + 21 = 0\)

\(x^{2}+ (2*4)x+ 16 -16+ y^{2} - (2*3)y + 9 - 9+ 21 = 0\)

\([x^{2}+ (2*4)x+ 16] -16+ [y^{2} - (2*3)y + 9] - 9+ 21 = 0\)

4. RSTU is a trapezoid because the opposite sides RS and UT are parallel.

5. RSTU is not an isosceles trapezoid because the diagonals are not congruent.

In order to verify that RSTU is a trapezoid, we would have to determine slope of the pair of opposite sides and check whether at least one pair of opposite sides are parallel;

RU ║ ST

Slope of side RU = Slope of side ST

Slope of RU = (y₂ - y₁)/(x₂ - x₁)

Slope of RU = (1 + 3)/(5 + 3)

Slope of RU = 4/8

Slope of RU = 0.5.

Slope of RS = (y₂ - y₁)/(x₂ - x₁)

Slope of RS = (-9 + 3)/(-4 + 3)

Slope of RS = -6/-1

Slope of RS = 6.

Slope of ST = (y₂ - y₁)/(x₂ - x₁)

Slope of ST = (-2 - 1)/(10 - 5)

Slope of ST = -3/5

Slope of ST = -0.6.

Slope of UT = (y₂ - y₁)/(x₂ - x₁)

Slope of UT = (-2 + 9)/(10 + 4)

Slope of UT = 7/14

Slope of UT = 0.5.

Therefore, RSTU is a trapezoid because the opposite sides RS and UT are parallel.

Question 5.

In order to determine whether RSTU is an isosceles trapezoid, we would have to determine length of the diagonals by using the distance formula and check whether they are congruent;

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Distance RT = √[(-2 + 3)² + (10 + 3)²]

Distance RT = √170 units.

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Distance US = √[(5 + 4)² + (1 + 9)²]

Distance US = √181 units.

Therefore, RSTU is not an isosceles trapezoid because the diagonals RT and US are not congruent.
