The measure of BC is 24 cm.

The diagram of circle A with two tangents is given in the attached figure.

The given radius of the circle is 10 cm.

AC = 26 cm

We require to calculate the value of BC.

We have,

AD = AB = 10 cm

We know that the radius of a circle is always perpendicular to the tangent at the point of intersection. It suggests that triangle ABC is a right-angle triangle.

Using the Pythagoras theorem, we get

AB² + BC² = AC²

10² + BC² = 26²

BC² = 676 - 100

BC² = 576

Take square root on both sides,

BC = √576

BC = 24

The measure of BC is 24 cm.

Hence, the correct answer is B.

The picture below shows the graph of the  inequality of x² ≤ 4

Option C is correct.

In mathematics, an inequality is described as a relation which makes a non-equal comparison between two numbers or other mathematical expressions which is used most often to compare two numbers on the number line by their size.

A graph of inequality denotes that the variables is the set of points that represents all solutions to the inequality.

A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality.

The value of the measure of 5 is,

⇒ ∠5 = 105°

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

Two parallel lines are cut by a transversal.

And, the measure of 2 is 75°.

Here, Angle 2 and 3 are vertically opposite angle.

Hence, angle 2 and 3 are equal.

And, Angle 3 and 5 are adjacent angle.

Hence, We get;

⇒ ∠3 + ∠5 = 180°

⇒ 75 + ∠5 = 180°

⇒ ∠5 = 180 - 75

⇒ ∠5 = 105°

Thus, The value of the measure of 5 is,

⇒ ∠5 = 105°

Describe probability using an example?

A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty. The likelihood of an event occurring increases as its probability increases. The flip of a fair (impartial) coin serves as a straightforward illustration.

Total sample space = 6*6 = 36

A) Sample space for sum of 1 = 0

So probability of getting a sum of 1 = 0

B) sample space for sum of 5 = {(1,4) , (2,3), (3,2), (4,1)}

So probability of getting a sum of 5 = 4/36 = 0.11

The expression that can be used to determine the price is 1.3x

The expression to determine the price the store charges when the manufacturer charges x dollars, after marking up the price by 30%, can be calculated as follows:

Let P be the price the store charges

So, we have the following representation

P = x + (30/100)x

Divide

P = x + 0.3x

Add

P = 1.3x

So, the store charges 1.3x dollars after marking up the price by 30%.

Answer:

18 2-point shots.

Step-by-step explanation:

Two equations.

First modeling 2 point and 3 point shots as x and y.

2x + 3y = 60

Second, modeling the number of shots.

x + y = 26

Which you can alter to substitute.

x = 26 - y

Substitute.

2(26 - y) + 3y = 60

52 - 2y + 3y = 60

y = 8

Answer:

Step-by-step explanation:

The formula for the circumference of a circle is 2 * π * r, where r is the radius of the circle.

Given that the radius of the circle is 13 millimeters, the circumference of the circle is:

2 * π * 13 = 26 * π millimeters

Since the value of π is approximately 3.14, the approximate circumference of the circle is:

26 * 3.14 = 81.64 millimeters.

The solution of the inequality is:

s ≥ -0.86

And the graph can be seen on the image at the end.

Here we want to find and graph the solution set of the inequality below:

(2/5)*s + 7 ≥ 3 - 4.2*s

To do so, first we need to isolate s in one of the sides, then let's do that:

(2/5)*s + 7 ≥ 3 - 4.2*s

(2/5)*s + 4.2*s ≥ 3 - 7

(2/5 + 4.2)*s  ≥ -4

And we know that 4.2 = 21/5

Then:

(2/5 + 21/5)*s  ≥ -4

(23/5)*s ≥ -4

s ≥ -4*5/23

s ≥ -20/23

s ≥ -0.86

Luca picks his number first. then, craig picks a number from the remaining cards, these two events are Dependent.

Total number of cars are 25,

Luca picks randomly a card so probability is now 1/25 and total number of cars are now 24.

If craig have to pick then the probability of it becomes 1/24 as one card was already picked by the Luca,

So this indicated that these two events are Dependent.

In probability, dependent events are those whose occurrence influences the likelihood of occurrence of another event. Imagine there are 3 red and 6 green balls in a bag. One after the other, two balls are taken out of the bag.

Let A represent the first draw's red ball draw and B represent the second draw's green ball draw. If the first draw's ball is not put back in the bag, then A and B are dependent events because P(B) changes depending on whether the first draw's ball was red or green.

-58 is not a term of this sequence.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

The total population, h(x): of bison in the two regions 0f the park X years after 2010 is h(x) = 1050(1.14)ˣ. So the option a is correct.

The following functions represent the population of bison in two regions of a wildlife park; where X is the number of years since 2010.

f(x) = 600(1.14)ˣ

g(x) = 450(1.14)ˣ

We must tell the function that represents the total population of bison in the two park regions x years after 2010.

h(x) = Total Population

So, h(x) = f(x) + g(x)

Now put the value of f(x) and g(x)

h(x) = 600(1.14)ˣ + 450(1.14)ˣ

Take (1.14)ˣ on both side, we get

Debbie's error is that she did not include the possibility that exactly 8 passengers could fit in the van. Therefore, the correct inequality symbol to use would be less than or equal to, represented by "<=".

The correct inequality is p <= 8. This means that the number of passengers that can fit in the van is either less than or equal to 8. So, including 8 as a possible choice is also necessary to correctly represent the situation.

Answer: The interest for the loan for each day is 5000 x 6.9/100 = $345.

For the first installment, the interest will be for 60 - 1 = 59 days. So, the interest for this period will be 59 x $345/365 = $166.55.

The first installment will be $5000 + $166.55 = $5166.55.

For the second installment, the interest will be for 120 - 60 = 60 days. So, the interest for this period will be 60 x $345/365 = $168.76.

The second installment will be $5000 + $168.76 = $5168.76.

For the third installment, the interest will be for 180 - 120 = 60 days. So, the interest for this period will be 60 x $345/365 = $168.76.

The third installment will be $5000 + $168.76 = $5168.76.

Therefore, each installment will be $5166.55, $5168.76, and $5168.76.

y = -5/4x + 3

Step-by-step explanation:

slope-intercept form is:  y = mx + b

where 'm' represents slope and 'b' represents the y-intercept

basically we have to solve for 'y':

first step,  add -5x to each side to get:

-4y = 5x - 12

last step,  divide each side by -4 to get:

y = -5/4x + 3

slope equals -5/4

y-intercept equals 3
