we have that

K is the center of circle

J -----> point of tangency

segment IK is a radius

segment JL is a chord

segment GI is a secant

segment JI is a diameter

segment GJ is a tangent

arc JIL is a major arc

arc JL is a minor arc

arc JLI is a half circle (180 degrees)

Part 2

we have that

arc ST

Remember that

arc ST+87+72=180 degrees ------> by half circle

so

arc ST=180-159

arc WV

we have

arc WV+arc UV=180 degrees -----> by half circle

arc UV=72 degrees

so

arc WV=180-72

arc VUT

arc VUT=arc VU+arc UT

substitute given values

arc VUT=72+87

The area is 25π square inches

Given a radius, r = 5 in.

The area of a circle is given by the formula:

Substituting the value of r, we have:

The area is 25π square inches

We have to use the simple interest formula

Where P = 13,000, r = 5% (0.05), t = 90 (0.25 years). Let's replace these values to find the interest

Because we have to add the total interest with the amount borrowed.

Given data:

The given figure is shown.

The area of the given figure is,

Thus, the area of the composite figure is 978 sq-inches.

As given by the question

There are given that function

Now,

To find the value of r(a^2), put x = a^2 into the function

Then,

Hence, the function is shown below:

Mean Value Theorem

Supposing that f(x) is a continuous function that satisfies the conditions below:

0. f(x) ,is continuous in [a,b]

1. f(x) ,is differentiable in (a,b)

Then there exists a number c, s.t. a < c < b and

However, there is a special case called Rolle's theorem which states that any real-valued differentiable function that attains equal values at two distinct points, meaning f(a) = f(b), then there exists at least one c within a < c < b such that f'(c) = 0.

As in our case there is no R(t) that repeats or is equal to other R(t), then there is no time in which R'(t) = 0 between 0 < t < 8 based on the information given.

Answer: No because of the Mean Value Theorem and Rolle's Theorem (that is not met).

Yesterday Ali had n Baseball cards.

Today he gave away 6 cards.

We are asked to write an expression for the number of cards Ali has left.

Ali had a total of n cards and he gave away 6 from them.

So, we have to simply subtract 6 cards from the total n cards.

Therefore, the expression is n - 6 represents the number of cards Ali has left.

ANSWER

P(gold marble) = 1/12

EXPLANATION

In total, there are:

36 marbles in the bag, where only 3 are gold marbles.

The probability is:

In this case, the number of posible outcomes is 36, because there are 36 marbles in the bag. The number of times the event can happen is 3, because there are 3 gold marbles:

The minimum number of goals scored is 0 and maximum number of goals scored is 7. The range is equal to difference between maximum number of goals and minimum number of goals.

Determine the range for the goals scored.

So answer is 7.

The function is given as,

It is asked to find the value of the expression,

This can be obtained by replacing 'x' by 7 in the given expression of the function,

Resolve the parenthesis,

Simplify the terms further,

First let's see how many hours are in a year:

We found that 1 year has 8769 hours, then if we lived 1,000,000 hours, we have to divide it by 8760 to know the number of years lived:

therefore, you would have lived 114.15 years

Answer:

150 blue marbles

Step-by-step explanation:

Hello!

If 1/2 of the marbles are yellow, and 1/8 of the marbles are red, then 3/8 of the marbles should be blue.

The percentages are as given:

To calculate the possible number of blue marbles out of the 400 marbles, we can find 37.5% of 400, as there is a 37.5% chance of getting blue for each turn.

Helen should expect to pick out 150 blue marbles.

By definition, a perfect square trinomial is a trinomial that can be written as the square of a binomial. It is in the form:

The simple trinomial is in the form:

Not all the simple trinomials can be written as the square of a binomial, then we need to check if the trinomial follows the structure of the perfect square trinomial. If it doesn't, then the factors won't be the same, and this is the main difference.

Answer:

  B.  Distributive Property

Step-by-step explanation:

You want to know the reason in the proof that best supports the transition from 5. 99-3x = 12(x+2) to 6. 99-3x = 12x+24.

You will notice that in the transition from

  5. 99-3x = 12(x+2)

to

  6. 99-3x = 12x+24

the expression 12(x+2) has been replaced by the expression 12x+24.

The property of addition and multiplication that makes it true that ...

  12(x +2) = 12x +24

is the distributive property of multiplication over addition. That property tells you that parentheses can be eliminated by multiplying each of the terms inside by the factor outside.

The total area of all four walls is 224 square meters.

According to the question,

We have the following information:

A square room has a floor area of 49 square meters.

So, we have:

Area of square = 49 square meters

Side*side = 49

Side = [tex]\sqrt{49}[/tex] m

Side of the square = 7 m

Now, the side of the floor will be the width of the wall.

So, we have the width of the wall = 7 m.

The height of the room is 8 meters.

It means that the height of the wall is 8 m.

Area of 1 rectangular wall = length*width

Area of wall = 8*7

Area of 1 wall = 56 square meters

Now, the are of 4 walls will be (4*56) square meters or 224 square meters.

Hence, the total are of all four walls is 224 square meters.

Without dividing, we can tell that 30:6 has smaller quotient between 30:5 and 30:6.

According to the question,

We have the following two expressions:

30:5 and 30:6

Now, we can easily find which expression has a smaller quotient when the dividend is the same. We need to look at the divisor. If the dividend is the same then the quotient will be smaller for the one with the greater divisor.

In this case, 30:6 has a greater divisor than 30:5 (6 is larger than 5). So, it will have smaller quotient.

Now, we can prove this by dividing both the expressions.

30/6 = 5

(So, it has smaller quotient.)

30/5 = 6

Hence, 30:6 has smaller quotient than 30:5.

Solve;

Therefore, x = -1

Answer:

Step-by-step explanation:

I would recommend looking up the magic trig hexagon, it has all of these identities and more within it.

1 - this corresponds with C as sin^2(x)+cos^2(x)=1

1-cos^2(x) - this corresponds with A, using the identity from number 1, we can rewrite it in the form sin^2(x)=1-cos^2(x)

cot(x) - for this it is important to know that cotangent is the inverse of tangent. Since tan(x)=sin(x)/cos(x), cot=cos(x)/sin(x) which is B.

sec^2(x) - much like the cos and sin pythagorean identity, sec and tan are related. sec^2(x)=tan^2(x)+1 which is answer choice E.

tan(x) - this is sin(x)/cos(x), choice D.

1) Gathering the data

E (5,1.5) Circumcenter

H (4.3,2.3) incenter

I (3.6, 2.6) is the centroid.

2) Examining the figure we can see point C and B as the vertices of the

triangle, to find the radius let's use the distance formula between point E and C

E(5, 1.5) and C(3,5)

Since the radius is a line segment from the origin to the circumference then the distance BC = radius of the circumscribed triangle

Radius = 2.28
