Question is in the picture (I got it wrong)

As tangents from a single point to the circle are equal in measure

ABC is isosceles

<A=60°

We know the radius hits any tangent on right angles

So

Now

accurate value

Answer:

[tex]x=4\sqrt{3}[/tex]

Step-by-step explanation:

If two tangents to a circle meet at one exterior point, the tangent segments are congruent.   Therefore, AC = BC

This means that ΔABC is an isosceles triangle and so
∠ABC = ∠BAC = 60°

The tangent of a circle is always perpendicular to the radius.

Therefore, ∠PAC = 90°

With this information, we can calculate ∠PAD:

⇒ ∠PAD + ∠BAC = ∠PAC

⇒ ∠PAD + 60° = 90°

⇒ ∠PAD = 90° - 60°

⇒ ∠PAD = 30°

We now have a side length and an angle of ΔPAD (shown in orange on the attached diagram).  So using the cos trig ratio, we can calculate [tex]x[/tex]:

[tex]\sf \cos(\theta)=\dfrac{A}{H}[/tex]

where:

Given:

[tex]\implies \cos(30^{\circ})=\dfrac{6}{x}[/tex]

[tex]\implies x=\dfrac{6}{\cos(30^{\circ})}[/tex]

[tex]\implies x=\dfrac{6}{\frac{\sqrt{3}}{2}}[/tex]

[tex]\implies x=4\sqrt{3}[/tex]

2) multiply the two terms together - add exponents

The area covered by the napkin is 56 square centimeters

This is calculated using:

[tex]Area = \frac 12 ab\sin(C)[/tex]

Where:

a = 15, b = 5 and C = 30

So, we have:

[tex]Area = \frac 12 * 15 * 15 * \sin(30)[/tex]

Evaluate the product

Area = 56.25

Approximate

Area = 56

Hence, the area covered by the napkin is 56 square centimeters

Answer:

n = 7.

Step-by-step explanation:

Sum S of an AP = (n/2)[2a + d(n - 1)]

112 = (n/2)[2*25 - 3(n -1)]

n/2 (53 - 3n) = 112

n(53 - 3n) = 224

-3n^2 + 53n - 224 = 0

3n^2 - 53n + 224 = 0

(3n - 32 )(n  - 7 ) = 0

n = 7, 32/3

So n must be 7 as its a whole number.

A function assigns the values. The average rate of change for the given function g(x) is 1.

A function assigns the value of each element of one set to the other specific element of another set.

The average rate of change of a function is given by the formula,

Average rate of change, = [f(b)-f(a)]/(b-a), [a,b]

Where a is the lower limit and b is the upper limit.

Given the upper limit for the function is 0, therefore, the value of a is 0, similarly, the value of b is -9. Thus,

a = 0

g(a) = 0²+10(0)+20 = 20

b = -9

g(b) = (-9)²+10(-9)+20 = 11

The average rate of change for the function g(x), can be written as,

[tex]\text{Average rate of change}= \dfrac{g(-9)-g(0)}{-9-0}=\dfrac{11-20}{-9} = 1[/tex]

Hence, the average rate of change for the given function g(x) is 1.

Factorising the polynomial 5x³ + 35x² + 6x + 42, the value of A is 6.

Factorising a polynomial simply means to decompose the polynomial into a product of two or more polynomials.

Therefore, let's factorise 5x³ + 35x² + 6x + 42 and find the value of A

(5x² + A)(x + B)

Therefore,

5x³ + 35x² + 6x + 42

5x³ + 6x  + 35x² + 42

x(5x² + 6) + 7(5x² + 6)

Therefore,

The general formula for a tangent and secant is

tangent^2 = external segment * full length of the secant.

Givens

tangent length = x

external segment = 7

secant length = 7+ 21

Formula

x^2 = 7 * (7 + 21)                         Remove brackets

x^2 = 7 * 28                                Combine

We will see that the vertex of the quadratic equation is at (1, 14)

For a general quadratic:

[tex]y = a*x^2 + b*x + c[/tex]

The x-component of the vertex is at:

[tex]x = -b/2a[/tex]

In this case, we have:

[tex]y = -2x^2 + 4x + 12[/tex]

Then the vertex is at:

[tex]x = -4/(2*-2) = 1[/tex]

To get the y-component of the vertex, we need to evaluate in x = 1.

[tex]y = -2*1^2 + 4*1 + 12 = -2 + 4 + 12 = 14[/tex]

Then we conclude that the vertex is at (1, 14), so the correct option is d.

The 90 gallons of water is in the fish tank if the fish tank has 240 quarts of water. Levi adds another 120 quarts to the tank.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, multiplication by a conversion factor.

We have a fish tank has 240 quarts of water.

Levi adds another, 1201 quarts to the tank.

Total water in the tank = 240 + 120 = 360 quartz

To convert quartz to gallon, divide by 4

Total water in the tank = 360/4 = 90 gallons

Thus, the 90 gallons of water is in the fish tank if the fish tank has 240 quarts of water. Levi adds another 120 quarts to the tank.

Answer:

The side b is 2√6 unit

Step-by-step explanation:

in right triangle ΔABC,∠C=900,a=5,c=7;c is

the side opposite to the right angle, so it is hypotenuse,

aandb are the adjacent sides of the right angle .

We know in right triangle ΔABC,a²+b²=c²

∴5²+b²=7²or

b²=49−25=24

∴√b²=√24

b=√24

b=2√6

. The side b is 2√6 unit [Ans]

AB = 7 cm

CB = 5 cm

AC = 2√6cm

According to Pythagoras Theorem,

AC²=BC²+AB²

(2√6)²=5²+7²

24=25+49

24=74

Hence, it is not a right-angled triangle ABC.

Answer:

g(p + 4) = [p² + 8p + 21 / 3p + 12]

Step-by-step explanation:

Function :

g(x) = (x² + 5) / 3x

Substitute x = p + 4 :

⇒ g(p + 4) = [(p + 4)² + 5] / 3(p + 4)

⇒ g(p + 4) = [p² + 8p + 16 + 5 / 3p + 12]

⇒ g(p + 4) = [p² + 8p + 21 / 3p + 12]

Considering the given probabilities, it is found that the correct option about whether the events are independent is given as follows:

p(x) · p(y) = p(x and y). They are independent because p(x) p(y) = p(x and y).

Two events, A and B are independent, if:

[tex]P(A \cap B) = P(A)P(B)[/tex]

Researching this problem on the internet, the probabilities are given as follows:

[tex]P(X) = \frac{4}{5}, P(Y) = \frac{1}{4}, P(X \cap Y) = \frac{1}{5}[/tex]

Hence:

[tex]P(X)P(Y) = \frac{4}{5} \times \frac{1}{4} = \frac{1}{5} = P(X \cap Y)[/tex]

Hence the events are independent and the correct option is given by:

p(x) · p(y) = p(x and y). They are independent because p(x) p(y) = p(x and y).

Let's use examination results to butress our point. A good average examination results mean that the students have a good understanding of what was covered in the subject.

Let's say the average pass mark for a subject is 50. In this situation, someone who scores 50 and above is believed to understand the subject and has a pass mark.

         ➪ First, the word "quotient" indicates that we divide.

➪ The word "difference" indicates that we subtract.

        ✳︎ Here, we are asked to subtract  a number minus 8.

Let the number be x.

Since the difference of x and 8 means we subtract x minus 8, this expression looks as follows:-

  ◈     Now, we are also asked to find the quotient of 7 and the difference of a number and 8, which equals [tex]\bold{x-8}[/tex].
