x = 33°

Step-by-step explanation:

From the figure attached,

FB and FC are two secants intersecting each other at point F outside the circle.

Measure of angles between the secants measures half of the difference between the intercepted arcs.

x° = [tex]\frac{1}{2}(\text{arc BC}-\text{arc DE})[/tex]

Answer:

81

Step-by-step explanation:

First we go with exponents, 2x2=4 and 5x2=25. Now we go with what's inside the parentheses so, 4 (Originally 2x2) plus 4 plus 6, which equals 14. Now we multiply 4 and 14, which equals 56. Then we add 56 and 25 which equals 81.

Answer:

+4√5

Step-by-step explanation:

Note that this is a right triangle.  Therefore, the lengths of the three sides are related through the Pythagorean Theorem:  a^2 + b^2 = c^2, where c is the length of the hypotenuse.  

Thus, x^2 + 19^2 = 21^2, or, after solving this for x^2,

x^2 = 441 - 361 = 80

x is therefore +√80, or +4√5.

Answer:

[tex]b_n = \frac{2}{27} (9^n)[/tex]

Step-by-step explanation:

Given

[tex]a_1=\frac{2}{3},\ a_n=3a_{n-1}.[/tex]

Required

An explicit rule for [tex]b_1,\ b_2,\ b_3,\ \dots[/tex]

Where [tex]b_1=a_1,\ b_2=a_3,\ b_3=a_5,\ \dots[/tex]

We have:

[tex]a_1=\frac{2}{3},\ a_n=3a_{n-1}.[/tex]

Calculate a2

[tex]a_2 = 3a_{2-1}[/tex]

[tex]a_2 = 3a_1[/tex]

[tex]a_2 = 3 * \frac{2}{3}[/tex]

[tex]a_2 = 2[/tex]

Calculate a3

[tex]a_3 = 3a_{3-1}[/tex]

[tex]a_3 = 3a_2[/tex]

[tex]a_3 = 3 *2[/tex]

[tex]a_3 = 6[/tex]

Calculate a4

[tex]a_4 = 3a_{4-1}[/tex]

[tex]a_4 = 3a_3[/tex]

[tex]a_4 = 3*6[/tex]

[tex]a_4 = 18[/tex]

Calculate a5

[tex]a_5 = 3a_{5-1}[/tex]

[tex]a_5 = 3a_4[/tex]

[tex]a_5 = 3*18[/tex]

[tex]a_5 = 54[/tex]

So:

[tex]b_1=a_1,\ b_2=a_3,\ b_3=a_5,\ \dots[/tex]

[tex]a_1=\frac{2}{3}[/tex]     [tex]a_3 = 6[/tex]     [tex]a_5 = 54[/tex]

The above sequence form a geometric sequence.

Calculate common ratio (r)

[tex]r = \frac{b_3}{b_2}[/tex]

[tex]r = \frac{a_5}{a_3}[/tex]

[tex]r = \frac{54}{6}[/tex]

[tex]r = 9[/tex]

So, the explicit formula is:

[tex]b_n = b_1 * r^{n-1[/tex]

[tex]b_1=a_1[/tex], so:

[tex]b_n = a_1 * r^{n-1[/tex]

[tex]a_1=\frac{2}{3}[/tex], so:

[tex]b_n = \frac{2}{3} * 9^{n-1[/tex]

Split:

[tex]b_n = \frac{2}{3} * \frac{9^n}{9}[/tex]

[tex]b_n = \frac{2}{3*9} (9^n)[/tex]

[tex]b_n = \frac{2}{27} (9^n)[/tex]

The explicit rule is: [tex]b_n = \frac{2}{27} (9^n)[/tex]

The result of the given equation  [tex](3x^2 - 2^x + 5) -(x^2 + 3x - 2)\\[/tex] is [tex]4x^4-10x^3 + 14x^2[/tex]

"Cubic polynomial is a type of polynomial based on the degree i.e. the highest exponent of the variable. Hence, a cubic polynomial is a polynomial with the highest power of the variable or degree is 3. A polynomial is an algebraic expression with variables and constants with exponents as whole numbers"

"The general form of a cubic polynomial is p(x): ax3 + bx2 + cx + d, a ≠ 0, where a, b, and c are coefficients and d is the constant with all of them being real numbers. An equation involving a cubic polynomial is called a cubic equation. "

The given equation is given as[tex](3x^2 - 2^x + 5) - (x^2 + 3^x - 2)[/tex]

Solving it ,we get [tex]2x^2 - 5x +7[/tex]

Now multiplying it by [tex]1/2x^2[/tex] gives us [tex]4x^4-10x^3 + 14x^2[/tex]

Hence the answer is [tex]4x^4-10x^3 + 14x^2[/tex]

The lateral surface area of the triangular prism is 480 square cm,

option (B) is correct.

It is given that the triangular prism has a 10 cm height and its sides are 16 cm, 12 cm, and 20 cm respectively.

It is required to find the lateral surface area.

It is defined as the surface area of an object excluding its top and base areas, it is different from the total area.

We know that,

The lateral surface area of triangular prism = perimeter of the      

                                                                              base×height                                                                      

                                                                        = (a + b + c ) × h

We have, a = 16, b = 20 cm, c = 12 cm, and h =10 cm.

Putting these values in the above formula, we get:

[tex]\rm = (16+20+12) \times10\\\\\rm = 48\times 10\\\\\rm = 480 \ cm^2[/tex]

Thus, the lateral surface area of the triangular prism is 480 square cm,

option (B) is correct.

The radius of the circle is around 31.65 cm. Choice B

The formula C = 2πr , where C is the circle's circumference and r is its radius, yields the circumference of a circle. In this illustration, the circle's circumference is given as 198 cm

C = 2πr

The formula to calculate the radius can be revised as follows:

r = C / (2π)

r = 198 / (2 * 3.14)

To perform the calculation, divide the numbers:

r ≈ 198 / 6.28

r ≈ 31.65

The circle's estimated radius is 31.65 centimetres as a result.

So, rounded to the closest hundredth, the estimated radius of the circle with a circumference of 198 centimetres is 31.65 centimetres.

The closest option to 31.65 in the list of possible answers is B. 31.53. It's crucial to keep in mind that choosing 3.14 as an approximation for involves some mistake and that the precise radius number might change slightly.

When rounded to the next hundredth, the radius is 31.65. This result can be compared to the other solutions to show that:

B. 31.53.

Answer:

[tex]x =\frac{-26}{3}[/tex]

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x+32−7x=−2(5x+10)

3x+32+−7x=(−2)(5x)+(−2)(10)(Distribute)

3x+32+−7x=−10x+−20

(3x+−7x)+(32)=−10x−20(Combine Like Terms)

−4x+32=−10x−20

−4x+32=−10x−20

Step 2: Add 10x to both sides.

−4x+32+10x=−10x−20+10x

6x+32=−20

Step 3: Subtract 32 from both sides.

6x+32−32=−20−32
