Find the area of the circle shown. Use 3.14 as an approximation for T. Round your answer to the nearest tenth. ​

Because the sine and cosine ratios involve dividing a leg (one of the shorter two sides) by the hypotenuse (the longest side), the ratio values will never be greater than one, because (some number) / (a larger number) is always less than one.

Sine & cosine are trigonometric functions of an angle in mathematics. In the context of a right triangle, the sine and cosine of an acute angle are defined as follows: for the specified angle, the sine is the ratio of the length of the side opposite that angle to the length of the triangle's longest side (the hypotenuse), and the cosine is the ratio of the length of the adjacent leg to that of the hypotenuse.

The sine and cosine functions for an angle θ are simply denoted as sin θ and cos θ. In general, the definitions of sine and cosine can be extended to any real value expressed in terms of the lengths of specific line segments in a unit circle.

Answer: To obtain the standard form of a linear equation, we want to rearrange the equation in the form Ax + By = C. Here are the standard forms of the given equations:

5x - 6y = 12

3y - 2x - 6 = 0

7x + y - 63 = 0

14x - y + 16 = 0

To obtain the slope-intercept form of a linear equation, we want to rearrange the equation in the form y = mx + b, where m is the slope and b is the y-intercept. Here are the slope-intercept forms of the given equations:

There is no y-intercept, so this equation does not have a slope-intercept form.

y = (2/3)x + 2

y = (1/7)x + 9

y = (-7/2)x + 8

Step-by-step explanation:

The standard equation of the circle will be;

⇒ (x - 3)² + (y + 5)² = 16

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Given that;

The circle is shown in figure.

Now,

Here, By the figure;

The radius of the circle = 7 - 3

                                    = 4 units

And, The center of circle = (3, - 5)

We know that;

The standard equation of the circle is,

⇒ (x - h)² + (y - k)² = r²

Where, (h, k) = center and r is radius.

So, We get;

The standard equation of the circle is,

⇒ (x - 3)² + (y - (-5))² = 4²

Rounded to the nearest tenth, the measure of side ST is 8.0.

In order to find the measure of side ST, you will need to use the concept of similarity. If two triangles are similar, then their corresponding sides are in proportion. If we let x be the measure of side ST, then we can set up a proportion using the given information:

[tex]OP/PQ = ST/RQ[/tex]

We also know that

[tex]OP/PQ = 2/3[/tex]

and

[tex]RQ = 12[/tex]

So we can substitute these values into the proportion and solve for x:

[tex](2/3) = ST/12[/tex]

The vertical asymptotes are 2 and 3 and horizontal asymptotes is 2

An asymptote is a horizontal/vertical oblique line whose distance from the graph of a function keeps decreasing and approaches zero, but never gets there.

Vertical asymptotes can be found by solving the equation n(x) = 0 where n(x) is the denominator of the function.

Therefore, the denominator is x²-5x+6,

= x²-5x+6 = 0

using factorization method

x²-3x-2x+6 = 0

(x²-3x)(-2x+6) = 0

x(x-3) -2(x-3)

x-2 = 0 or

x-3 = 0

x = 2 or 3

The degree of the power of numerator and denominator are equal, there for the horizontal asymptote y = 2x²/x² = 2

Answer:

So the correct expansion of (4x + 1)(2x7 - 2) is 8x^27 - 8x2 + 2x7 - 2

Step-by-step explanation:

When expanding an algebraic expression like (4x + 1)(2x7 - 2), you can use the distributive property to find the product of each term in the first set of parentheses with each term in the second set of parentheses, and then add them together. The distributive property is the process of multiplying one term in the parentheses by each of the terms outside the parentheses.

Here is the correct expansion of (4x + 1)(2x7 - 2):

(4x + 1)(2x7 - 2) = 4x(2x7) + 4x(-2) + 1(2x7) + 1(-2)

= 8x^27 + -8x2 + 2x71 + -21

= 8x^27 + -8x2 + 2x7 + -2

= 8x^27 - 8x2 + 2x7 - 2

So the correct expansion of (4x + 1)(2x7 - 2) is 8x^27 - 8x2 + 2x7 - 2

It's important to note that you can also use FOIL method which is the acronym for the steps of the distributive property, First, Outside, Inside, Last.

Therefore because of this, the answer to the speed problem is that a family can travel 31.875 miles in 3/4 of an hour.

Speed is a tempo that is determined by the distance an entity travels in a predetermined period of time. Numerous methods exist for measuring speed, including miles per hour, laps per minute, and meters per second. The measurements of speed, distance, and time are related. The relationship can be expressed in three different ways:

D = RT, R = DT, & T = DR.

Here,

We are given that

Distance drives by a family=4[tex]\frac{1}{4}[/tex] miles

Time = 1/10

We have to find the rate of speed in miles per hour.

The speed formula will be used to get the velocity in miles per hour.

Distance traveled in a given amount of time equals speed.

=> Speed = 17/4 * 10

=> Speed = 42.5

So, using the calculation, we arrive at 42.5 miles per hour.

The miles traveled in 3/4 miles are therefore:

Distance is calculated as speed times time,

therefore 42.5 * 3/4 would equal 31.875 miles in distance.

Because of this, the answer to the speed problem is that a family can travel 31.875 miles in 3/4 of an hour.

The value of polynomial p(x) when x=0 is 35.

What is a polynomial?

An expression made up of indeterminates and coefficients and utilising solely the operations of addition, subtraction, multiplication, and positive-integer powers of variables is referred to as a polynomial.

The complete question is as follows:

Suppose p(x) is a polynomial of smallest possible degree such that: bullet p(x) has rational coefficients bullet p(-3) = p(\sqrt 7) = p(1-\sqrt 6) = 0 bullet p(-1) = 8 determine the value of p(0).

Given,

p(x) is a polynomial of smallest degree where

    p(-3) = p(√7) = p( 1-√6) = 0

     p(-1) = 8

 So the factors of p are (x+3),(x-√7) and (x - 1+√6)

Given p has rational coeffecients. So we should remove √7 and √6. This can be done by multiplying with conjugates.

(x-√7)*(x+√7) = x²-7

(x-1+√6) * (x-1-√6) = (x-1)² - √6² = x²-2x+1-6 = x²-2x-5  

Now the polynomial can be written as

p(x) = c (x+3)(x²-7) (x²-2x-5 )

Here c is a constant and can be determined using p(-1) = 8

p(-1) = c ( -1+3)(-1² - 7 )(-1²-2*(-1) -5)

8 = c(2)(-6)(-2)

c = 1/3

Now the polynomial p(x) = 1/3(x+3)(x²-7) (x²-2x-5 )

Therefore p(0) = 1/3 (3) (-7)(-5) = 35

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The first equation is -

5 + 0 = 0

This equation is false, as if 0 is added to any number, the result is the same number itself, and not 0.

The second equation is -

15·0 = 015·0

Any number multiplied by 0, gives the result as 0.

In the above equation LHS = RHS = 0.

Hence, this equation is true.

The third equation is -

1.4 + 2.7 = 4.1

Solving LHS -

= 1.4 + 2.7

= 4.1

So, LHS = RHS and hence, this equation is true.

The fourth equation is -

(2/3) · (5/9) = 7/12

Solving LHS -

= (2/3) × (5/9)

= 10/27

Here, LHS ≠ RHS.

Hence, this equation is false.

The fifth equation is -

4(2/3) = 5-(1/3)

Solving LHS -

4(2/3) = 14/3

Solving RHS -

= 5 - 1/3
