What is the answer to this \pi =7x-2y

Answer:

4

Step-by-step explanation:

B= 1

D= -3

Distance between the two? 4 points

1 - (-3) = 4

Answer:

-3/2

Step-by-step explanation:

Slope:

Rise: The difference between the y -coordinates of the two points is called the rise.

Run: The difference between the x-coordinates of the same two points is called the run.

First plot two points on the line.

(0, 6 )  and (4 , 0)

Rise = 6 - 0 = 6

Run = 0 - 4 = -4

[tex]\sf \boxed{Slope = \dfrac{Rise}{Run}}[/tex]

          [tex]\sf =\dfrac{6}{-4}\\\\=\dfrac{-3}{2}[/tex]

The number 102 in the sequence will be closest to 100.

A sequence in which each next term gets increased or decreased from the preceding by a constant value is called an arithmetic progression.

The difference of any two consecutive terms in an arithmetic progression is called the common difference of the AP (arithmetic progression).

Here each terms increases by 8. So, the common difference d is 8.

The first term is given to be 38.

So our sequence will be,

38, 46, 54, 62,...

nth term in an AP can be calculated by using the formula,

aₙ = a₁ + (n-1)d

To find the term nearest to 100,

100 = 32 + (n-1)8

68/8 = (n-1)

9.5 = n

But the value of n can not be a non-integer,

So the term nearest to 100 will be 9th or 10th term.

a₉ = a₁ + (9-1)d

a₉ = 8 + (8 x 8)

a₉ = 94

and,

a₁₀ = a₁ + (10-1)d

a₁₀ = 8 + (9 x 8)

a₁₀ = 102.

We can see,

a₁₀ = 102 is closest to 100.

Hence, 10th term is closest to 100.

The four ways are :

A cylinder is a 3-dimentional solid shape . It has two parallel bases which are joined by the curved surface. The cylinder has 2 circular bases one on the top and other at bottom and a curved region between them.

Important formulas of cylinder:

Base area of cylinder =  π r²

Surface area of cylinder = 2 π r( r+ h)

Volume of cylinder = π r² h

where,  h defines height and r defines the radius

According to ques ,  [tex]h= k\frac{V}{r^{2} }[/tex]

The four ways are :

1. when the value of volume V is quadrupled

  i.e. V = 4V

  then, h = [tex]k\frac{4V}{r^{2} }[/tex] = 4 ([tex]k\frac{V}{r^{2} }[/tex]) = 4h

If b^{h} < 1 then it will be a vertical stretch.

What authority possesses a power rule?

When a base is raised to a power and then the entire expression is raised to another power, the power of a power rule in exponents is used to simplify the algebraic statement.

A translation of function f is f₁ (x) = bˣ⁻h . It is equivalent to a vertical stretch or vertical compression of function f.

[tex]f_{1} (x) = b^{x - h}[/tex]

If we used the rules of powers, we know that when we have a subtraction in the power of an exponential, it can be split into a division. So the function can be rewritten as

 [tex]f_{1} (x) = \frac{b^{x} }{b^{h} }[/tex]

Remember the original function was

f(x) = bˣ

therefore

[tex]f_{1}(X) = \frac{f(x)}{b^{h} }[/tex]

this means that if [tex]b^{h} < 1[/tex] then it will be a vertical stretch.

If b^{h} < 1  then it will be a vertical stretch.

A composite function exists as a function that depends on another function. A composite function exists formed when one function exists substituted into another function.

The value of f(f(f(x))) is 1/x

In mathematics, function composition exists as an operation ∘ that takes two functions f and g, and has a function h = g ∘ f such that h(x) = g. In this operation, the function g exists used to the result of applying the function f to x.

Function composition is a mathematical procedure where two functions, f, and g, are taken and a function, h = g ∘ f, is produced such that h(x) = g(f(x)). The function g exists used in this operation on the outcome of applying the function f to x.

A function that depends on another function is referred to as a composite function. When one function is inserted into another, a composite function is produced. For instance, f(g(x)) is the composite function created when x in f is replaced with f(x). f(g(x)). You can interpret f(g(x)) as "f of g of x."

Let the given function be f(x) = 1/x

f(f(x)) = f(1/x) = 1/(1/x)

simplifying the above equation, we get

f(f(x)) = f(1/x) = x  

f(f(f(x))) = f(x) = 1/x

Therefore, the value of f(f(f(x))) = f(x) = 1/x

Step-by-step explanation:

First collect like terms:

8x2 - 2x2 + 3x + 8x - 10 + 10 (Ps: x2 and x are not the same!)

Combine them:

6x2 + 11x (the -10 and 10 cancel out)

and this is your polished answer!

The factored form of the equation x² + 6x + 8 is (x + 4) (x + 2), that is, option B.

Here, we are given a quadratic equation x² + 6x + 8

We can factorize this equation using the splitting the middle term method.

Here the coefficient of x is 6, hence, we need to spilt 6 in such a manner that the product of the split terms is 8.

6 can be written as 4 + 2 and we can see that 4 × 2 = 8

Hence, we can write the given equation as-

x² + 4x + 2x + 8

= x (x + 4) + 2 (x + 4)

= (x + 4) (x + 2)

Hence, the factored form of the equation x² + 6x + 8 comes out to be (x + 4) (x + 2), that is, option B.

The the vertices if the triangle is reflected over the y-axis and then dilated by a scale factor of 2 wii be A'(4, 6), B'(0, 0) and, C'(-2, 4).

According to the given question.

The vertices of a triangle ABC are A(-2, 3), B(0, 0), and C(1, 2).

As we know that,

The rule for reflecting a triangle over the y axis is to negate the value of x-coordinate of each point, but leave the y-value the same.

Therefore, the vertices of triangle ABC when it is reflected over y-axis are

A'(2,3)

B'(0, 0)

C'(-1, 2)

Also, when the triangle is dialated by a scale factor 2 then the vertices will be

A'(4, 6)

B'(0, 0)

The probability that the next type of stir fry ordered is shrimp is 0.28.

Given that, the frequency table provided summarizes yesterday's orders at Sizzlin' Skillets.

A frequency distribution table displays the frequency of each data set in an organized way. It helps us to find patterns in the data and also enables us to analyze the data using measures of central tendency and variance. The first step that a mathematician does with the collected data is to organize it in the form of a frequency distribution table. All the calculations and statistical tests and analyses come later.

The given frequency table is

Type of stir fry         Number of orders

Vegetable                       333

Chicken                           666

Pork                                 222

Beef                                 222

Shrimp                             555

As we know, probability of an event = Number of favourable outcomes / Total number of outcomes

Here, the number of favourable outcomes = 555

The total number of outcomes = 333+666+222+222+555 = 1998

So, the probability of getting shrimp = 555/1998

Step-by-step explanation:

To find the required polynomial, multiply 2x² and the quotient.

Multiply each term of (7x⁶ - 6x⁴ + 8x²) by 2x².

2x² * 7x⁶ = (2*7) *x²⁺⁶ = 14x⁸

Required polynomial =2x² *(7x⁶ - 6x⁴ + 8x²)

                                   = (2x²*7x⁶) - (2x²*6x⁴) + (2x²*8x²)

                                    = 14x⁸ - 12x⁶ + 16x⁴

Step-by-step explanation:

what form should the equation have ?

I assume slope-intercept

y = ax + b

"a" being the slope, "b" being the y-intercept (the y value when x = 0).

but since we have the slope and a point, we can start with the point-slope form and transform it :

y - y1 = a(x - x1)

"a" is again the slope, (x1, y1) is the point.

so,

y - 7 = -5/3 × (x - -3) = -5/3 × (x + 3) = -5x/3 - 5

and therefore

y = -5x/3 + 2
