Answer:

[tex] y=0.46591x+7.71591[/tex]

Step-by-step explanation:

Labelled points are [tex] (21,\: 17.5)=(x_1,\:y_1) \: \&\:(43,\: 27.75)=(x_2,\:y_2) [/tex]

Slope of line (m) [tex] =\frac{27.75-17.5}{43-21} =\frac{10.25}{22} =\frac{41}{88} [/tex]

Equation of line in point - slope form is given as:

[tex] y-y_1 = m(x-x_1) [/tex]

[tex] \therefore y-17.5= \frac{41}{88} (x-21) [/tex]

[tex] \therefore y= \frac{41}{88} x-\frac{861}{88}+17.5[/tex]

[tex] \therefore y= \frac{41}{88} x+17.5-\frac{861}{88}[/tex]

[tex] \therefore y= \frac{41}{88} x+\frac{1,540-861}{88}[/tex]

[tex] \therefore y= \frac{41}{88} x+\frac{679}{88}[/tex]

[tex] \therefore y=0.465909091x+7.71590909[/tex]

[tex] \therefore y=0.46591x+7.71591[/tex]

Answer:

[tex]V=7.45\times 10^{15}\ mm^3[/tex]

Step-by-step explanation:

The radius of each lollipop is 121212 mm

We need to find the volume of each lollipop. The volume of a sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Put all the values,

[tex]V=\dfrac{4}{3}\times 3.14\times (121212 )^3\\\\V=7.45\times 10^{15}\ mm^3[/tex]

So, the volume of each lollipop is equal to [tex]7.45\times 10^{15}\ mm^3[/tex].

The answer to the question is C

Answer:

16 yd

Step-by-step explanation:

If a is missing, then use the square root of c^2-b^2. In this case that means you find the square root of 20^2-12^2. 20^2 is 400, and 12^2 is 144. When you subtract 144 from 400 you get 256. The square root of 256 is 16. I hope this helps :)

Answer:

Answer:

Yes, the given triangle is right angled

Step-by-step explanation:

To confirm if the given triangle is right angled, we have to apply pythagoras theorem. It states, if a triangle is right angled then

Hypotenuse² = Base² + Perpendicular²

We know that the longest side is hypotenuse.

ie; (145)² = (143)² + (24)²

(145)² = 20449 + 576

21025 = 21025

As LHS = RHS, it is clear that the given triangle with sides 24, 143 and 145 units is right angled

Answer:

(8, -1)

Step-by-step explanation:

The midpoint given two points (x1, y1) and (x2, y2) is:

([x1 + x2] / 2, [y1 + y2] / 2)

We have the point (x1, y1) as (-8, -7) and the midpoint as (0, -4). We can plug them in and create two equations, one to find x2, and another for y2.

0= [-8 + x2] / 2

0 = -8 + x2

x2 = 8

-4 = [-7 + y2] / 2

-8 = -7 + y2

y2 = -1

Therefore, point B is (8, -1)

Option D is the correct answer

Answer:

A

Step-by-step explanation:

The product of  the expression [tex]\frac{x^2 - 16}{2x + 8} * \frac{x^3 - 2x^2 + x}{x^2 + 3x - 4}[/tex]  is [tex]\frac{x(x- 1)(x - 4)}{x(x + 4)}[/tex]

An expression is an algebraic term used for a mathematical statement that include variables and mathematical operations

Below is how to calculate the product

The product expression is given as:

[tex]\frac{x^2 - 16}{2x + 8} * \frac{x^3 - 2x^2 + x}{x^2 + 3x - 4}[/tex]

Express x^2 - 16 as a difference of two squares

[tex]\frac{(x - 4)(x + 4)}{2x + 8} * \frac{x^3 - 2x^2 + x}{x^2 + 3x - 4}[/tex]

Divide the expression

[tex]\frac{x - 4}{2} * \frac{x^3 - 2x^2 + x}{x^2 + 3x - 4}[/tex]

Factorize the other fraction

[tex]\frac{x - 4}{2} * \frac{x(x^2 - 2x + 1)}{(x -1)(x + 4)}[/tex]

Further factorize

[tex]\frac{x - 4}{2} * \frac{x(x- 1)(x - 1)}{(x -1)(x + 4)}[/tex]

Divide

[tex]\frac{x - 4}{2} * \frac{x(x- 1)}{x + 4}[/tex]

Multiply the fractions

[tex]\frac{x(x- 1)(x - 4)}{x(x + 4)}[/tex]

Hence, the product of  [tex]\frac{x^2 - 16}{2x + 8} * \frac{x^3 - 2x^2 + x}{x^2 + 3x - 4}[/tex]  is [tex]\frac{x(x- 1)(x - 4)}{x(x + 4)}[/tex]

Answer:

50.24 cm²

Step-by-step explanation:

a = πr^2

r = d/2 = 8/2 = 4

a = 3.14(4²)

a = 3.14 * 16

a = 50.24 cm²

Equation,

[tex]y - y1 = m(x - x1)[/tex]

Plugging in our values,

[tex]x1 = - 2, \: y1 = 4, \: m = 3[/tex]

[tex]y - 4 = 3(x - ( - 2))[/tex]

[tex]y - 4 = 3(x + 2)[/tex]

So the equation is,

[tex]y - 4 = 3(x + 2)[/tex]

Answer:

[tex]x = 3[/tex]

Step-by-step explanation:

Given

[tex]y = -2x^2 + 12x +7[/tex]

Required

The x coordinate of the vertex

Using the general form:

[tex]y = ax^2 +bx +c[/tex]

The x coordinate is:

[tex]x = -\frac{b}{2a}[/tex]

In [tex]y = -2x^2 + 12x +7[/tex]

[tex]a = -2[/tex]

[tex]b = 12[/tex]

[tex]c = 7[/tex]

So, we have:

[tex]x = -\frac{b}{2a}[/tex]

[tex]x = -\frac{12}{2*-2}[/tex]

[tex]x = -\frac{12}{-4}[/tex]

[tex]x = \frac{12}{4}[/tex]

[tex]x = 3[/tex]

Answer:8

Step-by-step explanation:

If I remember correctly, if the numbers are inside the lines like these || that means absolute value. So the negative sign would cancel out and the one on the outside would carry over, making it a -8. The opposite of  -8 is 8.

Answer:

x = -8 Hope that helps bye!

Step-by-step explanation:

1. Subtract 3x from both side -5=5x+11-3x

2. Simplify 5x+11-3x= 2x+11

3. Subtract 11 from both sides -5-11=2x

4. Simplify -5-11= -16=2x

5. Divide both sides by 2 -16/2=x

4. Simplify 16/2 = -8 = x

5. Switch sides x= -8 would be your answer and if you want to check it just do 3x-5=5x+11 let x=-8  1. 3×-8-5=5×-8+11

2. 3×-8= -24 do -24-5=5×-8+11

3. Simplify 5×-8= -40 do -24-5=-40+11

4. Simplify -24-5= -29 do -29= -40+11=-29

-29=-29 this shows that x= -8 is your answer if you want to see if I'm right.

Answer:

[tex]Vertex = (\frac{1}{2},\frac{7}{4})[/tex]

Step-by-step explanation:

Given

[tex]f(x) = x^2 - x +2[/tex]

Required

The vertex

We have:

[tex]f(x) = x^2 - x +2[/tex]

First, we express the equation as:

[tex]f(x) = a(x - h)^2 +k[/tex]

Where

[tex]Vertex = (h,k)[/tex]

So, we have:

[tex]f(x) = x^2 - x +2[/tex]

--------------------------------------------

Take the coefficient of x: -1

Divide by 2: (-1/2)

Square: (-1/2)^2

Add and subtract this to the equation

--------------------------------------------

[tex]f(x) = x^2 - x +2[/tex]

[tex]f(x) = x^2 - x + (-\frac{1}{2})^2+2 -(-\frac{1}{2})^2[/tex]

[tex]f(x) = x^2 - x + \frac{1}{4}+2 -\frac{1}{4}[/tex]

Expand

[tex]f(x) = x^2 - \frac{1}{2}x- \frac{1}{2}x + \frac{1}{4}+2 -\frac{1}{4}[/tex]

Factorize

[tex]f(x) = x(x - \frac{1}{2})- \frac{1}{2}(x - \frac{1}{2})+2 -\frac{1}{4}[/tex]

Factor out x - 1/2

[tex]f(x) = (x - \frac{1}{2})(x - \frac{1}{2})+2 -\frac{1}{4}[/tex]

[tex]f(x) = (x - \frac{1}{2})^2+2 -\frac{1}{4}[/tex]

[tex]f(x) = (x - \frac{1}{2})^2+ \frac{8 -1 }{4}[/tex]

[tex]f(x) = (x - \frac{1}{2})^2+ \frac{7}{4}[/tex]

Compare to: [tex]f(x) = a(x - h)^2 +k[/tex]

[tex]h = \frac{1}{2}[/tex]

[tex]k = \frac{7}{4}[/tex]

Hence:

[tex]Vertex = (\frac{1}{2},\frac{7}{4})[/tex]

Answer:

[tex]P(x > 4.5)= 0.983943[/tex]

Step-by-step explanation:

Given

[tex]\mu = 6[/tex]

[tex]\sigma = 0.7[/tex]

Required

[tex]P(x > 4.5)[/tex]

Start by calculating the z score

[tex]z = \frac{x - \mu}{\sigma}[/tex]

So:

[tex]z = \frac{4.5 - 6}{0.7}[/tex]

[tex]z = \frac{-1.5}{0.7}[/tex]

[tex]z = -2.143[/tex]

So, we have:

[tex]P(x > 4.5)= 1 - P(x < 4.5)[/tex]

This gives:

[tex]P(x > 4.5)= 1 - P(x < z)[/tex]

[tex]P(x > 4.5)= 1 - P(x < -2.143)[/tex]

Using the z score probability table, we have:

[tex]P(x > 4.5)= 1 - 0.016057[/tex]

[tex]P(x > 4.5)= 0.983943[/tex]
