Can someone please explain to me how to find y=Mx+b? We’ve learned this a long time ago and I kinda forgot .. can’t find a solution anywhere else :/

Answer:

Area = 62.8 cm²

Step-by-step explanation:

In the figure attached a triangle has been given with two sides and included angle between them.

Measures of two sides are 10 cm and 13 cm.

Measure of included angle = 105°

Since area of a triangle with two sides (a and b) and included angle (θ) is,

[tex]\text{Area}=\frac{a.b.\text{sin}\theta}{2}[/tex]

        = [tex]\frac{10\times13\times \text{sin(105)}}{2}[/tex]

       = 62.79

       ≈ 62.8 cm²

Therefore area of the given triangle is 62.8 cm²

Answer:

length of rectangle = 5

width of rectangle = 5

Area of rectangle = 25

Step-by-step explanation:

Since the length of the rectangle is "x", and the value of the area is given by the product of the length "x" times the width "10-x", indeed, the area "y" of the rectangle is given by the equation:

[tex]y=x\,(10-x)=10x-x^2[/tex]

Now, they tell us that the area of the rectangle is such that coincides with the maximum (vertex) of the parabola this quadratic expression represents. So in order to find the dimensions of the rectangle and therefore its area, we find the x-coordinate for the vertex, and from it, the y-coordinate of the vertex, which is the rectangle's actual area.

Recall that the formula for the x of the vertex of a quadratic of the form :

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

is given by the formula:

[tex]x_{vertex}=-\frac{b}{2\,a}[/tex]

which in our case gives:

[tex]x_{vertex}=-\frac{b}{2\,a}\\x_{vertex}=-\frac{10}{2\,(-1)}\\x_{vertex}=5[/tex]

Therefore, the length of the rectangle is 5, and its width (10-x) is also 5.

The area of the rectangle is therefore the product of these two values: 5 * 5 = 25

Which should coincide with the value we obtain when we replace x by 5 in the area formula:

[tex]y=10x-x^2\\y=50-(5)^2\\y=50-25\\y=25[/tex]

Answer:

True, r represents the distance from a point to the pole when plotting that point in polar coordinates.

Step-by-step explanation:

Given: The statement '' The value of r represents the distance from a point to the pole when plotting that point in polar coordinates ''

To state: whether the given statement is true or false

Solution:

In the cartesian coordinate system, any point is represented by the coordinates  [tex](x,y)[/tex]

In polar-coordinates system, distance of the point from the origin (pole)(r) and the angle [tex](\theta)[/tex] that the line joining the point to the origin makes with the positive  x -axis are used as polar coordinates. Polar coordinates are of form [tex](r,\theta)[/tex]

True, r represents the distance from a point to the pole when plotting that point in polar coordinates.

true

Answer:

5.225 miles on thursday or 209/40

Step-by-step explanation:

if we make it into decimals he runs 16.25 miles every week. on sunday he runs 6.375 miles and on tuesday it is 4.4. we are going to add what he’s run so far so

6.375 + 4.4 = 10.775 and then we will subtract that from 16.25 to get 5.225 left for thursday

Answer:

English,French,Vietnamese,Chinese,Ukrainian,other

Step-by-step explanation:

so basically the question is asking for us to convert the fractions into decimals and then, order the them from greatest to least

Q:how do you convert a fraction into a decimal?

A: numerator divided by denominator for example if you had to convert 7/9 into a decimal you would do 7 divided by 9!!!

English:1/4 is equivalent to 0.25

Ukrainian:1/20 is equivalent to 0.05

Vietnamese:0.02 is already in decimal form

French:1/10 is equivalent to 0.1

Chinese:0.02 is already in decimal form

Other:0.06 is already in decimal form

Now we got all the fractions converted into decimals

0.25,0.05,0.02,0.1,0.02,0.06

Now we have to put these number from greatest to least

Q:how do we put it in greatest to least?

A: if there are more zeros in the place value its more likely to be a small number for example 0.06 is smaller than 0.3

0.25 is the greatest

0.1 is the second greatest

0.02 is the third greatest

0.02 is the third greatest

0.05 is the 4th greatest

0.06 is the 5th greatest

Now we got them from greatest to least so we match the decimal numbers to the language

Starting from greatest to least is: English,French,Vietnamese,Chinese,Ukrainian,other

Answer:

Yuron's painting is 36 inches wide.

Step-by-step explanation:

Given that Yuron is sketching a scale drawing of a famous painting which is 54 inches wide and 72 inches long. He used a scale factor of [tex]\frac{2}{3}[/tex] to make his sketch.

We are given to find the width of Yuron’s sketch.

Let, w and w' represents the width of the famous painting and  Yuron's painting.

Then, w = 54 inches,  w' = ?

We know that the scale factor is defined by

[tex]S=\frac{Length of a side of a dilated figure}{Length of the corresponding side of the original figure}[/tex]

Therefore, we have

[tex]\frac{2}{3} =\frac{Width og Yuron's painting}{Width of the famous painting}[/tex]

[tex]\frac{2}{3} = \frac{w}{w}[/tex]

[tex]\frac{2}{3}=\frac{w}{54}[/tex]

[tex]\frac{2}{3}=\frac{2*54}{3}[/tex]

[tex]w= 36[/tex]

Thus,  Yuron's painting is 36 inches wide.

Answer:

Yuron's painting is 36 inches wide.

Answer:

The step to take to avoid fraction is to solve for y in equation 2

Step-by-step explanation:

Given

-9x+ 4y =- 10

-9x+ 3y = 3

Required:

Step for solving using substitution (avoiding fraction)

Let -9x+ 4y =- 10  represent equation 1

and -9x+ 3y = 3 represent equation 2

The following points are to be noted

Having said that, the step to take to avoid fraction is to solve for y in equation 2

Check

[tex]-9x+ 3y = 3[/tex]

Add 9x to both sides

[tex]9x-9x+ 3y = 3 + 9x[/tex]

[tex]3y = 3 + 9x[/tex]

Divide through by 3

[tex]\frac{3y}{3} = \frac{3 + 9x}{3}[/tex]

[tex]y = \frac{3 + 9x}{3}[/tex]

Split fraction

[tex]y = \frac{3}{3} + \frac{9x}{3}[/tex]

[tex]y = 1 + 3x[/tex]

At the point, the expression of y can then be substituted in equation 1

Answer: solve for y in the second equation

Answer:

It is the odd number 1009

Step-by-step explanation:

Notice that this problem involves the addition of a number "1" per consecutive pair (a number minus the integer that immediately precedes it), so it adds "1" (one) every couple of consecutive numbers.

2018 - 2017 = 1

2016 - 2015 = 1

...

4- 3 = 1

2 - 1 = 1

That means it is the addition of 2018/2 = 1009 numbers "1". This clearly results on the number 1009, which is an odd number.

Answer:

Option D [[tex]y=6.61\,*\,1.55^x[/tex]] in the list of possible answers

Step-by-step explanation:

For this problem you are supposed to use a calculator that allows you to do an exponential regression. There are many tools that can help you with that, depending on what your instructors has assigned for your class.

I am showing you the results of a graphing tool I use, and which after entering the x-values and the y-values in independent "List" forms, when I request the exponential regression to fit the data, I get what you can see in the attached image.

Notice that the exponential of best fit with my calculator comes in the form:

[tex]y=A\,e^{k\, x}[/tex]

with optimized parameters:

[tex]A \approx 6.6114\,\,\,and\,\,\, k=0.4378321[/tex]

Notice as well that since:

[tex]e^{0.4378321} \approx 1.5490[/tex]

the exponential best fit can also be written:

[tex]y=6.611403\,\,*\,e^{0.4378321\, x}=6.611403\,*\,1.549^{\,x}[/tex]

and this expression is very close to the last option shown in your list of possible answers

Answer:   [tex]\bold{y=7cos\bigg(\dfrac{2\pi}{7}x\bigg)}[/tex]

Step-by-step explanation:

y = A cos (Bx - C) + D

The minimum is -7 and the max is 7 so A = 7 and D = 0

Period is 7.  Since P = 2π/B then 7 = 2π/B --> B = 2π/7

Nothing was stated about a phase shift so you can use any value for C. I chose C = 0.

Now, input A = 7, B = 2π/7, C = 0, & D = 0 into the equation

[tex]y=7\cos\bigg(\dfrac{2\pi}{7}x-0\bigg)+0\\\\\\\text{Simplify}:\\y=7\cos\bigg(\dfrac{2\pi}{7}x\bigg)[/tex]
