Step-by-step explanation:

Answer:

Step-by-step explanation:

First, you have to find the perimeter of the base. You do that by adding all the sides,

There are two sides that are 13 mm and two sides that are 6 mm
13 + 13 is 26
6 + 6 is 12
26 + 12 is 38

Now you have the perimeter. Now you have to multiply is by the highest

So 38*14 (532)

Answer:

a)  13/10

b) [tex]y+15=\dfrac{13}{10}(x-5)[/tex]

c) [tex]y+2=\dfrac{13}{10}(x-15)[/tex]

d) Both equations are [tex]y=\dfrac{13}{10}x-\dfrac{43}{2}[/tex] so represent the same line

e) [tex]-\dfrac{43}{2}[/tex] °F  ⇒ y-intercept

Step-by-step explanation:

a)  Choose two ordered pairs from the table: (5, -15) and (15, -2)

Let [tex](x_1,y_1)[/tex] = (5, -15)

Let [tex](x_2,y_2)[/tex] = (15, -2)

Use the slope formula to find slope: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\implies m=\dfrac{-2+15}{15-5}=\dfrac{13}{10}[/tex]

b)  Use point-slope with (5, -15)

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

[tex]\implies y+15=\dfrac{13}{10}(x-5)[/tex]

c)  Use point-slope with (15, -2)

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

[tex]\implies y+2=\dfrac{13}{10}(x-15)[/tex]

d)

[tex]\implies y+15=\dfrac{13}{10}(x-5)[/tex]

[tex]\implies y=\dfrac{13}{10}x-\dfrac{43}{2}[/tex]

[tex]\implies y+2=\dfrac{13}{10}(x-15)[/tex]

[tex]\implies y=\dfrac{13}{10}x-\dfrac{43}{2}[/tex]

Therefore, they represent the same line

e) when x = 0:

[tex]y=\dfrac{13}{10}(0)-\dfrac{43}{2}=-\dfrac{43}{2}[/tex] °F

Represents the y-intercept on the graph

Based off of this information, it looks like there are more online shoppers than in-store shoppers, more simply because there are 4 arrays that have more online shoppers than in-store shoppers, and 3 arrays that have more in-store shoppers than online shoppers, and 1 array that has an even amount of shoppers. But if you add up the numbers for a total of 160/161, you see there are more in-store shoppers than online shoppers.

So there are more in-store shoppers total.

Answer:

Obtuse

Step-by-step explanation:

Has angle >90.

Answer:

Obtuse

Step-by-step explanation:

An acute triangle has three angles that each measure less than 90 degrees. An equilateral triangle is a triangle in which all three sides are the same length. An obtuse triangle is a triangle with one angle that is greater than 90 degrees. A right triangle is a triangle with one 90 degree angle.
Since the largest angle is 104 and is larger than 90 it is an obtuse triangle

Answer:

C

Step-by-step explanation:

Cos x has a minimum of -1.

So Let find what x value in radians will equal -1

[tex] \cos(x) = - 1[/tex]

This occurs at x=pi

[tex] \cos {}^{ - 1} (1) = \pi[/tex]

Since cos is a periodic function, we add 2pi to it continously

[tex]\pi + 2\pi n[/tex]

convert pi to 3.14

[tex]3.14 + 2(3.14)n[/tex]

[tex]3.14 + 6.28n[/tex]

Let try when n is 4

[tex]3.14+(6.28)4[/tex]

[tex]3.14 + 25.12[/tex]

[tex]28.26[/tex]

Answer:

(0, 1)

Step-by-step explanation:

The y-intercept is where a graph intersects with the y-axis. The x-coordinate would be 0, and the y-coordinate would be any real number.

Given the information above, the y-intercept is (0, 1) or 1 because its x-coordinate is 0 and y-coordinate is a real number.

Answer:

y-intercept is (0,1)

Step-by-step explanation:

When we are looking at the chart we’re looking for a point where the x is 0 and the y is 1 which is the definition of y-intercept, where the line intersects only with the y-axis

We can see this in the chart but if that point is not on there, we have another way to find it.

This is the formula, point-slope form.

(Math people are not that creative, you use it when you have the slop and a point)

First, we need to find the slope

We do this by taking two points and using the formula y2-y1 over (/) x2-x1

So our formula is y2-y1/x2-x1.

If you pick two random points, (We will use 0,1 and 1,3) and subtract them from each other, you have the slope

3 is y2 because it’s a y point and its the second point and 1 is our other point because its a y point and its the first y point

So our equation now is 3-1/x2-x1

Now we have to sub in for the x’s

Do the same thing and our equation now is…

3-1/1-0

This gets us to 2/1 which is obviously 2.

Now we have our slope so we just have to fill in for the point.

Point slope form uses the model y-y1=m(x-x1)

So we use our same two points and get

Y-1=2(x-0)

Solve this out to Slope intercept form which will give us our y-intercept.

This gets us to y=2x+1 so our y-intercept is clearly still 1!

There are 35 different groups of 4 flowers can Simon choose.

Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant. You can choose the components of combos in any order. Permutations and combinations can be mixed up.

We have,

A client asked him to select 4 of the 7 available flower options.

So, the number of combination for 4 flowers is

C(7, 4)

= 7!/ 4! (7-4)!

= 7 x 6 x 5 x 4!/ 4! x 3!

= 7 x 6 x 5/ 3x 2

= 35

Thus, there 35 different ways.

Answer:

No

Step-by-step explanation:

The 2 side lengths should be the same

Answer:

No

Step-by-step explanation:

In order for the sides to be able to create a triangle two of the given sides have to be greater than the third side once added together.

[tex]a+b > c[/tex]
[tex]1+3=4[/tex]
[tex]4=4[/tex]

Which means your answer is "no" these lengths do not create a triangle for it does not pass the Triangle Inequality Theorem.

By solving a system of equations we will see that the best pair to buy is A and C.

Here we have 3 potatoes, A, B, and C. Let's use these variables to define the weight of each potato.

Then, from the given information, we know that:

A + C = 500g

B + C = 400g

A + B = 300g

Then we have a system of equations, to solve it, first we isolate one of the variables in one of the equations. I will isolate A on the first one:

A + C = 500g

A  = 500g - C

Now we can replace that in the third equation, now we have:

B + C = 400g

500g - C + B = 300g

Now we do the same thing, this time I will isolate C.

C = 400g - B

Let's replace this on the other equation:

500g - (400g - B) + B = 300g

500g - 400g + 2*B = 300g

100g + 2*B = 300g

B = (300g - 100g)/2 = 100g

So potato B weighs 100g.

We can use that to find the weight of the other two:

C = 400g - B = 400g - 100g = 300g

A  = 500g - 300g = 200g

He wants 200g of potato, so he should buy one pair that includes potato A, which weight exactly 200g. And to get the most of his money, he should buy the pair that contains potato A and that weighs more. So the best pair will be A and C.

First convert the mixed fractions to improper fractions.

[tex](5\dfrac{2}{3})^{2}-(4\dfrac{1}{3})^{2} = (\dfrac{17}{3})^{2} - (\dfrac{13}{3})^{2}[/tex]

We can use the identity a² - b² = (a +b)(a - b)

Here a = 17/3 and b = 13/3

[tex]= (\dfrac{17}{3}+\dfrac{13}{3})(\dfrac{17}{3}-\dfrac{13}{3})[/tex]

We can add & subtract as they have common denominators.
