The surface area of the cylinder has a radius of 2 cm and a height of 5 cm is 62.8 square cm.

A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.

The surface area of the cylinder is given as

[tex]\rm Surface \ area = 2 \pi rh[/tex]

We have

r = 2 cm

h = 5 cm

Then the surface area will be

[tex]\rm Surface \ area = 2 \times 3.14\times 2\times5\\\\Surface \ area = 62.8 \ cm ^2[/tex]

Answer:

This line tells Charles that the point must lie in Quadrant 3 if r is positive or Quadrant 1 if r is negative.

The value of r is negative. Therefore, the point will lie in the opposite quadrant as the angle of rotation.

Step-by-step explanation:

With polar coordinates the first value represents the distance from the origin and the second value represents the rotation from 0. In this case the distance from the origin value is negative, which means it will be in the opposite quadrant to the angle of rotation.

(-5, −3π/4) results in the same point as (5, π/4)

A rotation of −3π/4 results in the same rotation as 5π/4

The rotation results in Quadrant 3 but because the distance value is negative the final resulting point is in Quadrant 1.

The first six terms of the sequence are -3, 3, 21, 74, 234 and 714

Step-by-step explanation:

Given the initial value a0 = -5 and the general form of the sequence given as An = 3an-1 + 12

To get the first six terms of the sequence, we will substitute for n=1 up to n= 6 in the general equation.

when n=1

A1 = 3a(1-1)+12

A1 = 3a0+12

A1 = 3(-5)+12

A1 = -15+12

A1 = -3

when n=2;

[tex]A2 = 3a(2-1)+12\\A2 = 3a1+12\\A2 = 3(-3)+12\\A2= -9+12\\A2= 3\\\\A3= 3a(3-1)+12\\A3= 3a2+12\\A3 = 3(3)+12\\A3= 9+12\\A3= 21\\\\A4= 3a(4-1)+12\\A4 = 3a3+12\\A4= 3(21)+12\\A4= 63+12\\A4 = 74\\\\A5= 3a(5-1)+12\\A5 = 3a4+12\\A5= 3(74)+12\\A5= 222+12\\A5 = 234\\\\\\A6= 3a(6-1)+12\\A6 = 3a5+12\\A6= 3(234)+12\\A6= 702+12\\A6 = 714\\[/tex]

Answer:

x = 10

Step-by-step explanation:

This is because the formula of the area of a triangle is b x h divided by 2.

Since 8 is the base, you have to find what to multiply it by to get 80 (since 80 divided by 2 is the answer, 40).

80 divided by 8 is 10, therefore the base, or x, is 10.

You can put it in the formula to double check and it will equal 40.

Answer: y^2 - 6

Step-by-step explanation:

We are given the statement which is:

The square of y decreased by the quotient of 36 and 6

We need to get the mathematical expression for the question.

Power 2 is used for square and

The sign "/" is used for quotient or division.

The sign "-" is used to subtract or decrease.

Using the sign above,

Square of y = y^2

Quotient of 36 and 6 = 36/6

The square of y decreased by the quotient of 36 and 6 = y^2 - 36/6

= y^2 - 6

Therefore, the required expression is:

y^2 - 6

The phrase is y^2 - 6.

The phrase "the square of y decreased by the quotient of 36 and 6" translates to the mathematical expression y2 - (36 / 6). This expression involves two operations:

Then, you decrease the square of y by this quotient, which gives you the final expression y2 - 6.

You have to make sure you follow this step by step

Step-by-step explanation:

Step 1:  Subtract 4x from both sides

[tex]2x^2 - 4x = 4x - 4x - 7[/tex]

[tex]2x^2 - 4x = -7[/tex]

Step 2:  Add 7 to both sides

I remember isosceles from the I sounding like eye and we have 2 eyes.

An isosceles triangle has two sides that are the same. We know the sides are the same because of the picture and if we subtract the angles 80 + 50 = 130 180-130=50 so that means that both A and C are 50 degrees so the triangle is isosceles.

My grammar isn't the best so you can make some edits but overall basically there are two sides that are the same.

Answer:

Answer: C

Step-by-step explanation:

First let’s identify that:

y = the kitten

x = the cat

Part 1 : The kitten weighs 3 pounds less than half the weight of Callie's cat.

We know that the kitten is half the size of the cat, which means the equation now looks like this:

x = [tex]\frac{1}{2}[/tex]y

But we also know that the kitten is 3 less than that equation, so now the equation is:

x = [tex]\frac{1}{2}[/tex]y -3

Part 2: Together the cat and the kitten weigh 18 pounds

Now, we have to use the other statement:

y + x = 18

But, that’s not one of the options, so we have to switch the x around and make it negative.

y = -x + 18

These are your answers!

The system of equations could be used to find the weight of each animal is option C.

Since Callie has a new kitten. The kitten weighs 3 pounds less than half the weight of Callie's cat. Together the cat and the kitten weigh 18 pounds.

Here we assume the kitten be x and cat be y

So, the equation should be

[tex]y = 1\div 2x - 3\\\\[/tex]

y = -x + 18

(24 divided by 8)x2

Answer:

x = 1

y = 1

Step-by-step explanation:

Since it gives you the value of y already, all you need to do is plug it into the equation, like so:

y = -3x + 4

1 = -3x + 4

Now, subtract 4 from both sides:

1 = -3x + 4

-4        - 4

________

-3 = -3x

Finally, divide both sides by -3:

-3 = -3x

1 = x

So now you have, x = 1 and y = 1.

x + 2x + 6 < 50

3x + 6 < 50

3x < 44

x < 14 2/3

So, you now have another set of numbers, {13, 14, 15, 16, 17}, and you know x must be smaller than 14 2/3. The only two numbers in that set that works are 13 and 14, making A: {13, 14} the correct answer.

SAMPLE ANSWER

Step-by-step explanation:

When there is an outlier in the data set, the dot plot or histogram will be skewed. In a skewed representation, the mean is pulled up or down toward the tail of the data. Therefore, skewed data affects the mean more than the median.

The median is a better measure of center than the mean in situations where the data is skewed or contains extreme outliers.

It is the middle value of the given set of numbers after arranging the given set of numbers in order.

We have,

The median and mean are both measures of central tendency used to describe the center of a data set.

The mean is the sum of all the values in a data set divided by the total number of values, while the median is the middle value when the data set is ordered from least to greatest.

The median is a better measure of center than the mean in situations where the data is skewed or contains extreme outliers.

For example, in a data set where one or a few very large or very small values are present, the mean will be influenced by these values, and will not be representative of the central tendency of the data set as a whole.

In such cases, the median is a more appropriate measure of the center as it is not influenced by outliers and better represents the "typical" value in the data set.

Thus,

When a data set is skewed or contains outliers, the median is a better measure of the center than the mean.
