Answer:

y=4x+13  or y-5=4(x+2)

Step-by-step explanation:

we know that

The equation of the line into point slope form is equal to

y-y1=m(x-x1)

In this problem we have

m=4

(x1,y1)=(-2,5)

substitute

y-5=4(x+2) ----> equation of the line into point slope form

Convert to slope intercept form

y-5=4x+8

y=4x+8+5

y=4x+13 ----> equation of the line into slope intercept form

Answer:

The statement which not true is (A)

Step-by-step explanation:

* At first lets revise the volume of the cone and the cylinder

- The cone has circular base and one vertex

- Its height is the line joining the vertex and the center of the base

- Its volume is 1/3(BH), where B is the area of its base and H is its height

- The cylinder has two circular bases

- Its height the line joining between the centers of the two bases

- Its volume = BH, where B is the area of its base and H is its height

* Now lets solve the problem

- The ice cream cup is shaped cylinder with diameter 3 inches

  and height 3 inches

- The ice ream cone is shaped a cone with diameter 4 inches

  and height 6 inches

* Lets find the volume of the ice cream cup

- The volume of the ice cream cup = BH

∵ B = πr² ⇒ area the circle

∵ Its diameter is 3 inches

∵ The radius = 1/2 the diameter

∴ r = 3 × 1/2 = 1.5 inches

∴ B = π(1.5)² = 2.25π inches²

∵ H = 3 inches

∴ V = 2.25 × 3 = 6.75π inches³

* Lets find the volume of the ice cream cone

- The volume of the ice cream cone =1/3 BH

∵ B = πr² ⇒ area the circle

∵ Its diameter is 4 inches

∵ The radius = 1/2 the diameter

∴ r = 4 × 1/2 = 2 inches

∴ B = π(2)² = 4π inches²

∵ H = 6 inches

∴ V = 1/3 × 4π × 6 = 8π inches³

* Lets find the right answer

# (A)

∵ The volume of 24-pack of ice ream cups = 24 × 6.75π = 162π inches³

∵ The volume of 21-pack of ice ream cones = 21 × 8π = 168π inches³

∵ 162π < 168π

∴ (A) Not true

# (B)

∵ The volume of 12-pack of ice ream cups = 12 × 6.75π = 254.5 inches³

∵ 254.5 inches³ > 250 inches³

∴ (B) is true

# (C)

∵ The volume of 14-pack of ice ream cons = 14 × 8π = 351.9 inches³

∵ 351.9 inches³ > 350 inches³

∴ (C) is true

# (D)

∵ The volume of 12-pack of ice ream cups = 12 × 6.75π = 81π inches³

∵ The cylinder container has height = 8 inches

∵ The cylinder container had diameter = 6 inches

∴ its raduis = 1/2 × 6 = 3

∵ The volume of the cylinder container = BH

∵ B = πr² = π(3)² = 9π

∴ Its volume = 9π × 8 = 72π

∵ 81π > 72π

∴ (D) is true

* The statement which not true is (A)

Answer:

No diagram and no explanation what 9 is.

However, if it is an octagon with each side equal to 9 then

area = (# of sides * side^2) / (4 * tan (180 # of sides))

area = 8 * 9 * 9 / (4* tan (180 / 8)

area = 648 / 4 * 0.41421

area = 391.1059607446

answer is C

Step-by-step explanation:

The area of the considered octagon which has distance from its center to the vertex of 9 m is given by: Option b). 229.1 m²

If the regular octagon has sides of 'a' units, then its area is:

[tex]A = 2(1+\sqrt{2})a^2 \: \rm unit^2[/tex]

Consider the attached figure below (second figure too).

If we find the value of 'a', then we can use the above formula.

Since there are 8 equal sides in a regular octagon, the angle from center to each of the side is full angle / 8 = 360/8 = 45 degrees.

Since the angle OA is perpendicular on BC, due to symmetry, we have the angle BOC divided into 2 parts.

Thus, we get:

m∠AOB = 45/2 degrees = 22.5°

Using the sine ratio from the perspective of angle AOB, we get:

[tex]\sin(m\angle AOB) = \dfrac{|AB|}{|OB|}\\\\\sin(22.5^\circ) = \dfrac{a/2}{9}\\\\a \approx 2 \times 9 \times 0.38268 \approx 6.888[/tex] meters

(since length of AB is half of length of BC, which is 'a' units).

Thus, we get:

[tex]A = 2(1+\sqrt{2})a^2 \approx 2(1+\sqrt{2})(6.888)^2 \approx 229.1\: \rm m^2[/tex]

Thus, the area of the considered octagon which has distance from its center to the vertex of 9 m is given by: Option b). 229.1 m²

6. random

Step-by-step explanation:

Answer:

1) Uni-modal 2) Bi-modal 3) Skewed right 4) Skewed left 5) Uniform 6) Random  

Step-by-step explanation:

We are given the following information in the question:

1) Since we can see in the graph, there is one observation with highest frequency. Thus, this graph represents a uni-modal data

2) It s clearly seen that there are two values with highest frequencies. These two observations can be treated as the mode of the data. Thus, there are two modes. Thus, the graph represents a bi-modal data.

3) We can see that most of the data lies on the left side of data and very less data is there on the left tail. Hence, the graph is positively skewed or skewed on the right.

4) We can see that most of the data lies on the right side of data and very less data is there on the right tail. Hence, the graph is negatively skewed or skewed on the left.

5. Since all the observations are very close to each other almost equal we could say that the data have a uniform distribution.

6. The above data set have a random distribution since no pattern are observed.

Answer:

3.71 miles farther.

Step-by-step explanation:

To answer this, subtract 3  5/8 miles from 7  1/3 miles:

22/3 - 29/8 (miles)

Here the LCD is 24.  Thus, we have:

176      87                       89

------ - ------  (miles), or -------  (miles)

24       24                       24

Arun has to walk another 89/24 miles, or 3.71 miles.

Check:  do 3  5/8 miles and 3.71 miles add up to 7  1/3 miles?  Yes, approximately.

Arun has 89/24 miles left to walk to reach his friend's house.

Arun decided to walk 7 1/3 miles to his friend's house. After walking 3 5/8 miles, he stopped to rest. To calculate how much farther Arun has to walk to reach his friend's house, we subtract the distance he has already walked from the total distance he needs to walk.

The total distance to his friend's house: 7 1/3 miles = 7 + 1/3 = (7 × 3 + 1)/3 = 22/3 miles.

Distance already walked: 3 5/8 miles = 3 + 5/8 = (3 × 8 + 5)/8 = 29/8 miles.

To find the remaining distance, we subtract 29/8 miles from 22/3 miles:

First, find a common denominator for the fractions, which is 24. Convert both fractions: 22/3 × 8/8 = 176/24 and 29/8 × 3/3 = 87/24.

Now subtract the distances: 176/24 - 87/24 = 89/24 miles.

Therefore, Arun has 89/24 miles left to walk to reach his friend's house.

Final answer:

You can use a number line to find the sum of -8.3 + 10.5 by marking both numbers on the line, moving left to the negative value, and then moving right by the positive value to find the sum.

Explanation:

To find the sum of -8.3 and 10.5 using a number line, you start by drawing a horizontal line and marking the positions of -8.3 and +10.5 on it. You then move from 0 to -8.3 as this is a negative number. To add 10.5, you move 10.5 units to the right. Because 10.5 is greater than 8.3, your final position will be to the right of zero which makes the sum positive.

Let's break down the steps:

Draw a number line with enough space to mark both -8.3 and +10.5.

Mark the point -8.3 on the left side of zero since it's a negative number.

From -8.3, move 10.5 units to the right because you are adding a positive number.

The point you land on is the sum of -8.3 + 10.5.

If you need to subtract numbers, change the sign of the number being subtracted and then add according to the rules of addition. For instance, to subtract 3 from 5, you would change 3 to -3 and then add: 5 + (-3) = 2.

Answer:

A

Step-by-step explanation:

1. Line l is cut by line a (let it be named a, because the figure doesn't show its name). Angles 1 and 6 are vertical, so they are congruent.

2.  Line m is cut by line a. Angles 3 and 8 are vertical, so they are congruent.

3. Parallel lines l and m are cut by transversal a. Angles 6 and 3 are congruent as alternate interior angles.

Hence,

[tex]3x+25=4x-17,\\ \\3x-4x=-17-25,\\ \\-x=-42,\\ \\x=42^{\circ}.[/tex]

4. The measure of angle 6 is

[tex]3x+25=3\cdot 42+25=126+25=151^{\circ}.[/tex]

5. Angles 6 and 2 are supplementary angles, so they add up to 180°:

∠2=180°-∠6=180°-151°=29°

190.18 is the average balance

Answer:

The answer is $190.18

Step-by-step explanation:

When we calculate the average daily balance, we total the balance from each day in the billing cycle and divide the total by the number of days in the cycle. Here the billing cycle is given for July that has 31 days.

Lets calculate each days amount.

Opening balance from 1st July to 7th July = $209.53

So, it is a total of 7 days; amount is [tex]209.53\times7=1466.71[/tex]

On 8th July a payment of $50 is made making the amount

[tex]209.53-50=159.53[/tex]

So, from 8th July to 15th July (8 days), the balance was $159.53 making a total of [tex]159.53\times8=1276.24[/tex] dollars

On 16th July a charge of $20 was added, so from 16th July to 23 July (8 days), the amount became = [tex](159.53+20)\times8=1436.24[/tex] dollars

On 24th July additional charge of $35 was added and the period it remained same was till 31st July, making it 8 days.

So, amount is = [tex]214.53\times8=1716.24[/tex] dollars

Now adding all the charges we get;

[tex]1466.71+1276.24+1436.24+1716.24= 5895.43[/tex] dollars

Now we will divide this by 31 days to get the average daily balance.

[tex]\frac{5895.43}{31}=190.175[/tex]  ≈ $190.18

Answer:

The population of 75 hours from now would be 40,000.

Step-by-step explanation:

The reason for this is because your initial number is 10,000 and when 25 hours pass by, your population would be 20,000. Another 25 hours pass by, and then your population would be 40,000. If you multiply 25 by 3, you will notice 75 hours have just passed, so your answer would be 40,000.

The population of a bacterial colony that doubles every 25 hours will increase exponentially. In this case, starting from a population of 10,000 bacteria, after 75 hours, we will have 80,000 bacteria. This demonstrates the concept of exponential growth commonly seen in bacteria.

The population of a bacterial colony that doubles every 25 hours follows an exponential growth model. This process is where the increasing rate is proportional to the current scope, leading to continued growth. If we start with a colony of 10,000, after 25 hours, we will have 20,000 bacteria. After another 25 hours, this will double again to 40,000. And after a final 25 hours, we double the number again to 80,000.

Here are the calculations:

This demonstrates the concept of exponential growth commonly seen in the bacteria populations. The growth rate increases over time due to the characteristic of bacteria to divide and reproduce, leading to a rapid increase in their numbers.

Answer:

Snowboard can be purchased for the lowest price from Store C offering 40% discount.

Step-by-step explanation:

We need to compare discounts of 3 stores and find the store selling snowboard lowest of them.

Store A: Sale of 30% off and a successive discount of 10% off.

The formula used for successive discount is = (x+y - xy /100)%

here x= 30 and y =10 so total discount is:

Total discount = ( 30 +10 - (30*10)/100)%

                       = (40 - 300/100) %

                       = (40 -3) % = 37%

Original price = $189.59

Discount offered = 37% of $189.59

                            = 37/100 * 189.59 = $70.15

Selling Price = Original price - Discount offered

                     = $189.59 - $70.15

                     = $ 119.44

Store B: Sale of 20% off and a successive discount of 20% off.

The formula used for successive discount is = (x+y - xy /100)%

here x= 20 and y =20 so total discount is:

Total discount = ( 20 +20 - (20*20)/100)%

                       = (40 - 400/100) %

                       = (40 -4) % = 36%

Original price = $189.59

Discount offered = 36% of $189.59

                            = 36/100 * 189.59 = $68.25

Selling Price = Original price - Discount offered

                     = $189.59 - $68.25

                    = $ 121.34

Store C: Sale of 40% off.

Original price = $189.59

Discount offered = 40% of $189.59

                            = 40/100 * 189.59 = $75.84

Selling Price = Original price - Discount offered

                     = $189.59 - $75.84

                    = $ 113.75

So, Store A Sale price is: $ 119.44

Store B Sale price is: $ 121.34

and Store C Sale price is: $ 113.75

So, Comparing them we found that snowboard can be purchased for the lowest price from Store C offering 40% discount.

Step-by-step explanation:

We have to treat those player selections as independent events, since one doesn't influence the other (the fact you chose Joe as a guard, shouldn't have an influence on who'll pick as center, unless there's bad blood between some players... but that's a whole other story).

So, how many ways to pick 2 guards from a selection of 4?  The order doesn't seem to matter here, since they don't specify for example that Joe can only play on the left side).  So, it's a pure combination calculation:

[tex]C(4,2) = \frac{4!}{2! * (4 - 2)!} = \frac{24}{2 * 2} = 6[/tex]

C(4,2) = 6.

How many ways to pick the 2 forwards from a group of 5?  Using the same calculation, we get:

C(5,2) = 10.

And of course, the coach has 3 ways to pick a center player from 3.

Then we multiply the possible ways to pick guards, forwards and center...

6 * 10 * 3 = 180 ways.
