Ken and Vincent each want to run for president of their school's student body council. In
order to do so, they must collect a certain number of signatures and get a nomination. So far,
Ken has 10 signatures, and Vincent has 30. Ken is collecting signatures at an average rate of
3 per day, whereas Vincent is averaging 2 signatures every day. Assuming that their rate of
collection stays the same, eventually the two will have collected the same number of
signatures. How long will that take?

Answer:

Step-by-step explanation:

I think this is a very essential question to ask. While a lot of people want shortcuts to get things done(i used to too, when I was a student), shortcuts doesn't always cut it short. The reason is just as simple as that of any other subject that deals with theory.

Learning the limit definition gives ample knowledge about how the whole derivation works in general. Yes, quite alright, you can get the basic differentiation done when you don't learn that, but as someone who has gone far in calculus, I'd tell you for free, a time will come during computation where you'd get stuck because you never had that prior knowledge of definition.

Further along the line in calculus, you would be doing derivatives where you'd have to apply your knowledge of the definition of limit, and how would you be able get that done if you hadn't already learnt it?

Exactly!

Answer: Yes

These numbers are a proportion. Let me show an example:

Jenna reads 93 pages of a book in 15 pages. How many pages does she read in 10 minutes?

93 ÷ 15 = 6.2

6.2 x 10 = 62

Answer: She reads 62 pages in 10 minutes.

These numbers can show a proportion like the example listed.

Hope this helps you!

Answer: yeah, sure

93 divided by 15 = 6.2

6.2 x 10 = 62

Answer:

13 hours, 33 minutes, 20 seconds

Step-by-step explanation:

The swimming pool will hold 1.22 million cubic inches of water, and if it fills up at 1500 cubic inches per minute, it will take 813 minutes and 20 seconds to fill the pool, which means that in simplest form, that will be 13 hours, 33 minutes, and 20 seconds.

Answer:c

Step-by-step explanation:

The measures of the angles in triangle ABC are; m∠A ≈ 73.7°, m∠B ≈ 16.3°, m∠C ≈ 90°

It follows that the right angle is between the two shorter sides;

On this note, the angle, m∠A is opposite side BC;

Therefore, from sine formula;

m∠A ≈ 73.7°

And from sum of angles in a triangle;

m∠A ≈ 16.3°

I think it would go up on the scale.

Step-by-step explanation:

I believe it would go up, because think about air in your mouth. If you close your mouth and add more air, your mouth gets heavier to carry. Therefore, the air needs to go somewhere. Same with carbonated soft drinks, like soda.

Step-by-step explanation:

Answer: She needs 6 packs of cookies and  5 packs of coffee sachets.

Step-by-step explanation:

Cookies: come in packs of 10

Coffee sachets: come in packs of 12.

Sally wants to sell them in groups of 1 cookie and 1 coffee sachet, then we need to find a common multiple of 10 and 12. (the smallest one in this case).

To find the smallest common multiple, first let's find the largest common factor between 10 and 12.

If we write the numbers as a product of prime numbers, we have:

10 = 2*5

12 = 2*3*3

The only common factor is 2.

Then the smallest common multiple between 10 and 12 is equal to the product of 10 and 12 divided by the largest common factor between them, in this case is 2.

M = 10*12/6 = 60

Now to find the number of packages of each thing that she must buy, we need to divide 60 by the number of elements in each pack.

Cookies: 10 per pack

60/10 = 6

She needs 6 packs of cookies

Coffe: 12 per pack

60/12= 5

She needs 5 packs of coffee sachets.

Answer:

The answer is 53.3333333

Step-by-step explanation:

first you know that the speed on the way there is 40 mph and the back is 80

lets call the time x On the way there the time would just be X on the way back it would be x-1 because it took one less our

to calculate the distance you need to do speed times time therefor the distance on the way there would be 40x and the way back would be 80x-80

Then I made an equation 40x=80x-80 X=2

so the distance would be 80 miles but to find average speed you need to do total distance over total time so it would be 160 over 3 because the time is 2x-2 x=2 so thats 3

Answer: A C E

Step-by-step explanation:

y = -1x-2 is the perpendicular line of the given line y - 1 = {(x+2).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The product of slope of perpendicular lines will be equal to minus one.

y-1=x+2 the line has a slope of +1.

The slope of the perpendicular line will be -1.

y = -1x-2 is the perpendicular line of the given line y - 1 = {(x+2).

Hence,  y = -1x-2 is the perpendicular line of the given line y - 1 = {(x+2).

Answer:

This might be the answer- x=−8  y=−13

Step-by-step explanation:

Answer:

x = 2.66 repeating or 2[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

substitute y for x - 5

y = 2x + 3

x - 5 = 2x + 3

subtract 3 from both sides of the equation

x - 5 - 3 = 2x

x - 8 = 2x

subtract x from both sides of the equation

-8 = 2x - x

-8 = -3x

divide both sides of the equation by -3

-8/-3 = x

2.66 repeating = x

Answer && Step-by-step explanation:

We know f(x) transcribes towards -x axis. thus ruling out b and d (remember signs opposite of what they mean on the board, you would think +# =towards x axis and vice versa also note if multiplied by a negative on the outside, flips signs inside)

choosing A.

plug in values of -x to see if you can get ~= to graph so -5 to -1

x: -5, -4, -3, -2, -1

y: -2, -.25, 0, .25, 2

checks out., A is your answer

The equation for f(x) is F(x) = 1/4(x+3)²

Given is a graph, showing the function g(x) = x³, we need to find the equation for the function f(x) in the graph,

We know f(x) transformed towards x-axis.

We see that, there is a left shift of 3 units, so the function will be (x+3)³

Also, the graph is spread out 4 units, so the function can be 1/4(x+3)³

Hence, the equation for f(x) is F(x) = 1/4(x+3)²
