Question: write an equation for each parabola with vertex at the origin

Problem: through (3,2); symmetric with respect to the x axis

Answer:

y-intercept = 2/3

Slope = 0

Step-by-step explanation:

Equation of Line is y=mx+c

where m is the Slope

and c is the y-intercept

so for our Problem

y=2/3

which can be rewritten as y=0x+2/3 (y=mx+c)

so Slope =m=0

and y-intercept = c = 2/3

Answer:

Step-by-step explanation:

The sort of sequence it is can be determined by looking at the differences of n-values and the differences of t(n)-values. When the n-value differences are constant, the nature of the relation between the t(n)-values can tell you the kind of sequence.

Here, the n-values all differ by 1. The t(n)-value differences double with each increase in n. That is, they are 5 and 10. We notice also that the t(n) values double with each increase in n. We can fill the rest of the table using that relationship:

  t(n) = t(n-1) × 2 . . . . . each term is double the previous term

  t(4) = t(3) × 2 = 20 × 2 = 40

  t(5) = t(4) × 2 = 40 × 2 = 80

When the terms of the sequence have a common ratio, the sequence is geometric, and the function describing the sequence is an exponential function.

__

The general term of a geometric sequence is ...

  t(n) = t(1) × r^(n-1)

The table tells us the first term is ...

  t(1) = 5

And our observation above tells us the common ratio is r = 10/5 = 2. Then the equation of the sequence is ...

  t(n) = 5 × 2^(n-1)

__

See the attachment for a graph.

Answer:

a)   (4, 40) and (5, 80)

b)  [tex]t(n)=2.5 \cdot2^n[/tex]

c)  see attached

Step-by-step explanation:

As the value of t(n) doubles each time, we can conclude that this is an exponential function.

Therefore, the missing ordered pairs are (4, 40) and (5, 80)

General form of an exponential function:  [tex]y=ab^x[/tex]

where:

If [tex]b > 1[/tex] then it is an increasing function

If [tex]0 < b < 1[/tex] then it is a decreasing function

Given:

Substitute these ordered pairs into the general form of the exponential function:

Equation 1:   [tex]ab^2=10[/tex]

Equation 2:   [tex]ab^3=20[/tex]

Divide Equation 2 by Equation 1 to find [tex]b[/tex]:

[tex]\implies \dfrac{ab^3}{ab^2}=\dfrac{20}{10}[/tex]

[tex]\implies b=2[/tex]

Now substitute the found value of [tex]b[/tex] into one of the equations and solve for [tex]a[/tex]:

[tex]\implies ab^2=10[/tex]

[tex]\implies a\cdot 2^2=10[/tex]

[tex]\implies a=\dfrac{10}{4}[/tex]

[tex]\implies a=2.5[/tex]

So the final exponential equation is:  [tex]t(n)=2.5 \cdot2^n[/tex]

Graphing

Plot the points from the table

To find the y-intercept:

Substitute [tex]n = 0[/tex] into the equation:

[tex]\implies t(0)=2.5 \cdot2^0[/tex]

[tex]\implies t(0)=2.5[/tex]

Therefore, the y-intercept is at (0, 2.5)

Asymptote:  [tex]t(n) = 0[/tex]

Answer:

2286

Step-by-step explanation:

If you take 14 percent of a number and get 320, then what is that number? In other words, you know that 14 percent of a number is 320 and you want to know what that initial number is.

To solve this problem you multiply 320 by 100 and then divide the total by 14 as follows: (320 x 100) / 14

When we put that into our calculator, we get the following answer:

2285.71

can't have a portion of someone to you round it to the nearest whole number.

Answer:

The town’s population is 2286 (approximately)

Step-by-step explanation:

Let x be the number of the town’s residents :

We can translate the statement “14% of the town’s population is over the age of 65 and there are 320 residents over the age of 65” mathematically like this :

[tex]\frac{14}{100} x=320[/tex]

[tex]\Longrightarrow 14x=320\times 100\\\\\Longrightarrow 14x=32000[/tex]

[tex]\Longrightarrow x=\frac{32000}{14}[/tex]

[tex]\Longrightarrow x=2285.71428571429[/tex]

To meet the goal of $320.00 for the playground, they need to raise a total of $400.00

We know that for each $20 raised, they get $16 for the playground. They need to get $320.00 for the playground.

Taking the quotient:

N = $320.00/$16 = 20

This means that they need to raise $20 20 times, so they get $16 20 times which is equal to $320.

Then, we can conclude that they need to raise a total of:

Answer:

.053

Step-by-step explanation:

The decimal places go all the way out to the thousandths place. In order to properly compare all of the decimals, it's best to add zeroes in place of any empty decimal places in any of the numbers.

.5 would now be .500

.53 would now be .530

And the other two numbers are already in the thousandths place, so those don't need to be changed.

Now, we can put all the numbers next to each other and compare. You compare decimals the same way you compare normal numbers- just act as if the decimal points aren't there.

If the numbers were 500, 530, 053, and 503, we know that 053 would be the smallest number. Therefore, the decimal .053 is the smallest.

Answer:

a = 55

Step-by-step explanation:

1. Set up the equation: 0.2a = 11 (20% is equal to 0.2 because to convert a percentage to a decimal you divide it by 100. In math, "of" means "times" and "is" means "equals" so the equation is 0.2 x a = 11, which can be shortened to 0.2a = 11).

2. Divide both sides by 0.2. You will be left with a = 55.
