Technology required. Priya starts with $50 in her bank account. She then deposits $20 each week for 12 weeks.
a. Write an equation that represents the relationship between the dollar amount in her bank account and the number of weeks of saving.
b. Graph your equation using graphing technology. Mark the point on the graph that represents the amount after 3 weeks.
c. How many weeks does it take her to have $250 in her bank account? Mark this point on the graph.
The given problem is about a person named Priya who started with $50 in her bank account and deposited $20 each week for 12 weeks. We need to find out after how many weeks she will have $250 in her bank account and also plot the given data on a graph, given that technology is required.Let's solve the given problem step by step:a) We can represent Priya's bank account after n weeks as follows:$50 + $20n
This is because she started with $50 and deposited $20 each week for n weeks.Now, to graph this equation, we can use any graphing calculator or software.
For example, we can use the Desmos Graphing Calculator, which is free and available online.To plot the given data, we need to set the domain as {0, 1, 2, 3, ..., 12} (for 12 weeks), and the range as {50, 70, 90, 110, ..., 290} (according to the equation). Then we can plot the points as follows:
After plotting the points, we can connect them with a straight line to get the graph of the equation.$$$$b)
To mark the point that represents the amount after 3 weeks, we need to find the value of the equation for n = 3, which is:$50 + $20(3) = $110This means that after 3 weeks, Priya will have $110 in her bank account.
We can mark this point on the graph as follows:$$$$$c) To find out after how many weeks Priya will have $250 in her bank account, we need to solve the following equation:$50 + $20n = $250Subtracting $50 from both sides, we get:$20n = $200Dividing both sides by $20, we get:n = 10
This means that after 10 weeks, Priya will have $250 in her bank account. We can mark this point on the graph as follows:$$$$$Therefore,
we can conclude that it will take Priya 10 weeks to have $250 in her bank account, and we can represent this data on a graph using graphing technology.

[a] Answer: y = 20x + 50
Step-by-step explanation:
We can write a linear equation to answer this part. Priya starts with $50 and adds $20 every week. Let y be the total amount of money in the bank account and x be the number of weeks passed. We will write a slope-intercept equation, where 20 is the slope and 50 is the y-intercept.
y = 20x + 50
[b] Answer: (3, 110)
Step-by-step explanation:
Next, we will use a graphing calculator as asked. Here I am using Desmos Graphing Calculator, it is free to use and online. We can type in our equation above, y = 20x + 50. See attached. Since she will not have negative weeks that she deposits, and she only deposits for 12 weeks, we will add {0 ≤ x ≤ 12} to our equation when we graph.
Since x is the number of weeks passed, 20(3) + 50 = 110, giving is the point (3, 110).
[c] Answer: 10 weeks
Step-by-step explanation:
Now, we need to find the point where she has $250 in her bank account. Since y is the total amount of money in her bank account, we can find where y = 250 on the graph.
This is at (10, 250), or 10 weeks.
98.37% as a decimal exsplain
Answer:
.9837
Step-by-step explanation:
to go from decimal to percentage, you would multiply by 100 or move the decimal point two to the right. so, to move from percentage to decimal, you would divide by 100 or move the decimal two to the left.
98.37% = .9837
Answer:
To convert from a percent to a decimal, you divide the percent # by 100 and take the % off. So therefore, 0.9837!!

Find the rate of change of the function by using two points from the table. Write in the simplest form.
x 2 4 6 8
y 5,8,11,14
Rate of change of given points is 3/2.
Given that
The values of x and y,
x values are 2, 4, 6, 8 and
y values are 5, 8, 11, 14.
To find
Rate of change = ...?
So, according to the question
we have,
The values of x = 2, 4, 6, 8
The values of y = 5, 8, 11, 14.
We know that,
Rate of change = (change in y )/(change in x)
= [tex]\frac{8-5}{4-2}[/tex]
= [tex]\frac{3}{2}[/tex]
The difference of other points are same, so the rate of change of given coordinates is 3/2.
Rate of change = 3/2

Rewrite the expression 18 with an
exponent.
Express the number 100 as a product of its prime factors.
Answer:
So, the prime factors of 100 are written as 2 x 2 × 5 x 5 or 22 x 52, where 2 and 5 are the prime numbers. It is possible to find the exact number of factors of a number 100 with the help of prime factorisation. The prime factor of the 100 is 22 x 52. The exponents in the prime factorisation are 2 and 2.
Step-by-step explanation:
Answer:
The prime factorization of 100 is 2 * 2 * 5 * 5. Using exponents, this number can also be written as 2^2 * 5^2.

He made a Venn diagram using the properties of the quadrilaterals, comparing those with four equal side lengths (E) and those with four right angles (R). Circles E and R overlap. Circle E contains 3, circle R contains 6, and the intersection contains 2. Number 9 is outside of the circles. Given that a randomly chosen quadrilateral has four right angles, what is the probability that the quadrilateral also has four equal side lengths? Express your answer in percent form, rounded to the nearest whole percent. 25% 33% 40% 67%
Answer:
A. 25%

The probability that the quadrilateral has four equal side lengths, given that the quadrilateral has four right angles is 25%
What are quadrilaterals?Quadrilaterals are shapes that have four sides; these four sides may or may not be:
ParallelCongruentCheck below on how to determine the probability
From the question, we have the following parameters:
n(E) = 5n(R) = 8n(E and R) = 2None = 9n(U) = 20The probability that the quadrilateral has four equal side lengths, given that the quadrilateral has four right angles is calculated using:
P(E | R) = n(E and R)/n(R)
This gives
P(E | R) = 2/8
Express as percentage
P(E | R) = 25%
Hence, the probability is 25%

Jordan is starting to save $150 to buy a new cell phone. In December, he saved $5. In January, he plans twice as much as he did in December, for a total savings of $15 ($5 + $10). If Jordan continues to save twice as much he saved from the previous month, in which month will his total savings will be enough to buy the phone.
Answer: At the Month May Jordan as able to get enough money to buy the phone.
Work:
December:$5
January:$10
February:$20
March:$40
April:$80
May:$160 <--Answer
____________________________________________________________In the problem Jordan saves $5 at December, then at January Jordan saved $10 which is twice as December's saved money amount. February, Jordan saved $20, which is twice as January's saved money amount. March is $40, which is twice as February's saved money amount. For April it is $80, which is twice as March's money amount, May is $160 which is twice as April's money amount. Or another way to say this is by starting at $5. Then, keep multiplying by 2 for each month until you get $150 or more. When you do, stop at the month that gets you $150 or more. When i did this exact method, I got $160 on the Month of May. $160 is more than enough for Jordan to buy his phone. So the month May is the correct answer where Jordan can get enough money for his phone.
Answer: The fifth month; By April Jordan would have saved more than enough to buy a new phone.
Step-by-step explanation:
Dec $5
Jan $10
Feb $20
Mar $40
Apr $80
Dec + Jan = $15($5+$10)
Dec+ Jan + feb = $35($5+$10+$20=$35)
Dec+ Jan + feb + mar = $75 ($5+$10+$20+$40=$75)
Dec+ Jan + feb + mar + apr = $155
