13. Which of the following is the graph of y = 3(1⁄5)x?

Answers

Answer 1

Answer:

Answer:

Second graph

Step-by-step explanation:

The second graph is the correct one. Why? because the y intercept is (0, 3), and also because the base, 1/5, is between 0 and 1, which leads to a decaying exponential graph.

In this case, all letters are unique.

Start by holding the first letter:
E - XAM
E - XMA
E - MAX
E - MXA
E - AXM
E - AMX
So there are 6 combinations here.

Repeat for all 4 letters.

6 x 4 = 24

This is same as 4x3x2x1.

For 3 unique characters, it is 3x2x1.
For 5 unique characters, it is 5x4x3x2x1

$1400 from fund-raisers in a 18-month CD paying 3.7%

Answers

Answer:

The junior class will receive US$ 1,479.77 when it cashes in the Certificate of Deposit.

Step-by-step explanation:

1. Let's review the data given to us for answering the question:

Amount invested in the Certificate of Deposit = US$ 1,400

Duration of the CD = 18 months

Interest rate = 3.7% compounded monthly

2. Let's find the future value of the Certificate of Deposit after 18 months, using the following formula:

FV = PV * (1 + r) ⁿ

PV = Amount invested = US$ 1,400

number of periods (n) = 18

rate (r) = 3.7% = 0.037 annually or 0.003083 monthly

Replacing with the real values, we have:

FV = 1,400 * (1 + 0.003083) ¹⁸

FV = 1,400 * (1.003083) ¹⁸

FV = 1,400 * 1.056978

FV = US$ 1,479.77 (Rounding to the nearest cent)

The junior class will receive US$ 1,479.77 when it cashes in the Certificate of Deposit.

The graph shows Linda's math scores versus the number of hours spent doing math homework.What will most likely be Linda's approximate math score if she does math homework for 7 hours a week?

A. 62.5 Points

B.77.5 Points

C. 82.5 Points

D.93.5 Points

Answers

Answer:

The approximate score is:

Option: A

A. 62.5 points.

Step-by-step explanation:

Clearly from the graph we could observe that the line of best fit passes through (0,10) and (4.5,45).

Now we find the equation of line of best fit with the help of formula that is used to find the equation of a line passing through (a,b) and (c,d) as:

$y-b=(d-b)/(c-a)* (x-a)$

Here we have:

(a.,b)=(0,10) and (c,d)=(4.5,45)

Hence, the line of best fit is given as:

$y-10=(45-10)/(4.5-0)*(x-0)\n\ny-10=(35)/(4.5)* x\n\ny-10=(70)/(9)* x\n\ny=(70)/(9)* x+10$

Now we are asked to find the math score if she does math homework for 7 hours a week i.e. we have to find the value of y when x=7.

Hence, we put x=7 in the equation to obtain y as:

$y=(70)/(9)* 7+10\n\ny=(490)/(9)+10\n\ny=64.44$

Hence, the approximate score is:

Option: A

A. 62.5 points.

Answer=A

Let's write the an equation in slope intercept for for the line.

y-intercept=10

slope=rise/run=15/2=7.5

equation:

y=mx+b
y=7.5x+10

Solve for x=7

y=7.5(7)+10
y=52.5+10
y=62.5

Answer=A
