Mary Moneypenny went to her bank each week and opened a club account. She deposited $21.75 per time period. If she made 12 deposits before interest was credited, how much would she have deposited before interest was credited?The balance would be $ before interest was credited.

Answers

Answer 1

Answer:

Answer:

$261

Step-by-step explanation:

We are given that Mary Moneypenny went to her bank each week and opened a club account.

She deposited money per time period=$21.75

She made total deposits before interest was credit=12

We have to find out total deposits money in her account before interest was credited.

We are multiplying number of deposits with deposit per time period to obtain the value of total deposits

She would have total deposit money before interest was credit= $12* 21.75$ =$261

Hence, the balance would be $ 261 before interest was credited.

Answer 2

Answer: $21.75 x 12 deposits = $261

Find f(x) and g(x) so the function can be expressed as y = f(g(x)).
y =2/x^(2) + 3

Answers

We are asked to find f(x) and g(x) so the function can be expressed as y = f(g(x) such that y = y =2/x^(2) + 3. There are many possibilities here but we go to the simplest ones. we can have g (x) = x2 and f(x) is equal to 2/x + 3.

One possible answer is:

f(x) = (2/x) + 3 and g(x) = x².

Explanation:

We are to write this equation as y = f(g(x)). This means we want it to be a composite of functions; in f(x), we take the value of g(x) and use in place of x.

If we let g(x) = x², this means everywhere we see an x in f(x), we will replace it with x². To make our equation y = 2/x² + 3, working backward we would substitute x for x²; this would give us f(x) = 2/x + 3.

I'd seriously appreciate it if anyone could help ASAP! I'm giving Brainliest!The point (-6, y) lies on the graph of the equation: 5y=2x−4.

What is the value of y?

- $(5)/(16)$

$(5)/(16)$

$(16)/(5)$

- $(16)/(5)$

I believe it is $(5)/(16)$ but I'm not sure.

Answers

Answer:

- 16/5

Step-by-step explanation:

We have point with coordinates (-6, y) which lies ( or belong) on the graph of the straight line 5y=2x-4

When we replace x= -6 in given equation we get 5y = 2·(-6)-4 => 5y= -12-4 =>

5y= - 16 => y= - 16/5

Two bicyclists leave the center of town at the same time. One heads due north and the other heads due west. Later, the two cyclists are exactly 25 mi apart. The cyclist headed north has traveled 5 mi farther than the cyclist going west.How far has the cyclist going west traveled?

Answers

Answer:

Distance traveled by bicyclist traveling west = 15 miles

Step-by-step explanation:

These two cyclists travel at angle 90°

Relative displacement can be calculated using Pythagoras theorem.

Let d be the distance traveled by bicyclist traveling west

Distance traveled by bicyclist traveling north = d + 5

$25^2=d^2+(d+5)^2\n\nd^2+d^2+10d+25=625\n\n2d^2+5d-600=0\n\nd^2+5d-300=0\n\nd=(-5\pm √(5^2-4* 1* (-300)))/(2* 1)\n\nd=(-5\pm √(25+1200))/(2)\n\nd=(-5\pm √(1225))/(2)\n\nd=(-5\pm 35)/(2)\n\nd=15miles\texttt{ or }d=-20miles$

Negative displacement is not possible.

Hence d = 15 miles

Distance traveled by bicyclist traveling west = d = 15 miles

This situation is represented in annex.
From Pythagorean theorem you've got equation:
$x^2+(x+5)^2=25 \n \n \hbox{From formula} \ \ \ (a+b)^2 = a^2+2ab+b^2: \n \n x^2+x^2+10x+25=25 \n 2x^2+10x=0 \n \n \hbox{Factor out} \ \ 2x: \n 2x(x+5)=0 \n \n \hbox{So you've got:} \n \n x_1=0 \n x_2=-5$

There isn't any solutions where x>0, so this situation is IMPOSSIBLE.

the Mclntosh family went apple picking. they picked a total of 115 apples. The family ate a total of 8 apples each day. after how many days did they have 19 apples left?

Answers

In the given question, all the information's that are required is already provided. based on these information's the correct answer can be easily deduced. The McIntosh family picked a total of 115 apples. the family ate a total of 8 apples per day. It is required to find the day after which there will be 19 apples left from the total of 115. Then firstly let us subtract 19 apples from the total of 115.
Number of apples left after deducting 19 apples = 115 - 19
= 96
Now
8 apples are eaten by the McIntosh family in = 1 day
96 apples will be eaten by the McIntosh family in = 96/8
= 12 days
So after 12 days, 19 apples will be left with the McIntosh family.

Answer:

19 apples will be left with the McIntosh Family
