The answer is B) n+6. Simply because penny is 6 inches taller than Claire, which means you would have to add 6 inches to Claire's height to reveal penny's height. Also n represents Claire height which makes the expression easier to figure out.

Which ordered pair can be plotted together with these four points, so that the resulting graph still represents a function?

MrRissso [65]

Answer:

B.(-1,2)

Step-by-step explanation:

In a function, there can not be two different values of y corresponding to the same value of x.

See the graph attached.

Here, the points on the graph are (1,2), (2,-3), (-2,-2) and (-3,1).

If we consider point (-2,2) then there will be two points corresponding to the same x value i.e. (-2,-2) and (-2,2).

Similarly, if we consider the point (2,-2) or (2.-1) then also there becomes more than one values of y for a single value of x i.e. x = 2.

So, if we consider the ordered pair (-1,2) then only the graph still represents a function. (Answer)

A housewife deposited Rs 10,000 on saving account at 5% p.a. interest compounded

Naddik [55]

Answer:

Rs. 3923.08

Step-by-step explanation:

First principal invested = Rs. 10000

Interest rate = 5%

The interest is compounded yearly.

Time = 1 year

1 year compound interest is equal to simple interest.

Formula for simple interest:

$SI = \dfrac{PRT}{100}$

Interest on first sum = $\frac{10000\times 5\times 1}{100} = Rs\ 500$

Another sum is on fixed deposit 8% compounded half yearly.

Let the sum = Rs $x$

Formula for compound interest is given as:

$CI = P(1+\frac{R}{100})^T - P$

It is compounded half - yearly, therefore T = 2

$CI = x (1+\frac{8}{100})^2 - x\\\Rightarrow CI = x(1.08)^2-x = 0.1664x$

As per question statement:

$0.1664x - 500 = 152.80\\\Rightarrow x = \dfrac{652.80}{0.1664} = Rs\ 3823.08$
