Answer:

f(1)=-4

Step-by-step explanation:

For finding out f(1), we have to find the value of y coordinate of the point where its x coordinate is 1.

From the given graph, the point (1,-4) lies on the graph and has x coordinate as 1.

Drawing a vertical line x=1, it meets the graph at (1,-4)

Therefore, f(1)=-4

3. What is wrong with the following statement? If d/e = f, then d multiplied by f = e.f should be divided by e.F and e should be
Molodets [167]

the initial statement is:

\frac{d}{e}=f

and then:

d\cdot f=e

So the second statement is false because f should be multiply by e, not by d so is option C)

Principal = 5300=5300 rupees
PSYCHO15rus [73]

Answer:

Using the formula:

A=P+I

where

A is the total amount

P is the principal

I is the Simple Interest

As per the statement:

Principal(P) = 5300 rupees.

rate of interest(r) = 6.5% = 0.065

Total amount(A) = 6678 rupees.

Then using above formula we have;

6678 = 5300+I

Subtract 5300 both sides we get;

1378 = I

or

I = \$1378

We have to find the time period.

Using formula of Simple interest:

I = Prt

where r is the rate of interest (in decimal)

here, r = 6.5% = 0.065

Substitute the given values top find t:

1378 = 5300 \cdot 0.065 \cdot t

⇒1378 = 344.5t

Divide both sides by 344.5 we have;

4  = t

Therefore, the time period t in years is 4 years
