Answer:

f(x)=500+60x

So, B.

Step-by-step explanation:

Opening balance =500

Deposits= 60__ monthly

Write as a function

Represent the number of months with x and the balance at any month with f(x)

f(x) is calculated as thus:

Opening Balance + Deposits * Number of Months

So, we have:

f(x)=500+60*x

So, f(x) = 500+60x

Answer:

1) 19200- for Aarati 2) 17280- for Aakriti

Step-by-step explanation:

1. 16000/100*20=3200- THE MONEY WHICH ARE THE PROFIT,

2. 16000+3200=19200- THE PRICE for Aarati

3. 100-10=90 PERCENTS - the price for AAkriti contains from the price from Aarati

4. 19200*(90/100)= 17280- the price for Aakriti

Fine the area of the shaped trapezium in the rectangle below

Ksenya-84 [330]

At first find the area of rectangle:
(x + 4)*(x + 1) = x^2 + 5x + 4
Then find the area of triangle:
$\frac{(x+1)(x-3)}{2} = \frac{x^2-2x-3}{2}$
Then you must do like this
Area of rectangle - Area of triangle = Area of the shaded
x^2+5x+4 - ( $\frac{x^2-2x-3}{2}$ )

PLS HELP ASAP. QUESTION IN PICTURE

Anuta_ua [19.1K]

Answer: 50 degrees

Step-by-step explanation:

This is actually quite simple using the exterior angle theory

"The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle"

In this case the exterior angle is 120 degrees, basically what the theorem states is that it the angle that you see outside the triangle equals the angle measurements of the 2 angles opposite of it, so just create an equation because you know 2 of the variables

120=70+x

120-70=x

Angle x = 50 degrees
