Does the function model exponential growth or decay? f(t)=1/4⋅4^t

Mathematics
1 answer:
yarga [219]3 years ago
6 0

Answer:

This is an exponential decay

Because the base of the exponent is 1/4.4 which is less than 1

Step-by-step explanation:

What is exponential growth?

when the base of our exponential is bigger than 1, which means those numbers get bigger.

What is exponential decay?

when the base of our exponential is in between 1 and 0 and those numbers get smaller.

A computer costs £927 plus VAT, where VAT is charged 20% find the total cost of the computer
liubo4ka [24]

A computer costs 927 plus VAT where VAT is 20%. We need to find the total cost of the computer.

The total cost = original cost + VAT

Total Cost = 927 + 20% * 927

20% converts to decimal by moving the decimal 2 units up, so it is 0.2

= 927 + 0.2*927

Multiply to find value of tax

= 927 + 185.4

Add to find the total cost

Total cost = 1112.4 euros

The diagram shows one way to develop the formula for the area of a circle. Pieces of a circle with radius r are rearranged to cr
IRINA_888 [86]

Answer:

A = 1/2(2πr)(r)

Explanation:

The circumference of the circle, 2πr, is the measure completely around the circle.  When the pieces of the circle are rearranged, half of this circumference will be on the top of the parallelogram and half will be on the bottom.  This means the base will be 1/2(2πr).

The approximate height of the parallelogram is the radius of the circle; this makes the area

A = 1/2(2πr)(r)
