Identifiy the initial amount a and the decay factor b in the exponential function y=5×0.5^×

xenn [34]

Answer:

$a=5\\ \\b=0.5$

Step-by-step explanation:

Given the exponential decay function $y=5\cdot (0.5)^x$

When $x=0,$ then

$y=5\cdot (0.5)^0=5\cdot 1=5,$

so the initial amount is $a=5$

The exponential decay function $y=a\cdot b^x$ has the decay factor $b.$

In your case, the eexponential decay factor is $b=0.5$

Answer: 27 candles.

Step-by-step explanation:

A rectangular prism has a volume calculated by length x width x height.

In this case, the candles have a volume of 220 cm³.

If the company used 5940 cm³ of wax, to find how many candles they made, you just divide them:

$5940 / 220 = 27$

You get 27 candles.

Bingo uses the numbers 1-75. If you randomly select a number, what is the probability it will not be a multiple of ten? Explain

ValentinkaMS [17]

Multiples of ten are: 10, 20, 30, 40, 50, 60, & 70.

So there are (7 options that ARE multiplies of ten) out of (75 total options)

Thus, there are (75 - 7 options that are NOT multiples of ten) out of (75 total options).

Answer: $\frac{68}{75}$
