The value of an autographed baseball from 2017 is $300. The value of the baseball exponentially increases by 5% each year after

WARRIOR [948]

General exponential equation
y = A(1+r)^x
where
A = initial value
r = rate increase (+) or decrease (-)
x = time period of the change
y = projected value

y = 300(1.05)^x
in this problem, x = years after 2017
we want to find an x that makes the value more than or equal to 650

650 <= 300(1.05)^x

A= 8x³ - 36x² + 54x - 27 A = ( ? x -?)³

Rashid [163]

Answer:

$(2x-3)^{3}$

Step-by-step explanation:

2x * 2x * 2x would get the 8x^3

the -3 * -3 * -3 would get the -27

if you do all the other multiplications -36x^2 and 54 X would result

Answer:

425 mm

Step-by-step explanation:

The ratio of compound A to compound B is 5 is to 6.

So, we can say that the total ratio is of 11 parts (5+6=11).

If the chemist wants a total of 935 mm of the drug, then each of the 11 parts are worth:

$\frac{935}{11}=85$

From the ratio, we know that Compound A is 5 parts. So:

$85*5=425$

425 mm of Compound A is needed.
