Answer: I’m wasnt sure if u r supposed to round up. I assumed that we round down at the hundredth decimal cuz money. Also, make sure to include money signs when you write the numbers down.

A. 42.57

b. 50.96

C. 49.44

D. 63631.44

E. 127.05

F. 3805.49

G. 3.76

H. 2687.61

I. 9526.21

J. 3453.78

Step-by-step explanation:

A. 30 x 1.419= 42.57

B. 45 x 1.13250= 50.9625

C. 56/ 1.13250= 49.44812362

D. 478.90 x 132.87= 63631.443

E. 89.54 x 1.419= 127.05726

F. 5400/ 1.417= 3805.49682875

g. 500/ 132.87= 3.76307669

H. 4500/ 1.67435= 2687.61011735

i. 5689.50 x 1.67435= 9526.214325

J. 458904/ 132.87= 3453.78189207

A culture started with 3,000 bacteria. After 8 hours, it grew to 3,300 bacteria. Predict how many bacteria will be present after

Sav [38]

Answer:

$3,462\ bacteria$

Step-by-step explanation:

In this problem we have a exponential function of the form

$y=a(b^x)$

where

x is the time in hours

y is the numbers of bacteria

a is the initial value

b is the base

r is the rate of growth

b=(1+r)

we have that

$a=3,000\ bacteria$

For x=8, y=3,300

substitute in the exponential function

$3,300=3,000(b^8)$

solve for b

$1.1=(b^8)$

$b=\sqrt[8]{1.1}$

$b=1.0120$

Find the value of r

$r=b-1=1.0120-1=0.0120=1.20\%$

The equation is equal to

$y=3,000(1.012^x)$

For x=12 hours

substitute the value of x in the equation

$y=3,000(1.012^{12})$

$y=3,462\ bacteria$

4 more than the quotient 12 and a number x

snow_tiger [21]

More than means to add.

Quotient means to divide.

4 + (12/x)

what does y =mx +b mean and how do you use it to solve problems? whats the different between y=mx+b and y=mx + c

algol13

y=mx+c is the equation for a line graph, m is the gradient and c is where it goes through the y axis, the only difference between y=mx+c and y=mx+b is where u live as in different countries learn it different ways but it is still the same thing

Given 100,000 cm = 1 km Evaluate 17.8km

inn [45]

Hi there!

In order to solve this equation, we need to multiply:

17.8 * 100,000 = 1,780,000 cm
Since 100000 cm = 1 km, 17.8 km = 1,780,000 cm

Hope this helps!
