The answer is <span>C.) 2
The general form of formula is
y = a </span><span>• r^x
y - the total number of bacteria after x period of time
a - the initial number of bacteria
r - growth rate
x - period of time
Let's compare:
</span>y = a • r^x
<span>y = 280 • 2^x
Since r = 2, the growth rate is C.) 2</span>
Answer: The equation is true
Step-by-step explanation:
Since x=3 and y= 5
Substitute the values for x and y
y=2x-1
5=2(3)-1
5=6-1
5=5
⇒The equation is true
To calculate the distance between two points, you have to use the distance formula.
point 1 is (-5, -8) and point 2 is (-1, -16). The x coordinate is before the comma and the y coordinate is after the comma.
The distance formula is:
Distance =
Insert your coordinates into the formula.
Combine your terms.
Square your numbers.
Add these terms together.
Your answer is or 8.94
Answer:
C and D
Step-by-step explanation:
both the squareroot of 19 and 23 are irrational because their square toots have decimals that go on infinately
Radius times 2 = diameter which would be 10 times 3.14 is 31.4 so it’s 31.4
