Answer:
1.98 × 10^10
Step-by-step explanation:
First solve for how many text messages were sent out per one month:
22,000,000 × 900
19,800,000,000
Convert into scientific notation:
1.98 × 10^10
In scientific notation, there can only be one number before the decimal. The rest of the numbers must be after the decimal; hence, why I put the numbers 9 and 8 after the decimal. If the rest of the numbers are zeros, you do not have to add them after the decimal. Instead, starting from right to left, count the number places until you reach your decimal. The number you have counted will be your exponent. I counted nine 0's, one 8, and one 9 which made this exponent 10 as there were 10 decimal placements.
The possible outcomes for the coin is 2 out of 1 since a coin has 2 sides the coin may only land on 1 side but the chances are between both sides having a 50/50 chance to land on either side.
Y=(m)(x)+b
so you already have the slope=-6/5 and the intercept is 3
y=-(6/5)x+3
Answer:
Step-by-step explanation:
Problem One
19 + 2*ln(x) = 25 Subtract 19 from both sides
19 - 19 + 2ln(x) = 25 - 19 Combine
2* ln(x) = 6 Divide by 2
ln(x) = 3 Take the inverse log
e^(ln(x)) = e^3 Reduce
x = 20.09
Problem 2
Getting this to graph in Desmos can be a bit of trouble. The correct format is y = abs(x^2 - 3x + 1). Knowing about abs and getting the quadratic to work are two separate [and difficult] problems.
The graph for this is below.
The answers (according to Desmos) are (2,1) and (3.4, 2.4). I think you should include D but that is a matter of opinion. I think it's a typo. Whoever made the question up may actually get that answer.
