What I can’t read the problems
What you must do is evaluate the function for the given conditions and thus be able to find the constants A and k
25 = Ae ^ k (2005)
31 = Ae ^ k2010
We then have two equations with two unknowns.
Solving.
25/31 = e ^ k (2005-2010)
Ln (25/31) = k (2005-2010)
k = Ln (25/31) / (2005-2010) = 0.043
Substituting k in any of the equations:
25 = Ae ^ (0.043 * (2005))
Clearing A
A = 25 / (e ^ (0.043 * (2005))) = 9.02E-37
Then, by 2020
P = (9.02E-37) e ^ (0.043 * (2020)) = 48 million
answer
the population for 2020 will be 48 million
Answer:
C. x^2+2x-10
Step-by-step explanation:
Volume of a Rectangular Prism = LWH
We have the height so we can simplify by dividing it out of the total volume
Then you get x^2+2x-10.
Since the area of the base is LW, that is your answer
Answer:
126°
Step-by-step explanation:
<u>Circle Theorem vocabulary</u>
- <u>Chord</u>: a straight line joining two points on the circle.
- <u>Inscribed angle</u>: the angle formed (vertex) when two chords meet at one point on a circle.
- <u>Arc</u>: the curve between two points on the circumference of a circle
- <u>Intercepted arc</u>: the arc that is between the endpoints of the chords that form the inscribed angle.
<u>Inscribed Angle Theorem</u>
The measure of an <u>inscribed angle</u> is half the measure of the <u>intercepted arc</u>.
Therefore:
Answer: the lower limit is 1.555g and the upper limit is 1.564g
Step-by-step explanation:
a mg is:
1mg = 0.001g
Then we need to look at the third digit after the decimal point.
Then the weight 1.56g is rounded around this.
Remember that if the third digit after the decimal point is 5 or bigger, then we round up.
if the third digit is smaller than 5, then we round down.
Now, the maximum possible value of this weight is when the third digit is equal to 4 (4 mg) where because it is smaller than 5, we round it down to 1.56g
Then the maximum is 1.564g
And the minimum value is when we have:
w = 1.555g
Because the third digit is a 5, we round it up to 1.56g.
So the lower limit is 1.555g and the upper limit is 1.564g
