Answer:
b(t) = 36000·e^(0.12t)
Step-by-step explanation:
Continuous growth at a rate of r per time period is modeled by the exponential multiplier e^(rt), where t is the number of time periods. This value multiplies the initial amount (at t=0). In this case, the model would be ...
b(t) = 36000·e^(0.12t)
where b(t) is the number of bacteria in the colony after t time periods.
Find the slope of the line that passes through each pair of points.
A(-6,1) B(2,1)
Answer:
Slope = undefined
Step-by-step explanation:
Use the formula:
m = y2 - y1 / x2 - x1
Plug in the given information
m = 1 - 1 / 2 - - 6
Negative + Negative = Positive
m = 1 - 1 / 2 + 6
m = 0 / 8
m = 0/8
m = undefined

If A=D and C=F, which additional statement does NOT alloy you to conclude that ABC=DEF
Answer:
A
Step-by-step explanation:
i think its a because its saying which one does not allow you to conclude that both triangles are congruent but the other ones are talking the sides and a is the only one thats talking about the angles. so i dont really know if its right but thats just an educated guess.

A researcher has conducted a survey using a simple random sample of 50 licensed drivers to create a confidence interval to estimate the proportion of licensed drivers favoring the construction of a new stoplight. Assume that the sample proportion does not change. The researcher now decides to survey a random sample of 200 people instead of 50 licensed drivers. Which of the following statements best describes how the confidence interval is affected by this change?
The width of the new interval is about the same width as the original interval.
The width of the new interval is about twice the width of the original interval.
The width of the new interval is about one half the width of the original interval.
The width of the new interval is about one fourth the width of the original interval.
The width of the new interval is about four times the width of the original interval.
Answer: the answer is C.
Step-by-step explanation:
Answer:
Might be C?
Step-by-step explanation:
I got D. wrong (The width of the new interval is about one fourth the width of the original interval.)

How do i know this answer to this question ?? Joe has a total of 94 stamps in his stamp collection. He collected 27 in April and 34 in May. How many did he collect in June?
Answer:
Stamp collected in June = 33
Step-by-step explanation:
Total stamp = 94
Stamp collected in April = 27
Stamp collected in May = 34
Stamp collected in June = x
Total stamp = April stamp + May stamp + June stamp
94 = 27 + 34 + x
94 = 61 + x
x = 94 - 61
x = 33
Stamp collected in June = 33

Answer:
9x³-9x²+2x
Step-by-step explanation:
Let the expression be given as
(2-3x)(x-3x²)
Expand
= 2(x)-2(3x²)-3x(x)-3x(-3x²)
= 2x - 6x² -3x²+9x³
Rearrange
= 9x³-6x²-3x²+2x
= 9x³-9x²+2x
Hence the simplified form of the expression is 9x³-9x²+2x

What is the area of the smallest scalene triangle whose side lengths are prime numbers?
Answer:
area = 10.28 units²
Step-by-step explanation:
Smallest prime numbers I can think of is 2, 3 & 5 but that will not make a triangle.
3, 5, & 7 will
area = 1/2(7)(2.9375) = 10.28 units²
Julio had 20 minutes to do a three-problem quiz. He spent 11 1 4 minutes on question A and 5 4 5 minutes on question B. How much time did he have left for question C?
Answer:
2 19/20 minutes
Step-by-step explanation:
Julio had 20 minutes to do a three-problem quiz. He spent 11 1 /4 minutes on question A and 5 4 /5 minutes on question B. How much time did he have left for question C?
The total number of minutes =
Number of minutes spent doing question (A + B + C)
Hence,
Hence, the number of minutes he had left for Question C is calculated as:
20 minutes - ( 11 1/4 + 5 4/5) minutes
20 minutes - ( 11 + 5 ( 1/4 + 4/5))
Lowest common denominator = 20
20 minutes - ( 16 + ( 5 + 16/20)
20 minutes - ( 16 + 21/20) minutes
20 minutes - (16 + 1 1/20) minutes
20 minutes - 17 1/20 minutes
= 2 19/20 minutes
Therefore he had 2 19/20 minutes left for Question C

factorise p-q-x(q-p)
Answer:
(1 + x)(p - q)
Step-by-step explanation:
Given
p - q - x(q - p) ← distribute parenthesis by - x
= p - q - qx + px ← rearrange terms in p and terms in q
= p + px - q - qx ( factor first/second terms and third/fourth terms )
= p(1 + x) - q(1 + x) ← factor out (1 + x) from each term
= (1 + x)(p - q)
Which choice is equivalent to the product below for acceptable values of X?
sqrt(x+2)*sqrt(x-2)
Answer:
√x^2-4
Step-by-step explanation:
Given the expression
√(x+2) * √(x-2)
= √(x+2)(x-2)
Expand
= √x(x)-2x+2x-2(2)
= √x^2-4
Hence the product of the expression will give √x^2-4
For x to be acceptable x^2 - 4 = 0
x^2 = 4
x = ±√4
x = ±2
Acceptable value of x are values that are greater than or equal to ±2
Answer:
√x^2-4

Write a similarity statement for the triangles.
In Triangle CDE, C=60°, and D=53°. In Triangle FGH, F=60°, and H=67°
Answer:
The triangles are similar by Angle-Angle-Angle similarity
both triangles vertexes are 60°, 53°, and 67°
Step-by-step explanation:
Answer:
Step-by-step explanation:
ΔCDE ,
∠C + ∠D + ∠E = 180 {angle sum property of triangle}
60 + 53 + ∠E = 180
113 + ∠E = 180
∠E = 180 - 113
∠E = 67
ΔFGH ,
∠F + ∠H + ∠G = 180 {angle sum property of triangle}
60 + 67 + ∠G = 180
127 + ∠G = 180
∠G = 180 - 127
∠G = 53
∠C = ∠F
∠E = ∠H
∠D = ∠G
ΔCDE ~ ΔFGH ------ AA similarity

Jordan ran 15LaTeX: \frac{3}{8}3 8 miles, while Ethan ran 12 LaTeX: \frac{1}{6}1 6 miles. How many miles did the boys run altogether?
Answer:
27 13/24 miles
Step-by-step explanation:
Given that:
Jordan = 15 3/8 miles
Ethan = 12 1/6 miles
Miles ran altogether :
15 3/8 + 12 1/6
123/8 + 73/6
(369 + 292) / 24
= 661 / 24
= 27 13/24
