The Lake of Distress is contaminated with flesh-eating bacteria!! The lake started with only
4 square feet infected, but as time has gone on, the bacteria are growing by a factor of 3
every hour. Assume that the relationship between hours and square feet of bacteria is
continuous.
What is the domain of the function in set notation?
Given:
The lake started with only 4 square feet infected.
The bacteria are growing by a factor of 3 every hour.
To find:
The domain for this situation.
Solution:
Initial value = 4 square feet
Growth factor = 3
Using exponential growth model, we get
[tex]y=ab^t[/tex]
where, a is initial value and b is growth factor.
So, square feet of bacteria after t hours is
[tex]y=4(3)^t[/tex]
Here, domain is set of values of time and range is square feet of bacteria.
Above equation is defined for all values of t but we know that, time cannot be negative.
As the relationship between hours and square feet of bacteria is continuous, therefore the value of t can be any real number greater than or equal to 0.
[tex]Domain=\{t|t\in R\text{ and }t\geq 0\}[/tex].
Therefore, the domain is [tex]\{t|t\in R\text{ and }t\geq 0\}[/tex].
Jose's batting average is 0.250 after 160 times at bat, which means he made a hit 40 of the times he was at
bat. He wants to improve his batting average to 0.333. If he makes a hit the next x times at bat, which
equation can be used to calculate the number of hits needed to obtain this improved batting average?
A. +40
160
.333
B.
160
= .333
2+40
C.
2+40
2+160
.333
O
D.
3+160
= .333
+40
Answer:
The correct option is;
[tex]\dfrac{x + 40}{x + 160} = 0.333[/tex]
Which is of the form of option C with 2 replaced by x and the characters formatted
Step-by-step explanation:
The given parameters are;
Jose's present batting average = 0.250
The number of times he was at bat = 160
The number of times he made a hit = 40
The batting average he wants to improve to = 0.333
If he makes a hit the next x times he was at bat is represented as if he makes a hit each time, for the next x time he was at bat. We have;
The number in times he makes a hit the next x times he was at bat = x
Therefore, we get;
New total number of hits Jose makes = 40 + x = x + 40
New total number of time Jose was at bat = 160 + x = x + 160
Therefore, given that Jose intends to improve his batting average to 0.333, and that the batting average is given by the relation;
[tex]Batting \ average = \dfrac{The \ number \ of\ hits}{The \ number \ of\ at \ bat }[/tex]
To find x, we have;
[tex]0.333 = \dfrac{x + 40}{x + 160}[/tex]
Therefore, the correct option is most likely C. where the 2 is supposed to be x.

Write in Slope Intercept form: x-3y=-15
Answer: Slope = 0.667/2.000 = 0.333
x-intercept = -15/1 = -15.00000
Step-by-step explanation: y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line x-3y+15 = 0 and calculate its properties
Notice that when x = 0 the value of y is 5/1 so this line "cuts" the y axis at y= 5.00000
y-intercept = 15/3 = 5
When y = 0 the value of x is -15/1 Our line therefore "cuts" the x axis at x=-15.00000
x-intercept = -15/1 = -15.00000
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 5.000 and for x=2.000, the value of y is 5.667. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 5.667 - 5.000 = 0.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 0.667/2.000 = 0.333
Slope = 0.667/2.000 = 0.333
x-intercept = -15/1 = -15.00000

Billy's Boat Rental Company charges a yearly fee of $105 and $9.50 each time a member wants to rent a boat. Lisa's Boat Rental Company does not charge a yearly fee, but charges $14.75 every time a member rents a boat. How many times does a person have to rent a boat for the cost to be the same amount at both rental companies?
Step-by-step explanation:
we can proceed to model the cost of Billy's Boat Rental Company
let y be the cost
let x be the number of rentals
y=105+9.5x----1
Also, the cost of Billy's Boat Rental Company
y=14.75------2
the question is "How many times does a person have to rent a boat for the cost to be the same amount at both rental companies"
we have to equate the two cost and solve for x
105+9.5x=14.75
105-14.75+9.5x=0
90.25+9.5x=0
9.5x=-90.25
divide both sides by 9.5 we have
x=-90.25/9.5
x=9.5

Simplify the expression. 1.7 – 2.7 – 1.34 + 4.9 – 1.48
explain im lost
Answer:
0.08
Step-by-step explanation:
1.7 – 2.7 – 1.34 + 4.9 – 1.48
2.7
- 1.7 (subtract 1.7 from 2.7)
--------
-1.0 [2.7 is greater than 1.7 and 2.7 is negative(in the ques) , therefore 1.0 is negative]
-1.0-1.34
we know that (-) (-) is (+)
therefore add -1.34 with -1.0
1.34
+ 1.0
-----------
-2.34 [since 1.34 is greater and it is negative]
-2.34+4.9
we know that (-)(+) is (-)
therefore subtract -2.34 from 4.9
4.90 ← (we put zero so that we can subtract without getting confused)
- 2.34
------------
1.56 [1.56 is positive because 4.9 is greater and it is positive]
1.56-1.48
here, digit before the decimal point is same but after decimal point .56 is greater than .48 therefore subtract 1.48 from 1.56
1.56
- 1.48
-----------
0.08
therefore, 1.7 – 2.7 – 1.34 + 4.9 – 1.48 = 0.08

Triangles
An isosceles triangle is a triangle with two equal sides. The angles the equal sides form with the third side are also equal.
The triangle shown in the figure is isosceles and the angles marked as '2' and 67° are equal. But we are also given that the angle '2' equals 8x+3, thus:
8x+3=67
Reducing:
8x=67-3=64
Solving:
x=64/8

Answer:
C ( x = 2 (multiplicity of 2), x = -2, x = -4)
A ( x = 5 (crosses), x = -3 (touches))
Step-by-step explanation:
Here are a couple of rules that helped me come to these answers.
1. When finding a zero, you flip the value inside of the parenthesis. For example (x + 2) would have the zero of x = -2.
2.The multiplicity of something is how many times the same zero is there. It is the exponent outside of the equation. For the first question, the (x - 2) has an exponent of 2, thus it has the multiplicity of 2.
3. The multiplicity determines whether the line just touches (or "bounces" off) the x axis or crosses the x axis. If the multiplicity is odd, it crosses the axis. If the multiplicity is even, it just touches the axis. A good way to remember this is with linear and quadratic equations. A linear is commonly know as only having an exponent of 1 (an odd) number and would cross the x axis. A quadratic equation has an exponent of two (an even number) so the line "bounces" on a graph.

A ribbon 105 centimeters long is cut into two pieces. One of the pieces is four times longer than the other. What is the length, in centimeters of the shorter piece
of ribbon?
Type your answer as the number ONLY.
Answer:
21 cm
Step-by-step explanation:
The two pieces have a length ratio of 1 : 4, so the shorter piece is 1/(1+4) = 1/5 of the total length.
105 cm/5 = 21 cm
The shorter piece is 21 cm.
