The domain of the function C(t) is R - { -5. -2}.
What is a domain?The domain of a function is the set of all values for which the range of the function is defined.
To achieve an immediate response to a particular drug's effects the concentration, C, in mg/L, of a particular medication after being injected into a patient is given by the function
C(t) = [tex]\frac{-18t^2 + 54t}{t^2 + 7t + 10}[/tex] where t represents time in hours.
We know that a function is undefined when its denominator becomes zero.
∴ We have to factor the quadratic equation t² + 7t + 10 which is,
t² + 5t + 2t + 10 = 0.
t(t+5)+2(t+5) = 0.
(t+5)(t+2) = 0.
So, t = -5 or t = -2 are the two values of this equation which makes the function c(t) undefined.
∴ The domain of the function [tex]\frac{-18t^2 + 54t}{(t+5)(t+2)}[/tex] is all real numbers except -2 and - 5 which can be written as
Domain of C(t) is R - { -5, -2}, where R represents all real numbers.

A function that represents the meters Jackie can run in any given minutes is b = 150m.
The meters she would run after 12 minutes is 1,800 meters.
How many meters can she run in 12 minutes?The independent variable is the variable that cannot be altered in the process of an experiment. The independent variable is the minutes ran by Jackie.
The dependent variable is the variable that is being measured in an experiment. It is usually affected by the independent variable. The dependent variable is the total distance that Jackie runs.
The function that represents the distance run is:
Total distance = distance run per minute x number of minutes
b = 150 x m
b = 150m
Distance run in 12 minutes = 150 x 12 = 1800 meters

Where is the point (-3,1) located when it is translated four units left and two units up 
Answer:
-5,3. You crawl before you can walk.
Step-by-step explanation:
Answer:
(-7, 3)
Step-by-step explanation:
Original point: (-3, 1)
So original x = -3
4 units left means x coordinate is decreased by 4
So, new x-coordinate = -3 - 4 = -7
Original y coordinate = 1
2 units up means y coordinate increases by 1
So new y-coordinate = 1 + 2 = 3
Translated point = (-7, 3)

Victoria drew a diagram of her laptop that she uses at school. It is in the shape of a rectangle. The dimensions are as follows:
Length: 13x - 9 units
Width: 4.5x + 8 units
Inequality is a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.. The inequality that represents the given situation is 13x - 9 > 4.5x + 8
What is Inequality?Inequality is a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
From the question, we are to determine the inequality that represents the given situation
From the given information, we have that
The length of the laptop is given by 13x - 9 units
and The width of the laptop is given by 4.5x + 8 units
If the length is greater than the width, then we can write that
13x -9 > 4.5x + 8
Hence, the inequality that represents the given situation is 13x - 9 > 4.5x + 8

Using multiple line and angle theorems, the values of each of the 14 angles are given.
Using the geometry theorems :
1.)
∠2 is a right angle = 90°
2.)
∠1 + ∠2 + ∠3 = 180° (sum of angle on a straight line)
90 + ∠1 + 54° = 180°
∠1 = (180 - 144) = 36°
(∠2 and ∠5) ; (∠3 and ∠6) ; (∠1 and ∠4) are vertically opposite ;
Hence,
∠4 = 36°
∠5 = 90°
∠6 = 54°
∠3 = ∠8 = 54° (corresponding angles)
∠9 + ∠8 = 180° (sum of angle on a straight line)
∠9 = (180 - 54) =126°
∠7 = ∠9 = 126° (vertically opposite angles)
∠8 = ∠10 = 54° (vertically opposite angles)
∠4 = ∠13 = 36° (corresponding angles )
∠12 + ∠13 = 180° (sum of angle on a straight line)
∠12 = (180 - 36) =126°
∠11 = ∠13 = 36° (vertically opposite angles)

The number of days for which the costs are the same is 6 days.
How to illustrate the information?Let the number of days be represented by d.
A rental car agency charges a flat fee of $131.00 plus $49.00 per day to rent a certain car. This will be
131 + 49d
Another agency charges a fee of $77.00 plus $58.00 per day to rent the same car. This will be
77 + 58d
Equate both equations
131 + 49d = 77 + 58d
Collect like terms
58d - 49d = 131 - 77
9d = 54
Divide
d = 54 / 9
d = 6 days.
Therefore, the number of days for which the costs are the same is 6 days.

There are 20 cubic feet of sand left over from a project. Mr. Wilson wants to build a sand box to hold the left-over sand. He built a rectangular box. The box is 5 feet long by 2 feet wide. How deep will the sand be once it is poured into the sandbox
The depth of the box once the sand is poured into it is 2 feet
Volume of a boxVolume of the sand left = 20 cubic feetLength of the box = 5 feetWidth of the box = 2 feetHeight of the box = x feetVolume of the box = length × height × width
20 = 5 × 2 × x
20 = 10x
divide both sides by 10x = 20/10

We are translating the point from (6,4) to (3,2) Look at the x values. We start at 6 and move to 3. That means that we moved 3 units to the left.
Now look at the y values. We start at 4 and move to 2. That means that we moved down 2 spaces.

Let f(x)=x-2 and g(x)=x²-3 x+2 . Perform each function operation and then find the domain. -2 g(x)+f(x)
The outcome of -2 g(x) + f(x) is 4 x -2 x ² and the domain is [ 0 , 2 ] .
Given,
f (x) = x - 2 and g (x) = x² - 3 x + 2
The question states to find the summation of the function f, that is, f (x) = x - 2, and function g, that is, g (x) = x² - 3 x + 2
Performing the addition operation on these functions is just like simple addition.
This means that when we add the two functions f (x) and g (x), we get
f (x) + g (x) = x - 2 + x² - 3 x + 2
=> f (x) + g (x) = x ² - 2 x
This implies that the summation or addition of the two functions f (x) and g (x) gives x ² - 2 x
needed result = -2 g(x) + f(x) = -2 ( x² - 2 x ) = -2 x ² + 4x = 4 x -2 x ²
To find domain,
y = 4 x -2 x²
=> 4x -2 x² ≥ 0
=> 2 x * ( 2 - x ) ≥ 0
=> 2 x ≥ 0 and 2 - x ≥ 0
=>x ≤ 2 and x ≥ 0
=> the final Domain = [ 0 , 2 ]
Therefore, we get the result of -2 g(x) + f(x) as 4x -2 x ² and the domain as [ 0 , 2 ] .

How to express the number as a percentage?The number is given as
6.961 x 10^27
To express the number given as 6.961 x 10^27 as a percentage, we simply multiply the number by 100%
So, we have:
6.961 x 10^27 = 6.961 x 10^27 * 100%
Express 100 as 10^2
So, we have:
6.961 x 10^27 = 6.961 x 10^27 * 10^2%
Apply the law of indices, when evaluating the product
