What is a rectangle?A rectangle is a type of parallelogram that has equal diagonals.
All the interior angles of a rectangle are equal to the right angle.
The diagonals of a rectangle do not bisect each other.
The dimensions of the given rectangle is (650 - 2x) and x.
Then, the area of the given rectangle is A(x) = x(650 - 2x)
In order to find the maximum area enclosed take the derivative of A(x) and equate it to zero as follows,
(660 - 2x) - 2x = 0
=> 4x = 660
=> x = 660 / 4
=> x = 115
Now, the maximum area is the value of A(x) at x = 115 as below,
= 115 × (650 - 2×115)
= 115 × 320

We are given the initial function to be
[tex]\begin{gathered} A=A_0e^{-0.316t} \\ \text{where} \\ A_0=550mg \end{gathered}[/tex]Page 5
Question 4
We are told to use the function above to estimate how long it will take for the amount in the body to be 175mg.
This simply translates to making A= 175 in the equation so that we will obtain
[tex]175=550e^{-0.316t}[/tex]So we will make t the subject of the formula
To do so, we can follow the steps below
Step 1: Divide both sides by 550
[tex]\begin{gathered} \frac{175}{550}=\frac{550e^{-0.316t}}{550} \\ 0.318=e^{-0.316t} \end{gathered}[/tex]Next, we will take the natural logarithm to both sides
[tex]\begin{gathered} ln(0.318)=\ln (e^{-0.316t}) \\ \ln 0.318=-0.316t \\ -0.316t=\ln 0.318 \end{gathered}[/tex]Next, we will divide both sides by -0.316

Answer: 2(x-2)=6
Step-by-step explanation: when they say twice, so you make is times 2, then it said the difference of a number which would be a variable, or x, and 2, is 6, so one part is =6, next is the variable -2, so you can use x-2, then in order to multiply everything, you need to make parenthesis.

A line has an x-intercept of 8 and a y-intercept of 3. What is the equation of the line?
Answer
y = (-3/8)x + 3
Multiply through by 8
8y = -3x + 24
Explanation
The slope and y-intercept form of the equation of a straight line is given as
y = mx + b
where
y = y-coordinate of a point on the line.
m = slope of the line.
x = x-coordinate of the point on the line whose y-coordinate is y.
b = y-intercept of the line.
So, we just need to solve for the slope of this line.
For a straight line, the slope of the line can be obtained when the coordinates of two points on the line are known. If the coordinates are (x₁, y₁) and (x₂, y₂), the slope is given as
[tex]Slope=m=\frac{Change\text{ in y}}{Change\text{ in x}}=\frac{y_2-y_1}{x_2-x_1}[/tex]For this question, the x and y intercepts are given. Since these are points where the line crosses the x and y axis, we can write them in coordinates form as
x-intercept = (8, 0)
y-intercept = (0, 3)
(x₁, y₁) and (x₂, y₂) are (8, 0) and (0, 3)
[tex]\text{Slope = }\frac{3-0}{0-8}=\frac{3}{-8}=-\frac{3}{8}[/tex]y = mx + b
m = slope = -(3/8)
b = y-intercept = 3
y = mx + b
y = (-3/8)x + 3
Multiply through by 8
8y = -3x + 24

The rate of change at point A on the graph below for the y-axis in relation to the x-axis is -0.5.
What is the rate of change?The term "rate of change" (ROC) describes the rate at which something changes over time.
Thus, it is not the number of individual changes themselves but rather the acceleration or deceleration of changes (i.e., the rate).
The rate of change is a tool used in finance to comprehend price returns and spot trend momentum.
Other instances of changing rates are as follows: 40 more rats are added to the colony every week.
So, the rate of change is:
The point is given at 1.5 with respect to the y-axis.
And we can clearly see that it has been decreased to 1 with respect to the y-axis.
So, the rate of change:
1.0 - 1.5 - = -0.5
Therefore, the rate of change at point A on the graph below for the y-axis in relation to the x-axis is -0.5.

The average height of students at uh from an srs of 19 students gave a standard deviation of 3. 2 feet. Construct a 95% confidence interval for the standard deviation of the height of students at uh. Assume normality for the data.
The 95% confidence interval for the standard deviation of the height of students at UH is given by; CI = (1.81, 4.03)
How to find the confidence interval for standard deviation?
The formula for the confidence interval for the standard deviation is given by the formula;
CI = √[(n - 1)s²/(χ²ₙ ₋ ₁, α/2)], √[(n - 1)s²/(χ²ₙ ₋ ₁, (1 - α)/2)]
We are given;
Sample size; n = 19
D F = n - 1 = 19 - 1 = 18
Standard Deviation; s = 3.2
Confidence Level; CL = 95% = 0.95
Significance level; α = 1 - 0.95 = 0.05
Thus, using Chi-square distribution table online we have;
χ²₁₃, ₀.₀₂₅ = 24.736
(χ²₁₃, ₀.₉₇₅) = 5.01
Now, the 95% confidence interval for the standard deviation of the height of students at UH is given by :-

[tex]\begin{gathered} f(8)=80\cdot(1.25)^8 \\ =476.83 \\ \approx477 \end{gathered}[/tex]So in 8th month number of book denoted is 477.
How do I do this my teacher just assigned this and I don’t know what to do ?
We need to subtract both expressions, then simplify it and make only one expression:
First, subtract both expressions:
[tex](-3x+9y)-(8x-6y)[/tex]Then:
[tex]-3x+9y-8x+6y[/tex]Now, simplify like terms:
[tex]-11x+15y[/tex]Therefore, the result expression is -11x+15y.

The value of x for functions f(x)=(1+2x)/x and g(x)=2+x is 1 or -1
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given,
f(x)=(1+2x)/x
g(x)=2+x
f(x)=g(x)
Plug in values of f(x) and g(x)
(1+2x)/x=2+x
1+2x=x(2+x)
Apply distributive property on RHS
1+2x=2x+x²
1+2x-2x=x²
x²=1
x=±1
The value of x is 1 or -1.
