The number of infected people will reach 568 in approximately 4 weeks
Linear equation and functionExponential equations are inverse of logarithmic equation and are represented by the equation below:
y = ab^x
where
a is the base value and x is the exponent
Given the equation that shows the number of infected people from an outbreak of the measles as:
y = 4(6)^t
If the number of infected people reach 568, hence;
568 = 4(6)^t
568/4 = 4(6)^t/4
6^t = 568/4
6^t = 142
Take the natural logarithm of both sides
ln(6^t) = ln142
t = ln142/ln6
t = 4.37
Hence the number of infected people will reach 568 in approximately 4 weeks

Step-by-step explanation:
The average amount of money spent by students in the cafeteria last week was $2.75. The actual amount spent varied by no more than $0.50. Write and solve an absolute value inequality to represent the range of possible amounts.
The average amount of money spent by students in the cafeteria last week was between $2.25 to $3.25
What is an equation?An equation is used to show the relationship between numbers and variables. An equation can be linear, quadratic depending on the degree.
Let x represent the average amount of money spent by students.
The absolute value inequality is given by the equation:
|x - 2.75| = 0.5
Hence:
x - 2.75 = 0.5 or -(x - 2.75) = 0.5
x = 3.25 or x = 2.25
The average amount of money spent by students in the cafeteria last week was between $2.25 to $3.25

The meaning of the 0.4m in this equation is the additional cost of hiring the delivery truck for m number of miles.
EquationGiven equation:
C = 0.4m + 68
Where
m = number of miles
C = total cost of hiring the delivery truck
68 = Fixed cost of hiring the delivery truck
0.48 = Additional cost per mile of hiring the delivery truck
For instance,
If the truck is hired for 10 miles
C = 0.4m + 68
= 0.4(10) + 68

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
The given function is: h(x) = -(x + 2)² +8.
This function is in the form: a[tex](x-h)^{2}[/tex]+k
Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror-like reflection of either side of the object. The word symmetry implies balance.
The axis of symmetry is given by x = h
By comparison, we have -h=2.
This implies h=-2
Therefore the axis of symmetry is x = -2
The maximum value of a function is the place where a function reaches its highest point, or vertex, on a graph. If your quadratic equation has a negative term, it will also have a maximum value.

2. Let f(x) = x4 + 2x3 - x² - 2x + 10. Given that one root of f(x) is 1 + i find all other roots.
All the roots of equation x⁴ +2x³ -x² -2x +10 are: (1 + i), (1 - i), -2i, 2i
In the given question, we have to find out all the roots or solutions for the equation x⁴ +2x³ -x² -2x +10. One of the roots given for this equation is 1+i
According to the 'Complex Conjugate' pairs, if an equation has a complex number as a root then its conjugate will also be a root of the equation.
So, we get z = 1 + i as a root then z* = 1 - i which is the conjugate of z, and z* will also be a root of the equation.
Also, the product of two roots will also be a root of the equation. So,
we know that, x = 1 + i, x = 1 - i, we get their product:
(x -(1 + i))*(x - (1 - i)) => by solving we get => x² -2x +2 = 0
=> x² -2x +1 = 1 => x² -x -x +1 = 1 (by middle term split)
=> x(x-1) -1(x-1) = 1 => we get (x - 1) as a factor
So, (x - 1) = 1 => x = 2
=> x = -2i, we get x = -2i
Again, by Complex conjugate pairs if x = -2i is a factor then it's conjugate x = 2i is also a factor.
Hence, the roots of the equation are: (1 + i), (1 - i), -2i, 2i

What is the equation of the line that passes through the point (-8,-8)(−8,−8) and has a slope of 0?
Answer:
[tex]y=-8[/tex]
Step-by-step explanation:
Recall the slope formula:
[tex]m=\frac{x_{2} -x_{1}}{y_{2} -y_{1}}[/tex]
Since all of the x and y values are -8, we can easily plug in the values.
[tex]m=\frac{-8+8}{-8+8}=0[/tex]
(The second -8 on the top and bottom is positive because adding when subtracting negatives, you must add. For example -1-(-1) would become -1+1=0)
Recall the point-slope formula:
[tex]y-y_{1} = m(x-x_{1} )[/tex]
Now substitute and solve.
[tex]y-(-8)=0(x-(-8)[/tex] Substitute
[tex]y+8=0(x+8)[/tex] Simplify
[tex]y+8=0[/tex] Distributive Property
[tex]y=-8[/tex] Subtraction Property
Therefore the answer is [tex]y=-8[/tex].

(b) What would the perimeter of this
rectangle be if the width was 10 feet?
(c) The perimeter of the rectangle is 78 feet. Set up an equation using w that models this
situation. Solve it and state the values for both the width and the length of the rectangle.
Part a: Expression for length; l = 2w + 3.
Part b: Perimeter equation; P = 2(l + 10).
Part c: Length of rectangle = 29 feet.
What is defined as the rectangle?A rectangle is a the kind of quadrilateral, a two-dimensional shape with four sides as well as four vertices. The rectangle's four angles are all right angles as well as equal to 90 degrees.The given conditions are-
Let 'l' be the length of the rectangle.
Let 'w' be the width of the rectangle.
Part a: expression for the length of a rectangle in the terms of w.
Length is three feet more than twice its width.
l = 2w + 3
Thus, the expression of l in terms of w is: l = 2w + 3.
Part b: Perimeter equation.
The width is given as 10 feet.
The formulae of perimeter if rectangle is;
P = 2(l + w)
Put the value;
P = 2(l + w)
P = 2(l + 10)
Thus, the equation for perimeter is P = 2(l + 10)
Part c: Length of rectangle.
perimeter of rectangle = 78 units.
P = 2(l + w)
w = 10 feet.
78 = 2(l + 10)
l + 10 = 39
l = 29
Thus, the length of the rectangle is found as 29 feet.

How to Create a Linear Equation for a Table?To create an equation in slope-intercept form, y = mx + b, for a table of values, use two pairs of values from the table to find the slope (m) and determine the y-intercept (b).
Using (5, 16.25) and (8, 26.00) find the slope (m):
Slope (m) = change in y / change in x = (26.00 - 16.25) / (8 - 5)
Slope (m) = (9.75) / (3)
Slope (m) = 3.25
Find the y-intercept (b) by substituting m = 3.25 and (8, 26.00) into y = mx + b:
26.00 = 3.25(8) + b
26.00 = 26.00 + b
26.00 - 26.00 = b
0 = b
b = 0
Substitute m = 3.25 and b = 0 into y = mx + b:
y = 3.25x + 0
y = 3.25x
Therefore, the equation that represents the cost, y, of x gallons of gasoline, is expressed as: y = 3.25x.

Find the y-intercept of the line on the graph
Since no equation of the line, or graph is provided in the question statement, considering the line to be [3x +4y = 12], the y-intercept of the line is 3.
As per question statement, we are supposed to determine the y-intercept of the line on the graph, but no equation of the line, or graph is provided. Hence, we considered the equation of a random line, say,
[3x +4y = 12] and then, determine it's y-intercept.
To solve this question, we can use two methods:
One method is by converting the given equation into the format of the standard equation of a line, and then comparing it to the standard equation to determine the y-intercept, i.e.,
The standard equation of line is (y = mx + c), where, "m" is the slope of the line, and "c" is the y-intercept. Converting [3x +4y = 12] to the form of the standard equation, we get,
[tex]3x+4y=12\\or,4y=-3x+12\\or,y=\frac{-3x+12}{4}\\ or,[y=(\frac{-3}{4})x+3]...(i)[/tex]
Now comparing (i) to the standard equation of line, we can identify that
(c = 3), i.e., y-intercept of the line [3x +4y = 12] is 3.
Another way we can determine the y-intercept of a line is by, substituting (x = 0) and then solving the equation for "y".
Y-Intercept: The y-intercept is the point on a cartesian plane, where a graph crosses the y-axis, i.e., the value of y when (x = 0).To learn more about Y-Intercepts, click on the link below.
