9) John and Sarah are each saving money for a car. The total amount of money John will
save is given by the function J = 28 + 4x.
The total amount Sarah will save is given
by the function S = x2 + 2x + 20. After
how many weeks, x, will they have the same amount of money saved? Explain how you arrived at your answer.
Answers
To find out how many weeks it will take for John and Sarah to save the same amount of money, we must set their respective functions equal to each other and solve for x.
J = S
28 + 4x = x2 + 2x + 20
x2 + 2x - 4x - 8 = 0
x2 - 2x - 8 = 0
(x - 4)(x + 2) = 0
x = 4 or x = -2
Since x must be a positive value, the answer is that it will take John and Sarah 4 weeks to have the same amount of money saved.
solve for the variable c in this equation: a(c + b) = d question 2 options: or c = d/a - b or c = d/a + b or c = b - d/a or c = d/b - a
Answers
Solving the equation a(c + b) = d for variable c, the variable c = (d/a) – b. (Option A)
Equation refers to a statement that represents an equality of values of two mathematical expressions and is indicated by the sign =.
In the given equation a(c + b) = d, in order to solve for the variable c, we must isolate the c variable at one side and collect other variables on the other side of the equation.
Given equation is:
a(c + b) = d
Divide both sides by a:
(1/a)*a(c + b) = d/a
c + b = d/a
Subtract b from both sides:
c + b – b = (d/a) - b

a satellite in a circular orbit 1250 kilometers above earth makes one complete revolution every 110 minutes. find its linear speed, round your answer to 2 decimal places. assume that earth is a sphere of radius 6400 kilometers.
Answers
Its linear speed would be 1637.75 miles/hour
Vt = 435,49 Km/min
Vt = 26129 Km/hour
Vt = 16630, 35 miles/hour
The distance from the earth center up to the satellite position is:
Earth radius + distance above the earth
radius of satellite 6400 + 1250 = 7650 Km
linear speed = Vt = 2π*r/T
where
r is the radius of the satellite and T period = 110 min
Then
Vt = 6,28* 7650 / 110
Vt = 4804/110
Vt = 43,674.54 Km/min
To get it in Km/h we must multiply by 60
Vt = 26204m/hour
And finally, to get it in miles per hour we divide it by 16
Vt = 1637.75 miles/hour

Which form of a linear equation do you prefer to use: slope-intercept form or point-slope form? list advantages and disadvantages of each. Compare your answer with a classmate's and discuss any differences.
Answers
Both slope-intercept form and point-slope form are equally important and useful, and easy to use. The advantages and disadvantages of both forms of linear equations are shown below.
Point-slope form:Advantages: One of the three forms we can use to express a straight line is the point-slope form, also referred to as the point-gradient form.
This form is helpful since it allows us to find the equation of the line by only knowing the slope and one point along the line.
Disadvantages: Since vertical lines have arbitrary slopes, one limitation of the point-slope form is that it cannot be used to describe the equation of a vertical line.
Standard form and slope-intercept form are two additional frequently used forms.
Slope-intercept:
Advantages: The slope of the line and the y-intercept are both clearly displayed in slope-intercept form.
The slope of the line and the single point the line passes through are both plainly displayed in point-slope form.
When working with equation systems, the standard form is more convenient. (specifically, to locate the intersection with matrices).
Disadvantages: Slope-intercept form has the same drawbacks as a point-slope form in that vertical lines cannot be represented since the slope of a vertical line is ill-defined.
Therefore, both slope-intercept form and point-slope form are equally important and useful, and easy to use. The advantages and disadvantages of both forms of linear equations are shown below.

The dimensions of the rectangular prism with the volume 33x cubic units are 11units, 9units, 4 units.
As given in the question,
Dimension of the rectangular prism in form of x are :
( x - 3 ) , ( x - 1 ) , and ( x - 8 )
Volume of the rectangular prism = 33x cubic units
⇒ ( x - 3 )( x - 1 )( x - 8 ) = 33x
⇒ ( x² -4x + 3 )( x - 8) = 33x
⇒ x³ -12x² + 35x -24 = 33x
⇒ x³ -12x² + 2x -24 = 0
⇒ x² ( x - 12 ) + 2 ( x - 12 ) = 0
⇒ ( x - 12 )( x² + 2 ) = 0
⇒ x = 12 or x = √ -2
Dimensions cannot be square root of negative.
⇒ x = 12
x - 3 = 9 units
x -1 = 11 units
x - 8 = 4 units
Therefore, the dimensions of the rectangular prism are 9 units, 11unitsm and 4 units.

Define the term variance?Variability is measured by the variance. The average of the squared variance is used to calculate it. The degree of dispersion within your data set is indicated by variance. The variance is greater in respect to the mean the more dispersed the data.Six red balls and four green balls are in an urn.
Till a urn is empty, we take balls out of it one at a time without replacing them and noting their order of the colors.
Let X represent the proportion of red balls in the initial five drawings.Y represent the proportion in the next five draws.The, the variance is found as-
Variance(X,Y) = E(XY) - E(X).E(Y).E(XY)
E(XY) = 25×(6/10)(4/9)
E(X) = 5×(6/10)
