Bill will rent a car for the weekend. He can choose one of two plans. The first plan has no
initial fee but costs $0.70 per mile driven. The second plan has an initial fee of $50 and
costs an additional $0.50 per mile driven. How many miles would Bill need to drive for the
two plans to cost the same?
Clear
Undo Help
Answer:
250 miles
Step-by-step explanation:
Let number of mile driven be x
plan 1: Cost = 0.7x
plan 2: Cost = 50 + 0.5x
for both plans to cost the same,
Plan 1 Cost = Plan 2 Cost
0.7x = 50 + 0.5x (solve for x)
0.7x - 0.5x = 50
0.2x = 50
x = 250 miles

What is the area the major sector AOB?
Answer:
11.59 units²
Step-by-step explanation:
Step 1 : Determine radius
From reading the graph, looks like the radius is approx 3.2 units
Alternatively, calculate the radius:
the height of the triangle AOB = 1 unit, 1/2 base of triangle AOB = 3 units.
Using Pythagorean theorem, hypotenuse OB of a right angle triangle,
= √(1² + 3²) = √10 = 3.16 (pretty close to our estimate above)
Area of major sector,
= [tex]\frac{210}{360}[/tex] * area of full circle
= [tex]\frac{210}{360}[/tex] * 2πr
= [tex]\frac{210}{360}[/tex] * 2π (3.16)
= 11.59 units²

The measure of one of the small angles of a right triangle is 18 less than twice the measure of the other small angle. Find the measure of both angles. Use integers only
Answer:
36° and 54°
Step-by-step explanation:
We are given that one of the small angles of a right angled triangle is 18 less than twice the measure of the other small angle.
We are to find the measure of both angles.
Assuming [tex]x[/tex] to be the other small angle, 8 less than twice the measure of the other small angle = [tex]2x-18[/tex].
Summing all three angles up ti get:
[tex]x+(2x-18)+90=180[/tex]
[tex]3x=180-90+18[/tex]
[tex]3x=108[/tex]
[tex]x=\frac{108}{3}[/tex]
x = 36°
So other angle will be [tex]2(36)-18=[/tex] 54°.
Answer:
36° and 54°
Step-by-step explanation:
let x be one of the smaller angles, then the other smaller angle is 2x - 18 ( 18 less than twice the other )
Since it is a right triangle then the sum of the 2 smaller angles equals 90, so
x + 2x - 18 = 90
3x - 18 = 90 ( add 18 to both sides )
3x = 108 ( divide both sides by 3 )
x = 36
One angle = 36°
the other angle = (2 × 36) - 18 = 72 = 18 = 54°

Determine whether angle ABC should be solved by using the Law of Sines or the Law of Cosines. Then solve the triangle.
a = 10, b = 11, c = 14
Answer:
Law of Cosines
Angle A = 45°
Angle B = 51°
Angle C = 84°
Step-by-step explanation:
Law of sines is used when we are given
a) two angles and one side or
b) two sides and non-included angle
Law of cosines is used when we are given
a) three sides or
b) two sides and included angle
In the given question we are given three sides so, Law of Cosines will be used to solve the triangle.
Law of Cosines is:
[tex]a^2 = b^2 + c^2 -2bccos A\\b^2 = a^2 + c^2 -2accos B\\c^2 = a^2 + b^2 -2abcosC[/tex]
We will find the three angles A ,B and C of the triangle using above formula.
a= 10, b=11, c=14
Putting values and finding angle A
[tex]a^2 = b^2 + c^2 -2bccos A\\(10)^2 = (11)^2 + (14)^2 -2(11)(14)cosA\\100 = 121 + 196 -308cosA\\100 = 317 -308 cosA\\100-317 = -308cosA\\-217/-308 = cos A\\0.704 = cos A\\=> A = cos ^{-1}(0.704)\\A= 45[/tex]
Now finding angle B
[tex]b^2 = a^2 + c^2 -2ac cos B\\(11)^2 = (10)^2 + (14)^2 - 2(10)(14)cosB\\121 = 100+196 - 280cosB\\121 -296 = -280cosB\\-175/-280 = cosB\\0.625 = cosB\\=> B = cos^{-1} (0.625)\\B = 51[/tex]
Now finding angle C
[tex]c^2 = a^2 + b^2 -2abcosC\\(14)^2 =(10)^2 + (11)^2 -2(10)(11)cosC\\196 = 100+121 -220cosC\\196 -221 = -220cosC\\-25/-220 = cos C\\0.11 = cosC\\=> C = cos^{-1}(0.11)\\C= 84[/tex]
Answer:
Law of Cosines; A ≈ 45.2°, B ≈ 51.3°, C ≈ 83.5°

What graph represents an even function
If f(x) is a function and f(1) = 5, then which of the following could not be true?
Of(1) = 1
f(2)= 1
f(5) = 5
RE
-
NEXT QUESTION
O ASK FOR HELP
Answer:
f(1) = 1
Step-by-step explanation:
A function can have only one value of y for a given value of x.
Thus, if f(1) = 5, we cannot have f(1) = 1.
We can have f(2) =1 and f(5) = 5, because these are values of y for different values of x,
The first diagram below is the graph of a function, because there is only value of y that corresponds to a given value of x.
The second diagram is not the graph of a function, because there are two values of y that correspond to a given value of x.
However, the top semicircle and the bottom semicircle separately are graphs of functions, because they each have only value of y that corresponds to a given value of x.
Final answer:
The statement that could not be true for a function f(x) where f(1) = 5 is any claim that f(x) takes a different value than 5 for any x within the domain [0, 20], where f(x) is described as a horizontal line. Therefore, if f(1) = 5, it must be true that f(x) = 5 for all x in [0, 20].
Explanation:
If f(x) is a function and f(1) = 5, then it indicates that when we input 1 into the function f, we get the output of 5. The question asks which statements could not be true based on this piece of information and additional details regarding the nature of function f. The provided information suggests that the graph of f(x) is horizontal for 0 ≤ x ≤ 20, which means the output value of f(x) is the same for any input value x within that domain.
Likewise, we can determine some possible characteristics of f(x) based on the nature of continuous functions. Adding a constant to f does not affect the derivative, so despite the value of f at x = 1 being 5, we cannot deduce the exact form of f but can infer its behavior around that point. It is essential to note that when a function is defined as a continuous horizontal line within a certain domain, its value is constant across that domain. As a result, if f(1) = 5 for the function f(x) = a horizontal line on the interval [0, 20], it implies that f(x) must be 5 for all x in that interval.
Therefore, any statement that implies the function has a different value than 5 for any x in [0, 20] cannot be true. For instance, if there were a claim that f(2) ≠ 5 or that f(x) is not defined for some x within the interval where it is supposed to be a horizontal line, such a statement would be false given the function's described behavior.

the price of one share of XYZ inc's stock drop by $0.02 on Monday. On Tuesday the price goes back up by $0.05.
Write an expression with three terms to show the change in price of XYZ stock.
_____________________________________________________________
If one share of XYZ stock cost $34.18 at the start of business on Monday morning, what is the price of the one share of XYZ stock at the close of business on Tuesday evening?
Answer:
1. $(x+0.03) - $x
2. $ 34.21
Step-by-step explanation:
Let the price of XYZ inc's share to be = $ x
On Monday, the price drops by $ 0.02 = $ x- $ 0.02 = $ (x-0.02)
New price of shares on Monday is = $ (x- 0.02)
On Tuesday the price goes up by $0.05 = $ (x-0.02) + $ 0.05 = $(x-0.02+0.05)
New price on Tuesday = $( x+ 0.03)..............................................(a)
Change in price of one share of XYZ's stock= Price on Tuesday - price of share
= $(x+0.03) - $x..........................................(b)
2. Give that x= $34.18 solve equation (a) above
Price on Tuesday at close of business= $ (x+0.03)
= $ (34.18+0.03)
= $ 34.21

Which Property of equality accurately completes Reason B?
A). Addition Property of Equality
B). Divison Property of Equality
C). Substitution Property of Equality
D). Subtraction Property of Equality
Answer:
D Subtraction Property of Equality
Step-by-step explanation:
Whenever we subtract the same number of expression from both sides of the equation, the equality remains the same.
Reason A. - Consecutive Interior Angles
Reason B. - Substitution Property of Equality
Reason C. - Subtraction Property of Equality
The Property of equality that accurately completes Reason B in the figure and flowchart proof is the Addition Property of Equality (A).
Explanation:The property of equality that accurately completes Reason B in the figure and flowchart proof is the Addition Property of Equality (A).
The Addition Property of Equality states that if you add the same number to both sides of an equation, the equality is still preserved. In other words, if A + B = B + A, you can add the same number to both sides to obtain A + B + C = B + A + C, where C is any number.
In the given figure and flowchart proof, the equation A + B = B + A represents the Addition Property of Equality, and by applying this property, we can conclude that Reason B should be completed with the Addition Property of Equality (A).
Basketball court has a perimeter of 278 feet the basketball court is 38 feet longer than it is wide find the length and the width of the garden justify your answer
ANSWER
[tex]w = 50.5[/tex]
[tex]l = 88.5[/tex]
EXPLANATION
The basketball court has a rectangular shape.
The perimeter of this court is calculated using the formula
[tex]P=2(l + w)[/tex]
It is given that,the court has a perimeter of 278ft. Let the width of the court be 'w' units, then the length is "w+38"
The perimeter then becomes:
[tex]2(w + 38+ w) = 278[/tex]
[tex]2w + 38= 139[/tex]
[tex]2w = 139 - 38[/tex]
[tex]2w = 101[/tex]
[tex]w = 50.5[/tex]
[tex]l = 50.5 + 38 = 88.5[/tex]
Check
[tex]P = 2(88.5 + 50.5)[/tex]
[tex]P = 2(139) = 278[/tex]
Evaluate f(x)=-x^2+1 for x=-3
For this case we have a function of the form [tex]y = f (x)[/tex], where:
[tex]f (x) = - x ^ 2 + 1[/tex]
We must evaluate the function for [tex]x = -3[/tex]
Then we have to replace:
[tex]f (-3) = - (- 3) ^ 2 + 1\\f (-3) = - 9 + 1[/tex]
Different signs are subtracted and the sign of the major is placed:
[tex]f (-3) = - 8[/tex]
ANswer:
[tex]f (-3) = - 8[/tex]
2x+5-3x=8(x+1); solve for x.
We are given:
2x + 5 - 3x = 8(x + 1)
We can start with several things. First, we can combine the x terms on the left side of the equation, and apply the distributive property on the right side of the equation.
5 - x = 8x + 8
Now, we can add x to both sides, and subtract 8 from both sides to isolate the variable.
5 - x = 8x + 8
-8 + x + x -8
We end up with:
9x = -3
By dividing both sides by 9, we get x = [tex]-\frac{1}{3}[/tex].
If you want to check your answer, just plug x in!
2([tex]-\frac{1}{3}[/tex]) + 5 - 3([tex]-\frac{1}{3}[/tex]) = 8([tex]-\frac{1}{3}[/tex] + 1)
[tex]-\frac{2}{3}[/tex] + 5 + 1 = [tex]-\frac{8}{3}[/tex] + 8
[tex]-\frac{2}{3}[/tex] + [tex]\frac{18}{3}[/tex] = [tex]-\frac{8}{3}[/tex] + [tex]\frac{24}{3}[/tex]
[tex]\frac{16}{3}[/tex] = [tex]\frac{16}{3}[/tex]
As you can see, [tex]\frac{16}{3}[/tex] = [tex]\frac{16}{3}[/tex] as a result of having x = [tex]-\frac{1}{3}[/tex].
First you must distribute the 8 to the numbers inside the parentheses
2x + 5 - 3x = 8 (x + 1)
2x + 5 - 3x = 8*x + 1*8
2x + 5 - 3x = 8x + 8
Now you must combine like terms (let's first start with the like terms on the left side). This means the numbers with the same variables must be combined...
-3x + 2x = -x
so...
-x + 5 = 8x + 8
Now you must combine like terms by combining -x with 8x. To do this first add 1x to both sides (what you do on one side you must do to the other). Since x is negative on the left side, addition (the opposite of subtraction/negative) will cancel it out (make it zero) from the left side and bring it over to the right side.
-x + x + 5 = 8x + x + 8
0 + 5 = 9x + 8
5 = 9x + 8
Now bring 8 to the left side by subtracting 8 to both sides (what you do on one side you must do to the other). Since 8 is being added on the right side, subtraction (the opposite of addition) will cancel it out (make it zero) from the right side and bring it over to the left side.
5 - 8 = 9x + 8 - 8
-3 = 9x
Next divide 9 to both sides to finish isolating x. Since 9 is being multiplied by x, division (the opposite of multiplication) will cancel 9 out (in this case it will make 9 one) from the right side and bring it over to the left side.
-3/9 = 9x/9
x = [tex]\frac{-1}{3}[/tex]

If f(x) = 7 + 4x and g(x) = 2x, what is the value of 8 (5)?
A)11/2
B)27/10
C)160
D)270
If the functions f(x) = 7 + 4x and g(x) =1/2x then the value of (f/g)(5) is 270, option D is correct.
What is a function?A relation is a function if it has only One y-value for each x-value.
The given functions are f(x) = 7 + 4x and g(x) =1/2x
We have to find the value of (f/g)(5)
We know that from properties of functions
(f/g)(a)=f(a)/g(a)
So let us find f(5) and g(5)
f(5)=27
g(5)=1/10
(f/g)(5)=27/(1/10)
=27×10
=270
Hence, if the functions f(x) = 7 + 4x and g(x) =1/2x then the value of (f/g)(5) is 270, option D is correct.
