Need some help, please. What do I plot? I attempted to figure the questions out many times, but I've come to no clear conclusion, whoops.
Answer:
vertex is (4,-4) and another point is (6,0) or you could use (2,0) or many other options :)
Step-by-step explanation:
The cool thing about this question your quadratic is in factored form so your x-intercepts are easy to figure out, they are 2 and 6.
So you can plot (6,0) and (2,0).
The vertex will lie half between x=2 and x=6... so it lays at (6+2)/2=4
We just have to find the y-coordinate for when x=4.
Plug in 4 gives you (4-2)(4-6)=(2)(-2)=-4.
So the vertex is at (4,-4).
Solve for x: √x-13=2 The solution is
Answer:
x=225
Step-by-step explanation:
\sqrt{x} + (-13 + 13) = 2 + 13
\sqrt{x} = 15
√x-13=2
x=225
If you meant to write...
[tex]\sqrt{x - 13} = 2[/tex]
Then the following is the answer:
To solve this you must get rid of the square root. The opposite of square root is square. You must square both sides since what you do to one side you must do to the other...
([tex]\sqrt{x-13} )^{2}[/tex] = [tex]2^{2}[/tex]
x - 13 = 4
Finish completely isolating x. To do this first add 13 to both sides (what you do on one side you must do to the other). Since 13 is being subtracted, addition (the opposite of subtraction) will cancel it out (make it zero) from the left side and bring it over to the right side.
x + (-13 + 13) = 4 + 13
x + 0 = 17
x = 17
If you meant to write...
[tex]\sqrt{x}[/tex] - 13 = 2
Then the following is the answer:
To isolate [tex]\sqrt{x}[/tex]. To do this first add 13 to both sides (what you do on one side you must do to the other). Since 13 is being subtracted, addition (the opposite of subtraction) will cancel it out (make it zero) from the left side and bring it over to the right side.
[tex]\sqrt{x}[/tex] + (-13 + 13) = 2 + 13
[tex]\sqrt{x}[/tex] = 15
To completely isolate x you must get rid of the square root. The opposite of square root is square. You must square both sides since what you do to one side you must do to the other...
[tex](\sqrt{x})^{2} = 15^{2}[/tex]
x = 225

Suppose a company produces report indicates that the surveyed distance between two points is 1200 feet with a margin of error of ±0.1 feet. What are the maximum and minimum distances that the reader could assume based on the surveyed distance and margin of error?
The answers are:
[tex]MaximumDistance=1200.1ft\\MinimumDistance=1199.9ft[/tex]
Why?Since we are given the margin of error and it's equal to ±0.1 feet, and we know the surveyed distance, we can calculate the maximum and minimum distance. We must remember that margin of errors usually involves and maximum and minimum margin of a measure, and it means that the real measure will not be greater or less than the values located at the margins.
We know that the surveyed distance is 1200 feet with a margin of error of ±0.1 feet, so, we can calculate the maximum and minimum distances that the reader could assume in the following way:
[tex]MaximumDistance=ActualDistance+0.1feet\\\\MaximumDistance=1200feet+0.1feet=1200.1feet[/tex]
[tex]MinimumDistance=ActualDistance-0.1feet\\\\MaximumDistance=1200feet-0.1feet=1199.9feet[/tex]

The length of a parking Lot is 5 yards more than the width. If the area of the parking lot is 66 square yards, find the dimensions of the parking lot.
Answer:
6 yards by 11 yards
Step-by-step explanation:
Factors of 66 are ...
66 = 1·66 = 2·33 = 3·22 = 6·11
The last pair of factors differ by 5, so represent the solution to the problem.
The width of the parking lot is 6 yards; the length is 11 yards.
Final answer:
The parking lot's dimensions are found by setting a quadratic equation w × (w + 5) = 66 based on its area. Solving for w, the width is 6 yards, hence the length is 11 yards, making the dimensions 6 yards by 11 yards.
Explanation:
To find the dimensions of the parking lot when the length is 5 yards more than the width and the area is 66 square yards, we can set up an equation based on the area of a rectangle (area = length × width). We can define the width as w and the length as w + 5 since the length is 5 yards more than the width.
The equation representing the area will then be:
w × (w + 5) = 66
Solving this quadratic equation (w^2 + 5w - 66 = 0) by factoring or using the quadratic formula, we find that w = 6 or w = -11. We discard the negative value since a width cannot be negative, so the width is 6 yards and the length is 11 yards (since it's 5 yards more than the width).
Therefore, the dimensions of the parking lot are 6 yards by 11 yards.

Three friends share a pizza Sam ate 0.25 of the pizza mark ate 0.3 of the pizza and Jill ate 0.35 of the pizza can you write the amount each child ate as a fraction? What fraction of the pizza is left?
Step-by-step explanation :
Sam : 0.25 = [tex]\frac{25}{100}[/tex] = [tex]\frac{1}{4}[/tex] (Answer)
Mark : 0.30 = [tex]\frac{30}{100}[/tex] = [tex]\frac{3}{10}[/tex] (Answer)
Jill : 0.35 = [tex]\frac{35}{100}[/tex] = [tex]\frac{7}{20}[/tex] (Answer)
Total amount of pizza eaten = 0.25 + 0.30 + 0.35 = 0.9
Amount of pizza left = 1.0 - 0.9 = 0.1 = [tex]\frac{10}{100}[/tex] = [tex]\frac{1}{10}[/tex] (Answer)
consider the line y=7x-3 fine the equation that pass through -5,6 of a perpendicular
Answer:
[tex]y=-\frac{1}{7}x+\frac{37}{7}[/tex]
Step-by-step explanation:
Your equation is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. Your line has a slope of 7. In order to find the line perpendicular to this line, we have to take the opposite reciprocal of the slope. The perpendicular slope to m = 7 is m = -1/7. Now we go through x = -5 and y = 6 to find the new equation.
6 = -1/7(-5) + b gives us
6 = 5/7 + b and
b = 37/7
Therefore, the equation of the line perpendicular to your original line is
[tex]y = -\frac{1}{7}x + \frac{37}{7}[/tex]
Suppose that G(X) = F(x+ 9). Which statement best compares the graph of
G(x) with the graph of f(x)?
Answer: Option D
Step-by-step explanation:
By definition if we have a function F (x) and perform a transformation of the form
[tex]G (x) = F (x + c)[/tex]
Then it is true that:
If c is negative the graph of G(x) will be equal to the graph of F(x) displaced horizontally c units to the right
If c is positive, the graph of G(x) will be equal to the graph of F(x) displaced horizontally c units to the left.
Note that in this case the transformation is:
[tex]G (x) = F (x + 9)[/tex]
Then [tex]c = 9[/tex] and [tex]c> 0[/tex]
Therefore the graph of G(x) will be equal to the graph of F(x) displaced horizontally 9 units to the left
The answer is the option D.
ANSWER
D. The graph of G(x) is the graph of F(x) shifted 9 units to the left.
EXPLANATION
The given functions are F(x) and G(x).
The function, G(x) is obtain by translating or shifting the graph of F(x).
This translation is of the form.
[tex]G(x) = F(x+ 9)[/tex]
The '+9' within the parenthesis tells us that the shift is 9 units to the left.
Remember that for horizontal shift:
+ means a shift to the left.
The correct answer is D.

[tex]\dfrac{a^2}{b}[/tex] is an integer, where [tex]a,b\in\mathbb{Z_+}[/tex], therefore [tex]b|a^2[/tex] and [tex]b\leq a^2[/tex]
[tex]a=pq[/tex] therefore [tex]a^2=p^2q^2[/tex]
[tex]b>a\wedge b\leq a^2[/tex], therefore [tex]pq<b\leq p^2q^2[/tex]
So,

Area of a triangle = height x base ÷ 2
When ever you have an isosceles triangle, remember that you can split it in half to form two right angled triangles - which allow you to use Pythagoras' Theorem.
So we split 10cm in half to get 5cm.
We can then use 13cm and 5cm to work out the height:
Height = √(13² - 5²) (Note: you subtract because you are using the
= √144 (hypotenuse)
= 12
---------------------------------------------------------
Now to get the area, we just multiply the base (which is 10) by the height (which is 12) and divide by 2:
Area = 12 x 10 ÷ 2
= 6 x 10 (note: 12 ÷ 2 = 6 )
= 60 cm²

Answer:
x = 3.1 ft
Step-by-step explanation:
Use Pythagoras' Theorem to find the base of the triangle. The base of the triangle is half of 'x'. Let's call the base 'y' for now.
To find 'y' we must use this formula,
[tex]y^{2} = c^{2} -b^{2}[/tex]
'c' is the hypotenuse, the longer side, and 'b' is the other short side.
Sub in the numbers for 'c' and 'b',
[tex]y^{2} = 2.1^{2} -1.4^{2}[/tex]
= 2.45
Square root both sides to get 'y' by itself,
y = 1.5652.....
Remember that 'y' is half of x? Simply multiply 'y' by 2 to get an answer for 'x',
x = 1.5652.... x 2
= 3.1 ft (1 d.p. nearest tenth)

ms.wolf earns a salary of $50,000 per year plus a 4% commission on her sales. the average price of a share she sells is $50.
write an inequality to describe how many shares ms. wolf must sell to make an annual income of at least $70,000.
Answer:
[tex]2x + 50,000 \ge 70,000[/tex].
[tex]x \ge 10,000[/tex].
Step-by-step explanation:
What's the total income of Ms. Wolf in a year?
The annual income of Ms. Wolf comes in two parts:
The fixed salary of $50,000, andThe 4% commission on shares she sold.How many commission does Ms. Wolf receive for each share she sold? [tex]\$\;50 \times 4\% = \$\;50 \times 0.04 = \$\;2[/tex].
Let the number of shares that Ms. Wolf sold be [tex]x[/tex]. Ms. Wolf will receive a commission of [tex]\$\;2x[/tex].
Total annual income of Ms. Wolf: [tex]\$\; (50,000 + 2x)[/tex].
The phrase "at least" indicates that [tex]\$\; (50,000 + 2x)[/tex] shall be greater than or equal to $70,000. That is:
[tex]\$\; (50,000 + 2x)\ge \$\;70,000[/tex].
[tex]2x + 50,000 \ge 70,000[/tex].

add 5/9 and 5/6, then subtract 2/3 from the sum. please show work
Answer:
13/18
Step-by-step explanation:
We need to get a common denominator for 9,6,3
That would be 18
5/9 *2/2 = 10/18
5/6 * 3/3 = 15/18
2/3 *6/6 = 12/18
5/9+5/6 = 10/18 +15/18 = 25/18
Then
25/18 - 2/3 = 25/18 - 12/18 = 13/18
