Which of the following gives all values of b that satisfy the inequality above?

A) b<-1
B) b>-1
C) b<1
D) b>1

Answer:

7

Step-by-step explanation:

7 x 3 = 21

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.

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.

Answer:

  3) (1, 0)

Step-by-step explanation:

The midpoint can be computed as the average of the coordinates.

  M = (A + D)/2 = ((-2, 2) +(4, -2))/2 = ((-2+4)/2, (2-2)/2) = (1, 0)

The midpoint is (1, 0).

This is also easily seen on a graph of the points.

The green square is 15 ft wide by 15 ft tall.

The area of one green square is 15 x 15 = 225 square feet.

There are 4 sides plus the base : 225 x 5 = 1125 square feet for the green part.

One triangle has a base 15 feet wide and a height of 9 feet.

The area for one triangle is 1/2 x 15 x 9 = 67.5 square feet.

There are 4 triangles: 67.5 x 4 = 270 square feet.

Total: 1125 + 270 = 1,395 square feet.

Answer:

Part 1) [tex]y=-x^{2}[/tex]  ---> Translated up by 1 units

Part 2) [tex]y=x^{2}+1[/tex]  ---> Reflected across the x-axis

Part 3) [tex]y=-(x+1)^{2}-1[/tex]  ---> Translated left by 1 unit

Part 4) [tex]y=-(x-1)^{2}-1[/tex] ----> Translated right by 1 unit

Part 5) [tex]y=-x^{2}-1[/tex]  ----> Reflected across the y-axis

Part 6) [tex]y=-x^{2}-2[/tex]  ----> Translated down by 1 unit

Step-by-step explanation:

we know that

The parent function is

[tex]y=-x^{2}-1[/tex] ----> this is a vertical parabola open downward with vertex at (0,-1)

Calculate each case

Part 1) Translated up by 1 unit

The rule of the translation is

(x,y) -----> (x,y+1)

so

(0,-1) ----> (0,-1+1)

(0,1) ----> (0,0) ----> the new vertex

The new function is equal to

[tex]y=-x^{2}[/tex]

Part 2) Reflected across the x-axis

The rule of the reflection is

(x,y) -----> (x,-y)

so

(0,-1) ----> (0,1) ----> the new vertex

The new function is equal to

[tex]y=x^{2}+1[/tex]

Part 3) Translated left by 1 unit

The rule of the translation is

(x,y) -----> (x-1,y)

so

(0,-1) ----> (0-1,-1)

(0,1) ----> (-1,-1) ----> the new vertex

The new function is equal to

[tex]y=-(x+1)^{2}-1[/tex]

Part 4) Translated right by 1 unit

The rule of the translation is

(x,y) -----> (x+1,y)

so

(0,-1) ----> (0+1,-1)

(0,1) ----> (1,-1) ----> the new vertex

The new function is equal to

[tex]y=-(x-1)^{2}-1[/tex]

Part 5) Reflected across the y-axis

The rule of the reflection is

(x,y) -----> (-x,y)

so

(0,-1) ----> (0,-1) ----> the new vertex

The new function is equal to

[tex]y=-x^{2}-1[/tex]

Part 6) Translated down by 1 unit

The rule of the translation is

(x,y) -----> (x,y-1)

so

(0,-1) ----> (0,-1-1)

(0,1) ----> (0,-2) ----> the new vertex

The new function is equal to

[tex]y=-x^{2}-2[/tex]

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

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

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:

[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]

[tex]MaximumDistance=1200.1ft\\MinimumDistance=1199.9ft[/tex]

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]

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).

[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]b>a\wedge b\leq a^2[/tex], therefore [tex]pq<b\leq p^2q^2[/tex]

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)

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:

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].
