Answer:
Step-by-step explanation:
The given function is
\(f(x)=(x-1)(x+7)\)
Zeroes of the function are
\((x-1)(x+7)=0\)
\(x=-7,1\)
It means, f(x) intersect x-axis at x=-7 and x=1.
Mid value of -7 and 1 is the x-coordinate of the vertex.
\(\dfrac{-7+1}{2}=-3\)
At x=-3,
\(f(-3)=(-3-1)(-3+7)=(-4)(4)=-16\)
So, the vertex of the function is at (-3,-16).
The given function can be written as
\(f(x)=x^2+7x-x-7\)
\(f(x)=x^2+6x-7\)
Here leading coefficient is negative, it means it is an upward parabola.
So, we conclude that
1. The graph is increasing on the interval x > -3.
2. The graph is decreasing on the interval x < -3.
3. The graph is positive only on the intervals where x <-7 and where x > 1.
4. The graph is negative only on the intervals where -7 < x < 1.
Therefore, the correct options are 2, 3 and 4.

Perimeter: 380ft
Answer:
The perimeter is 380 ft^2.
Step-by-step explanation:
To find the perimeter of a rectangle, you have to use the 2(a+b) formula as a method of solving. This formula can also be written as a+b+a+b or 2a+2b.
To solve it, you input a as 51 and 139 as b, though this doesn't really matter all too much. Using the previously stated formula, you should get 2(51+139). Solving what's in the parenthesis first (51+139), you should get 190.
Now, you should have the answer 2(190). Finishing off the equation and multiplying 2 by 190, your answer will be 380 ft^2.

A triangle with an area of 360 square meters was created from a triangle with an area of 2.5 square meters using a scale factor. What is the scale factor?
A 900:1
B 72:1
C 30:1
D 12:1
Answers
Answer:
The ratio of the areas of two similar figures is equal to the square of their scale factor. In this case, the original triangle has an area of 2.5 square meters, and the new triangle has an area of 360 square meters. Let x be the scale factor between the two triangles. Then we have:
(x^2)(2.5) = 360
Solving for x, we get:
x^2 = 360/2.5
x^2 = 144
x = sqrt(144)
x = 12
Therefore, the scale factor between the two triangles is 12:1, so the answer is D) 12:1.
The scale factor is 12:1.
The correct option is D.
What is Scale factor?A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is used to find the missing length, area, or volume of an enlarged or reduced figure as well as to draw the enlarged or reduced shape of any given figure. It should be remembered that the scale factor only affects how big a figure is, not how it looks.
We have,
Area of big triangle = 360 square meters
Area of Small triangle = 2.5 squared meters
let x be the scale factor between the two triangles.
So, x² (2.5)= 360
x² = 360/ 2.5
x²= 144
x= 12
Thus, the scale factor is 12:1.

In the diagram below, line AB is parallel to line CD. The measure of
∠∠ABC is 28° and the measure of ∠∠EDC is 42°. Find the measure of∠∠CED. Explain why you are correct by presenting an informal argument that uses the angle sum of a triangle.
what is the measure of ∠∠CED is ? And Explain why ?
Answers
Answer:
ced is 110 degrees
Step-by-step explanation:
because ECD is 28 degrees and 28+42=70 and a triange always = 180 degrees so it would have to be 110
The measure of ∠CED is 110 degrees by angle sum property of the triangle.
We are given that line AB is parallel to line CD.
The measure of ∠ABC is 28° and the measure of ∠EDC is 42°
What are exterior angles?An exterior angle is a measure of rotation between one extended side(we extend it virtually) of the polygon with its adjacent side which is not extended.
We know that line AB is parallel to line CD.
So according to alternate interior angles measure of ∠ABC is 28° will be equal to BCD.
Thus, Angle BCD= 28 degrees
Hence, in a triangle CED
∠CED + ∠EDC + BCD = 180
∠CED + 28 + 42 = 180
∠CED = 180 - 70
∠CED = 110 degrees
Therefore, the measure of ∠CED is 110 degrees by angle sum property of the triangle.

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
Answers
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Put the arrow on -1.3.
Step-by-step explanation:
In order to find -1.3, we first have to solve the problem.
-2 - (-0.7)
Since negative - negative = negative, we know our answer is already going to be negative.
Subtract -0.7 from -2, and to make it easier you can do it on a calculator if you want.
First remove the brackets, then turn the negative sign on -0.7 and the minus sign into a plus sign. It will turn into:
-2 + 0.7
When you add, 0.7 to -2, the sum is -1.3.
Therefore you mark the arrow on -1.3

B = -1 -> as x + B = 0 -> x = -B = -1.
When x = 0, y = -2, hence the value of A is obtained as follows:
A/-1 = -2
A = 2.
Then the division is given as follows:

Answers
Answer:

Step-by-step explanation:
If 20% of the workers is equal to 30 workers than in order to find 100% of the worker you need to multiply the percentage with a number that makes it 100% and then multiply that number to the 30 workers so
20% * 5 = 100%
30 * 5 = 150
