f(x)=(x-3)(x+8
a) x-intercepts are _________
b) midpoint of the x-intercepts is ___________
c) the extreme value is _______________
d) f(_) = ______________
Answers
Answer:
See belowStep-by-step explanation:
The x-intercepts are the points with y- coordinate of 0
(x - 3)(x + 8) = 0x - 3 = 0 or x + 8 = 0x = 3 or x = - 8a) x-intercepts are
3 and - 8b) midpoint of x-intercepts is
(3 - 8)/2 = - 5/2 = - 2.5c) The extheme value has x- coordinate of - 2.5 and y- coordinate
(-2.5 - 3)(- 2.5 + 8) = (-5.5)(5.5) = - 30.25d) f(- 2.5) = - 30.25
Answer:
[tex]\sf a) \quad x = -8 \:\:and \:\:x = 3[/tex]
[tex]\sf b) \quad \left(-\dfrac{5}{2},0\right)[/tex]
[tex]\sf c) \quad \left(-\dfrac{5}{2},-\dfrac{121}{4}\right)[/tex]
[tex]\sf d) \quad f(x)=\left(x+\dfrac{5}{2}\right)^2-\dfrac{121}{4}[/tex]
Step-by-step explanation:
Part (a)
The x-intercepts are the x-values when the curve crosses the x-axis, so when the function is equal to zero:
[tex]\implies f(x)=0[/tex]
[tex]\implies (x-3)(x+8)=0[/tex]
Therefore:
[tex](x-3)=0 \implies x=3[/tex]
[tex](x+8)=0 \implies x=-8[/tex]
Therefore, the x-intercepts are x = -8 and x = 3
Part (b)
[tex]\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\quad \textsf{where}\:(x_1,y_1)\:\textsf{and}\:(x_2,y_2)\:\textsf{are the endpoints}}\right)[/tex]
[tex]\sf \implies Midpoint=\left(\dfrac{-8+3}{2},\dfrac{0+0}{2}\right)=\left(-\dfrac{5}{2},0\right)[/tex]
Therefore, the midpoint of the x-intercepts is (-5/2, 0)
Part (c)
The extreme value is the vertex. The vertex is:
the minimum point if the parabola opens upwardsthe maximum point if the parabola open downwardsThe x-coordinate of the vertex is the x-value of the midpoint of the x-intercepts. Therefore, the x-value of the extreme value is x = -5/2.
To find the y-coordinate, substitute this into the given equation:
[tex]\implies \sf y=\left(-\dfrac{5}{2}-3\right)\left(-\dfrac{5}{2}+8\right)=-\dfrac{121}{4}[/tex]
Therefore, the extreme value is:
[tex]\sf \left(-\dfrac{5}{2},-\dfrac{121}{4}\right)[/tex]
Part (d)
The function in vertex form is:
[tex]\sf f(x)=\left(x+\dfrac{5}{2}\right)^2-\dfrac{121}{4}[/tex]
[tex]\begin{aligned}\implies \sf f\left(-\dfrac{5}{2}\right)& = \sf \left(-\dfrac{5}{2}+\dfrac{5}{2}\right)^2-\dfrac{121}{4}\\\\ & = \sf 0 -\dfrac{121}{4}\\\\ & = \sf -\dfrac{121}{4} \end{aligned}[/tex]

find the missing angles.
Answers
Answer:
1. 37 degrees, 2. 39 degrees, 3. 27 degrees
Step-by-step explanation:
You look at the total angle and subtract it by the angle that is given in the question since the two angles should add up to the whole angle of both. You should look at the number that is outside the angles and subtract it by the angle number inside then you will get the missing angles. The last one it is showing a 90 degree angle which is formed so you subtract 63 from 90.

Answers
The time it will take Jack and Chris to program the app when they work together is 4.24 hours.
What is a rate?Rate is a ratio that compares two different quantities which have different units.
Jack program an app in 9 hours. Therefore, the rate is as follows;
1 / 9
Chris can program the same app in 8 hours. Therefore, the rate is as follows;
1 / 8
When they do it together.
1 / 9 + 1 / 8 = 8 + 9/ 72 = 17 / 72
1 / t = 17 / 72
cross multiply
72 = 17 t
t = 72 / 17
t = 4.23529411765
t = 4.24

Yes (5,8) is included in solution region
Answer:
Given inequalities:
[tex]y < 4x-8[/tex]
[tex]y\geq -\dfrac{5}{2}x+5[/tex]
Part AThe graph of the system is made up of 2 straight line graphs.
The graph of [tex]y < 4x-8[/tex] is a dashed straight line with shading under the line.
The graph of [tex]y\geq -\dfrac{5}{2}x+5[/tex] is a solid straight line with shading above the line.
The solution area is the area where the shading of the two lines overlaps.
Part BTo determine if the point (5, -8) is included in the solution area, input the point into both inequalities:
[tex]\begin{aligned}y & < 4x-8\\\implies -8 & < 4(5)-8\\-8 & < 20-8\\-8 & < 12 \quad \leftarrow \textsf{correct}\end{aligned}[/tex]
[tex]\begin{aligned}y & \geq -\dfrac{5}{2}x+5\\\implies -8 & \geq -\dfrac{5}{2}(5)+5\\\implies -8 & \geq -7.5 \quad \leftarrow \textsf{incorrect}\end{aligned}[/tex]
Therefore, the point (5, -8) is not included in the solution area as it is only true for one inequality.

Using the triangle inequality theorem, the set of lengths that meet all the requirement is: 3, 4, 5, 7.
What is the Triangle Inequality Theorem?The triangle inequality theorem states that the sum of any of the two sides of a triangle must be equal or greater than the third side, i.e. if a, b, and c are sides of a triangle, then:
a + b ≥ cb + c ≥ aa + c ≥ bIf we have the following set of numbers, 3, 4, 5, 7.
Set 3, 4, 5 will give us:
3 + 4 ≥ 54 + 5 ≥ 33 + 4 ≥ 5This means 3, 4, 5 will form a triangle.
Set 4, 5, 7 will give us:
4 + 5 ≥ 75 + 7 ≥ 47 + 4 ≥ 5This means 4, 5, 7 will form a triangle.
Set, 3, 5, 7 will give us:
3 + 5 ≥ 75 + 7 ≥ 37 + 3 ≥ 5This means 3, 5, 7 will form a triangle.
Set 3, 4, 7 will give us:
3 + 4 ≥ 74 + 7 ≥ 37 + 3 ≥ 4This means 3, 4, 7 will form a triangle.
Therefore, we can conclude that the set of lengths, 3, 4, 5, 7, meets all the requirements.

One side of a square is 10 units. Which is greater, the number of square units for the area of the square or the number of units for the perimeter? Explain.
Answers
Given:
[tex]\text{Side of }\square \ \text{= 10 units}[/tex]
Area of square:
The area of the square can be determined by using the formula "(side)²".
⇒ Area of square = (side)²
⇒ = (10)² [Side = 10 units]
⇒ = (10)(10)
⇒ = 100 units²
Therefore, the area of the square is 100 units².
Perimeter of square:
The perimeter of the square can be found by using the formula "4(side)".
⇒ Perimeter of square = 4(side)
⇒ = 4(10)
⇒ = 4 × 10
⇒ = 40 units
Furthermore, the question says:
Which is greater?
- The number of square units (100) for the area of the square.
- The number of units (40) for the perimeter
Conclusion: Since 100 is greater than 40, the number of square units for the area of the square is greater than the number of units for the perimeter.

Given that;
The coordinate are,
⇒ A = (- 5x, 4y)
⇒ B = (- 2x, - 4y)
Now,
Since, We know that;
The distance between the points (x₁ , y₁) and (x₂, y₂) is,
⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²
So, The distance between the points (- 5x, 4y) and (- 2x, - 4y) is,
⇒ d = √ (- 2x - (- 5x))² + (- 4y - 4y)²
⇒ d = √(3x)² + (- 8y)²
Thus, The values needed to find the length AB is find as;
⇒ AB = √(3x)² + (- 8y)²

35% of the people support the home team at a baseball game.
As mentioned in the question,
3700 people attended a baseball game. 1295 of the people attending supported the home team, while 2405 supported the visiting team.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Total of people = 3700
People who support the home team = 1295
People who support the visiting team = 2405
Percentage of home support = 1295 / 3700 × 100

The perimeter of a rectangular garden is 264 m.
If the width of the garden is 56 m, what is its length?
Length of the garden:__m
Answers
We have the width and we have the perimeter
Plug those numbers in.
2L+2(56)=264
2(L)+112=264
Subtract 112 from both sides
2L=152
Divide by 2 on both sides
L=76
The length of the garden is 76 meters.
Step-by-step explanation:
Perimeter of garden = 264 m
width of the garden = 56 m
length of the garden = ?
Now..
Perimeter = 2 ( l + b )
264m = 2l + 112
264 - 112 = 2l
152 = 2l
l = 152 / 2
l = 76 m
Hence the length is 76m
