Can someone tell me how to evaluate quadratic equations easily with steps (40 points)
here's an example ;^;
f(x) = 3(x + 6)2 - 75
Answer:
See below
Step-by-step explanation:
Expansion
[tex]f(x)=3(x+6)^2-75\\\\f(x)=3(x+6)(x+6)-75\\\\f(x)=3(x^2+12x+36)-75\\\\f(x)=3x^2+36x+108-75\\\\f(x)=3x^2+36x+33[/tex] <-- Stop here if this is what you need
Factorization
[tex]f(x)=3(x^2+12x+11)\\\\f(x)=3(x+1)(x+11)[/tex]
We know from vertex form that the vertex of the parabola is [tex](-6,-75)[/tex] and when factored, the zeroes are [tex]x=-1[/tex] and [tex]x=-11[/tex].

how do I make frequency table
Answer:
To make such a frequency distribution table, first, write the class intervals in one column. Next, tally the numbers in each category based on the number of times it appears. Finally, write the frequency in the final column. A frequency distribution table drawn above is called a grouped frequency distribution table.

If f(x) = 3x+ 2 and g(x) = 2x-2, what is (f-8)(x)?
Answer: x + 4
Step-by-step explanation:
If it is asking us for (f - g)x, then we will subtract the function g from function f. Why? The x distributes creating f(x) - g(x), so we use this to solve.
Given:
g(x) = 2x - 2
f(x) = 3x + 2
Set up:
f(x) - g(x)
(3x + 2) - (2x - 2)
Distribute the negatie:
3x + 2 - 2x + 2
Reorder to combine like terms:
3x - 2x + 2 + 2
Combine like terms:
x + 4
(f - g)(x) = x + 4
A and B are independent events. If P(A) = 0.50 and P(A and B) = 0.20, find P(B).
The independent events are illustrations of probability, and the value of P(B) is 0.40
How to determine the value of P(B)?The given parameters are:
P(A) = 0.50
P(A and B) = 0.20
Two events A and B are independent, if
P(A and B) = P(A) * P(B)
So, we have:
0.50 * P(B) = 0.20
Divide both sides by 0.50
P(B) = 0.40
Hence, the value of P(B) is 0.40

The discriminant of the function is 120, and the function has 2 different x-intercepts
How to determine the discriminant?
The function is given as:
f(x) = -7x^2 + 8x + 2
The discriminant (d) is calculated using:
D =b^2 - 4ac
So, we have:
D = 8^2 - 4 * (-7) * 2
Evaluate
D = 120
Because the value of D is greater than 0, then the function has 2 different x-intercepts

Change in KE if mass is doubled
KE (original) = 1/2mv²KE (new) = 1/2 x (2m) x v²KE (new) = mv²⇒ KE is doubledChange in KE if speed is doubled
KE (new) = 1/2 x m x (2v)²KE (new) = 1/2 x 4 x mv²KE (new) = 2mv²⇒ KE is quadrupledNot only would I like the value of x, but also I wonder how I’d go about solving this problem?
Answer:
x = 58
Step-by-step explanation:
This question can be solved by using the exterior angle property, which states that the exterior angle of a triangle = the sum of the two opposite interior angles.
62 lies on a line, so the exterior angle is 180 - 62, or 118 degrees.
Using the EAP, we can conclude the following:
(x + 2) + (x) = 118
2x + 2 = 118
2x = 116
x = 58
Hope this helps
Answer:
X=58
Step-by-step explanation:
1.) 62+2+2x=180
2) 64+2x=180 (add 62 and 2)
3) 2x=116 (subtract 64 from 180)
4)x=58 (divide 116 by 2 =58

By the angle sum property of a triangle, the value of x would be equal to 9.
What is the angle sum property?The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.
The sum of the triangle of angles is 180.
6x + 56 + 38 + t = 180
t = 180 - 94 - 6x
t = 86 - 6x
By linear pair
10x + 58 + t = 180
10x + 58 + 86 - 6x = 180
4x + 144 = 180
4x = 180 - 144
4x = 36
x = 9

Select the correct answer. A company offers its employees free recreational activities and gym memberships. Of the 200 employees, 95 employees registered for recreational activities, 80 employees registered for gym memberships, and 30 employees did not register at all. If an employee is chosen at random, what is the probability that the employee has registered for both recreational activities AND gym memberships?
Answer:
1/40

Melody need 155 bags of 140 cu. inches to fill the vegetable garden.
What is Volume of Cuboid?The volume of the cuboid is the measure of the space occupied within a cuboid. The cuboid is a three-dimensional shape that has length, breadth, and height.
Here, Length of vegetable garden = 48 inch
breadth of garden = 30 inches
height of garden = 15 inches
Volume of garden = Length X width X height
= 48 X 30 X 15
= 21600 cu. inches
Volume of each bag = 140 cu. inches
Number of Bags required = Volume of garden/Volume of each bag
= 21600 / 140
≈ 155
Thus, Melody need 155 bags of 140 cu. inches to fill the vegetable garden.

B.3.no identifier is given
4.Arc DBC is the difference between a full circle (360°) and short arc DC. The measure of short arc DC is marked as 96°, so ...
arc DBC = 360° -96° = 264°
5.Αrc BC is twice the measure of the inscribed angle BDC it subtends.
arc BC = 2×60° = 120°
6.Arc AB is the difference between 360° and the sum of arcs AD, DC, and CB.
arc AB = 360° -(90° +96° +120°) = 54°
7.Angle ACD is half the measure of arc AD.
Angle ACD = 90°/2 = 45°
8.Angle ADC is half the measure of arc AC, which is the sum of arcs AB and BC
angle ADC = (54° +120°)/2 = 87°
9.Angle ACB is half the measure of arc AB
angle ACB = 54°/2 = 27°
