What is quadratic equation?Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power. The quadratic formula to solve a quadratic equation ax2 + bx + c = 0 is x = [-b ± √(b2 - 4ac)]/2a.
Given that:
By definition, the graph of Quadratic function is a parabola.
The Standard form of a Quadratic function is the following:
[tex]f(x)=ax^{2} +bx+c[/tex]
Where "a", "b" and "c" are real numbers (a≠0)
It is important to remember that if the value of the leading coefficient "a" is larger, then the parabola will be narrower.
So, given the following Quadratic equation:
[tex]y=-2x^{2} -1[/tex]
You can identify that:
IaI=2
Therefore, the equation that has a graph that crosses the y-axis at a point lower than the graph, must have a leading coefficient larger than 2.
[tex]y=-3x^{2} +1[/tex]
Where:
IaI=3
Notice that:
3>2

Please help me show my work for, Larry has a piece of wood that is 2.45 feet long and 2.097 inches wide. Part B: Using the width of the wood in Part A, what is the area, in square feet, of the piece of wood rounded to the nearest hundredth? Plsss hurry and help me
Answer: 0.43ft²
Step-by-step explanation:
You didn't really specify part A but In assuming that the question you posted is part A. Anyways in this case, area will be calculated by multiplying the length by the width.
Since the piece of wood has a length that is 2.45 feet and width that is 2.097 inches, then the area will be:
= 2.45 × 0.17475
= 0.4281375 ft²
= 0.43ft² to nearest hundredths
Note 1 foot = 12 inches
Therefore, 2.097 inches = 2.097/12 = 0.17475 feet

Step-by-step explanation:
The inequalities h > 42 and h < 60 represents the height requirements for an amusement park ride, where h represents the person's height in inches. Write a description that can be placed on a sign to clearly explain the rules as to who can ride the ride. You may wan to include some examples.
If h > 42 and h < 60, where h is in inches, then we can say 42 < h < 60.
This translates to "the person's height must be between 42 inches and 60 inches, excluding both endpoints".
So for example, if someone is h = 50 inches, then they can go on the ride. This is because 42 < 50 < 60 is true. I've simply replaced h with 50.
On the other hand, something like 42 < 70 < 60 is false, meaning that h = 70 isn't allowed as they are too tall.
The person cannot have a height of h = 42, and they can't have a height of h = 60 either since we're leaving the endpoints out.
As a final example, if the person is h = 40 inches, then they can't ride either because 42 < 40 < 60 is false. They are too short in this case.

a) If volume of a cylinder is 4817 and the radius is 4, find the height.
Answer:
71. 8
Step-by-step explanation:
volume of a cylinder = 4/ 3 π r² h
=> 4817 = 4/ 3 × 22/ 7 × 4² × h
=> h = (4817 × 3 × 7)/ (4 × 22 × 4²)
=> h = 71.8

Answer:
second option
Step-by-step explanation:
find angle c
angle a + angle c = 110 degree (sum of two interior opposite angle is equal to the exterior angle formed )
70 + angle c = 110
angle c = 110 - 70
angle c = 40 degree
find angle b
angle a + angle b + angle c = 180 degree (sum of interior angle of a triangle)
70 + angle b + 40 = 180
angle b + 110 = 180
angle b = 180 - 110
angle b = 70 degree
when two sides are equal the triangle can be named as isosceles triangle.
Answer:
option B
Step-by-step explanation:
∠ABD + ∠ABC = 180° [ straight line angle ]
110° + ∠ABC = 180°
∠ABC = 180 - 110 = 70°
option A : False
Option B : True,
Since two angles are same, the given triangle is isosceles.
option C : False
Nothing mentioned about the sides in the figure. Though it is isosceles
it does not mention anything about sides.
If two angles of a triangle are congruent,
then the sides opposite those angles are congruent.
That is , AC = BC
Option D : False, Because only B satisfies.

Arrange the polynomial equations in increasing order of the maximum number of extrema they could have. y = x6 − 6x3 + 5x y = x5 + 4x3 − 5x y = x3 + 21x2 + 110 y = 3x2 + 5 y = x4 − 17x2 + 72 ↓ ↓ ↓ ↓
The increasing order of maximum number of extrema they could have is;
y = 3x² + 5y = x³ + 21x + 2y = x⁴ − 17x² + 72y = x5 + 4x³ − 5xy = x6 − 6x3 + 5xWhat is the maximum number of extrema they could have in increasing order?The extrema of a polynomial is otherwise termed it's "turning point(s)". It follows that a polynomial with a degree n would have (n-1) number of turning points. It therefore follows on this basis that the arrangement of the polynomial equations in increasing order of possible extrema they could have is;
y = 3x² + 5
y = x³ + 21x + 2
y = x⁴ − 17x² + 72
y = x5 + 4x³ − 5x
y = x6 − 6x3 + 5x

Polygon DRMF is congruent to SLTO. Name two sets of congruent angles and two sets of congruent sides.
Answer:
✔️2 sets of corresponding angles
<D and <S
<R and <L
✔️2 sets of corresponding sides
DR and SL
RM and LT
Step-by-step explanation:
When two polygons are congruent, it implies that they have the same shape and size. Therefore, their corresponding angles and sides are congruent to each other.
When naming congruent polygons, the arrangement of the vertices are kept in a definite order of arrangement.
Therefore, Given that polygon DRMF is congruent to SLTO, the following angles and sides correspond to each other:
<D corresponds to <S
<R corresponds to <L
<M corresponds to <T
<F corresponds to <O
For the sides, we have:
DR corresponds to SL
RM corresponds to LT
MF corresponds to TO
FD corresponds to OS.
We can select any two out of these sets of corresponding angles and sides as our answer. Thus:
✔️2 sets of corresponding angles
<D and <S
<R and <L
✔️2 sets of corresponding sides
DR and SL

using top line....
5x-5y + 7x-15 = 180 (that is a line)
12x - 5y = 195
using bottom line
4x+ 4y +2x+ y = 180
6x + 5y =180
~~~~~~~~~~~~~~~~~~
12x - 5y = 195
6x + 5y =180
(fives cancel)
18x = 375
x = 20.83
y= 11
Answer:
x=125/6
y=11
Step-by-step explanation:
Same side interior angles have a sum of 180 if the transversal passes through a pair of parallel lines.
So we have the following two equations:
7x-15+5x-5y=180
4x+4y+2x+y=180
Let's simply(combine like terms):
12x-5y-15=180
6x+5y=180
Add 15 on both sides for first equation:
12x-5y=195
6x+5y=180
Equations are set up so we can use linear combination or elimination (adding equations together to eliminate y):
18x=375
Divide both sides by 18:
x=375/18
Simplify (reduce fraction):
x=375/18 ÷3/3=125/6
Now let's go back and find y using either equation:
6x+5y=180 with x=125/6
6(125/6)+5y=180
125+5y=180
5y=180-125
5y=55
y=11
x=125/6 and y=11
