Order the group of quadratic functions from widest to narrowest graph.
y= 6x2, y= -4.5x2, y= -x2
A. y= -4.5x2, y= -x2, y= 6x2
B. y= 6x2, y= -4.5x2, y= -x2
C. y= -x2, y= 6x2, y= -4.5x2
D. y= -x2, y= -4.5x2, y= 6x2
Answer:
B. y= 6x2, y= -4.5x2, y= -x2
Step-by-step explanation:
y = 6x2, y = −4.5x2, y = −x2
This should be correct )
To solve this problem you must keep on mind the following information: By definition, a quadratic function has the following form:
y=ax^{2}+bx+c
Where a is the leading coefficient.
If the leading coeficient is closer to zero, the parabola is widest,if it has a larger positive or negative value, the parabola is narrowest.
Therefore, by knowing the information above, you have that the answer is:
y=- x^{2} \\ y=-4.5 x^{2} \\ y=6 x^{2}
How many solutions exist for the given equation?
3(x-2)=22-x
O zero
Oone
Otwo
Oinfinitely many
Answer:
one solution
Step-by-step explanation:
3(x-2)=22-x
Distribute
3x -6 = 22-x
Add x to each side
3x-6+x = 22-x+x
4x-6 =22
Add 6 to each side
4x-6+6 = 22+6
4x = 28
Divide by 4
4x/4 = 28/4
x = 7
There is one solution
Answer:
It has only one solution
Step-by-step explanation:
[tex]3(x - 2) = 22 - x [/tex]
open the brackets:
[tex]3x - 6 = 22 - x[/tex]
collect like terms together:
[tex]3x + x = 22 + 6[/tex]
then solve:
[tex]4x = 28 \\ x = \frac{28}{4} \\ \\ x = 7[/tex]

The sum of first three terms of an arithmetic series is 21. If the sum of the first two terms is subtracted from the third term then it would be 9. find the three terms of the series. The first and last bra
Answer:
The terms are - 1, 7 and 15.
Step-by-step explanation:
Let the terms be a-d, a, a+d.
ATQ, a-d+a+a+d=21, a=7 and a+d-(a-d+a)=9. 2d-a=9, d=8. The terms are - 1, 7 and 15.
The first three terms will be : -1, 7, 15
We have sum of first three terms of an arithmetic series is 21. It is given that if the sum of the first two terms is subtracted from the third term then it would be 9.
We have to find the three terms of the series.
What is Arithmetic progression or sequence?An arithmetic progression or sequence with common difference [tex]d[/tex] is given as -
a, a + d, a + 2d, a + 3d .....
According to the question -
a + (a + d) + (a + 2d) = 21
3a + 3d = 21
3(a + d)=21
a + d = 7 (Eqn. 1)
(a + 2d) - (a + a + d) = 9
a + 2d - a - a - d = 9
d - a = 9
a = d - 9
Substituting the value of 'a' in Eqn. 1, we get -
d - 9 + d = 7
2d - 9 = 7
2d = 16
d = 8
Therefore -
a = 8 - 9
a = -1
The three terms are -
a = -1
a + d = -1 + 8 = 7
a + 2d = -1 + 2 x 8 = 15
Hence, the first three terms will be - -1, 7, 15

What are the geometric formulas???
Here are the options:
A.) y=1600(0.25)^x
B.) y=800(1/2)^x
C.) y=2/5(5)^x
D.) y=1/5(5)^x
E.) y=2000(1/2)^x
F.) y=1/3(3)^x
G.) y=2(2)^x
Please match the formulas with the correct sequence.
It’s a lot I know but I just absolutely suck at this stuff.
Answer:
1st sequence is F
2nd sequence is B
3rd sequence is G
4th sequence is A
5th sequence is D
6th sequence is E
7th sequence is C
Step-by-step explanation:
A) 1600*0.25= 400- the first term of the sequence
1600*0.25^2= 100- the second term
so it is 4th sequence
B) y=800* (1/2)^x
The first term is 800*1/2=400
The second term is 800*(1/2)^2= 800*1/4=200
the 2nd sequence
C) y= 2/5*5^x
The first term is y=0.4*5=2
The second term is y= 0.4*5^2=10
7th sequence
D) y=1/5* 5^x
The first term is y=1/5*5=1
The second term is y= 1/5 *5*5=5
The 5th sequence
E) y=2000*(1/2)^x
The first term of 2000*1/2=1000
The only sequence with such the first term is 6th sequence
F) y=1/3*3^x
y= 1/3*3=1 - the first term
y= 1/3*3*3=3
1st sequence
G) y= 2*2^x
y=2*2= 4 - the first term
it is the third sequence

The vertex of the parabola below is at the point (1, 5), and the point (2, 8) is on the parabola. What is the equation of the parabola? A. y = 2(x – 1)2 + 5 B. y = 3(x + 1)2 + 5 C. y = 3(x – 1)2 + 5 D. y = 2(x + 1)2 + 5
Answer: B
Step-by-step explanation:
the parabola having (1,5) as vertex have as equation:
y=k*(x-1)²+5
It is passing through (2,8)
8=k*(2-1)²+5 ==> k+5=8 ==> k=3
equation is y=3(x-1)²+5

The definition of parallel lines requires the undefined terms line and plane, while the definition of perpendicular lines requires the undefined terms of line and point. What characteristics of these geometric figures create the different requirements?
Answer:
Parallel lines never intersect, but they must be in the same plane. The definition does not require the undefined term point, but it does require plane. Because they intersect, perpendicular lines must be coplanar; consequently, plane is not required in the definition.
Step-by-step explanation:
Its correct trust me.
Answer:
Parallel lines never intersect, but they must be in the same plane. The definition does not require the undefined term point, but it does require plane. Because they intersect, perpendicular lines must be coplanar; consequently, plane is not required in the definition.

The measures of two angles of a triangle are 147º and 17º. Find the measure of the third angle.
Answer:
16 degrees
Step-by-step explanation:
147+17+x=180
164+x=180
subtract 164 from both sides
X = 16
Step-by-step explanation:
we know all measure of angles of triangle is 180⁰
so angle A + B + C = 180⁰
so 147⁰ + 17⁰ + C = 180⁰
so 164⁰ + C = 180⁰
so C = 180⁰- 164⁰
so C =16⁰
so third angle will be 16⁰

Jerry sold 320 tickets for the school play. He sold x adults tickets for $8 each and y child tickets for $5 each. He sold $1900 worth of tickets. Write a system of equations to model the situation.
What is the equation?
Answer:
x + y = 320
8x + 5y = 1900
Step-by-step explanation:
The equation x + y = 320 represents how 320 tickets were sold in total, from combining the adult and child tickets sold.
Since adult tickets are $8 each, the money from adult ticket sales can be represented by 8x.
The money from child ticket sales can be represented by 5y.
The equation 8x + 5y = 1900 represents how $1900 worth of tickets were sold.
So, the system of equations for the situation is:
x + y = 320
8x + 5y = 1900
Answer:
y = 220
x = 100
Step-by-step explanation:
x + y = 320
8x + 5y = 1900
x = 320 - y
8(320 - y) + 5y = 1900
2560 - 8y + 5y = 1900
2560 -3y = 1900
-2560 -2560
-------------------------
-3y = -660
----- -------
-3 -3
y = 220
x + 220 = 320
-220 -220
----------------------
x = 100

Cos A = 0.8090

Cot A = 1/ Tan(A) = 1/0.7265 = 1.3763
CSC A = 1/sin (A) = 1/0.5878 = 1.7013
SEC A = 1/ Cos(A) = 1/0.8090 = 1.236
jack wants to run at least 275 miles before the baseball season begins. he has already run 25 miles. he plans to run 2.5 miles each day. at this rate what is the fewest number of days he will need to reach his goal
Hey there! I'm happy to help!
We see that Jack has already run 25 miles.
25
He also wants to run 2.5 miles every day. This means we will multiply 2.5 miles by the number of days he runs. We will call the number of days x.
25+2.5x
And he needs this to equal 275.
25+2.5=275
We subtract 25 from both sides.
2.5x=250
We divide both sides by 2.5
x=100
So, Jack will need to run 100 days to meet his goal.
Have a wonderful day and keep on learning! :D
