f'(c) = 20
Interval [1, b]
Step 2: Check/Identify
Function [1, b] is continuous.

A vertical parabola goes through (1,-2), (-3, 10), and (4, 31). Use matrices to
solve for D, E, and F, given the general form x² + y2 + Dc + Ey + F = 0 (since it
is a vertical parabola there is not a z term).

Answer:
D = 1/2 , E = -1/2 , F = -5/2
Step-by-step explanation:
vertical parabola : ( 1,-2), ( -3, 10 ), (4, 31 )
General form ; [tex]x^2 + y^2 + Dx + Ey + F = 0[/tex]
( 1 ,-2 ) = x1, y1
( -3, 10 ) = x2, y2
( 4, 31 ) = x3, y3
hence :
[tex]y1 = ax_{1} ^2 + bx_{1} + c[/tex]
[tex]y2 = ax_{2} ^2 + bx_{2} + c[/tex]
[tex]y3 = ax_{3} ^2 + bx_{3} + c[/tex]
attached below is the detailed solution required
D = 1/2 , E = -1/2 , F = -5/2

Then;
Using midpoint formula;
[tex](x,y) = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]
Put all values.
[tex](x,y) = ( \frac{0 + 10}{2} , \frac{9 + 5}{2} )[/tex]
Simplify it.
[tex](x,y) = (5,7)[/tex]
Therefore, the midpoint is (5,7)

Step-by-step explanation:
A baker sells bread for $4 a loaf and rolls for $1 each. The baker needs to sell $36 worth of baked goods by
the end of the day.
Enter a linear equation that describes the problem.
An equation for the value of the baked goods is
bread sold, and r is the number of rolls sold.
= $36, where b is the number of loaves of
Explanation:
Cost of 1 loaf of bread = $4
Cost of 1 roll = $1
The baker needs to sell both items and it should be worth $36.
To find the linear equation, Suppose, the baker sells "b" loaves of bread and "r" rolls.
Then the total cost of the sales has to be $36.
So, the linear equation will be:
4b + 1r = 36
Multiple choice: Which of the following angles, when drawn in
standard position, would not be coterminal with an angle that
measures 270°?
(1)-90°
(3) 630°
(2) 990°
(4) 720°
Answer:
Step-by-step explanation:
4
The angle that should be drawn in standard position, would not be coterminal with an angle that measures 270° should be 720 degrees.
What is coterminal?Coterminal angles refer to the angles in standard position where angles should be along with the initial side on the positive x-axis that have a common terminal side.
Therefore, The angle that should be drawn in standard position, would not be coterminal with an angle that measures 270° should be 720 degrees.

Which answer is correct? Please hurry
Answer:
15
Step-by-step explanation:
40 of them are offense players, 5 are special teams which means that 15 are defensive
Answer: 2/3 of 60 = 40
1/12 of 60 = 5
40 + 5 = 45 obviously.
45 + 15 = 60.
Therefore the amount of defensive players would be 15.
Lila rode her bike from 9:30 am to 11:10 am this morning. She rode 1.5 miles every 10 minutes. What is the total number of miles Lila rode this morning?
Answer:
15mi
Step-by-step explanation:
9:30am to 11:10am equals 100 minutes
100 minutes divided by 10 minutes per segment equals 10 segments
1.5 miles per segment multiplied by 10 segments equals 15 total miles
A sequence has an initial value (I) of -17 and its fourth term (a4) is 35. What is its general equation? Its 14th term?
Also, A sequence has a CR of 4/5 and its eighth term (a8) is (393216/3125). What is its general equation? Its 3rd term?
Answer:
The sequence is an Arthemtic ProgressionAn=A1+(n-1)d
A1 is first term, An is nth term, n is number of term, and d is common difference
therefore
A4=35, A1= -17
A4=A1+(4-1)d
35= -17+3d
35+17=3d
52=3d
52/3=3d/3
14=d
common diffrence(d)=14
The general solution is given byAn= -17+(n-1)14
An= -17+14n-14
An= -31+14n
An= 14n-31
A14 term, means n=14
From An=A1+(n-1)d
A14= -17+(14-1)14
= -17+(13×14)
= -17+182
= 165.
Therfore, the 14th term is 165.
2. A sequence has a CR of 4/5 and its eighth term (a8) is (393216/3125). What is its general equation? Its 3rd term?
solution
common ratio(r)=4/5
eighth term(G8)=393216/3125
From Gn= G1r^(n-1)
G8 means n=8
G8=G1r^(n-1)
393216/3125=G1(4/5)^(8-1)
393216/3125=G1(4/5)^7
G1=(393216/3125)/(4/5)^7
G1=600
The first term is given by G1=600
ThereforeThe General equation is given by
The General equation is given by Gn= 600(4/5)^(n-1)
3rd term (G3)
G3= G1(4/5)^(3-1) where n=3,
=600(4/5)^2
=600(16/25)
=384
Therefore, the 3rd term is given by G3= 384.

0, 3, and 6 are the correct answer.
The values of x that are solutions to the given inequality are 0, 3, and 6.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
7 + 4x > x - 2
Solve for x.
7 + 4x > x - 2
Subtract x on both sides.
7 + 4x - x > -2
7 + 3x > -2
Subtract 7 on both sides.
7 + 3x - 7 > -2 - 7
3x > -9
Divide both sides by 3.
x > -3
This means x is greater than -3.
i.e -2, -1, 0 , 1, 2, 3, 4, 5, . . . . .
From the given option we can select the correct answers.
We see that,
0, 3, and 6 are the correct answer.
