Let the child bicycle wheel radius be x
Then its circumference is
C = 2πxa) Solving for x
37.7 = 2*3.14xx = 37.7/6.28x = 6.0 inb) Mountain bicycle has twice the circumference of a child bicycle
In 2 seconds it makes 3 revolutions
It makes the distance of
d = 3*2*37.7 = 226.2 inches in t = 2 secondsSpeed = d/t
Speed is:
226.2/2 = 113 inches/second

What are the features of the quadratic function f(x) = x^2 + 10x + 21?
A) Vertex = (-5,-4), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of
symmetry is x = -5
B)
Vertex = (5,4), y-intercept = (0,-21), x-intercepts = (-7,0) and (-3,0), axis of
symmetry is x = 5
C)
Vertex = (-4,-5), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of
symmetry is x = -4
D)
Vertex = (-5,-4), y-intercept = (21,0), x-intercepts = (3,0) and (7,0), axis of
symmetry is x= -5
The features of the quadratic function f(x) = x^2 + 10x + 21 are Vertex = (-5,-4), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of symmetry is x = -5 so option (A) will be correct.
What is a quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.
For example 3x² + 6x + 8 = 0 here x has highest term as 2 and coefficient of x² is not zero.
The standard form of a quadratic equation is ax² + bx + c
The x vertex is given -b/2a
So,
x-vertex = -10/2 = -5
So y = (-5)² + 10(-5) + 21 = -4
So vertex is (-5, -4)
The Y-intercept is given as (0,y)
So,
y = 21
Therefore
y-intercept = (0,21)
the x-intercept is given as (x,0)
So,
x = -7 , -3
Therefore
x-intercepts = (-7,0) and (-3,0)
The Axis of symmetry is given by -b/2a
So,
⇒ -10/2 = -5
Hence "Vertex = (-5,-4), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of symmetry is x = -5".

Find the value of y.
(12x + 9)
(8x + 11)º
(14y + 7)o
Answer:
y = 7
Step-by-step explanation:
First, find the value of x.
[tex] (12x + 9) + (8x + 11) = 180 [/tex] (linear pair)
Solve for x
[tex] 12x + 9 + 8x + 11 = 180 [/tex]
Collect like terms
[tex] 12x + 8x + 9 + 11 = 180 [/tex]
[tex] 20x + 20 = 180 [/tex]
Subtract 20 from both sides
[tex] 20x + 20 - 20 = 180 - 20 [/tex]
[tex] 20x = 160 [/tex]
Divide both sides by 20
[tex] \frac{20x}{20} = \frac{160}{20} [/tex]
[tex] x = 8 [/tex]
Thus,
[tex] (12x + 9) = (14y + 7) [/tex] (vertical angles)
Plug in the value of x, and solve for y
[tex] 12(8) + 9 = 14y + 7 [/tex]
[tex] 96 + 9 = 14y + 7 [/tex]
[tex] 105 = 14y + 7 [/tex]
Subtract 7 from each side
[tex] 105 - 7 = 14y + 7 - 7 [/tex]
[tex] 98 = 14y [/tex]
Divide both sides by 14
[tex] \frac{98}{14} = \frac{14y}{14} [/tex]
[tex] 7 = y [/tex]

if 5x-7=13, what is the value of 10x-14
Answer:
10x-14=26
Step-by-step explanation:
x = 4
10 x 4 = 40
40 - 14 = 26
Answer:
26
Step-by-step explanation:
In order to answer this question, we must first find what x equals, so we need to solve for x in the equation 5x - 7 = 13:
5x - 7 = 13
+7 +7
5x = 20
/5 /5
x = 4
Now, we plug in 4 for 'x' in the equation 10x - 14:
10(4) - 14 =
40 - 14 =
26
So, 10(4) - 14 = 26

Step-by-step explanation:
Sultan measures the distance he drives to work each day using the odometer on his car, which measures distance in
miles, accurate to the nearest tenth of a mile. If the odometer reads 11.7 miles, what between what two quantities can
you be certain that the exact distance lies?
in two or more complete gfsentences, explain your reasoning,
Answer:
We can be sure that the actual distance lies between 11.65 and 11.74
Step-by-step explanation:
Here. we are told that the odometer measures to the nearest tenth.
The nearest tenth means to the nearest first digit after the decimal point
So the range of values we shall be writing will be the range that includes the smallest number that can be approximated to 11.7 and the largest number that can be approximated;
Thus, we have;
11.65 to 11.74
The reasoning is because the smallest number that can be approximated to 11.70 is 11.65 while the largest that can be approximated to 11.70 is 11.74. So the actual distance we need from the odometer is between 11.65 and 11.74

Answer:
y = -x -1
Step-by-step explanation:
The x- and y-coordinates will be the same for the parallel line, so we only need to find the constant that needs to replace the +8 in the given equation.
y = mx +b
y = -x +b . . . . . with the coefficient of x filled in
-4 = -(3) +b . . . with the given point filled in
b = -1 . . . . .add 3 to both sides

given the regular polygon, select all of the rotations and reflections that carry the figure onto itself.
Answer:
A. A rotation of 72º around the center, point D.
C. A reflection across line b through one vertex, the center d.
E. A reflection across line c, and the midpoint of the opposite side
Step-by-step explanation:
From Euclidean Geometry we get that sum of internal angles inside a polygon equals 360º and there is the following relationship in regular polygons:
[tex]\theta = \frac{360^{\circ}}{n}[/tex] (Eq. 1)
Where:
[tex]\theta[/tex] - Internal angle, measured in sexagesimal degrees.
[tex]n[/tex] - Number of sides, measured in centimeters.
If we know that [tex]n = 5[/tex], then internal angle of regular pentagon is:
[tex]\theta = \frac{360^{\circ}}{5}[/tex]
[tex]\theta = 72^{\circ}[/tex]
In consequence, rotating the regular pentagon 72º around the pentagon carries the figure onto itself due to angular symmetry. (Correct answer: A)
By adding any line passing the center of the regular pentagon (i.e. line cc', line bb'), which is collinear to any vertex and any point of the figure, we guarantee conditions of length symmetry so that reflection carries the figure onto itself. (Correct answers: C, E)

(16.5+1.5n)°(12+2n)°
Answer:
1.7n +28.5
Step-by-step explanation:
you compare like terms first
1.5n add it to 2n
it will equal to 1.7
then add 16.5 to 12
it will equal to 28.5
Your new equation will be
1.7n+ 28.5 if it was equal to something let's say it was equal to 180 as an example:
your equation will be
1.7n + 28.5= 180
-28.5= -28.5
1.7n= 151.5 you would divide it
it would equal 89.1 and change.
