Answer:
According to the integral root theorem the only possible real, integral zeros are +/- factors of (10*3 - 8)
... or factors of 992(+/-). you can test by direct substitution. No positive values are roots ... try 1, 1332, but as x increases so does y ... so there are no positive roots.
Roots, means y = 0 ... so (x + 10)^3 = 8 ... take cube root ... x + 10 = 2 .. x = -8
x = -8 is a root
Testing other negatives and the y values are not zero but tend toward - infinity.
So the only real zero is x = -8
Answer:
it helps you
Step-by-step explanation:
this is for y = (x-10)^3 - 8
According to the integral root theorem the only possible real, integral zeros are +/- factors of (10*3 - 8)
... or factors of 992(+/-). you can test by direct substitution. No positive values are roots ... try 1, 1332, but as x increases so does y ... so there are no positive roots.
Roots, means y = 0 ... so (x + 10)^3 = 8 ... take cube root ... x + 10 = 2 .. x = -8
x = -8 is a root
Testing other negatives and the y values are not zero but tend toward - infinity.
So the only real zero is x = -8
Similarly for y = (x + 7)^3 +2 = 0
(x + 7)^3 = -2
x + 7 = cube root (-2)
x = -7 + cube root (-2) <<< the only real root
Is this a proportional relationship?
A student stands at the entrance of her school and notes the colors of cars that enter the parking lot. The results are shown in the bar graph below.
which of the following is a true statement regarding the info in the bar graph?
a. car color is a discrete variable
b. car color is a catagorial variable
c. car color is a continuous variable
d. frequency is a discrete variable
thank ya so much and have a lovely day!!
Answer:
B
Step-by-step explanation:
Color of car is a categorical variable. its value are not numerical
The frequency of cars entering the parking lot is a discrete variable so option (d) will be correct.
What is a variable?A variable in mathematics is a representation of any quantity whose value is changeable.
For example speed of a vehicle is a variable.
The value of the variable changes but the meaning of the variable never for example speed of vehicle changes but the word speed does not change.
A discrete variable is a variable whose values are different.
Since car color is not a variable because the meaning of variable is not constant in car color.
The frequency of vars is a discrete variable because it is different for each kind of car.
Hence "The frequency of cars entering the parking lot is a discrete variable".

Answer:
∠A = 115°
∠B = 65°
∠C = 115°
∠D = 65°
Step-by-step explanation:
The figure given is of parallelogram.
We need to find measure of each interior angle.
We are given:
∠A = (2x-15)°
∠B = x°
∠C = (2x-15)°
∠D = x°
We need to find measure of ∠A , ∠B, ∠C, ∠D
We know that sum of all angles of parallelogram = 360°
So, we can write: ∠A +∠B+ ∠C+ ∠D = 360°
Now putting their values and finding value of x first:
[tex]2x-15+x+2x-15+x=360\\Combining\:like\:terms:\\2x+x+2x+x-15-15=360\\6x-30=360\\6x=360+30\\6x=390\\x=\frac{390}{6}\\x=65[/tex]
So, we get x= 65
Now finding measure of each angle:
∠A = (2x-15)° = 2(65)-15 = 130-15 = 115°
∠B = x° = 65°
∠C = (2x-15)° = 2(65)-15 = 130-15 = 115°
∠D = x°= 65°
Answer is:
∠A = 115°
∠B = 65°
∠C = 115°
∠D = 65°
If the sum of the measures of the interior
angles of a polygon is 1930°, how many sides
does it have?
Answer:
Thus, the number of sides: n ≈ 13 (rounded to the nearest whole number).
Step-by-step explanation:
We know that the formula of the sum of the measures of the interior angles of a polygon
Sum = (n-2) × 180°
where
n is the number of sides
In your case, since the sum of the interior angles is 1930°, then
1930° = (n-2) × 180°
so we can determine the number of sides n, such as
1930 / 180 = n-2
[1930 / 180] + 2 = n
n ≈ 12.7
If 12.7 rounded to the nearest whole number, then
n ≈ 13
Thus, the number of sides: n ≈ 13 (rounded to the nearest whole number).

A group of friends wants to go to the amusement park. They have $94.25 to
spend on parking and admission. Parking is $14.75, and tickets cost $13.25
per person, including tax. Write and solve an equation which can be used to
determine p, the number of people who can go to the amusement park.
Answer:
1) The equation to determine the the number of people who can go to the amusement park is 14.75 + 13.25·p = 94.25
2) The number of people who can go to the amusement park is people
Step-by-step explanation:
The given parameters are;
The amount the group of friends have to spend on parking and admission = $94.25
The cost parking = $14.75
The cost of tickets per person = $13.25
The variable we let to represent the number of people who can go to the amusement park be "p"
1) The equation that can be used to determine "p" is therefore, given as follows;
14.75 + 13.25·p = 94.25
2) Therefore, we have, by making "p" the subject of the above equation;
p = (94.25 - 14.75)/13.25 = 6
Therefore, the number of people who can go to the amusement park, p = 6 people.
Answer:
Answer: 6
Step-by-step explanation:
Equation: 13.25p+14.75=94.25

For (triangle)DEF, you are required to construct the median DG to EF. Which of the following must be performed first?
A. Draw EF to DG.
B. Draw DG to EF.
C. Bisect DE at G.
D. Bisect EF at G.
Answer: C. Bisect DE at G.
Step-by-step explanation:
In a triangle, a median is a line segment drawn from a vertex to the midpoint of the opposite side of the vertex.So, for triangle DEF , if we draw the median DG to the opposite side EF.
Here EF is the opposite side to vertex D.
So, G must be the midpoint of line segment EF.
So , we need to first mark G on EF.
i.e. we need to bisect EF at G.
So first step would be : Bisect EF at G.

A cone has a diameter labeled twelve centimeters and a height labeled thirty-two centimeters. Find the area of a vertical cross section through the center of the base of the cone.
Answer:
[tex]A=0.0192[/tex]
Step-by-step explanation:
Diameter labeled twelve centimetres D =12cm => 0.12
height labeled thirty-two centimetres H= 32cm => 0.32
Generally the vertical cross section of this cone is a triangle
Mathematically solving
Area of vertical cross section through the center of the base of the cone is given by [tex]A=1/2 D*height[/tex]
[tex]A=R*H[/tex]
Therefore
[tex]A=\frac{0.12}{2} *0.32[/tex]
[tex]A=0.06 *0.32[/tex]
[tex]A=0.0192[/tex]

prove the circle centered at A la congruent to the circle centered at C.
Answer:
Huh!
The circles with of same radii or same circumference or same area are congruent.
No need to proof!
Step-by-step explanation:
Or just type it,
'Since they have the same radii, they are congruent!'
The two given circles are congruent as their radius are similar.
What is a circle?All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the center.So, the two circles are congruent because:
We know that:
AB = CDAnd AB and CD are the two radius of the given two circles.Since their radius is similar.So, the two circles will be congruent.
Therefore, the two given circles are congruent as their radius are similar.
