Answer:
The polynomial of the function degree '4'
x⁴ - x³ -46 x² -80x =0
Step-by-step explanation:
Explanation:-
Given zeros are 0 ,-5,8,-2
x =0 , x=-5 ,x=8 and x=-2
(x-0) , ( x+5) , (x-8) and (x+2)
The polynomial function with degree '4'
(x-0)(x-(-5)(x-8)(x-(-2) =0
x ( x+5) (x-8) (x+2) =0
(x² +5x)(x-8)(x+2) =0
(x³ -8 x²+5x² -40 x)(x+2) =0
( x³ -3 x² - 40 x) (x +2) =0
x⁴ + 2 x³ - 3 x³- 6 x²-40 x²- 80 x =0
x⁴ - x³ -46 x² -80x =0
Final answer:-
The polynomial of the function degree '4'
x⁴ - x³ -46 x² -80x =0

We want to find the zeros of this polynomial: p(x) = (x - 1)(x + 3) * (2x + 1) Plot all the zeros (-intercepts) of the polynomial in the interactive graph.
Answer:
Step-by-step explanation:
Because the function is a product, the zeros will occur when any term is equal to zero. For
(x-1)(x+3)(2x+1) the value will be zero when x=1,-3, or -1/2 so the points are
(-3,0), (-1/2,0), and (1,0)
The zeroes of the polynomials are, x=1,-3, or -1/2,Because the function is a product, zeros will appear whenever any term equals zero.
How do you determine a function's zeros and y-intercept?Zeros are the Intersection points of the curve of the considered function on the input axis.
y-intercept Points on the output axis where the curve of the considered function intersects.
On the x-axis, the value of the y-coordinate is 0. On the y-axis, the value of the x-coordinate is 0.
Thus, if the function is y=f(x), then placing y = 0 yields the function's zeros. Putting x = 0 produces the function's y-intercept.
Because the function is a product, the zeros will occur when any term is equal to zero.
(x-1)(x+3)(2x+1) =0
x=1,-3, or -1/2
The zeroes of the polynomials are, x=1,-3, or -1/2

Answer:
39 degrees
Step-by-step explanation:
Vertical angles are opposite angles made by two intersecting lines, this means they share a vertex. Vertical angles are always congruent. Congruent angles have the same measurements, so the other angle must be 39 degrees.

Step-by-step explanation:
Reduce 120/96 ( turn into a decimal)
Do the same for the others.
You should get 1.25, and the one doesn't get that as a decimal doesn't represent the plot on a scale drawing.

Answer:
4/3
Step-by-step explanation:
The slope equals the rise/run
Start at the first point on the graph. Then count how many times you went up till you are parallel with the second point. That will be the rise, which in this case is 4.
Then from your new point count how many times you went right, and that will be your run. In this case it is 3.
Put the rise an top, and the run on bottom, and you get the slope 4/3!

the sum of three number is 202, the second is three more than the first number, the third number is three times the second number. what are the three numbers ?
Answer:
x = 38
y = 41
z = 123
Step-by-step explanation:
x + y + z = =202
y = x + 3
z = 3y = 3(x + 3) = 3x + 9
x + y + z = x + x + 3 + 3x + 9 = 5x + 12 = 202
5x + 12 = 202
5x = 190
x = 38
y = x + 3 = 41
z = 3y = 123

Calculate the area of this triangle.
17 cm
8 cm
15 cm-
Area - Triangles
Overview
Answer:
There are 3 possible answers because you didn't state which value was base or height.
Going off the assumption that the base is 15 cm and the height is 8 cm, the area is 60 cm. (same answer if base is 8 cm and height is 15 cm)
A = 1/2(b*h)
A = 1/2(15*8)
A = 1/2(120)
A = 60
Going off the assumption that the base is 17 cm and the height is 8 cm, the area is 68 cm. (same answer if base is 8 cm and height is 17 cm)
A = 1/2(b*h)
A = 1/2(17*8)
A = 1/2(136)
A = 68
Going off the assumption that the base is 15 cm and the height is 17 cm, the area is 127.5 cm. (same answer if base is 17 cm and the height is 15 cm)
A = 1/2(b*h)
A = 1/2(15*17)
A = 1/2(255)
A = 127.5
Solver 12g<48, Show steps in how to get answer
Answer:
G must be less than four
Step-by-step explanation:
12 (4) = 48 Therfore, any value less than 4 will make the inequality correct
For example, 12 (3.9999999) = 47.9999988 < 48
Therfore, any rational number less than positive 4 will serve as a possible value for g

Three angles of a quadrilateral are in the ratio 3 : 5 : 8. The mean of these
angles is 80°. Find all the four angles of the quadrilateral.
Answer:
See answers below
Step-by-step explanation:
Given the ratio of three angles as 3:5:8
Total ratio = 3+5+8 = 16
Mean = x+y+z/3
80 = x+y+z/3
x+y+z= 240
To get x;
x =3/16 * 240
x = 45degrees
To get y;
y = 5/16 * 240
y = 5 * 30
y = 75degrees
To get z;
z = 8/16 * 240
z = 120 degrees
Fourth angle = 360 - (120+75+45)
Fourth angle = 360-240
Fourth angle - 120 degrees
