Is (x + 4) a factor of f(x) = x3 - 2x2 + 5x + 1? Use either the remainder theorem or the factor theorem to explain your reasoning.
Answer:
no
Step-by-step explanation:
By the factor theorem
If (x + h) is a factor of f(x) then f(- h) = 0
Given (x + 4) with h = - 4 , then
f(- 4) = (- 4)³ - 2(- 4)² + 5(- 4) + 1
= - 64 - 2(16) - 20 + 1
= - 64 - 32 - 19
= - 115
Since f(- 4) ≠ 0 then (x + 4) is not a factor of f(x)

Answer:
75
Step-by-step explanation:
A = π r^2
A = Area of the circle which is in this question unknown
r = radius of the circle (which is the length of straight line from the center of the circle to any point on the circumference of the circle) and in this question is equal to 5 in
π = irrational number equal to 3.14159... but here you have told to use it as 3
A = π r^2
*plot the information we have get( r = 5 in and π = 3 ) in the equation above
A = (3)(5)^2
A = (3) (25)
A = 75 in^2

How does the figure verify the triangle inequality theorem?
Step-by-step explanation:
just think it through. it can only be the first option. the sides 7 and 4 are together 11, and they can only meet, when putting them flat on the 11 side. but yes, if you do that, they will meet, as 11 = 11.
the result would be an extreme triangle : appearing just as one, flat line (length 11), the angles being 180°, 0° and 0°.
The Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side. The correct option is A.
What is the triangle inequality theorem?The Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side.
Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,
(a+b) > c(b+c) > a(c+a) > bSides 7 and 4 are together 11, and they can only meet when they are flat on the side with a length of 11 units. However, if you do this, they will meet touch overlap on each other since 11 units = 11 units.
This will result in an extreme triangle which will more of look more like a straight line and will have angles of measure as 180°, 0°, and 0°.

The price of a train ticket from listen to cancel is normally do $146 however the Dre company is offering a special 55% of discount to children under the age of 16 what is the sale price of the ticket from Lexington to Kansas City
Answer:
80 or 80.3
Step-by-step explanation:
You have to find what is 55% of 146
first set up your fractions. [tex]\frac{n}{146}[/tex] =[tex]\frac{55}{100}[/tex]
for the fraction on the left the denominator is the whole amount (146) and n is the unknown number
For the fraction on the right, the numerator is where the percent goes (55) and the denominator is always 100
Next you multiply using the butterfly method
you multiply across. 146 x 55, which is 8030, and 100 x n, which is 100n,
Now divide 8030 by 100
All you have to do is move the decimal two places, since there are two zero's, and you get 80.3
When you round 80.3 you get 80

Which statement correctly compares the two functions?
А.They have the same x- and y-intercepts.
B.They have different x- and y-intercepts but the same end behavior as x approaches infinity.
C.They have the same y-intercept and the same end behavior as x approaches infinity.
D.They have the same x-intercept but different end behavior as x approaches infinity
Answer:
D. They have the same x-intercept but different end behavior as x approaches infinity
Step-by-step explanation:
A careful comparison reveals the g(x) values in the table are 1/2 the y-values in the graph. The x-intercepts are the same, but the y-intercepts and end behavior are different.

B is the midpoint of AC Find AB, BC and AC.
Step-by-step explanation:
Since B is the midpoint of AC. So,
AB = BC
12x - 12 = 4x + 28
12x - 4x = 28 + 12
8x = 40
x = 40/8
x = 5
Now,
AB = BC = 4(5) + 28
= 20 + 28
= 48 cm
Now
AC = AB + BC
AC = 48 + 48
AC = 96 cm

This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:

Subtract 18 from both sides of the equation :
5x = -18
Divide both sides of the equation by 5:
