Using synthetic division, what is the factored form of this polynomial?
x^4+ 6x^3 + 33x^2 + 150x + 200
Answer:
(x + 2) (x +4) (x^2 + 25)
Step-by-step explanation:
Just did this problem
( + 2 ) ( ^3 + 4 ^2 + 2 5 + 1 0 0 )
( + 2 ) ( + 4 ) ( ^2 + 2 5 )
A factor is a number that completely divides another number. The factored form of the polynomial is (x² + 25 )(x + 2 )(x + 4 ).
What are factors?A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product because the product is divisible by them.

What is the slope of a line perpendicular to the line y=2x+5 ?What is the slope of a line perpendicular to the line y=2x+5 ?
1/2
−2
2
−1/2
Answer:
[tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
Hi there!
In the given equation [tex]y=2x+5[/tex], the slope of the line is 2.
Perpendicular lines always have slopes that are negative reciprocals, like negative "flipped" fractions.
Example: The negative reciprocal of [tex]\frac{3}{1}[/tex] (which is the same as 3) is [tex]-\frac{1}{3}[/tex].
Example 2: The negative reciprocal of [tex]-\frac{4}{3}[/tex] is [tex]\frac{3}{4}[/tex].
Using this logic, the negative reciprocal of 2, or [tex]\frac{2}{1}[/tex], is [tex]-\frac{1}{2}[/tex]. Therefore, the slope of a line perpendicular to the line [tex]y=2x+5[/tex] is [tex]-\frac{1}{2}[/tex].
I hope this helps!
Does anyone know how to solve this equation?

Answer:
$80
Step-by-step explanation:
You are given the formula ...
P = I/(rt)
and the values I = 20, r = 0.05, t = 5.
Put the numbers in place of the corresponding variables and do the arithmetic.
P = 20/(0.05·5) = 20/0.25 = 80
The amount $80 will generate $20 in interest over 5 years at 5% per year.
This morning, the cafe served 8 coffees in all, 75% of which were regular. How many regular coffees did the cafe serve?
Answer:
6 regular coffees. Thank it if its helpful, thank you!
Step-by-step explanation:
75% of 8 is 6
Reasoning:
75/100*8/1=600/100
600/100=6!
Answer:
Regular coffee served by cafe = 75%* 8
= 75/100*8 = 6 coffees

f(x) = 3 - 2x and g(x) =
1/X+5 what is the value of
(f/g)(8)
9514 1404 393
Answer:
(f/g)(8) = -104/41
Step-by-step explanation:
Fill in the value for x and do the arithmetic.
f(8) = 3 -2·8 = 3 -16 = -13
g(8) = 1/8 +5 = (1+40)/8 = 41/8
Then the ratio is ...
(f/g)(8) = f(8)/g(8) = -13/(41/8) = -13(8)/41
(f/g)(8) = -104/41
In the diagram below, m_MON = 1249, m _ MOP = 2x + 1, and m2 NOP = 2x
+1. What are the exact measures of the angles?
N
A. m2 MOP= 62
m2 NOP = 62
B. m2 MOP = 61
m 2 NOP = 61
C. m MOP = 48
m2 NOP = 72
D. m2 MOP = 122
m 2 NOP = 122
Answer:
The answer is below
Step-by-step explanation:
The Angle Addition Postulate states that the measure of an angle formed by two or more angles which are placed side by side is the sum of the measures of the two angles.
Therefore:
∠MON = ∠MOP + ∠NOP (angle addition postulate)
Substituting values gives:
124 = (2x + 1) + (2x + 1)
124 = 2x + 2x + 1 + 1
124 = 4x + 2
subtracting 2 from both sides of the equation:
124 - 2 = 4x + 2 - 2
4x = 122
Dividing through by 4:
4x / 4 = 122 / 4
x = 30.5
Therefore ∠MOP = 2x + 1 = 2(30.5) + 1 = 62°, ∠NOP = 2x + 1 = 2(30.5) + 1 = 62°
∠MOP = 62°, ∠NOP = 62°

If y(x)=-4x - 5 and x(t)=t^2+ 2t , find y(x(t)).
9514 1404 393
Answer:
y(x(t)) = -4t^2 -8t -5
Step-by-step explanation:
Fill in the argument value and simplify.
y(x(t)) = y(t^2 +2t) = -4(t^2 +2t) -5
y(x(t)) = -4t^2 -8t -5
A sample of 26 elements from a normally distributed population is selected. The sample mean is 10 with a standard deviation of 4. The 95% confidence interval for μ is _____. a. 6.000 to 14.000 b. 8.384 to 11.616 c. 8.462 to 11.538 d. 9.846 to 10.154
Answer:
B. 8.384 to 11.616
Step-by-step explanation:
We have
mean = 10
s = 4
n = 26
the degrees of freedom = n-1
= 26 - 1 = 25
α = 1-95%
= 1 - 0.95
= 0.05
α/2 = 0.05/2 = 0.025
using the t table
t0.025, 25 = 2.06
we find the margin of error
t * s/√n
= 2.06 * 4/√26
= 1.616
10-1.616 < μ < 10+1.616
= 8.384<μ<11.616
therefore option b is the right solution
A two-way frequency table is shown below that displays the relationship between the region of the country in which people live and the type of music preferred.

(
Answer:
13%
Step-by-step explanation:
Given the two way frequency table :
Country Music Rock Total
West 26 15 41
East 24 22 46
South 7 33 40
North 41 25 66
Total 98 95 193
From. The table :
n(West n Country music) = 26
n(Total) = 193
P(West n Country music) = n(West n Country music) / n(Total)
P(West n Country music) = 26 / 193
= 0.1347
= 13.47%
= 13%

Eight pipes were turned on to fill the pool in 36 hours. Then, after 12 hours some of the pipes were turned off, and the rest of the pool was filled in 32 hours. How many pipes were turned off?
Answer:
2 pipes
Step-by-step explanation:
So.. I'm not too sure either, but I'll try to solve it.
Equation: 4x=8 when x=number of pipes turned off after 12 hours
Since there were initially 8 pipes and there are 4 hours between 36 planned hours to fill the whole pool and 32 actual hours passed to fill the rest of the pool, you multiply them.

Give the values of A, B, and C needed to write the equation's general form.
(5 + x)(5 - x) = 7
1. A = 1; B = 0; C = -18
2. A= -1; B = 0; C = 25
3. A = 25; B = 0; C = -1
Given:
The equation is:
[tex](5+x)(5-x)=7[/tex]
To find:
The value of A, B and C for the equation's general form.
Solution:
We have,
[tex](5+x)(5-x)=7[/tex]
Using distribution property, we get
[tex](5)(5)+(5)(-x)+(x)(5)+(x)(-x)=7[/tex]
[tex]25-5x+5x-x^2=7[/tex]
[tex]25-x^2=7[/tex]
Taking all terms on one side, we get
[tex]25-x^2-7=0[/tex]
[tex]-x^2+18=0[/tex]
[tex]-(x^2-18)=0[/tex]
[tex]x^2-18=0[/tex]
On comparing this equation with the general form of a quadratic equation [tex]Ax^2+Bx+C=0[/tex], we get
[tex]A=1[/tex]
[tex]B=0[/tex]
[tex]C=-18[/tex]
Therefore, the correct option is 1.

A train leaves at 15:43 and arrives at 17:13. It travelled at an average speed of 75 km/h.
How far did it travel? Give your answer in km to 1DP.
Can anyone answer this
Answer:
Distance cover by train = 112.5 km
Step-by-step explanation:
Given;
Speed of train = 75 km/h
Time started = 15:43 min
Time ended = 17:13 min
Find:
Distance cover by train
Computation:
Time started = 15:43 min = 15.716 hour
Time ended = 17:13 min = 17.216 hour
Total time taken = 17.216 - 15.716
Total time taken = 1.5 hour
Distance cover by train = Total time taken x Speed of train
Distance cover by train = 75 x 1.5
Distance cover by train = 112.5 km

Answer: Composite figure: 360 ft3
Explanation:
The volume of the triangular prism:
The base area of the prism = 1/2 x 4 x 6 = 12 ft2
Height = 6 ft
The volume of the triangular prism = 12 x 6 = 72 ft3
The volume of the rectangular prism:
The base area of the prism = 4 x 6 = 24 ft2
Height = 12 ft
The volume of the triangular prism = 12 x 24 = 288 ft3
Volume of the composite figure = (288 + 72)ft3 = 360 ft3
