The formula to find the zero of linear polynomial in the form of y=ax+b is
Answer:
X = - b / a
Step-by-step explanation:
point 1 and -2 lies in the dash quadrant
Given:
The point is (1,-2).
To find:
The quadrant in which the point (1,-2) lies.
Solution:
We know that,
In first quadrant, both coordinates are positive, i.e., (x,y).
In second quadrant, x coordinate is negative but the y-coordinate is positive, i.e., (-x,y).
In third quadrant, both coordinates are negative, i.e., (-x,-y).
In fourth quadrant, x coordinate is positive but the y-coordinate is negative, i.e., (x,-y).
Where, x and y are two non-negative values.
In the given point (1,-2) the x coordinate is positive but the y-coordinate is negative.
Therefore, the point (1,-2) lies in fourth quadrant.
Select all the correlation coefficients that represent a linear model with a weak correlation .
A. -0.982
B. -0.618
C. -0.103
D. 0.204
E. 0.907
F. 1
Answer:
C) -0.103 and D) 0.204
Step-by-step explanation:
A linear model with a weak correlation is gonna have an r value closest to 0, whether it be negative or positive. C and D seem to be the best choice as they're closest to 0.

What is the slope of the line represented by -3x + 5y = 20 ?
A trapezoid has a height of 6 inches, an area of 120 square inches, and one base measuring 13 inches. Find the length of the other base.
Answer:
27
Step-by-step explanation:
Givens
b1 = 13
b2 = ?
h = 6
Area = 120
Formula
Area = (b1 + b2) * h/2 Multiply by 2
2Area = (b1 + b2)*h Divide by h
2Area/h = b1 + b2 Subtract b1 from both sides
2Area/h - b1 = b2
Solution
2*120 / 6 - 13 = b2
40 - 13 = b2
b2 = 27

Write the equation of a circle with a center of (1,-2) and radius of 4.
Answer:
(x - 1)^2 + (y + 2)^2 = 4^2
Step-by-step explanation:
The standard equation of a circle of radius r with center at (h, k) is
(x - h)^2 + (y - k)^2 = r^2
Replacing h with 1, y with -2 and r with 4, we get:
(x - 1)^2 + (y + 2)^2 = 4^2
What number am I? All of my digits are even. My tens digit is equal to two more than my hundreds digit. My ones digit is equal to two more than my tens digit.
Answer:
246 or 468.
Step-by-step explanation:
The only possible even digits are 2, 4, 6, and 8 (0 is neither even nor odd).
Therefore, your possible numbers are 246 and 468.
You go completely unprepared for a multiple choice quiz. The quiz has five questions, each with four answer choices. Describe a simulation that you could use to determine the experimental probability of guessing all five questions correctly.

Thats common sense
Answer:
Step-by-step explanation:
Computer languages love this kind of question. You could run it a million times and the computer would bring back an answer in under 10 seconds.
Let us suppose that 4 is the correct answer for all 5 questions.
Run the simulation 1000000 times. There is only 1 answer that is acceptable
select a random number from 1 to 4
do this 5 times
If all five random numbers are 4 then add 1 to counter which keeps track of the number of times 4 was chosen 5 times (it will be pretty small).
End by displaying the number of times 4 was chosen 5 times
Divide by 1 million.
In running the simulation, I described using Delphi it ran the simulation in under 1 second. That is, took the test 1 million times.
I'm going to save this answer and if I can edit the question I'll tell you what I got. If not, I suppose I could put it in a comment.
The experimental answer I got was 993 which is awfully close to 1/1000 which is approximately the theoretical answer. So my simulation that I described will work really well.
The theoretical answer is
1/4 * 1/4 * 1/4 * 1/4 *1/4 = 1 / 1024 So actually 1/1000 (which my simulation nearly got) is really kind of close.
There are other ways of doing this simulation.

Find the area of the trapezoid.
Answer:
78 ft squared
Step-by-step explanation:
To find the area of trapezoid, we could use this formula:
.5*height*(sum of bases)
We know both the base lengths. They are 10 and 16 ft.
The height can be found by looking at that right triangle whose base is (16-10) ft or 6 ft.
So we want to find the height which is opposite the 45 degree angle and we have the adjacent side's measurement of 6ft.
This has the tangent ratio written all over it since tangent of an angle is opposite side's measurement over adjacent side's measurement.
tan(45)=height/6
1=height/6
6=height
6ft=height
The answer is:
.5*height*(sum of bases)
.5*6 ft*(10 ft+16 ft)
3 ft(26 ft)
78 ft squared
Note: That one right triangle is an isosceles right triangle so we didn't need trigonometry.
someone help please :(
Answer:
D
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift left of a units
• If a < 0 then a shift right of a units
Then
g(x + 3)² is the graph of f(x) translated 3 units left
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Then
g(x) = g(x + 3)² - 7 is the graph of f(x)
Translated 3 units left and 7 units down
What is the absolute maximum or minimum of f(x) = 3x^2-5x-9
Answer:
Absolute minimum / vertex = (5/6,-133/12)
Step-by-step explanation:
Since a is positive, then the absolute maximum is ∞. The absolute minimum would be the vertex of the parabola, meaning x=-b/2a=-(-5)/2(3)=5/6, and y=3(5/6)^2-5(5/6)-9 = -133/12. Therefore, your absolute minimum / vertex is (5/6,-133/12)

The triangle below has a perimeter of 20. Solve for x
Answer:
x = 5
Step-by-step explanation:
Given that,
First side of a triangle = x+2
The second side of a triangle = 8
The third side of a triangle = x
We know that, perimeter is equal to the sum of all sides. So,
x+2+x+8 = 20
2x+10 = 20
2x = 10
x = 5
Hence, the value of x is equal to 5.
A westbound train travels 16 miles per hour slower than the eastbound train. If two trains are 800 miles apart after 5 hours what is the rate of the westbound train?
Answer:
6
Step-by-step explanation:
The rate can be calculated as follows
x + x -16
2x-16
(2x-16)×5
10x - 80= 800
10x = 300-80
10x, = 220
x = 220/10
= 22
22-16
= 6 mph
Hence the rate of the west bound tsin is 6mph

Answer:
t ≤ 10
Step-by-step explanation:
To solve the inequality, simplify it.
-3t + 9 ≥ -21
Subtract 9 from both sides.
-3t ≥ -30
Divide by -3. When dividing by a negative, flip the inequality sign.
The answer is C, t ≤ 10.
