Answer:
(7x^2 -1)(x - 2).
Step-by-step explanation:
7x^3 - 14x^2 - x + 2
We can factor this by grouping - that is factoring the first 2 terms and the last 2:
= 7x^2(x - 2) - 1(x - 2) <-- the x - 2 is common to both parts so we have:
(7x^2 -1)(x - 2).

Answer:
= √b/2a⁴
Step-by-step explanation:
First, we can simplify the ³⁄₁₂ to ¼
Next, we can simplify the a⁻³/a⁵ to a⁻⁸ which is ¹⁄ₐ⁸
Then we can simplify the b²/b to b
Now we should have:
√(b/4a⁸)
= √b/√(4a⁸)
= √b/2a⁴

Find the value of r so the line that passes through each pair of points has the given slope.
Point 1: (-5,r)
Point 2: (1,3)
m = 7/6
Answer:
- 4
Step-by-step explanation:
( 3 - r ) / ( 1 + 5) = 7/6
[tex]\frac{3-r}{1+5}[/tex] = [tex]\frac{7}{6}[/tex] ⇒ 3 - r = 7 ⇒ r = - 4
Which of these is a linear equation in
standard form for the graph shown?
Answer:
B
Step-by-step explanation:
Because the slope is a positive slope (goes through the positive quandrants on the graph), we can eliminate answer choices c. Now, if we solve a, b, and d and we can see if the slope + y-intercept matches the graph.
For A.) (solve for y to get a y=mx + b equation)
3x-2y=4
-2y= -3x + 4
y= 3/2 -2
For B.)
3x-2y= -4
-2y= -4-3x
y= 3/2 + 2
For D.)
2x+3y= 4
3y= 4-2x
y= -2/3x + 4/3
Now, if we look at D, the slope is negative so it cannot be D. That leaves us with A and B. The b in the y=mx + b equation stands for the y-intercept, so we can see that the y-intercept is 2. So, since the graph intersects the y-axis at (0,2), the answer is B! y=3/2 + 2 has a positive slope and 2 for the y-intercept!
The graph shows the number of inches of snow over the course of time.
Which statement is not correct about the relationship shown in the graph?
A It is snowing at a steady rate.
B It is snowing at a rate of inch per hour.
C The amount of snow is proportional to the time.
D The coordinate (2, 1) indicates that it has snowed 2 inches in 1 hour
Correct OPTIONS:
A It is snowing at a steady rate.
B It is snowing at a rate of ½ inch per hour.
C The amount of snow is proportional to the time.
D The coordinate (2, 1) indicates that it has snowed 2 inches in 1 hour
Answer:
D The coordinate (2, 1) indicates that it has snowed 2 inches in 1 hour
Step-by-step explanation:
Using the graph given, let's analyse each options provided to see which statement is ✅CORRECT or ❌ INCORRECT.
A. "It is snowing at a steady rate."
✅This is CORRECT because a straight line graph has a constant rate of change.
B. "It is snowing at a rate of ½ inch per hour."
✅This is CORRECT, because when x (time in hrs) is 1, y (snow in inches) is ½.
C. "The amount of snow is proportional to the time."
✅This is CORRECT because the line of the graph intercepts the point of origin, (0, 0).
D. "The coordinate (2, 1) indicates that it has snowed 2 inches in 1 hour"
❌This is NOT CORRECT. The coordinate (2, 1) indicates that it has snowed 1 inch in 2 hours rather.
x = 2 => time(hours)
y = 1 => snow(inches)

The mean score on a calculus exam was 40 and the standardize deviation was five. The teacher decided to double everyone score and then add seven points. What are the values of the mean and standard deviation of the distribution of transform exam scores
Answer:
The mean will double and add 7, the SD will double
Step-by-step explanation:
If the old mean is x, the new mean will be 2x+7, and since the SD is based on x, the SD for after the curve will based on 2x, so it will also double.

The estimated population is 1242 and the actual population is 1378.
The percent error is approximately
The percentage error is approximately 10%
How to estimate the percent error?We have:
Estimated = 1242
Actual = 1378
The change in the measurement is:
Change = Actual - Estimate
So, we have:
Change = 1378 - 1242
Evaluate
Change = 136
The percentage error is then calculated as:
Percentage error = Change * 100%/Actual
This gives
Percentage error = 136 * 100%/1378
Evaluate
Percentage error = 9.869%
Approximate
Percentage error = 10%
Hence, the percentage error is approximately 10%

y - 6 = 4 ( x - 4 )
Step-by-step explanation:
First, we need to get it to slope-intercept form:
So you distribute the 4 to x-4:
4x-16
now the equation looks like this:
y-6=4x-16
now move the -6 to the other side:
y=4x-10
Answer:
The graph of the equation y - 6 = 4(x - 4) is attached at the end.
To graph the equation y - 6 = 4(x - 4), rewrite it in slope-intercept form by solving for y:
y - 6 = 4(x - 4)
y - 6 = 4x - 16
y = 4x - 16 + 6
y = 4x - 10
Now, the slope (m) is 4 and the y-intercept (b) is -10.
To graph the equation, plot a few points and draw a straight line passing through those points.
Choose some x-values and calculate the corresponding y-values:
For x = 0, y = 4(0) - 10 = -10
For x = 2, y = 4(2) - 10 = -2
For x = 4, y = 4(4) - 10 = 6
For x = 6, y = 4(6) - 10 = 14

The time (in minutes) required to learn the procedure for performing a certain task is uniformly distributed on the interval from 32 minutes to 52 minutes. (a) What is the probability that it takes more than 46 minutes to learn the procedure?(b) What is average time reqiured to learn the procedure?
Answer:
a
[tex]P( X > 46) = 0.7 \ minute[/tex]
b
[tex]\mu = 42 \ minute[/tex]
Step-by-step explanation:
From the question we are told that
The procedure for performing a certain task is uniformly distributed on the interval from( a = 32 )minutes to (b= 52) minutes
Generally the cumulative distribution function for continuous uniform distribution is
[tex]F(x) = \left \{ {{0 \ \ \ \ \ for \ x \ x < a} \atop {\frac{x-a}{b-a} } \ \ for \ a \le x \ge b} \atop {1 \ \ \ \ \ \ \ for \ x > b }\right.[/tex]
Generally the probability that it takes more than 46 minutes to learn the procedure is mathematically represented as
[tex]P( X > 46) = F(46) = \frac{46 - 32}{52-32}[/tex]
=> [tex]P( X > 46) = 0.7 \ minute[/tex]
Generally the average time required to learn the procedure is mathematically represented as
[tex]\mu = \frac{a + b}{2}[/tex]
=> [tex]\mu = \frac{32 + 52}{2}[/tex]
=> [tex]\mu = 42 \ minute[/tex]

divide a line of 1.8m into three parts in the ratio of 5:7:8
Answer:
0.45 m, 0.63 m, 0.72 m
Step-by-step explanation:
Let the three parts of the line be 5x, 7x and 8x
Therefore,
5x + 7x + 8x = 1.8
20x = 1.8
x = 1.8/20
x = 0.09
5x = 5*0.09 = 0.45 m
7x = 7*0.09 = 0.63 m
8x = 8*0.09 = 0.72 m

A train leaves the station at time t=0. Traveling at a constant speed, the train travels 280 kilometers in 2 hours. Answer parts a and b.
a. Write a function that relates the distance traveled d to the time t.
The function that relates the distance traveled d to the time t is
Answer:
d = 140t
Step-by-step explanation:
The function that relates the distance travelled d to the time t is d = f(t) = 140t.
What is Speed?Speed is a scalar quantity which measures the rate of change of the position of an object without measuring on the direction.
In other words, it can be defined as the ratio of distance covered by an object to the time taken by the object to cover the distance.
The train leaves the station at time t = 0.
Distance travelled by the train = 280 kilometers
Time taken to travel the distance = 2 hours
Speed = Distance / Time
= 280 / 2
= 140 kilometers/ hour.
Given that train travels at a constant speed.
So for any distance 'd' and the time taken to travel the distance 't',
d / t = 140
d = 140t
d = f(t) = 140t
Hence the distance travelled by the train can be related to the time taken by the function, d = f(t) = 140t
