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

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:

d = 140t

Step-by-step explanation:

The function that relates the distance travelled d to the time t is d = f(t) = 140t.

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

Step-by-step explanation:

thats how math works?

Answer: 5

Step-by-step explanation:

1. 3x+2=17

2. 3x+2-2=17-2 ( we subtract 2 from both sides)

3. then we simplify 3x=15

4. \frac{3x}{3}=\frac{15}{3} then i divide both sides by 3

5.  and as we simplify, x=5

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

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 percentage error is approximately 10%

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%

Your answer would be 5.5

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!

Answer:

At time, 10 seconds, the mass remaining is 24 grams

At time, 20 seconds, the mass remaining is 12 grams

At time, 30 seconds, the mass remaining is 6 grams

At time, 40 seconds, the mass remaining is 3 grams

At time, 50 seconds, the mass remaining is 1.5 grams

Step-by-step explanation:

Given;

initial mass of the radioactive element  = 48 grams

half life, t = 10 seconds

time of decay (s)                          remaining mass of the  radioactive element

0 ------------------------------------------------- 48 grams

10------------------------------------------------- 24 grams

20 ------------------------------------------------- 12 grams

30 -------------------------------------------------- 6 grams

40 --------------------------------------------------- 3 grams

50 ----------------------------------------------------- 1.5 grams

60------------------------------------------------------0.75 grams

Thus;

At time, 10 seconds, the mass remaining is 24 grams

At time, 20 seconds, the mass remaining is 12 grams

At time, 30 seconds, the mass remaining is 6 grams

At time, 40 seconds, the mass remaining is 3 grams

At time, 50 seconds, the mass remaining is 1.5 grams

If these are ratios, then

2:7 = 6:21

Answer:

fraction = 2/7

Step-by-step explanation:

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

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)
