Given:

Point 1 → (-5, 0.6)

Point 2 → (5, -2.4)

Find: the equation of the line and its graph

Solution:

To help us determine the equation of the line passing through the given points, let's use the Two-Point Form formula.

Let's plug into the formula above the coordinates of the two points.

Then, solve.

Multiply -3/10 by the terms inside the parenthesis.

Add 0.6 on both sides of the equation.

Hence, the equation of the line passing through the given points in slope-intercept form is y = -0.3x - 0.9.

In the equation, the slope is -3/10 while the y-intercept is -0.9.

Since the slope is negative, the line must be leaning to the left. Since the y-intercept is -0.9, the line must cross the y-axis or the vertical line at -0.9. Hence, the graph of the equation is:

Since a positive number divide or multiplies a negative number

Then the answer will be a negative number

So:

6 / -3 = -2

6 is a positive number and it's being divide by -3 which is a negative number

So the answer is -2

Given.

The distance covered by the snail in 4 minutes is 10 cm.

The speed of snail is,

The distance covered by snail in 6 minute is,

Hence, the distance covered by the snail is 15 cm.

Speed :

Speed is defined as the rate at which an object's position changes in any direction. Speed is defined as the ratio of distance traveled to time spent traveling.

Hence , speed can be calculated by using the formula,

               Speed = [tex]\frac{Distance-travelled}{Time-taken}[/tex]

Given data :

Distance travelled by the snail = 10 cm = 0.1 m

Time taken by the snail to travel a distance of 10 cm = 4 min = 240 s

Then , speed of the snail = [tex]\frac{10}{4}[/tex] = 2.5 cm/min = 0.0004 m/s

If the time taken by the snail is 6 min = 360 s

Then, the distance travelled by the snail in 6 min

         = speed x time taken

          = 2.5 cm/min  x 6 min

          = 15 cm = 0.15 m.

Therefore, the snail travels a distance of 15 cm in 6 min.

Work done in stretching spring from 36 cm to 38 cm is 0.333J.

The work needed to stretch a spring is given by the formula mentioned below:

[tex]W_{s}[/tex] = (1/2) K × [tex]x^{2}[/tex]

Here,  k is spring constant and x is the elongation.

So, x = [tex]x_{f} - x_{i}[/tex]

When spring is stretched from 40 cm to 34 cm

x = 40 - 34  = 6cm = 0.06 m

We need to know the spring constant so that we can calculate work.

3 = (1/2) K × [tex](0.06)^{2}[/tex]

K = 1666.67

Now, when spring is stretched from 36 cm to 38 cm

x = 38 - 36 = 2 cm = 0.02 m

[tex]W_{s}[/tex] = (1/2) × (1666.67) × [tex](0.02)^{2}[/tex]

[tex]W_{s}[/tex] = 0.333J

So, 0.333J work is done in stretching spring from 36 cm to 38 cm.

8.27 is the normally distributed value of the shelf life which falls under 16% of the battery shelf life.

Because the shelf life of a battery manufactured by one big business is known to be regularly distributed, we would use the normal distribution formula, which is stated as

z = (x - µ) ÷ σ

Where

x = shelf life of a battery in years.

µ = mean shell life

σ = standard deviation

Based on the facts provided,

µ = 8 years

σ = 0.3 years

The z score corresponds to a p-value of 16% in the normal distribution table,

(16 ÷ 100 = 0.16) is - 0.9.

Therefore,

- 0.9 = (x - 9) ÷ 0.3

0.3 × (- 0.9) = x - 8

0.27 = x - 8

x = 0.27 + 8

x = 8.27

1) Gathering the data

1/5 inch

7/20 inches long

2) Let's them divide, 7/20 by 1/5 inches

When divide fractions, we multiply the reciprocal of the second fraction

and if possible we can simplify

The correct option regarding the symmetry of the distribution is given as follows:

The data is skewed right, with fewer values on the right end of the graph. The values at 62 and 89 are possible outliers. The data fits within the average of 60 to 100 beats per minute.

To find the symmetry of the distribution, the mean and the median need to be calculated and compared, if they are equal or which is greater.

A dot plot shows the number of times that each observation appears in the data-set, hence the complete data-set of heart beats per minute is given as follows:

62, 68, 68, 68, 69, 70, 70, 72, 72, 72, 75, 75, 76, 78, 78, 80, 80, 80, 89, 89.

The mean is the sum of all these observations divided by the number of observations, which is of 20, hence:

Mean = (62 + 3 x 68 + 69 + 2 x 70 + 3 x 72 + 2 x 75 + 76 + 2 x 78 + 3 x 80 + 2 x 89)/20 = 74.55.

The median is the middle value of the data-set, the value which 50% of the observations are less than and 50% are greater than. The cardinality of 20 in this data-set is an even number, hence the median is the mean of the 10th and of the 11th element, as follows:

Median = (72 + 75)/2 = 73.55.

When the mean is greater than the median, as is the case in this problem, the distribution is right skewed, which is the reason for the correct option.

The given  polynomial function f(x)=x^3 - 2x^2 - 5x + 6 as a product of linear factors as (x+2).(x-3).(x-1)

In the above question, a polynomial function is given

f(x)=x^3 - 2x^2 - 5x + 6

However, we know that, zero of a polynomial means all the x-values that bring a polynomial, p(x), to zero are referred to as its zeros, which means putting any value of x in the function we should get value of f(x) as zero

And, in the question, it is given as

f(0)=6, f(2) = -4, f(-2) = 0, f(3) = 0 , f(-1) = 8 , f(1) =0

We can clearly see that,  f(-2) = 0, f(3) = 0, f(1) =0

=> (x+2), (x-3), (x-1) are the linear factors of the given polynomial
