point 1 = ( -1 , 5 )       point 2 = ( 5 , -5 )

equation of a line:       y = mx + b

Find Slope (m):

( 5 - (-5)) / (-1 - 5))

= 10 / -6

= -3 / 2

slope = -3/2


Find y-intercept (b):

y = mx + b

y = -3/2 * x + b

5 = -3/2 * -1 + b          <--------------  use the x and y coordinate of one of the                                                                                  .                                                                        points. I used point 1 ( -1 , 5 )

b = 7/2 or 3.5


Assemble:

y = -3/2 * x + 3.5

a. Verify that the given point lies on the curve. b. Determine an equation of the line tangent to the curve at the given point.
xxMikexx [17]

Answer:

y = 13*( -x/9 + 1/5)

Step-by-step explanation:

Given:

- The curve has an equation as follows:

                               44 = 5x^2 + 3xy + 3y^2

Find:

a. Verify that the given point (2​,2​) lies on the curve.

b. Determine an equation of the line tangent to the curve at the given point.

Solution:

- To verify whether the point lies on the given curve we will substitute the coordinates of the point into the equation as follows:

                              44 = 5*(2)^2 + 3*(2)(2) + 3*(2)^2

                              44 = 20 + 12 + 12

                              44 = 44 ......Hence proven.

- The equation of the line tangent to the curve is expressed as a linear function as follows:

                              y = m*x + C

Where, m is the gradient of the line.

            C is the y-intercept.

                              m = Δy / Δx = dy/dx

- We will take the derivative of the given curve with respect to x as follows:

                             0 = 10x + 3*( y + xy' )  + 6y*y'\\\\-10x - 3y = y' ( 3x + 6y)\\\\ y' = - \frac{10x + 3y}{3x + 6y}

- Evaluate y' at the point (2,2) we get:

                            y' = - ( 10(2) + 3(2) ) / ( 3(2) + 6(2) )

                            y' = - ( 26 ) / (18)

                            y'= m = - 13/9

- To evaluate C, we will use the point (2,2) for linear expression above with m as follows:

                            y = -13*x/9 + C

                            2 =-13*(2)/9 + C

                            C = 13 / 5

- The equation of the tangent is as follows:

                            y = 13*( -x/9 + 1/5)

Question 1. Which of the following is not true for the equation six times d equals twelve?
Deffense [45]
Q1. The answer is To solve, you must divide both sides by 6

The equation is:   6d = 12
<span>Multiplication is the inverse operation: TRUE -         6d = 12      d = 12/6
Checking the solution involves multiplication: TRUE -    6 * 2 = 12
The equation represents the number that gives twelve when multiplied by 6: TRUE     d is </span>the number that gives twelve when multiplied by 6<span>
To solve, you must divide both sides by 6: false


Q2. The answer is 18
</span><span>
x - the number of students

The students were divided equally among 3 chaperones: 3 chaperones per x
Each chaperone supervised 6 students: 1 chaperone per 6 students
 
3 : x = 1 : 6
x = 3 * 6 : 1
x = 18


Q3. The answer is </span><span>t is greater than or equal to five.
</span>
It will take Harlon at least five years to complete his college degree. The key word is at least. This means that it can include number 5 as well. He may need 5 years, 6 years, 7 years,... Hence, t is greater than or equal to five.


Q4. The answer is <span>1.2
</span>
<span>p over zero point three + 2 = 6
p/0.3 + 2 = 6

multiply both sides by 0.03
p + 2 * 0.3 = 6 * 0.3
p + 0.6 = 1.8
p = 1.8 - 0.6
p = 1.2


Q5. The answer is 2.

</span><span>16w = 32

Divide both sides by 16
16w/16 = 32/16
w = 2</span>

Bobby is testing the effectiveness of a new cough medication. There are 100 people with a cough in the study. Seventy patients r
Tresset [83]

Answer:

0.665

Step-by-step explanation:

Given:  100 people are split into two groups 70 and 30.  I group is given cough syrup treatment but second group did not.

Prob for a person to be in the cough medication group = 0.70

Out of people who received medication, 34% did not have cough

Prob for a person to be in cough medication and did not have cough

=\frac{0.70(34)}{60}=0.397


Prob for a person to be not in cough medication and did not have cough

=\frac{0.3(20)}{30}=0.20

Probability for a person not to have cough

= P(M1C')+P(M2C')

where M1 = event of having medication and M2 = not having medication and C' not having cough

This is because M1 and M2 are mutually exclusive and exhaustive

SO P(C') = 0.397+0.2=0.597

Hence required prob =P(M1/C') = \frac{0.397}{0.597}=0.665
