Answer:

The equation of the line in standard form is:

6x + y = 62

Step-by-step explanation:

Given the points

  • (10,2)
  • (14,-22)

Determining the slope between (10, 2) and (14, -22)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(10,\:2\right),\:\left(x_2,\:y_2\right)=\left(14,\:-22\right)

m=\frac{-22-2}{14-10}

m=-6

The point-slope form of the line equation is  

y-y_1=m\left(x-x_1\right)

where

  • m is the slope of the line
  • (x₁, y₁) is the point

substituting the values m = -6 and the point (10, 2) in the point-slope form of the line equation

y-y_1=m\left(x-x_1\right)

y - 2 = -6(x - 10)

y - 2 = -6x +60

adding 2 to both sides

y-2+2 = -6x + 60 + 2

y = -6x +  62

We can write the equation in the standard form such as

Ax + By = C

Thus,

y = -6x +  62

adding -6x to both sides

6x + y = -6x + 62 + -6x

6x + y = 62

Therefore, the equation of the line in standard form is:

6x + y = 62

The slope f '(x) at each point (x, y) on a curve. y = f (x) is given along with a particular point (a, b) on the curve. Use this
Advocard [28]

Answer:

Step-by-step explanation:

Integrating each term with respect to x, we get:

            x^3          x^2

f(x) = 9--------- + 4------- - 4x + C

               3            2

We are told that if x = 0, f(x) = -7, and so C must equal - 7.  

The solution is

            x^3          x^2

f(x) = 9--------- + 4------- - 4x - 7,   or   f(x) = 3x^3 + 2x^2 - 4x - 7

               3            2

The figure is not drawn to scale.
Goryan [66]

Answer:

93°, 89°, 93°

Step-by-step explanation:

∠1 and ∠4 are supplementary angles:

m∠1 + m∠4 = 180°; m∠1 = 93°

∠2 and ∠4 are vertical angles:

m∠2 = m∠4 = 87°

∠3 and ∠4 are supplementary angles:

m∠3 + m∠4 = 180°; m∠3 = 93°

statuscvo [17]

Part A)

His sample only involves days during the summer (if Devin is in the northern hemisphere), which would mean that the high temperatures he'll record are likely to be higher than the average. Therefore, the sample mean he computes does not represent the average high temperature for the whole year.

----------------------------------------

Part B)

To correct his mistake, he needs to sample every day of the year. Or he could sample a few days of each month (say the first ten days of each month). That way the entire year is better represented. The other seasons of spring, fall and winter are included now.
