Identify each x-value at which the slope of the tangent line to the function f(x) = 0.2x2 + 5x − 12 belongs to the interval (-1,

Misha Larkins [42]

Answer:

slope of the tangent

$\frac{d y}{d x} = 0.2(2 x) + 5 (1)$

The slope of the tangent to the interval (-1 ,1)

m = 4.6 ,5, 5.4

Step-by-step explanation:

Step(i):-

Given function is f(x) = 0.2 x² + 5 x − 12

Slope of the tangent formula

$m = \frac{d y}{d x}$

Let y = f(x) = 0.2 x² + 5 x − 12 ...(i)

Differentiating equation(i) with respective to 'x' , we get

$\frac{d y}{d x} = 0.2(2 x) + 5 (1) -0$

let x=-1

$m = \frac{dy}{dx} = 0.2 (2 X -1) +5 = 4.6$

let x=0

m = 5

let x=1

$m = \frac{dy}{dx} = 0.2 (2 X 1) +5 = 5.4$

conclusion:-

slope of the tangent

$\frac{d y}{d x} = 0.2(2 x) + 5 (1)$

The slope of the tangent to the interval (-1 ,1)

m = 4.6 , 5, 5.4

The graph of the equation y=2x+b passes through the point (b, -3). Find b. PLZ SHOW WORK!

Sliva [168]

Substitute in the points. It doesn't matter if they ar pe variables or not, since the variable b is used already in the equation, making it possible to find.

Substitute in the y value for the y in the equation and do the same for the x.

-3=2b+b
-3=3b
-1=b

b is -1.

Solve for X: 1/3 (2x - 8)=4.

Veseljchak [2.6K]

Answer:

x = 10

Step-by-step explanation:

1/3 (2x - 8)=4.

Multiply each side by 3

1/3 *3(2x - 8)=4.*3

2x-8 = 12

Add 8 to each side

2x-8+8 =12+8

2x = 20

Divide each side by 2

2x/2= 20/2

x = 10

8. Cory drove 7 miles South on Kings Drive. He then turned East and went another 24 miles down Hwy 66. At this point he turned o

Ilia_Sergeevich [38]

Answer:

Cory drove 56 miles.

Step-by-step explanation:

In order to solve the present problem, the Pythagorean theorem must be used, as the displacements towards the south and east operate as legs and the diagonal return as hypotenuse, forming a right triangle:

7 ^ 2 + 24 ^ 2 = X ^ 2

49 + 576 = X ^ 2

2√625 = X

25 = X

Thus, since he traveled 7 miles south, 24 miles east, and then 25 miles diagonally toward his house, in total he traveled 56 miles (7 + 24 + 25).
