Answer:

At the point where x = 2.

Step-by-step explanation:

First find the derivative which gives us the gradient of the tangent at any point on the curve:

y = 5x^2 - 16x

y' = 5*2 x^(2-1) - 16 x(1-1)

y' = 10x - 16.

y' is the gradient at point of coordinate x.

So when the gradient = 4:

4 = 10x - 16

10x = 20

x = 2.

6x - 2y = 5

laiz [17]

Answer:

The given system has NO SOLUTION.

Step-by-step explanation:

Here, the given system of equation is:

6 x - 2 y = 5 .......... (1)

3 x - y = 10 .... (2)

Multiply equation 2 with (-2), we get:

3 x - y = 10 ( x -2)

⇒ - 6 x + 2 y = - 20

Now, ADD this to equation (1) , we get:

6 x - 2 y - 6 x + 2 y = 5 - 20

or, 0 = - 15

WHICH IS NOT POSSIBLE as 0 ≠ -15

Hence, the given system has NO SOLUTION.

Answer:

Option C is correct.

$38 miles$

Step-by-step explanation:

Let x be the distance cover by Michelle

Given:

A circle diameter is 3 miles.

And Michelle biked around the trail 4 times.

We know that

The circumference of a circle.

circumference = $2\pi r$ ----------(1)

where $r=\frac{Diameter}{2}$

$r=\frac{3}{2} \\r=1.5$ miles

Put $\pi =3.14$ and r value in equation 1.

$circumference = 2\times 3.14 1.5$

$circumference = 9.42 mil;es$

The circumference of a circle is 9.42 miles.

And Michelle biked 4 times, that is equal to 4 $\times$ circumference.

$x = 4\times 9.42$

$x = 37.65 miles$ .

That is equal to 38 miles.

Therefore, Michelle biked around 4 trail is 38 miles.
