Find the point on the curve y = √ x where the tangent line is parallel to the line y = x 8 .
vichka [17]
If tangent to the curve y = √x  is parallel to the line  y = 8x,  then this implies that the tangent to  y = <span>√x  has the same slope as the line  y = 8x. In other words, the derivative (slope) function of  y = √x  is equal to the slope of the line  y = 8x, which is m = 8.  Hence y' = 8  once we find  y'

y =  </span><span>√x = x^(1/2)

Applying the power rule and simplifying, we find that the derivative is

y' = 1/(2</span>√x)

Now remember that  y'  must equal 8

1/(2<span>√x) = 8

Multiplying both sides by  2</span><span>√x,  we obtain

1 = 16</span><span>√x

Dividing both sides by  16,  yields

</span><span>√x = 1/16

But wait a minute, √x = y.  Thus  1/16  must be the y-coordinate of the point at which the tangent to  y = √x  is drawn.

Squaring both sides, yields

x = 1/256 

This is the x-coordinate of the point on the curve where the tangent is drawn.

</span><span>∴ the required point must be  (1/256, 1/16)

GOOD LUCK!!!</span>

Find the rectangular coordinates of (7, 150°)
Y_Kistochka [10]

Answer:

The coordinates are (-7sqrt(3)/2, 7/2).

Step-by-step explanation:

The rectangular coordinates from polar coordinates is found by:

x = r*cos(theta)

y = r*sin(theta)

Substituting the given values, we get:

x = 7*cos(150 deg) = 7*(-sqrt(3)/2) = -7sqrt(3)/2

y = 7*sin(150 deg) = 7*(1/2) = 7/2

The coordinates are (-7sqrt(3)/2, 7/2).

I hope this helps! :)

Find the vertex of the graph and the axis of symmetry
ale4655 [162]
How to do the vertex is using the formula -b/2a

your a=-9 and b is -18 but it going to become +18 because you are multiplying the -(-18) which there a 1 in front the neg. you going to multiply the -9 by 2 and do 18/18 so your x= -1. You got your x, you going to put in the equation as y=-9(-1)^2-18(-1)-1 then you got your y... hope this is helpful :)

What is the solution to this system of equations?<br><br> -5.9x-3.7y=-2.1<br> 5.9x+3.7y=2.1
marin [14]

Answer:

There are infinite solutions that solve the system y=0.57-1.59x

Step-by-step explanation:

  • The solution can be expressed as y=0.57-1.59x (there are infinite solutions that solve the system). This results from rearranging terms in the first or second equation.
  • This is because the first equation is a linear combination of the second one (this is, the first equation equals (-1) times the second equation). This means that the second equation does not add any information about x and y: it says exactly the same as the first equation about the relationship between x and y.
  • Then, in terms of solving the system, you have one unique expression (not repeated) that shows the relationship between y and x. This means that, any pair of (x,y) that meet the requirements expressed by y=0.57-1.59x, will solve the system. Then we have infinite solutions.
