Answer:

x = -2, 4

Step-by-step explanation:

4(x-1)^2 + 2 = 38

Subtract 2 from each side

4(x-1)^2 + 2-2 = 38-2

4(x-1)^2  = 36

Divide each side by 4

4/4(x-1)^2  = 36/4

(x-1)^2  = 9

Take the square root of each side

sqrt((x-1)^2 ) =±sqrt( 9)

x-1 =

Add 1 to each side

x-1 +1= 1 ±3

x = 1 ±3

x = 1+3 = 4

   1 - 3 = -2

Find the coordinates of x−intercept and of y−intercept of the line. y=−3x−9
My name is Ann [436]

Answer:

(-3, 0), (0, -9)

Step-by-step explanation:

x-intercept:  Let y = 0 and find x:  0 = -3x - 9), or 3x = -9.  Then x = -3, and the x-intercept is (-3, 0).

y-intercept.  Let x = 0 and find y.  y = -3(0) - 9 = -9.  The y-intercept is (0, -9).

What is the equation of the tangent line passing through the point (0, 3) of the graph of the function f(x) = x2 − 2x + 3?
Sergeeva-Olga [200]

Answer:

y = -2x + 3

Step-by-step explanation:

The given equation is:

f(x)=x^2-2x+3

First we need to find the slope of the tangent line. This can be done by finding the derivative of the given function.

f'(x)=2x-2

Slope of the tangent will be the value of the derivative at the given point. So the slope of tangent is:

f'(0)=2(0)-2=-2

Now we have slope of the tangent line and a point (0, 3) on the tangent. The point (0,3) is the y-intercept of the tangent line. So we can use slope-intercept form to directly write the equation of the line.

The slope intercept form of an equation is:

y = mx + c

where m is the slope and c is the y-intercept.

Using the values: m = -2 and c = 3, we get:

y = -2x + 3

This equation represents the tangent line

Meaning of cube root
Nesterboy [21]

Answer:

The cube root of a number is a special value that, when used in a multiplication three times, gives that number. Example: 3 × 3 × 3 = 27, so the cube root of 27 is 3. See: Square Root. Cubes and Cube Roots.

The sum of two numbers is 5000. if 20% of one number is equal to 30% of other no. find the number
Alex Ar [27]
W +Y =5000

20/100 x W=   30/100 X Y

W/5=3Y/10

10W=15Y

W=15Y/10=3Y/2

3Y/2+Y=5000

3Y+2Y=10,000

5Y=10,000

Y=2000

AND HENCE W=3 x2000/2=3000
