Answer:

256/3 pi units^3

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3  where r is the radius

V = 4/3 pi (4)^3

V = 256/3 pi units^3

Find an equation of the tangent to the curve at the point corresponding to the given value of the parameter. x = t7 + 1, y = t8
Jet001 [13]
I must assume that you meant t=1 (not t=?1).  If t=1, here's what we'd do:

1.  Find the x and y values corresponding to t=1.  They are:
      x=(1)^7+1=2     and    y=(1)^8+1=2.  (Please note:  write t^8 instead of t8,                and write t^7 instead of t7.)
2.  The slope of the tangent line to the graph is
                          dy/dt            8t^7+1
          dy/dx = ----------   = ---------------- with 1 substituted for t
                         dx/dt              7t^6
  
      Thus, dy/dx (at t=1) = 9/7

3.  Now we have both a point (2,2) on the graph and the slope of the tangent line to the curve at that point:  9/7

4.  The tangent line to the curve at (2,2) is  found by using the point-slope formula:

y-y1 = m(x-x1)

which comes out to y-2 = 9/7(x-2), or 7y-14 = 9(x-2).  You could, if you wished, simplify this result further (e. g., by solving for y in terms of x).

If ABCD (shown below) is a parallelogram, what is the measure of angle ABC?​ ​
yarga [219]

Answer:

B

Step-by-step explanation:

  • From the property of parallelogram the opposite angels are equal so < DAB = < DCB so < DAB will become 16x.

9x + 5 + 16x(<DAB) = 180 ....... because it is straight line.

25x + 5 = 180

25x = 180 - 5

25x = 175

\frac{25x}{25}  =  \frac{175}{25}

x = 7

  • now let's substitute in the angle < DCB( 16x):-16 × 7= 112
  • To get < ABC lets use the property of parallelogram which says tha adjacent angles are supplementary. which means <ABC + <DCB = 180

<ABC + 112 = 180

< ABC = 180 - 112

< ABC = 68

IT WAS SO DIFFICULT TO EXPLAIN WITH PHONE BUT I TRIED MY BEST

hope it helps
