Aball is thrown into the air by a baby alien on a planet in the system of alpha centauri with a velocity of 43 ft/s. its height in feet after t seconds is given byy=43t-23t^{2}.
a. find the average velocity for the time period beginning when t=1 and lasting
.01 s:
.005 s:
.002 s:
.001 s:
note: for the above answers, you may have to enter 6 or 7 significant digits if you are using a calculator.
b. estimate the instanteneous velocity when t=1.

Instantaneous Velocity at t = 1 is 20 feet per second

Step-by-step explanation:

We are given he following information in the question:

B) Instantaneous Velocity at t = 1

A) Formula:

Average velocity =

1) 0.01

2) 0.005 s

3) 0.002 s

4) 0.001 s

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
