Answer:

The equation form is, a(t)=-1000t+32800    

Step-by-step explanation:

Given : After descending for 8 minutes, an airplane is at an altitude of 24800 feet. After 20 minutes, the plane's altitude is 12800 feet.

To find : Write an equation in the form a(t)=mt+b that shows the altitude, a, after t minutes of descent ?

Solution :

The equation is in form, a(t)=mt+b

Where, 't' is the time in minutes and 'a' is the altitude,

After descending for 8 minutes, an airplane is at an altitude of 24800 feet.

i.e. a=24800 and t=8

Substitute in the equation,

24800=m(8)+b

24800=8m+b ......(1)

After 20 minutes, the plane's altitude is 12800 feet.

i.e. a=12800 and t=20

Substitute in the equation,

12800=m(20)+b

12800=20m+b ......(2)

Solving (1) and (2) by subtracting them,

24800-12800=8m+b-(20m+b)

12000=8m+b-20m-b

12000=-12m

m=\frac{12000}{-12}

m=-1000

Substitute in equation (1),

24800=8(-1000)+b

24800=-8000+b

24800+8000=b

b=32800

So, The equation form is, a(t)=-1000t+32800

WHAT THE HECC IS THIS
anyanavicka [17]

Answer:

h(x)

Step-by-step explanation:

to solve for an inverse, you swap the x and the y and then solve for y

f(x) = 4x^3-8

y = 4x^3 - 8

x = 4y^3 - 8   swap the x and y

now solve for y:

x + 8 = 4y^3

(x + 8)/4 = y^3

1/4x + 8/4 = y^3

1/4x + 2 = y^3

y = \sqrt[3]{1/4x + 2}

Make a conjecture: How many solutions does a quartic equation x 4 + ax 3 + bx 2 + cx + d = 0 have? Explain.
Ratling [72]

Answer:

Four

Step-by-step explanation:

The degree of a polynomial is the highest of the degree of the monomials with non-zero co-efficient. In this problem we are given the polynomial:

                 $ x^4 + ax^3 + bx^2 + cx + d = 0 $

The degree of the polynomial is 4.

For a polynomial of <em>n- degree </em>we have <em>n solutions counting multiplicity</em>.

So for this four degree polynomial we would have 4 solutions. Could be real or complex depending on the equation.
