Select all the correct equations.

Answer:

You did not post the options, but i will try to answer this in a general way.

Because we have two solutions, i know that we are talking about quadratic equations, of the form of:

0 = a*x^2 + b*x + c.

There are two easy ways to see if the solutions of this equation are real or not.

1) look at the graph, if the graph touches the x-axis, then we have real solutions (if the graph does not touch the x-axis, we have complex solutions).

2) look at the determinant.

The determinant of a quadratic equation is:

D = b^2 - 4*a*c.

if D > 0, we have two real solutions.

if D = 0, we have one real solution (or two real solutions that are equal)

if D < 0, we have two complex solutions.

Anderson has $50 in his savings account. He deposits $5 every week. His father also deposits $20 into the account every time And

Sav [38]

Part A: 5 is the coefficient, w is the variable, 50 is the constant

Part B: 10 x 5 = 50 + 2 x 20 = 40+ 50 = $140

Part C: the constant,50,would change and become 85. Hope this helps :)

An amusement park ride rotates around a fixed axis such that the angular position of a point on the ride follows the equation: θ

pshichka [43]

I found a missing question online. What is the magnitude of the angular displacement of the ride in radians between times t=0 and t= t1?
We can imagine our ride traveling from the starting point A to some point B (at t=1s).
We can find the angle of both points, and when we subtract them we get angular displacement.
 $A: \theta(0)=a\\
B: \theta(1)=a+b(1)^2-c(1)^3=a+b-c$
Our angular displacement is:
 $\Delta\theta=\theta(1)-\theta(0)=a+b-c-a=b-c=0.85-0.035=0.815 rad$

G(r) = -1-77 g(6) =

telo118 [61]

Answer:

g(6)= -13

Step-by-step explanation:

g(6)=−1−77

Step 1: Simplify both sides of the equation.

g(6)=−1−77

6g=−1+−77

6g=(−1+−77) (Combine Like Terms)

6g=−78

Step 2: Divide both sides by 6.

6g/6 = −78/6

g=−13
