27. Suppose the hare runs 600 inches per second and the tortoise runs

Mathematics

klemol [59]3 years ago
3 0

Answer:

A. 3t = 600t + 12,000

Step-by-step explanation:

It would be A because if the tortoise is going 3 inches per second then that would be your ending point and since the hare is going 600 inches per second then you would have to add 12,000 to 600t because the tortoise is 12,000 inches in front of the hare.

at noon joice drove to the lake at 30 mi. per hour, but she made a long walk back at 4 mi. per hour. how long did she walk ifshe
Kryger [21]
Distance = 30 mph * time
distance = 4 mph * time

distance = 30 mph * t
distance = 4 mph * (17-t)

Since distance is equal then
30 mph * t = 4 mph * (17-t)
 
30t = -4t + 68

34t = 68

t = 2 hours

We see the return trip time is (17 -t ) which is 15 hours.
The beginning trip time is 2 hours.

Double Check
Beginning trip = 30 miles * 2 = 60 miles
Return trip = 4 miles * 15 = 60 miles.

3x-2y=-39 and x+3y=31 solution using elimination
Kobotan [32]
This is hard to write... I hope this makes sense to you...
3x-2y=-39
x+3y= 31
We want to use elimination therefor, we need to either get our x or our y to add together to get zero. 
To do this, we will multiply -3 to (x=3y=31) 
NEW EQUATION
3x-2y=-39 PLUS
-3x-9y= -93 Equals
Answer: -11y= -54 
y= 4.9
Plug in to solve for x (put new y in)
3x-2(4.9)=-39
x= -9.73

What is the value of the discriminant for the quadratic equation –3 = –x2 + 2x?
iogann1982 [59]

The value of the discriminant for the quadratic equation –3 = –x2 + 2x is  16

<h3>What is the value of the discriminant for the quadratic equation?</h3>

The quadratic equation is given as:

–3 = –x^2 + 2x

Rewrite the equation as:

x^2 - 2x - 3 = 0

A quadratic equation is represented as;

ax^2 + bx + c = 0

So, we have

a = 1

b = -2

c = -3

The discriminant is

d = b^2 - 4ac

So, we have

d = (-2)^2 - 4 * 1 * -3

Evaluate

d = 16

Hence, the value of the discriminant for the quadratic equation –3 = –x2 + 2x is  16
