Step by step explanation:
Answer:
Domain = for all x pertaining to reals minus x = 2 and x = -3
Step-by-step explanation:
For this expression to exist, the denominator must be different from zero, so
applying quadratic equation
x1=(-1+5)/2=2, x2=(-1-5)/2=-3 so, (x-2)(x+3)≠0
Dm=(∀ x ∈ IR - (-3 ∧ 2))
Domain = for all x pertaining to reals minus x = 2 and x = -3
= 3 hours : 45 minutes
= (3 hours)/(45 minutes)
We know, 1 hour = 60 minute, 3 hours = 3 × 60 minutes = 180
minutes,
= (180 minutes)/(45 minutes)
= 180/45
= 4/1
= 4 : 1
A fact or piece of data from a study of a large quantity of numerical data
Total amount of money received by David for working at his father's store = $50
Amount of money spent by David at the movies = $20
Amount of money spent by David buying comics books = $10
Amount of money spent by David buying candy = $5
Then
Total amount spent by David = (20 + 10 + 5) dollars
= 35 dollars
Amount of money saved by David = (50 - 35 ) dollars
= 15 dollars
So
The ratio of the amount of money David
spent to the amount of money David saved = 35:15
= 7:3
So the ratio of the amount of money David spent to the amount of money David saved is 7:3
