Answer:
Step-by-step explanation:
a) It can be convenient to use the square root function as one being defined only for values greater than or equal to some number. Here, we need to shift that function 3 units to the left, so its domain is [-3, ∞).
__
b) One way to put holes in a function is to put vertical asymptotes there. This function can be defined to have vertical asymptotes at x=2 and x=4 so those values are excluded from the domain.
Answer:
$0.09 or 9 cents
Step-by-step explanation:
1.17/3=0.39
2.4/5=0.48
0.48-0.39=0.09
Answer: 3
Step-by-step explanation:
Factor: Trying to factor by splitting the middle term
The first term is 15a^2, its' coefficient is 15
The middle term is - 58a, its' coefficient is - 58a
The last term is "The Constant" is +48
Multiply the coefficient of the first term by the constant 15(48) = 720
Find two factors of 720, whose sum equals the coefficient of the middle term, which is -58

Factoring: 15a^2 - 58a + 48 = 0
Factor left side of equation:
(5a - 6)(3a - 8)
Set fractions equal to Zero
5a - 6 = 0 or 3a - 8 = 0
Answer : a = 6/5 = 1.200
or a = 8/3 = 2.667
Hope that helps!!!!
