Mathematics
1 answer:
Natalija [7]3 years ago
5 0

Answer:

x=3 , x=-3

Step-by-step explanation:

e^{lnx^2} -9= 0

Add 9 on both sides

e^{lnx^2}=9

To remove base 'e' we take ln on both sides

ln e^{lnx^2}=ln9

lnx^2=ln(9)

Both sides have ln , so we make the terms equal

x^2=9

Take square root on both sides

x=+-3

x=3 , x=-3

Which of the following quantities are continuous?
Oxana [17]

Answer:

A. only II

Step-by-step explanation:

Mathematics calculus differentiates things into discrete and continuous. Discrete things have indivisible units, the example will be how many dogs in a village. There is no half dog, it's either one, two, etc. But the distance covered by train can be written as half miles, it's divisible unit.  

The number of books and bracelets also discrete, thus the answer is A.

URGENT!!!! The area of a rectangular floor is 80 square feet. The length of the floor is 2 feet less than the width of the floor
KatRina [158]

Answer:

The width of the floor is 10 ft.

Step-by-step explanation:

First, you have to form expressions of width and length in terms of w. With the given information :

width = w ft

length = (w - 2) ft

Given that the area of rectange is A = length × width so you have to subtitute the expressions and value into the formula :

A = l × w

80 = (w - 2) × w

w(w - 2) = 80

w² - 2w = 80

w² - 2w - 80 = 0

(w + 8)(w - 10) = 0

w + 8 = 0

w = -8 (rejected)

w - 10 = 0

w = 10

Tina rides the bus to school, Theo bikes to school, and Tony walks to school. Their probabilities of being the first one to scho
Pie

Answer:

Tina is first

Tony is first

Theo is first

Step-by-step explanation:

Events with greater probability are more likely.

Let's put the probabilities in decimal form.

P(Tina is first) = 0.05

P(Theo is first) = %85 = 0.85

P(Tony is first) = 1/10 = 0.1

0.05 < 0.1 < 0.85

The events are listed below from least to most likely.

Tina is first, Tony is first, Theo is first

hope it helps
