Choose the correct simplification of the expression 3 times b all over a to the power of negative 2.

MAXImum [283]

Answer:

Step-by-step explanation:

The question will look like (3b)/(a^-2)

To simplify, note the (a^-2). It is a negative, so flip the placement of the monomial. Note that the term is located in the decimal, so when it is flipped, it goes to the numerator (vice versa if it is opposite)

(3b)/(a^-2) = (3b)(a²)

3a²b, or (A) is your answer choice

Explain and Show the equation of line perpendicular to y=-1x+2 going through the point (6, 3)

valentinak56 [21]

Answer:

y = x-3 is the equation

Step-by-step explanation:

If two lines are perpendicular, the product of their slopes is -1

The general equation form of a straight line is;

y = mx + b

Fro the equation;

y = -1x + 2

The slope is -1

So the equation of the perpendicular line is as follows;

-1 * m = -1

m = 1

so we can use the point-slope equation form

That would be:

y-y1 = m(x-x1)

y-3 = 1(x-6)

y-3 = x-6

y = x-6+3

y = x-3

Natasha spent 1\dfrac121 2 1 1, start fraction, 1, divided by, 2, end fraction hours on the beach. She fell asleep for \dfrac3

Oksana_A [137]

Answer:

1 and 1/8 hours or

Step-by-step explanation:

Natasha spent one and a half hours on the beach, which can be rewritten as 3/2 hours. Out of that time, she spent 3/4 sleeping. The total time she spent sleeping on the beach is determined by the product of the amount of time she spent on the beach by the fraction of that time she spent asleep:

$T=\frac{3}{2} * \frac{3}{4}\\T=\frac{9}{8} \\T=1 + \frac{1}{8}$
