Mathematics
1 answer:
Elanso [62]3 years ago
8 0

Answer:

  a) domain: (0, ∞)

  b) range: (-∞, ∞)

  c) increasing everywhere

  d) concave downward

Step-by-step explanation:

a) Your knowledge of the log function tells you it is defined for positive arguments. 9x > 0 means x > 0. The domain is all positive real numbers.

__

b) Your knowledge of the log function tells you it has output values ranging from -∞ to +∞. The range is all real numbers.

__

c) The function is monotonically increasing.

__

d) Since the output does not increase as fast as the input (the first derivative is decreasing), the function is concave downward.

What is the length of the diagonal of the triangle?
Setler79 [48]

Answer:

21.25

Step-by-step explanation:

use the Pythagorean theorem, it is given that the shape is a rectangle so all opposite sides are congruent and all angles are right, since we know that the diagonal forms a right triangle we can use the pythagorean theorem

the Pythagorean theorm is a^2+b^2=c^2 where a and b are the legs (in this case the side of the triangle) and c is the hypotenuse which is the longest side in a right triangle

17^2+12.75^2=x^2

x^2=7225/16

now take the square root of both sides and you get -21.25 and 21.25

distance CAN NOT be negative so -21.25 isn't an option

Suppose that you need to build as many chairs as possible. Each chair requires one seat, one back, and four legs. If you have 12
GrogVix [38]

Answer:

  legs limit the number of chairs that can be built

Step-by-step explanation:

The maximum number of chairs that can be built will be the minimum of the number of parts divided by the number of parts needed for each chair, as computed across the different kinds of parts required.

  seats: 12 available, used 1 per chair: 12/1 = 12 chairs possible

  backs: 15 available, used 1 per chair: 15/1 = 15 chairs possible

  legs: 44 available, used 4 per chair: 44/4 = 11 chairs possible

The maximum number of chairs that can be built will be the minimum of 12, 15, and 11. That is, 11 chairs can be built, limited by the number of available legs.
