Answer:
2.83 for log2(x)
15.81 for log(2x)
Step-by-step explanation:
We can get the log function by itself by subtracting the constant and dividing by the coefficient.
5 +6·log2x = 14
6·log2x = 9 . . . . . . . subtract 5
log2x = 1.5 . . . . . . . divide by 6
At this point, we're not sure what is meant by log2x.
log₂(x) = 1.5 ⇒ x = 2^1.5 ≈ 2.83
log(2x) = 1.5 ⇒ x = (10^1.5)/2 ≈ 15.81

What is composed of several food chains in an ecosystem that intersect and depend on one another?
Mnenie [13.5K]

Answer:

Food web

Step-by-step explanation:

Food chain describes how each living organism feed.

Plants are producers because the use photosynthesis to grow and provide nutrients which animals later come to consume, because animals devour plants or animals because they cannot produce their own food like plants. The animals are known as consumers.

Fungi is also a consumer because it absorbs the nutrients available from other living organisms.

Consumers are classified into three types:

1. Carnivores are organisms that feed mainly on animals



2. Herbivores who feed on plants

3. Omnivores who feed on both plants and animals.

A food web describes the relationship between various food chains and how they interact with each other in the eco system.

How far does a bus travel in 2.5 hours at 65 mph? 26 miles 135 miles 162.5 miles
sashaice [31]

Answer:

Bus travel in 2.5 hour = 162.5 miles .

Step-by-step explanation:

Given : a bus travel at 65 mph.

To find : How far does a bus travel in 2.5 hours.

Solution : We have given

Speed of bus = 65 miles per hour.

Bus travel in 1 hour = 65 miles.

Bus travel in 2.5 hour = 2.5 * 65 miles .

Bus travel in 2.5 hour = 162.5 miles .

Therefore, Bus travel in 2.5 hour = 162.5 miles .

A tower is 200 ft tall to the nearest degree find the angle of elevation from a point of 50 feet from the base of the tower to t
Elodia [21]

Answer:

Step-by-step explanation:

What you have here is classic right triangle trig.  The height of the tower is the height of a right triangle, and the point 50 feet from the base of the tower is the base of the triangle.  The angle of elevation is the base angle that is NOT the right angle.  The height is opposite the base angle, while the base is adjacent to the angle, so we need the tangent ratio to find the angle.  Here's what we have:

tan(\theta)=\frac{200}{50}

When you are looking for a missing angle, you use the inverse of the angle on your calculator.  To do this, hit the 2nd button, then tan, and what you see on your screen is

tan^{-1}(

Enter 200/50 (or 4) and hit "enter" to find the missing angle.  It comes out to 75.9 so 76 degrees.
