Answer:
Step-by-step explanation:
See attachment for question illustration
From the attachment, we have:
Required
Solve d
First, we need to calculate <C
--- angles in a triangle
Make <C the subject
Next, we apply Sine's law to solve for d
In this case:
Make d the subject
<em>Hence, the base of the lake is approximately 340.7m</em>
To solve this, we'll use the trigonometric function called cosine.
The cosine of an angle -in a right triangle-, is equal to the side adjacent to the angle over the hypotenuse of the triangle.
Given the angle 41, its adjacent side is
and the hypotenuse is 55, so:
We solve for
:
The answer is 41.51.

Step-by-step explanation:
Given
Required
Determine the average rate of change
This is calculated using:
Where
So, we have:
Solve for f(t) and f(1)
So, we have:
Factorize:
Apply difference of two squares
Answer:
The median is the value that's exactly in the middle of a data set when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values.

Answer:
2.625 pounds are left or 2 5/8
Step-by-step explanation:
So if your going to be subtracting a fraction from a whole number your going to have to consider the fact that the whole number can be divided up into that fraction.
So in this equation we are subtracting 2 3/8 from 5, we are going to take one from 5 and make it into a fraction so we can subtract:
5 = 4 8/8
Now we subtract 2 3/8 from 4 8/8
4 8/8 - 2 3/8 = 2 5/8
so there's your answer 2 5/8 pounds are left over, but if you wanted the answer in a decimal you would divide 5 by 8:
5/8 = 0.625
you then add 0.625 to 2:
2 + 0.625 = 2.625
And that is also your answer: 2.625 lbs. were left over.
