Answer:
7/4
Step-by-step explanation:
To find the reciprocal of 4/7, flip the fraction.
The numerator goes in the denominator and the denominator goes in the numerator
7/4
To prove that tan(u - v) does not equal tan u - tan v, we start by assuming values for u and v.
To do this, we assume the following values
So, we have:
Substitute the assumed values for u and v
Subtract 45 from 75
Using a calculator, calculate the values of tan(30), tan(45) and tan(75)
So, we have:
Subtract 1 from 3.7321
Notice that the expression on the left-hand side and the expression on the right-hand side are not equal.
Hence, is true

IF THIS IS FOR 40 WHAT IS IT FOR 80

For maximum area, you've got a square. So 10 x 10. Proof 2x + 2y = 40 x + y = 20 Max xy =Max x(20-x) = Max 20x - x^2 Take 1st derivative and set to zero 20 - 2x = 0 2x = 20 x = 10 So y = 10</span>

Answer:
B) 2.3 miles
Step-by-step explanation:
This is a circle so in geometry we know a bit of formulas for this shape.
In this case we're calculating part of the perimeter of this circle.
From Ranger Station to Petting Zoo.
It tells us that the radius of this circle is 1 mile.
So perimeter of circle is: 6.28
Formula: 2πr
Now we need to find the fraction of the perimeter we're solving for: They state the sector of the circle's degree is 90+40=130 degrees.
So 130 degrees divided by 360 degrees. is 13/36. Now we can multiply 13/36 by 6.28, we get 2.26, which is 2.3 rounded to the nearest tenth.
Of course we also need to use our units miles, so 2.3 miles.
Hope this helps!
