the length in centimeters of the Panama Canal on Anas map is
.
<u>Step-by-step explanation:</u>
Here we have , Ana drew a map of the Panama Canal. In the scale Ana used for the map 4 centimeters represents 20 kilometers. The actual length of the Panama Canal is 82 kilometers. We need to find What is the length in centimeters of the Panama Canal on Anas map . Let's find out:
In the scale Ana used for the map 4 centimeters represents 20 kilometers , that means for 4 cm we have 20 km , So for 1 km we have :
⇒ 
⇒ 
⇒ 
⇒ 
Hence , for 82 km we have :
⇒ 
⇒ 
⇒ 
Therefore , the length in centimeters of the Panama Canal on Anas map is
.
Slope Formula:

I am going to show you how to do this on problem 6, and you will do the rest of the problems.
Here are the steps to solving problem 6
Step 1) Substitute the coordinates into the slope formula

Step 2) Now Lets simplify the denominator, so we don't have two Subtractions symbols.

Step 3) Simplify

Step 4) We can still simplify more

Hope This Helps ... Good Luck
[The reason I didn't do all of them is because you need to know how to do them. Trust me later on knowing these is going to be very handy.]
Answer:
Height of slide = 5 feet (Approx.)
Step-by-step explanation:
Given:
Length of slide = 12 feet
Angle of depression = 25°
Find:
Height of slide
Computation:
Length of slide = Hypotenuse
Height of slide = Perpendicular
Using trigonometry function;
Sin θ = Perpendicular / Hypotenuse
Sin 25 = Height of slide / 12
0.422 = Height of slide / 12
Height of slide = 12 x 0.422
Height of slide = 5.064
Height of slide = 5 feet (Approx.)
Answer:
a. x² + 10x + 25
Step-by-step explanation:
because
(x + 5)² = (x + 5)(x + 5) = x² + 5x + 5x + 25 = x² + 10x + 25
so, it is a perfect square of (x + 5).
