Horizontal Shrink: y = cos 2x or if the coefficient of x is greater than 1
Vertical Stretch: y = 2 cos x or if the coefficient if cos x is greater than 1
Horizontal Stretch: y = cos (1/2) x or if the coefficient of x is less than 1
Vertical Shrink: y = (1/2) cos x or the coefficient of cos x is less than 1
The base value is 1 since it is the original coefficient of x and cos x. The values would adjust depending on the original coefficients.
Answer:
where 
denote arc lengths of two circles
Step-by-step explanation:
Let denote arc lengths of two circles, 
denote corresponding radii and
denote the corresponding central angles.
So,
and 
This implies 
and 
As each circle has an arc where the measures of the corresponding central angles are the same, 
As radius of one circle is twice the radius of the other circle,
Answer: 168 toads
Step-by-step explanation:
First we need to find the area of the garden. Area = length x width
Area = 12m x 7m = 84 m²
2 toads/ 1 sq m
84(2) = 168
Answer:
The product is 240.
Step-by-step explanation:
The product is always when you multiply numbers together.
Answer
Find out the conversion factor for seconds to minutes and convert 135 seconds to minutes.
To prove
1 minute = 60 second
for seconds to minutes.
Therefore the conversion factor for seconds to minutes be
Now convert 135 seconds to minutes.
= 2.25 minutes
Hence proved
