Answer: 5(5 + 9). This expression can be solved by multiplying 5 by both the addends. So, 5(5) + 5(9) = 25 + 45 = 70.
Step-by-step explanation:
Answer:
It is true, because the cosine function has a period of 2π
Step-by-step explanation:
Since, the period of the cos function is 360° ( or 2π radians ), it holds the property of:
Taking as , is equal to
The equation is true!
<u>Note:</u> The cos function is even function
Hence, the equation is true, because the cosine function has a period of 2π, NOT because the cosine function is ODD, which it is not!!
The similarity ratio of STUV to CBED is 0.5
<h3>How to determine the
similarity ratio of STUV to CBED?</h3>
For the shapes to have a similarity ratio, it means that:
The shapes are similar (not necessarily congruent)
From the diagram, the following sides are corresponding sides
ST and CB
Where
ST = 2
CB = 1
The similarity ratio of STUV to CBED is calculated as:
Ratio = CB/ST
Substitute the known values in the above equation
Ratio =1/2
Evaluate
Ratio = 0.5
Hence, the similarity ratio of STUV to CBED is 0.5
