Please help with this question ​

Mathematics

We know that \sin(45)=\cos(45) and this is the only point when sin and cos are equal lengths. Because both \sin(45),\cos(45)=\dfrac{\sqrt{2}}{2}

Now if the sin of 30° is a half that would mean that cos of 60° is also a half.

Hope this helps.

Lera25 [3.4K]

Given:

The price of bananas can be determined by the equation P=0.25n, where P is the price and n is the number of bananas.

To find:

The constant of proportionality

Solution:

We have,

P=0.25n       ...(i)

where P is the price and n is the number of bananas.

Price P is directly proportional to the number of bananas. So,

P\propto n

P=kn            ...(ii)

Where, k is the constant of proportionality.

On comparing (i) and (ii), we get

k=0.25

Therefore, the constant of proportionality is 0.25.

Lisa [10]
Comment
There are 12 months in a year. He plans on visiting 8 times each month. 

Step One 
Find the number of visits per year.

<em>Givens</em>
Number of visits per month = 8
Number of months per year = 12

Visits = # visits / month * number of months
Visitis = 8 * 12
Visits = 96 visits in total.

Step Two
<em>Calculate the cost / visit</em>
Total Cost = 414 visits.
Total Visits = 96

Cost / Visit = Total Cost / Total visits.
Cost / Visit = 414 / 96
Cost / Visit = 4.31 roughly.
