Answer:

cos(37°15')=0.7960

Step-by-step explanation:

Evaluate cos(37°15').

First we convert 15' into degree

60' = 1 degree, to convert 15' to degree we divide by 60

So 15' = \frac{15}{60} =0.25 degree

cos(37°15')=cos(37° +0.25°)= cos(37.25°)

Now we use calculator to find the value of cos(37.25°)

Put the calculator in degree mode

cos(37.25°)=0.7960

Ket [755]

"Since the ratio is 5:7 you can think in total there was 12 equal blocks of money invested. 5 of those blocks belonged to Jim and 7 of those blocks belonged to Gail. Since they invested $3,600 and then made $6,450 in total there is $10,050. Divide that total into 12 equal blocks of $837.50 and 5 of those blocks belong to Jim. So he will get $4,187.50"

Find the length and width of a rectangle that has the given perimeter and a maximum area. perimeter: 244 meters
MissTica
We know that

[perimeter of rectangle]=2*(<span>length+width)
</span>
Let
x-----------> length
y-----------> width
so
P=2*(x+y)-----------> 244=2*(x+y)-----> x+y=122-------> y=122-x

Area=x*y-------> x*(122-x)----> 122x-x²

find the derivative function and equals to zero

122-2x=0-----> 122=2x----------> x=61 m
y=122-x------> y=122-61---------> y=61 m

<span>the maximum area is given by a square
</span>
the answer is
is a square of side 61 m
