If sin (7y) = cos (5y + 14), find y.

Mathematics
1 answer:
Reil [10]3 years ago
7 0

Answer:

Step-by-step explanation:

sin(7y)=cos(5y+14)=sin(90-(5y+14))=sin(76-5y)

7y=76-5y

12y=76

y=76/12=19/3

or

sin(7y)=cos (5y+14)=sin (90+(5y+14))=sin (5y+104)

7y=5y+104

2y=104

y=52

What is the average rate of change of the function f(x) = 4x – 2 over the interval x = –1 and x = 2?
Alexeev081 [22]

Answer:

4

Step-by-step explanation:

Given: f(x)=4x-2

To find:  average rate of change of the function f(x)=4x-2 over the interval x=-1 and x=2

Solution:

Take a=-1,\,b=2

Find f(a),\,f(b)

f(a)=f(-1)\\=4(-1)-2\\=-4-2\\=-6\\\\f(b)=f(2)\\=4(2)-2\\=8-2\\=6

Average rate of change of the function =\frac{f(b)-f(a)}{b-a}

=\frac{f(2)-f(-1)}{2-(-1)}\\\\=\frac{6-(-6)}{3} \\\\=\frac{12}{3}\\\\=4
