Angles ∝ and β are the two acute angles in a right triangle. Use the relationship between sine and cosine to find the value of β

arlik [135]

Ok so cos(x) = sin(90-x) so using that you can get sin(7x-15) = sin(90-(3x+5)) so 7x-15 = -3x+85. 10x = 100 and x = 10. Use that to find the 2 angles are 55 and 35

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 $=\frac{f(b)-f(a)}{b-a}$

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