7.) (36+42) x 24 / 2 = 936
8.) (11+14) x 10 / 2 = 125
9.) 16 x 9 / 2 = 72
10.) 21 x 32 / 2 = 336
Answer:
? = 33
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan ? = opp / adj
tan ? = 13/20
Take the inverse tan of each side
tan ^-1 tan ? = tan ^-1 ( 13/20)
? = 33.02386756
To the nearest degree
? = 33
Answer:
3 X (2+3)
Step-by-step explanation:
If we have five students (3 girls and 2 boys), and three groups, we can use the expression 3 X (2+3), which concludes three groups times five students (in each group), which will give us our total of 15 students.
Answer:
7, -3/4, -3
Step-by-step explanation:
Note that all three of the given functions are linear. We can read the slopes directly from these functions: 7, -3/4, -3. Between any two values of x, the slope is exactly the same in each of these three functions.
Thus,
1) the average rate of change of f(x) = 7x - 4 over the interval [2,4] is 7.
2) the average rate of change of g(x) over the given interval is -3/4.
3) the average rate of change of h(x) over the given interval is -3.
