Answer:
A:{(7,9),(13,6),(3,9),(11,-4),(1,7)}. inverse={(9,7),(6,13)(9,3),(-4,11),(7,1)}
B:{(11,8),(5,6),(3,7),(21,2),(2,5)} inverse={(8,11),(6,5)(7,3),(2,21),(5,2)}
63 degrees
Step-by-step explanation:
180 = 117 = 63
54 m
Alrighty, what have we here: an area of 162 m² and a width of 9m.
So: A=162m², W=9m, let's draw this: (see the screenshot attached)
Using the formula for area (Area = width x length) we see that:
Thus: (equating to L by dividing both sides by 9m)
⇒
Now we have all of our dimensions, we can use the formula for the perimeter to calculate it:
And there we have our answer.
7 quarters are spent for throwing 350 food pebbles in pond.
Given:
Reggie receives 50 food pebbles for every quarter he spends.
Number of food pebbles he has = 350
Let the number of quarters spent for 350 pebbles be 'x'.
Now, using proportion and cross multiplication method, we can find 'x'.
<u><em>1 quarter is equivalent to 50 pebbles thrown in pond.</em></u>
<u><em>So, 'x' quarters is equivalent to 350 pebbles thrown in pond.</em></u>
So, 7 quarters are spent for throwing 350 food pebbles in pond.

The average rate of change of f(x) in the closed interval [ a, b ] is
Here [a, b ] = [ - 5, 2 ], thus
f(b) = f(2) = 2² - 6(2) + 2 = 4 - 12 + 2 = - 6
f(a) = f(- 5) = (- 5)² - 6(- 5) + 2 = 25 + 30 + 2 = 57 , thus
average rate of change = = = - 9
