Answer:
upper bound = 112.5
lower bound = 111.5
Step-by-step explanation:
x = 360 - 59 - 108 - 81
x = 112°
upper bound = 112.5 < 113
lower bound = 111.5 < 112
so

Answer:
{ -2 if x ∈ -4 < x < -3
{ -5 if x ∈ -3 ≤ x < 2
[ 5 if x ∈ 2 ≤ x < 5
Step-by-step explanation:
From the graph, we have;

For the next inequality line at y = -5, we have;
1) The inequality line, starts with an open circle on the left at x = -3, which is equivalent to less than or equal to symbol, ≤ as -3 ≤ x because the point x =-3 is the left boundary. The inequality line extends to the point x = 2, where we have a closed circle (on the right), which is equivalent to a x ≤ 2 with the 2 on the right hand side because, the 2 is the right boundary of the inequality
2) The inequality can be summarized as starting from x = -3 extends to x = 2
3) As stated in point 1) the point x = 3, we have -3 ≤ x and at point x = 2, we have x ≤ 3 which can be combined as -3 ≤ x < 2, to give;
{ -5 if x ∈ -3 ≤ x < 2

The inequality line extends to the right to reach point x = 5, where we have a closed circle (on the right), which is equivalent to a x ≤ 5 inequality, with the 5 on the right hand side because, the 5 is the right boundary of the inequality
2) The inequality can be summarized as starting from x = 2 extends to x = 5
3) As stated in point 1) the point x = 2, we have 2 ≤ x and at point x = 5, we have x ≤ 5 which can be combined as 2 ≤ x < 5, to give;

Answer:
1st box = [-4, -3]
2nd box = (-3, 2]
3rd box = (2, 5]
For f(x) = -2 we see that x is between -4 to -3 with closed endpoints.
So the interval will be [-4, -3].
For f(x) = -5 we see that x is between -3 to 2 with closed endpoint at 2 and open endpoints at -3.
So the interval will be (-3, 2].
For f(x) = 5 we see that x is between 2 to 5 with open endpoint at 2 and closed endpoint at 5.
So the interval will be (2, 5].

Three copies of this rectangle were connected along a side to make a larger rectangle. What could the perimeter of the new rectangle be? Consider all possibilities.
Answer:
388in or 202in
Step-by-step explanation:
I decided to connect three copies of this rectangle, all along the right side of the rectangle in the picture above.
When this is done the new length along the bottom and top become 45×4=180.
Now to find the perimeter, 180+180+14+14=388in
Other possibility
Connect the three copies along the top.
Now we need to do 14×4=56, which is the new side length.
Now to find the perimeter, 56+56+45+45=202in

A seagull is floating on the surface of the ocean when it takes off and flies upward at a rate of 4 ft per second. After 19 seconds, how far away from the surface of the water will the seagull be?
Answer:
d = 76 m
Step-by-step explanation:
It is given that, the speed of 4 ft per second when it takes off and flies upward
We need to find how far away from the surface of the water will the seagull be after 9 seconds.
Speed is distance over time.
So,
Distance, d = vt
d=4 ft/s × 19 s
d=76 meters
So, the seagull will be at a distance of 76 m from the surface of water.

If 5y + 2 = 8/3, what is the value of 5y - 6?
Answer:
5y - 6 = (-16)/3
Step-by-step explanation:
1. Step:
Solve for y:
5 y + 2 = 8/3
Subtract 2 from both sides:
5 y + (2 - 2) = 8/3 - 2
2 - 2 = 0:
5 y = 8/3 - 2
Put 8/3 - 2 over the common denominator 3. 8/3 - 2 = 8/3 + (3 (-2))/3:
5 y = 8/3 - (2×3)/3
3 (-2) = -6:
5 y = 8/3 + (-6)/3
8/3 - 6/3 = (8 - 6)/3:
5 y = (8 - 6)/3
8 - 6 = 2:
5 y = 2/3
Divide both sides by 5:
y = (2/5)/3
3×5 = 15:
Answer: y = 2/15
2. Step.
Evaluate 5 y - 6 where y = 2/15:
5 y - 6 = 5×2/15 - 6
5×2/15 = (5×2)/15:
(5×2)/15 - 6
5/15 = 5/(5×3) = 1/3:
2/3 - 6
Put 2/3 - 6 over the common denominator 3. 2/3 - 6 = 2/3 + (3 (-6))/3:
2/3 - (6×3)/3
3 (-6) = -18:
2/3 + (-18)/3
2/3 - 18/3 = (2 - 18)/3:
(2 - 18)/3
2 - 18 = -(18 - 2):
(-(18 - 2))/3

Can u guys PLEASE answer this question ASAP. A fat cat that was initially 12 kg reduces its weight by 10% each month. How long does it take for the cat to be at least 6 kg lighter than its original weight? Give your answer as a whole number of months.
Answer:
It takes at least 7 months for the cat to be at least 6 kg lighter than the original weight.
Step-by-step explanation:
Use exponential decay formula:
A = P (1-r)t
A = amount decreased to
P = original amount
r = rate of decrease
t = time
6 ≥ 12 (1-0.10)t divide both sides by 12
0.5 ≥ (0.9)t take log of both sides
log (0.5) ≥ log (0.9)t power rule of logs lets the exponent t drop to front of log to become a factor
log (0.5) ≥ t log(0.9) divide both sides by log(0.9) which is negative so reverse the inequality sign
log (0.5) / log (0.9) ≤ t use calculator
6.57 ≤ t
It takes at least 7 months for the cat to be at least 6 kg lighter that original weight.
check:
12 (0.9)7≈ 5.73
12 (0.9)6 ≈ 6.37
