A hot-air balloon descended 0.8 meters per second for 10 seconds. It
then climbed at 0.4 meters per second for 5 seconds.
What was the average rate of change in altitude per second?
Answer:
Step-by-step explanation:
we will use 0,8 in 10 seconds as thats the easiest.
for 10 to become 1 we move the decimel once to the right, 10/10
same will happen to 0.8,
10/10=1
0.8/10=0.08
The hot air-ballon climbs 0,08 meters per second
Can someone pls help me out
Answer:
B
Step-by-step explanation:
They aren't similar
196/70=2.8
140/49=2.85714285714 (or 2.9)
50 = -1/3b + 20
what is b?
To find b, start by subtracting 20 from both sides:
50 = -1/3b + 20
-20 -20
30 = -1/3b
Now isolate b by dividing both sides by -1/3:
30/(-1/3) = (-1/3b)/(-1/3)
-90 = b
b is 90!
hope this helps !!
please help! Complete the function for this graph.
Answer:
y = - 2|x - (-2)| + 1
Step-by-step explanation:
The general form of an absolute value function is y = a|x – h| + k, where a ≠ 0.
The value of a determines whether the graph opens up or down. If a is negative, the graph opens down. This holds true, as the value of a = -2
The given graph for the absolute function has a vertex (h, k) of (-2, 1). This is the maximum point of the graph.
Therefore, the missing values on the given equation is the value of the vertex. It has to be written as y = - 2|x - (-2)| + 1 because the equation on your given problem is formatted according to the general form of the absolute value function, y = a|x – h| + k.

5. What is the product?

a. −108
b. −81
c. 81
d. 108
Answer:
1. d 2. a 3. d 4. a 5. a
Step-by-step explanation:
For 1, d is negative because, if there an even number of negatives, the answer will be positive. a. would have been correct, but you multiply that one by 0. 0 is not negative, so the answer has to be d.
2. is -21. You can multiply 3 times seven then make it negative, or simply add -7 together 3 times.
3. is d because the two negatives cancel each other out. Even numbers of negatives cancel each other out. therefore, 17 times 6 is 102.
4. -120 is the answer because there are 3 negatives. That is an odd number, so we know our answer is negative. -5 times -3 is 15, and 15 times -8 is -120.
5. is a because -1 times 4 is -4, then -4 times -9 is 36. 36 times -3 is then -108.

what is the value of x?
Answer:
x=18
Step-by-step explanation:
the sum of all the angles in a triangle is 180 degrees.
we can use this to get an equation:
5x-6 + 3x+13 + 2x-7 = 180
combine the x's to get:
10x-6-7+13=180
combine the numbers to get:
10x=180
divide both sides by 10 to get your answer:
x=18

What is the slope of a line that is perpendicular to the line y = -1/2x + 5
To find the slope of a line perpendicular to another line, we simply need to find the inverse negative of the slope of the first one. This makes sense if you visualize it on a graph or in your head.
The slope of the line given is -1/2.
To find the inverse negative we first inverse the number, then take then negatuve of that (or opposite order).
The inverse of -1/2 is, -2 (switch the numerator and denominator or do to the power of -1, ^-1).
The negative of -2 is, 2.
Therefore the slope of the line perpendicular to y = -1/2x + 5 is 2.

Hamish buvs a new car for $20000
The car depreciates in value by 19% each year.
Work out the value of the car at the end of 3 years.
Give your answer to the nearest $
Answer:
The correct answer is $10,629
Step-by-step explanation:
Here is how I got it!
First, you will have to borrow the 20,000 from the word problem.
Next, multiply 20,000 with 0.81 with the power of 3
[tex]20,000*0.81^3=n[/tex]
The 3 is the number of years, n is the nearest $ answer.
--
First, do [tex]0.81^3[/tex]
[tex]0.81*0.81*0.81=0.531441[/tex]
(Wow, that's a crazy number!)
--
With 0.531441, multiply it with 20,000
[tex]20,000*0.531441=10628.82[/tex]
10,628.82 is technically (in money) $10,628.82 (with .82 being eighty-two cents).
--
Finally, it states to answer to the nearest $.
Just round up the .82 to 1 dollar which will just add one more dollar to 10,628
[tex]10,628[/tex] ⇒ [tex]10,629[/tex]
Add you $ symbol
With the result being: $10,629
Answer:
$10629
Step-by-step explanation:
First you have to work otu the percentage decrease:
100 - 19 = 81
81/100 = 0.81 (/ means divide)
Then you have to work the amount after 3 years:
Long Method
20000 x 0.81 = 16200
16200 x 0.81 = 13122
13122 x 0.81 = 10628.82
or Short Method
20000 x 0.81³ = 10628.82
Finally you round it to the nearest $:
10628.82 ⇒ 10629

A list of numbers is made with the pattern: Start with 3, and multiply by 2 each time.
Here is the beginning of the list of numbers: 3, 6, 12, . . .
Explain how you could use "fill down" in a spreadsheet to find the tenth number in this list.
Step-by-step explanation:
A1 3
A2 =A1*2
this A2 cell we just fill down at least to the 10th line to A10.
A10 then will display the 10th number of the list.
overall, we can see that the 10th number must be
3×2⁹
as the first number is just a constant (the starting value), and each of all the other 9 numbers are multiplying by 2.
(a + b + 1)2
– (a + b + 1)(x - 2) + (a + b + 1)
Answer: 5a + 5b + 5 - x(a + b)
Step-by-step explanation:
(a + b + 1)2 – (a + b + 1)(x - 2) + (a + b + 1)
2a + 2b + 2 - (ax - 2a + bx -2b -2) + (a + b + 1)
2a + 2b + 2 - ax + 2a - bx +2b +2 + a + b + 1
