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

A bird weighs 10 N and is standing 3 m up whats its GPE
Answers
Answer:
30 J
Step-by-step explanation:
Given : -
Height ( h ) = 3m
Weight ( W ) = 10 N
To find : GPE = ?
Note : -
GPE is Gravitational Potential Energy.
It is expressed in Joules ( J ).
Formula : -
W = mg
mg = 10 N
Formula : -
GPE = mgh
GPE = 10 x 3
GPE = 30 J
Therefore,
A bird weighs 10 N and is standing 3 m, it's
GPE is 30 J.
Answer:
The answer is GPE = 300 Nm (Newton meters)
Step-by-step explanation:
The bird's mass weighs to 10 Newtons.
Presuming this took place on Earth, the gravitational force is 10 Newtons.
The bird is standing 3 meters above the ground.
Using the GPE formula (GPE = mgw,) the answer should be 300 Newton metres.

Answers
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.

[tex]2036.75088022^{2}[/tex] or [tex]2036.8^{2}[/tex] rounded to the nearest tenth
Step-by-step explanation:
1. Find the area of the base and the top, which are circles.
Area of circle : [tex]\pi 10^{2}[/tex] = 986.960440109
There are 2 circles, soooooo....= 986.960440109 x 2 = 1973.92088022
2. Find the rest of the area of the cylander.
So, we have to find the circumference of the circle.
Circumference :2[tex]\pi[/tex]10 = 62.83
3. Multiply circumference by height.
62.83 x 7 = 439.81
4. Add all of the products.
439.81 + 1973.92088022 = [tex]2036.75088022^{2}[/tex] or [tex]2036.8^{2}[/tex] rounded to the nearest tenth

Answers
The rate of change of function 1 is 0 and the rate of change of function 2 is 2. The rate of change of function 2 is 2 more than the rate of change of function 1.
Step-by-step explanation:The rate of change is also known as slope. The slope of a linear function or a line is
It is given that the function 1 is passing through the points (0,3) and (4,3). Slope of function 1 is
Therefore the slope of first function is 0.
The slope intercept form of a line is
Where, m is the slope and b is y-intercept.
The second function is
Therefore the slope of second function is 2 and the y-intercept is 1.
The rate of change of function 1 is 0 and the rate of change of function 2 is 2. The rate of change of function 2 is 2 more than the rate of change of function 1.

Answers
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.

1. ANY point on the line
2. Slope (m)
3. Y-intercept (b)
Once you have these two pieces of information, you plug the x and y values from your point and the slope (m) value into the slope-intercept form, y = mx + b.
Start by solving for the slope of each line. We need two ordered pairs (x, y) from each line to solve for the slope:
Offer A:
(0, 400) and (80, 700)
Let (x1, y1) = (0, 400)
(x2, y2) = (80,700)
m = (y2 - y1)/(x2 - x1)
m = (700 – 400)/(80 – 0) = 300/80 = 15/4
Therefore, the slope (m) for Offer A = 15/4
Next, we need the y-intercept. The y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0. One of the points we used for solving the slope for Offer A reflects the description for the y-intercept, which is point (0, 400). The y-coordinate is 400–this is the y-intercept of the line.
Now, we can establish the linear equation for Offer A: y = 15/4x + 400
Do the same steps for the other offer:
Offer B:
(0, 500)) and (100,900)
Let (x1, y1) = (0, 500)
(x2, y2) = (100,900)
m = (y2 - y1)/(x2 - x1)
m = (900 - 500)/(100 – 0) = 400/100 = 4
Therefore, the slope for Offer B is 4.
Next, we need the y-intercept. For Offer B, the line crosses at point (0, 500). The y-coordinate, 500 is the y-intercept (b) of the line.
The linear equation for Offer B is:
y = 4x + 500
**NOTE: please double-check the coordinates that I used for solving the slopes of each line before using my inputs. I had a slight difficulty going through the coordinates of your graph because it’s a bit blurry (using my phone to write this post).

Two students, Galen and Mai, worked on a project.
Galen worked for 3 2/3 hours.
Mai worked for 2 4/5 hours.
What was the total time spent on the project?
How much more time did Galen spend on the project than Mai?
Answers
Answer:
Mia worked 4/5 of an hour less than Galen.
or
Galen spent 4/5 of an hour more working on the project.
Step-by-step explanation:
First we have to find the LCM (Lowest Common Multiple) of 5 and 3 -
3: 3, 6, 9, 15, 18, 21, 24, 27, 30
5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50
We can see here, that the lowest common multiple is 15.
Now we need to convert the 2/3 and 4/5 into fractions that are equivalent to something fraction that has the denominator of 15.
2/3x5= 10/15
4/5x3= 12/15
So, now, the hours of work time of both Galen and Mia are having the same denominator, now, we can subtract.
3 10/15 - 2 12/15 = 12/15
Now, we understand that 12/15 was the amount of time Galen worked more than Mai. But, still, there is still more to do.
Suspense......
SIMPLIFY!!!
12/15 both come in 3's multiplication table.
12/15 divided by 3 = 4/5
Now, our final answer simplified is 4/5.

50 = -1/3b + 20
what is b?
Answers
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!

What is the slope of a line that is perpendicular to the line y = -1/2x + 5
Answers
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.
