I dont understand bc all of the y/x come out different. Plz help
9514 1404 393
Answer:
A. y = 0.45x +7
Step-by-step explanation:
When the y/x come out different, it means the relation is not a proportion. So, the "rate of change" need to be computed from ∆y/∆x, not y/x.
∆y is the difference between two y-values. If we use the first two columns of the table, we have ...
∆y = 6.2 -5.4 = 0.8
∆x = 3 - 1 = 2
Then the rate of change shown in the table is ∆y/∆x = 0.8/2 = 0.4.
__
For the equations, the rate of change is the coefficient of x. Those are ...
0.45, -1/2, 0.2, 1/10
If we were to put these rates of change in order on a number line, that order would be ...
-1/2 < 1/10 < 0.2 < 0.4 < 0.45
A: y = 0.45x+7 has a greater rate of change than shown in the table.

for the trapezoid/trapezium
the formula for finding the area of a trapezoid is A=(a+b)/2*h, and if you didnt know, a and b are always parallel.
for the parallelogram
it will always be b*h, this one is pretty easy to remember, also parallelograms include squares, rectangles, and anything with 4 sides.
the example
lets just say that we are missing a, which is the top one. now we have to fill in the missing little bit marked by a green square. this particular trapezoid is symmetrical, so we dont have to find the other side, but if it wasn´t, then you have to find the other side with the Pythagorean thoream. That is what we are going to do now. We have a and c and we need to find b in a²+b²=c², so plug in our values for a and c
(10)²+b²=(13)²
100+b²=169
now just isolate b and solve
b²=69
how to undo a square is by taking the square root of the other side of the equation
sqrt(69) is about 8.3

A very strong wind is blowing over some mountains. Bella, the eagle, begins to fly home to bring food to the hatchlings in the nest. For every five hundred fifty meters Bella flies, she is blown back fifty meters by the wind. Bella's nest is five kilometers away. If bella flies five hundred fifty meters in one minute and begins at eleven thirty in the morning, what time will bella reach the nest?
Answer:
11:40 in the morning
Step-by-step explanation:
Given that for every 550 m, Bella the eagle flies, she is blown back fifty meters by the wind. Her nest is 5 km and she flies 550 m in 1 minutes.
Therefore for Bella to reach her nest which is 5 km (5000 m) away, the required distance (d) she needs to travel is:
d - (d/550)50 = 5000
d - 50d/550 = 5000
500d / 550 = 5000
d = (550 * 5000) / 500 = 5500
d = 5500 m = 5.5 km
speed = distance / time = 550 m / 1 minutes = 550 meters per minute
The time t required to cover 5500 m is:
speed = distance / time
550 meters per minute = 5500 m / t
t = 5500 m / 550 meters per minute
t = 10 minutes
If Bella lives at 11:30 am in the morning and then travels for 10 minutes to reach her nest, the time Bella will reach her nest is 11:40 am

Answer:
m∠FAN = 80°
Step-by-step explanation:
Area of a sector is given by the expression,
Area of the sector = [tex]\frac{\theta}{360}\pi r^{2}[/tex]
Here, θ = central angle subtended by the arc
r = Radius of the circle
By substituting the values from the question,
288π = [tex]\frac{\theta}{360}(\pi )(36)^2[/tex]
θ = [tex]\frac{288\pi }{1296\pi }\times 360[/tex]
θ = 80°
Therefore, m∠FAN = 80° will be the answer.

Answer:
Vertex means the highest or lowest coordinate in a parabola (and also absolute value)
Here we see the lowest point is (-2,0), so the vertex is (-2,0)
A standard quadratic equation is written as a(x-h)^2+k
h and k are the vertex coordinate h is x and k is y
so by finding the vertex we found that h = -2 and k = 0
so you plug it in
a(x-(-2))^2+0=y
a(x+2)^2=y
when finding a, you take a random point in the graph and plug it in and solve it
lets take (-1,1)
so its a(-1+2)^2 = 1
a(1)^2 = 1
a=1
so the equation will be 1(x+2)^2 = y or (x+2)^2=y (don't need to write the 1)
Hope that answers your question

Answer:
1. 20 half of 20 is 10(new radius),
10^10 = 100
100 x 3.14 = 314
314 divided by 2 = 157
2. 8 x 8 = 64, 64 divided by 2 ( x 1/2) = 32
half of 8 is 4(new radius)
4 ^4 = 16, 16 x 3.14 = 50.24
50.24 divided by 2 = 25.12
25.12 + 32 = 57.12
3. Half of 7 is 3.5(new radius)
Just find the area of a full circle since two semi circles make a full circle.
3.5^2 = 12.25
12.25 x 3.14 = 38.465,
21 x 7 = 147
147 + 38.465 = 185.465
4. Half of 6 is 3(new radius)
3^3 = 9
9 x 3.14 = 28.26, 28.26 divided by 2 = 14.13
11 x 6 = 66, 66 divided by 2 (x 1/2) = 33
14.13 + 33 = 47.13
5. 81 divided by 4 = 20.25
half of 20.25 is 10.125(new radius)
10.125 x 2 x 3.14 = 63.585 rounded = 63.59

Answer:
C and D
Step-by-step explanation:
So from the equation y = 1.26x + 9.49 we can gather that 9.49 is an initial value because it has to be added to the number with a variable ( 1.26x)
Because 1.26 has a variable of x and x represents a week, we know that the number 1.26 will increases in value depending on how many weeks have passed.

The distribution peaks at 5
The distribution is symmetrical
The data set has a range of 5
The distribution is skewed to the left
Answer:
The distribution peaks at 5. This is the only right answer
Step-by-step explanation:
The distribution is NOT symmetrical- the distribution is skewed to right. If you divide the plot in half (make a vertical line going between 3 and 4 in your head) you'll that both sides are not the same
The data set has a range of 3- 5 minus 2 equals 3
The distribution is skewed to the right, not the left (most of the data is on the right side of the plot aka 4 and 5. this goes back to the distribution not being symmetrical)
Answer:
The distribution peaks at 5.
The distribution is symmetrical.
The data set has a range of 5.
