Table now shown, not enough information in this question. is this a linear function (or graph), if so:
(4,9),(6,11),(8,13),(10,15).
Answer:
-2.7 < y
Step-by-step explanation:
2.9 < 5.6+y
Subtract 5.6 from each side
2.9-5.6 < 5.6-5.6+y
-2.7 < y
Answer:
The correct option is C.
Step-by-step explanation:
The given equation is
![\frac{(x-6)^2}{16}+\frac{(y+7)^2}{4}= 1](https://tex.z-dn.net/?f=%5Cfrac%7B%28x-6%29%5E2%7D%7B16%7D%2B%5Cfrac%7B%28y%2B7%29%5E2%7D%7B4%7D%3D%201)
It can be rewritten as
.....(1)
The standard form of an ellipse is
....(2)
Where (h,k) is center of the ellipse.
If a>b, then the vertices of the ellipse are
.
From (1) and (2) we get
![h=6,k=-7,a=4,b=2](https://tex.z-dn.net/?f=h%3D6%2Ck%3D-7%2Ca%3D4%2Cb%3D2)
Since a>b, therefore the vertices of the ellipse are
![(h+a, k)=(6+4,-7)\Rightarrow (10,-7)](https://tex.z-dn.net/?f=%28h%2Ba%2C%20k%29%3D%286%2B4%2C-7%29%5CRightarrow%20%2810%2C-7%29)
![(h-a, k)=(6-4,-7)\Rightarrow (2,-7)](https://tex.z-dn.net/?f=%28h-a%2C%20k%29%3D%286-4%2C-7%29%5CRightarrow%20%282%2C-7%29)
The vertices of the given ellipse are (10, –7) and (2, –7). Therefore the correct option is C.
Answer:
0.34
Step-by-step explanation:
Percentages can be changed to decimals by dividing by 100 (or moving the decimal <u>left</u> two places).
Decimals can be changed to percentages by multiplying by 100 (or moving the decimal <u>right</u> two places).
Since 34% can be written as 34.0%, we <u>divide by 100</u> and move the decimal <u>left</u> two places so it becomes 0.34.
To find the mean and the numbers together and the divide by the amount of numbers you added.54.2
