Answer:
F(2, 11/2)
Step-by-step explanation:
The expression:
(x-2)² = 10(y - 3)
can be rewritten in the vertex form as follows:
(x-2)² = 10y - 30
(x-2)² + 30 = 10y
1/10(x-2)² + 3 = y
General vertex form is:
y = a(x-h)² + k
then, the vertex is locate at (h, k). In this case the vertes is (2, 3), and <em>a </em>= 1/10
The focus of a parabola is located ar F(h, k+p), where <em>p</em> = 1/(4a). Replacing into these equations:
p = 1/(4*1/10) = 5/2
F(2, 3+5/2) = F(2, 11/2)
8·7=56⇒8=57
7·6=42⇒7=42
6·5=30⇒6=30
5·4=20⇒5=20
4·3=12⇒4=12
<em><u>3·2=6⇒3=6</u></em>
In this question, there are 10 digit phone number which was divided into 3-3-4 digits. Every first digit of the division should be 2-9 which mean only 8 possibilities. The other digits would be 0-9 which mean 10 possibilities. Then the calculation would be:
8*10*10 * 8*10*10 * 8*10*10*10 = 8^3 * 10*7= 512 * 10^7= 5.12 * 10^9
If you convert <span>400,000,000 into the scientific form it will become 4* 10^8. Since 5.12*10^9 > 4 * 10^8, then it is clear that the number should be enough</span>
Well a chicken has 2 legs so do 2 times however many chickens there are to get the total of chicken legs. a pig has 4 legs so do 4 times however many pigs there are to get the total of pig legs. once u have those answers, do the total of pig legs plus the total of chicken legs to get your total of legs. for the number of heads, do the number of chickens plus the number of pigs.
Answer:
D. 6^-4 * 6^2
Step-by-step explanation:
= 6^-4 * 6^2
= 6 ^-2
= 1/6^2
= 1/36
