Write the equation in standard form for the circle passing through ( - 2,0) centered at the origin.

1 answer:

5 0

X^2 + Y^2 = 4 This centers at origin, since h and k values are zero ( therefore nonexistent) and the radius is 2 so it goes through (-2,0)

How many 3-letter sequences can be formed if the second letter must be a vowel (A, E, I, O, or U), and the third letter must be

erica [24]

Answer:

120 ways

Step-by-step explanation:

Given that, 3-letter sequences should be formed, where the second letter must be a vowel (A, E, I, O, U) and the third letter must differ from the first letter.

There are 26 alphabets in English,

so, firstly let us fix the second letter to be one of the vowels

now we are left with 25 alphabets and now let us fix the third letter to be an alphabet from the remaining 25 alphabets.

now, we are left with 24 alphabets and the first letter can be any of these 24 alphabets.

so, there are 24 ways to fill the sequence.

The same thing can be done with the other 4 vowels.

so, total number of ways = 5 × 24 = 120 ways.

The table shows the price of two cereal brands and the number of ounces per box. Which is the better price per ounce?

Romashka-Z-Leto [24]

Answer:

A) Cereal brand A

B) There is no table.

Step-by-step explanation:

A) divide each cereal price by the amount of ounces. Brand A is $0.13888 (rounds to $0.14). B is $0.14583 (rounds to $0.15) So, since cereal band A is less cost per ounce, its cheaper

B) This question cannot be answered, since there is no table.

Diano4ka-milaya [45]

Answer:

1 and 6

Step-by-step explanation:

it is just like the roots of a polynomial, since $\sqrt{x-1}$ (x-6)^2=0

we can separate the two pieces of the problem

\sqrt{x-1} =0

square both sides to get

x-1=0. x=1

(x-6)^2=0

square root both sides and get

x-6=0

x=6

so the two inflection points of the equation are 6 and 1

Hope that helps :)
