Answer:
Step-by-step explanation:
The standard form of a circle's equation is
where h and k are the circle's center and r is the radius. We are told, and we can see, that the center of the circle is (0, 0) so h = 0 and k = 0. The radius, given as 4, goes into the equation squared, so the equation is
which simplifies down to
, choice C.
Answer:
<u><em>22 cm²</em></u>
Step-by-step explanation:
Work out the area of this triangle.
Area Formula: 1/2b * h where b = base (11cm) and h = height (4 cm)
1/2 *11 * 4 =
5.5 * 4 =
<u><em>22 cm²</em></u>
The answer is:
(v-1)(v+1)(v^2+1)
Y=30x.
Whatever the number of months is you times by 30, the amount she added each month. If she had started with a certain amount you would add that to the equation. Y is the total money in the account.
