Answer:
8 over 4
Step-by-step explanation:
For these problems you have to use PEMDAS so for problem 15 you would do the parentheses first, (21-3) you get 18 and then exponents, 3^2, you get 9, no multiplication but there is division so take your answers, 18 and 9 and divide them, you get 2, so the answer to 15 is 2.
Answer:
.
Step-by-step explanation:
If (α, β) are the coordinates of the center of the hyperbola, then its equation of the hyperbola is
.
Now, the vertices of the hyperbola are given by (α ± a, β) ≡ (1,-3) and (-3,-3)
Hence, β = - 3 and α + a = 1 and α - a = -3
Now, solving those two equations of α and a we get,
2α = - 2, ⇒ α = -1 and
a = 1 - α = 2.
Now, eccentricity of the hyperbola is given by
{Since
given}
Therefore, the equation of the given hyperbola will be
. (Answer)
Answer:
Opt A and D
Step-by-step explanation:
65% is 100 based number, this means that 65% is the same as 65/100, or 0,65.
65% of 20 is obtained performing the following operation:
0,65 * 20
or
65*20/100
Any of them
Answer:
50 square units
Step-by-step explanation:
