Tan A = opposite leg/adjacent leg = a/b
Answer C: a/b
Answer:
i will say 15 and -7
Step-by-step explanation:
15+-7=8 and 15--7=22
15+-7 so take the negative and take out that mush of the big number
15-7=8
15--7= the subtracting beside a negative makes it changes to positive and addition so 15+7=22
The inner circle circumference is 18 and the outer is 4
The vertex is at (-3, 4)
This can be found by looking at the basic form of vertex form:
y = (x - h)^2 + k
In this basic form the vertex is (h, k). By looking at what is plugged into the equation, it is clear that h = -3 and k = 4. This means the vertex is at (-3, 4).
The y-intercept is at 13. To find this we must first square the parenthesis and get the equation into standard form.
y = (x + 3)^2 + 4
y = x^2 + 6x + 9 + 4
y = x^2 + 6x + 13
Now we know that the y-intercept is equal to the constant, which is the last number in the equation.
