Answer:
csc θ = (3/2)
Step-by-step explanation:
Cosecant is just the inverse of sine
Answer:
2x^4
Step-by-step explanation:
Focus has coordinates (0, a)
a = -3
Thus, 4a = 4(-3) = -12
Because a is negative, we know it will be a concave down or concave left parabola. Hence, A and D can be eliminated. And we know it has to be B because the directrix is the horizontal line y = 3. Hence, the equation of the parabola becomes:

or
Answer:
The length of cloth Geeka got is 2.32m
Step-by-step explanation:
The length Geetika got can be calculated by deducting the total length the tailor cuts from the initial length of the cloth.
Initial length of cloth = 15.40m
From the question, the tailor cuts 11m and 5cm for dress and 2m 3 cm for a shirt.
Therefore, the total length the tailor cut = 11m 5cm + 2m 3cm = 13m 8cm
NOTE: 13m 8cm = 13.08m
The length Geeka got = 15.40m - 13.08m = 2.32m
Hence, the length of cloth Geeka got is 2.32m
Before you use the quadratic formula, you have to make sure the equation itself is a quadratic and that a and b are not 0.
