The polynomial is not factorable, so we use the quadratic formula.
x^2 + 5x − 2 = 0
Answer: 32°
Step-by-step explanation:
m∠BAC = m∠CDE, therefore m∠CDE = 32°

x(x-3)-2(x-3)
Solution:
(x-2)(x-3)</span>
The volume of the cone is
one-third of the volume of the cylinder which is equal to the product of area
of the base and the height. The equation is,
<span> V = (1/3)(pi)(r^2)h </span>
Dividing both sides of the
equation by (1/3)(pi)(h) will give us,
<span> 3V/(pi)(h) = r^2</span>
Taking the square-root of
both sides,
<span> r = sqrt(3V/(pi)(h))</span>
Answer:
13 participants.
Step-by-step explanation:
Given that a researcher reports an F-ratio with df = 1, 24 for an independent-measures experiment.
i.e. degrees of treatment between groups =1
and within groups = 24
This implies that there are two groups.
For two groups to have same number of participants, since we get total of degrees of freedom =24+1 =25
Hence total items selected = 26
i.e. each group would have 13 entries
So each treatment had 13 participants.
