Answer:
A for Circle=2pi*r and A for Square= b*h, then find the difference between the two
Step-by-step explanation:
So, let's see, the point say P, is 3/4 of the way from R to S, namely, if we split the segment RS into 4 pieces, from R to P, or RP will take 3 of those quarters, and from P to S, or PS, will take one of those quarters, check the picture below.
so the RP section is at a ratio of 3, whilst the PS section is at a ratio of 1.
and that's the y-coordinate for the point P.
Well this is pretty easy, look. First we divide 3/4 (Length of shadow), then we multiply that by 36 (4*9 = 36), then we get 27 as an answer! Hope this helped. Brainliest is always appreciated.
Step-by-step explanation:
Let √x - 1/√x = a
Squaring both the sides,
x + 1/x - 2 = a^2
Putting the value,
3–2√2 + 1/(3–2√2) - 2 = a^2
a^2 = 1 - 2√2 + 1/(3–2√2)
= [(3–2√2) (1–2√2) + 1] / 3–2√2
= {3 - 8√2 + 9} / 3–2√2
= [12 - 8√2] / 3–2√2
Rationalising both the sides
= {(12 - 8√2)(3+2√2)} ÷ (9–8)
= 36 + 24√2 - 24√2 + 16(2)
= 36 - 32
=> 4
a^2 = 4
a = √4
a = 2, -2
So,
√x - 1/√x = a = 2, -2.
Answer:
See below
Step-by-step explanation:
The Fundamental Theorem of Algebra states that the degree of the polynomial is the number of roots, where some may be complex depending on the polynomial or degree.
In this case, 2x^2-x+2=0 has its highest degree of 2, so there are 2 roots.
