Answer:
Sperm is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction. Animals produce motile sperm with a tail known as a flagellum, which are known as spermatozoa, while some red algae and fungi produce non-motile sperm cells, known as spermatia
The correct answer is option B which is 3

What is mean?</h3>
Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.
Given data:-
4,3,2
The mean will be calculated as:-
Mean = (4 + 3 + 2) / 3
Mean = 9 / 3
Mean = 3
Therefore the correct answer is option B which is 3

Answer:
Y= 2e^(5t)
Step-by-step explanation:
Taking Laplace of the given differential equation:
s^2+3s-10=0
s^2+5s-2s-10=0
s(s+5)-2(s+5) =0
(s-2) (s+5) =0
s=2, s=-5
Hence, the general solution will be:
Y=Ae^(-2t)+ Be^(5t)………………………………(D)
Put t = 0 in equation (D)
Y (0) =A+B
2 =A+B……………………………………… (i)
Now take derivative of (D) with respect to "t", we get:
Y=-2Ae^(-2t)+5Be^(5t) ....................... (E)
Put t = 0 in equation (E) we get:
Y’ (0) = -2A+5B
10 = -2A+5B ……………………………………(ii)
2(i) + (ii) =>
2A+2B=4 .....................(iii)
-2A+5B=10 .................(iv)
Solving (iii) and (iv)
7B=14
B=2
Now put B=2 in (i)
A=2-2
A=0
By putting the values of A and B in equation (D)
Y= 2e^(5t)
Answer:
Option (B)
Step-by-step explanation:
Vertex of the given parabola → (0, 4)
Equation of the parabola with vertex (0, 4)
y = (x- 0)² + 4
y = x² + 4
Domain of this function is x < 2
Therefore, y = x² + 4 x < 2
Slope 'm' of the line passing through (4, 0) and (2, 2),
m =
=
= -1
Equation of the line passing through (4, 0) and slope 'm' = -1
y - 0 = (-1)(x - 4)
y = -x + 4
Domain : x ≥ 2
Therefore, function will be, y = -x + 4 x ≥ 2
y = x² + 4 x < 2
-x + 4 x ≥ 2
Option (B) will be the answer.
