10. If one root of the quadratic equation 2x² + kx - 6 = 0 is 2, then value of k is:

-1

Mathematics KUET MCA 2022 REPORT

Correct Answer : B
Explanation :

Given: One root of 2x² + kx – 6 = 0 is 2

Then At x = 2, the equation will be satisfied.

2 (2)² + k × 2 – 6 = 0

8 + 2 k – 6 = 0

2 k + 2 = 0

K = –1

So now the equation becomes 2x² + 2x – 6 = 0

For this equation, Product of the roots = (–6/2)

Product of roots = – 3

Let a and b be the roots of the equation and it is given that a = 2

2 × b = –3

B = –3/2

Hence the value of k = –1 and other root is –3/2.

b = a + c

2b = a + c

b² = a + c

2b² = a + c

Correct Answer : B
Explanation :

When $a, b, c$ are in A.P.,
First term is $t_{1} = a$ Second term $t_{2} = a + d = b$ third term is $t_{3} = a + 2 d = c$ Now $a + c = a + (a + 2 d) = 2 a + 2 d = 2 (a + d) = 2 b$

$\Rightarrow a + c = 2 b$

21. Given y = 5e3x+ sinx, dydx is

5e³ˣ + cos x

15e³ˣ + cos x

15e³ˣ - cos x

5e³ˣ + sin x

Mathematics KUET MCA 2022 REPORT

Correct Answer : B
Explanation :

y = 5e^3x + sin(x)
First, to find the derivative, dydx of an exponential function, we use this general form:

ae^nx = a* dydx(nx)e^nx = a*ne^nx

dydx of sin(x) = cos(x)

Applying this to the question we have:

dydx = 5* dydx(3x)e^3x + cos(x)

And,

dydx(3x) = 3

Therefore,

dydx = 15e^3x + cos(x)
