ExplanationSubstitute x with 4 in the function: 2(4) + 3 = 8 + 3 = 11.

x^2

3x^2

2x^2

ExplanationUsing the power rule, the derivative of x^n is nx^(n-1). Thus, 3 * x^(3-1) = 3x^2.

ExplanationThe sum of interior angles is (n-2) * 180. Setting 540 = (n-2) * 180 results in n-2 = 3, so n=5.

ExplanationSince 2 raised to the power of 3 equals 8 (2^3=8), the log base 2 of 8 is 3.

ExplanationArea = πr^2. 16π = πr^2 means r=4. The diameter is 2r, which is 8.

2x3

3x2

2x2

3x3

ExplanationWhen multiplying a (m x n) matrix by an (n x p) matrix, the resulting matrix is (m x p).

ExplanationThe integral of x is (1/2)x^2. Evaluating (1/2)(2^2) - (1/2)(0^2) equals 2.

Equilateral

Isosceles

Right-angled

Obtuse

ExplanationSince 3^2 + 4^2 = 5^2 (9 + 16 = 25), it satisfies the Pythagorean theorem.

x^2

3x^2

2x^2

ExplanationUsing the power rule for derivatives (d/dx x^n = nx^{n-1}), the derivative of x^3 is 3x^2.

ExplanationPlugging x = 1 into the equation: (1)^2 - 4(1) + 3 = 1 - 4 + 3 = 0.

1/3

-3

ExplanationThe equation is in slope-intercept form (y = mx + b), where m is the slope.

0.5

undefined

ExplanationIn trigonometry, the sine of 90 degrees is exactly 1.

4π

8π

16π

64π

ExplanationThe area of a circle is calculated as πr^2. With r=4, Area = π(4^2) = 16π.

ExplanationSubtract 10 from both sides to get 2x = 10, then divide by 2 to get x = 5.

x^2

3x^2

2x^2

ExplanationUsing the power rule for derivatives, the derivative of x^n is nx^(n-1).

ExplanationSince 2 raised to the power of 3 equals 8, the log base 2 of 8 is 3.

Equilateral

Isosceles

Right-angled

Obtuse

ExplanationBecause 3 squared plus 4 squared equals 5 squared (9+16=25), it satisfies the Pythagorean theorem.

Undefined

ExplanationSimplifying the expression to (x-1)(x+1)/(x-1) leaves x+1. Plugging in 1 gives 2.

-1

ExplanationSubstituting x=1 into the equation: (1)^2 - 4(1) + 3 = 1 - 4 + 3 = 0.

ExplanationIn the slope-intercept form y = mx + c, the coefficient 'm' represents the slope (gradient). Here, m = 3.

0.5

-1

ExplanationIn a right triangle or on the unit circle, the sine of 90 degrees is equal to 1.

4π

8π

12π

16π

ExplanationThe area of a circle is calculated using π * r^2. Given r = 4, the area is π * 4^2 = 16π.

ExplanationSubtract 10 from both sides to get 2x = 10, then divide by 2 to get x = 5.

Equilateral

Isosceles

Right-angled

Obtuse

ExplanationAccording to the Pythagorean theorem, if 3^2 + 4^2 = 5^2 (9 + 16 = 25), the triangle must be right-angled.

Undefined

ExplanationFactor the numerator: (x-1)(x+1) / (x-1). The (x-1) terms cancel out, leaving x+1. As x approaches 1, 1+1 = 2.

120

240

ExplanationFactorial 5 is 5 * 4 * 3 * 2 * 1 = 120.
