Answer:

The found angle D is:

D = 51.7°

Step-by-step explanation:

We have a right angle triangle with the right angle at F.

The given right angle triangle is shown in the diagram below.

EF = 95ft ⇒ Perpendicular of the triangle

FD = 75 ft ⇒ Base of the triangle

We have to find angle D.

Lets find angle D by using tan.

We know that

tan D = Perpendicular of the triangle / Base of the triangle

tan D = 95/75

D = tan⁻¹ (95/75)

D = 51.70983°

Rounding off the found angle to nearest 10th of a degree.

D = 51.7°

The graph of the function f(x) = (x − 3)(x + 1) is shown.
Travka [436]

Answer:

Real values of x where x < -1

Step-by-step explanation:

Above the x-axis, the function is positive.

The function is decreasing when the gradient is negative.

The function has a positive

{x}^{2}

coefficient, therefore the vertex is a local minimum;

This means the gradients are negative before the vertex and positive after it;

To meet the conditions therefore, the function must be before the vertex and above the x-axis;

This will be anywhere before the x-intercept at x = -1;

Hence it is when x < -1.
