Answer:
319 in²
Step-by-step explanation:
The applicable area formula is ...
A = 1/2(g)(e)·sin(F)
A = 1/2·(12 in)(55 in)sin(75°) ≈ 319 in²
The area of the triangle is about 319 square inches.
A vertical line is perpendicular to the x-axis because they would intersect to form a 90 degree angle.
Answer:
x = - 2 or x = 4
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 2 = 0 ⇒ x = - 2
The x- intercepts are at x = - 2, x = 4
Step-by-step explanation:
89 multiplied by negative 34 gives a negative answer, since positive multiplied by negative is negative hence,
(89) × (-34) = -3026
