Answer:
Step-by-step explanation:
hello :
(x-4)²(x+3)² = -1
means : ((x-4)(x+3))² = - 1 this equation has no solutions in R
because for all x in R : ((x-4)(x+3))² ≥ 0
Answer:
Area, A = 63.6 square yards
Step-by-step explanation:
A trapezoid refers to a quadrilateral that is convex in shape; as such it has no equal sides and no parallel sides.
Let the height of a trapezoid be h.
Let the top base of a trapezoid be b1.
Let the bottom base of a trapezoid be b2.
Therefore,
Given the following data;
Length, b1 = 5 yards
Width, b2 = 5.6 yards
Height, h = 12 yard
To find the area of geometrical shape (trapezoid), we would use the above formula;
A = 1/2 (b1 + b2) * h
Substituting into the formula, we have;
A = ½ * (5 + 5.6) * 12
A = ½ * (10.6)*12
A = 5.3 * 12
Area, A = 63.6 square yards

Step-by-step explanation:
Explanation:
the initial statement is
y
∝
x
to convert to an equation multiply by k the constant
of variation
⇒
y
=
k
x
to find k, use the given condition for x and y
y
=
10
when
x
=
5
y
=
k
x
⇒
k
=
