1. f(-6)=12
2. k(-4)=-68
Further explanation:
We have two functions whose values we have to find on certain points.
In order to find the values of function, the value is put in place of variable in the function.
So,
<u>1. f(a) = -2a</u>
We have to find, f(-6)
So putting -6 in function
<u>2. k(x) = -3x^2+5x</u>
We have to find, k(-4)
So putting -4 in function

Using a Laplace expansion along the first column, we have
The determinant of a 2x2 matrix is trivial,
So we have
The answer is 193.49 when it is rounded to the nearest hundredth(1/100 or 0.01)
Answer:
TWO PARALLEL LINES AND LINES WITH EQUAL LENGTHS
Step-by-step explanation:
As we all know a quadrilateral is a polygon with four sides(edges and corners). Trapezoid is a four-sided shape with opposite sides parallel while parallelogram is also a for sided shape that has its opposite sides paralleled.
NOW, a quadrilateral is said to be both a trapezoid and a parallelogram when there are two opposite parallel lines, which are lines with equal lengths.
