Answer:
0 +256i
Step-by-step explanation:
According to Euler's formula, ...
(4 cis π/8)^4 = (4^4) cis (4×π/8) = 256 cis π/2 = 0 +256i
_____
"cis" is an abbreviation sometimes used for "cosine + i×sine". It simplifies writing the expression. Engineers sometimes simplify it further, writing 4∠(π/8) for the expression in this problem statement.
Multiply the amount of inches it is by 30 and you will know what the size is in feet.
A circle exists as a curve sketched out by a point moving in a plane. The circle's perimeter exists the length of the line of the circle that creates the circle. It exists generally named the circumference of the circle.
<h3>What is a circle?</h3>
A circle exists as a curve sketched out by a point moving in a plane so that its distance from a given point exists constant; alternatively, it exists as the shape created by all points in a plane that exists at a set distance from a provided point, the center.
A.) The statement that rejects this characterization of the circle exists that the given point should be at the circle's center.
B.) An illustration of an indefinite term exists in the perimeter of the circle, The circle's perimeter exists the length of the line of the circle that makes the circle. It exists generally named the circumference of the circle.

Answer:
Step-by-step explanation:
y= -5x/2+1

Actually Welcome to the Concept of the Similarities.
Since here, first figure is a Triangle, hence similarity of a triangle is given by ratio of it sides and make them equate,
hence for,
1.) 16/12 = x/9 ===> 4/3 = x/9 ===> x = 9*4/3 ==> x = 36/3
hence the value of x is 12 , ===> x = 12 .
2.) here,in the case of a Reactangle the relation is such that, length = 2* breadth,
hence we apply the relation,
x = 2*4.5 ===> x = 9 units.
