Radius = half of diameter
radius = 4m
circumference of a circle = 2πr
circumference = 2(3.14)(4)
circumference = 25.12
The value of the expression sec (-π) is equal to -1 if the given expression is undefined.
As given in the question,
Given expression: sec (-π)
Standard position of unit circle: -π is representing semicircle with terminal point on negative x-axis with coordinates (-1, 0)
Hypotenuse = √ (-1)² + 0²
= 1
Value of the expression is given by
sec α = Hypotenuse / Base (x-coordinate)
⇒sec(-π) = 1 / -1
⇒sec(-π) = -1
Therefore, the value of the expression sec (-π) is equal to -1.

The formula for simple interest is: Total amount = Principal ( loan amount) x (1 + interest rate x time (years).
Using the given information you have:
Total = 7540 x (1 + 0.065 x 2.5)
Total = 7540 x (1 + 0.1625)
Total = 7540 x 1.1625
Total = $8,765.25
Answer:
y= -2x + 11
Step-by-step explanation:
standard form for lines is y=mx+b
m is the slope and b is the y intercept
we already know that m is -2, so we just need to figure out the intercept.
the point given is (7,-3)
points are written as (x,y) so we can plug it into the equation with 7 for the x and -3 for y
-3 = -2 (7) + b
-3 = -14 + b
11 = b
so the equation is y=-2x+11
Answer:
90 x 7= 630 minutes
