Answer:
58
Step-by-step explanation:
(2)(4) + (2)(-√-100) + (√-25)(4) + (√-25)(-√-100)
= 8 - 20i + 20i + 50 = 58
Answer:
Step-by-step explanation:
If the function f(x) has x-intercepts of -3 and -5 then the roots are and .
The factors of this function are and .
We can write the function in factored form as:
We expand using the distributive property to get:
Answer:
Option (3)
Step-by-step explanation:
Track is shaped as a rectangle with a semicircle on either side.
Therefore, length of the track = 2(Length of rectangle) + perimeter of a complete circle formed by joining the semicircles on each side.
= 2(96) + 2πr
=
= 192 + 35π
= 192 + 109.9
= 301.9 m
Since, Jake plans to run four laps.
Therefore, distance covered by Jake = 4 × 301.9
= 1207.6 m
