Answer and Explanation:
Given the function:
ℎ(t)= −16t+5t+250
Where the variable t is measured in seconds. We can plug in t=20 seconds in the function to measure the height in feet of the bungee jumper after 20 seconds.
h(t)= -16×20+5×20+250
h(t)= -320+100+250
h(t)=350-320
h(t)= 30feet
height in feet of the bungee jumper after 20 seconds = 30 feet
There are officially two people aboard the space station
Answer: 2
Answer:
(-6, 0).
Step-by-step explanation:
x^2 + 36y^2 + 12x = 0
Convert to standard form:
(x + 6)^2 - 36 +36y^2 = 0
(x + 6)^2 + 36y^2 = 36
Divide through by 36:
(x + 6)^2 / 36 + (y - 0)^2/ 36 = 1
Now compare this with the general form:
(x - h)^2/a^2 + (y - k)^2/ b^2 = 1
We see that the center (h, k) = (-6, 0).
Answer:
The left side of the equation is ignored
i is treated as -1, which it is not, it is instead the square root of negative 1.
To solve it properly we get:
(2 - 5i)(5 + 2i)
= 10 + 4i - 25i - 10i²
= 10 + 21i + 10
= 20 - 21i
Alright, so we do 100*(0.9)^5 due to that you do 0.9 5 times. This equals to approximately 59
