Answer:
x + x = 10
x - x = 5
2x = 10
x = 10/2
x = 5
Step-by-step explanation:
Answer:
For 4 seconds the projectile will be in the air.
Step-by-step explanation:
The function f(x) = –10(x)(x – 4) represents the approximate height of a projectile launched from the ground into the air as a function of time in seconds, x.
Now, if the projectile stays for x seconds in the air then after x seconds its height will be zero.
Hence, 0 = - 10x(x - 4)
⇒ x = 0 or x = 4
Now, x cannot be 0 as at time = 0 the projectile starts its motion.
So, for 4 seconds the projectile will be in the air. (Answer)
On that specific day, the US dollar was worth more than the Canadian dollar and less than the Australian dollar.
<h3>Define the term comparison of numbers?</h3>
- In arithmetic, comparing numbers is described as the process or method of determining whether one number is smaller, bigger, or equal to some other number based on their values.
The equation u = 0. 99c depicts the value of the US dollar in relation to the Canadian dollar on a specific day.
- c = the Canadian dollar's value
- u denotes the value of the US dollar.
From the equation,
For Australian dollar; (from table)
u = 0.95 c -->
a = 1/0.95 u
a = 20/19 u
(20/19u - u)/ u = 1/19 ....1
For Canadian dollar:
u = 0. 99c
c = 1/0.99 u --> c = 100/99 u
Thus,
(100 u / 99 - u)/ u = 1/99 .....2
From 1 and 2]
1/19 > 1/99
Thus, on that specific day, the US dollar was worth more than the Canadian dollar and less than the Australian dollar.
