X^(3/5) = 1.84
x^(3/5) = (1.84)
Raise both sides of the equation to (5/3).
This is so that on the side with x, 3/5 * 5/3 = 1.
(x^3/5 )^5/3 = (1.84)^(5/3)
x^(3/5 * 5/3) = 1.84^(5/3)
x^1 = 1.84^(5/3)
x = 1.84^(5/3)
But remember we are solving for x^2.
x = 1.84^(5/3)
x^2 = (1.84^(5/3))^2
x^2 = 1.84^(5/3 *2 )
x^2 = 1.84^(10/3)
Use a calculator here.
x^2 = 1.84^(10/3) ≈ 7.63
Option A.
Cheers!
If sqrt x is around 3.4
x=(3.4)(3.4)=11.56
So x is in between 11 and 12 or
11
Hope this can help.
Answer:
- 1, 1, - 3
Step-by-step explanation:
To obtain the value of f(1), we require the corresponding value of y from the graph when x = 1
From the graph
when x = 1 the value of y on the graph is - 1 ⇒ f(1) = - 1
Similarly
f(3) means what is the value of y corresponding to x = 3
From the graph when x = 3 then y = 1 ⇒ f(3) = 1
and f(- 1) = - 3
Okay, so:
You would want to find what 1/10 of the laptop costs. That would be the 10% of money left in Kai's account.
So,
423*.1
(you have to turn the percentage into a decimal; 10%= .10
423*.1= 42.3
So, Kai has 42.3 dollars left to buy a scanner. He only has 10% of his bank account left to spend on the scanner.
I hope this helps!
