Answer:
Hi there!
Your answers are:
1) 38^10
2) 20^3
Step-by-step explanation:
1) Theres a property that goes like this:
(x^m)^n = x^mn
When you do a power of a power, you multiply them together!
2) There's a property that looks like this:
x^ m / x^n = x^ m-n
When dividing exponents, subtract!
Hope this helps!
F(x) = 4x - 9
let f(x) = y, this implies that x = f⁻¹(y)
y = 4x - 9 Let us solve for x.
4x - 9 = y
4x = y + 9
x = (y + 9)/4
Recall that x = f⁻¹(y),
x = (y + 9)/4
f⁻¹(y) = (y + 9)/4
That means that for f⁻¹(x)
f⁻¹(x) = (x + 9)/4
Hope this explains it.
Answer:
The domain is {x:x is a real number}
The range is {y:y is only 4}
Step-by-step explanation:
The domain of the function is the values of x
The range of the function is the values of y
f(x) = 4 is represented graphically by a horizontal line // to x-axis from y = 4
Every point on the this line has different values of x but same value of y
ex: (-1 , 4) , (5 , 4) , ( 0.1 , 4) , ................
So f(x) = 4 is called constant function
Answer:
22cm,24cm,24cm
Step-by-step explanation:
Let us call one of the other sides x
the shortest side = 2x-26
in an isosceles, 2 sides are equal (x in this case)
so we now have sides of x,x and 2x-26
form an eqution from this.
4x-26=70
4x=96
x=24
24 x 2 = 48 - 26 = 22
thus, the shortest side is 22cm and the other sides are both 24cm
