Answer:
a = 10 and b = 5
Step-by-step explanation:
We write out f(x)= ab^x for x = 0 and x = 3 to create two equations in a and b that must be solved simultaneously:
(0, 10): 10 = a*b^0
This tells us that 10 = a*1, or a = 10.
(3, 1250): 1250 = a*b^3 => 10*b^3, or
1250 = 10*b^3, or
125 = b^3. Taking the cube root of both sides, we obtain b = 5.
a = 10 and b = 5
Firstly, you've got to expand the brackets, this becomes;
8a-4= -10a+ 50
You've then got to eliminate the -10a and you do this by adding 10a to both sides,
This then becomes 18a-4=50
You've then got to add 4, to eliminate this, which then becomes 18a=54
You've then got to divide both sides by 18, and this becomes 3.
Therefor, a=3
Hope this helps :)
<span> x | f(x)
25 | 2
125 | 3
625 | 4
From my research, the above table belongs to the question. The values in x show increasing exponential values of 5, where:
5^2 = 25
5^3 = 125
5^4 = 625
As for the case of f(x), they are the values of the powers. So the logarithmic function that would explain the values of x and f(x) would be:
A base-5 function:

PEMDAS is important
Parentheses
Exponents
Multiplication
Division
Adding
Subtracting
There's no parentheses or exponents, so the first is multiplication. 9*3 is 27. Next is division, 6/2 is 3. Next is adding.
15+3+27=45
Answer:
false in all cases
Step-by-step explanation:
1) they are not supplementary ,cuz sum is not 180
2) false,cuz sum is not 90°
3) measure of AOB is not 60° and OC not bisecting them
4) measure of AOB is not 60° and OB not bisectijg AOC
