Answer:
4, 12, 16 (respectively)
Step-by-step explanation:
if you need one just comment and ill add one
Sure. So the hundreds digit is after the tens digit which is 3, so therefore it's 4. The millions digit is 7 places to the left, so it's 7. Ten thousands digits are 5 places to the left, so it's 9. The hundred thousands is 6 to the left, therefore 8. Finally, the thousands is 4 places to the left, so it's 0. Hope this helped!
Answer:
10(3)^x
Step-by-step explanation:
The function contains the points (2,90) and (4,810). Use the general form y=abx to write two equations:
90=ab^2 and 810=ab^4
Solve each equation for a:
a=90/b^2 and a=810/b^4
Since a=a, set the other sides of the equations equal and solve for b.
90/b2=810/b4
Cross multiply, then divide and simplify as follows:
90b^4=810b^2
b^4/b^2=810/90
b^2=90
b^3
Now, use the value of b and the point (2,90) to find the value of a.
90=a(3^2)
a=10
So, substitute answers in original equation for a final answer of f(x)=10(3)^x.
Answer:
20
Step-by-step explanation:
y=kx
X=2 & y= 10
10=2k
k=5
when y=100
100=5x
X=20
