Answer:
Step-by-step explanation:
f(x)= 12x2+5 should be written as f(x) = 12x^2 + 5; the " ^ " symbol signifies exponentiation and is mandatory.
Here's how we find the inverse function.
1. Apply the horizontal line test. if a horizontal line intersects the graph in more than one place, the function is not one-to-one and does not have an inverse for all x. However, if we focus on only [0, infinity), this part of the graph does have an inverse, which we can find as follows:
2. Replace 'f(x)' with 'y: y = 12x^2 + 5
3. Interchange x and y: x = 12y^2 + 5
x - 5
4. Solve for y: 12y^2 = x - 5; y^2 = ------------
12
x - 5
y = √(----------)
12
D, let me know if you need explanationn <33333
12 = 2^2 * 3
28 = 2^2 * 7
Here only 2 is common
So gcf of 12 and 28 = 2^2 = 4
Hope it helps !!
For example: 3-4d=13.
add 3 to both sides.
now you should have 4d=16
divide by 4 on both sides
your answer would be d=4
Answer:
She will cycle 85.169 miles in the third week.
(round if needed)
Step-by-step explanation:
56÷100=0.56 (this is 1%)
0.56 x 15 + 56 = 64.4 (you find 15% then add 56 (the original amount) because it's an increase of 15%)
repeat for the other 3 weeks
64.4÷100=0.644
0.644 x 15 + 64.4 = 74.06
74.06÷100=0.7406
0.7406 x 15 + 74.06 = 85.169
