Answer:
43
Step-by-step explanation:
I would see a pattern like this
1 4 6 2 5 7 8 9 7 15 41 ?
------------------- ---------
start pattern key
then
15 = 8 × 2 - 1
a10 = a7 × a4 - a1
41 = 9 × 5 - 4
a11 = a8 × a5 - a2
? = 7 × 7 - 6 = 43
a12 = a9 × a6 - a3
You can try using PhotoMath bro, it solves a lot of math problems. By the way, I’m just letting you know. It’s an app you can download
75/25 = x/100
x = 300
ANSWER: 300
CHECK ANSWER: 300 x .25 = 75
Replace f(x) with y:
y = x^2 -1
swap the variables:
x = y^2 -1
Solve for y:
Add 1 to each side:
y^2 = x+1
Take the square root of both sides:
y = √(x+1)
To complete the solution use both the positive and negative values.
f^-1(x) = +/+√(x+1)
The last answer is the right one.
Answer:
the first one a²+b²=c²
14²+10²=c²
196+100=c²
296=c²
c=√296=17.20
and the last one=a²+b²=c²
x²+24²=25²
x²+576=625
x²=625-576=49 so x=√49=7
x²=49 and x=7
