Answer:
David got it correctly
Step-by-step explanation:
5.6 x 10=56 not 0.56
7.21 X 100= 721 not 0.721
There are no choices so I’m going to assume this is simplification.
Answer:
3/4 —> this is the most simplified version of that fraction.
Explanation:
48/64 can be divided by multiple things to gain fractions. You could divide it by 2 repeatedly until arriving to a fraction wherein you couldn’t split anymore.
Ex.) 48/64 = 24/32 = 12/16 = 6/8 = 3/4
All of the above answers are equivalent to 48/64.
An easier way to reach the final answer of 3/4 would be to find the greatest common factor of 48/64. You can divide both by 16 and then get to 3/4.
Hope this helps!
Answer:
There is an 144 degree difference.
Step-by-step explanation:
112=(-32)+x
solve like a regular equation which will give you 144
(add 32 to 112)
Answer:
x ≈ 1.9087
Step-by-step explanation:
We don't know what methods you learned in class, but here's one way to solve the equation.
Make x the exponent of a constant:
5^(x+2) = 3^(3x)
(5^x)(5^2) = (3^3)^x
25(5^x) = 27^x
Put the powers all on one side of the equation and everything else on the other side.
25 = (27^x)/(5^x) = (27/5)^x = 5.4^x
Take logarithms.
log(25) = x·log(5.4)
x = log(25)/log(5.4)
x ≈ 1.9087
Let's plug in x = 2.
f(x) = x^2
f(2) = 2^2 ... replace every x with 2
f(2) = 4
----------
Now plug in x = 3.
f(x) = x^2
f(3) = 3^2 ... replace every x with 3
f(3) = 9
-----------
And x = 5 as well.
f(x) = x^2
f(5) = 5^2 .... replace every x with 5
f(5) = 25
-----------
We see that
f(2)+f(3) = 4+9 = 13
which is not equal to f(5) = 25.
So f(2)+f(3) = f(5) is false.
------------
Another way to phrase why it doesn't work is because (2,3,5) isn't a pythagorean triple. The equation 2^2+3^2 = 5^2 is false.
If it said f(3)+f(4) = f(5), then it would be correct because 3^2+4^2 = 5^2 is a true equation.
