Step-by-step explanation:
x approches negative infinity
so : |x|= -x
replace it in the expression
so :
= limx⇒-∞( -x/x) you take the terms with the highest degree
so limx⇒-∞ (-x/x) = -1
Answer:
Solution
Step-by-step explanation:
Rewrite logx729= 3 is an exponential form using the definition of a logarithm. If x and b are positive real numbers and b≠1, then logb(x)= y is equivalent to b^y = x.
X^3 = 729
Take cube root on both side and we get
x= 3√729
now we firstly simplify the 3√729
Rewrite 729 as 9^3
x = 3√9^3
pull terms out from under the redical, assuming positive real numbers
x=9
verify each of the solution by substituting them into logx729=3 and solving.
x= 9
Answer:
D
Step-by-step explanation:
If you multiply 3 and 7 you are saying she worked 21 hours when she only worked a total of 10 hours.
Answer:
truuuuue is theeee answer
Step-by-step explanation:
Answer for the first one - it's complicated, but that maths is correct
I kind of cheated and did it a different way than they'd expect. By doing 24 squared, that gives you 576.
since both angles are 45 degrees, then the sides are equal lengths. Therefore x squared times 2 = 576.
Because of this, x squared = 576 divided by 2, which equals 288.
Therefore the square root of 288 = 12 square root 2
