Answer:
A
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° =
=
= 
Multiply both sides by 7, thus
AC = 7sin40° → A
The <em><u>correct answer</u></em> is:
A) as the x-values go to positive infinity, the functions values go to negative infinity.
Explanation:
We can see in the graph that the right hand portion continues downward to negative infinity. The right hand side of the graph is "as x approaches positive infinity," since x continues to grow larger and larger. This means as x approaches positive infinity, the value of the function approaches negative infinity.
X^2-22x-48=0
x^2-24x+2x-48=0
x(x-24)+2(x-24)
(x+2)(x-24)
Solve by grouping if you are able to find distinct factors that multiply to the last term and add to the middle term...this method is rather easy with easy to manage numbers. Complete the square if you cannot find distinct factors that multiply to the last term and add to the middle term. Completing the square helps when the equation is in the form of a parabola.
1. Change both numbers to common base.
2. Use quotient rule 
e)
You can write 9 as 3², then both numbers have the same base.
, where x is the exponent
I cannot really see the exponents because picture is bad quality.




You want to replace x and y with actual numbers, but as I said the picture is too bad.
f)
Convert to base 4, then quotient rule.
g)
Use the quotient rule, you already have same base.
h)
Convert to base
, then quotient rule.
