Answer:
-8
Step-by-step explanation
2 to the power of -1 = 0.5
5 to the power of -1 = 0.2
0.5/0.2 = 2.5
So,
(2.5)2 x -5/8 to the power of -1
-5/8 = -0.625
-0.625 to the power of -1 = -1.6
So,
(2.5)2 x -0.625
5 x -0.625
= -8
Step-by-step explanation:
The value of x is
x = 118° < being corresponding angles>
Hope it will help :)❤
ANSWER
EXPLANATION
The basic sine function is
The transformed sine function has equation
where a=1 is the amplitude
2π/b=2π is the period
c/b= 4 is the horizontal shift 4 units left.
d=-4 is a downward vertical shift of 4 units.
The required sine function is:
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.
Hello!
That problem looks pretty messy... let's clean it up! :D
so we have this -----> -0.3(0.7x - 0.9) = -1.83 let's get simplifying
-0.21x + 0.27 = -1.83 -----> I distributed the -0.3 among 0.7x and -0.9
-0.21x = -2.1 -----> I subtracted 0.27 on both sides of the equation
<u>x = 10</u><u /> -----> I divided -0.21 on both sides of the equation
The answer you're looking for is D!
I hope this helps! :D
