Assuming cos means cos(x);
Combine all like terms: cos(x)(√2 - 12)= -1
Isolate x: cos(x)= -1/(√2 - 12)
cos(x)=0.0944
x=cos⁻¹(0.0944)
x= 84.57 degrees or (360-x=275.42 degrees)

Answer:
24 and 15
Step-by-step explanation:
Answer:
2)8%
3)=
$
26.46
4)multiply $1.50 and 60%, which will give you 0.9. now multiply $1.50 and 0.9 and that'll give you$1.35. lastly, add $1.50 and $1.35 and that'll give you the answer which is $2.85.
5)15 % of $1580 is $237
6)25%

The geometric mean of two numbers x and y is √(xy).
So, if the geometric mean of 3 and a is 9 =>
9 = √(3a)
=> 9^2 = 3a
=> a = 9^2 / 3
a = 81 / 3
a = 27
Answer: the value of a is 27.
Answer:
B
Step-by-step explanation:
1. In order to determine the inequality, you must first solve the solution set to determine what x is less than.
So you would do this:
1 + 2x < 9 Subtract 1
2x < 8 Divide by 2
x < 4
2. Next, you need to understand the difference between an open circle and a closed circle shown on the solution sets.
An open circle is equal to the following inequalities:
<, >
A Closed circle represents inequalities in situations such as:
greater than or equal to, or less than or equal to
3. Because the inequality above represents only less than or greater than the inequality sets should have an open circle being used.
Since x is less than 4 it should be moving to the left of the line inequality set.
