How to solve 4+|7-m|=5
notka56 [123]
When
|a|=b
assume
a=b and -a=b
so

4+|7-m|=5
minus 4 from both sides
|7-m|=1
assume
7-m=1 and
-(7-m)=1

7-m=1
minus 7 both sidees
-m=-6
times -1 both sides
m=6

-(7-m)=1
distribute
-7+m=1
add 7 to both sides
m=8

m=6 and 8

Use the unit circle to find cos Θ.
zalisa [80]

Answer:

\frac{\sqrt{2}}{2}

Step-by-step explanation:

Start by determining the simpler angle 2\pi-\theta (or, the complement of the highlighted angle in red on your image). The cosine of that angle is

\cos (2\pi-\theta) = \frac{x}{1}=\frac{\frac{\sqrt{2}}{2}}{1}=\frac{\sqrt{2}}{2}

Now, back to the actual red-circled angle. That one is going in the negative direction and ends up in the same position on the unit circle. Since cosine is an even function, its value is the same whether you evaluate at an angle theta, or its complement 2pi-theta. So, the final answer is: \frac{\sqrt{2}}{2}

Which expression do you solve first
hammer [34]

Answer:

The first thing you would solve is 10^2.

Step-by-step explanation:

This is because in the order of operations, parenthesis comes first - which you don't have any of - and then exponents come second.

The correct answer should be -2.

Because we're reducing - 1/3 by an additional 1 2/3, this makes it -2.
