Answer:
Slope is 2.
Step-by-step explanation:
So to find slope, we need to take the change in the y value, and the change in the x value, and then divide them. This may be confusing, so here is just 3 formulas in 3 seperate steps that we use to find it:
Step 1 -
Step 2 -
Step 3 -
So lets start by doing step one.
All we need is to look for two x values. Lets use 5 and 6:
6-5=1
So 1 is our change of x. This is our 1st step.
Next we can use 2 y values, note that these should be the 2 y values that go wiht the x values above. So this means we have to use -3 and -1:
-1-(-3) = 2
So 2 is our change in y. This is our 2nd step.
Now lets plug this into:
:
So our slope is 2. Completing our 3rd and final step.
Hope this helps!
Answer:
tita = 0 , 180, 270, 360. ( tita = 0 ≤ x ≤ 360).
Step-by-step explanation:
sin tita + sin ^2 tita = 0
sin tita( sin tita + 1) = 0
sin tita = 0, - 1.
For angles between 0 and 360 inclusive sin = 0 gives 0, 180 and 360 degrees. The angle whose sine is -1 is 270 degrees.
tita = 0 , 180, 270, 360.
Answer:
1. The is between 3 and 4.
2. The is between 7 and 8.
3. The is between 4 and 5.
4. The is between 9 and 10.
5. The is between 6 and 7.
Step-by-step explanation:
1. : 10 is near the perfect squares 9 and 16, which would mean its answer is between their square roots which are 3 and 4.
2. : 10 is near the perfect squares 49 and 64, which would mean its answer is between their square roots which are 7 and 8.
3. : 10 is near the perfect squares 16 and 25, which would mean its answer is between their square roots which are 4 and 5.
4. : 10 is near the perfect squares 81 and 100, which would mean its answer is between their square roots which are 9 and 10.
5. : 10 is near the perfect squares 36 and 49, which would mean its answer is between their square roots which are 6 and 7.

Step-by-step explanation:
The circumference of a circle can be found using the following formula:
where d is the diameter. We are given the radius, so let's find the diameter.
The diameter is twice the radius.
The radius is 15 feet.
Multiply.
Now we know the diameter. Substitute 30 feet in for d.
We are using 3.14 for pi, so substitute it in.
Multiply.
The circumference of the circle is 94.2 feet.
