It should be 2x-156 if that’s not it then i have no clue
Mhm, absolutely. Notice that we do not have a common unit circle value for any division of 8. But we do have a value for is 7pi/4. Now in order to actually get the value of 7pi/8, we use a half angle formula. So what we do is we will write out the formula and plug 7pi/4 into that formula, this will give us the value of 7pi/8. So the formula we need to plug 7pi/4 into is this:
<span>±<span><span><span>1+cos2θ</span>2</span><span>−−−−−−−−−</span>√</span></span><span>SO if you plug in 7pi/4 for theta in that formula, you think you could simplify it to find 7pi/8?</span>
Answer:
C and E for sure
Step-by-step explanation:
Answer:
Width is 2 and Length is 6
Step-by-step explanation:
- As the data is given, the area of a playground is 12 square yards.
- The length of the playground is 3 times longer than its width.
- Let width is x, length is 3 times therefore, length = 3x
As we know the formula for area,
So by putting values in this formula,
=> 3x2 = 12
=> x2 = 12/3,
=> x2 = 4 ,
by taking square root we get x= 2,
- the width is 2 and length is 3 times hence, length is 3(2) = 6.
A total of 1,716 selections of the 7 flowers are possible.
Step-by-step explanation:
Step 1:
There are 13 flowers from which Jeanine Baker plans to use 7 of them.
To determine the number of selections that are possible we use combinations.
The formula for combinations is;
.
Step 2:
In the given formula, n is the total number of options and r is the number of options to be selected.
For this question,
and
.
So 
So a total of 1,716 selections are possible.
