Standard form of 7.09×10^4 is 70,900. Move the decimal place four places to the right.
The distance between you and your friend rounded to the nearest tenth is 10.7 feet.
<h3>How to find the length of a triangle using cosine rule?</h3>
The distance between you and your friend can be found using cosine rule.
Therefore,
c² =a² + b² - 2ab cos C
Therefore,
let
x = distance between him and his friend
x² = 7² + 6² - 2 × 7 × 6 cos 110°
x² = 49 + 36 - 84 × -0.34202014332
x² = 49 + 36 + 28.7296920394
x² = 113.729692039
x = √113.729692039
x = 10.6644124076
x = 10.7 ft

yo sup??
as mentioned earlier XUY is simply the summation of all the unique elements of X and Y
S=XUY
={-1,0,1,2,5}
Therefore your answer is option 1 ie
1.{-1,0,1,2,5}
Hope this helps.
Answer:
<h2> $1008</h2>
Step-by-step explanation:
We begin by calculating the amount after the 25% discount
= regular price*0.75
=£160*0.75
=$120
We then continue by calculating the the amount that must be paid when 20% VAT is added
= 120*1.20
= $144
Now Tara is going to spend 7 nights
Hence she will have to pay
144*7= $1008
Answer:
C
Step-by-step explanation:
We have the equation:
Add 10 to both sides to isolate the equation.
This is not factorable*, so we can use the quadratic formula:
In this case, <em>a</em> = 4, <em>b</em> = 5, and <em>c</em> = 10.
Substitute:
Simplify:
Since we cannot take the root of a negative, we have no real solutions.
Our answer is C.
*To factor something in the form of:
We want two numbers <em>p</em> and <em>q</em> such that <em>pq</em> = <em>ac</em> and <em>p</em> + <em>q</em> = <em>b</em>.
Since <em>ac</em> = 4(10) = 40. We need to find two whole numbers that multiply to 40 and add to 5.
No such numbers exist, so the equation is not factorable.
