<h3>
Answer: x = 65.4</h3>
==================================================
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(x) = 5/12
x = arccos(5/12)
x = 65.375681647836 which is approximate
x = 65.4 after rounding to one decimal place
Make sure your calculator is in degree mode. The arccosine function is the same as the inverse cosine function (shortened to 
).

the vertex is (h,k)
the constant, a, deterimines the size and direction
if a>0, then the parabola opens up and the vertex is the minimum
if a<0 then the parabola opens down and the vertex is the maximum
so we are given
1>0 so it opens up
vertex is (-2,4)
the vertex is a minimum
the vertex is (-2,4) and the graph has a minimum
Answer:
0.85
Step-by-step explanation:
6.80 divied by 8
Philip is 5 years old and Jon is 19 years old now.
Step-by-step explanation:
Step 1 :
Let x be the age of Philip Now
Since Jon is 14 years older than Philip,
Age of Jon = 14 + x
Step 2 :
After 2 years,
Age of Philip = x+ 2
Age of Jon = 14+x+2 = 16+x
Step 3 :
Given that in 2 years, Jon will be 3 times as old as Philip.
So we have 16 + x =3(x+2)
=> 16 + x = 3x +6
=> 2x = 10 = x = 5
Hence age of Philip is 5 years
Age of jon = x + 14 = 5+ 14 =19 years
650,000 is the awnser because when you round if it's 5 or higher you add 1 is its less than 5 you leave it
