Answer:
40 years
Step-by-step explanation:
Hulian and Thomas together is 65 years
let us suppose hulian is X
now, so Thomas is x+15
so x+x+15=65
so 2x = 65-15
2x=50
x=25
Hulian is 25
and Thomas is 25+15=40
<span>first, we are going to define variables as the following:
a = 0
a = π/2
n = 4 rectangles
Δx = [ b - a ] / n ------>Δx = [ π/2 - 0 ] / 4 = π/8
right endpoints :
sum( seq( 4 cos(x) * π/8 , x , 0+π/8 , π/2 , π/8 ) ) = 3.163065 underestimate
left endpoints:
sum( seq( 4 cos(x) * π/8 , x , 0 , π/2-(π/8) , π/8 ) ) = 4.733861 overestimate
the reason because the actual estimate by integral as the following:
π/2
∫ 4cos(x) dx = 4

Answer:
Vertically opposite angles are equal.
Therefore,
<h3><u>x=27</u> is the right answer.</h3>
The side opposite and the hypotenuse are used so you would use sin(29)=14.2/y
Which becomes y=14.2/sin(29) hence =29.28984782 cm. round it as per necessary
Answer:
3.33times 10^7 because when it is possible to substract 2.24times10^5 from it
