A) 6 X 100 000 000
A= 600 000 000
B) 3 X 1 000 000 000
B=3 000 000 000
C)9 X 100 000
C=900 000
D)2 X 10 000 000 000
D= 20 000 000 000
Answer:
let x and y be the two number then according to question ,
xy=4 2/9
or, xy= 38/9
if one of the number is 38 then,
38x=38/9
or, x= 1/9 is the correct ans.
Answer:
im so sorry bro
Step-by-step explanation:
For this problem, I think there is no need for the details of 12 inches width and 4 inches length. This is because an equation is already given. It was clearly specified that A as a function of θ represents the area of the opening. Then, we are asked to find exactly that: the area of opening. Moreover, the value of θ was also given. Therefore, I am quite sure that the initial details given are for the purpose of red herring only.
So, all we have to do is substitute θ=45° to the function given.
A = 16 sin 45° ⋅ (cos 45° + 1)
The angle 45° is a special angle in trigonometry. So, it would be easy to remember trigonometric functions of this angle. Sine of 45° is equal to √2/2 while cosine of 45° is also √2/2.
A = 16(√2/2) ⋅ (√2/2 + 1)
A = 8+8√2
A = 19.31 square inches
hello!
so the difference is 101 and here is why!
you want to minus -1 from 100
100 - (-1)
but because it is a double negative it will become addition
100 + 1
so the difference is 101 feet
i hope this helped :)
