<h2><u>Direct answer</u> :</h2>
Width of the enlarged photograph = 14 cm
<h2><u>Steps to derive the correct answer</u> :</h2>
Length of a small photograph = 6 cm
Width of a small photograph = 4 cm
Length of the photograph when enlarged = 21 cm
Let the width of the photograph when enlarged be x.
Which means :






Thus, the value of x = 14
Therefore, the width of the enlarged photograph = <u>14 cm</u>
Answer:
One solution. (x,y) = (-5,25)
Step-by-step explanation:
y = -5x
x + y = 20
x + (-5x) = 20
-4x = 20
x = -5
y = -5 (-5)
y = 25
<span>Ans : Note that:
sin(x) = sum(n=0 to infinity) [(-1)^n * x^(2n + 1)]/(2n + 1)!.
Then, since the series is alternating, the error in the approximation found by taking the first n terms of the series is no bigger than the n+1'th term. In other words:
E ≤ a_n+1 = x^(2n + 3)/(2n + 3)!.
(Note that a_n does not include (-1)^n, the alternating part)
We need that 1/6 ≤ x^(2n + 3)/(2n + 3)!. Given |x| < 1, n = 2 will be the least integer solution. Thus, we need 2 + 1 = 3 terms.</span>
Answer: 10,500 hits
Step-by-step explanation:
I WANT BIG BRAIN! I WANT BIG BRAIN AHAHHHHHHH!!!!!!!
ok there are a number of ways to go about this
it is unclear whether or not the YT content creator will get one pound for 500 hits
i honestly dont know but i am going to assume it will
1000 times 20 (we are plugging in a test variable, 20, here)
so lets say we have 20,000 hits
lets divide that by 1000 and we get 20. 20 times 2 is 40 pounds so obviously thats too much
lets try 1000 times 10
so we have 10 times 2 and thats 20 pounds. we are closer
10,500 hits
(i put in 500 because half of 1000 is 500 and that will give you one pound instead of two)
Answer: x children and (481-x) adults.
1.25x +2.25(481-x) = 865.25
1.25x +1082.25 -2.25x =865.25
x= 217
so 217 children and 481-217 = 264 adults
hope this helped <333
