Answer:
6m
Step-by-step explanation:
You need to use trigonomtery: SOHCAHTOA
Since we are looking for the height, we should use the Sine rule:
Sine(37) = opposite/hypotenuse
We already have our hypotenuse which is 10
sine(37) = opposite/10m
Now we re-arrange to find the opposite(which is our height)
opposite = 10m x sine(37)
opposite = 6.018
Therefore height = 6 to the nearest metre
Hope this helps :)

Answer:
b) [tex]f^-1(x)[/tex]= ∛(4x-24)
c)2
Step-by-step explanation:
these ones are inverse functions
change the f(x) for y and make x the subject
y= x³/4 +6
(y-6)x 4 = x³
∛(4y-24)= x
then put x back were y is
[tex]f^-1(x)[/tex]= ∛(4x-24)
and to do c just put in 8 where x is
∛(4(8)-24)= 2

When n is positive, 1^n will always be 1
but........ (-1)^n will not always be -1
This is because there are parenthesis around -1
So n is even, then it will be 1 not -1
For example, n = 4
You will do -1 * -1 * -1 * -1 which is 1 not -1
but if n = 3
You will do -1 * -1 * -1 which is -1
Therefore, the second statement is incorrect resulting in Keiko being wrong

x^2-7x-34=10
Answers
Step-by-step explanation:
x2-7x-34-10=0
x2-7x-44=0
(x-11)(x+4)=0
x= 11 or x= -4
Answer:
x = 11 or x = -4
Step-by-step explanation:
x^2 - 7x - 44 = 0
-11 + 4 = -7, -11 × 4 = -44
(x -11)(x + 4) = 0 or (x + 4)(x - 11) = 0 Both are same way: O
x = 11 or x = -4 would be the answer : )

Without calculating, predict whether the area of the rectangle will be greater or less than 25 square meters if the length is 5.25 meters.
Answers
Answer:
depends on the other side, so... maybe
Step-by-step explanation:
If you have a rectangle and you know one side is 5.25, then if the perpendicular side looks about the same length or longer, then the area of the rectangle is at least 25.
Imagine you have a rectangle with a known base of 5.25, then if the rectangle is at least as tall as it is wide, then the area is over 25. If the rectangle is very close to a square then the area should be near 25, and if the rectangle is visually shorter than it is wide then the area is less than 25
