Youre given the adjacent and hypotenuse, so you can use cosine. SOHCAHTOA
cos(37) = 48/x
x = 60.1
f(-4); f(x) = x2 + x - 4
Answer: 8
Step-by-step explanation: In this problem,
we're asked to find f(-4) or the value of the function when x = -4.
To find the value of the function when x = -4,we simply plug in a -4 for
the x in our function and we have (-4)² + (-4) - 4 or 16 + -4 - 4 which is 8.
So f(-4) = 8.

solve: |2x-1| ≥ 4x+3
Step-by-step explanation:
consider the sign as equals then
move 2x right side 3 on left
solve it
answer is 2
Question is: 2x - 1 >= 4x + 3
First, join the like terms together.
-> So 2x moves into 4x, meaning it becomes negative -2x on the other side.
-> The number 3 moves into the other side which also becomes negative.
Now the equation will look like this:
- 3 - 1 >= 4x - 2x
- 4 >= 2x
Put 2 on the other side with - 4, and it will divide (not plus or minus as 2 was combined with an unlike term).
It looks like this now:
- 4/2 >= x
- 2 >= x
This is the answer.

The length of the diagonal of a square is 30square root 2 find the perimeter of the square
Answer:
120.
Step-by-step explanation:
Using the Pythagoras theorem:
(30√2)^2 = x^2 + x^2 where x =length of each side of the square
1800 = 2x^2
x^2 = 900
x = 30.
So the perimeter = 4*30 = 120.

Apply the coupon to the loaf of bread first. $1.55 off a loaf of bread means subtracting this amount from the original price of bread.
$4.63 - $1.55 = $3.08If the loaf is cut into 14 slices, we should divide the loaf of bread's new price by 14.
$3.08 / 14 = $0.22The price per slice if Ellen uses her coupon is $0.22 per slice.

a teacher wishes to keep the students books in the cardboard which is 69.9cm long,24cm wide and 36.01cm high estimate how many exercise books he can put if each exercise book is 22cm long 19.5cm wide and 0.9cm thick
Answer:
156
Step-by-step explanation:
We are given that
Length of cardboard, l=69.9 cm
Width of cardboard, b=24 cm
Height of cardboard, h=36.01 cm
Length of book, l=22 cm
Width of book, b=19.5 cm
Thickness of book, h=0.9 cm
Volume of cuboid=lbh
Using the formula
Volume of cardboard=[tex]69.9\times 24\times 36.01 cm^3[/tex]
Volume of one book=[tex]22\times 19.5\times 0.9 cm^3[/tex]
Number pf exercise book=[tex]\frac{volume\;of\;cardboard}{volume\;of;one\;book}[/tex]
Number of exercise book=[tex]\frac{69.9\times 24\times 36.01}{22\times 19.5\times 0.9}[/tex]
Number of exercise book=156
