Answer:
dy/dx=sec^2^(x)-(-csc^2(x)
=sec^2(x)+ csc^2(x)
so solution is E
Answer:
AC = 10
Step-by-step explanation:
Do you really need the explanation it seems like you are taking a test. I answered one of your questions a few seconds ago.
a^2+b^2=c^2.
8^2 + 6^2 = c^2
64 + 36 = c^2.
100 = c^2.
Square root of it all equals to
c = 10.
Well for two positive numbers subtracted to equal a negative number, the first number must have a value that is less than the second number. (Ex. 3-4= -1) In this case, you can conclude that x is less than y! (x<y)
answer:
gradient is 4
Step-by-step explanation:
gradient is another way of saying slope
slope in the math is often used to show the speed of something
it's the m in y= mx+b
make the equation look like
y = mx + b
2y - 8x = -2
2y = 8x - 2
y= (8x-2)/2
y=4x-1
gradient is the number next to x
answer : gradient is 4
500 = 10x + 2 * 15 * 5 + 15x
500 = 25x + 150
500 - 150 = 25x
350 = 25x
x = 14
Triangular ends: 14 * 10 = 140
Base rectangle: 14 * 15 = 210
side rectangles: 5 * 15 * 2 = 150
140 + 210 + 150 =
