Secx = 1/cosx
cot x = 1/tanx
1 + tan^2(x) = sec^2(x)
minus tan^2(x) on both sides,
1 = sec^2(x) - tan^2(x)
sec(x)/cos(x) - tan(x)/cot(x)
=1/cos^2(x) - tan^2(x)
= sec^2(x) - tan^2(x)
= 1
<u>Fraction</u> . . . 68/100
<u>Fraction in simplest form</u> . . . 17/25
<u>Mixed number .</u> . .
A mixed number is a whole number plus a fraction. Since part of it is a whole
number, a mixed number is always more than ' 1 '. But .68 is less than ' 1 ',
so there's nothing you can do to it to make it a mixed number. It doesn't have
what it takes.
Answer:
The Second choice y+5=-3/4(x-2
Step-by-step explanation:
4y=3x+8 solve for y so it's y=-3/4x+2
and use the slope which is -3/4
2 = x then 5 = y
you used to pass through formula and plug it in soooo it's
y+5=-3/4(x-2)
sorry if this doesn't make any sense, I'm terrible at explaining
Answer:
3(a + 5b + 7c) and 2x(2 + 5y + 11z)
Step-by-step explanation:
3a + 15b + 21c
3(a + 5b + 7c)
4x + 10xy + 22xz
2x(2 + 5y + 11z)
To find coterminal angles you add or subtract multiples of 360 (since this is a full revolution of a circle).
72 + 360 = 432 + 360 = 792
72-360 = -288
Letter C is NOT coterminal
