\bf sin^2(\theta)+cos^2(\theta)=1\implies sin^2(\theta)=1-cos^2(\theta)\\\\
sec(\theta)=\cfrac{1}{cos(\theta)}
\\\\
-----------------------------\\\\
cos(t)[sec(t)-cos(t)]\implies cos(t)sec(t)-cos(t)cos(t)
\\\\\\
cos(t)\cdot \cfrac{1}{cos(t)}-cos^2(t)\implies 1-cos^2(t)\implies \boxed{sin^2(t)}

Jake rolls two standard number cubes. Find the probability that the sum of the roll is 5, given that one cube came up even and t
Ira Lisetskai [31]
A sum of 5 from two cubes is ALWAYS one odd and one even, so the condition does not change anything whatsoever.
To roll a 5, we can have (1,4),(2,3),(3,2),(4,1) out of a sample space of 36 outcomes.  So the probability is 4/36, or 1/9.

How to solve<br> (x+2) (x-3) = 0
suter [353]
Using the FOIL (First, Outside, Inner, Last) method, you multiply the two parenthesis together. First, you multiply x • x which = x^2, then outside, x • -3 = -3x. Next you multiply the inner number and variable, 2 • x = 2x, and finally the last values, 2 • -3 = -6. Then add all the values together (x^2 - 3x + 2x - 6) which equals the final answer x^2 - x - 6 :) Im not great at explaining but I hope this helps

Answer:

h = -6

Step-by-step explanation:

Use the quadratic formula

ℎ

√

2

h=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}

h=2a−b±b2−4ac​​

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

ℎ

h^{2}-36=0

h2−36=0

a={\color{#c92786}{1}}

a=1

b={\color{#e8710a}{0}}

b=0
