C, there are 3 options the first time, and after that, there are 3 options for each of those. So it would be C.
The answer is C because y=-3/4 which is a negative.
jonas wants to mail a package that weighs 4.2 kilogram. how much dose the package weigh in pounds?
we know that
1 kg = 2.20462262185 lb
1 kg=2.2 lb
we have
4.2 kg
Convert to pounds
so
4.2 kg=4.2*(2.2)=9.24 pounds
therefore
the answer is 9.24 pounds
He still has 75% of his income left because 1500/375=4 so he spent 1/4 of his check and has 3/4 left.
Answer:
option b)
tan²θ + 1 = sec²θ
Step-by-step explanation:
The Pythagorean trigonometric identity is a trigonometric identity expressing the Pythagorean theorem in terms of trigonometric functions.
hypotenuse² = height² + base²
Given in the questions are some pythagorus identities which except of b) are all incorrect as explained below.
<h3>1)</h3>
sin²θ + 1 = cos²θ incorrect
<h3>sin²θ + cos²θ = 1 correct</h3><h3 /><h3>2)</h3>
by dividing first identity by cos²θ
sin²θ/cos²θ + cos²θ/cos²θ = 1/cos²θ
<h3>tan²θ + 1 = sec²θ correct</h3><h3 /><h3>3)</h3>
1 - cot²θ = cosec²θ incorrect
by dividing first identity by sin²θ
sin²θ/sin²θ + cos²θ/sin²θ = 1/sin²θ
<h3>1 + cot²θ = cosec²θ correct</h3><h3 /><h3>4)</h3>
1 - cos²θ = tan²θ
not such pythagorus identity exists
