Answer:
Step-by-step explanation:
Remember that
If angle t belong to the First Quadrant
then
The value of sin(t) and cos(t) are positive values
we know that
---> by trigonometric identity
we have
substitute
Answer:
The first part is B= -2t + 95.
Step-by-step explanation:
Every hour the battery drops by 2 so the equation is
current battery charge= (time)(-2)+(starting battery charge)
Answer:
50, 48, 14
Step-by-step explanation:
Go through them one by one. The side lengths of a triangle should all plug in to the formula a^2 + b^2 = c^2. The longest side is always c because it is the hypotenuse. The other two sides are interchangeable.
8^2+ 14^2 should equal 17^2.
That simplifies to
64+196=289
That can't be true because the units digits add to 10 instead of 9.
The same method applies to 3, 5, and 6 but from experience I know that this already isn't an option.
For 50, 48, and 14, you can divide everything by 2, resulting in 25, 24, and 7.
576+49 should equal 625.
That is true.
For 53, 48, and 24
576+2304 should equal 2809.
That isn't true, it equals 2880.
You need to make this in a mixed number form.
The answer is C, as it is rounded to 2 decimal places / 3 significant figures, which is more than the others.
