Answer:
First notice that θ is in quadrant I, where the sine and tangent will also be positive.
Then draw the angle in quadrant I. Drop a perpendicular to the x axis.
Since cosθ= 7/25, label the horizontal leg 7, and the hypotenuse 25; the vertical leg will be 24 by Pythagorean theorem.
Then sinθ=vertical/hypotenuse= 24/25 and tanθ= vertical/horizontal= 24/7
Step-by-step explanation:
Answer:
They Would be if they Have a pattern from left to right such as +2 or -5.
Step-by-step explanation:
If an example is counting up from 15 to 31 and 0 to 8 the pattern is Adding Two. So if the numbers decrease or increase in a certain way, then you can find out what it is and thn bam, your answer to the question.
Answer:
22.38 g of silicone-32 will be present in 300 years.
Step-by-step explanation:
A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay and its given by
where,
= quantity of the substance remaining
= initial quantity of the substance
= time elapsed
= half life of the substance
From the information given we know:
- The initial quantity of silicone-32 is 30 g.
- The time elapsed is 300 years.
- The half life of silicone-32 is 710 years.
So, to find the quantity of silicone-32 remaining we apply the above equation
22.38 g of silicone-32 will be present in 300 years.
1 and 1/4 cup of raisins and 2 and 1/2 cups of nuts for a total of 3 and 3/4 cups.

<span>Round 287.9412 to the nearest tenth.
Lets solve this!
To round to the nearest tenth, you need to know the tenth place--------
In the number, 287.9412, nine is in the tenth place. You need also make sure whether the number next to 9 is greater than 5 or not.
</span><span>287.9412 =287.941=287.94=287.9=288=290
Thus, your answer is 290.
Hope I helped.
