I=prt. I=375x .035x 4. I= 8.85x4. I=35.42
So first you subtract 2001-1682=319.
There is just 1 step, and it is hard to show work here.
Hope this helped! :)
Answer:
D
Step-by-step explanation:
Assuming that the expression is referring to sin²(2πft) and not sin²(2)πft, we can solve as follows:
One trigonometric identity states that sin²x+cos²x = 1. We want to express this in terms of cos²x, so we need to solve for sin²x. Subtracting cos²x from both sides, we get 1-cos²x = sin²x. Plugging (2πft) for x, we get
1-cos²(2πft) = sin²(2πft)
We can plug that into our equation to get
P = I₀²R(1-cos²(2πft)), or D
Your answer is 1/12

Explanation:
The given passage talks about the impact of chemicals on the ecosystem. The speaker narrates how the ecology belongs to plants, animals, and humans, though man seemed intent to destroy it for himself.
The blanks in the given passage are filled with the appropriate words as follows-
Ecology is the study of how <em><u>(1) plants</u></em>, animals, and people live <u><em>(2) together</em></u> and help each other. But man sometimes forgets he <em><u>(3) is</u></em> a part of the <u><em>(4) family</em></u> of all living things. Here is an example. A planter is <u><em>(5) talking</em></u> about killing <u><em>(6) weeds</em></u> on his land. He remembers his first <u><em>(7) experience</em></u> with a weedicide. He was a <u><em>(8) planter</em></u> then, working <u><em>(9) on</em></u> a rubber plantation. He had a problem with weeds. The cost of weeding of the <u><em>(10) fields</em></u> by hand was getting <em><u>(11) too</u></em> high. So he used a new, cheap, and effective <u><em>(12) method</em></u>, good old Sodium Arsenate. He sprayed plenty of this <em><u>(13) around</u></em> to kill the weeds. The first thing to <em><u>(14) react</u></em> were the frogs.
