I think it is the 3rd one but I might be wrong...
Answer: p(-3)=18
Step-by-step explanation:
To find p(-3), you plug -3 into p(x) and solve.
p(-3)=(-3)²-3(-3) [exponent]
p(-3)=9-3(-3) [multiply]
p(-3)=9+9 [add]
p(-3)=18
Now we found that p(-3)=18.
Answer:
It would be 54.
Step-by-step explanation:
It would be 2 times 2, which is four, and then you would add by 50.
2 x 2 = 4
4 + 50 = 54
So, it will not be 100, it will be 54.
A percentage is a way to describe a part of a whole. The regular selling price of the computer notebook will be $937.5.
<h3>What are Percentages?</h3>
A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Let the selling price of the computer notebook be represented by x.
Now, if Sara buys the computer this week, the selling price of the computer will be (100%-16%)x = 0.84x.
Also, the saving she made by buying this week will be $150, therefore, we can write,
x-0.84x = $150
0.16x = $150
x = 937.5
Hence, the regular selling price of the computer notebook will be $937.5.

Let a =70° and b= 10° (and a-b=70-10 =60)
We have the following trigonometric identity:
sin(a-b) = sin(a).cos(b)-sin(b).cos(a) OR:
sin(70-10) = sin70.cos10 - sin10.cos70
But sin(70-10) = sin(60) and we know that sin(60°) =(√3)/2
