Answer:
-2x² - 8x - 15
Step-by-step explanation:
-(2x² + 4x + 11) + (-4)
-2x² - 8x - 11 - 4
-2x² - 8x - 15
Answer:
18
Step-by-step explanation:
1. 6x6=36
2. 8+36=44
3. 44/11=4
4. 7x2=14
5. 4+14=18
Answer:
Cos 74°= Sin 16°
Sin 20°= Cos 70°
Sin A°=Cos (90°- A°)
Step-by-step explanation:
This is because the three pairs are complementary i.e they add up to 90° and in trigonometric ratios, complementary ratios are equal.
Answer:
g(x) = x² - 4 is already in form of a variable, I.e., x
g(4x) takes another variable, I.e., 4x
Same as before, 4x takes over x:
=> g(4x) = (4x)² - 4
- <em>(</em><em>ax</em><em>)</em><em>²</em><em> </em><em>=</em><em> </em><em>a</em><em>²</em><em>x</em><em>²</em><em>,</em><em> </em><em>where</em><em> </em><em>a</em><em> </em><em>is</em><em> </em><em>some</em><em> </em><em>arbitrary</em><em> </em><em>constant</em><em>.</em><em> </em>
<h3><u>Answer</u><u>:</u> </h3>
=> g(4x) = 16x² - 4
OR
=> g(4x) = 4{4x² - 1}
Response:
Personally, I would save up and pay for the computer. If I need the computer right away or for a good reason, yes I will use a credit card to buy the computer.
On the other hand, if I don't need it at the moment, I will save up to buy it later and would probably save anyway because it's easier than stacking up on my credit card depending on how much I use my credit card.
(This was a quickly made response, adjust it anyway you would like and if it doesn't fit the question than it is perfectly OK to not use it!)
