Answer:
2√2 / 3 (first answer choice)
Step-by-step explanation:
If tan Ф < 0, then Ф must be in either Quadrant II or Quadrant IV.
If sin Ф = +1/3, then Ф (for this problem) is in Quadrant II.
Remembering that sin Ф = opp / hyp = 1 / 3, we use the Pythagorean Theorem to find the adj side:
adj² + 1² = 3², or
adj² + 1 = 9, or adj² = 8. Since Ф is in Quadrant II, adj is negative.
The value of cos Ф = adj / hyp = √8 / 3 = 2√2 / 3
<u>Answer:</u>
She paid 26.35 for something that would usually be 31 dollars. The percentage discount she got is 15%
<u>Solution:</u>
A lady paid $26.35 for something that is usually $31, so she got a discount for the product.
Now, we have been asked to find out how much percentage discount she got.
To do that we first have to check how many dollars she got off the product.
To do so we have to subtract the discounted price from the initial price.
Therefore we get:
31 - 26.35 = 4.65
To find the percentage discount we need to do the following

Therefore she got a discount of 15%
$85.20/6= $14.20/pair is the answer because unit price equals cost/pairs

so... if you notice, the vertex is at h,k and that'd be the origin, 0,0
so...since the directrix is "p" units from the vertex, so it'd be 2 units from 0,0
now, the parabola has an equation with a positive leading term's coefficient, namely the 1/8 is positive, thus, the parabola is opening upwards, and the directrix is "outside" the parabola, so is below the vertex
that puts the directrix 2 units below 0,0
y = -2
Answer:
<em>equation=</em>35+6.95h=c
5 hours= $69.75
6 hours= 76.7
7 hours= 83.65
8 hours= 90.6
Step-by-step explanation:
the equation is found by adding 35 (the cost of the machine) and 6.95 times how many hours. To find the hours after 5 just add 6.95 every time.
