Answer:
r = 9/sin Ф or r = 9 csc Ф
Step-by-step explanation:
The polar form is represented as:
x = r cos Ф and
y = r sin Ф
We are given:
y = 9
Putting value in y = r sin Ф
9 = r sin Ф
=> r = 9/sin Ф
1/sin Ф = csc Ф
or, r = 9 csc Ф
Answer:
C. 61
Step-by-step explanation:
Two sides are equal, so the triangle is an isosceles triangle.
Both base angles are equal.
Angles in a triangle add up to 180 degrees.
58 + x + x = 180
58 + 2x = 180
2x = 122
x = 61
She bought 4 English books and 2 math books
27 x 4 = 108
23 x 2 = 46
108+46=154
Answer: 1 club - Club 2
Step-by-step explanation:
You can find the monthly rates by deducting the cost at 12 months from the cost at 24 months and dividing it by 12.
Club 1 Club 2 Club 3
= (432 - 216) / 12 = (390 - 210) / 12 = (504 - 252) / 12
= $18 = $15 = $21
Multiply these rates by 6 months and any club total cost at 6 month that differs from your answer has a joining fee.
Club 1; Club 2; Club 3
= 18 * 6 = 15 * 6 = 21 * 6
= $108 = $90 = $126
<em>Same as total cost at </em><u><em> Joining fee of $30</em></u><em>; </em> <em>No joining fee as </em>
<em>6 months so no joining 120 - 90 = $30 this is the same </em>
<em>fee. as total cost at 6 </em>
<em> months.</em>
Amount of potatoes that Zoe has = 5 pounds
Quantity of potatoes that Zoe need for each recipe = 5/(3/4)
= 5 * (4/3)
= 20/3
= 6 2/3
From the above deduction, we can conclude that only 6 recipes can be made. The remaining amount of 2/3 will remain unused. I hope the procedure is clear enough for you to understand.
