Step-by-step explanation:
you have to use this
u/v=u'×v-v'×u/v²
0×(1+cosy)-(-1×-siny)/(1+cosy)²
-siny/(1+cosy)²
hopefully its correct
4(a + 2) + 9 = 5
to solve this problem lets solve this step by step
Step 1 - lets solve this part of problem 4(a + 2 )
by using distributive property we get,
4a + 8 + 9 = 5
Step 2 - adding the like terms
4a + 17 = 5
Step 3 - subtracting 17 from both sides
4a + 17 - 17 = 5 - 17
4a = -12
Step 4 - dividing both sides by 4
a = -3
So our final answer is a = -3
Hope this helps you :)
-6a - 4a + 7a = -10a + 7a = -3a, that isn't 5a;
b. False
Answer:
V = 8,181.23 ![cm^{3}](https://tex.z-dn.net/?f=cm%5E%7B3%7D)
Step-by-step explanation:
Unfortunately, we are not given any answer choices to choose from but using the information provided we can find the actual volume of the basketball. A basketball is made in the shape of a sphere and the formula for the volume of a sphere is the following...
V = ![\frac{4}{3} * \pi * r^{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%20%2A%20%5Cpi%20%20%2A%20r%5E%7B3%7D)
radius of a circle/sphere is half of it's diameter. Since we are provided the diameter size we simply divide it by 2 which would give us 12.5cm. Now we simply plug this value into the formula and solve for V.
V = ![\frac{4}{3} * \pi * 12.5^{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%20%2A%20%5Cpi%20%20%2A%2012.5%5E%7B3%7D)
V = ![\frac{4}{3} * \pi * 1953.125](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%20%20%2A%20%5Cpi%20%20%2A%201953.125)
V = 8,181.23 ![cm^{3}](https://tex.z-dn.net/?f=cm%5E%7B3%7D)
I'm suggesting this was supposed to be the table:
A survey was conducted of students at a high school and at a college to determine students' favorite subjects. The results are shown in the table.
History Math Science Total
High School 80 50 70 200
College 70
60
70 200
Total 150 110 140 400
What percentage of the students are college students that prefer history?
O A. 17.5%
OB. 35%
OC. 37.5%
D. 46.7%
E 75%
