base times height divided by 2
8 time 6 is 48 divided by 2 is 24
We have to find the expansion of 
We will use binomial expansion to expand the given expression, which states that the expression 
is expanded as :
Now expanding we get,
So, the variables are 
, 
, 
, ![a^{8} , [tex] ab^{7}](https://tex.z-dn.net/?f=%20a%5E%7B8%7D%20%20%2C%20%5Btex%5D%20ab%5E%7B7%7D%20)
Let cos x = a, then
2a^2 + a - 1 = 0,
solving the quadratic equation, we have:
a = 0.5 or -1.
i.e. cos x = 0.5 or cos x = -1
for cos x = 0.5,
x = pi/3, 2pi - pi/3 = pi/3, 5pi/3
for cos x = -1,
x = pi
therefore, x = pi, pi/3, 5pi/3
Answer: B
Answer:
The number of pipes to be cut from total length of pipe is 10 pipes
Step-by-step explanation:
Given as :
Total length of pipe = l = 7
foot
i.e ' = 
foot
The length of pipe to be cut = l' = 
foot
Let The number of pipes to be cut = n pipes
<u>According to question</u>
The number of pipes to be cut = 
i.e n = 
Or, n = 
Or, n = 
or, n = 5 × 2
∴ n = 10 pipes
So, The number of pipes to be cut = n = 10 pipes
Hence, The number of pipes to be cut from total length of pipe is 10 pipes Answer
Answer:
676π Sq. cm.
Step-by-step explanation:
The line GY is the radius of the circle with G as center and Y is a point on the circle.
Now, GY = 10 cm.
Again, the line XY is the radius of the circle with X as center and Y is a point on the circle.
Now, XY = 16 cm
The two circles touched at point Y,
Therefore, point Y will be on line GX.
Now, GX = GY + YX = 10 + 16 = 26 cm.
Therefore, Marco wants to create a new circle using GX as the radius, then the area of the new circle will be π (26)² Sq. cm. = 676π Sq. cm. (Answer)
