Answer: 8.3 ft

Step-by-step explanation:

Here, The volume of this perfectly spherical balloon is approximately 2361.7 cubic feet.

Since, the volume of a sphere, V= \frac{4}{3} \pi r^3

Where r is the radius of the sphere.

Here V= 2361.7 cubic feet

Therefore, 2361.7=\frac{4}{3} \pi r^3

⇒ r^3= \frac{21\times 2361.7}{88}

⇒r= 563.5875^{1/3}=8.2601344693≈8.3 feet

Thus, the radius of the sphere = 8.3 feet

Separate the x- and y-values with a comma.<br> X=-3+y<br> 26x - 5y = 6
labwork [276]

Answer:

The solution of the given system is (x,y) = (1,4)

Step-by-step explanation:

Here, the given system of equation is:

x  = -3 + y

26 x - 5 y =  6

Now, substitute x  = -3 + y in the second equation , we get

26 x - 5 y =  6  ⇒   26 (-3 + y) - 5 y =  6

or, 26(-3)  + 26(y)  - 5y = 6

⇒ - 78 + 26 y - 5y = 6

⇒   21 y =  84

⇒  y = 84 / 21 = 4   or ,   y =  4

So x  = -3 + y  =  -3 + 4 = 1

Hence, the solution of the given system is (x,y) = (1,4)

Let g(x) = 2x2 - 11x. Find g(-1).<br> A) -13 Eliminate <br> B) -9 <br> C) 0 <br> D) 13
worty [1.4K]

Solution

g(x) = 2x^{2} - 11x

Plugging in x = -1 in g(x), we get

g(-1) = 2(-1)^{2} - 11(-1)

Now we have to simplify it.

g(-1) = 2*1 + 11

g(-1) = 2 + 11

g(-1) = 13

So the answer is D) 13.


Thank you. :)
