Answer:
For question 26 the answer is ( 9^210 )
For question 27 the answer is ( 24 )
Step-by-step explanation:
For question number 26: try on the scientific calculator the equation you have pictured it will give you a very long number beginning with 《 2459953978》
Then put the the 9^210 on the calculator and click ( =) if it didn't work try clicking S》D then you will get the same long number Count at least the first 6 numbers for assurance
For question number 27 :The volume of a right cone is given by
[tex]v = \frac{1}{3} \pi \ \: {r}^{2} h[/tex]
Here, you only know the value of one of the variables, V, so you'll need to use the information in the question to somehow write r and h in terms
If the cone is three times as wide at the base as it is tall, then call the diameter 3x and the height of the cone one-third of that, or x. The volume formula calls for the radius, which is half the diameter, or
[tex] \frac{3x}{2} [/tex]
Substitute these values into the formula and solve for x:
[tex]384\pi = \frac{1}{3} \pi {( \frac{3}{2}\pi) }^{2} x \\ 384 = ( \frac{1}{3} )( \frac{9}{4} {x}^{2} )x \\ 384 = \frac{3}{4} {x}^{3 } \\ 512 = {x}^{3 } \\ \sqrt[3]{512} = x \\ 8 = x \\ [/tex]
The question asks for the diameter of the base, which is 3x = 3(8) = 24.
