12.56 cubic inches
Step-by-step explanation:
Volume of a cone= π r² h/3
3.14*2*2*3/3
3.14*4*3/3
12.56*3/3
=12.56 cubic inches
Answer:
343,000
Step-by-step explanation:
Imagine there are a bunch of zeros to the right of the thousandths decimal place. If the 10 is raised to the fifth power, you want to move the decimal place to the right 5 times. This makes the new number 343,000. Since there are only 3 sig figs in the original number, there would be no decimal place in the standard form.
Answer: d = 63
Explanation:
d/7 + (-59) = -50
d/7 - 59 = -50
d/7 = -50 + 59
d/7 = 9
d = 9 x 7
d = 63
Answer:
Step-by-step explanation:
<h2><u>Given Expression</u> :-</h2>
<h2><u>Steps to factorise</u> :-</h2>
- Write the number in the exponential form with an exponent of 2
- Using a²-b² = (a-b)(a+b), factor the expression.

Given the function f (x) = 3x, find the value of f-1 (81).
For this case, the first thing you should do is rewrite the function.
We have then:
y = 3 ^ x
From here, we clear the value of x:
log3 (y) = log3 (3 ^ x)
log3 (y) = x
Then, we rewrite the function again:
f (x) ^ - 1 = log3 (x)
Now, we evaluate the inverse function for x = 81:
f (81) ^ - 1 = log3 (81)
f (x) ^ - 1 = 4
Answer:
the value of f-1 (81) is:
f (x) ^ - 1 = 4
