Answer:
f(5) = 5
Step-by-step explanation:
To evaluate f(5) , substitute x = 5 into f(x), that is
f(5) = 5² - 20 = 25 - 20 = 5
So if you mean 6^3 times x is 104
6^3x = 105
216x = 105
x= 105/216
x= 0.468111111111111111111111111111111
Answer:

Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- The sum of two numbers is 52.
- The product of the numbers is 4 .
And we need to find the sum of reciprocals of the numbers. For that let us assume that the numbers are
.
<u>According</u><u> to</u><u> </u><u>1</u><u>s</u><u>t</u><u> </u><u>condition</u><u> </u><u>:</u><u>-</u><u> </u>
Now expressing this equation by keeping only one variable on one side as ,
<u>According</u><u> to</u><u> </u><u>2</u><u>n</u><u>d</u><u> </u><u>condition</u><u> </u><u>:</u><u>-</u>
- Now solve this quadratic equation.
On solving the equation using quadratic Formula we will get the value of y as ,
- Note that the sum of x and y is 52 .So in order to find the value of x we will subtract 26±4√42 from 52 and we will get the value of x same as y .
![\implies x = 52 - 26\pm 4\sqrt{42} = 26\pm 4\sqrt{42}](https://tex.z-dn.net/?f=%5Cimplies%20x%20%3D%2052%20-%2026%5Cpm%204%5Csqrt%7B42%7D%20%3D%2026%5Cpm%204%5Csqrt%7B42%7D)
Now we need to find out the sum of reciprocal of the two numbers . That will be ,
<u>Hence</u><u> the</u><u> </u><u>sum </u><u>of</u><u> </u><u>their </u><u>reciprocals </u><u>is </u><u>1</u><u>3</u><u> </u><u>.</u>
Answer:
5x
Step-by-step explanation:
If x is the number of waffle cones sold, the number of cake cones sold is five times that number, or 5x.
