Answer:
I don't know what you wanted, so I graphed it
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 .
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:
The answer is 13, 9 and (-1)
Step-by-step explanation:
<h3><u>Given</u>;</h3>
<h3><u>To </u><u>Find</u>;</h3>
- h(x) = (-2x + 9) when x = (-2), 0 and 5.
For x = (-2)
h(x) = (-2x + 9)
h(-2) = [-2(-2) + 9]
h(-2) = (4 + 9)
h(-2) = 13
For x = 0
h(x) = (-2x + 9)
h(0) = [-2(0) + 9]
h(0) = (0 + 9)
h(0) = 9
For x = 5
h(x) = (-2x + 9)
h(5) = [-2(5) + 9]
h(5) = [(-10) + 9]
h(5) = (-1)
Thus, The answer is 13, 9 and (-1) when x = (-2), 0 and 5 respectively.
Answer:
½pi or 0.5pi units²
Step-by-step explanation:
Area : angle
9pi : 2pi
x : pi/9
9pi/2pi = x/(pi/9)
4.5 × pi/9 = x
x = ½pi or 0.5pi units²
