Answer:
(f-1)
Step-by-step explanation:
If you substitute a for (f-1) you get the expression...
The number of hydrogen atoms are 304
<em><u>Solution:</u></em>
Given that a water molecule is made up of three atoms
Number of atoms in water molecule = 3 atoms
1/3 of the atoms are oxygen and the remaining Adams are hydrogen
There are 114 water molecules
8/3 of water molecule is hydrogen
<em><u>Therefore, number of hydrogen atoms is given as:</u></em>
Thus number of hydrogen atoms are 304
<em>Answer: y=2/3x-2</em>

<em>Step-by-step explanation:</em>
<em>Slope intercept form is: y=mx+b</em>
<em>m=slope</em>
<em>b= y-intercept</em>
<em>slope is </em><em>2/3</em>
Answer:
Step-by-step explanation:
For Question 3, we are simply taking an input for the function, as a value of x and solving the equation. For part a, we substitute 3/14 into the first function, and solve it:
f(x) = 7(3/14) + 2
f(x) = 21/14 + 2
f(x) = 49/14
f(x) = 7/2
For part b, we take the input of -3 into the second function and solve the equation:
h(x) = 4(-3)^2
h(x) = 4(9)
h(x) = 36
For Question 4, we are simply solving this equation by isolating the x variable. First, we simplify the equation to 4-5x+15+2x = -2 and simplify this again to -3x+19 = -2. Now, we can subtract 19 from both sides of the equation to get -3x = -21. Lastly, we isolate the x variable by dividing both sides of this equation by -3, to get x = 7.
Answer:
B. x = 7, y = 4√2
Step-by-step explanation:
Drop a vertical from the upper left corner
This creates a rectangle and a 45-45-90 triangle
The bottom of the rectangle is 3
The legs of the triangle are 4
Therefor
x = 4 + 3
x = 7
For a 45-45-90 triangle
the hypotenuse = leg * √2
y = 4√2
