Answer:
All positive integers less than or equal to 4
Step-by-step explanation:
The domain of the function are all possible values which variable x can take.
Since x is the number of times the root splits, x can take values 1 (1 time splits), 2 (2 times splits), 3 (3 times splits), 4 (4 times splits).
The variable x cannot take negative values because it cannot split -2 times.
The variable x cannot take integer values greater than 4, because this type of plant root splits 4 times while growing in the ground.
Hence, the domain of the function f(x) is all positive integers less than or equal to 4.
Answer:
c. 9/12
Step by step explanation.
Given: sin = 9/15
and,
thus, find adj. side
by using Pythagoras theorem
then,
let adj. side be a^
thus,
adj. side is 12
then,
tan of the angle = 9/12
Answer:
C. (-1, 3)
Step-by-step explanation:
Label the 2 equations:
5y= 7x +22 -----(1)
x= -6y +17 -----(2)
Substitute (2) into (1):
5y= 7(-6y +17) +22
5y= -42y +119 +22 <em>(</em><em>Expand</em><em> </em><em>bracket</em><em>)</em>
5y= -42y +141 <em>(</em><em>Simplify</em><em>)</em>
42y +5y= 141 <em>(</em><em>+</em><em>42y</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
47y= 141
y= 141 ÷47 <em>(</em><em>÷</em><em>4</em><em>7</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
y= 3
Substitute y= 3 into (2):
x= -6(3) +17
x= -18 +17
x= -1
Thus, the solution is (-1, 3).
2y - 3y + y = 0
-y + y = 0
0 = 0
Hence, y has infinite possibilities of value since the equation is true without there being any use of y in it.
Hence, y could be any value.<span />
