Answer:
B
Step-by-step explanation:
f(x)=6^x has a full, positive number that is greater than one. The others are all fractions, and either are almost straight or decrease. If you graph all four, you can also see that f(x)=6^x is the only function that is increasing.
Hope this helped.
Answer:
<h3>x is 4 more than thrice of y</h3>
Answer:
a. x = 9
b. GH = 30; GK = 20
Step-by-step explanation:
An angle bisector in a triangle divides the sides proportionally.
<h3>a.</h3>
In this triangle, that means ...
(3x +3)/18 = (3x -7)/12
2(3x +3) = 3(3x -7) . . . . . . . multiply by 36
6x +6 = 9x -21 . . . . . . . . . eliminate parentheses
27 = 3x . . . . . . . . . . . . . . add 21 -6x
x = 9 . . . . . . . . . . . . . . . divide by 3
__
<h3>b.</h3>
The segment lengths are found by substituting the value of 3x in each of the given expressions:
GH = 3x +3 = 27 +3 = 30
GK = 3x -7 = 27 -7 = 20
Answer:
1. 23.55 in
2. 102.36 mm
Step-by-step explanation:
The circumference of a circle is calculated by the formula: 
, where d is the diameter and r is the radius.
We can use this to answer both problems.
1. Since the diameter is 7.5 inches, then d = 7.5. Substitute this into the equation: 
. So, the circumference is 23.55 inches.
2. Here, the radius is 16.3 mm, so r = 16.3. Substitute this into the equation: 
. So, the circumference is 102.36 mm.
Hope this helps!
