Answer:
A
Step-by-step explanation:
From the diagram:
- P(-4,6)→P'(4,6);
- Q(-7,4)→Q'(7,4);
- R(-6,1)→R'(6,1);
- S(-2,1)→S'(2,1);
- T(-1,4)→T'(1,4).
The general rule of this reflection is
(x,y)→(-x,y)
and this is reflection across the y-axis. The y-axis has the equation x=0.
The area is 50.24 cm.
The formula is π·r^2.
The radius is 4 cm, and you square it. 16 cm.
Then you multiply 16 by 3.14 (π). And you get 50.24 cm as the area.
Answer:
y = 12 
Step-by-step explanation:
The standard form of the exponential function is
y = a 
Find a and b by substituting ordered pairs from the table into the equation
Using (0, 12 ), then
12 = a
(
= 1 ), so
a = 12, then
y = 12 
Using (1, 34.8 ) , then
34.8 = 12
( divide both sides by 12 )
b = 2.9
Thus exponential function is
y = 12 
Answer:
Fifteen and six hundredths
Step-by-step explanation:
Answer:
11
Step-by-step explanation:
cross multiply - 2(2x-4) = 3(x=1)
4x - 8 = 3x + 3
4x - 3x = 3 + 8
x = 11
