1. You will have to find the height first which could be done by using pythagoras theorem
split the 12 by half giving 6
a^2 = b^2 + c^2
13^2 = 6^2+c^2
169 = 36+c^2
c^2=169-36
c^2=133
c=sqrt133
c= 11.53
area of triangle
1/2 x b x h
1/2 x 6 x 11.53
34.59
34.5(3 sf)
Answer:
a
Step-by-step explanation:
did the math :)
brainliest pls!
Answer:
21) y/4=3
multiply 4 to each side
y = 12
22) y/6=7
multiply 6 to each side
y = 42
For 23 - 26 its the same prosses as the first two
Answer:
y = 4. 
Step-by-step explanation:
For an exponential function in the form
y = a
Use ordered pairs from the table to find a and b
Using (0, 4 ), then
4 = a 
( note = 1 ), thus
a = 4
y = 4
Using (1, 12 ), then
12 = 4 
= 4b ( divide both sides by 4 )
b = 3
Thus
y = 4 . ← exponential equation
