Answer:
62% and 161.29%
Step-by-step explanation:
Given that the percentage of adult height attained by girls who are x years old can be modeled by
, where
x represents the girl's age (from 5 to 15) and
f(x) represents the percentage of her adult height
A) When age =5, we have x=5
So height when age is 5 is 62 %
B) The approximate of her adult height is
Answer:
AC = 18
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos30° = 
, then
cos30° = 
= 
= 
= ( cross- multiply )
2 AC = 12
× = 12 × 3 = 36 ( divide both sides by 2 )
AC = 18
Step-by-step explanation:
a. y=mx+c
m = rise/run
3/2=m
1.5=m
b. y=1.5x+3
c. y int. x=0 x int. y=0
y=1.5(0)+3 0= 1.5x+3
y= 3 -3=1.5×
1.5x/1.5=-3/1.5
x= 2
d. y-y1 =m(x-x1)
y-3=1.5(×-2)
y-3 =1.5x-3
y-3+3=1.5x-3+3
y=1.5x +0
y int =3 x int =2
