Answer:
a. y=25/9(x^2)
b. y=44.44
c. x=1.8
Step-by-step explanation:
y=kx^2
a)
y=k*x^2
x=3 y=25
25=k*3^2
25=k*9
25=9k
k=25/9
y=25/9(x^2)
b)
when x=4, y=?
y=25/9(x^2)
y=25/9(4^2)
=25/9(16)
=400/9
=44.44
y=44.44
c)
x=? y=9
y=25/9(x^2)
9=25/9x^2
x^2=9÷25/9
=9×9/25
x^2=81/25
x=√81/25
=9/5
x=1.8
Answer:
1/3 = 0.333
You can use a calculator and it should come out into a decimal.
Note:
/ = divide
Answer:
16.5 m
Step-by-step explanation:
The triangle shown in the figure is a right triangle, so we can use the Pythagoreas Theorem.
a² + b² = c²
a² + 32² = 36²
a² + 1024 = 1296
a² = 272
a = √272
a = 16.5
Answer: 16.5 m
