1) When you rewrite the equation as
.. y = kx^2
The value of k is 3/0.1 = 30.
2) When you rewrite the equation as
.. y = kx^2
The value of k is 6/10 = 0.6.
3) f(x) = kx^2
.. k = f(x)/x^2 = 96/4^2 = f(2)/2^2
.. f(2) = 96(2/4)^2
.. f(2) = 24
4) g(x) = kx^2
.. 98 = k*7^2 = 49k
.. k = 98/49 = 2
g(x) = 2x^2
Multiply both sides by 5
4x^2=10x-4
divide both sides by 2
2x^2=5x-2
minus 5x from both sides and add 2 to both sides
2x^2-5x+2=0
use quadratic formula
for
ax^2+bx+c=0
x=
given
2x^2-5x+2=0
a=2
b=-5
c=2
x=
x=
x=
x=
x=(5+3)/4 or (5-3)/4
x=8/4 or 2/4
x=2 or 1/2
3rd option is correct
Since you posted this question twice , im gonna put the same answer twice :) so for a mother ages 28 , there is a chance of 1 in 1000 , but at the age of 38 there is a chance of 1 in 200 . to work out how many times more likely it is for the 38 year old to give birth to a child with down syndrome is to divide 1000 by 200 and this gives us 5 . so the 38 year old is 5 times more likely to give birth to a child with down syndrome than a 28 year old :)
Answer:
It is not true
Step-by-step explanation:
(63 ÷ 7)2 = 18
39 ÷ 3 = 13
Hence, the statement is false
Answer:
Snow is needed to make the snowman is= 155.04 cubic feet
Step-by-step explanation:
Given the bottom ball is 3 feet across.
The volume of snow to make the bottom ball=
cubic feet
The middle ball is 2 feet across.
The volume of snow to make the middle ball=
cubic feet
The top ball is 1 feet across.
The volume of snow to make the top ball=
cubic feet
Snow is needed to make the snowman is
() cubic feet
cubic feet
cubic feet
=155.04 cubic feet
