Answer:
381.51 in^3
Step-by-step explanation:
Volume of a sphere = 4/3 x pi x r^3
r = 9/2 = 4.5
4/3 x 3.14 x 4.5^3 = 381.51 in^3
Answer:
x+3y-6=0
Step-by-step explanation:
given eqn is y=3x-2 which is 3x-y-2=0
the eqn of line perpendicular to given eqn is -x+3y+k=0
it passes through (6,4)
-6+3*4+k=0
or,. -6+12+k=0
or, k= -6
therefore, the eqn of line perpendicular to given eqn is x+3y-6=0
Answer:
x = 7
Step-by-step explanation:
5x-4 = 31
5x = 31+4
5x = 35
x = 7
Answer:
<h2>
</h2><h2><u><em>
the equation is false</em></u></h2>
<u><em></em></u>
Step-by-step explanation:
x - 10+ 9x = - 1 + 10x
-10 + 1 = -x - 9x + 10x
-9 = 0
the equation is false
Standard form is ax^2+bx+c=0
First evaluate the exponent and expand (foil).
y= 3(x^2-4x+4)+1
Then distribute the 3
y= 3x^2-12x+12+1
Combine like terms
y=3x^2-12x+13
Final answer: 3x^2-12x+13=0
