Answer:
(b) 36.56 ft
Step-by-step explanation:
The perimeter is the total of the circumference of a 4 ft circle and two lengths that are 12 ft.
The circumference is given by ...
C = πd
C = (3.14)(4 ft) = 12.56 ft
Adding the 24 ft of straight sections, we find the total perimeter to be ...
P = 12 + 12 + 12.56 = 36.56 . . . feet
Answer:
Step-by-step explanation:
As the equation is x+y=8 , dividing each term by 8 , we get. x8+y8=1. and hence, intercepts formed by the line on x -axis is 8 and on y -axis too it is 8 . Hence mark the intercepts 8 on each axis and join them to draw the graph of x+y=8
Answer:
1.5 hours
Step-by-step explanation:
Calculate speed using
time = 
= 
= 1.5 hours or 1 hour 30 mins
We know that
in a quadratic equation of the form
ax²+bx+c=0
the discriminant is
D=b²-4ac
if D> 0 <span>then there are two real number solutions
if D=0 </span><span>then there's only one real number solution.
if D< 0 </span><span>then there are two complex number solutions
in this problem
we have
</span>3x²<span>-6x+3=0
a=3
b=-6
c=3
so
</span>D=b²-4ac-----> D=(-6)²-4*(3*3)----->D=36-36------->D=0
therefore
there's only one real number solution
