Answer:
false
Step-by-step explanation:
the formula for the area of a circle is πr^2
π=3.14
r= 1/2 of diameter = 6
3.14 x 6^2
=113.04cm2
I'm not really sure what the question you're asking is, but if you want to know how much would be left, the answer is 19/30 pounds of clay.
The numerator of this function given may be factored out as follows,
x² - 2x - 15 = (x - 5)(x + 3)
Given that the expression x - 5 appears in both the numerator and the denominator, we can cancel them and the new function becomes,
f(x) = x + 3
which is continuous at 5.
Answer:
C. 65
Step-by-step explanation:
Compare to the standard form ...
ax² +bx +c
to find the values of a, b, c. They are ...
a=2, b=3, c=-7
The discriminant is ...
d = b² -4ac
d = (3)² -4(2)(-7) = 9 +56
d = 65 . . . . . . matches choice C
