I would say 12 because all of the number that were presented to be they all equal 12 because 12x4=48 and 12x7=84 and 12x8=96
Let <em>f(x)</em> = <em>ax</em> ² + <em>bx</em> + <em>c</em>. Then
<em>f '(x)</em> = 2<em>ax</em> + <em>b</em>
<em>f ''(x)</em> = 2<em>a</em>
<em />
<em>f</em> (-3) = -18, so
9<em>a</em> - 3<em>b</em> + <em>c</em> = -18
<em>f '</em> (-3) = 16, so
-6<em>a</em> + <em>b</em> = 16
<em>f ''</em> (-3) = -6, so
2<em>a</em> = -6
Then <em>a</em> = -3, <em>b</em> = -2, and <em>c</em> = 3, so that
<em>f(x)</em> = -3<em>x</em> ² - 2<em>x</em> + 3
Answer:
935
Step-by-step explanation:
Let's solve the rectangle first. We are dividing this figure into two sepreate shapes, can you see that?
-
1/2*B*h
630
-
Now for the other shape.
Volume = 315
630+315=935
Answer:
$7
Step-by-step explanation:
a) First let's organize the information:
The cage cost $40
two bowls cost the same
the total was $54
b) Put it as an equation
40+x+x= 54
c) we will subtract 54-40 and get 14
d) divide 14 by 2 and get 7 for the cost of each bowl.
Hope you understand it ;)
Answer: B
Step-by-step explanation:
Since this is a 30-60-90 triangle, b=8(sqrt3) = 8sqrt3.
By the same logic, c=8(2)=16.
