Answer:2x/5-7+9x/2
Step-by-step explanation:
Alright the radius as shown is 11 yd.
The equation for circumference is 2*pi*r
We can do 3.141 as an estimate.
For this the equation would be 2*3.141*11
We get approximately 69.102. Since we are rounding to the nearest tenth it’s just 69.1
See the attached figure to understand the problem
we know that
<span>the median to the base is the segment BD
the base AC is 15 in
Area=75 in</span>²<span>
Area=AC*BD/2---------> BD=(Area*2)/AC---------> BD=</span>(75*2)/15
BD=10 in
the answer is BD=10 in
First, let's find the scale of the smaller to the bigger triangle:
6:6+4 = 6:10 = 3:5
3/5 = x/2
6 = 5x
x = 6/5
The derivative of :
y = ( 2 x - 7 )³ - we will use the chain rule :
y = u³
y` = 3 u² · u`
y` = 3 ( 2 x - 7 )² · ( 2 x - 7 ) `
y ` = 3 ( 2 x - 7 )² · 2
y ` = 6 ( 2 x - 7 )²
