Answer:
He can make it with Max's audio goods
44.575 miles < 45 miles
Step-by-step explanation:
The angle of the truck driver = 180 - (60 + 69) = 51°
By using sin Rule:
40/sin51 = Max's auto goods/sin60 = Jimmy's car supply/sin69
∴ Max's auto goods = 40(sin60)/sin51 = 44.575 miles
∴ Jimmy's car supply = 40sin(69)/sin51 = 48.052 miles
∵ The truck driver can travel another 45 miles
∴ He can make it with Max's audio goods because 44.575 < 45
Answer:
Step-by-step explanation
Hello!
3x/4 + 6=42
3x/4=42-6 = 36
3x = 36*4
3x = 144
x= 144/3 =48
3/4 of 48 = (48*3) / 4 =36
36+6=42
the original number is 48

Let
x ----------> the height of the whole poster
<span>y ----------> the </span>width<span> of the whole poster
</span>
We need
to minimize the area A=x*y
we know that
(x-4)*(y-2)=722
(y-2)=722/(x-4)
(y)=[722/(x-4)]+2
so
A(x)=x*y--------->A(x)=x*{[722/(x-4)]+2}
Need to minimize this function over x > 4
find the derivative------> A1 (x)
A1(x)=2*[8x²-8x-1428]/[(x-4)²]
for A1(x)=0
8x²-8x-1428=0
using a graph tool
gives x=13.87 in
(y)=[722/(x-4)]+2
y=[2x+714]/[x-4]-----> y=[2*13.87+714]/[13.87-4]-----> y=75.15 in
the answer is
<span>the dimensions of the poster will be
</span>the height of the whole poster is 13.87 in
the width of the whole poster is 75.15 in
