Answer:
Step-by-step explanation:
We are given that a function
Differentiate w.r.t x
Therefore, intervals
Interval :
x=0
Decreasing function.
Interval:
Substitute x=2
Function increasing.
From given graph we can see that function is negative for the values of x
-2<x<4
Hence, the graph is negative and decreasing for the values of x
The answer is on the paper
Answer:
The value of x is 28°
Step-by-step explanation:
Here, In a given fugue, a = 40°
We know that, A straight angle is an angle equal to 180°
So,
a + 2x + 3x = 180°
40° + 5x = 180°
Subtract 40 from both side
40° - 40° + 5x = 180° - 40°
5x = 140°
Divide by 5 from both side
5x/5 = 140°/5
x = 28°
Thus, The value of x is 28°
<h3 /><h3>
<u>FOR</u><u> </u><u>VERIFICATION</u><u> </u><u>ONLY:</u></h3>
<u>a + 2x + 3x = 180°</u>
40 + 2(28) + 3(28) = 180°
40° + 56° + 84° = 180°
180° = 180°
Hence, L.H.S = R.H.S

Answer:
hello :
the perimeter is : p = 2 ( w + l )
The area is : A= w ×l w : width l : length w ?
2 ( w + l ) = 76
w ×l = 336
you have the system :
w + l = 38 ...(1)
w ×l = 336...(2)
by (1) : l = 38 - w
subst in (2) : w ( 38 - w ) =336
38w - w²= 336
w² - 38w +336 = 0
delta = b² -4ac when : a = 1 and b= -38 c = 336
delta = (-38)² -4(1)(336) = 1444 - 1344 = 100 = 10²
w1 = (38-10)/2 = 14( the shorter sides length)
w2 = (38+10)/2 = 24( refused )
