Answer:

Step-by-step explanation:

f'(x)=-2x+7

f(x) is decreasing if '(x)<0

so -2x+7<0

or 7<2x

or 2x>7

or x>7/2

including end points f(x) is decreasing in [3/2,∞)

Find the missing angles.
8_murik_8 [283]

Answer:

<em>From left to right: 54 deg, 51 deg, 47 deg</em>

Step-by-step explanation:

From the bottom right triangle:

105 + 28 + x = 180

x + 133 = 180

x = 47

The lower right triangle has angles measuring 28, 105 and 47.

The lower unknown angle of the upper right triangle is vertical to the 47 deg angle, so it also measures 47 deg.

Now we calculate the upper unknown angle of the upper triangle.

82 + 47 + y = 180

y + 129 = 180

y = 51

One angle forms a linear pair with the 105-deg angle. It measures

180 - 105 = 75.

The large left triangle has angles 75 deg, 51 deg, and the unkown angle at the left.

z + 51 + 75 = 180

z + 126 = 180

z = 54

Answer:

A  40

Step-by-step explanation:

We can find angle K

J + K + L = 180  The angles of a triangle add to 180

50 + K + 90 =180

140 +K = 180

Subtract 140 from each side

140-140 + K = 180-140

K = 40

Since the triangles are congruent

J = P

K = N

L = M

We want to find N

K = N = 40

K = N
