Answer:

B & C

Step-by-step explanation:

Supplementary means it equals to the sum of 180.

a) 30 + 60 + 60 = 150

It is less than 180.

b) 45 + 45 + 90 = 180.

This is a possible answer.

c) 72 + 28 + 80 = 180

This is a possible answer.

d) 25 + 75 + 100 = 200

This is greater than 180.

e) 180 + 180 + 180 = 540

This is greater than 180.

Answer:

Notice the only sets that sum to 180° are the first, fifth, sixth and eighth pairs. Only those pairs are supplementary angles.

...

Identify the ones that are supplementary:

175° and 5° 5 °

137° and 93° 93 °

60° and 60° and 60° 60 °

26° and 116° 116 °

90° and 90° 90 °

85° and 95° 95 °

150° and 31° ...

100° and 80°

Answer:

Step-by-step explanation:

60 x²-132x+24=12[5x²-11x+2]

=12[5x²-10x-x+2]

=12[5x(x-2)-1(x-2)]

=12(x-2)(5x-1)

Scalcet8 4. 2. 26. suppose that 2 ≤ f '(x) ≤ 4 for all values of x. what are the minimum and maximum possible values of f(4) − f
ziro4ka [17]

The minimum value of f(4) - f(1) is <u>6</u>.

The maximum value of f(4) - f(1) is <u>12</u>.

In the question, we are given that, 2 ≤ f'(x) ≤ 4 for all values of x.

Taking the given inequality as (i).

We are asked to find the minimum and maximum possible values of f(4) - f(1).

We multiply (i) by dx throughout, to get:

4dx ≤ f'(x)dx ≤ 5dx.

To find this, we integrate (i) in the definite interval [4, 1] with respect to dx, to get:

\int_{1}^{4}2dx \leq \int_{1}^{4}f'(x)dx \leq \int_{1}^{4}4dx\\\Rightarrow [2x]_{1}^{4} \leq [f(x)]_{1}^{4} \leq [4x]_{1}^{4}\\\Rightarrow 2*4 - 2*1 \leq f(4)-f(1) \leq 4*4 - 4*1\\\Rightarrow 6 \leq f(4) -f(1) \leq 12

Thus, the minimum value of f(4) - f(1) is 6.

The maximum value of f(4) - f(1) is 12.
