Answer:

m<B = 141 degrees

Step-by-step explanation:

This shape is a heptagon meaning its angles should have a sum of 900 degrees.

we are given the degrees and we need to ad them up

148+90+120+129+130+142=749

then we subtract 749 from 900 which looks like

900-749=141

from subtracting 749 from 900 we get 141 hence we get our answer that m<B = 141 degrees

PLEASE HELP<br> Find the set A U ∅<br> U={1,2,3,4,5,6}<br> A={3,4,5,6}
nika2105 [10]

The value of the set operation A U ∅ is {3, 4, 5, 6}

<h3>How to evaluate the set operation?</h3>

The elements of the sets are given as:

U = {1, 2, 3, 4, 5, 6}

A = {3, 4, 5, 6}

To calculate the set A U ∅, we use the following illustration

A U ∅ = set A combined with an empty set

This gives

A U ∅ = {3, 4, 5, 6} combined with an empty set

This gives

A U ∅ = {3, 4, 5, 6}

Hence, the value of the set operation A U ∅ is {3, 4, 5, 6}

Step-by-step explanation:

\displaystyle y = Asec(Bx - C) + D

According to this trigonometric function, −C gives you the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL:

\displaystyle Phase\:[Horisontal]\:Shift → \frac{0}{4} = 0 \\ Period → \frac{2}{4}π = \frac{π}{2}

Therefore we have our answer.

Extended Information on the trigonometric function

\displaystyle Vertical\:Shift → D \\ Phase\:[Horisontal]\:Shift → \frac{C}{B} \\ Period → \frac{2}{B}π \\ Amplitude → |A|

NOTE: Sometimes, your <em>vertical shift</em> might tell you to shift your graph below or above the <em>midline</em> where the amplitude is. Moreover, ALL <em>tangent</em>,<em> </em><em>secant</em>, <em>cosecant</em>, and <em>cotangent</em> functions have NO AMPLITUDE.

I am joyous to assist you anytime.

Answer: 1 2/7, 7/9,3/4

Step-by-step explanation: 9/7 you had to make a whole then make the fraction 2/7. 7/9 you literally just had to subtract 8-1 to gt 7 and because the denominator didn't need to change it so that makes it 7/9. And the last one 9/12 well 3 can go into 9 and 12 evenly. For 9 it goes in 3 times and for 12 it goes in 3 to any you get 3/4.
