Plz help me with b,a , and b
solniwko [45]
2A) C is correct.

2B) If x + 13 = 28, solve.
x+13=28\\&#10;x=15
If x = 15 and x + 13 = 28, you can solve it two ways:
1. Plug x into 4x + 26 to get a perimeter of 86, or
2. Redo the equation:
P=2(15)+2(28)\\&#10;P = 30+56\\&#10;P=86

3a. Since the 6z is negative, you want an expression the has 5z - (11z). Answers A and D have that in their answer.
But since the 13 is positive, you want the answer that subtracts the smaller number from the larger. Thus, D is your answer since it subtracts 2 from 15.

3b) You think about this question the same way; 6z is positive, so the smaller number is being subtracted from the larger, meaning that 11z - 5z is what you look for. C and D are the two that have that, so now let's look at the second term.
The 13 is negative, so you want the answer that has 2 - 15. The answer that has that is D.

Hope this helps :D

2. Suppose there are 6 million people in New York City that walk an average of 2.5 miles per day. If we add up all the miles wal
Lunna [17]

Answer:

  • 600 times

Step-by-step explanation:

<h3>Given</h3>

<u>Number of people:</u>

  • 6 million = 6*10^6

<u>Distance to walk:</u>

  • 2.5 miles per day per person

<u>Distance around the Earth</u>

  • 2.5*10^4
<h3>Solution</h3>

<u>Total distance walked:</u>

  • 6*10^6*2.5 = 15*10^6

<u>The ratio of total distance to the distance around the Earth:</u>

  • 15*10^6 / 2.5*10^4 = 6*10^2 = 600 times

Find the exact value of sec theta if csc theta = -4/3 and the terminal side of theta lies in quadrant III
GREYUIT [131]

Answer:

-4 sqrt(7)/7

Step-by-step explanation:

csc theta = -4/3

csc theta = hypotenuse / opposite side

hypotenuse = 4  

opposite  = 3

Using the pythagorean theorem

a^2 + b^2 = c^2

3^2 + b^2 = 4^2

9+b^2 = 16

b^2 = 16-9

b^2 = 7

Taking the square root

sqrt(b^2) = sqrt(7)

b = sqrt(7)

We are in the third quadrant so only tan  and cot are positive

that means the x and y values are "negative"  so a = -3 and b = - sqrt(7)

sec theta = hypotenuse / adjacent

                = 4/ - sqrt(7)

rationalizing  

                   -4 sqrt(7)/ sqrt(7)* sqrt(7)

                = -4 sqrt(7)/7
