Identify the situation that involves opposite quantities adding up to zero Climbing up 6 feet and climbing down 4 feet Hiking 10
ivolga24 [154]

9514 1404 393

Answer:

  (b)  Hiking 10 feet due north, then hiking 10 feet due south

Step-by-step explanation:

Any pair of numbers that totals zero will be a pair of opposites. The offered choices are ...

  +6 -4 = 2 . . . not zero

  +10 -10 = 0

  +2 -3 = -1 . . . not zero

  +5 -3 = 2 . . . not zero

Hiking 10 feet due north, then hiking 10 feet due south is a situation involving opposite numbers adding up to zero.

1.In the beautiful place of Sabang. Danao City we can see a lot of Coconut
MrRa [10]

Answer:

A) Number of mango trees

B) Percentage of coconut trees = 60%

Total number of trees = 2230 trees

C)number of mango trees = 40% × 2230

D) 892 mango trees

Step-by-step explanation:

A) What is asked is the number of mango trees

B) We are given;

Percentage of coconut trees = 60%

Total number of trees = 2230 trees

C) Number sentence is defined as when we use an equation or inequality to describe an expression using numbers and signs.

We have percentage of coconut trees = 60%.

Thus, percentage of mango trees = 100% - 60% = 40%

In this case, the number sentence is; number of mango trees = 40% × 2230

D) number of mango trees = 40% × 2230 = 892

Csc (2sin^-1(-12/13))<br> that is 2 times inverse sin of -12/13
german
Answer: -\frac{169}{120}

I'm assuming you mean this:

cosec(2sin^{-1}(\frac{-12}{13}))

Recall what the cosecant function represents. It is the reciprocal of a sine function, and is often written in this form:

\frac{1}{sinx}

So, using the sine relationship:

cosec(2sin^{-1}(\frac{-12}{13})) = \frac{1}{sin(2sin^{-1}(\frac{-12}{13}))}

Let u = sin^{-1}(\frac{-12}{13})
cosec(2sin^{-1}(\frac{-12}{13})) = \frac{1}{sin(2u)}
= \frac{1}{2sinu \cdot cosu}
= \frac{1}{2sin(sin^{-1}(\frac{-12}{13})) \cdot cos(sin^{-1}(\frac{-12}{13}))}
= \frac{1}{\frac{-24}{13} \cdot \sqrt{1 - (\frac{-12}{13})^{2}}}
= \frac{1}{\frac{-24}{13}} \cdot \frac{1}{\sqrt{1 - \frac{144}{169}}}
= -\frac{13}{24} \cdot \frac{1}{\sqrt{\frac{25}{169}}}
= -\frac{13}{24} \cdot \frac{1}{\frac{5}{13}}
= -\frac{13}{24} \cdot \frac{13}{5}
= -\frac{169}{120}
