17+(-4)-4/5j-2/5j+6​

Mathematics
1 answer:
Snowcat [4.5K]3 years ago
7 0

Answer:

19 - (6/5)j

Step-by-step explanation:

In this expression we have addition, subtraction and multiplication.

According to order of operations rules, mult. and div. must be carried out before add. or subt.

Therefore, we begin with 17+(-4), which becomes 17 - 4, or 13.

Next we see -4/5j, by which I assume you mean -4/5 * j.

Summarizing what we have so far:

13  - (4/5)j - 2/5j + 6

Combining the j terms, we get

13 - (6/5)j + 6, which collapses to 19 - (6/5)j.

Solve the equation 2cosA = 3tanA
zavuch27 [327]
\bf sin^2(\theta)+cos^2(\theta)=1\implies cos^2(\theta)=1-sin^2(\theta)&#10;\\\\\\&#10;tan(\theta)=\cfrac{sin(\theta)}{cos(\theta)}\\\\&#10;-----------------------------\\\\&#10;&#10;2cos(A)=3tan(A)\implies 2cos(A)=3\cfrac{sin(A)}{cos(A)}&#10;\\\\\\&#10;2cos^2(A)=3sin(A)\implies 2[1-sin^2(A)]=3sin(A)&#10;\\\\\\&#10;2-2sin^2(A)=3sin(A)\implies 2sin^2(A)+3sin(A)-2

\bf \\\\\\&#10;0=[2sin(A)-1][sin(A)+2]\implies &#10;\begin{cases}&#10;0=2sin(A)-1\\&#10;1=2sin(A)\\&#10;\frac{1}{2}=sin(A)\\\\&#10;sin^{-1}\left( \frac{1}{2} \right)=\measuredangle A\\\\&#10;\frac{\pi }{6},\frac{5\pi }{6}\\&#10;----------\\&#10;0=sin(A)+2\\&#10;-2=sin(A)&#10;\end{cases}

now, as far as the second case....well, sine of anything is within the range of -1 or 1, so -1 < sin(A) < 1

now, we have -2 = sin(A), which simply is out of range for a valid sine, so there's no angle with such sine

so, only the first case are the valid angles for A

A peculiar six-sided die has uneven faces. In particular, the faces showing 1 or 6 are 1 × 1.5 inches, the faces showing 2 or 5
sveta [45]

Answer:

0.2216

Step-by-step explanation:

The probability of a particular face coming up is proportional to its area.

Hence, we first calculate the areas.

For 1 or 6, area = 1 × 1.5 = 1.5 in²

For 2 or 5, area = 1 × 0.4 = 0.4 in²

For 3 or 4, area = 0.4 × 1.5 = 0.6 in²

Total surface area of the die = 2(1.5) + 2(0.4) + 2(0.6) = 5 in²

Since probability is proportional to area of a particular face, we calculate the probabilities from the ratio of each surface area to the total surface area.

Probability of a 1 showing up = 1.5/5 = 0.30

Probability of a 2 showing up = 0.4/5 = 0.08

Probability of a 3 showing up = 0.6/5 = 0.12

Probability of a 4 showing up = 0.6/5 = 0.12

Probability of a 5 showing up = 0.4/5 = 0.08

Probability of a 6 showing up = 1.5/5 = 0.30

Probability of doubles with the die is a sum of the probabilities of all the possible doubles with the die.

Probability of a 1 double = 0.3 × 0.3 = 0.09

Probability of a 2 double = 0.08 × 0.08 = 0.0064

Probability of a 3 double = 0.12 × 0.12 = 0.0144

Probability of a 4 double = 0.12 × 0.12 = 0.0144

Probability of a 5 double = 0.08 × 0.08 = 0.0064

Probability of a 6 double = 0.3 × 0.3 = 0.09

Probability of a double with the die = (0.09 + 0.0064 + 0.0144 + 0.0144 + 0.0064 + 0.09) = 0.2216
