A)x=2pi/3 and x=-2pi/3

Step-by-step explanation:

The function [tex]y=\frac{5}{3}tan(\frac{3}{4}x)[/tex] has vertical asymptotes in the values where the tan(a) has vertical asymptotes.

we know that tan(a) has vertical asymptotes in [tex]a=\frac{\pi }{2}[/tex] and  [tex]a=\frac{-\pi }{2}[/tex], if we made [tex]a=\frac{3x}{4}[/tex] and solve for x, we get:

for [tex]a=\frac{\pi }{2}[/tex]

[tex]\frac{\pi }{2} =\frac{3x}{4}\\x = \frac{2\pi }{3}[/tex]

for [tex]a=\frac{-\pi }{2}[/tex]

[tex]\frac{-\pi }{2} =\frac{3x}{4}\\x = \frac{-2\pi }{3}[/tex]

Finally, the function [tex]y=\frac{5}{3}tan(\frac{3}{4}x)[/tex] has vertical asymptotes in the values x=2pi/3 and x=-2pi/3

Answer:

For Triangles:

To find remaining angles, implying that you have angles already given to you, you would mark your unknown angle as a variable, x per say, then you would add together the angles that you do have and you would subtract that by 180 degrees because all triangles angles sum up to 180 degrees. So when you subtract that you should be able to find your unknown angle.

Answer:

[tex]r \approx 2.41\%[/tex]

Step-by-step explanation:

The computation of the approximate new interest rate is shown below:

As we know that there are four quarters in a year so

The new equation is

[tex]A = 250(1 + r)^{4t}[/tex]

Now to determine the value of interest rate,i.e r, so place this to the first equation.

So,

[tex]250(1.1)^{t} = 250(1 + r)^{4t}[/tex]

[tex]1.1^{t} = (1 + r)^{4t}[/tex]

1.1 = (1 + r)^4

[tex]\sqrt[4]{1.1} = 1 + r[/tex]

[tex]r = -1 + \sqrt[4]{1.1}[/tex]

[tex]r \approx 0.0241[/tex]

[tex]r \approx 2.41\%[/tex]

We simply applied the above formula so that the interest rate could come

Answer:

884,375

Step-by-step explanation:

The first digit can't be 0, so there are 9×10⁵ = 900,000 possible six-digit numbers.

Of those, the number of six-digit numbers that have only odd digits is 5⁶ = 15,625.

Numbers with at least one even digit are all numbers that don't have only odd digits.  So the number of six-digit numbers with at least one even digit is:

900,000 − 15,625 = 884,375

Answer:

C. Stacy

Step-by-step explanation:

One way to compare is to convert all the fractions into decimals

    Rachel works 2/3 of her shift: Approximately= 0.667

    Jose works 1/6: approx. = 0.1667

    Damon works 4/5= 0.80

    Stacy works 6/7: approx. = 0.8571

Now this makes it much easier to compare

And since 0.85714 (Stacy's shift) is the largest number, Stacy has completed the largest portion of her shift

Answer:

$30.53

Step-by-step explanation:

First, find the tax.  To do this, first convert the percentages to decimals.

6% = 0.06

20% = 0.2

Now, multiply the bill by the decimal to find the tax.

24 × 0.06 = 1.44

Add this to the bill to find the total.

24 + 1.44 = 25.44

Now that you have the total, multiply the total by the decimal to find the tip.

25.44 × 0.2 = 5.088 = 5.09

Add this tip to the total to find how much Mrs. Rodriguez should pay.

25.44 + 5.09 = 30.53

The total is $30.53.

Answer:

≅ $30.53

Step-by-step explanation:

I got this by first multiplying .06, the decimal form of 6%, by $24. That gave me the answer of $1.44. Once I had that I added it to the original price of $24.44. $25.44. Once I did that, I then multiplied .20, the decimal form of 20%, to the new total of $25.44, then added it to the total so that I could get a grand total of $30.528. Once I had this all I had to do was simply round to the hundredths place. So I got a grand total of $30.53.

Answer: 20 cm

If quadrilaterals WXYZ and BADC are congruent, then their corresponding sides are congruent.

Given that

WX≅DC,

XY≅BC,

you can state that

YZ≅AB,

WZ≅AD.

If AD = 4 cm and AB = 6 cm, then WZ = 4 cm and YZ = 6 cm. Opposite rectangle sides are congruent, then XY = 4 cm and WX = 6 cm.

The perimeter of WXYZ is

P = WX + XY + YZ + WZ = 6 + 4 + 6 + 4 = 20 cm.

m∠s = 93°

Step-by-step explanation:

We know that any quadrilateral's sum of angles adds up to 360°. In that case,

360 - (56 + 132 + 79) = m∠s

m∠s = 93°

Step-by-step explanation:

[tex]The- diagram- is- a- trapezoid (quadrilateral)\\Sum- of- angles-in a- quadrilateral = 360\\ 132\° + 56\° + 79\° + x\° = 360\° \\267\° + x\° = 360\° \\x = 360 \° - 267 \° \\x\° = 93\°[/tex]

Answer:

99.86%

Step-by-step explanation:

What we have here is a binomial distribution, let x be the baby number among 8 births.

Binomial (n = 8, p = 0.559)

We want to find, P (X ≥ 1)

P (X ≥ 1)    = 1 - P (X <1)

P (X ≥ 1)  = 1 - P (X = 0)

P (X = 0)   = 8C0 * (0.559) ^ 0 * (1 - 0.559) ^ (8-0)]

8C0 = 8! / (0! * (8-0)!) = 1

replacing we have:

P (X = 0)   = 1 * 1 * 0.0014

P (X = 0)  = 0.0014

P (X ≥ 1))  = 1 - 0.001 4

P (X ≥ 1) = 0.9986

Therefore the probability is 99.86%

Answer:

1370754

Step-by-step explanation:

From what I can see, you are probably studying combinations and permutations at the moment. Since this is a question about how many groups of five can be produced from a sample size of 46, the groups are random and not in order, which may rule for us to use the combination formula.

Once you compute this, this answer is basically saying that 1370754 groups of 5 can be created from a sample size of 46

Answer:

The probability of  successes   P( x < 4 ) = 0.36138

Step-by-step explanation:

Step(i):-

Given 'n'=9

The probability of success 'p' = 0.45

                                            q = 1-p = 1-0.45 = 0.55

Let 'X' be the random variable in Binomial distribution

[tex]P(X=r) = n_{C_{r} } p^{r} q^{n-r}[/tex]

[tex]n_{C_{r} } = \frac{n!}{(n-r)!r!}[/tex]

Step(ii):-

The probability of x successes in the n independent trials of the experiment

[tex]P(x<4) = P(x=0) +P(x=1)+P(x=2)+P(x=3)[/tex]

              = [tex]= 9_{C_{0} } (0.45)^{0} (0.55)^{9-0}+9_{C_{1} } (0.45)^{1} (0.55)^{9-1}+9_{C_{2} } (0.45)^{2} (0.55)^{9-2}+9_{C_{3} } (0.45)^{3} (0.55)^{9-3}[/tex]By using factorial notation

[tex]n_{C_{r} } = \frac{n!}{(n-r)!r!}[/tex]

[tex]9_{C_{0} } = 1 , 9_{C_{1} } = 9 , 9_{C_{2} } = 36, 9_{C_{3} } = 84[/tex]

P( x < 4 ) = (0.55)⁹ + 9(0.45) (0.55)⁸ + 36 (0.45)² (0.55)⁷ +84 (0.45)³ (0.55)⁶

P( x < 4 ) = 0.004605+0.03391 + 0.1109855+ 0.21188

P( x < 4 ) = 0.36138

Final answer:-

The probability of  successes   P( x < 4 ) = 0.36138

Answer:

sum of the angles of the triangle are 180°

Step-by-step explanation:

To find the sum of the interior angles, we use the formula( s-2*180), where s is the number of sides of the shape. If it is a pentagon, 5-2*180= 3*180= 540,

which shows that the sum of the interior angles of a pentagon is 540.

since, it is a triangle in the figure with 3 sides, 3-2*180=1*180=180.

The interior angles are unknown= a, b and c. we know that a+b+c=180 degrees and the exterior angles are mentioned. And we know that, opposite angles are equal. So, a is 40 degrees considering that 40 degrees is the opposite angle of a, b is 95 degrees whereas c is 45 degrees.

now, lets check if the angles indeed have a sum of 180 degrees,

40+95+45= 135+45 which gives 180 degrees.

Answer:

180°

Step-by-step explanation:

→ Angles in a triangles always add up to 180, we can prove this by calculating a, b and c so,

a = 40° (vertical angles are equal)

b = 95° (vertical angles are equal)

c = 45° (vertical angles are equal)

40 + 45 + 95 = 85 + 95 = 180°

Step-by-step explanation:

Given that y is inversely proportional to x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of proportion

(a)

To find k use the condition when y = 7 , x = 9, that is

7 = [tex]\frac{k}{9}[/tex] ( multiply both sides by 9 )

63 = k

y = [tex]\frac{63}{x}[/tex] ← equation of proportion

(b)

When x = 21, then

y = [tex]\frac{63}{21}[/tex] = 3

Answer:

AB: size 4 x 4

BA: size 2 x 2

Step-by-step explanation:

When we want to multiply two matrices, we need first to check if the number of columns of the first matrix is equal the number of rows of the second matrix. Then, the resulting matrix would have the number of rows equal the number of rows of the first matrix, and the number of columns equal the number of columns of the second matrix.

That is, if we have a matrix A with dimensions a x b and a matrix B with dimensions c x d, to calculate the product AB we must have b = c, and the resulting product would have dimensions a x d.

Finally, if A is 4 x 2 and B is 2 x 4, we would have:

AB = (4 x 2) (2 x 4)

2 = 2 -> product is possible.

Dimensions of the result: 4 x 4

BA = (2 x 4) (4 x 2)

4 = 4 -> product is possible.

Dimensions of the result: 2 x 2

The size of a matrix is its dimension,

The size of AB and BA are 4 x 4 and 2 x 2, respectively

The dimension of matrix A is given as 4 x 2, while the dimension of matrix B is  2 x 4

Product AB

The dimension of matrix AB is the row of matrix A by the column of matrix B.

Matrix A has 4 rows, while matrix B has 4 columns.

So, the dimension of matrix AB is 4 x 4

Product BA

The dimension of matrix BA is the row of matrix B by the column of matrix A.

Matrix B has 2 rows, while matrix A has 2 columns.

So, the dimension of matrix BA is 2 x 2

Hence, the size of AB and BA are 4 x 4 and 2 x 2, respectively

Answer:0.0081  or 0.81%

Step-by-step explanation:

The required probability is P(3,5,0.1)= C5 3 * p^3*q^2, where

C5 3=  5!/3/2=4*5/2=10

p is the probability that one randomly selected calculator is defective= 10%=0.1

q is the probability that one randomly selected calculator is non-defective.

q=1-p=1-0.1=0.9

So P(3,5,0.1)= 10*0.1^3*0.9^2=0.01*0.81=0.0081
