Answer:

2 cis (7/6 pi)

Step-by-step explanation:

r = sqrt( a^2 + b^2)

r = sqrt (-sqrt(3) )^2 + (-1)^2)

   = sqrt(3 +1)

    = sqrt(4)

    = 2

theta  = arctan (b/a)

theta = arctan (-1/-sqrt(3))

theta = 30

but this is in the third quardrant  -a and -b

so add 180

theta = 210 degrees

convert this to radians

210 * pi/180 = 210/180 * pi = 21/18 * pi = 7/6 * pi

r cis (theta)

2 cis (7/6 pi)

5 - 7 + 2 - 6 ÷ 2 + 24^3 * 7000 - 76 = 96,767,921

Exponentiation is performed first, followed by multiplication and division in their order of appearance.

= 5 - 7 + 2 - 6 ÷ 2 + 13,824 · 7000 -76

= 5 - 7 + 2 - 3 + 96,768,000 -76

Then addition and subtraction are peformed in the order of appearance. (The commutative and associative laws apply.)

= (5 -7 +2) +96,768,000 -3 -76

= 96,767,921

The area of the label for a cylindrical coffee can with a height of 14 cm and a radius of 5 cm is approximately 440 square centimeters.

The subject in this case is Mathematics, and the question pertains to the use of geometry to determine the area of a label on a cylindrical coffee can. Specifically, the question asks to calculate the area of the cylindrical surface (lateral surface), which will be used as the label area. To calculate this, one needs to use the formula for the lateral surface area of a cylinder, which is 2πrh, where r is the radius and h is the height of the cylinder.

Given a cylinder with a height of 14 centimeters and a radius of 5 centimeters, the area of the label can be calculated as follows:

Area = 2π(5 cm)(14 cm) = 2π×5 cm×14 cm = 2×3.1416×5 cm×14 cm ≈ 440 cm².

Answer:

t = 3

Step-by-step explanation:

The ball thrown vertically upward reaches its maximum height after 3 seconds, as calculated by setting the derivative of the position function, which represents the velocity, to zero.

The question is about determining how many seconds it will take for a ball thrown vertically upward to reach its maximum height. The ball's position as a function of time is given by 30t - 5t2 meters. To find when the ball reaches its maximum height, we need to find the time at which the velocity is zero. The velocity function is the derivative of the position function, which is 30 - 10t. Setting the velocity equal to zero gives us the time when the ball reaches its maximum height:

0 = 30 - 10t

t = 3 seconds

The ball will reach its maximum distance from the ground after 3 seconds.

To express in scientific notation, move the decimal so it is after the first non-zero digit, and count the number of steps as the power of 10. 42,670,000 becomes 4.267 * 10^7 and 0.0000008 becomes 8 * 10^-7.

To convert a value to scientific notation, you need to express it as a product of a number between 1 and 10 and a power of 10.

Answer:

Step-by-step explanation:

First put the point slope form equation into slope intercept form.

y−2=0.5(x+3)

y - 2 = .5x + 1.5

y - 2 + 2 = .5x + 1.5 + 2

y = .5x + 3.5

With it in the slope intercept form we can see that the y intercept is at (0,3.5)

Find a graph that has this as the y intercept. Next we can graph it like the picture I have attached. You graph the equation by inserting numbers for x.

Answer:

Step-by-step explanation:

The given equation is y - 2 = 0.5(x + 3)

Since the equation is of a straight line so we further rewrite the equation in the form of intercept form.

y - 2 = 0.5x + 1.5

y = 0.5x + 1.5 + 2

y = 0.5x + 3.5

Now plot the graph for the points suitable for the equation

x     0       2        -2         4        -4

y     3.5    4.5     2.5      5.5     1.5

Now the graph which matches the graph plotted will be the graph of the equation.

Answer:

Step-by-step explanation:

Given that total amount available is 90$

x represent the number of pens, and  y represent the number of pencils.

cost of each pen is 0.75 and cost of each pencil is 0.15

Then we have total cost = cost of pens + cost of pencils

= [tex]0.75x+0.15y[/tex]=90

Hence option B is right

For finding out the greatest number of each type of writing tool, we can make the other 0 and find out

Hence maximum x = [tex]\frac{90}{0.75} =120[/tex]

maximum y =[tex]\frac{90}{0.15} \\=600[/tex]

Part A

The equation that describes the number of club pens and pencils that the glee club can buy is 0.75x + 0.15y = 90

Part B

Greatest number of pens that the club can buy = 120

Greatest number of pencils that the club can buy = 600

Cost of each pen = $0.75

Number of pens = x

Cost of each pencil = $0.15

Number of pencils = y

Total cost on pens and pencils = $90

(Cost of each pen) x (Number of pens)  +  (Cost of each pencil)x(Number of pencils)  = Total cost

The equation that describes the number of club pens and pencils is:

0.75x  +  0.15y    =   90

The club buys the greatest number of pens when:

0.75x  = 90

x  =  90/0.75

x  =  120

Greatest number of pens that the club can buy = 120

The club buys the greatest number of pens when:

0.15x  = 90

x  =  90/0.15

x  =  600

Greatest number of pencils that the club can buy = 600

Comment on the problem

This result is "unexpected." Usually an interest amount will be positive. Please have your teacher work this problem for you and explain the result.

Vito Melvin started with $6,955.01 in his account, deposited $2,815.85, and withdrew $100. The expected balance was $9,670.86, but the actual balance was $9,669.26, meaning Vito earned $1.60 in interest.

This problem is about calculating interest earned on a bank account. Let's start by looking at Vito Melvin's actions with his bank account.

He began with a previous balance of $6,955.01. He then made a deposit of $2,815.85 and then withdrew $100. This means his new balance should be his previous balance plus his deposit minus his withdrawal. In calculation, (($6,955.01 + $2,815.85) - $100) = $9,670.86.

However, Vito's actual balance is $9,669.26. The difference between the expected balance ($9,670.86) and the actual balance ($9,669.26) is the interest he earned. So, subtract the actual balance from the expected balance to find the interest: $9,670.86 - $9,669.26 = $1.60.

Therefore, Vito Melvin earned $1.60 in interest.

Answer: y = one half x − 5

Step-by-step explanation:

We know that , the equation of line that passes through point (a,b) and has slope m is given by :-

[tex](y-b)=m(x-a)[/tex]

Given : Point = (a,b)=(2, -4)

Slope = [tex]\dfrac{1}{2}[/tex]

a1 = 65

Step-by-step explanation:

If the begining value is 65, then a1 has to be itL

a1 = 65

Then, if this amount increased every minute then 5 has to be added to this value each time:

an = 65 + 5

But this means that 5 is added to 65 every time with no increase, so the five must me multiplied by the n value:

an = 65 + 5[tex]_{n}[/tex]

a2 = 65 + 10 = 75

But this value should be 70 because it is the first point after 65 so it should be +5 not +10

To do this we can simply subtract one from the n value that is being multiplied by 5:

an = 65 + 5[tex]_{n - 1}[/tex]

=>1/2 = 17/y

=>y = 34

For this case we must find the value of y (Hypotenuse) and the value of x (leg adjacent to the 30 degree angle) of the triangle shown.

By definition:

[tex]Tangent (30) = \frac {17} {x}\\x = \frac {17} {Tangent (30)}\\x = \frac {17} {\frac {\sqrt {3}} {3}}\\x = \frac {17 * 3} {\sqrt {3}}\\x = \frac {51 \sqrt {3}} {3}\\x = 17 \sqrt {3}[/tex]

Now, we look for the value of y:

[tex]Sine (30) = \frac {17} {y}\\y = \frac {17} {sine (30)}\\y = \frac {17} {\frac {1} {2}}\\y = 34[/tex]

Answer:

1: The diver is 8 feet below sea level.

2: -20

3: -20 + 20 = 0

Step-by-step explanation:

1: This is determined by adding 4 to negative 12. -12 +4 = -8

2: You get this by subtracting 12 from negative 8. -8 - 12 = -20

3: This is done by adding 20 to negative 20. -20 + 20 = 0

The diver's depth in relation to sea level is determined by subtracting the ascent from the initial descent and subsequent descents are added or subtracted accordingly. To reach sea level from a negative depth, the diver needs to ascend by swimming.

The depth of the diver in terms of sea level is -8 feet. This was determined by subtracting the ascent of 4 feet from the initial descent of 12 feet below sea level, resulting in -8 feet.

The new depth of the diver in terms of sea level is -20 feet. This was determined by adding the additional descent of 12 feet to the previous depth of -8 feet below sea level, resulting in -20 feet.

The diver will reach sea level from the position found in part B by swimming up 20 feet. This will bring the depth of the diver to 0 feet below sea level, which is equivalent to sea level.

Answer:

2b³ +2a -2c . . . . degree 3 polynomial

Step-by-step explanation:

The monomials are ...

... 4a . . . . degree 1 in a

... -5b·b² = -5b³ . . . . degree 3 in b

... -3c . . . . degree 1 in c

... 7b³ . . . . degee 3 in b (like term with -5b³)

... +c . . . . degree 1 in c (like term with -3c)

... -2a . . . . degree 1 in a (like term with 4a)

So, we have 3 pairs of like terms. The like terms can be combined by summing their coefficients.

The degree of the polynomial is that of the highest-degree term. (Here, the b³ term makes it a polynomial of degree 3.)

... 4a -2a = (4-2)a = 2a . . . . combining the "a" terms

... -5b³ +7b³ = (-5+7)b³ = 2b³ . . . . combining the b³ terms

... -3c +c = (-3 +1)c = -2c . . . . combining the "c" terms

In standard form, we write the highest-degree term first. Follwing terms are in order by decreasing degree. It is convenient, but perhaps not required, to then write the terms of the same degree in alphabetical order.

... = 2b³ +2a -2c . . . . a 3rd degree polynomial

(a) To make use of the forms of the equation for a line this problem requires, we must first calculate the slope (m) of the line between the two given points. That is computed by ...

... m = (change in y)/(change in x)

... m = (8 -3)/(2 -0) = 5/2

The second given point tells us the y-intercept (b) is 3, so the equation for the line is ...

... y = mx + b

... y = 5/2x + 3

(b) As in part (a), we must calculate the slope of the line. That is ...

... m = (change in y)/(change in x)

... m = (4 -3)/(1 -3) = 1/(-2) = -1/2

Using the first point (h, k) in the point-slope form of the equation of a line, we have ...

... y -k = m(x -h)

... y -4 = -1/2(x -1) . . . . . point-slope equation

Simplifying this, we get

... y = -1/2x +1/2 +4

... y = -1/2x +9/2 . . . . . slope-intercept equation

(c) The slopes of the two equations are different, so they must intersect at exactly one point. The equations are consistent.

(d) We can substitute the "y" from one equation into the other to give ...

... 5/2x +3 = -1/2x +9/2

... 3x = 3/2 . . . . . . . add 1/2x -6/2

... x = 1/2 . . . . . . . . divide by 3

Using the first equation to find y:

... y = (5/2)·(1/2) +3 = 5/4 +12/4

... y = 17/4

The point of intersection is (x, y) = (1/2, 17/4).
