Answer:

Octopus Location: 0

Step-by-step explanation:

If the octopus was swimming 3 ft below the surface, it's considered -3.

The octopus then swam up 3 feet, so we add 3 to the -3 from the previous statement.

-3 + 3 = 0

Answer:

  sin(θ) = -12/13

Step-by-step explanation:

The distance from the origin to the given point is ...

  r = √(5² +(-12)²) = √169 = 13

For point (x, y) ⇔ (r; θ), recognize that (x, y) = (r·cos(θ), r·sin(θ)). This translates to ...

  sin(θ) = y/r

  sin(θ) = -12/13

Answer:

A

Step-by-step explanation:

[tex] \frac{4x - 3}{7} [/tex]

Replace y with x.

[tex]x = \frac{4y - 3}{7} [/tex]

Solve for y.

[tex]7x = 4y - 3[/tex]

[tex]{7x + 3}{} =4 y[/tex]

[tex] \frac{7x + 3}{4} = y[/tex]

Answer:

16pieces

Step-by-step explanation:

We can find the number of pieces is the amount steve make is $256

If steve makes $256, then f(x) = 256

Substitute into the formula and find x

256 = 16x

Swap

16x = 256

Divide both sides by 16

16x/16 = 256/16

x = 16

Hence the number of jewelry sold is 16pieces

Answer: 2

Step-by-step explanation:

2+2+1+3=8/4=2

Answer:

2

Step-by-step explanation:

Use the dot plot to make a list of the numbers it represents, sorted from smallest to largest.

0, 0, 0, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 4, 4, 4, 5, 5, 6, 9

There are 23 numbers in this list. The median is the one in the middle, so there will be 11 numbers to the left of it and 11 to the right.

The median is 2

Answer:

b) 9.99 + 1.29n ≤ 50

Step-by-step explanation:

  I think,  this question is incomplete., may be there is typo. To complete the question, it's suppose to be like this  

a)9.99 + 1.29n ≥ 50

b)9.99 + 1.29n ≤ 50

c)9.99 − 1.29n  ≤ 50

d)9.99 − 1.29 n ≥ 50

well,  we have to figure out  the information given  

price of the album: $9.99

each song cost : $1.29

gift card: $50

number of songs : n

The answer  is b) 9.99 + 1.29n  ≤ 50 , because the sum of the price of the album ($9.99) and the songs ($1.29 n) must be less or equal to the value of the gift card ($50). Fore sure it 's correct.....

Step-by-step explanation:

3-3/21-8

0/21-8

0/13

0

Answer:

(8, 3) (21, 3)

slope = change in y divided by change in x

slope = (3 - 3) / (21 -8)

slope = 0 / 13

slope = 0

Step-by-step explanation:

Answer:

x = y = 24 units

Step-by-step explanation:

By using the property,

"Radius of a circle perpendicular to a chord bisects the chord in two equal parts"

Since, radius AE is perpendicular to the chord AB,

AD = BD

x = y

AO = OC = 25 [Radii of a circle are equal in measure]

By applying Pythagoras theorem in ΔADO,

AO² = AD² + OD²

(25)² = x² + 7²

625 = x² + 49

x² = 625 - 49

x = 24 units

Therefore, x = y = 24 units

Answer:

answer is B

Step-by-step explanation:

The solution to the equation is 4 or x = 4 because the x-value of 4 produces the same y-value in both f(x) = (x - 2)³ – 6 and g(x) = ∛(x + 4) option (D) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have an equation in terms of x:

(x - 2)³ – 6 = ∛(x + 4)

To find the value of x we can solve it by trial and error method:

Plug x = 4 in the equation:

(4 - 2)³ – 6 = ∛(4 + 4)

(2)³ – 6 = ∛(8)

8 - 6 = 2

2 = 2 (true)

The solution to the equation is x = 4

Thus, the solution to the equation is 4 or x = 4 because the x-value of 4 produces the same y-value in both f(x) = (x - 2)³ – 6 and g(x) = ∛(x + 4) option (D) is correct.

Answer:

The data is a random sample from the population of interest and The sample size is less than 10% of the population size. ( b )

Step-by-step explanation:

roasted beef protein = 20 grams  ( mean value )

sample size of soybean compound = 5

mean value of their protein = ( 15 + 22 + 17 + 18 + 23)  / 5 = 19

The conditions that have been met are :

The data is a random sample from the population of interest. and

we can say the sample size is less than 10% of population size because we do  know the population size is a large supply

Answer:

V= 8

x=4.5

BCF =48 CFE=132

V=352.8 =8.4x8.4x5

For the volume one i cant read the number but if the bottom number is 8 then V=803.84

if its 6 then v = 452.16

Step-by-step explanation:

v= 2x2x2 v = 8

x is 11x-9=7x+9 | 4x=18 | x=4.5

15x=180 x=12 | CFE = 11x12=132 | BCF = 4x12=48

Answer:

[tex]x^3+8x^2+2x+1[/tex]

Step-by-step explanation:

Combine like terms (terms with the same exponent).

[tex]x^3+(3x^2+5x^2)+(x+x)+1=x^3+8x^2+2x+1[/tex]

"Standard form" means to list terms so the exponents go from high to low (descending order).

Answer:

Step-by-step explanation:

Step-by-step explanation:

Let x and y denote the cost of one hot dog and the cost of one hamburger.

ATQ,

Five hot dog(s) and four hamburger(s) cost $16.75 and four hot dog(s) and five hamburger(s) cost $17.00

So,

5x+4y = 16.75 ....(1)

4x + 5y = 17 ....(2)

Multiply equation (1) by 4 and equation (2) by 5.

20x+16y = 67 ....(3)

20x+25y= 85 ....(4)

Subtract equation (3) and (4).

20x+16y-(20x+25y) = 67-85

16y-25y = -18

-9y = -18

y = 2

Put the value of y in equation (2).

4x + 10 = 17

4x = 7

x = 1.75

So, the cost of one hot dog is $1.75 and that of cost of one hamburger is $2.

Answer:

The surface area of the composite figure is 1108 square inches.

Step-by-step explanation:

The surface area of the composite figure ([tex]A_{T}[/tex]) is equal to the sum of external faces of the rectangular and triangular prisms, all measured in square inches:

[tex]A_{T} = 20\,in \times 12\,in + 2\times 5\,in \times 12\,in + 2\times 20\,in \times 5\,in + 2\times 20\,in \times 11\,in + 2\times \frac{1}{2}\times 12\,in \times 9\,in[/tex]

[tex]A_{T} = 1108\,in^{2}[/tex]

The surface area of the composite figure is 1108 square inches.

Hello, I Am BrotherEye

Answer:

A. Yes a triangle can be constucted

Step-by-step explanation:

All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.
