A. 5y3 + 5x2
B. (5y)3 - (5x)2
C. 5(y3 - x2)
D. (5y - 5x)^6

Answers

Given:

The statement is "Five times the difference of the cube of y and the square of x".

To find:

The algebraic expression for the given statement.

Solution:

We know that,

Cube = Power 3

Square = Power 2

Difference = Minus (-)

Times = Multiplication (×)

Now,

Cube of y = [tex]y^3[/tex]

Square of x = [tex]x^2[/tex]

Difference of the cube of y and the square of x = [tex]y^3-x^2[/tex]

Five times the difference of the cube of y and the square of x is:

Required expression = [tex]5(y^3-x^2)[/tex]

Therefore, the correct option is C. The required algebraic expression for the given statement is [tex]5(y^3-x^2)[/tex].

Answers

Answer:

3.27

Step-by-step explanation:

Let us assume that the values are the side of a right triangle where;

Hypotenuse = 6 (longest)

Angle of elevation = 33 degrees

Required

x = opposite side

Using the trig identity

Sin theta = opp/hyp

Sin 33 = x/6

x = 6sin33

x = 6(0.5446)

x = 3.27

Hence the value of x is 3.27

Note that the values of the sides are assumed.

Lucy Liu went shopping at Hollister with her friends together they spent a mean price of $40 on eight sweaters the first step and sweaters cost $50 $55 $30 $35 $39 $40 and $42 how much in dollars does the eighth sweater cost

Answers

Answer:he eighth sweater costs $29

Step-by-step explanation:

Let the price of the eighth sweater be re[presented as X

We know that

Mean Price =Total sum of cost of sweater bought/ Number of sweater'

Plugging in our known values we have that  

40=$50+ $55+ $30+ $35+ $39+ $40 + $42+X  /8

8 X 40 =291 +X

320=291 +X

X =320-291

X=29

Therefore, the eighth sweater costs $29

Can you slove this 6=2(y+2)

Answers

Answer:

y=1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6=2(y+2)

6=(2)(y)+(2)(2)(Distribute)

6=2y+4

Step 2: Flip the equation.

2y+4=6

Step 3: Subtract 4 from both sides.

2y+4−4=6−4

2y=2

Step 4: Divide both sides by 2.

2y/2  2/2

in the year 2001, a person bought a new car for $22000. for each consecutive year after that, the value of the car depreciated by 5%. how much would the car be worth in the year 2005, to the nearest hundred dollars

Answers

Answer:

To the nearest hundred dollars, the car will be worth $17,900 by 2005

Step-by-step explanation:

Firstly, we need to write the depreciation equation

We have this as:

V = I(1 - r)^t

V is the present value which is what we want to calculate

I is the initial value, the amount the cad was bought which is $22,000

r is the rate of change which is 5% = 5/100 = 0.05

t is the time difference which is 2005-2001 = 4

Substituting all these into the depreciation equation, we have it that

V = 22,000(1 -0.05)^4

V = $17,919.1375

To the nearest hundred dollars, that would be;

$17,900
