Answer:

The correct option is letter D.

Step-by-step explanation:

We have the following expression:

sqrt(y^3) + sqrt(9y^3) - 3y*sqrt(y)

We now that sqrt(a*b) = sqrt(a)sqrt(b)

Applying this rule, we have:

sqrt(y^3) + sqrt(9y^3) - 3y*sqrt(y)

sqrt(y^3) + 3sqrt(y^3) - 3y*sqrt(y)

Also we know that a*sqrt(b) = sqrt(b*a^2)

Applying this we have:

sqrt(y^3) + 3sqrt(y^3) - 3y*sqrt(y) = sqrt(y^3) + 3sqrt(y^3) - 3sqrt(y^3)

Then the result is:

sqrt(y^3) + 3sqrt(y^3) - 3sqrt(y^3) = sqrt(y^3) = y*sqrt(y)

The correct option is letter D.

Step-by-step explanation:

The area (A) of a rhombus is calculated as

A = [tex]\frac{1}{2}[/tex] × d₁ × d₂ ← diagonals

The diagonals of a rhombus are perpendicular bisectors of each other, thus

d₁ = 7 + 7 = 14 and d₂ = 9 + 9 = 18, hence

A = 0.5 × 14 × 18 = 126 cm²

The area of the rhombus is equal to 126 cm². The correct option is B.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rhombus in a two-dimensional plane is called the area of the rhombus.

The area (A) of a rhombus is calculated as

A =  × d₁ × d₂ ← diagonals

The diagonals of a rhombus are perpendicular bisectors of each other,

d₁ = 7 + 7 = 14

d₂ = 9 + 9 = 18, hence

The area of the rhombus will be calculated as,

A =  0.5 × d₁ × d₂

A = 0.5 × 14 × 18

A = 126 cm²

Therefore, the area of the rhombus is equal to 126 cm². The correct option is B.

Answer:

1, 2, 3, 5

Step-by-step explanation:

The dress is originally 160$, but we take 30% off which is that same as .3 .

To find 30% or .3 of 160 we multiply 160 by .3 which gets us 48.

48 is 30% of 160 so to find the new price of the dress we need to subtract

160 - 48 = 112. The new price of the dress is 112$.

Since Claire's aunt works at the store Claire will get an additional 10% off from the "new" price which is 112$.  10% is also .1, so we will multiply 112 by .1 which equals 11.20.

As 10% of 112 is 11.20 so we will subtract 11 dollars and 20 cents from the price. 112 - 11.20 = 100.80$.

For sales tax we will do the same thing, multiply 100.80 by .075 which equals 7.56. This time since we are ADDING sales tax, we will add 100.80 and 7.56 rather than subtract. 100.80 + 7.56 = 108.36.

Claire will be paying 108.36$ for the prom dress.

Answer:

The surface area of the rectangular prism is 700 units² ⇒ answer A

Step-by-step explanation:

* Lets revise how to find the surface are of the rectangular prism

- The rectangular prism has 6 rectangular faces

- Each two opposite faces are equal

- It has 4 side faces and 2 bases

* We can find the surface area of it by adding the area of

 the 6 faces

- In the problem

# The dimensions of the bases are 12 units and 14 units

# The dimensions of the side faces are 12 units and 7 units,

   14 units and 7 units

* Now lets find the area of each 2 equal faces

- In the bases

∵ Area of the rectangle = length × width

∴ The area of one base =  12 × 14 = 168 units²

∴ The area of the two bases = 2 × 168 = 336 units² ⇒ (1)

- In the two opposite faces with dimensions 12 units and 7 units

∵ The area of one face = 12 × 7 = 84 units²

∴ The area of the two faces = 2 × 84 = 168 unit² ⇒ (2)

- In the two opposite faces with dimensions 14 units and 7 units

∵ The area of one face = 14 × 7 = 98 units²

∴ The area of the two faces = 2 × 98 = 196 unit² ⇒ (3)

* To find the surface area of the prism add (1) , (2) , (3)

∴ The surface area of the prism = 336 + 168 + 196 = 700 units²

* The surface area of the rectangular prism is 700 units²

Answer: True

Step-by-step explanation:

By definition for a function of the form:

[tex]ax ^ n + ... + bx + c[/tex]

It is true that if [tex]a <0[/tex] and n is odd then:

[tex]\lim_{n \to -\infty}ax^n + ...+bx+c = \infty[/tex]

In this case

[tex]f(x)=-2x^3-2x^2+7x-25[/tex]

Therefore

[tex]a=-2<0[/tex] and [tex]n =3[/tex] → odd number

Then

[tex]\lim_{n \to -\infty}-2x^3-2x^2+7x-25= \infty[/tex]

Answer: c. The class median is lower than the exam median.

Step-by-step explanation:

the median is at a lower point on the number line, its to the left of the exam, so that means its lower

Answer:

1. We already have the measure of the hypotenuse and one out of two acute angle, therefore:

sin53° = x/45 => x = sin53° · 45 ≈35.94

2. We already have one out of two legs of the triangle and one acute angle so we know that:

tan27° = 48/x => x = 48/tan27° ≈ 94.21

The value of x in the first right angle triangle is 27.08.

The value of x in the second right angle triangle is 24.46.

In order to determine the value of x in the first triangle, cos would be used.

Cos 53 = opposite / hypotenuse

Cos 53 = x / 45

0.7071 = x /45

x = 45 x 0.6018

x = 27.08

In order to determine the value of x in the second triangle, tan would be used.

Tan 27 = opposite / adjacent

Tan 27 = x / 48

x = 0.5095 x 48  

x = 24.46

[tex]f\left(x\right)=(x+4)^{\frac{1}{3}}+4[/tex]

Step-by-step explanation:

Given function is [tex]f\left(x\right)=x^{\frac{1}{3}}[/tex]

Now it says that function is shifted 4 units to the left and 4 units up.

We need to find about which of the given choice is correct for the given transformation.

When f(x) is shifted "h" units left then we write f(x+h)

So [tex]f\left(x\right)=x^{\frac{1}{3}}[/tex] will change to

[tex]f\left(x\right)=(x+4)^{\frac{1}{3}}[/tex]

When f(x) is shifted "h" units up then we write f(x)+h

So [tex]f\left(x\right)=(x+4)^{\frac{1}{3}}[/tex] will change to

[tex]f\left(x\right)=(x+4)^{\frac{1}{3}}+4[/tex]

Answer:

C

Step-by-step explanation:

For a function f(x) = [tex]x^{\frac{1}{3}}[/tex], we have:

Keeping these translation rules in mind, we can clearly say that 4 units shifted left and 4 units up has the equation  [tex]f(x)=(x+4)^{\frac{1}{3}}+4[/tex]

correct answer is C

In the village of 3500 people, 63 individuals are both left-handed and have blonde hair.

To find out how many people in the village are both left-handed and have blonde hair, we first need to calculate the number of left-handed people, and then find 15% of that number to determine those who are also blonde.

Therefore, 63 people in the village are both left-handed and blonde-haired.

Answer:

2 hours,  142 miles

Step-by-step explanation:

Write a distance formula for both cars and then equate these formulas:

Car A:  y = 55x + 32  =  y = 42x + 58:  Car B

Then 55x + 32  =  y = 42x + 58  →  13x = 26, and so x = 2

That distance will be 55(2) + 32, or 142 miles.

The cars will reach the same point after 2 hours (first possible answer)

An equation is formed when two equal expressions. The correct option is A, 2hours, and 142 miles.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the equation for the distance covered by car A in x hours is y = 55x + 32, similarly, the equation for the distance covered by Car B in x hours is y=42x+58.

Now, to know at what time and at what distance the two cars will meet we need to solve the two equations. Since the car will cover the same distance we can write,

y = y

55x + 32 = 42x + 58

55x - 42x = 58 - 32

13x = 26

x = 2

Substitute the value of x in any one of the equations,

y = 55x + 32

y = 55(2) + 32

y = 110 + 32

y = 142

Thus, the car will meet after 2 hours, and the distance will be 142 miles.

Hence, the correct option is A, 2hours, and 142 miles.

Step-by-step explanation:

The probability of tossing 6 tails in a row with a fair coin is 1/64, as each toss's outcome is independent and the probability of tail on a single toss is 1/2.

To compute the probability of tossing 6 tails in a row with a fair coin, you recognize that for each individual toss, the probability of getting a tail is ½. Since each toss is independent, you simply multiply the probabilities of each event occurring consecutively. Therefore, the probability of tossing 6 tails in a row is:

(½) × (½) × (½) × (½) × (½) × (½) = ½6

½6 = 1/64

So, the probability of tossing 6 tails in a row is 1/64.

Answer:

C. (-1, 0)

Step-by-step explanation:

(You don't need a picture to figure this out...it's simple algebraic manipulation.)

We could start off by rewriting the equation for the parabola with the negative on the other side, which tells us then that the parabola opens downward:

[tex]-(x+1)^2=8(y-2)[/tex]

Dividing both sides by -1 doesn't change anything.  Because this parabola opens downward, the focus is p units below the vertex at the same x-coordinate.  The vertex can be found from the equation to be (-1, 2).  The standard form of a parabola of this type is

[tex]-(x-h)^2=4p(y-k)[/tex]

where is the number of units between the vertex and the focus.  Our equation to find p is:

4p = 8 so p = 2.

That means that the focus is 2 units below the vertex at the x coordinate of -1.  Moving 2 units down from the y coordinate of 2 leaves us at a y coordinate of 0.  Therefore, the coordinates of the focus have to be (-1, 0)
