the cube root of the product of sixty-four, x cubed, and y to the eighth power​

Answer:

A. 30cm

Step-by-step explanation:

You would need to use the Pythagorean Theorem to find the answer. The theorem is a^2+b^2=c^2.

A and B represent the legs and C represents the hypotenuse.

Now substitute the values: 18^2+24^2=c^2

Calculate the exponents: 324+576=c^2

Now add: 900=c^2

Find the square root of 900: 30

So, the length of the hypotenuse is 30cm.

Let X= Cost of pears Let Y= Cost of peaches.

Solve question using a system of equations.

5X + 6Y = 11.20

3X = 2Y

Simplify the second equation to solve for Y.

3X = 2Y

Y = 1.5X

Substitute Y into the first equation.

5X + 6(1.5X) = 11.20

Simplify.

14X = 11.20

Solve for X:

X = 0.8

Substitute the value into one of the equations.

3X = 2Y

3(0.8) = 2Y

2.4 = 2Y

Y = 1.2

Each pear is $0.80 and each peach is $1.20.

Answer:

D

Step-by-step explanation:

Any statement claiming <1 and <2 = 90 is incorrect.

So the answer must be one of B or D

D is a bit incomplete, but it is your best answer. The next step would be to subtract <2 from both sides.

the answer is D , it makes the most sense for this problem

Answer:

B

Step-by-step explanation:

Using the rule of logarithms

• [tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]

Given

[tex]log_{x}[/tex] ([tex]\frac{1}{8}[/tex] ) = - [tex]\frac{3}{2}[/tex], then

[tex]\frac{1}{8}[/tex] = [tex]x^{-\frac{3}{2} }[/tex]

Square both sides

[tex]\frac{1}{64}[/tex] = [tex]x^{-3}[/tex]

[tex]4^{-3}[/tex] = [tex]x^{-3}[/tex] ⇒ x = 4 → B

Answer: Third option.

Step-by-step explanation:

We know that the sine function is:

[tex]f(x)=Asin(bx)[/tex]

Where "A" is the amplitude of the function( This is half the vertical distance between minimum value and maximum value of the function) and [tex]\frac{2\pi }{b}[/tex] is the period.

Observe in the graph that the amplitude is:

[tex]A=1[/tex]

And the period is 1, then "b" is:

[tex]1=\frac{2\pi }{b}\\\\b=\frac{2\pi }{1}\\\\b=2\pi[/tex]

Then the function shown in the graph is:

[tex]f(x)=sin(2\pi x)[/tex]

By definition in the transformation of the function:

When [tex]kf(x)[/tex] and [tex]k>1[/tex] then the function is stretched vertically by a factor of "k".

In this case we know that the function shown in the graph is vertically stretched by a factor of 2 to produce a new graph. Then:

[tex]k=2[/tex]

Therefore,the function that represents the new graph is:

[tex]f(x)=2sin(2\pi x)[/tex]

For this problem you need to know distance formula, which is

d=√(x2-x1)²+(y2-y1)². You'll want to plug in (0,3) and (-2, 9) and go on to plug in all of them at some point. You'll get 6.32 as the distance between (0,3) and (-2, 9), 3.61 as the distance between (-2, 9) and (-4, 6), and 5 as the distance between (-4, 6) and (0, 3). You add them up and get your answer.

Answer:

C 13,7,1

Step-by-step explanation:

The given expression is [tex]y=-3x+7[/tex].

To find the corresponding y-values, we need to plug in the x-values.

When x=-2, [tex]y=-3(-2)+7[/tex],  [tex]\implies y=6+7=13[/tex]

When x=0, [tex]y=-3(0)+7[/tex],  [tex]\implies y=0+7=7[/tex]

When x=2, [tex]y=-3(2)+7[/tex],  [tex]\implies y=-6+7=1[/tex]

Therefore the numbers that completes the table are: 13,7,1

The correct answer is C

Company C and Company D both manufacture batteries having the greatest variation in lifespan, which is an 8 month variation. This was determined by calculating the range of each data set.

The variation in lifespan for each company's laptop battery can be determined by looking at the range of the data, which is found by subtracting the smallest value (minimum) from the largest value (maximum). So we have:

As we can see, Company C and Company D both have the greatest variation in lifespan of their laptop batteries, with a range of 8 months.

Answer:

[tex]\frac{1}{3}(base area)(height)[/tex]

Step-by-step explanation:

Hi!

For the Pyramid´s volume equation is referred to one third of the area base multiply for the height of the pyramid. Take into account that the base area just going to change for the kind of base you will have into the pyramid, for example if the base is rectangular you have to use the equation a for it while for a triangular base you have to use equation b

Equation a

base X height

Equation b    

base X (height)/2

Answer:

$27508.

Step-by-step explanation:

We have been given that the value of certain truck after x years is represented by equation [tex]v(x)=32500(0.92)^x[/tex]. We are asked to find the value of truck after 2 years.

To find truck's value after 2 years, we need to substitute [tex]x=2[/tex] in our given equation.

[tex]v(2)=32500(0.92)^2[/tex]

[tex]v(2)=32500*0.8464[/tex]

[tex]v(2)=27508[/tex]

Therefore, the truck is worth $27508 after 2 years.

okay so you should know that the formula for a triangle is:

A=1/2×b×h

where b is breadth and h is height

A is area

so they already gave the area which is 16.2 and they already gave a side ( doesn't matter if it's b or h in this question)

so we put these into the equation of the area of a triangle

A=1/2×b×h

16.2=1/2 × 6 × h

then you will solve algebraically to get 5.4cm which is you answer

to check if correct you can always put in all numbers in equation and you should get 16.2cm

In this case it's correct ✌

Answer:

AC = 5.4 cm

Step-by-step explanation:

The area (A) of a triangle is calculated using the formula

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here AC is the base (b) and AB the height (h), thus

[tex]\frac{1}{2}[/tex] × AC × 6 = 16.2

3AC = 16.2 ( divide both sides by 3 )

AC = 5.4 cm

ANSWER: THE SOLUTION OF GIVEN INEQUALITIES IS ALL REAL NUMBER EXCEPT [1.167,3.5].

Answer:

Sample Response: When solving the first inequality, you get x > 3.5. When solving the second inequality, you get x < 3.5. The solution of an "or” compound in equality is everything in both solution sets, so the solution set is all of the numbers less than 3.5 and greater than 3.5. Since neither of the inequalities includes 3.5, the compound inequality has a solution of all real numbers except 3.5.

Answer:

key features are the slopes of both linear functions, if they are not equal then the two linear  functions will be intercepted

Step-by-step explanation:

Any linear function can be represented by the following linear equation:

y=mx+b

where m is the slope of function

and y in the intercept

Given:

The SneakerRama Company makes and sells sneakers.

They have one linear function that represents the cost of producing sneakers

Let it be represented by y₁=m₁x+b₁

and another linear function that models how much income they get from those sneakers

Let it be represented by y₂=m₂x+b₂

Now if m₁≠m₂

then the two functions will intercept at some point on the graph at some value of x. At that point the cost of producing sneakers will be equal to income they get from those sneakers.

y₂-y₁=0

This point is called the break-even point and the profit is zero at this point !

Answer:

61 second I would say but what is the weight of the rock?

Answer:

Option B. 7.8 seconds

Step-by-step explanation:

Shyanne drops a rock from a hill at initial height of 975 feet above the ground level.

We have to calculate the time taken by rock to hit the ground.

As we know the formula of motion under gravity is

h = ut + [tex]\frac{1}{2}gt^{2}[/tex]

Here h = initial height = 975 feet

u = initial velocity = 0

t = time taken by the rock to hit the ground

g = 32.174 [tex]\frac{\text{Feet}}{\text{Second}^{2}}[/tex]

Now we plug in these values in the formula

975 = 0 + [tex]\frac{1}{2}(32.174)(t)^{2}[/tex]

975 = 16.087t²

t² = [tex]\frac{975}{16.087}[/tex]

t = [tex]\sqrt{60.60}[/tex]

t = 7.78 ≈ 7.8 seconds

Option B. 7.8 seconds is the answer.

Answer:

Liberty Hill

Step-by-step explanation:

It rises the most over the same horizontal distance

Answer:

Liberty Hill. For every 4 feet at a horizontal distance, it rises 3 ft at the vertical rise of the street.

Step-by-step explanation:

Looking at the data, we can trace a parallel to the Cartesian Plane. As the Horizontal Distance would be the x-axis and the Vertical Axis, y-axis. So to determine the steepest hill we need to check the slope.

Like this:

Reference point (0,0)

Dixie Hill

[tex]m=\frac{40-0}{80-0}=\frac{1}{2}[/tex]

Bell Hill

[tex]m=\frac{20-0}{80-0} =\frac{20}{80}=\frac{1}{8}[/tex]

Liberty Hill

[tex]m=\frac{60-0}{80-0} =\frac{60}{80}=\frac{3}{4}[/tex]

The base Liberty Hill makes the largest angle, therefore the steepest hill.

For every 4 feet at a horizontal distance, it rises 3 ft at the vertical rise of the street.
