Simplify (-64)2/3.

Answers

Answer:

As a proper fraction. (numerator smaller than denominator): 2/3 = 2/3

As a decimal number: 2/3 ≈ 0.67.

As a percentage: 2/3 ≈ 66.67%

That's all I can provide

The value of the expression (-64)^(2/3) can be simplified as 16.

Given an expression (-64)^(2/3).

We have to find the value of the expression.

We have the rules of exponents that,

aᵇⁿ = (aᵇ)ⁿ

Using this rule, the expression can be written as,

(-64)^(2/3) = (-64²)^(1/3)

                 = (4096)^(1/3)

Now,

(a)^(1/3) is equal to ∛a.

(-64)^(2/3) = ∛4096

                 = 16

Hence the correct option is B.

A ball is thrown in the air from the top of a building. Its height, in meters above ground, as a function of time, in seconds, is given by h(t)=−4.9t2+21t+6. How long does it take to reach maximum height?

Answers

Answer:

we have to find the derivate of that function which is: -4.9*2t +21 and to find the maximum height this derivate should be equal to 0

-9.8t+21=0 so

t=21/9.8=2.14

An office supply company ordered 24 cartons of specialty paper. The regular price for a carton of specialty paper is $6.88. They received a discount of $1.75 off each carton. About how much money will the office supply company need to pay for the paper? Which of the expressions gives a reasonable estimate of the answer? A. $5 × 25 B. $6 × 25 C. $7 × 20 D. $9 × 30

Answers

Answer: A. $5 × 25

Step-by-step explanation:

Given the following :

Number of cartons of specialty paper ordered = 24 cartons

Regular price for a carton = $6.88

Discount given off each carton = $1.75

Hence,

Discounted price per carton = $(6.88 - 1.75) = $5.13

Actual amount to be paid for the order :

Discounted price * number of cartons to be ordered

$5.13 * 24

Hence, a reasonable estimate will be :

$5.13 = $5( nearest whole number)

24 can be rounded to 25 (this covers for the $0.13 on the discounted cost per carton)

Reasonable estimate :

$5 × 25

Answer:

The answer is  A. $5 × 25

Step-by-step explanation:

Given that the total number of cartons is 24

the price per carton originally is $6.88

the discount is $1.75

hence the company will have to pay 6.88-1.75= $5.13

hence the price per carton upon removal of the discount is  $5.13

for all 24 cartons, the company will have to pay 24*5.13  

A reasonable estimate from the given option is  

A. $5 × 25

Note: The given equation cannot be proven. Instead I will prove:

Use the Reciprocal Identity:  cot A = (cos A)/(sin A)

Use the following Double Angle Identities:

sin (2A) = 2 sin A · cos A

LHS = RHS [tex]\checkmark[/tex]

Answer:

see proof below

Step-by-step explanation:

cot(2a) = (cot^2a - 1)/2cota

Remember that cotangent is the inverse of tan...

cot = 1/tan => cot(2a) = 1/tan2a

Here I used the formula for tan2a, or in other words tan2a = 2tana/1 - tan^2a

Therefore the inverse of tan2a, 1/tan2a, should be the inverse of 2tanA/1 - tan^2a, or 1 - tan^2a/2tana => 1/tan2a = 1 - tan^2a/2tana = cot(2a)

The reverse is true as well, tan is the inverse of cotangent...tanA = 1/cotA

cot(2a) = 1 - tan^2a/2tana = 1 - (1/cot^2a)/2(1/cota)

= cot^2a - 1/cot^2a * cota/2

= cot^2a - 1/2cota

The formula c = 5p + 210 relates c, the total cost in dollars of hosting a birthday party at a skating rink, to p, the number of people attending. If Allie's parents are willing to spend $350 for a party, how many people can attend?

Answers

Answer:

28 people

Step-by-step explanation:

Plug in 350 as c into the equation, since c is the total cost:

c = 5p + 210

350 = 5p + 210

Solve for p:

140 = 5p

28 = p

So, 28 people can attend

Step-by-step explanation:

B is the midpoint of ac. Ab = x+9 and bc = 3x-7 find x and ac

Answers

To solve this problem, we need to know 2 relationships:

1. AC = AB + BC

The distance of AC is the sum of AB and BC.

[tex]AC = AB + BC[/tex]

We know this since the distance of going from A to C (AC) is the same as going from A to B (AB), then B to C (BC).

2. AB = BC

The distance of AB is the same as AC.

[tex]AB = BC[/tex]

We know this since B is in the middle of AC, so the distance from B to A (BA) is the same as the distance from B to C (BC).

You can see the attached image (at the bottom) for a visualization of this.

Putting them together

Since we know the values of AB and BC...

[tex]AB = x+9\\BC = 3x-7[/tex]

...we can put these values into our 2nd equation and solve for x:

[tex]AB = BC\\x + 9 = 3x -7[/tex]

Add 7 to both sides:

[tex]x + 16 = 3x[/tex]

Subtract x from both sides:

[tex]16 = 2x[/tex]

Divide both sides by 2:

[tex]8 = x\\x = 8[/tex]

Knowing x, we can find the distance of AC using our first equation.

[tex]AC = AB + BC[/tex]

Let's put in the values of AB and BC:

[tex]AC = (x+9) + (3x-7)[/tex]

Before we put in x = 8, we can simplify this:

[tex]AC = (x+9) + (3x-7)\\AC = x + 9 + 3x -7\\AC = x + 3x + 9 -7\\AC = 4x + 9 - 7\\AC = 4x+2[/tex]

We group x and 3x and add those together. Then we subtract 7 from 9.

With this equation, we can put in x = 8:

[tex]AC = 4x +2\\AC = 4*8 + 2[/tex]

Since 4 * 8 = 32:

[tex]AC = 4 * 8 + 2\\AC = 32 + 2\\AC = 34[/tex]

Finally, we have found both x and AC.

Answer

x = 8

AC = 34

Step-by-step explanation:

Each term has 'x' so we know that we can factor out the 'x'. Then we are left with

x(33+88+110)

All three of the numbers inside the parenthesis are divisible by 11. So we will get
