2^3 = 83^2 = 93^3 = 274^3 = 645^2 = 258^2 = 64

==============================================

Explanation:

The notation 5^2 is the same as writing [tex]5^2[/tex]

The second number is the exponent and it tells us how many copies of the base to multiply together. In the example 5^2, we have two copies of 5 multiplied to get 5^2 = 5*5 = 25

As another example, 4^3 = 4*4*4 = 64. We have three copies of 4 multiplied due to the exponent 3. You can use a calculator for this, but I recommend doing this by hand to get practice.

Note how 4^3 = 64 and 8^2 = 64. So 64 is used twice (which is why we have two tiles labeled "64").

The tiles labeled 9, 12, 10, and 16 are never used since they don't have any matching exponential expression.

Apositive integer n is called special if n is divisible by 4. n +1 is divisible by 5, and n + 2 is divisible by 6. How many special integers smaller than 1000 are there,​

Answers

Answer: 17

Hello,

Step-by-step explanation:

n is divisible by 4.

n +1 is divisible by 5

n + 2 is divisible by 6

n <1000

[tex]\left\{\begin{array}{ccc}n&=&4*k_1\\n+1&=&5*k_2\\n+2&=&6*k_3\\\end{array}\right.\\\\4*k_1+1=5k_2\Longrightarrow\ k_2=\dfrac{4k_1+1}{5} \Longrightarrow\ k_1=1+5*t\ , k_2=1+4*t\\\\4*k_1+2=6k_3\Longrightarrow\ k_3=\dfrac{4(1+5t)+2}{6} \Longrightarrow\ k_3=1+\dfrac{10*t}{3} \\\\\Longrightarrow\ t=3z\\k_3=1+10z\\n+2=6(1+10z)\\n=4+60z\\\\1000 < 4+60z \Longrightarrow\ z \leq 16\\[/tex]

There are 17: from 4+0*60=4 to 4+16*60=964.

Answer:

17

Step-by-step explanation:

these positive integers are :

4, 64, 124, 184 ... , 964

964 = 4 + (n-1) (60)

964 = 4 + 60n -60

964 = 60n -56

60n = 1020

n = 1020/60

n = 17

so, the number of special integers smaller than 1000 are = 17

D. It is a function, but it is not one-to-one.

Step-by-step explanation:

A function means that each x value has only 1 y value assigned to it.

It is not one-to-one because the x value 0 does not have any y value assigned to it. This is called an asymptote.

Find an equation for the line parallel to 3x+5y-4=0, with the same x-intercept as 2x-3y-6=0.

Answers

Answer:

It is 4y = -3x + 9

Step-by-step explanation:

[tex]3x + 5y - 4 = 0 \\ 5y = - 3x + 4 \\ y = - \frac{3}{4} x + 4[/tex]

since it is parallel, its slope, m is -¾

[tex]2x - 3y - 6 = 0 \\ - 3y = - 2x + 6 \\ y = \frac{2}{3} x - 2[/tex]

at x-intercept, y is zero

[tex]2 = \frac{2}{3} x \\ x = 3[/tex]

therefore

[tex]y = mx + c \\ 0 = ( - \frac{3}{4} \times 3) + c \\ c = \frac{9}{4} [/tex]

equation is

[tex]y = - \frac{3}{4} x + \frac{9}{4} \\ \\ 4y = - 3x + 9[/tex]

At a school camp there is enough food for 150 students for 5 days.
a How long would the food last if there were only 100
students?

Answers

Answer:

If there were only 100 students, there would be enough food for 3 days.

Step-by-step explanation:

Set up an equation:

Variable x = number of days

150/5 = 100/x

Cross multiply:

150 × x = 5 × 100

150x = 500

x = 3.3333...

Round down to a whole number which represents a full day of food.

x = 3

Answers

Relative frequency or experimental probability is calculated from the number of times an event happens, divided by the total number of trials in an actual experiment.

The theoretical probability of getting a head when you flip a fair coin is
1
2
, but if a coin was actually flipped 100 times you may not get exactly 50 heads, although it should be close to this amount.

If a coin was flipped a hundred times, the amount of times a head actually did appear would be the relative frequency, so if there were 59 heads and 41 tails the relative frequency of flipping a head would be
59
100
(or 0.59 or 59%).

Relative frequency is used when probability is being estimated using the outcomes of an experiment or trial, when theoretical probability cannot be used.

For example, when using a biased dice, the probability of getting each number is no longer
1
6
. To be able to assign a probability to each number, an experiment would need to be conducted. From the experimental results, the relative frequency could be calculated.

The more times that an experiment has been carried out, the more reliable the relative frequency is as an estimate of the probability.

Example

Ella rolls a dice and records the number of times she scores a six. Find the relative frequency that Ella rolls a six on her dice.

A farmer is making a circular pen for her pigs. She needs the pen to have a diameter of 26 feet. If fencing costs $32 per foot, which is the closest to the total cost of the fence that the farmer needs to make the pen?
A) $2894.01
B) $ 2765.19
$ 2612.48
D) $ 2578.94​

Answers

Answer:

C

Step-by-step explanation:

circumference= 2* pie*(26/2)

Answer:

[tex]\boxed {\boxed {\sf C. \$ 2612.48 }}[/tex]

Step-by-step explanation:

We are asked to find the cost of the fence a farmer needs to make a pen.

Feet

The fence is used to make a circle. We want to find the cost, but we first need to find how many feet of fence is needed. Essentially, we have to find the perimeter, but this is called the circumference because it is a circle. The formula for calculating circumference is:

[tex]c= \pi d[/tex]

The diameter (d) of the pen is 26 feet and we can use 3.14 for pi. Substitute these values into the formula.

[tex]c=3.14 * 26 \ ft[/tex]

Multiply.

[tex]c= 81.64 \ ft[/tex]

Cost

The farmer needs 81.64 feet of fencing. The cost of fencing is $32 per foot, so we multiply the cost by the feet needed.

[tex]\$32 / ft * 81.64 \ ft[/tex]

The units of feet cancel

[tex]\$ 32 * 81.64[/tex]

[tex]\$2612.48[/tex]

The cost of the fencing is $2612.48 and choice C is correct.

I’ve been stuck on this for days I just need a simple answer

Answers

Answer:

408

Step-by-step explanation:

Surface area formula is A=2(wl+hl+hw)

Substituting these values into the formula you would get

2·(3·8+4·8+4·3)=136

136 accounts for one rectangular prism.

Since you have 3 multiply 136 by 3 which would leave you with 408

Answer:

280 in²

Step-by-step explanation:

The opposite faces are congruent , then surface area (SA ) is

SA = top/ base + front/ back + 2 sides

note for the front/ back and 2 sides we have 3 + 3 + 3 = 9 in

   SA  = 2(8 × 4) + 2(8 × 9) + 2(4 × 9)

         = 2 × 32 + 2 × 72 + 2 × 36

        = 64 + 144 + 72

      = 280 in²

4 A curve has equation y=x^3 - 2x² +5. Find the coordinates of its two stationary points.​

Answers

Answer:

Stationary points are (0, 5) and (4/3, 103/27)

Step-by-step explanation:

At stationary point (turning point), dy/dx :

[tex]y = {x}^{3} - 2 {x}^{2} + 5 \\ \frac{dy}{dx} = 3 {x}^{2} - 4x \\ \\ \frac{dy}{dx} = x(3x - 4)[/tex]

but dy/dx = 0:

[tex]x(3x - 4) = 0 \\ either \: x \: is \: 0 \: and \: (3x - 4) = 0 \\ x = 0 \\ and \\ 3x - 4 = 0 \\ x = \frac{4}{3} [/tex]

let y = x³ - 2x² + 5:

[tex]when \: x \: is \: 0 \\ y = 5 \\ when \: x \: is \: \frac{4}{3} \\ \\ y = {( \frac{4}{3}) }^{3} - 2 {( \frac{4}{3} )}^{2} + 5 \\ \\ y = \frac{103}{27} [/tex]
