Answer:

8x^4

Step-by-step explanation:

x^2*x*8*x

=8*x^4

=8x^4

I believe I am accurate! So sorry if I am mistaken,  I couldn't see the problem perfectly. Also, make sure to have the picture blurry it was very difficult to calculate the correct interpretation (even if I am correct).

Answer: 20

Step-by-step explanation:

The base square is 4 x 4, which is 16. That part is easy, but the other part needs more thinking.

We have two more visible full squares, which we can add on to our 16, putting it at 18. But that half squares, we have 4 total have squares. We know that 1/2 + 1/2 = 1

So, 1/2 + 1/2 + 1/2 + 1/2 = 2.

We eventually get 16 (original square) + 2 (two other full squares) + 2 (half squares) resutling in 20.

3x-2y+4z-x+5y+3x-2y+4z-x+z

First, reorder(I put the like terms in parenthesis to help you see the work better).

(3x+3x-x-x)+(5y-2y-2y)+(4z+4z+z)

Now, we add/subtract like terms.

(6x-2x)+(5y-4y)+(8z+z)

Lastly, we combine.

4x+y+9z

Answer:

41. f⁻¹(x) = -9x + 4

43. m⁻¹(x) = ∛(x-2)/4  

Step-by-step explanation:

41. y = (4-x)/9

swap x and y: x = (4-y)/9

solve y: 9x = 4-y

             y = -9x + 4

45. y = 4x³+2

     x = 4y³+2

     4y³ = x-2

     y³ = (x-2)/4

     y = ∛(x-2)/4

Let you do 42 and 46 by yourself

Answer:

The initial mass of the sample was 16 mg.

The mass after 5 weeks will be about 0.0372 mg.

Step-by-step explanation:

We can write an exponential function to model the situation.

Let the initial amount be A. The standard exponential function is given by:

[tex]P(t)=A(r)^t[/tex]

Where r is the rate of growth/decay.

Since the half-life of Palladium-100 is four days, r = 1/2. We will also substitute t/4 for t to to represent one cycle every four days. Therefore:

[tex]\displaystyle P(t)=A\Big(\frac{1}{2}\Big)^{t/4}[/tex]

After 12 days, a sample of Palladium-100 has been reduced to a mass of two milligrams.

Therefore, when x = 12, P(x) = 2. By substitution:

[tex]\displaystyle 2=A\Big(\frac{1}{2}\Big)^{12/4}[/tex]

Solve for A. Simplify:

[tex]\displaystyle 2=A\Big(\frac{1}{2}\Big)^3[/tex]

Simplify:

[tex]\displaystyle 2=A\Big(\frac{1}{8}\Big)[/tex]

Thus, the initial mass of the sample was:

[tex]A=16\text{ mg}[/tex]

5 weeks is equivalent to 35 days. Therefore, we can find P(35):

[tex]\displaystyle P(35)=16\Big(\frac{1}{2}\Big)^{35/4}\approx0.0372\text{ mg}[/tex]

About 0.0372 mg will be left of the original 16 mg sample after 5 weeks.

Answer:

John is preparing to retire, and he knows he’ll receive a pension from his company. The pension will pay John $25,000 per year for 20 years. A lump-sum payment of $500,000 today is also an option for John, and the account John would use for that money would pay interest of 3% per year, compounded annually.

Since the present value of all the yearly pension payments is "$371,937"

, John should choose the "lump-sum"  option for his pension.

Step-by-step explanation:

Answer:

2.954545454

Step-by-step explanation:

65/22 = 65 divided by 22. That is how many times 22 can go into 65

A decimal number has a decimal point in it. That is a whole number and some fraction that could be in tenths or otherwise.

65 is the numerator,

22 is the denominator

Using a calculator

65/22 = 2.9545454

8

Step-by-step explanation:

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data:

85, 91, 83, 78, 79, 64, 81, 97

Ordered data : 78, 79, 81, 83, 85, 91, 97

Mean:

Σx / n =

n = sample size = 8

(64+78+79+81+83+85+91+97) / 8

= 658 / 8

= 82.25

Median = 1/2(n+1)th term

1/2(8+1)th term = 1/2 * 9 = 4.5th term

(4th term + 5th term) /2 = (81 + 83) / 2 = 82

Mode = 85, 91, 83, 78, 79, 64, 81, 97

Outlier:

Lower = Q1 - 1.5(IQR)

Upper = Q3 + 1.5(IQR)

Using a calculator :

Q1 = 78.5 ; Q3 = 88 ;

IQR = (Q3 - Q1)

(88 - 78.5) = 9.5

Outlier :

78.5 - 1.5(9.5) = values < 64.25

88 + 1.5(9.5) = values > 102.5

Hence. Outlier is 64

Removing the Outlier :

Data = 78, 79, 81, 83, 85, 91, 97

Mean = 84.85

Median = 83

Based on the result, the median is the best measure of central tendency for the data:

Answer:

These are confusing Beth , b/c you have to remember that they will add to 100%

Step-by-step explanation:

so

green = 3*  yellow

100% = green + yellow + 35% + 25%

100% = 3* yellow + yellow +60%

40% = 4* yellow

10% = yellow

30% = green

there are 14 purples in the bag , which is 35% of total

14/.35 = 40

there are a total of 40 pins

so

4    are yellow  (10% of 40  or 40* 0.1)

12 are green    (30% of 40  or 40*0.3)

14  are purple  (35% of 40 or 40*0.35)

10  are grey  (25% of 40  or 40*0.25 )

Answer:

I think c, - 1.8 is the answer

-1.6 (c)

My reasoning behind this is that the number would be logical considering the fact that the point is close to 0. Also, I ruled out the other choices, and here's how I did it:

I know that A is not the answer because that would make it farther back on the number line and the point B is closer to 0 than it is to 3.8 so, I know that A is not correct.

I know that B is not the answer because -5.23 would be farther behind point A which rules it out entirely.

I know that D is not the answer because 0.1 would be right after point c (0) meaning that the point can be ruled out right away.

That leaves the only logical answer to be C because it is closer to 0 but still in between points A and B.

Hope this helps and have a nice day.

Answer:

6 cm

Step-by-step explanation:

First find the height of 1 foot by doing 1/6 = 1.66. Then multiply that by the height of the robot. 1.66 x 36 = 6.

Answer:

i think it is A

Step-by-step explanation:

A 216

because if 1cm is 6 ft then you would have to do 6ft 36 times example 6×36 =216

im not sure im not good at math but i tried to help :(

Answer:

yes

Step-by-step explanation:

the Pythagorean Theorem states that

[tex]a^2+b^2=c^2[/tex]

or to me more specific the two shorter side lengths squared added together equal the hypotenuse squared

So basically what im saying is that if this is a right triangle then

[tex]4^2=\sqrt{6} ^2+\sqrt{10} ^2[/tex]

[tex]4^2=16\\\sqrt{6} ^2=6\\\sqrt{10}^2=10\\10+6=16\\16=16[/tex]

The following statement is true therefore it is a right triangle :)

Given:

The measure of three sides of a triangle are 8, 7 and 14.

To find:

The measure of the angle opposite the side of length 8.

Solution:

According to the Law of Cosine:

[tex]\cos A=\dfrac{b^2+c^2-a^2}{2bc}[/tex]

Let a=8, b=7 and c=14, then by using Law of Cosine, we get

[tex]\cos A=\dfrac{7^2+14^2-8^2}{2(7)(14)}[/tex]

[tex]\cos A=\dfrac{49+196-64}{196}[/tex]

[tex]\cos A=\dfrac{181}{196}[/tex]

Taking cos inverse on both sides.

[tex]A=\cos^{-1}\dfrac{181}{196}[/tex]

[tex]A=22.561328[/tex]

[tex]A\approx 22.6[/tex]

Therefore, the measure of the angle opposite the side of length 8 is 22.6 degrees.

Answer: 56

Step-by-step explanation:

Answer:

x = 55.94 degrees

Step-by-step explanation:

(to find x, use cosine) (cos = [tex]\frac{adjacent}{hypothenuse}[/tex])

First step: write out the equation

⇒ cos x = [tex]\frac{14}{25}[/tex]

Second step: find out what [tex]\frac{14}{25}[/tex]  is

⇒ [tex]\frac{14}{25}[/tex] = 0.56

Third step: find out what the cos-1 of 0.56 is

⇒ cos-1 of 0.56 = 55.94

Fourth step: you got your answer

⇒ x = 55.94

Answer:

It is better to buy 20 g of flour 3 for 3.50

Step-by-step explanation:

It is given that 20g of 3 for 3.50

It means 3 packets of 20 g is 3*20 =60

So, 60g  is for 3.50

So, 1 g =[tex]\frac{3.5}{60}[/tex]=0.05833 per gram.

Now, let's find unit rate for 40 g of 2 for 9.

2 packets of 40 gram = 2* 40 =80 grams

So, 80 grams costs 9

So, 1 gram =[tex]\frac{9}{80}[/tex] =0.1125

So, it is better to buy 20 g of flour 3 for 3.50
