Step-by-step explanation:

The answer for what does x= is,

x = 2

Answer:

B = (5,4), C = (-5, -4), D = (5, -4), A = (-5, 4)

Step-by-step explanation:

look at x axis first (horizontal), then y axis (vertical)

The coordinates of the points are:

Remember that for a point (x, y), we need to count x units on the horizontal axis, and y units on the vertical axis.

With that in mind, we can see that:

Now, answering the questions:

Which point has coordinates (5, 4)?

Point B

Which point has coordinates (-5, -4)?

Point C

Which point has coordinates (5, -4)?

Point D

Which point has coordinates (-5, 4)?

Given:

Amount after three years = $10000

Rate of interest = 8.2 percent compounded monthly = 0.082

Time = 3 years

To find:

The principal value.

Solution:

Formula for amount is

[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]

where, P is principal, r is rate of interest, n is the number of times interest compounded in an year, t is number of years.

Substitute A=10000, r=0.082, n=12 and t=3 in the above formula.

[tex]10000=P\left(1+\dfrac{0.082}{12}\right)^{12(3)}[/tex]

[tex]10000=P\left(1+\dfrac{41}{6000}\right)^{36}[/tex]

[tex]10000=P\left(\dfrac{6041}{6000}\right)^{36}[/tex]

[tex]10000=P(1.27783)[/tex]

Divide both sides by 1.27783.

[tex]\dfrac{10000}{1.27783}=P[/tex]

[tex]7825.76712=P[/tex]

[tex]P\approx 7825.767[/tex]

Answer:

The confidence interval is 73 ± 4.8

Step-by-step explanation:

Here, we want to construct a 99% confidence interval

Mathematically;

mean ± Z * S.D/√n

From the question

mean = 73

SD = 11.7 ounces

Z score = 2.576 for 99% Confidence interval

n = sample size = 40

Thus;

73 ± (2.576 * 11.7)/√40

73 ± 4.8

So the range of values are;

73 + 4.8 and 73-4.8

= 77.8 and 68.2

The lower boundary is 68.2

The upper boundary is 77.8

$930.76

Step-by-step explanation:

So if you move the decimal in the percentage over to the right by two then you have your sales tax rate in decimal form (0.065), you can then multiply that by the listed price and you'll have about 56.80675 so this number will be the sales tax price, then you may add this to the listed price and your answer will be 930.75675, then once you round up it will be $930.76.

Answer:

Antoine bikes for 16B miles before starting his walk.

Step-by-step explanation:

16 is that speed which is covered in B hours by bike by Antoine

Speed is defined as The rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.

Speed = [tex]\frac{distance}{time}[/tex]

Given,

16B+3.5W = 22 an equation in which B is time covered by bike and W is time covered by walk

Antoine travels partially by bike and partially by walk, and total covered 22

That means 16B is the distance covered by bike, and 16 is its speed.

Hence, 16 is that speed which is covered in B hours by bike.

Answer: Unit rate = 4/35 of a gallon per hour

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

Work Shown:

3 & 1/2 = 3 + 1/2

3 & 1/2 = 6/2 + 1/2

3 & 1/2 = (6+1)/2

3 & 1/2 = 7/2

The faucet drips 2/5 of a gallon in 7/2 hours

2/5 gallon : 7/2 hours

2*(2/5 gallon) : 2*(7/2 hours) ..... multiply both sides by 2

4/5 gallon : 7 hours

(1/7)*(4/5 gallon) : (1/7)*(7 hours) ... multiply both sides by 1/7

4/35 gallon : 1 hour

The unit rate is 4/35 of a gallon per hour.

"Per hour" means "every 1 hour".

7 x 8          56

1 x 7             7

8 x 7           56

now

32               7                     25

-----     -      -----        =        ------

56              56                    56

The amount of solution Janitor has is [tex]\frac{1}{2}[/tex].

It is given that Janitor had 4/7 of a spray bottle of a cleaning solution out of which he used 1/8 of the solution in a day.

We have to find out that how much spray bottle he still have.

What will be the value , 2 times of 1/2 subtracted from 3 ?

The value will be 2.

Janitor had [tex]\frac{4}{7}[/tex] of spray bottle of a cleaning solution.

Amount of solution used by him in a day = [tex]\frac{1}{8}[/tex] of   [tex]\frac{4}{7}[/tex]

= [tex]\frac{4}{56}[/tex] = [tex]\frac{1}{14}[/tex]

The amount of spray bottle which he have now ;

= [tex]\frac{4}{7}[/tex] - [tex]\frac{1}{14}[/tex]

= [tex]\frac{8-1}{14}[/tex]

= [tex]\frac{7}{14}[/tex] = [tex]\frac{1}{2}[/tex].

Thus , the amount of solution he has is [tex]\frac{1}{2}[/tex].

[tex]y=-\,(x+1)^2+3[/tex]

Step-by-step explanation:

Notice that the vertex of the parabola is at (-1, 3), so we can start the expression of the quadratic in vertex form as:

[tex]y=a\,(x--1)^2+3\\y = a\,(x+1)^2+3[/tex]

we can now find the coefficient "a" by using another point the parabola goes through, like for example (0,2):

[tex]y = a\,(x+1)^2+3\\2=a\,(0+1)^2+3\\2=a+3\\a=2-3\\a=-1[/tex]

So the final expression for the parabola in vertex form is:

[tex]y=-\,(x+1)^2+3[/tex]

Answer:

4/3

Step-by-step explanation:

Multiply 2 by 2, and get 4, then we multiply 3 by 2 and get 6.

Since our denominators match, we can add the numerators. 4 + 4 = 8. That gives us the sum, which is 8/6. Then you divide by 2.  So 8/6 / 2 gives you 4/3.

Answer:

4/3 or 1 1/3

Step-by-step explanation:

1. 4/6 + 2/3

2. 4/6 + 4/6          You have to find the LCM (least common multiple) of the two  denominators. In this case it would be 6. You have to multiply 3 by 2 to get 6. What you do to the bottom you also do to the top so you have to also multiply the numerator (2) by 2.

3. 4/3 or 1 1/3       Afterward, you just have to add straight across without changing the denominator and then if you need to simplify you simplify. Without simplifying, you would get 8/6, but, most teachers will mark it as wrong if you don't simplify. You can then change the improper fraction into a mixed number depending on what your teacher wants.
