Step-by-step explanation:

-10+sqrt2x+1 = -5

sqrt2x+1 = -5+10

sqrt2x+1 = 5

2x+1 = sqrt5

Answer:

if it ends in 5 then you round up but if it's less than 5 you round down

Step-by-step explanation:

You first have to locate the digit in the rounding place and this digit can be in the ones place, tens place,

hundreds place, thousands place, and so on.

After you locate the digit, look at the

digit to the right of the rounding place.

If the digit to the right of the rounding place is less than 5, we round down and if the digit is greater than or equal to 5, we round up.

Step-by-step explanation:

First differences are ...

First differences are all the same, so we say the terms have a "common" difference. That is characteristic of an arithmetic sequence.

Yes, this sequence is arithmetic.

Answer:

Yes, in all cases the new term is 4 less than the previous term, and so this sequence is arithmetic.

Step-by-step explanation:

If arithmetic, this sequence must have one and only one difference between terms.

33 - 4 = 29

29 - 4 = 25

25 - 4 = 21

Yes, in all cases the new term is 4 less than the previous term, and so this sequence is arithmetic.

Answer:

If Raven's monthly payment were $125, the amount of the loan that she is considering taking out  would be less than $43,205.56.

Step-by-step explanation:

If you think about it this way it may be more simple. If the APR stays constant then a greater payment will result in a greater loan. The opposite is also true meaning a lesser payment will result in a lesser loan. If the amount Raven pays is greater than $145 then the loan will be greater than $43,205.56. If the amount she pays is less than $145 then the loan will be less than $43,205.56. Of the options, only one of these situations will be present. In my case, the correct option was a payment of $125 will result in a lesser loan than $43,205.56.

Step-by-step explanation:

Answer:

  f(2) = g(2) and f(0) = g(0)

Step-by-step explanation:

The notation f(x) = g(x) means that x has the same value in both functions, and the function values are the same:

For x=2:

  f(2) = g(2)

For x = 0:

  f(0) = g(0)

__

If you're searching for solutions to f(x)=g(x), it does you no good to compare the function values for different values of x, as in f(2) = g(0). Such an equality is irrelevant to the problem of finding x such that f(x)=g(x).

The appropriate choice is ...

  f(2) = g(2) and f(0) = g(0)

[tex]tan(D) = \frac{21}{20}[/tex]

Step-by-step explanation:

Step(i):-

Given in triangle DOC

Cos(D) = 20/29

now

[tex]Sec(D) = \frac{1}{Cos(D)} = \frac{1}{\frac{20}{29} } = \frac{29}{20}[/tex]

We Know that trigonometry formulas

[tex]sec^{2}(D) -tan^{2} (D) =1[/tex]

[tex]tan^{2} (D) = sec^{2} (D) -1[/tex]

           = [tex](\frac{29}{20} )^{2} -1[/tex]

          = [tex]\frac{841 -400}{400} = \frac{441}{400}[/tex]

[tex]tan^2(D) = \frac{441}{400}[/tex]

[tex]tan(D) = \sqrt{\frac{441}{400} } = \frac{21}{20}[/tex]

[tex]tan(D) = \frac{21}{20}[/tex]

Answer:

12/-10

Step-by-step explanation:

Any multiple of a fraction is the equivalent of the original fraction, the only difference is that it wont be fully simplified. If we multiply the original fraction (6/-5) by 2, both the numerator and denominator, you will get 12/-10.

Answer:

12/-10

Step-by-step explanation:

6/-5

6×2= 12

-5×2=-10

12/-10

x = amount (in L) of 0.04% solution

y = amount (in L) of 0.2% solution

x + y = 1

Each liter of p% salt solution contributes 0.01*p L of salt to the mixture. In the new solution, the lab tech wants to end up with a concentration of 0.12%, which comes out to 0.0012 * (1 L) = 0.0012 L of salt:

0.0004x + 0.002y = 0.0012

Solve for y in the first equation:

y = 1 - x

Substitute this into the other equation and solve for x, then y:

0.0004x + 0.002(1 - x) = 0.0012

0.0008 = 0.0016x

x = 0.5 L

y = 1 - 0.5 = 0.5 L

Answer:

[tex] \boxed{Volume \: of \: right \: rectangular \: prism = 790 \: {meter}^{3}} [/tex]

Explanation:

Volume of right rectangular prism is same as volume of cuboid

Length = 22.9 meters

Width = 7.5 meters

Height = 4.6 meters

Volume of right rectangular prism = Length × Width × Height

= 22.9 × 7.5 × 4.6

= 22.9 × 34.5

= 790.05 meter³

= 790 meter³

Answer:  b commutative property

Step-by-step explanation: idid the test and i got it right

The property of algebra that allowed jakob simplify the given expression as stated is called; B: The commutative Property

She wants to simplify the expression -3a + 4b + 5a + (-7b)

Now, there are different properties of algebra but the one that jakob used here is called commutative property of algebra.

Commutative property is expressed as an example like;

a + b = b + a

Thus, using commutative property, he arrived at –3a + 4b + 5a + (–7b) = –3a + 5a + 4b + (–7b).

Answer:

The answer is (x+8)(x-3) .

Step-by-step explanation:

First, you have to elaborate out :

[tex] {x}^{2} + 5x - 24[/tex]

[tex] = {x}^{2} - 3x + 8x - 24[/tex]

Next, you can factor out the like terms :

[tex] {x}^{2} - 3x + 8x - 24[/tex]

[tex] = x(x - 3) + 8(x - 3)[/tex]

[tex] = (x - 3)(x + 8)[/tex]

Answer:(x-3)(x+8)

Step-by-step explanation:

x^2+5x-24

We first find two numbers whose product is -24 and whose sum is 5,the two numbers are 8 and -3,we then removed +5x from the equation and replace it with +8x-3x

x^2+8x-3x-24

We factorise

x(x+8)-3(x+8)

We factorise the like terms which is (x+8)

(x-3)(x+8)

  8x +6y -28

Step-by-step explanation:

The outside factor applies to each inside term, so the equivalent expression is ...

Applying the distributive property once again, we can also write the equivalent expression ...

  = 2(4x +3y -14)

Answer:

31 (i.e 3 tens and 1 unit)

Step-by-step explanation:

217 can be split up as,

2 hundreds, 1 tens, and 7 units.

186 can be split up as,

1 hundred, 8 tens and 6 units

If we solve straight we'll have

(2-1)hundreds + (1-8)tens + (7-6)units.

(1-8)tens will give a negative value, complicating the operation.

To make our operation easier we can use the fact that 1 hundred is equal to 10 ten to further split the 217, and it becomes

1 hundred, 11 tens and 7 units.

The operation becomes

(1-1)hundreds + (11 - 8)tens + (7-6)units

= 0 hundred + 3tens + 1 unit

= 3 tens + 1unit

= (3 x 10) + 1 = 31

Answer:

The 95% confidence interval estimate for the population mean life of compact fluorescent light bulbs in this shipment is between 7,255 hours and 7,745 hours.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1-0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].

So it is z with a pvalue of [tex]1-0.025 = 0.975[/tex], so [tex]z = 1.95[/tex]

Now, find the margin of error M as such

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 1.96*\frac{1000}{\sqrt{64}} = 245[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 7500 - 245 = 7255 hours.

The upper end of the interval is the sample mean added to M. So it is 7500 + 245 = 7745 hours.

The 95% confidence interval estimate for the population mean life of compact fluorescent light bulbs in this shipment is between 7,255 hours and 7,745 hours.

A means of the estimate numerical, the variation in that estimate is referred to as the confidence interval, therefore its value is "[tex][7255, 7745][/tex]".

[tex]95\%[/tex] C.I. for a mean lifetime is given by

[tex]= [ \overline{X} - \tau_{0.975} \frac{\sigma}{\sqrt{n}} , \overline{X} + \tau_{0.975} \frac{\sigma}{\sqrt{n}} ][/tex], where

[tex]\bar{X}[/tex] (sample mean) [tex]= 7500[/tex]

[tex]\sigma[/tex] (standard deviation)[tex]= 1000[/tex]

[tex]n = 64[/tex]

by putting the value into the above-given formula we get the value that is  [tex]= [7255, 7745].[/tex]

Answer:

The cutoff rate that would separate the highest 2.5​% of currency​ A/currency B​ rates is 1.92.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 1.832

Standard deviation = 0.044

Top 2.5%

95% of the measures are within 2 standard deviation of the mean.

Since the normal distribution is symmetric, this 95% goes from the 50 - 95/2 = 2.5th percentile to the 50 + 95/2 = 97.5th percentile.

The 97.5th percentile is the cutoff for the highest 2.5% of currency​ A/currency B​ rates, and it is 2 standard deviations above the mean.

1.832 + 2*0.044 = 1.92

The cutoff rate that would separate the highest 2.5​% of currency​ A/currency B​ rates is 1.92.
