Finding a parallel slope is really easy:

Anything that has the same slope is parallel. That means the slope needed for finding something parallel is whatever the slope of the original line is. You can find this out by putting everything into the y=mx+b formula; mx is the slope.

When you do this, you should get -y=-6x+1. You cannot have a negative y, so decide everything by -1 and you will get y=6x-1. 6x Is the slope.

Answer:

the answer is -1

Step-by-step explanation:

if you multiply the first equation by -1, you get this:

-3x + 4y = 4

and then you can add that to the second equation and eliminate y

2x + 0y = 16

Answer:

D

Step-by-step explanation:

Answer: Option D.

Step-by-step explanation:

When we want to graph a complex number in a coordinate axis, the real part of the complex number is represented by the x-axis, and the complex part is represented by the y-axis.

in this case, we can see that the coordinates of the point are:

(-2, 2)

Then the complex number is:

Z = -2 + 2*i

Now we need to see which one of the given options is equal to this.

Let's check the real part for every option, so we can discard some of them:

A) real part = -2*cos(135°) = 1.41  (we can discard this option)

B) real part = 2*cos(7*pi/4) = 1.41 (we can discard this option)

C) real part = √2*2*cos(225°) = -2

D) real part = √2*2*cos(3*pi/4) = -2  

So options C or D are the correct one, now let's check the complex part for each one

C) complex part = √2*2*sin(225°) = -2    (we can discard this option)

D) complex part =  √2*2*sin(3*pi/4) = 2

So the correct one is the D option.

Answer:

2.25

Step-by-step explanation:

2.4 - 0.15

Using place value :

2 = Unit (2 wholes)

4 = tenth place ( 4 tenths)

To subtract 0.15

0 wholes ; 1 tenth ; 5 hundredth

1 tenth can be split into 10 separate hundredths

Hence,

For 2.4

We have ;

2 wholes ; 3 tenths and 10 hundredths

Subtracting 0.15 ;0 wholes ; 1 tenth ; 5 hundredth

(2 - 0) wholes = 2 whole

(3 - 1) tenth = 2 tenth

(10 - 5) hundredth = 5 hundredth

Hence, the difference between (2.4 and 0.15) is :

2 whole ; 2 tenth ; 5 hundredth

Which is equal to : 2.25

Answer:

32V/9

Step-by-step explanation:

The length of base leg is 7 cm if altitude leg of a right triangle has a length of ∠32 cm and its hypotenuse measures 9 cm

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given that altitude leg of a right triangle has a length of V 32 cm

Hypotenuse measures 9 cm.

We need to find how long is its base leg.

By pythagoras theorem we need to find the length of base leg.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.

Let x be the length of base leg.

x²+√32²=9²

x²+32=81

Subtract 32 from both sides

x²=81-32

x²=49

Take square root on both sides

x=7

Hence, the length of base leg is 7 cm if altitude leg of a right triangle has a length of ∠32 cm and its hypotenuse measures 9 cm

Answer:

The common ratio is 2.

Step-by-step explanation:

If a given set of elements represents a geometric, each pair of elements must the one and same ratio. That is:

[tex]\frac{n_{i+1}}{n_{i}} = r, \forall\,i\in \mathbb{N}[/tex], [tex]n_{i}, n_{i+1}\in N[/tex]

Where:

[tex]n_{i}[/tex] - i-th element of the given set.

[tex]N[/tex] - Set of elements.

If we know that [tex]n_{1} = 0.45[/tex], [tex]n_{2} = 0.9[/tex] and [tex]n_{3} = 1.8[/tex], then common ration is:

[tex]\frac{n_{2}}{n_{1}} = \frac{n_{3}}{n_{2}} = 2[/tex]

The common ratio is 2.

Answer:

  6/(2+k)

Step-by-step explanation:

The change of base formula is ...

  [tex]\log_a(b)=\dfrac{\log(b)}{\log(a)}[/tex]

Using this, we can take the logarithm base 2 in the change of base formula for the given expression.

  [tex]\log_{20}(64)=\dfrac{\log_2(64)}{\log_2(20)}=\dfrac{\log_2(2^6)}{\log_2(2^2\cdot5)}\\\\=\dfrac{6}{\log_2(2^2)+\log_2(5)}=\boxed{\dfrac{6}{2+k}}[/tex]

In addition to the change of base formula, the usual rules of logarithms apply.

Answer:

account balance at graduation is 674.17

Step-by-step explanation:

given data

deposit money P  =  500

interest rate = 3 % compounded quarterly

we take time period = 10 year ( 2nd grade to 12 grade)

solution

we apply here compound interest formula that is

amount = [tex]P \times (1+\frac{r}{4})^{4t}[/tex]      ..................1

put here value and we get

amount = [tex]500 \times (1+\frac{0.03}{4})^{4\times 10}[/tex]

amount = 674.174

so account balance at graduation is 674.17

Answer:

$694.63

Step-by-step explanation:

The formula is p(1+r/n)^tn. P, or the principal amount, is 500 dollars. R, or the rate as a decimal, is 0.03. N, or the number of times compounded yearly, is 4. T, or the time in years, is 11, since there are 11 years from grade 2 to grade 12. 12-2+1=11. Now, plug in the information given. 500(1+0.03/4)^4*11 = 500(1.0075)^44 = 694.63 dollars, rounded to the nearest cent.

Answer:

0.0721 = 7.21% probability that the mean number of minutes of daily activity of the 8 mildly obese people exceeds 400 minutes

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately Normally distributed with 367 minutes and standard deviation 64 minutes.

This means that [tex]\mu = 367, \sigma = 64[/tex]

A researcher records the minutes of activity for an SRS of 8 mildly obese people.

This means that [tex]n = 8, s = \frac{64}{\sqrt{8}} = 22.63[/tex]

(a) What is the probability that the mean number of minutes of daily activity of the 8 mildly obese people exceeds 400 minutes?

This is 1 subtracted by the pvalue of Z when X = 400. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{400 - 367}{22.63}[/tex]

[tex]Z = 1.46[/tex]

[tex]Z = 1.46[/tex] has a pvalue of 0.9279

1 - 0.9279 = 0.0721

0.0721 = 7.21% probability that the mean number of minutes of daily activity of the 8 mildly obese people exceeds 400 minutes
