What is the value of k when k^3 = 1 /125 ?

Answers

Answer 1

Answer:

1/5

Step-by-step explanation:

Finding the unknown value in exponent form:

Prime factorize 125.

      125 = 5 * 5 * 5 = 5³

   [tex]\sf k^3 = \dfrac{1}{125}\\\\ k^3 = \left(\dfrac{1}{5}\right)^3[/tex]

As exponents are same, compare the bases,

 [tex]\sf k = \dfrac{1}{5}[/tex]

         

Answer 2

Answer:

x=1/5

Step-by-step explanation:

[tex]k^3=1/125\\[/tex]

[tex](k^3)^\frac{1}{3} =(\frac{1}{125} )^\frac{1}{3}[/tex]

 [tex]k^3^\frac{1}{3} =\frac{1}{125^\frac{1}{3}}[/tex]

Answer:

x = 30, and the measure of NMO is 64°

Step-by-step explanation:

Since MO bisects LMN, it follows that LMO is congruent to NMO, and the measure of LMN is twice the measure of LMO and of NMO. So we have:

[tex]5x - 22 = 2(x + 34)[/tex]

[tex]5x - 22 = 2x + 68[/tex]

[tex]3x = 90[/tex]

[tex]x = 30[/tex]

So the measure of NMO is equal to the measure of LMO:

[tex]30 + 34 = 64[/tex]

LMO and NMO are 64°.

Answer:

x=30

MO bisects LMN

so LMO = NMO

then LMO+NMO=LMN

the temperature in montreal was -15 degrees. in nyc the temperature was 11 degrees . how many degrees warmer was the temperature in nyc

Answers

First we must state what we know:
Montreal = -15 degrees
NYC= 11 degrees

Then we must come up with an equation to figure out the difference (subtraction) between the two temps.

We use “X” because we don’t know the difference (answer) yet…

X-15=11

We are setting the equation equal to 11 because we are trying to figure out how much warmer NYC is compared to MONTREAL.

Then all we must do is solve for x.

Remember all variables must stay to one side and ANY number that switches sides between the equal sign (=) must switch their signs…


So… because -15 was negative (-) it changed to (+)… BUT if the 15 was positive (+) it WOULD change to negative (-).

find f'(x) when f(x) = (x^2) - 2x. find the equation of the tangent line and the normal line at x=4

Answers

The derivate of a function f(x) is determinated as:

[tex]f^{\prime}(x)=\lim _{h\to0}\frac{f(x+h)-f(x)}{h}[/tex]

For the function

[tex]f(x)=x^2-2x[/tex]

First we have to determine de f ( x + h ) as follow:

[tex]f(x+h)=(x+h)^2-2(x+h)[/tex][tex]f(x+h)=x^2+2xh+h^2-2x-h^{}[/tex]

Then we calculate and simplify the coeficient in the first formula

[tex]\frac{f(x+h)-f(x)}{h}[/tex][tex]\frac{(x^2+2xh+h^2-2x-h^{})-(x^2-2x)}{h}[/tex][tex]\frac{x^2+2xh+h^2-2x-h^{}-x^2+2x}{h}=\frac{h^2+2xh-h}{h}[/tex]

[tex]\frac{h^2+2xh-h}{h}\text{ = }\frac{h(h+2x-1)}{h}=h+2x-1[/tex]So the derivate is:[tex]f^{\prime}(x)=\lim _{h\to0}\frac{f(x+h)-f(x)}{h}=\lim _{h\to0}h+2x-1[/tex][tex]f^{\prime}(x)=0+2x-1[/tex][tex]f^{\prime}(x)=2x-1[/tex]

------------------------------------------------------------------------------------The equation of the tangent:

First you need to know that the derivate of a function is equal to the slope (m) of the tangent of this function

And the equation to thist tangent in a specific point will be find using the next formula:

[tex]y-f(x_0)=m(x-x_0)_{}[/tex]

We have to calculate the slope in the point x =4 using the derivate:

[tex]m=2x-1[/tex][tex]m=2(4)-1=7[/tex]

In the point x=4

Calculate the value of f(x0) substituting in the function the given point x:

[tex]f(4)=4^2-2(4)\text{ = }8[/tex]

Knowing that we put the value of m and f(x0) in the equation of the tangent:

[tex]y-8=7(x-4)_{}[/tex][tex]y-8=7x-28[/tex][tex]y=7x-28+8[/tex]So the equation of the tangent in x= 4 is:[tex]y=7x-20[/tex]

---------------------------------------------------------------------------

The normal line

The slope of the normal line is the opposite of the slope of theu tangent in an espesific point:

[tex]m_n=-\frac{1}{m_t}[/tex]

So in this situation is:

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

The equation of the normal line is given by the next formula:

[tex]y-f(x_0)=m_n(x-x_0)_{}[/tex]

Replacing the data we obtain:

[tex]y-8=-\frac{1}{7}(x-4)_{}[/tex][tex]y-8=-\frac{1}{7}x+\frac{4}{7}[/tex]So the equation of the normal line is:[tex]y=-\frac{1}{7}x+\frac{60}{7}[/tex]

The probabilities of randomly picking a green counter from three different bags are given below.
Order these bags from the lowest probability to the highest probability.

Answers

Answer:

Lowest to highest

7/10 ,  11/15,   4/5

Step-by-step explanation:

Probably the easiest way to do this is to convert each of the fractions to decimals which will clearly indicate which is the highest and which the lowest etc.

4/5 = 0.80

11/15 = 0.73

7/10 = 0.7

0.7 is less than 0.73 is less than 0.80
So 7/10, 11/15, 4/5

However, I am assuming they want you to work with fractions

To compare fractions you have to get all the denominators equal and then compare the numerator

To get a common denominator find the Least Common Multiple of the denominators. This is the lowest number that can be divided by all three denominators

Looking at 5, 15 and 10 we can see that 30 is divisible by each denominator. So that becomes our common denominator

Now multiply each fraction denominator by a factor to make the denominator equal to the common denominator. At the same time multiply the numerator by the same factor

4/5 = (4 x 6) / (5 x 6) = 24/30    Highest

11/15 = (11 x 2) / (15 x 2) = 22/30

7/10 = (7 x 3) / (10 x 3) = 21/30      Lowest

Looking at the numerator alone we can see that 7/10 is the lowest, 11/15 is next lowest and 4/5 the highest

The numeric value of the expression 16 + 4(3q + p) when q = 6 and p = 2 is given by: 96.

How to find the numeric value of a function or of an expression?

To find the numeric value of a function, we replace each instance of the variable in the function by the desired value. This also works for multi-variable functions or expressions, as each instance of each variable will be replaced by their attributed values.

For this problem, the expression is given by:

16 + 4(3q + p)

The attributed values are given by:

q = 6, p = 2.

Hence the numeric value of the expression is found as follows:

16 + 4(3 x 6 + 2) = 16 + 4(18 + 2) = 16 + 4 x 20 = 16 + 80 = 96.

In general, the term "proportion" refers to a part, share, or amount that is compared to a whole. Two ratios or fractions are equal when an equation or a declaration to that effect is utilized.

A polynomial with only one term is called a monomial. An algebraic expression known as a monomial typically has one term, but it can also have several variables and a higher degree.

two cards are selected without replacement from a standard deck of 52 cards. what is the probability that both cards are the same color​ (either both black or both​ red)? round to three decimal places.

Answers

The probability of getting both the card with same color is 0.245

Total No. of cards in a deck = 52

The cards having the same color (either black or red ) = 26 out of 52

                      which is 26/52

The probability of finding a card having the same color without a replacement

                        P = 26/52 x 25/51

[∵ After taking one card, the total no . of cards will be 51 and the card having the same color is 25]

                           = 1/2 x 25/51

                           = 0.5 x 0.49

                        P = 0.245098

4.66 let x represent the number that occurs when a green die is tossed and y the number that occurs when a red die is tossed. find the variance of the random variable (a) 2x − y ; (b) x 3y − 5.

Answers

The variance of each random variable is given as follows:

a) Var(2x - y) = 10.4165.

b) Var(x + 3y - 5) = 20.833.

What is the variance of random variable?

The number that occurs when each dice is thrown is represented by an uniform variable, with bounds a = 1 and b = 6, hence the variance of each variable is calculated as follows:

Var(x) = Var(y) = (6 - 1)²/12 = 2.0833.

When two variables are added, the variance is calculated as follows:

Var(aX + bY) = a²Var(X) + b²Var(Y)

Hence, for item a, the variance is calculated as follows:

Var(2x - y) = 2²Var(x) + (-1)²Var(y) = 4Var(x) + Var(y)

The variances were calculated before, which are both of 2.0833, hence:

4Var(x) + Var(y) = 4 x 2.0833 + 2.0833 = 10.4165.

For item b, the variance is calculated as follows:

Var(x + 3y - 5) = Var(x) + 3²Var(y) + (-1)²Var(-5).

The variance of a constant is of zero, hence Var(-5) = 0, and then:

Var(x + 3y - 5) = Var(x) + 3²Var(y) + (-1)²Var(-5) = 2.0833 + 9(2.0833) = 20.833.
