how do you write the point-slope form of the equation that has a slope of -5/6 point (8,-4)

Answers

Answer 1

Answer:

Step-by-step explanation:

the equation of a line in

point-slope form

is.

xy − y1 = m(x−x1)

where m is the slope and (x1 - y1 ) a point on the line

to calculate m use the

gradient formula

m= y2−y1

     x2−x1

let ( x1 , y1) =( 8, 5) and ( x2 ,y2 ) = (0, −4)

⇒ m= -4-5/0-8= -9/-8= 9/8

using m= 9/8 and (x1- y1) = (8,5) then

y-5= 9/8(x-8)

[tex]-\frac{x^2y^2}{2}[/tex]

Step-by-step explanation:

We have an extremely large equation and are asked to divide it, so let's solve it step-by-step :

Remove the parenthesis to make it easier to read :

[tex]\frac{-3x^3 *2x^3y^4z *3z^2}{4x^3z*3yz*3xyz}[/tex]

Multiply the numerators :

[tex]\frac{-18x^6y^4z^3}{4*3*3x^3yyzzz}[/tex]

Multiply the denominators :

[tex]\frac{-18x^6y^4z^3}{36x^4y^2z^3}[/tex]

Apply the negative rule :

[tex]-\frac{18x^6y^4z^3}{36x^4y^2z^3}[/tex]

Cancel the common factor which is 18 :

[tex]-\frac{x^6y^4z^3}{2x^4y^2z^3}[/tex]

Apply the addition exponent rule :

[tex]\frac{y^4z^3x^{6-4} }{2y^2z^3}[/tex]

Subtract :

[tex]\frac{x^2y^4z^3 }{2y^2z^3}[/tex]

Apply the rule for y :

[tex]\frac{x^2y^{4-2} z^3 }{2z^3}[/tex]

Subtract :

[tex]\frac{x^2y^2z^3 }{2z^3}[/tex]

Cancel the common factor of z^3 :

Answer:

Step-by-step explanation:

8x –3(5x–2)=7–10x

Distribute

8x - 15x +6 = 7-10x

Combine like terms

-7x + 6 = 7- 10x

Add 10x to each side

-7x +10x+ 6 = 7- 10x+10x

3x+6 = 7

Subtract 6 from each side

3x+6-6 =7-6

3x = 1

Divide each side by 3

x = 1/3

the answer is a. 45+2x=180

Answer:

That would be A my good Sir (or ma'am).

Step-by-step explanation:

A triangle has a total of 180 degrees in it , however we already know one side is 45, so we can add that to the solution, we also know that 2 sides are the exact same, so therefore, we will be multiplying our unknown value ( x = 67.5 btw, not so unknown) by 2, and you will always get 180 degrees, thats how you check your answer, also if you sbutract 45 from 180 and divide the product by 2 you will get the value of x ( which is 67.5).

Which of the following points below represents (- 2, - (5pi)/4) the polar grid?

Answers

Answer:

Well, when we have a point in rectangular coordinates (x, y) and we want to write it in polar coordinates (r, θ) the rule we use is:

r = √(x^2 + y^2)

θ = Atg(Iy/xI) + 90°*(n - 1)

where n is number of the quadrant where our point is.

For example, if we are on the second quadrant, we use n = 2.

Now, if instead, we have the point (r, θ) and we want to rewrite it in rectangular coordinates, then the transformation is:

x = r*cos(θ)

y = r*sin(θ)

Now we have the point (- 2, -(5pi)/4) because the first part is negative, this number can not be in polar coordinates (r can not be negative) then we have:

x = -2

y = -(5*pi)/4

Using the first relation, we can find that:

r = √( (-2)^2 + (-5*3.14/4)^2) = 4.4

(rememer that the point (- 2, -(5pi)/4) is on the third quadrant, then we will use n = 3.)

θ = Atg(-(5*pi)/4/-2) + 90°*(3 - 1)= Atg((5*pi)/2) + 180° = 82.7° + 180° = 262.7°

Then the point that represents  (- 2, - (5pi)/4) in polar coordinates is the point:

(4.4, 262.7°)

If instead of degrees, the angle part is written in radians, we have:

180° = 3.14 radians.

262.7° = x radians.

then:

x/3.14 = (262.7)/180

x =  3.14*(262.7)/180 = 4.58 radians.

then the point will be:

(4.4, 4.58 radians)

At a party, the punch bowl is hemispherical, with 2 foot radius and open at the top. The fruit punch weighs 66 pounds per cubic foot. At the beginning of the party the bowl is full to the brim. The rules for serving punch require each person to fill the ladle, raise it exactly 1 foot above the top of the owl (without spilling!), and then pour the punch into a cup at that level. After 10 minutes, 30 people have filled 30 cups, and the punch remaining in the bowl is 4 inches deep. Draw a picture of the situation, and then set up the integral for the work W involved in raising the punch until the punch remaining in the bowl has a depth of only 4 inches. Include all pertinent information in the integral, but do not evaluate the integral.

Answers

Answer:

W = ∫ [−2/3 to 0] 66π (2−y)(1−y²) dy = 2332π/27

Step-by-step explanation:

Vertical cross-section of bowl is a semi-circle of radius 1, centered at (0,0)

x² + y² = 1 (for y ≤ 0)

Bottom of bowl is at y = −1

Top of bowl is at y = 0

When punch is 4 inches deep, this 1/3 ft above bottom of bowl:

y = −1+1/3 = −2/3

So we integrate from y = −2/3 to y = 0

Radius of cross section at height of y is = x = √(1−y²)

Area of cross section at height y is πr²= πx² = π(1−y²)

Since each person is to lift ladle 2 feet above the top of the bowl, then distance = 2−y

W = Σ (density of punch * distance * volume of punch)

W = ∫ [−2/3 to 0] 66 * (2−y) * πr² dy

W = ∫ [−2/3 to 0] 66π (2−y)(1−y²) dy = 2332π/27

Answers

Answer: Sample IQR appears to be a biased estimator since it consistently underestimated the population IQR.

Step-by-step explanation: Checked by Khan Academy

Sample IQR appear to be a biased estimator of population IQR.

What is a biased estimator?

An estimate that deviates from the genuine population value is said to be biased. If the kind and extent of the bias are known, a biased sample may still be informative. When a sample's value matches the actual value of a population parameter, that is an unbiased estimator.

Matilda was curious if sample interquartile range (IQR) was an unbiased estimator of population IQR.

She placed ping pong balls numbered from 0 to 32 in a drum and mixed them well.

The IQR of the population is 16.

She then took a random sample of 5 balls and calculated the IQR of the sample.

She replaced the balls and repeated this process for a total of 50 trials. Her results are summarized in the dot plot below, where each dot represents the sample IQR from a sample of 5 balls.

Sample range appears to be a biased estimator since it consistently underestimated the population range.

The sample ranges appear to be centered below 32.

Therefore, the sample IQR is a biased estimator.

Answer:

D.103.25

Step-by-step explanation:

To find the value of x, you need to know that the height of the donkey and the cactus are proportional and that the shadow of the donkey and cactus are also proportional to each other. Thus, you need to create a proportional and cross multiply to find the value of x.

x/59 = 7/4

After you cross multiply, the equation should look like this:

4x=413

Finally, you divide both sides or numbers by 4 to get 103.25 as your answer! Hope this helps!
