Answer: y = (4/3)x + 2

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

Explanation:

The given equation is y = (-3/4)x - 2. Comparing it to y = mx+b, the slope is m = -3/4

Flip the fraction and the sign to go from -3/4 to 4/3. This is the perpendicular slope. Multiplying the two slopes gets (-3/4)*(4/3) = -1.

Rule: the original slope and perpendicular slope always multiply to -1, assuming neither line is vertical or horizontal.

We'll use the point (x,y) = (3,6) and the perpendicular slope m = 4/3 to find the y intercept b

y = mx+b

6 = (4/3)(3) + b

6 = 4+b

6-4 = b

2 = b

b = 2

The y = mx+b equation becomes y = (4/3)x + 2 which is the slope intercept form of the perpendicular line.

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

Extra info:

If you want to convert to standard form Ax+By = C, then you could do the following steps

y = (4/3)x + 2

3y = 4x + 6 ... multiply everything by 3 to clear out the fraction

3y - 4x = 6

-4x + 3y = 6

4x - 3y = -6 ... multiplying both sides by -1; this is to make A > 0

I am pretty sure it is D. It’s definitely greater or equal to so it’s either B or D

In the figure below, points A, B, and C are on a straight line. What is the measure of angle DBE

Answers

Answer:

<DBE = 120

Step-by-step explanation:

A straight angle (ABC) has 180 degrees.

20 + 40 + x = 180 Combine the left

60 + x = 180 Subtract 60 from both sides.

60-60 + x = 180 - 60

x = 120

The newspaper in Haventown had a circulation of 80,000 papers in the year 2000. In 2010, the circulation was 50,000. With x = 0 representing the year 2000, the graph below models this scenario.

Answers

What number will complete the point-slope equation that models this scenario?

y -50,000 =______(x -10)

A.) -3,000

B.) -2,000

C.) 2,000

D.) 3000

Answer :A.) -3,000

x = 0 representing the year 2000, circulation was 80,000.

x =10 representing the year 2010,circulation was 50,000.

Point slope equation is

$y-y_1=m(x-x_1)$ , where m is the slope and (x1,y1) is one of the point

We have two points, (0,80000) and (10,50000)

Now we need to find slope (m)

$m =(y_2 - y_1)/(x_2-x_1)$ = $(50000-80000)/(10-0) =(-30000)/(10) = -3000$

So answer is y -50,000 =-3000(x -10)

The point P(1,1/2) lies on the curve y=x/(1+x). (a) If Q is the point (x,x/(1+x)), find the slope of the secant line PQ correct to four decimal places for the following values of x: (1) .5 (2) .9 (3) .99 (4) .999 (5) 1.5 (6) 1.1 (7) 1.01 (8) 1.001

Answers

Answer:

See explanation

Step-by-step explanation:

You are given the equation of the curve

$y=(x)/(1+x)$

Point $P\left(1,(1)/(2)\right)$ lies on the curve.

Point $Q\left(x,(x)/(1+x)\right)$ is an arbitrary point on the curve.

The slope of the secant line PQ is

$(y_2-y_1)/(x_2-x_1)=((x)/(1+x)-(1)/(2))/(x-1)=((2x-(1+x))/(2(x+1)))/(x-1)=((2x-1-x)/(2(x+1)))/(x-1)=\n \n=((x-1)/(2(x+1)))/(x-1)=(x-1)/(2(x+1))\cdot (1)/(x-1)=(1)/(2(x+1))\ [\text{When}\ x\neq 1]$

1. If x=0.5, then the slope is

$(1)/(2(0.5+1))=(1)/(3)\approx 0.3333$

2. If x=0.9, then the slope is

$(1)/(2(0.9+1))=(1)/(3.8)\approx 0.2632$

3. If x=0.99, then the slope is

$(1)/(2(0.99+1))=(1)/(3.98)\approx 0.2513$

4. If x=0.999, then the slope is

$(1)/(2(0.999+1))=(1)/(3.998)\approx 0.2501$

5. If x=1.5, then the slope is

$(1)/(2(1.5+1))=(1)/(5)\approx 0.2$

6. If x=1.1, then the slope is

$(1)/(2(1.1+1))=(1)/(4.2)\approx 0.2381$

7. If x=1.01, then the slope is

$(1)/(2(1.01+1))=(1)/(4.02)\approx 0.2488$

8. If x=1.001, then the slope is

$(1)/(2(1.001+1))=(1)/(4.002)\approx 0.2499$

Final answer:

To find the slope of the secant line PQ, we use the formula (y2 - y1)/(x2 - x1) for each given x-value, plug in the coordinates of P and Q, and solve for the slope.

Explanation:

We need to calculate the slope of the secant line passing through points P(1, 1/2) and Q(x, x/(1+x)) for different values of x. The slope of a secant line is calculated using the formula (y2 - y1)/(x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points it passes through. We already have P(1, 1/2), so let's calculate the slope for each given x-value.

For x = 0.5, Q = (0.5, 0.5/(1+0.5)) = (0.5, 1/3).
Slope = (1/3 - 1/2) / (0.5 - 1) = -1/6 / -0.5 = 1/3.
For x = 0.9, perform a similar calculation.
... [Continue for each provided x-value]

After calculating the slope for each x-value, we convert them into a decimal format rounded to four places.

The Museum of Science in Boston has an exhibit in which metal balls drop down a chute, bounce around, and wind up in one of 21 bins. After 1000 balls have dropped, the heights within the bins clearly follow a bell-shaped curve. If the standard deviation is 3 bins, approximately how many balls are in bins 1 through 7?

Answers

This is example of Normal distribution. The central bin is: (21+1)/2=11
If the standard deviation is 3, we have 11-3=8 For bins:1-7 (graph of Normal distribution, or bell-shaped curve) we have 15.87% of all of the balls.
0.1587*1000=158.7.
Answer: We have approximately 159 balls in bins 1 through 7.
