Answer:

<em>You have 164 stamps.</em>

Step-by-step explanation:

Let the no. of my stamps be 'x'

Half of x subtracted by 26 = 56

\frac{1}{2} x - 26 = 56

\frac{1}{2} x = 56 + 26 =  82

x = 82 x 2 =  164

Let's check

\frac{164}{2} - 26 = 56

\frac{164}{2} = 56 + 26

164     = 82 x 2

164 = 164!

The answer is correct.

<u>Corrected Question</u>

Create a circle with center A and a radius of your choice. Create a point B on the circle, and find the coordinates of B. Draw the radius AB. What is the slope-intercept form (y = mx + b) of the equation of AB? Show your work.

Answer:

y=0.62x+2

Step-by-step explanation:

In the attached circle drawn using Geogebra

  • Center is at point A(0,2)
  • Point B on the circumference has coordinates (1.7,3.05)
  • Radius of the circle=2 Units

Gradient of AB, m=\dfrac{y_2-y_1}{x_2-x_1} where (x_1,y_1)=A(0,2)$ and (x_2,y_2)=B(1.7,3.05)

m=\dfrac{3.05-2}{1.7-0} \\=\dfrac{1.05}{1.7}\\\\\approx 0.62

Line AB intercepts the y-axis at y=2, therefore: b=2

The slope-intercept form of the line AB (in this case) is therefore:

y=0.62x+2

For every circle center A of radius r and point B chosen on the circumference, the equation of the line AB will be different.

Answer: -14y¹²

Step-by-step explanation:

To find the product, we want to multiply the coefficients and variables.

7y⁹·(-2y³)         [multiply coefficients and variables]

-14y¹²

Therefore, the product is -14y¹².

PLEASE HELPPPPPP!!!!! You are performing an experiment to determine how well plants grow under different light sources. Of the 3
PIT_PIT [208]

The probability that a plant in the experiment receives visible or ultraviolet light is 7/10.

<u>Step-by-step explanation</u>:

The total number of plants in the experiment = 30 plants

Plants that receive visible light alone = 12 plants

Plants that receive ultraviolet light alone = 15 plants

Plants that receive both visible and ultraviolet light = 6 plants

<u>step 1</u> :

<em>Probability = No. of required events / Total number</em>

<u>step 2</u> :

P(visible) = 12 / 30

P(ultraviolet) = 15 / 30

P(both) = 6 / 30

<u>step 3</u> :

P(visible  or ultraviolet) = P(visible)  + P(ultraviolet) - P(both)

                                         = 12/30 + 15/30 - 6/30

                                         = 21/30

P(visible  or ultraviolet) = 7/10
