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, 
where 
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:
20cm
Step-by-step explanation:
Frame L&W: 25×20
PictureL&W:20×16
25-20=5
Length of Picture frame=5
Length of Picture frame=4
5×4=20cm²
To find area you multiply length by width
The third one is the correct answer
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.
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
