A circle representing a pool is graphed with a center at the origin. Grant enters the pool at point A and swims over to a friend

who is located at point B. Which equation represents Grant’s path? y = 2 – 4x y = 4 – y = 6 – y = 8 – 2x

From the diagram above you can see that points A and B have coordinates (8,0) and (-4,6), respectively.

The equation of the line passing through the pointa A and B is:

y-y_A=\dfrac{y_B-y_A}{x_B-x_A}(x-x_A).

Then

y-0=\dfrac{6-0}{-4-8}(x-8),\\ \\y=-\dfrac{6}{12}(x-8),\\ \\y=-\dfrac{1}{2}(x-8),\\ \\y=-\dfrac{1}{2}x+4.

Answer: y=4-\dfrac{1}{2}x.

the length of two sides of a triangle are 7 and 10. The length of the third side may be any number __________
pychu [463]

Answer: Greater than 3 but less than 17

Step-by-step explanation: To find the smallest possible side, subtract the largest of the given sides by the smallest. To find the largest possibly side, you add both given sides. In this case, you would subtract 7 from 10 to find the smallest side, which would be 3, and add both sides to find the largest possible side of 17.

Give the parallel cross-section for the following: Cylinder, cone, sphere, and pyramid.
Maurinko [17]

The parallel cross-sections of a cylinder, cone, sphere, and pyramid are a circle, a circle, a circle, and a square.

We are given some solids. Solid geometry, or stereometry, is the traditional name for the geometry of three-dimensional Euclidean spaces in mathematics. Stereometry is concerned with measuring the volumes of various solid figures. The given solids are a cylinder, cone, sphere, and pyramid. We need to find the parallel cross-sections of the given solids. Parallel cross sections are cross sections of a solid that are parallel to each other. A cross section is a straight slice of an object. The parallel cross-sections of a cylinder, cone, sphere, and pyramid are a circle, a circle, a circle, and a square.

Write and solve a system of equations made up of Aiden's and Natalie's lines of best fit that they can use
dezoksy [38]

The catapult arm length for their tennis balls to cover the same distance is 32.3 feet.

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the initial value of y.

Given the equations:

Aiden: y = 2.3x + 160.7

Natalie: y = 3.6x + 202.6

For their tennis balls to cover the same distance:

2.3x + 160.7 = 3.6x + 202.6

1.3x = -41.9

x = -32.3

The catapult arm length for their tennis balls to cover the same distance is 32.3 feet.

A line that includes the point (2,10) has a slope of 9. What is its equation in slope-intercept form
Bumek [7]

Equation: y= 9x+ (y-intercept)

Step-by-step explanation:

equation in slope-intercept form is y=mx+b. <em>m</em> represents the slope of the line, and <em>b</em> represents the y=intercept, which is where the line crosses the y-axis.
