Answer:
D: The slope is 3
Step-by-step explanation:
To figure out the slope, which is always a constant, you simply figure out the average displacement using the points we already know. This is described by the equation y2-y1/x2-x1. Let's use the ordered pairs (-3, 2) and (-1, 8) to figure this out.
8-2/-1-(-3) = 6/2 = 3
Another method you could use is to graph the points and figure out how many units y has to go up for every x over, or the "rise over run"
Either way, your slope is 3.

its 3

Hannah made a ramp for her grandfather who was in a wheelchair. The ramp was 10 ft long and it was 5 ft away from the porch steps. How high were the porch steps?
Given :
Length of ramp( Hypotenuse ), l = 10 ft .
Length of base, b = 5 ft .
To Find :
How high were the porch steps.
Solution :
Let, height is h.
By Pythagoras theorem :
[tex]b^2+h^2=l^2\\\\h=\sqrt{l^2-b^2}\\\\h=\sqrt{10^2-5^2}\\\\h = \sqrt{75}\\\\h = 5\sqrt{3}\ ft[/tex]
Hence, this is the required solution.

Answer:
6x-7y=17-----y=6/7x-17/7
6x-11y=-13----y=6/11x-13/11
6x-11y=13----y=6/11x+13/11

The expression (3+i)(1+2i) can be written Jim the form a +bi, where a and b are integers. What are the values of a and b?
Answer:
a = 1
b = 7
Step-by-step explanation:
We start by opening the brackets
We have;
3 + 6i + i - 2
= 1 + 7i
comparing with a + bi
a = 1 and b = 7

A line passes through the point (10,2) and has a slope of 1/2. Write an equation in slope-intercept form for this line.
Answer:
Step-by-step explanation:
y - 2 = 1/2(x - 10)
y - 2 = 1/2x - 5
y = 1/2x - 3
Answer:
Step-by-step explanation:
You can read the slope right away.
y = 0.5x + b 1/2 = 0.5
The point will determine the y intercept
2 = 0.5*10 + b
2 = 5 + b
2-5 = b
b = - 3
The line is y = 0.5x - 3
Explain how the volume of a right cone relates to the volume of a cylinder with the same base
and height. Use diagrams and volume formulas to explain the relationship.
Answer:
its 1/3 of the volume of a cyinder with the same base
Step-by-step explanation:
a pyramid has the same policy with prisms of the same base
Volume is a three-dimensional scalar quantity. If the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.
What is volume?
A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
Assume a cone and a cylinder such that the radius of the base of both the figures is r units, while the height of the cone and cylinder both is h units.
The volume of the cone with radius r units and height h units now can be written as,
Volume of the cone = (1/3) × π × r² × h units³
The volume of the cylinder with a radius of r units and the height of h units now can be written as,
Volume of the Cylinder = π × r² × h units³
Taking the ratio of the volume of the cone and the volume of the cylinder,
Volume of the cone/Volume of the cylinder = (1/3)πr²h units³ / πr²h units³
Volume of the cone/Volume of the cylinder = 1/3
Volume of the cylinder = 3 × Volume of the cone
Hence, if the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.
