Answer:
1 and 1/2
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The x-intercepts of a parabola are where the parabola intersects the x-axis on its graph. There are a number of ways to find the x-intercepts of a parabola, and each one is usually specific to each situation.
In the case, when you are given the graph, the easiest way to find x-intercepts is to identify points at which parabola intersects the x-axis.
From your graph, parabola intersects x-axis at two points: (-5,0) and (-4,0)
Answer:
x=91, y=91, z=39
Step-by-step explanation:
the angles add up to 180 so find the difference ex. 51+38=89, 180-89=91 so x is 91
Answer:
Option A. The volume of the sphere is multiplied by 1/343.
Step-by-step explanation:
The volume of a sphere can be obtained by the following formula:
V = 4/3πr^3
Let the initial volume (V1) of the sphere be:
V1 = 4/3πr^3 = (4πr^3)/3
Now, if we multiply the radius by 1/7, then the new volume (V2) of the sphere will be:
V2 = 4/3 x π x (1/7r)^3
V2 = 4/3 x π x 1/343r^3
V2 = (4πr^3)/1029
Now we determine the ratio of V2 : V1 as shown below:
V2/V1 = (4πr^3)/1029 ÷ (4πr^3)/3
V2/V1 = (4πr^3)/1029 × 3/(4πr^3)
V2/V1 = 3/1029
V2/V1 = 1/343
V2 = 1/343 x V1
Therefore, the volume of the sphere is multiplied by 1/343.
