Answer:
V = 2458.10 cubic inches
Step-by-step explanation:
Volume of a cylinder
V = πr^2h
V - volume of the cylinder
π - pie
r - radius of the cylinder
h - height of the cylinder
Given :
π - 3.142
h - 19.1 inches
d - 12.8 inches
Calculate the radius
Diameter = 2 * radius
Radius = diameter/2
r = 12.8/2
= 6.4 inches
Find the volume
V = 3.142 * (6.4)^2 * 19.1
= 3.142 * 40.96 * 19.1
= 2458.0997 cubic inches
To nearest tenth
V = 2458.10 cubic inches
Answer:
800
Step-by-step explanation:
960 = 2 x 480, so the bacteria will double twice
200 x 2 x 2 = 800
Answer:
2/7
Step-by-step explanation:
To find the this first you need the total number of marbles minus one since the blue marble was taken.
4+5+6-1=14
after one blue marble being picked there are 4 blue left, so the fraction is
4/14 and after being simplified it is 2/7
Answer:
What grade is this?
Step-by-step explanation:
The statements true about the the function f(x) = 2x2 – x – 6 are-
- The vertex of the function is (one-quarter, negative 6 and one-eighth).
- The function has two x-intercepts.
<h3>What is vertex of parabola?</h3>
The vertex of parabola is the point at the intersection of parabola and its line of symmetry.
Now the given function is,
f(x) = 2x^2 – x – 6
Also, it is given that the vertex is located at (0.25, -6) and the parabola opens up, the function has two x-intercepts.
Comparing the given function with standard form,
f(x) = a x^2 bx + c
By comprison we get,
a = 2
b = -1
c = -6
Now, x-coordinate of vertex is given as,
x = -b/2a
put the values we get,
x = -(-1)/2*2
or, x = 1/4
Put the value of x in given function, so y-coordinate of the vertex is given as,
f(1/4) = 2(1/4)² - 1/4 - 6
= -49/6
= -6 1/8
Hence, The statements true about the the function f(x) = 2x2 – x – 6 are-
- The vertex of the function is (one-quarter, negative 6 and one-eighth).
- The function has two x-intercepts.
