Well then let's try and find the pattern!
When we add 1 through 10, we can also say that we're adding all of these values together:
1 + 10 = 11
2 + 9 = 11
3 + 8 = 11
4 + 7 = 11
5 + 6 = 11
So we can also say that this is like multiplying 11 * 5 = 55
If we add up to 100, we can see that it's like multiplying 101 * 50 = 5050
From this, we can get an equation:
(x + 1) * (x/2)
So let's plug in 10000 into this equation:
(x + 1) * (x/2)
(10000 + 1) * (10000/2)
10001 * 5000 = 50005000
Answer:
C 50005000

Answer:
Step-by-step explanation:
y=ax^2+bx+c
a parabola open down when a is negative
y intercept equal 3 when x=0 then y=c=3
vertical stretch : is a stretch away from the x-axis
the equation is (-0.5x^2+4x+3)
i hope it helps
Use sine cosine and tangent to find the answer. Sine=opposite/hypotenuse
Cosine= adjacent/hypotenuse tangent= opposite/adjacent. This should help you find your answers.
Answer:
D
Step-by-step explanation:
Calculating the volumes of both solids
Volume of a cube = s³ ( where s is the side length )
here s = 10, hence
V = 10³ = 10 × 10 × 10 = 1000 in³
Volume of a cylinder = area of base × height
Area of circular base = πr²
here r = 10 and h = 12, hence
V = π × 10² × 12 = 1200π ≈ 3769 .9 in³
The volume of the cylinder is greater than the volume of the cube → D
