Two metal spheres having volume 50 cm cube and 60 cm cube are melted together to form a new sphere .What is the volume of the new Sphere so formed?
Answers
Answer:
[tex]110cm^{3}[/tex]
Step-by-step explanation:
[tex]50cm^{3} + 60cm^{3} = 110cm^{3}[/tex]
The volume of an object stays the same no matter how you shape it, so the volume of the new sphere is the sum of the volume of the two metal spheres assuming that nothing is lost during the process of creating the new sphere.

Answer:
X=-8
Step-by-step explanation:
81^(x-4)=9^3x
(9^2)^(x-4)=9^3x
9^(2x-8)=9^3x
Same base socompare both sides
So 2x-8=3x
2x-3x=8
-x=8
X=-8
So the value of X is -8

A quadratic equation that has X-intercepts of (-2,0) and (8,0), a stretch of 3, and the vertex is a minimum.
a. Factored form equation:
b. Vertex form equation:
c. Standard form equation:
Answers
Answer:
a. y = 3 × (x + 2)(x - 8)
b. y = 3·(x - 3)² - 75
c) y = 3·x² - 18·x - 48
Step-by-step explanation:
The x-intercept of the quadratic equation are (-2, 0), (8, 0)
The stretch of the quadratic equation = 3
We have;
a. The factored form y = 3 × (x + 2)(x - 8)
b. From the vertex form, we have;
y = 3 × (x + 2)(x - 8) = 3·x² - 18·x - 48
y = 3·x² - 18·x - 48
The vertex form a(x - h)² + k
Where;
h = -b/(2·a) = 18/6 = 3
h = 3
k = c - b²/(4·a) = -48 - (18²)/12 = -75
The vertex form 3·(x - 3)² - 75
c) The standard form of the quadratic equation, y = a·x² + b·x + c
The standard form of the quadratic equation is y = 3·x² - 18·x - 48.

b) on a circle with radius 2
c) on a circle with radius 2.5
d) on a circle with radius 4
Answers
Answer:
B) on a circle with radius 2
Step-by-step explanation:
got it right on edge :)
The 4th roots of 16i is located b) on a circle with radius 2
How to determine the location of the fourth root?The complex number is given as:
Number = 16i
Take the fourth root
[tex]Root = \sqrt{16i[/tex]
Take the fourth root of 16
[tex]Root = 2\sqrt{i[/tex]
The number before the radicand represents the circle radius
Hence, the 4th roots of 16i is located b) on a circle with radius 2

-2 / 7 . Crown?
Step-by-step explanation:

Because the positive number is bigger than the negative number on a number line.
Negative numbers are on the left of a number line
Positive numbers are on the right of a number line
If you draw a number line you would go backwards 1 then -3, would become -2 because -2 is greater than -3

A tennis ball was hit into the air. The height of the tennis ball in feet (h) with respect to how far the ball traveled horizontally in feet (d) can be modeled by the quadratic function,
h = -d2 + 8d+4.
Enter the maximum height, in feet, of the tennis ball.
feet
Answers
Answer:
20m
Step-by-step explanation:
Given the height reached by the ball modelled by the equation
h = -d² + 8d+4.
The velocity of the balk at its maximum height is 0. Hence
v = dh/dd = 0
v = -2d + 8
0 = -2d+8
2d =8
d =8/2
d = 4
Substitute d = 4 into the equation to get the maximum height reached
h = -(4)² + 8(4)+4
h =-16+32+4
h = -16+36
h = 20
Hence the maximum height reached by the ball is 20m
