Spheres
Vol = ener
7 cm
Answers
Answer:
Volume of the sphere ( V ) = 1436.02 cm³
Step-by-step explanation:
Explanation:-
Given that the radius of the sphere r = 7 cm
Volume of the sphere
[tex]V = \frac{4}{3} \pi r^{3}[/tex]
[tex]V = \frac{4}{3} \pi (7)^{3}[/tex]
[tex]V = \frac{4}{3} X3.14 X (7)^{3} = 1436.02[/tex]
V = 1436.02 cm³
Volume of the sphere
V = 1436.02 cm³
Answer:1436.8
Step-by-step explanation:
4/3πr^3
Substitute the 7 with the ”r”
4/3xπx7^3
=1436.8 (to 1 decimal place)

A regular polygon has 12 sides find the size of each of its interior angles
Answers
Answer:
150°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° ( n - 2) ← n is the number of sides
Here n = 12, then
sum = 180° × 10 = 1800°
Since there are 12 interior angles, then
size of each interior angle = 1800° ÷ 12 = 150°

For all values of x, f(x) = x^2 + 1 and g(x) = x-5
(a) Show that fg(x) = x^2 - 10x + 26
(b) Solve fg(x) = gf(x)
Answers
Answer:
a) f g(x) = x³ - 5 x² + x -5
b) g(f(x) = x³ - 5 x² + x -5
Step-by-step explanation:
Step(i):-
Given that f(x) = x² + 1 and g(x) = x-5
a)
f(g(x)) = f(x-5) = (x-5)²+1 = x² - 10x +25 +1 = x² - 10 x +26
Step(ii):-
a) f g(x) = f(x) g(x) = (x² + 1 )(x-5) = x³ - 5 x² + x -5
b) g(f(x) = g(x) f(x) = (x-5) (x²+1) = x³ - 5 x² + x -5

Suppose an object is launched from ground level directly upward at 57.4 f/s Write a function to represent the object’s height over time.
Answers
Answer: p(t) = (-16 ft/s^2)*t^2 + (57.4 ft/s)*t
Step-by-step explanation:
We can suppose that the only force acting on the object is the gravitational force, then the acceleration of the object will be equal to the gravitational acceleration.
Then we can write:
a(t) = -32 ft/s^2
Where the negative sign is because this acceleration is downwards.
Now, to get the vertical velocity of the object, we need to integrate over time to get:
v(t) = (-32 ft/s^2)*t + v0
where t represents time in seconds and v0 is the constant of integration, and in this case, is the initial vertical velocity.
In this case, the initial velocity is 57.4 ft/s upwards, then the velocity equation is:
v(t) = (-32 ft/s^2)*t + 57.4 ft/s
To get the position equation we need to integrate over time again, to get:
p(t) = (1/2)*(-32 ft/s^2)*t^2 + (57.4 ft/s)*t + p0
Where p0 is the initial height of the object, as it was launched from the ground, then the initial position is p0 = 0ft.
then the position equation (that is the function that represents the height of the object as a function over time) is:
p(t) = (1/2)*(-32 ft/s^2)*t^2 + (57.4 ft/s)*t
p(t) = (-16 ft/s^2)*t^2 + (57.4 ft/s)*t

The side lengths of a triangle are 5,√3,√28. Is the triangle a right triangle? How would I solve this?
Answers
Legs: 5, √3. Hypotenuse: √28
So your legs are: a and b, and ur hypotenuse is c
a^2+b^2=c^2
Which means
5^2+√3 has to equal to √28^2.
Let’s solve it
5^2+√3^2= √28^2
= 25+3=28
28=28
So that is a right triangle.
First to Answer:
The triangle would be a cute Scalene Triangle!
Here's all that you really can do with solving that
√28 =5.29150262213
√8 = 2.82842712475
Side a = 2.8
Side b = 5
Side c = 5.2
Angle ∠A = 31.788° = 31°47'18" = 0.55481 rad
Angle ∠B = 70.167° = 70°10'0" = 1.22464 rad
Angle ∠C = 78.045° = 78°2'42" = 1.36214 rad
Area = 6.84817
