Answer:
65.41
Step-by-step explanation:
65.3 cm³ is the amount of water filled in the balloon.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that Haley fills a balloon with water until it becomes a sphere with a diameter of 5 centimeters.
We need to find how much water does the balloon contain
It means we need to find the volume of the sphere with diameter 5 centimeters.
Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.
Volume of Sphere=4/3πr³
As diameter is 5
Radius=Diameter/2=5/2=2.5 cm
Volume=4/3×3.14×(2.5)³
=1.33×3.14×15.625
=65.25
=65.3
Hence, 65.3 cm³ is the amount of water filled in the balloon.

ASAP
a=
b=
c=
Answer:
a = 0, b = 6, c = 4
Step-by-step explanation:
Given
f(x) = - x² + x + 6 , then
f(- 2) = - (- 2)² + (- 2) + 6 = - 4 - 2 + 6 = 0 ← a
f(0) = 0 + 0 + 6 = 6 ← b
f(2) = - (2)² + 2 + 6 = - 4 + 2 + 6 = 4 ← c
Answer:
a = 0
b = 6
c = 4
Step-by-step explanation:
f(x) = -x² + x + 6
a = -(-2)² + (-2) + 6 = 0
b = -(0)² + (0) + 6 = 6
c = -(2)² + (2) + 6 = 4

If f and g are functions, then (fog)(x) is always equal to (gof)(x)
true or false
Answer:
False
Step-by-step explanation:
Here is a counter example:
● f(x) = x^2
● g(x) = 3x
● (f○g)(x) = (3x)^2 = 9x^2 (1)
● (g○f)(x) = 3(x^2) = 3x^2 (2)
We can see that (1) and (2) aren't equal to each others.
The given statement is False
The following information should be considered:
[tex]f(x) = x^2\\\\g(x) = 3x\\\\(fog)(x) = (3x)^2 = 9x^2 (1)\\\\(gof)(x) = 3(x^2) = 3x^2 (2)[/tex]
based on the above calculations we can see that equation (1) and equation (2) are not equal to each other.

Anna's salary is four times Emily's salary. They decide to share the cost of a $120 gift card. Anna will contribute four times as much as Emily. How much does each contribute
Answer:
Emily will contribute $24 and Anna will contribute $96
Step-by-step explanation:
From the given information:
Let Emily's salary be x
and let Anna's salary be 4x since Anna's salary is four times Emily's salary.
They were to share the cost of a $120 gift card.
SO, x+4x = 120
5x = 120
x = 120/5
x = 24
Therefore, Emily will contribute x = $24
and Anna will contribute 4x = 4 × $24 = $96
If AB = 20, and BC = 10, what is AC?
Given f(x) = -3x + 5, find f(-6).
Answer:
23
Step-by-step explanation:
Since it says f(x) that means that when we see f(-6) we are substituting x for -6.
This means that the equation will become
f(-6) = -3(-6) + 5
First multiply -3 and -6 (18)
f(-6) = 18 + 5
Next add 18 and 5 (23)
This means that f(-6) = 23
23
This problem is basically asking you to plug in -6 for x and solve using the order of operations (PEMDAS)
[tex]f( - 6) = - 3( - 6) + 5[/tex]
[tex]f( - 6) = 18 + 5[/tex]
[tex]f( - 6) = 23[/tex]
Boyle's Law states that the volume of a fixed amount of gas (at constant temperature) is inversely proportional to the pressure of the gas. A pressure of 46 pounds per square inch (psi) has a volume of 360 cubic feet. What is the particular equation that represents the problem situation?
Step-by-step explanation:
According to Boyle's law,
[tex]$ V \propto \frac{1}{P} $[/tex]
or [tex]$ V = \frac{k}{P} $[/tex] , where k is the proportionality constant
Given that volume is 360 cubic feet and the pressure is 46 psi.
Therefore, replacing V with 360 cubic feet and P with 46 psi in the above equation gives
[tex]$ 360 = \frac{k}{46} $[/tex]
(360)(46) = k
k = 16560
