Answer:
$25 because 100 is half of 500
You are buying bottles of a sports drink mix for a softball team. Each bottle costs $1.19. What function rule models the total cost of a purchase? Evaluate the function for 15 bottles
Answer: f(x) = 1.19x, where f(x) is the total cost, and x is the cost per bottle
Cost of 15 bottles: $17.85
Step-by-step explanation:
This question describes a straightforward relation between cost per bottle, and cost for all the bottles. As such, simply equate one variable to the value of one bottle, and f(x) as the value of every bottle.
Hope it helps :) and let me know if you want me to elaborate.
P.S. f(x) can simply be substituted for "y"
Let
no of bottles be x
.The function is given by
[tex]\\ \sf\longmapsto f(x)=1.19x[/tex]
Now
Bottles=15Cost:-
[tex]\\ \sf\longmapsto f(15)[/tex]
[tex]\\ \sf\longmapsto 1.19(15)[/tex]
[tex]\\ \sf\longmapsto 17.89[/tex]

Which are aspects covered by Bohr’s atomic model?
Electrons can have a measured radius.
Higher orbits have lower energies.
Electrons exist between orbits.
Electrons do not have energy, the energy is determined by the orbit.
The statement (A) Electrons can have a measured radius. and statement (D) Electrons do not have energy, the energy is determined by the orbit are correct.
What is Bohr's atomic model?In the Bohr atomic model, electrons are grouped according to their energy levels. The energy level at which an electron is located determines its energy.
As we know,
The aspects covered by Bohr’s atomic model are:
Electrons can have a measured radius.Electrons do not have energy, the energy is determined by the orbit.Energy is absorbed by electrons as they transition from a lower to a higher energy state. The electron emits energy when it transitions from a higher to a lower energy level. Visible light is one way to view this energy.
Thus, the statement (A) Electrons can have a measured radius. and statement (D) Electrons do not have energy, the energy is determined by the orbit are correct.

Answer: Electrons do not have energy, the energy is determined by the orbit." or A and b
Step-by-step explanation: The correct answer is, "Electrons do not have energy, the energy is determined by the orbit."
In the Bohr model of the atom, electrons are arranged in energy levels. The energy of an electron is determined by the energy level in which it is found.
When electron an the electron moves from a lower to a higher energy level it absorbs energy. When the electron moves from a higher to a lower energy level, it radiates energy. This energy is observed in the form of visible light.
Thus, in the Bohr's model, electrons are arranged in energy levels. The energy level where an electron is found determines its energy.

Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus "twice a number x" can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.

Answer:
x = -36.
Step-by-step explanation:
-1/3x-21/4=27/4
-1/3x = 27/4 + 21/4
-1/3x = 48/4 = 12
x = 12* -3
x = -36.
Peter brought 8 lemons for 6 dollars each lemon was the same price what was the cost for 1 lemon.
Answer:
75 cents
Step-by-step explanation:
We can use a ratio to solve
8 lemons 1 lemon
------------- = ------------
6 dollars x dollars
Using cross products
8x = 6*1
8x = 6
Divide by 8
8x/8 = 6/8
x = .75
One lemon costs .75

{x: x belongs to N and (x-1)(x-2) = 0}, finite set or infinite set?
Explanation:
We have a set of x values such that (x-1)(x-2) = 0. Breaking that down leads to either x-1 = 0 or x-2 = 0 through the zero product property. Solving each of those equations gets us x = 1 and x = 2 as the two items in this set.
So the original set your teacher gave you turns into the roster form {1,2}. There are two items in this set and we can see it's a finite set since it does not go on forever. Note that everything in this set is a natural number.

Answer:
1 9/16
Step-by-step explanation:
F(1/4) means u plug in 1/4 for x
so the equation would be
f(1/4)=1/4^2+2 1/4 + 1
f(1/4)=1/16+1/2+1
f(1/4)= 9/16 +1
f(1/4)= 1 9/16

An engineer is estimating the weight of a steel beam. The actual weight of the beam is 152 pounds. The engineer's estimate is 150 pounds.
Find the absolute error and the percent error of the engineer's estimate. If necessary, round your answers to the nearest tenth.
Answer/Step-by-step explanation:
To find the absolute difference, we simply have to see by how much pounds the estimation was off.
The real measure was 152 pounds, the estimated weight was 150.
D = 152- 150 = 2 pounds.
For the percent of error, we divide the absolute difference (52) by the real value () and we'll get the % of error. So,
%D = 52 / 152 = 0.0034, so 0.34%

Given that f ( x ) = 3 x − 7 and g ( x ) = 3 x + 9 , evaluate f ( g ( 2 ) )
Answer:
38
Step-by-step explanation:
f ( x ) = 3 x − 7
g ( x ) = 3 x + 9
f(g(2))
First find g(2)
g(2) = 3(2)+9 = 6+9 = 15
Then find f(15)
f(15) = 3*15 -7 = 45 -7 =38
