If ax – b = 0 and a #0, then x =
Answer:
x = [tex]\frac{b}{a}[/tex]
Step-by-step explanation:
Given
ax - b = 0 ( add b to both sides )
ax = b ( divide both sides by a )
x = [tex]\frac{b}{a}[/tex]

Which of the following functions would give the population Plt) as a function
of t, in years, given that the initial population is 2,500 and that the population
is growing at an annual rate of 4%?
(1) P(t)=2500(0.96)
(3) P(t)=2,500(1.04)
(2) P(t)=(1.04) +2,500
(4) P(t)= 1.04t +2,500
Answer:
[tex]P(t)=2500(1.04)^t[/tex]
Step-by-step explanation:
None of your proposed answers has an exponent t.
Here's the logic behind the answer:
Year 0: pop. = 2500
Year 1: pop. = 2500(1.04) That is 104% of the previous year's pop.
Year 2: pop. = 2500(1.04)(1.04) = 2500(1.04)^2
Year 3: pop. = 2500(1.04)^2 x (1.04) = 2500(1.04)^3
See the pattern? The exponent matches the year number.

Juana depositou em sua conta bancária as importancias de R$500.00 e R$350,00 e R$450.00 o SALDO DE SUA CNTA CORRENTE REPRESENTDADO COM NUMEROS INTEIROS É DE QUANTO?
Responder:
R $ 1300
Explicação passo a passo:
Dado que :
Quantia depositada:
Primeiro depósito = $ 500
Segundo depósito = $ 350
Terceiro depósito = $ 450
O valor total depositado é a soma de todos os três depósitos feitos e constitui o saldo atual da conta.
Primeiro depósito + segundo depósito + terceiro depósito
$ (500 + 350 + 450)
= $ 1300

To determine a student’s overall test score for the semester, Ms. Lopez throws out the lowest test score and takes the average of the remaining test scores. Victor earned the following test scores in Ms. Lopez’s class this semester: 62, 78, 83, 84, and 93. What overall test score did Victor earn in Ms. Lopez’s class this semester?
67.6
67.6
80.0
80.0
83.0
83.0
83.5
83.5
84.5
Answer:
80%
Step-by-step explanation:
I'm assuming you want the average of the class.
62 + 78 + 83 + 84 + 93
= 400
400/5
= 80
Therefore Victor's overall test score is 80%

Answer: The answer is 280 ft.
Step-by-step explanation:
divide the green area into a triangle and a rectangle so it's easier to calculate. Then find the area of the rectangle by multiplying 14 times 16. That should get you 224. Then, find the area of the tringle by multiplying 14 times 18, times 1/2. That will get you 56. If you add 56 to 224, that gets you 280.
Find the measure of arc DB in OP.
mDB=
Answer:
90
Step-by-step explanation:
First of all you have to know that when 2 lines are perpendicular to each other,they produce a 90° angle, therefore DP||TD. Then you should remember that the measure of an arc is the same as the measure of the angle. So angle DB is 90°.

The question is: 6f^3 - 8f^2 + 20 - 15f
The answer is supposed to be; (2f^2 - 5)(3f - 4)
Pls show your work
Answer:
Step-by-step explanation:
Factor 6f3−8f2+20−15f
6f^3−8f^3−15f
=(3f−4)(2f2−5)
Answer:
(3f−4)(2f^2−5)
Find the group you want to factor, such as in the first parenthesis, you remove 3f from the whole equation, and end up with 3f-4. You take the end value, and group it with -5. You will then end up with 2f^2 -5.

What is the gravitational potential energy of a 2.5 kg object that is 300 m above the surface of the earth
Answer:
7350 JStep-by-step explanation:
The gravitational potential energy of a body can be found by using the formula
GPE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
We have
GPE = 2.5 × 9.8 × 300
We have the final answer as
7350 JHope this helps you
Kelly's team won 85% of the games they played in a season. The team lost 12 games. How many games did Kelly's win in the season?
Answer:
68 games
Step-by-step explanation:
Given data
out of 100%
they lost 15%
Let the total game played be x
so
15/100*x= 12
0.15x= 12
x= 12/0.15
x= 80 games
the total games played is 80
Hence the games won
=total games-games lost
=80-12
=68 games

Al cine paraíso fueron el sábado 1.350 espectadores y el domingo 1.120 cuánto se recaudo si cada entrada costaba 540?
Answer:
1,333,800
Step-by-step explanation:
Spectators on Saturday = 1,350
Spectators on Sunday = 1,120
Total spectators = 1,350 + 1,120 = 2,470
Price per ticket = 540
So, we can calculate the total amount collected by using following formula,
Total amount collected = Total spectators × Price per ticket
By putting value, we get
= 2,470 × 540
= 1,333,800

Which statement identifies how to show that j(x) = 11.6ex and k(x) = In (StartFraction x Over 11.6 EndFraction) are inverse functions?
Answer:
The answer is "It must be shown that both [tex]j(k(x))\ and \ k(j(x))=x[/tex]"
Step-by-step explanation:
Given:
[tex]j(x) = 11.6 e^{x} \\\\k(x) =\ln\frac{x}{11.6}[/tex]
To show that both are equal functions, and show that both[tex]j(k(x))\ and\ k(j(x)) =x,[/tex]
For [tex]j(k(x));[/tex]
[tex]j(k(x)) = j[(\ln \frac{x}{11.6})]\\\\j[(\ln (\frac{x}{11.6})] = 11.6e^{\ln (\frac{x}{11.6})}\\\\j[(\ln \frac{x}{11.6})] = 11.6(\frac{x}{11.6})\\\\[/tex](The natural logarithm is canceled by exponential function)
[tex]j[(\ln \frac{x}{11.6})] = 11.6 \times\frac{x}{11.6}\\\\j[(\ln \frac{x}{11.6})] = x\\\\j[k(x)] = x\\\\for\ \ k[j(x)]:\\\\k[j(x)] = k[11.6e^x]\\\\k[11.6e^x] = \ln (\frac{11.6e^x}{11.6})\\\\k[11.6e^x] = \ln(e^x)[/tex]
Its natural logarithm leaving x will nullify expanding universe.
[tex]k[11.6e^x] = x\\\\k[j(x)] = x[/tex]
In the question, it is seen that[tex]j[k(x)] = k[j(x)] = x[/tex], shows that the functions [tex]j(x) = 11.6 e^{x} \ and \ k(x) = \ln \frac{x}{11.6}[/tex] is inverse functions.

Marcus is rolling a number cube with sides labelled 1 to 6 .find the probability it will show 10
Answer:
Probability of getting number 10 = 0
Step-by-step explanation:
Given;
Total sides of cube die = 6
Find:
Probability of getting number 10
Computation:
Total number of cube = 1, 2, 3, 4, 5, 6
Favorable outcome for 10 = 0
Probability of an event = Favorable outcome / Number of outcomes
Probability of getting number 10 = 0 / 6
Probability of getting number 10 = 0
