Answer: 23
Step-by-step explanation:
La funcion que representa el beneficio obtenido por una empresa si vende x unidades de uno de sus productos es f(x)= -70x^2+2800x-45000. ¿cuantas unidades tiene que vender para maximizar sus beneficios?
Answer:
[tex]20[/tex]
Step-by-step explanation:
La función es
[tex]f(x)=-70x^2+2800x-45000[/tex]
Diferenciando con respecto a [tex]x[/tex] obtenemos
[tex]f'(x)=-140x+2800[/tex]
Igualar con cero
[tex]0=-140x+2800\\\Rightarrow x=\dfrac{2800}{140}\\\Rightarrow x=20[/tex]
Doble derivada de la función
[tex]f''(x)=-140<0[/tex]
Entonces, la función es máxima cuando el número de unidades vendidas, [tex]x=20[/tex],

Slope of the line pls helpppppp
Answer:
[tex] slope(m) = \frac{3}{2} [/tex]
Step-by-step explanation:
Slope (m) = change in y / change in x = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Use any two pairs of values to find the slope. Thus, let's use (-14, 3) and (-12, 6):
Where,
[tex] (-14, 3) = (x_1, y_1) [/tex]
[tex] (-12, 6) = (x_2, y_2) [/tex]
Plug in the values
[tex] m = \frac{6 - 3}{-12 -(-14)} [/tex]
[tex] m = \frac{3}{2} [/tex]

how do I work it out ?
Answer:
x - y = 5
Explanation:
As you can see in the first problem the ration is x to y = 8 to 3. This means for every 8 x values, there are 3 y values. Therefore, x - y should be the same as 8 - 3, which is 5.

Answer: A) 20.9 ; B) 34years
Step-by-step explanation:
Given the following :
AGE (X) - - - - - - - 19 - -20 - - - 21 - - - 22 - - - 23
FREQUENCY (F) - 2 - - 3 - - - - 1 - - - - 4 - - - - 1
A)
MEAN(X) = [AGE(X) × FREQUENCY (F)] ÷ SUM OF FREQUENCY
F*X = [(19 * 2) + (20 * 3) + ( 21 * 1)+(22 * 4)+(23 * 1)]
= 38 + 60 +21 + 88 + 23 = 230
SUM OF FREQUENCY = 2 + 3 + 1 + 4 + 1= 11
MEAN(X) = 230 / 11
X = 20.9
B)
WHEN A NEW PLAYER WAS ADDED :
MEAN (X) = 22
Let age of new player = y
Sum of Ages = 19 + 19 +20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 + y
Number of players = 11 + 1 = 12
Mean(x) = sum of ages / number of players
New mean (x) = 22
x = (230 + y) / 12
22 = (230 + y) / 12
Cross multiply
264 = 230 + y
y = 264 - 230
y = 34 years

The price of a watch was increased by 20% to £162.
What was the price before the increase?
Answer: = £135
Step-by-step explanation:
Original price = 100%
Percentage increase = 20%
New price = 100% + 20% = 120%
If 120% = £162
What about 100% = ?
= (100 x 162) ÷ 120
= 16200 ÷ 120
= £135.

What are all of step to get 3m+4=1
Answer:
Step-by-step explanation:
3m=-3
m=1
Answer:
m = -1
Step-by-step explanation:
3m + 4 = 1
subtract 4 from each side of the equation:
3m + 4 - 4 = 1 - 4
3m = -3
divide both sides by 3:
3m/3 = -3/3
m = -1
Question: Write a word problem that involves ratios. Discuss how you would go about solving this problem.
Answer:
A theater group has 7 boys and 19 girls. What is the ratio of girls to the entire group?
Step-by-step explanation:
One ratio problem would be:
A theater group has 7 boys and 19 girls. What is the ratio of girls to the entire group?
In order to solve this problem we would first need to calculate the total number of individuals in the theater group. We do this by adding the number of boys with the number of girls.
7 + 19 = 26
Now since we know there are 19 girls, the ratio would be 19 girls for every 26 individuals, or in ratio format it would be ... 19 : 26
Alisha hiked a trail that was 9/10 mile and Joseph hiked a trail that was 5/10 mile. How much farther did Alisha hike than Joseph?
Answer:
4/10 or 2/5 of a mile more.
Step-by-step explanation:
Since the denominators are the same, all you have to do is subtract the numerators.
9-5=10.
Therefore, Alisha hiked 2/5 of a mile further than Joseph.
