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],

Answer:

Option C is the Correct Answer

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

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]

Answer:

S= 17

Step-by-step explanation:

Δ ABD is a right angle

[tex]S^{2} =8^{2}+15^{2}[/tex]

[tex]S=\sqrt{8^{2}+15^{2} }[/tex]

[tex]S=\sqrt{64+225} =\sqrt{289}[/tex]

[tex]S=17[/tex]

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

Answer:

Y= 57°

Q at both of them 33° each.

57 +90=147

180-147=33

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

2

8 2 | 1 8 9

1 6 4

2 5

Therefore, 180 divided by 82 = 2 with a remainder of 25

2 with a remainder of 25

Decimal form = 2.304878

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:

7/4

Step-by-step explanation:

since 1=4/4

4/4+3/4=7/4

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.

Answer:

the answer is (3, -1)

Step-by-step explanation: Ap3X

Answer      $625:

Step-by-step explanation:

Since the discount is 24% that means that   $475 is 76% of the total

X is the 100% of the price (before sale)

475...............76%

x..........................100%

cross multiplication

76x  =  475x100

76x = 47500

Divide both sides by 76

x= 625

Answer:

6.9 Miles

Step-by-step explanation:

I took the test and got it right,

They are both 6.9 miles apart after one hour if they both hike 4 miles/hour option (B) 6.9 miles is correct.

In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

Miranda and Cyndi start hiking from the same point. Miranda hikes at a heading of 270° or due west, and Cyndi hikes at a heading of 30°

From the isosceles triangle:

h = 4sin30

h = 4(1/2)

h = 2 miles

From Pythagoras theorem:

x² = 4² - h² = 4² - 2²

x = √12

x = 3.46 miles

Total distance = 2×3.46  = 6.9 miles

Thus, they are both 6.9 miles apart after one hour if they both hike 4 miles/hour option (B) 6.9 miles is correct.

Answer:

Step-by-step explanation:

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.
