Answer:

x = 2,24 cm

y = 17,96 cm

Step-by-step explanation:

The volume of a cube is:

V = x²*y      where  x is the side of the square base and the height of the cube

V = 90 cm³

And the surface area of the cube is:

S(c)  =  Area of the base (A₁ ) + Lateral area (A₂)

A₁  = x²       and  V = x²*y     then  y = 90/x²

Therefore total cost is:

Cost of the top plus bottom  C₁ =  0,20 * 2 * x²  C₁ = 0,4*x²

Lateral cost (C₂)  is    C₂ = 0,10 * x*y    then  C₂ =  0,10*x ( 90/x²)    C₂ = 9/x

C(x) = 0,4*x² + 9/x

We take derivatives on both sides of the equation to get:

C´(x) = 0,8*x  -  9/x²

C´(x) =  0     0,8*x  - 9/x²  = 0

0,8*x³ - 9  = 0

0,8 * x³  = 9

x³  =  11,25

x = ∛ 11,25

x  =  2,24  cm

And   y  =  90 / 5,01        y  =  17,96 cm

Answer:

3/6=1/2

Step-by-step explanation:

1/6+1/6+1/6=3/6

The most simplified answer is 1/2

The fraction 1/6 + 1/6 +1/6 is equals to the 1/2 after adding them all.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

We have:

= 1/6 + 1/6 +1/6

Taking LCM of 6, 6, and 6 is 6

= (1+1+1)/(6)

= 3/6

Divide by 3 on numerator and denominator.

=1/2

Thus, the fraction 1/6 + 1/6 +1/6 is equals to the 1/2 after adding them all.

Answer:

-r^4+3r^3-21r+49

Step-by-step explanation:

(−r2+3r+−7)(r2+−7)

=(−r^2)(r^2)+(−r^2)(−7)+(3r)(r^2)+(3r)(−7)+(−7)(r^2)+(−7)(−7)

=−r4+7r2+3r3−21r−7r2+49

=−r4+3r3−21r+49

The given polynomial in the standard form is -

- r⁴ + 3r³ - 21r + 49

Given is the following polynomial -

(- r² + 3r - 7)(r² - 7)

We can write the polynomial as -

(- r² + 3r - 7)(r² - 7)

Expanding, we get -

r²(- r² + 3r - 7) - 7(- r² + 3r - 7)

- r⁴ + 3r³ - 7r² + 7r² - 21r + 49

- r⁴ + 3r³ - 21r + 49

Therefore, the given polynomial in the standard form is -

- r⁴ + 3r³ - 21r + 49.

Answer:

E’ is (11,-1)

Step-by-step explanation:

Here, we want to get the new coordinates of E

The translation is 4 units right ( add 4 to x-value) and 3 units down ( subtract 3 from y-value)

So for E, we have

(7 + 4, 2-3)

= (11, -1)

I would say D

Answer:

John ate 7/12 more of the candy than Sandy.

Step-by-step explanation:

3/4 is equivalent to 9/12.

1/6 can be expressed as 2/12.

Step 3: 9/12 - 2/12 = 7/12.

Now that they have the same denominators, perform the subtraction process.

Then,John ate 7/12 more of the candy than Sandy.

Answer:

2

Step-by-step explanation:

With regards to the above, we can sum up the foods ate together by the 5 cats, then we have;

= 1/5 + 1/5

= 2/5

Then we can multiply the value above by the 5 cats

= 2/5 × 5

= 10/5

= 2

The cats eat 2 foods together.

Answer:

La distancia recorrida por el móvil es 240 metros.

Step-by-step explanation:

Puesto que el móvil experimenta movimiento rectilíneo uniformemente acelerado, la distancia recorrida es determinada por las siguientes ecuaciones cinemáticas:

[tex]\Delta x = v_{o}\cdot t + \frac{1}{2}\cdot a\cdot t^{2}[/tex] (1)

[tex]v = v_{o} + a\cdot t[/tex] (2)

Donde:

[tex]\Delta x[/tex] - Distancia recorrida, medida en metros.

[tex]v_{o}[/tex] - Velocidad inicial, medida en metros por segundo.

[tex]v[/tex] - Velocidad final, medida en metros por segundo.

[tex]a[/tex] - Aceleración, medida en metros por segundo al cuadrado.

[tex]t[/tex] - Tiempo, medido en segundos.

En (2) despejamos el tiempo:

[tex]a = \frac{v-v_{o}}{t}[/tex]

Si aplicamos esta ecuación en (1):

[tex]\Delta x = v_{o}\cdot t + \frac{1}{2}\cdot \left(\frac{v-v_{o}}{t} \right)\cdot t^{2}[/tex]

[tex]\Delta x = v_{o}\cdot t + \frac{1}{2}\cdot (v-v_{o})\cdot t[/tex]

[tex]\Delta x = \frac{1}{2}\cdot v_{o}\cdot t+\frac{1}{2}\cdot v\cdot t[/tex]

[tex]\Delta x = \frac{1}{2}\cdot (v_{o}+v)\cdot t[/tex] (3)

Si sabemos que [tex]v_{o} = 0\,\frac{m}{s}[/tex], [tex]v = 60\,\frac{m}{s}[/tex] and [tex]t = 8\,s[/tex], entonces la distancia recorrida es:

[tex]\Delta x = \frac{1}{2}\cdot \left(0\,\frac{m}{s}+60\,\frac{m}{s}\right) \cdot (8\,s)[/tex]

[tex]\Delta x = 240\,m[/tex]

Answer:

100 miles is the answer

Step-by-step explanation:

3 inches = 20 miles

15/3 = 5

5 x 20

= 100 miles

========================================================

Work Shown:

(3 inches)/(20 miles) = (15 inches)/(x miles)

3/20 = 15/x

3*x = 20*15

3x = 300

x = 300/3

x = 100

Therefore, 15 inches on the map correspond to 100 miles in real life.

-------------------

We could approach the problem like this:

3 inches = 20 miles

5*(3 inches) = 5*(20 miles)

15 inches = 100 miles

In the second step, I multiplied both sides by 5 to turn the "3 inches" into "15 inches".

Answer:

{y | y > 12}

Step-by-step explanation:

just took the test

Step-by-step explanation:

f(x) = x² + 6x + 12

= (x² + 6x + 9) + 3

= (x + 3)² + 3.

Since a² >= 0 for all real values of a,

(x + 3)² >= 0 for all real values of x,

(x + 3)² + 3 >= 3 for all real values of x.

Hence f(x) >= 3. (Shown)

Answer:

The value of given expression is 6.

Step-by-step explanation:

Given expression is;

[tex]\sqrt{5x^2-(-x^4)}[/tex]

We have to solve the expression when x = -2

Putting x = -2 in the given expression,

Solution = [tex]\sqrt{5(-2)^2-(-(-2)^4))}\\[/tex]

Solution = [tex]\sqrt{5(4) - (-16)[/tex]

Solution = [tex]\sqrt{20+16}[/tex]

Solution = [tex]\sqrt{36}[/tex]

Taking square root of 36

Solution = 6

Thus,

[tex]\sqrt{5x^2-(-x^4)}[/tex] = 6

Hence,

The value of given expression is 6.
