Answer:

dis is easy c :D

Step-by-step explanation:

Answer:

(h) y =  -8/3·x + 16·a/3

(i) dt = √(x² + y²) = √( (a + 3·t)² + (b + 8·t)²)

(j)  [tex]\dfrac{d(t)}{dt} = \dfrac{3\cdot a +8\cdot b+ 73 \cdot t}{\sqrt{a^2 + 6\cdot a \cdot t + b^2+16 \cdot b \cdot t + 73\cdot t} }[/tex]

Step-by-step explanation:

(h) The location of the object = P(t) = (x(t), y(t))

Where;

x(t) = a + 3·t

y(t) = b + 8·t

Therefore we have;

At x = 0, t = -a/3. at y = 0, b = -8·t = -8·a/3

y = -8·a/3 + 8·t = -8/3(a - 3·t) = -8/3(x - 2·a) = -8/3·x + 16·a/3

y =  -8/3·x + 16·a/3

(i) dt = √(x² + y²) = √( (a + 3·t)² + (b + 8·t)²)

(j) The instantaneous rate of change of d(t), with a corresponding change in time, t, obtained by solving through an online platform, is given as follows;

[tex]\dfrac{d(t)}{dt} = \dfrac{d}{dt} \left (\sqrt{\left (a + 3\cdot t \right)^2 + \left (b + 8\cdot t \right)^2} \right ) = \dfrac{3\cdot a +8\cdot b+ 73 \cdot t}{\sqrt{a^2 + 6\cdot a \cdot t + b^2+16 \cdot b \cdot t + 73\cdot t} }[/tex].

Answer:

4) t -3

Step-by-step explanation:

-16t² = -16 * t * t

48t = (-16t) * (-3)

-16t² + 48t = (-16t) * t + (-16t) *(-3)

                = (-16t) [ t - 3]

Answer:

Step-by-step explanation:

Isolate 8y.

7x + 8y - 16 = 0

       -8y         -8y

Divide by -8.

7x - 16 = -8y

/-8  /-8    /-8

-7/8x + 2 = y

y = -7/8x + 2

Answer:

Answer:

4.5 miles

Step-by-step explanation:

Given

[tex]Middle\ School = (15,13)[/tex]

[tex]Library = (27,9)[/tex]

To solve this, we simply solve for the distance (D) between both points.

[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Where:

[tex](x_1,y_1) = (15,13)[/tex]

[tex](x_2,y_2) = (27,9)[/tex]

[tex]D = \sqrt{(27 - 25)^2 + (9 - 13)^2}[/tex]

[tex]D = \sqrt{(2)^2 + (-4)^2}[/tex]

[tex]D = \sqrt{4 + 16}[/tex]

[tex]D = \sqrt{20}[/tex]

[tex]D=4.472135955[/tex]

[tex]D=4.5[/tex] --- approximated

Since each unit is 1 mile. The distance is 4.5 miles

Answer:

Any negative number would be a counterexample.

Step-by-step explanation:

Since negative numbers get smaller as you multiply them by a larger number, this would prove this conjecture false.

Answer:

Step-by-step explanation:

Given the -4(-9 + x) = 57, to solve this equation, follow the following steps:

Expend the parentheses at the left hand side using the distributive law.

-4(-9)+(-4x) = 57

Open the bracket by multiplying

+36-4x= 57

Subtract 36 from both sides

36-4x-36 = 57-36

-4x = 21

Divide both sides by -4

-4x/-4 = 21/-4

x = -21/4

From the calculation, we can see that we used 3 operations (multiplication, subtraction and division operations)

The most preferred is multiplication operation because the operation helps to simplify the parentheses using the distributive law in step 1.

Answer:

La cantidad de boletos vendidos en la sección numerada = x = 4000 boletos

El número de entradas vendidas en la sección general = y = 8000 boletos

Step-by-step explanation:

Deje que el número de boletos vendidos en la sección numerada = x

Sea el número de boletos vendidos en la sección general = y

Es un partido de fútbol sala se vendieron 12.000 entradas.

x + y = 12000.… ..... Ecuación 1

x = 12000 - y

El precio de las entradas es de $ 25.00 en la sección numerada y $ 15.00 en la general. Si el ingreso total obtenido fue de $ 220,000.00,

$ 25 × x + $ 15 × y = $ 220 000

25x + 15y = 220.000 ..... Ecuación 2

Sustituya x por 12000 - y en la ecuación 2

25 (12 000 - años) + 15 años = 220 000

300000 - 25 años + 15 años = 220 000

300000 - 220000 = 25 años - 15 años

80000 = 10 años

y = 80000/10

y = 8000 boletos

x = 12000 - y

x = 12000 - 8000

x = 4000 boletos

La cantidad de boletos vendidos en la sección numerada = x = 4000 boletos

El número de entradas vendidas en la sección general = y = 8000 boletos

Responder:

8000

Explicación paso a paso:

Dado que las entradas:

Sección numerada = $ 25

Sección general = $ 15

Ingreso tital = 220.000

Número de entradas vendidas = 12000

Deje el boleto vendido de la sección numerada = n

Número vendido de la sección General = g

n + g = 12000

25n + 15g = 220.000

n = 12000 - g

25 (12000 g) + 15 g = 220000

300.000 - 25g + 15g = 220000

-10g = 220000 - 300000

-10g = - 80000

g = 8000

n = 12000 - g

n = 12000 - 8000

n = 4000

Entradas vendidas de la sección General = 8000

Answer:

The correct choice is D.

Answer:

T = 5.79 (approximated)

Step-by-step explanation:

Using I = PRT/100

where P = The principal amount invested = $5500

R = Rate of Interest =5%

T = Time (in years)

I = Interest = $7,739.05 - $5500 = $2239.05

Substituting the above values in the formula

I = PRT/100 becomes

2239.05 = 7,739.05 * 5 * t / 100 -------- Multiply 100 to both sides

2239.05 * 100 = 100 * 7739.05 * 5 * t / 100

223905 = 7739.05 * 5 * t

223905 = 38695.25t

Divide both sides by 38695.25t

223905/38695.25 = t

5.786369 = t

T = 5.79 (approximated)

Answer:

Base Fee = $7

Extra charges = $7

Step-by-step explanation:

Represent the base charge with x and the additiional charges with y.

For the 5 hours job, we have:

[tex]42 = x + 5y[/tex]

For the 3 hour job

[tex]28 = x + 3y[/tex]

Solving for x and y;

[tex]42 = x + 5y[/tex]

[tex]28 = x + 3y[/tex]

Subtract the second equation from the first

[tex]42 - 28 = x - x + 5y - 3y[/tex]

[tex]14 = 2y[/tex]

Solve for y

[tex]y = 14/2[/tex]

[tex]y = 7[/tex]

Substitute 7 for y n the first equation

[tex]42 = x + 5y[/tex]

[tex]42 = x + 5 * 7[/tex]

[tex]42 = x + 35[/tex]

[tex]x = 42 - 35[/tex]

[tex]x = 7[/tex]

Answer:

6

Step-by-step explanation:

11 - -5 = 6

The temperature at noon is 6 degrees Celsius.

Suppose it was -5 degrees Celsius at 6:00 a.m.

By noon, the temperature had increased by 11 degrees.

Temperature declines as altitude increases.

The temperature at noon is calculated by adding the morning temperature and temperature in the afternoon.

The temperature in noon = temperature at 6;00 a.m. + increase in temperature in afternoon.

The temperature in noon = -5 + 11

The temperature in noon = 6 degrees.

Hence, the temperature at noon is 6 degrees Celsius.

Answer:

20%

Step-by-step explanation:

First we find the actual dollar amount of the discount.

$65.50 - $52.40 = $13.10

Now we need to find what percent of $65.50 is $13.10.

To find what percent a part is of the whole, divide the part by the whole and multiply by 100%.

percent = part/whole * 100%

percent = $13.10/$65.50 * 100% = 20%
