What is the real- world meaning of the first equation?

The first equation is: 2x+3y=13.50

[tex]\rule{300pt}{1pt}[/tex]

Solve this system of equations using the substitution method.

[tex] 2x + 3y = 13.50 \\ 3x + 2y = 16.50[/tex]

[tex]2x + 3y = 13.50 \\ x = 5.5 - \frac{2}{3} y[/tex]

[tex]2(5.5 - \frac{2}{3} y) + 3y = 13.50[/tex]

[tex]y = 1.5[/tex]

[tex]x = 5.5 - \frac{2}{3} \times 1.5[/tex]

[tex]x = 4.5[/tex]

[tex](x,y)=(4.5,1.5)[/tex]

Veremos que la velocidad un minuto despues es 1,200 m/s.

Sabemos que la aceleración del cohete es constante, y es de 20 m/seg^2 (asumimos que el cohete tiene esta aceleración teniendo en cuenta la aceleración gravitatoria, es decir, 20m/seg^2 es la aceleración neta).

a(t) = 20m/seg^2.

Para obtener la velocidad, integramos la cantidad de arriba:

v(t) = (20 m/seg^2)*t + V

Donde V es la velocidad inicial del cohete, que sabemos es igual a cero.

v(t) = (20 m/seg^2)*t.

Con esta ecuación, podemos ver que la velocidad un minuto despues será:

v(60s) = (20 m/seg^2)*60s = 1,200 m/s.

Answer:

Each student must raise $14.90

Step-by-step explanation:

This is actually fairly easy to figure out (at least this part) all you do is 447/30 and then you get your 14.9 (14.90)

m = 14.90

30m = 447

Roots Theorem

[tex]6 {x}^{2} + 11x - 10 = 0[/tex]

Use the AC method,

The roots must multiply to -60 and add up to 11.

Those two numbers are 15 and -4

So we have know

[tex]6 {x}^{2} + 15x - 4x - 10 = 0[/tex]

[tex]3x(2x + 5) - 2(2x + 5)[/tex]

[tex](3x - 2)(2x + 5) = 0[/tex]

Set each binomial equal to zero

[tex]3x - 2 = 0[/tex]

[tex]3x = 2[/tex]

[tex]x = \frac{2}{3} [/tex]

[tex]2x + 5 = 0[/tex]

[tex]2x = - 5[/tex]

[tex]x = - \frac{5}{2} [/tex]

Answer: Length - 40 cm, Width - 6cm

Step-by-step explanation:

Let the length of the rectangle = 20x.

Then, the width of the rectangle must = 3x by the ratio given.

The area of a rectangle is the length*width, which we are given as 240.

Therefore, 20x*3x = 240

We can combine like terms:

60x^2 = 240

Divide both sides by 60:

x^2 = 4

Square root both sides:

x = ± 2.

Since the sides of a rectangle cannot be negative, x must equal to 2.

The length of the rectangle is 20x, which is 20*2 = 40.

The width of the rectangle is 3x, which is 3*2 = 6.

[tex]\sf 1 \ hour \rightarrow \dfrac{4}{5} \ or \ 0.8 \ of \ her \ game[/tex]

Solution:

We know that:

Let's multiply 4 both sides to see how much Sophia can code in 1 hour.

Multiplying 4 both sides:

Finding how much Sophia can code in 1 hour.

Thus, Sophia can code 4/5 of her game in 1 hour.

Answer:

I believe answer would be B

Step-by-step explanation:

I put the equation into desmos and B looks like the answer.

The graph of the polar curve r = 1 + sinФ is shown.

A form created using the polar coordinate system is called a polar curve. Points on polar curves have varying distances from the origin (the pole), depending on the angle taken off the positive x-axis to calculate distance.

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
r = 1 + sin(θ)
Using formula ,
r = a±bsinФ

Where,
a > 0 and b >0
and a = b
graph the cardioid.
r = 1 - sinФ

Thus, the graph of the polar curve r = 1 + sinФ is shown.

Step-by-step explanation:

The immediate effect on the money supply when the Federal Reserve sells $50,000 in Treasury bonds to a bank at 8% interest is that It is decreased by $50,000.

Option A is the correct answer.

We have,

When the Federal Reserve sells Treasury bonds to a bank, it takes money out of the banking system.

The concept used in this scenario is the Open Market Operations (OMO) conducted by the central bank, which in this case is the Federal Reserve.

Open Market Operations refer to the buying and selling of government securities, such as Treasury bonds, by the central bank in the open market.

The bank pays $50,000 to the Federal Reserve to purchase the bonds, and this money is removed from the money supply, leading to a decrease in the overall money supply in the economy.

Thus,

The immediate effect on the money supply is:

A. It is decreased by $50,000.

Answer:

-17 (I believe)

Step-by-step explanation:

If x = 64 then the first one is asking for the square root of 64 (8)

With y being 25 the second part of this problem is actually really easy, all its doing is getting the square root and then squaring it (doing nothing at all) so that would just be 25 which would make it

Answer:

tan²Θ

Step-by-step explanation:

simplify the expression using the identities

secΘ = [tex]\frac{1}{cos0}[/tex]

tan²Θ = sec²Θ - 1

then

[tex]\frac{cos0-cos^30}{cos^30}[/tex] ( divide each term on the numerator by cos³Θ

= [tex]\frac{cos0}{cos^30}[/tex] - [tex]\frac{cos^30}{cos^30}[/tex]

= [tex]\frac{1}{cos^20}[/tex] - 1

= sec²Θ - 1
