What is the coefficient of b² in the expression b²-b⁵+18?

$\blue{\textsf{\textbf{\underline{\underline{Answer:-}}}}$

$\blue{\textsf{\textbf{\underline{\underline{How to Solve:-}}}}$

The coefficient is defined as a number before a variable.

If there's no number, then the coefficient is 1.

Since b² has no number next to it, its coefficient is 1.

You are tired at the end of the term and decide to borrow $500 to go on a trip to Whatever Land. You go to the bank and borrow t

Andrej [43]

Answer:

$27.5

Step-by-step explanation:

P =$500, R = 11 pcpa, T = 6 months = 1/2 years

$I = \frac{PRT}{100} = \frac{500 \times 11 \times \frac{1}{2} }{100} \\ \\ = 5 \times 11 \times \frac{1}{2} \\ \\ = 55 \times \frac{1}{2} \\ \\ I= \$ 27.5$

Suppose a system of 2 linear equations has one solution. What must be true about the graph of the 2 equations

djverab [1.8K]

Answer:

They are intersecting lines.

Step-by-step explanation:

Parallel lines do not intersect and have no common solution. The same line has infinite solutions with itself. Anything else must be intersecting lines.

Mitchell took out a loan for $1100 at a 19.2% APR, compounded monthly, to

nevsk [136]

Answer:

The total number of the payments is 18 ⇒ answer A

Step-by-step explanation:

* Lets revise the rule of compounded monthly payment

→ $EMI=\frac{(A)(r)}{[1-\frac{1}{(1+r)^{n}}]}$ , where

- A is the loan amount

- r is monthly interest in decimal (R/12*100))

- n the total number of payments

∵ A = $1100

∵ EMI = $71.5

- Interest rate is 19.2% APR

∵ r = $\frac{19.2}{12*100}=0.016$

- Substitute these values in the rule to find n

∴ 71.5 = $\frac{1100(0.016)}{[1-\frac{1}{(1+0.016)^{n}}]}=\frac{17.6}{[1-\frac{1}{(1.016)^{n}}]}$

- By using cross multiplication

∴ 71.5[1 - $\frac{1}{(1.016)^{n}}$ ] = 17.6

- Divide both sides by 71.5

∴ 1 - $\frac{1}{(1.016)^{n}}$ = $\frac{16}{65}$

- Subtract 1 from both sides

∴ - $\frac{1}{(1.016)^{n}}$ = - $\frac{49}{65}$

- Multiply both sides by -1

∴ $\frac{1}{(1.016)^{n}}$ = $\frac{49}{65}$

- By using cross multiplication

∴ 49[ $(1.016)^{n}$ ] = 65

- Divide both sides by 49

∴ $(1.016)^{n}$ = $\frac{65}{49}$

- Insert log for both sides

∴ ㏒ $(1.016)^{n}$ = log( $\frac{65}{49}$ )

- Put n in-front of the ㏒

∴ n㏒(1.016) = ㏒( $\frac{65}{49}$ )

- Divide both sides by ㏒(1.016)

∴ n = 17.8 ≅ 18

* <em>The total number of the payments is 18</em>

un objeto cae accidentalmente de un vehículo que lleva una rapidez de 50 kilómetros por hora y recorre 20 m antes de detenerse

Svet_ta [14]

Un objeto cae accidentalmente de un vehículo con una velocidad de

50 km / hy recorra 20 m antes de detenerse.

Calcular:

a) La aceleración:

b) El tiempo que tarda en detenerse:

Responder:

1.439 s

-9,645 m / s²

Explicación paso a paso:

Dado que:

Velocidad en m / s = (50 * 1000) / 3600 = 13.899 m / s

Distancia (d) = 20

Tiempo = distancia / velocidad

Tiempo = 20 / 13.889

Tiempo = 1.439 s

Aceleración (a):

Cambio de velocidad / tiempo empleado

= (0 - 13,889) / 1,439

- 13.889 / 1.439

= -9,645 m / s²
