Answer:

x = -9

Step-by-step explanation:

5x + 4 = -41 Your goal is to get x alone on on side

- 4 - 4 Subtract 4 from both sides to get 5x alone

5x = -45 Now you need to divide to get what x equals

$\frac{5x}{5} = \frac{-45}{5}$ Divide by 5 to get x

$x = -9$

Troy took out an 80/20 mortgage to buy a house costing $100,000. The first (80%) mortgage has an interest rate of 4.75%, The sec

tekilochka [14]

Answer:

$557.51

Step-by-step explanation:

A financial calculator tells you the payments are ...

on $80,000 at 4.75%: $417.32

on $20,000 at 7.525%: $140.19

Then the total monthly payment is ...

$417.32 +140.19 = $557.51

_____

You can use the amortization formula to find the payment (A) on principal P at interest rate r for t years to be ...

A = P(r/12)/(1 -(1+r/12)^(-12t))

I find it takes fewer keystrokes to enter the numbers into a financial calculator. Both give the same result.

What is the reactance of a 25 mF capacitor when the applied frequency is 400 Hz?

LuckyWell [14K]

The Reactance of a Capacitor is t<u>he resistance it has when alternating current (A/C) with a specific frequency (f) passes through it. </u>This is measured in ohms (Ω) and its formula is:

$X_{C}=\frac{1}{2\pi fC}$ (1)

Where:

$X_{C}$ is the Reactance in ohms (Ω)

$f$ is the frequency of the alternating current in Hertz ( $Hz$ )

$C$ is the Capacitance of the Capacitor in Farad ( $F$ )

In this case we have a 25 mF capacitor with an applied frequency of 400 Hz.

Note $1mF=1*10^{-3}F=0.001F$

Well, with the given data we have to solve (1):

$X_{C}=\frac{1}{2\pi(400Hz)(25*10^{-3}F)}$

Then:

XC=0.0159 Ω This is the Reactance of the Capacitor

Use synthetic division to find P (-10) for P(x)=2x^3+14x^2-58x

Savatey [412]

The polynomial remainder theorem states that the remainder upon dividing a polynomial $p(x)$ by $x-c$ is the same as the value of $p(c)$ , so to find $p(-10)$ you need to find the remainder upon dividing

$\dfrac{2x^3+14x^2-58x}{x+10}$

You have

..... | 2 ... 14 ... -58
-10 | ... -20 ... 60
--------------------------
..... | 2 ... -6 .... 2

So the quotient and remainder upon dividing is

$\dfrac{2x^3+14x^2-58x}{x+10}=2x-6+\dfrac2{x+10}$

with a remainder of 2, which means $p(-10)=2$ .

A new bank costumer with 2500 dollars wants to open a money market account. The bank is offering a simple interest rate of 1.5 p

padilas [110]

Answer:

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the amount deposited.

P represents the principal or amount deposited.

R represents interest rate

T represents the duration in years.

From the information given,

P = 2500

R = 1.5%

T = 30 years

I = (2500 × 1.5 × 30)/100 = $1125

the account balance be after 30 years is

1125 + 2500 = $3625
