Answer:

B - 593.8 ft2

Step-by-step explanation:

I also just finish the quiz and got the question right.

To find the base: 10 x 18 = 180

There are 4 lateral face, two each are conguent:

18 x 14.1 = 253.8

253.8 divided by 2 = 126.9

126.9 x 2 = 253.8

Other conguent sides:

10 x 16 = 160

160 divided by 2 = 80

80 x 2 = 160

Finally: 180 + 253.8 + 160 = 593.8 ft2

If the angles<br> are represented in degrees, find both angles:<br> sin(x + 7) = cos(4x + 8)
ValentinkaMS [17]

Answer:

x = -1/3

Step-by-step explanation:

We have,

sin(x + 7) = cos(4x + 8)

We need to find the value of x.

We know that,

sin(90-x) = cosx

So,

sin(90-(x + 7)) = cos(4x + 8)

cos(x+7) = cos(4x + 8)

i.e.

(X+7) = (4x+8)

7-8 = 4x-x

-1 = 3x

x = -1/3

The expression 1.08s + 1.02b1.08s+1.02b predicts the end-of-year value of a financial portfolio where ss is the value of stocks
Marysya12 [62]

Answer:

$22350 is the predicted value of portfolio.

Step-by-step explanation:

The given expression is 1.08s + 1.02b1.08s + 1.02b which predicts the end of year value of a financial portfolio.Here s = value of stocks and b = value of bonds.

Now we have to calculate the value of a portfolio with s = $200 and b = $100

So we will put the values of s and b in the given expression to calculate the value portfolio.

1.08×200 +1.02×(100)×1.08×(200)+ 1.02×(100) = 216 + 22032 + 102

= $22350

The predicted end to end year value of portfolio is = $22350

el operador de un elevador registro el numero de pisos que este subio y bajo en varias ocasiones para llegar de la planta baja h
balandron [24]

Responder:

Por favor, consulte la explicación.

Explicación paso a paso:

Dado que :

Número total de movimientos realizados:

5 (2 movimientos hacia abajo y 3 movimientos hacia arriba) para llegar al noveno piso desde la planta baja.

Tome el movimiento hacia abajo como (-)

Movimiento ascendente como (+)

Número de pisos entre la planta baja (0) y el 9 ° piso: (9-0) = 9

Usando el operador de multiplicación, podemos obtener el número de pisos movidos hacia arriba y hacia abajo antes de llegar al noveno piso.

9 * 3 = 27 pisos (hacia arriba)

9 * 2 = 18 pisos (hacia abajo)

Cheque:

27 - 18 = 9
