Answer:

so i'm guessing since 5 times 5 is 25 but there is a 2 on top of the number 25 that means squared meaning your're going to multiply. can i get a thanks and a rate!

In a small town in the Himalayas, the average snowfall each month is 6 inches. July is the month with the lowest average snowfal

OLga [1]

The function that models the above behavior is given as:

f(x) = ACos(B(x + C)) + 6 ..... .......i

where x = 1 (that is January)

D (Average Snowfall) = 6.

Hence, the amplitude (A) is given as:
A = 6-1

= 5

<h3>What is a mathematical function?</h3>

A mathematical function is a function comprising of different variables that represent different factors or events and the relationships between them.

<h3>
During what period is there more than 10 inches of snowfall?</h3><h3 />

Recall that in a year we have 12 months. Hence, P = 12

→ P = (2π) /.B → (2π)/B = 12 → B = π/6

Taking the values of A and B and plugging them in, we ahve:

F(x) = 5 cos (π/6(x + C)) + 6................ii

This means that in July, we'll have

x = 7 and f(x) = 1

Therefore,

1 = 5cos ((π/6) (7 + C) + 6 → 5 Cos ((π/6) (7 + C) → -5cos ((π/6) (7 + C)

= -1

→ ((π/6) (7 + C) = π

→ 7 + C = 6

→ C = -1

Taking equation ii, we have

F(x) = 5cos ((π6) (x -1)) + 6

F (x) > 10

Therefore

5cos ((π/6) (x-1) + 6 > 10

→ cos ((π/6) (x-1) + 6 > 4/5

→ (π/6) (x-1) > Cos⁻¹ (4/5)

(π/6) (x-1) < 0.6435 and

(π/6) (x-1) > 5.6397

→ x < 2.23 and x > 11.77

The interpretation is that upwards of ten inches of snow fall in January, February, November, and December.

Which expression is equivalent to 3 7/8-6 1/4

Serhud [2]

get a common denominator which is 24

3 7/8 = 3 21/24

6 /4 = 6 6 /24

3 21/24 - 6 6 /24

big number minus small number take sign of larger

6 6/24

- 3 21/24

-------------

5 30/24

3 21/24

--------------

2 9/24

2 3/8

the sign of the larger is negative

-2 3/8

Given A(2,14), B(2,3), C(4,2) and D(14,2) what about AB?

stepan [7]

Answer - 11

I’m assuming you’re trying to find the line AB (basically the distance between point A and B). If that’s the case, since they both have the same x vale, subtract their y values. 14-3 gives you 11, which is the length of line AB

Acertijo.

Cerrena [4.2K]

La edad de cada uno de los integrantes del acertijo es:

Luisa = 3 años 
Juan = 6 años 
Carmen = 8 años

Cálculo por medio de ecuaciones y el método de igualación.

Haciendo uso de la información brindada en el ejercicio, se procede a formular variables con las cuales se calcularán las ecuaciones, por lo tanto:

X = Edad de Luisa
Y = Edad de Juan
Z = Edad de Carmen

Con el enunciado: "Luisa es 3 años más joven que su hermano Juan" se crea la primera ecuación:

1. Y = X + 3

Con el enunciado: "Su hermana Carmen es 2 años mayor que Juan", se crea la segunda ecuación:

2. Z = Y + 2

Y con el enunciado: "Juan tiene el doble de edad que Luisa", se crea la tercera ecuación:

3. X = $\frac{Y}{2}$

Ahora, utilizando el método de igualación, se reemplaza la tercera ecuación en la primera:

Y = X + 3
Y = ( $\frac{Y}{2}$ ) + 3

Y se procede a sumar:

Y = ( $\frac{Y}{2}$ ) + 3
Y = $\frac{Y+6}{2}$

El dividendo se pasa al otro lado de la igualdad a multiplicar:

2Y = Y + 6

Y la variable "Y" que está sumando, se pasa al otro lado de la igualdad a restar:

2Y - Y = 6
Y = 6

Con el valor de Y (edad de Juan) se calcula X con la tercera ecuación:

X = $\frac{Y}{2}$
X = $\frac{6}{2}$
X = 3

Una vez calculado el valor de X (edad de Luisa), se procede a calcular el valor de Z con la segunda ecuación:

Z = Y + 2
Z = 6 + 2
Z = 8

Por lo tanto, se calcula que la edad de Luisa es 3 años, la edad de Juan es 6 años y la edad de Carmen es 8 años.

Find the surface area of composite figure. Please help

Ivan

Answer:

The surface area of the composite figure is $410\ m^{2}$

Step-by-step explanation:

we know that

The surface area of the composite figure is equal to the surface area of the rectangular prism of the bottom plus the lateral area o the rectangular prism of the top

Step 1

Find the surface area of the rectangular prism of the bottom

The surface area is equal to

$SA=2B+Ph$
