504ft3

Step-by-step explanation:

V=Bh

V=(18x2) 14

V=36x14

V= 504

Answer:

volume = height × length ×width

volume =18×14×2

volume =504ft³

Answer:

$40

Step-by-step explanation:

f(x) = x³ - 2x² - 24x

x³ - 2x² - 24x = 0

x(x² - 2x - 24) = 0

x = 0

x² - 2x - 24 = 0

a = 1, b = -2, c = -24

Delta = (-2)² - 4 * 1 * (-24) = 4 + 96 = 100

x = (-(-2) - 10)/(2 * 1) = -8/2 = -4

x = (-(-2) + 10)/(2 * 1) = 12/2 = 6

Step-by-step explanation:

By utilizing trigonometric identities,we got cos 2θ = -1519/1681.

Given that sin θ = 40/41 and θ is a positive acute angle, we can find cos θ using the Pythagorean identity sin²θ + cos²θ = 1. Rearranging the equation, we have cos²θ = 1 - sin²θ.

Substituting the given value, we get cos²θ = 1 - (40/41)² = 1 - 1600/1681 = 81/1681.

Now, we can find cos 2θ using the double-angle identity cos 2θ = cos²θ - sin²θ.

Substituting the known values, we have

cos 2θ = (81/1681) - (40/41)² = 81/1681 - 1600/1681 = -1519/1681.

Therefore, cos 2θ = -1519/1681.

Answer:

The (x,y) point of the vertex is usually labelled as:

Vertex = (h, k)

h = -b / 2a

k = ah^2 + bh + c

f(x) = -3x^2 + 12x -5

a = -3 b=12 c=-5

h = -12 / -6  therefore h = 2

k = -3*2^2 + 12*2 -5

k = -12 + 24 -5  therefore k = 7

Answer:

  a.  see below for diagram. Angle for the length; length for the angle

  b. 6.84°; not to code

  c. 36.1 ft

Step-by-step explanation:

a. The diagram is shown below. Mr. Gow needs to find the angle it makes in order to determine if it is up to code. Alternatively, Mr. Gow needs to find the required length for a ramp that meets code.

__

b. The angle the ramp makes can be found using the tangent relation.

  Tan = Opposite/Adjacent

  tan(angle) = 3/25

  angle = arctan(3/25) ≈ 6.84°

The ramp will make a 6.84° angle with the ground. It will not meet code.

__

c. We can find the distance from the building where the ramp must start using the same trig relation.

  tan(4.75°) = (3 ft)/(distance)

  distance = (3 ft)/tan(4.75°) ≈ 36.1 ft

The ramp must start 36.1 feet from the building to exactly meet code.

Answer:

The regular cost of each ticket is $30

Step-by-step explanation:

Hi,

You and three friends means there was a total of 4 people. Your equation is...

4x - 20 = 100

Remember to add the -20 since there was a coupon that saved you $20.

Now solve...

4x - 20 = 100

+ 20 on both sides

4x = 120

Divide by 4 on both sides

x = 30

The regular cost of each ticket is $30

Hope this helps :)

The cost for each pound of trail mix is $1.5 and each pound of jelly beans is $3.5 .

The elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.

According to the question

A store is having a sale on trail mix and jelly beans .

Let trail mix = T

and  jelly beans = J

For 5 pounds of trail mix and 3 pounds of jelly beans, the total cost is $18.

i.e

5T + 3J = 18 -------------------------- (1)

For 2 pounds of trail mix and 12 pounds of jelly beans, the total cost is $45.  

i.e

2T + 12J = 45 -------------------------------(2)

Now,

multiplying eq (1) from 4

20T + 12J = 72 -----------------(3)

Solving equation (3) and (2) the equation by elimination method

20T + 12J = 72 -----------------(3)

2T + 12J = 45  -------------------------(2)

subtracting equation (2) from (3)

18T = 27

T = 1.5

substituting the value of T in equation 1

5T + 3J = 18

5*1.5 + 3J = 18

7.5 + 3J = 18

3J = 18 - 7.5

3J = 10.5

J = 3.5

Hence, the cost for each pound of trail mix is $1.5 and each pound of jelly beans is $3.5 .
