Answer:

[tex]W = 18[/tex] -- Width

[tex]H = 14[/tex] --- Height

Step-by-step explanation:

Given

[tex]V = 4284[/tex] -- Volume

[tex]L = 17[/tex] -- Length

[tex]H = ??[/tex] -- Height

[tex]W = 4 + H[/tex] -- Width

Required:

Find the height and the width

Volume is calculated as:

[tex]V = LWH[/tex]

This gives:

[tex]4284 = 17 * (4+H) * H[/tex]

[tex]4284 = 17 * (4H+H^2)[/tex]

Open bracket

[tex]4284 = 17 * 4H+17*H^2[/tex]

[tex]4284 = 68H+17H^2[/tex]

Divide through by 17

[tex]252 = 4H+H^2[/tex]

Write as a quadratic expression

[tex]H^2 + 4H - 252 = 0[/tex]

Expand

[tex]H^2 + 18H - 14H - 252 = 0[/tex]

Factorize:

[tex]H(H + 18) - 14(H + 18) = 0[/tex]

Factor out H + 18

[tex](H - 14)(H + 18) = 0[/tex]

[tex]H -14 = 0[/tex] or [tex]H + 18 = 0[/tex]

[tex]H = 14[/tex] or [tex]H = -18[/tex]

But Height can not be negative. So:

[tex]H = 14[/tex]

Recall that:

[tex]W = 4 + H[/tex]

[tex]W = 4 + 14[/tex]

[tex]W = 18[/tex]

Answer:

Step-by-step explanation:

You are given the equation g(x)=5x-2. You simply take the values given and put those values into the equation.

g(-4)=5(-4)-2=-20-2=-22

g(-7)=5(-7)-2=-35-2=-37

g(0)=5(0)-2=-2

g(23)=5(23)-2=115-2=113

g(38)=5(38)-2=190-2=188

Answer:

[tex]a= 2[/tex]

[tex]b = 3[/tex]

Step-by-step explanation:

Given

[tex]p(x,y) = (6,0)[/tex]

[tex]q(x,y) = (3,2)[/tex]

[tex]ax + by = 12[/tex]

Required

Find a and b

In [tex]p(x,y) = (6,0)[/tex], [tex]x = 6[/tex] and [tex]y = 0.[/tex]

This gives:

[tex]a*6 + b*0 = 12[/tex]

[tex]6a = 12[/tex]

Divide by 6

[tex]a= 2[/tex]

In [tex]q(x,y) = (3,2)[/tex]. [tex]x = 3[/tex] and [tex]y = 2.[/tex]

This gives:

[tex]a*3 + b*2 = 12[/tex]

[tex]3a + 2b = 12[/tex]

Substitute 2 for a

[tex]3*2 + 2b = 12[/tex]

[tex]6 + 2b = 12[/tex]

Collect Like Terms

[tex]2b = 12 - 6[/tex]

[tex]2b = 6[/tex]

Divide by 2

[tex]b = 3[/tex]

Answer:

3.86( rounded)

Step-by-step explanation:

========================================================

Explanation:

The ultimate goal is to find the value for lowercase c, or find the length of side c. So we'll use the portion sin(C)/c as part of the law of sines.

We don't know the value of lowercase 'a', so we'll ignore the sin(A)/a portion.

This leaves sin(B)/b

We see that one side is 2 cm long, so this means b = 2. The angle opposite this is 105 degrees, so B = 105.

The angle opposite side c is 15 degrees, so C = 15.

The lowercase letters represent side lengths, while the uppercase letters are angles.

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

We have enough to apply the law of sines to solve for side c.

sin(B)/b = sin(C)/c

sin(105)/2 = sin(15)/c

c*sin(105) = 2*sin(15) ............. cross multiply

c = 2*sin(15)/sin(105) .............. dividing both sides by sin(105)

c = 0.53589838486224

c = 0.5

Side c is roughly 0.5 cm long.

Make sure your calculator is in degree mode.

Answer:

  0.5 cm

Step-by-step explanation:

The Law of Sines tells you ...

  c/sin(C) = b/sin(B)

  c = b·sin(C)/sin(B)

  c = (2 cm)sin(15°)/sin(105°) ≈ (2 cm)(0.2588/0.9659) ≈ 0.5359 cm

  c ≈ 0.5 cm . . . . rounded to tenths

                                                                                                           -b

The axis of symmetry can be calculated using this formula:  x = ------

                                                                                                           2a

                                         -(-12)

which in this case is  x = ---------- = 1.  The axis of symmetry is the vertical

                                         2(6)             line x = +1

Thus, x = 1 is the x-coordinate of the vertex.  Normally we'd find the y-coordinate by evaluating the function at x = 1.  Unfortunately your

6x²-12x-25=-7 does not have the form of a quadratic function; such a function does not have the " = " sign in it.

Example:  Suppose we have  6x²-12x-25 = f(x) and we evaluate this function at x = 1:  f(1) = 6(1)^2 - 12(1) - 25 = -31, which (in this example)

leads to the vertex (1, -31).

Hello, I am BrotherEye

Answer:

Regression models are predictive tools. If you want to use them to predict the behavior of an individual, you must set "behavior" as your dependent variable, and you must have indicators and measures for such. You must also identify your explanatory or independent variable likewise you must have indicators and measures for such.

If you have built your model on the basis of collected data, you will be able to predict the value of behavior given a value of the explanatory variable.

Answer:

15/8 minutes

Step-by-step explanation:

The inverse relationship implies the following equation.

[tex]t=\frac{k}{T}[/tex]

where k is a constant.

You are given a t and T that go together, so

[tex]2=\frac{k}{75}[/tex]

This implies that k=150.  Now you know that the relationship is

[tex]t=\frac{150}{T}[/tex]

Now substitute 80 for T to get the answer.

[tex]t=\frac{150}{80}=\frac{15}{8}[/tex][tex]t=\frac{150}{80}=\frac{15}{8}[/tex]

  40 ft by 85 ft

Step-by-step explanation:

The total length of the three "vertical" partitions is ...

  3x = vertical partitions

The total length of the horizontal sides is ...

  2(x +(x +5)) = 4x +10

Then the perimeter is ...

  P = vertical partitions + horizontal sides

  290 = 3x +4x +10

  280 = 7x

  x = 40

  2x+5 = 85

The overall dimensions are 40 ft by 85 ft.
