Step-by-step explanation:

9514 1404 393

Answer:

  1173 in

Step-by-step explanation:

The measure of angle O is ...

  O = 180° -N -P = 180° -32° -97° = 51°

The law of sines tells you ...

  o/sin(O) = n/sin(N)

  o = n·sin(O)/sin(N) = (800 in)·sin(51°)/sin(32°)

  o ≈ 1173 in

Step-by-step explanation:

sin=opposite/hypotenuse

Sinx=40/41

Step-by-step explanation:

Answer:

A = 4 pi R^2     V = 4/3 pi R^3

A / V = 3 / R

Also, R = (3 * V / 4 * pi)^1/3 = (3 * 904.32 / (4 * pi))^1/3 = 6 in

So A = 3 / 6 * V = 1/2 * 904.32 = 452.16 in^2

The surface area of the sphere is S = 452.39 inches²

A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.

The Surface Area of a Sphere = 4πr²

The Volume of a Sphere = ( 4/3 ) πr³

where r is the radius of the sphere

Given data ,

Let the volume of the sphere be V = 904.32 inches³

Let the surface area of the sphere be S

And , Volume of a Sphere = ( 4/3 ) πr³

In this case, we are given that the volume of the sphere is 904.32 cubic inches, so we can set up an equation:

904.32 = (4/3)πr³

Solving for r:

r³ = (3/4) x (904.32 / π)

r ≈ 6.0 inches (rounded to one decimal place)

Now that we know the radius, we can use the formula for the surface area of a sphere:

A = 4πr²

Plugging in the value of r:

A = 4 x 3.14 x 6.0²

A ≈ 452.39 inches² (rounded to two decimal places)

Hence , the surface area of the sphere is approximately 452.39 square inches.

Answer:

[tex]-\frac{106}{5} or -21.2[/tex]

Step-by-step explanation:

First we would have to get x and y-values by solving systems of equations:

isolate one of the variable from any of the first 2 equations given:

-2x+ y =6 would be y = 2x + 6 when y is isolated.

now plug this equation in for the y given in the second equation:

-7x -4(2x + 6) = -8

Now solve to get the x-value,

-7x - 8x - 24 = -8

-15x - 24 = -8

-15x = 16

x = [tex]-\frac{16}{15}[/tex] or -1.06

To solve for y-value, substitute the gotten x-value in any of the 2 equations and solve:

y = 2([tex]-\frac{16}{15}[/tex]) + 6

y = [tex]\frac{58}{15}[/tex] or 3.86

Now that we have the x and y-values, substitute them in for the 3 equation given:

-9([tex]-\frac{16}{15}[/tex]) -3( [tex]\frac{58}{15}[/tex])

=> [tex]-\frac{106}{5}[/tex] or -21.2 = Final Answer

Answer:

The first term is -3.

Step-by-step explanation:

Arithmetic sequence:

In an arithmetic sequence, the difference between two consecutive terms is always the same, and it is called common difference d.

The nth term is given by:

[tex]a_n = a_1 + (n-1)d[/tex]

In which [tex]a_1[/tex] is the first term.

If we have the mth term instead of the first, we have:

[tex]a_n = a_m + (n-m)d[/tex]

We have the third term, and need the fifth and the sixth:

So we write both the fifth and the sixth in function of the third, then:

[tex]a_5 = a_3 + 2d = 5 + 2d[/tex]

[tex]a_6 = a_3 + 3d = 5 + 3d[/tex]

The sum of the fifth and sixth term of an AP is 30

We use this to find [tex]d[/tex]. So

[tex]a_5 + a_6 = 30[/tex]

[tex]5 + 2d + 5 + 3d = 30[/tex]

[tex]5d + 10 = 30[/tex]

[tex]5d = 20[/tex]

[tex]d = \frac{20}{5} = 4[/tex]

First term:

The third term is:

[tex]a_3 = a_1 + 2d[/tex]

Since [tex]a_3 = 5, d = 4[/tex]

[tex]a_1 = a_3 - 2d = 5 - 8 = -3[/tex]

The first term is -3.
