How do I find both answer for this question??
Paha777 [63]

Answer:

  (a)  46°

  (b)  86°

Step-by-step explanation:

When the secants cross externally (figure a), the angle where they cross is half the difference of the subtended arcs.

When they cross internally (figure b), the angle is half the sum of the subtended arcs.

__

<h3>(a)</h3>

Half the difference of arcs VW and VX is ...

  ∠VYW = 1/2(160° -68°) = 46°

  m∠VYW = 46°

__

<h3>(b)</h3>

Half the sum of arcs AB and CD is ...

  ∠CED = 1/2(arc AB +arc CD)

  2×∠CED = arc AB +arc CD . . . . . multiply by 2

  2×∠CED -arc AB = arc CD . . . . . subtract arc AB

  arc CD = 2×85° -84° = 86°

  m arc CD = 86°

Answer:

-1\frac{5}{2}-\frac{7}{12}=\frac{-49}{12}

Step-by-step explanation:

Given : Expression -1\frac{5}{2}-\frac{7}{12}

To find : Subtract the expression ?

Solution :

Step 1 - Write the expression,

-1\frac{5}{2}-\frac{7}{12}

Step 2 - Write mixed form into proper form,

-1\frac{5}{2}-\frac{7}{12}=-\frac{7}{2}-\frac{7}{12}

Step 3 - Take least common denominator,

-1\frac{5}{2}-\frac{7}{12}=\frac{-42-7}{12}

Step 4 - Solve,

-1\frac{5}{2}-\frac{7}{12}=\frac{-49}{12}

-1\frac{5}{2}-\frac{7}{12}=\frac{-49}{12}

A rectangular tank with a square​ base, an open​ top, and a volume of 10,976 ft cubed is to be constructed of sheet steel. Find
Marizza181 [45]

Answer:

Dimensions to minimize surface are is 28 ft x 28 ft x 14 ft

Step-by-step explanation:

The Volume of a box with a square base of say;x cm by x cm and height

h cm is;

V = x²h

Now, the amount of material used is directly proportional to the surface area, hence we will minimize the amount of material by minimizing the surface area.

The formula for the surface area of the box described is given by;

A = x² + 4xh

However, we need A as a function of

only x, so we'll use the formula;

V = x²h

V = x²h = 10,976 ft³

So,

h = 10976/x²

So,

A = x² + 4x(10976/x²)

A = x² + 43904/x

So, to minimize the area, it will be at dA/dx = 0.

So,

dA/dx = 2x - 43904/x² = 0

Factorizing out, we have;

2x³ = 43904

x³ = 43904/2

x³ = 21952

x = ∛21952

x = 28 ft

since, h = 10976/x²

h = 10976/28² = 14 ft

Thus,dimension to minimize surface are is 28 ft x 28 ft x 14 ft

Oh my life found out I have more homework help
Triss [41]

1. 8(-18d-10) = -144d-80

2. -13+14(-18+10d) = -13-252+140d = -265+140d

3. 15(-7x-3) = -105x-45

The number are quite weird but we have to deal with them.
