Mathematics
1 answer:
Kryger [21]3 years ago

Answer:

x = \frac{3}{2}

Step-by-step explanation:

Given 2 intersecting chords, then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

18x = 9 × 3 = 27 ( divide both sides by 18 )

x = \frac{27}{18} = \frac{3}{2}

Answer:

c = \frac{b^2-R^2}{4a}

Step-by-step explanation:

Given

R= \sqrt{b^2-4ac}

Clear the radical by squaring both sides

R² = b² - 4ac ( subtract b² from both sides )

R² - b² = - 4ac ( multiply all terms by - 1 )

b² - R² = 4ac ( divide both sides by 4a )

\frac{b^2-R^2}{4a} = c

B) The finance charge is the total of payments less the amount financed.
  18*$121.00 -2000.00 = $178.00

Determine whether a triangle can be formed with the given side lengths. If so, use Heron's formula to find the area of the trian
mart [117]

Answer:

The area is 11317.51

Step-by-step explanation:

The sum of 2 sides must be less than the third side (largest side) for a triangle to be formed.

b+c<a

133+174 < 240

A triangle can be formed

To use Herons formula for the area

We find S = 1/2( a+b+c)

                 = 1/2(240+133+174)

                 =  1/2 (547)

                     = 273.5


Area = sqrt( S (S-a) (S-b)(S-c))

           sqrt((273.5 ) (273.5 -240) (273.5-133) (273.5-174))

           sqrt((273.5)(33.5) (140.5) (99.5))

            sqrt(128085964.4)

           11317.50699

The area is 11317.51

What is the area of the trapezoid? The diagram is not drawn to scale.
Katyanochek1 [597]

Answer:

The area of trapezoid is 72 cm²

Step-by-step explanation:

Given : A trapezoid with given dimensions.

We have to find the area of trapezoid ABCD.

Consider the given trapezoid ABCD ,

AB = EF = 8 cm

and CE = FD = 4 cm

Then CD = CE + EF + FD = 4 + 8 + 4 = 16 cm

Thus, Area of trapezoid = \frac{1}{2}\cdot \text{(Sum of parallel sides)} \cdot height

here, height = 6 cm

and sum of parallel sides = AB + CD = 16 + 8 = 24 cm

Thus,  Area of trapezoid = \frac{1}{2}\cdot 24 \cdot 6

Simplify, we have,

Area of trapezoid = 72 cm²

Thus, The area of trapezoid is 72 cm²
