find 3 numbers in GP whose sum is 28 and product is 512​

Answers

Answer 1

Answer:

4,8 and 16

Let the three numbers be a,ar, ar^2 ,

where r is the common ratio.

⇒a+ar+ar^2 =28 and a^3 r^3 =512

⇒ar=8⇒a+ar^2 =20

⇒8r^2 −20r+8=0

⇒r=2,r= 1/2

If r=2,a=4

Therefore, the three numbers are 4,8,16.

Solve for x.
A = (5x+14)°
B = (3x +8)°

Answers

Answer:

x = 15

m∡A = 89°

m∡B = 53°

Step-by-step explanation:

this shape is a kite and opposite angles (where sides of different lengths meet) are congruent

so ∡B = ∡D

109 + 109 + 5x + 14 + 3x + 8 = 360

218 + 8x + 22 = 360

8x = 120

x = 15

m∡A = 5(15) + 14 = 89°

m∡C = 3(15) + 8 = 53°

Answer:

B and C

Step-by-step explanation:

Not A because the side lengths aren't multiples.

Not D because it would be congruent, unless it had different angles, but then similar shaps must have the same angles

Find the area of the shaded region. Round to the nearest hundredth when necessary.

Answers

Answer:

Area of the shaded region is 223.72 square units.

Step-by-step explanation:

Area of the shaded region = Area of parallelogram - Area of triangle

Area of the parallelogram = base x height

                                      = 23.8 x 15

                                      = 357 square feet

Area of triangle = [tex]\frac{1}{2}[/tex] x base x height

Let the height of the triangle be represented by h, applying the Pythagoras theorem;

[tex]23.8^{2}[/tex] = [tex]21^{2}[/tex] + [tex]h^{2}[/tex]

566.44 = 441 + [tex]h^{2}[/tex]

[tex]h^{2}[/tex] = 125.44

h = [tex]\sqrt{125.44}[/tex]

   = 11.2

h = 11.2

Area of the triangle = [tex]\frac{1}{2}[/tex] x 23.8 x 11.2

                              = 133.28

Area of shaded region = 357 - 133.28

                                      = 223.72

Area of the shaded region is 223.72 square units.

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

Answer:

y/-3 = 1/6

y = 1/6 × 3

y = 0.5

Answer:

-1/2 and -0.5

Explanation :

Hey! Ok so you will plug in all the value in the y to find out if it equals to 1/6.

y ÷ -3 = 1/6

0.5 ÷ -3 = 1/6

-1/6 = 1/6 ---> NO

y ÷ -3 = 1/6

-1/2 ÷ -3 = 1/6

1/6 = 1/6 ---> YES

y ÷ -3 = 1/6

-0.5 ÷ -3 = 1/6

1/6 = 1/6 ---> YES

y ÷ -3 = 1/6

-18 ÷ -3 = 1/6

6 = 1/6 ---> NO
