An ellipse is defined as the locus of all points,the sum of whose from two given points is constant. Here z is a complex number whose distance from (1,0) and (−1,0) is constant. Hence the locus of z is an ellipse in the complex plane. Hence z will be all those points which lies on the ellipse with focus (−1,0) and (1,0).

Question 14

Jabar earns $5 for the first 10 pounds of newspaper he recycles, then $0.25 for each additional pound. Which expression represents the amount he earns for recycling p pounds of newspaper if p > 10?

a. 5+0.25 (p-10)

b. (5 +0.25) P

c. 5 +0.25p

d.5 (10) +0.25p

Answer:

5 (10) +0.25p

Step-by-step explanation:

Let the number of additional pounds = x

Hence:

Jabar earns $5 for the first 10 pounds of newspaper he recycles, then $0.25 for each additional pound.

The statement above is represented as:

$5 × 10 + $0.25 ×p

= 5(10) + 0.25(p)

Therefore, the expression that represents the amount he earns for recycling p pounds of newspaper if p > 10 is written as

5(10) + 0.25(p)

Option d is the correct option

Step-by-step explanation:

Okay so the sum of the angles inside this figure is

(6-2)*180=4*180=720

now, we can find 4 of the interior angles becuase they are supplementry.

180-54=126

180-51=129

There are two of each so we can just do 2(126)+2(129)=252+258=510

That means the two remaining angles that are supplementary to x equal to 510. they are equal, so we know the interior angles equal 720-510=210/2=105

Since the angles are supplementary, x=180-105=75

BTW: Supplementary angles are angles that equal to 180 degrees.

ABCD is a trapezium
Calculate the perimeter of the trapezium
Give your answer correct to 3 significant figures

Answers

Answer:

Perimeter = 101.496 cm

Step-by-step explanation:

draw line from point C that is perpendicular to line AD. Call that point E.

tan 43° = 16.7/ED

0.9325 = 16.7/ED

ED = 17.909 cm

sin 43° = 16.7/CD

0.6820 = 16.7/CD

CD = 24.487 cm

Perimeter = AB + BC + CD + ED + AE

Perimeter = 16.7 + 21.2 + 24.487 + 17.909 + 21.2 = 101.496 cm

The measures of the exterior angles of a pentagon are c, 2x, 4x, 5x, and 8x, solve for x

Answers

Answer:

X = 18

Step-by-step explanation:

x + 2x + 4x + 5x + 8x =360

20x = 360

20x/20= 360/20

x=18

The value of x in the pentagon angles is 3.6

What are pentagon?

Pentagon are polygons with five sides.

The exterior sides of the pentagon are given as follows:

x2x°4x°5x°8x°

Exterior angles formula for polygon is as follows:

exterior angle = 360 / n

where

n = number of sides

Therefore,

x + 2x + 4x + 5x + 8x = 360 / 5

x + 2x + 4x + 5x + 8x = 72

20x = 72

x = 72 / 20

x = 3.6

Number of yellow sweets = 5

Number of red sweets = 4

Number of green sweets = 8

Number of orange sweets = 4
