The diagonals of a kite are 21cm and 11cm. Find the perimeter of the kite.

Answers

Answer:

Perimeter: 64 cm

Step-by-step explanation:

21 + 21 = 42 cm 11 + 11 = 22 cm

42 + 22 = 64 cm

Answer: 64 cm

Step-by-step explanation:

You get the value of the perimeter by adding up all the four sides of the kite. Kites typically have 4 sides, and 2 equal sides, this means that there are two sides of the kite which are 21 cm long, and 2 sides that are 11 cm long. This represented as an expression would be 21+21+11+11, which would simply equal to 64 cm

Given the parallelogram ABCD ;

side AB is always Parallel to CD, hence ;

AB = CD = 7.2cm

Perpendicular from C on AB is the height of the parallelogram = 4.5cm

Area of a parallelogram : base * height

Area of a parallelogram = length base * height

Area of a parallelogram = 7.2 cm * 4.5cm

Area of parallelogram = 32.40cm²

Tara is graphing the equation 4x + 2y = 10. Which of these shows the correct equation in slope-intercept form, slope, and y-intercept?

Question 2 options:

y = –2x + 5

slope = –2

y-intercept = 5


y = 2x + 4

slope = 2

y-intercept = 4


y = –4x + 5

slope = –4

y-intercept = 5


y = 4x + 5

slope = 4

y-intercept = 5

Answers

Answer: y = -2x + 5

Step-by-step explanation:

y = -2x + 5

slope = -2

Slope intercept form of equation of line is given by y = mx + c

where m is the slope of line

c is the y intercept i.e point where given line intersect y axis.

________________________________________________

given equation 4x + 2y = 10

we have to re-write this equation in form y = mx + c

4x + 2y = 10

subtraction 4x from LHS and RHS

4x + 2y - 4x= 10 - 4x

2y = 10- 4x

we have to eliminate 2 from y for that we

divide  LHS and RHS by 2 we

2y /2 = 10/2- 4x/2

y = 5 - 2x

rearranging it in y = mx+c form

y = -2x + 5

thus, m = -2 , c = 5

Answer:

y=-2x+5, slope= -2, y-intercept= 5 (so, first option)

Step-by-step explanation:

y=mx+b. m is the slope, and b is the y-intercept. to get the equation to the slope intercept form, you get y by itself- subtract 4x from both sides and then divide by 2 on both sides.
