What is the perimeter of quadrilateral HIJK, with vertices H( – 4,6), I(4,9), J(2,3), and K(7, – 4).

Answers

Answer 1

The perimeter of the quadrilateral is approximately 50.47 units

A quadrilateral is polygon which has 4 sides. The perimeter of a quadrilateral is the sum of the side - lengths of all sides of the quadrilateral .the side lengths are calculated by using the distance formula between two points on the cartesian plane which is given by [tex]{\displaystyle d={\sqrt {(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}}.}[/tex]

Given the vertices of the quadrilateral: H(– 4,6), I(4,9), J(2,3), K(7, – 4).

Let us calculate the distances of HI , IJ , JK and KH

[tex]{\displaystyle HI={\sqrt {(4-(-4))^{2}+(9-(6))^{2}}}.}[/tex]

or, HI = 17 units

[tex]{\displaystyle IJ={\sqrt {(2-(4))^{2}+(3-(9))^{2}}}.}[/tex]

or, IJ = 10

[tex]{\displaystyle JK={\sqrt {(7-(2))^{2}+(-4-(3))^{2}}}.}[/tex]

or, JK = √74 = 8.602... ≈ 8.60

[tex]{\displaystyle KH={\sqrt {(7-(-4))^{2}+(-4-(6))^{2}}}.}[/tex]

or, KH = √221 = 14.866... ≈ 14.87

Now perimeter = HI + IJ + JK + KH

or, perimeter = 8.60 + 14.87 + 10 + 17 = 50.47 units.

Therefore the perimeter of the quadrilateral is 50.47 units.

C=59(F−32)


The equation above shows how temperature F, measured in degrees Fahrenheit, relates to a temperature C, measured in degrees Celsius. Based on the equation, which of the following must be true?


A temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of 59 degree Celsius.A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit.A temperature increase of 59 degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.


A) I only

B) II only

C) III only

D) I and II only


Who ever answers this first correctly and show explanation gets brainliest

Answers

ANSWER:

d

ANSWER EXPLANATION: Think of the equation as an equation for a line

y=mx+b

where in this case

C=59(F−32)

or

C=59F−59(32)

You can see the slope of the graph is 59, which means that for an increase of 1 degree Fahrenheit, the increase is 59 of 1 degree Celsius.

C=59(F)

C=59(1)=59

Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of 95 degrees Fahrenheit.

C=59(F)

1=59(F)

(F)=95

Since 95 = 1.8, statement II is true.

The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of 59 degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:

C=59(F)

C=59(59)

C=2581(whichis≠1)

An increase of 59 degree Fahrenheit leads to an increase of 2581, not 1 degree, Celsius, and so Statement III is not true.

The final answer is D.

Answer:

D) i and ii

Step-by-step explanation:



from given equation, we can simplify =
1.8 C = F-32 .....................i
F = 1.8 C +32 ....................ii




now,  from (i)
1.8 (C+1 ) = 1.8 C + 1.8 = (F +1.8) -3.2
so increasing 1 C  equivalent to 1.8 F ........... iii

from iii,
increasing (1/1.8) C or (5/9) C equivalent to (1.8/1.8) F or 1 F


increasing (5/9)/ (5/9) or (25/81) C equivalent to 5/9 degree F
(so given iii become false)


only i and ii is true = D





How many unique trapezoids can be drawn with base angles that each measure 60° and sides that measure 4 cm, 4 cm, 8 cm, and 12 cm?

Answers

The number of unique trapezoids that can be drawn with base angles and side measures is 1

How to determine the number of unique trapezoids?

The given parameters are

Base angle = 60 degrees

Side lengths = 4 cm, 4 cm, 8 cm, and 12 cm

From the question, we understand that the given angle is the base angle

Since the base angles are equal, then the trapezoids is an isosceles trapezoid

This also means that the nonparallel sides are equal i.e. 4cm each

While the parallel sides are not i.e. 8cm and 12 cm

Hence, the number of unique trapezoids that can be drawn with base angles and side measures is 1

Abigail redecorates her house. A scale drawing of her house can be seen below. if each 6 cm on the scale drawing equals 12 ft, what are the actual dimensions of Abigail's house?

Answers

The actual dimensions of Abigail's house are 20ft, 14ft, 18ft, 16ft, 18ft.

For 6 cm in drawing his house is 12 ft on scale which is twice the drawing

This means the scale factor is 2

Therefore,

10cm = 2 × 10 = 20ft

7cm = 2 × 7 = 14ft

9cm = 2 × 9 = 18ft

8cm = 2 × 8 = 16ft

9cm = 2 × 9 = 18ft

What is scale factor?

The scale factor is the quantity that is multiplied by an object's scale to produce a separate object that has the same appearance but is a different size—either scaled up or scaled down.

To increase an object by a scale factor, measure all of its sides and multiply the result by the scale factor.

What is the scale factor?

You must specify the extent of the shape's enlargement when describing one.

The scale factor is the ratio of two dimensions such that one figure is large and another is small.

The scale factor is done due to the unpractical measurement of any figure.

Dimension in real = 6 feet

Since,

1 feet = 12 inches

6 feet = 72 inches

Dimension in drawing = 3 inches.

Scale factor = Dimension in drawing / Dimension in real

Scale factor = 3/72

Division method is used to distributing a group of things into equal parts.

Now,

The length of a bacterial cell is = 5 x 10⁻⁶ m.

The length of an amoeba cell is = 3.5 x 10⁻⁴ m.

Hence, The size of cell is calculated as =  3.5 x 10⁻⁴ ÷ 5 x 10⁻⁶

                                                            = 0.7 x 10²

Answer:

Because the graph has the parabol shape, so the equation of it has the function:

y = ax² + bx + c

Because the parabol has a peak at point (0; 9)

=> 9 = a.0² + b.0 + c

=> c = 9

=> The parabol has a function:

y = ax² + bx + 9

Because the parabol goes through point (3; 0)

=> 0 = a.3² + b.3 + 9

=> 9a + 3b = - 9 (1)

Because the parabol goes through point (-3; 0)

=> 0 = a.(- 3)² + b.(- 3) + 9

=> 9a - 3b = - 9 (2)

Plus (1) and (2):

=> 18.a = - 18

=> a = - 1

Substitute the result on (1)

=> b = 0

=> The function of the parabol: y = - x² + 9

=> a = - 1

=> Choose A. - 1
