Answer:

Step-by-step explanation:

Find the perimeter and area of the polygon with the given vertices P(-3,4), Q(1,4), R(-3,-2), S(3,-2)

We find the length of the sides of this polygon using the formula:

√(x2 - x1)² + (y2 - y1)2

Where (x1, y1) and (x2, y2)

P(-3,4), Q(1,4)

= √(1 -(-3))² + (4 - 4)²

= √4²

= √16

= 4 units

Q(1,4), R(-3,-2)

= √(-3 - 1)² + (-2 - 4)²

= √-4² + -6²

= √16 + 36

= √52

R(-3,-2), S(3,-2)

= √(3 - (-3))² + (-2 - (-2))²

= √6²+ 0

= √36

= 6 units

P(-3,4), S(3,-2)

= √(3 - (-3))²+ ( -2 - 4)²

= √6² + -6²

= √36 + 36

= √72 units

Answer:

for the x+27

the value of X would be 76.5 bc the whole line is 180 degrees so you do x+27+x=180 then you solve

2x=153 then divide and you get 76.5

Answer:

12

Step-by-step explanation:

Area of triangle + area of square + area of triangle = total area

(Area of a triangle: A = 1/2bh)

(Area of a square: A = bh)

Area of smallest triangle =

A = 1/2 (2) (2) = 2

Area of largest triangle=

A = 1/2 (2) (6) = 6

Area of the square =

A = 2 x 2 = 4

Total shape:

2 + 4 + 6 = 12

Answer:

x³ - 1

Step-by-step explanation:

Given

(x - 1)(x² + x + 1)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x² + x + 1) - 1(x² + x + 1) ← distribute parenthesis

x³ + x² + x - x² - x - 1 ← collect like terms

= x³ - 1

Answer:

She spent 7/15 of the day working on her project.

Step-by-step explanation:

Well we cant get a clear answer with the fractions 1/3 and 1/5, so we are going to have to turn them into equivalent fractions.

3 and 5 both have 15 LCD so:

1/3 x 5/5 = 5/15

1/5 x 3/3 = 3/15

5/15 + 3/15 = 8/15

15/15 - 8/15 = 7/15

She spent 7/15 of the day working on her project.

B. $63.19

Step-by-step explanation:

You will pay $63.19 for a item with original price of $78.99 when discounted 20%. In this example, if you buy an item at $78.99 with 20% discount, you will pay 78.99 - 15.798 = 63.19 dollars.

Option B is the 100% right answer

Answer:

Q= 5c

Step-by-step explanation:

Answer:

it 5.5⋅10−^8m

Step-by-step explanation:

Unless I'm missing something important here, you can find the difference between the two wavelengths by subtracting one from the other. Since you're interested in finding how much longer the wavelength associated with the orange light is, subtract the wavelength of the green light from the wavelength of the orange light. You know that the two measured wavelengths are 6.15 ⋅ 10 − 7 m → orange light 5.6 ⋅ 10 − 7 m → green light Therefore, the difference between the two wavelengths will be Δ wavelength = 6.15 ⋅ 10 − 7 m − 5.6 ⋅ 10 − 7 m = 5.5 ⋅ 10 − 8 m

Answer:

y = 6x - 20

Step-by-step explanation:

Perpendicular slope = 6

(3, -2)

y - y1 = m(x - x1)

y + 2 = 6(x - 3)

y + 2 = 6x - 18

y = 6x - 20

Answer:

Solution given:

equation of a line is:

y=-⅛x+4.......[1]

Comparing above equation with y=mx+c

we get

slope [m]=-⅛

let slope of another line is M

since the Lines are perpendicular

so m ×M=-1

we get

M=8

again

the another line passes through(x1,y1) (3,-2)

Equation of another line becomes:

(y-y1)=m2(x-x1)

(y+2)=8(x-3)

y+2=8x-24

8x-y=24+2

8x-y=26

[tex] \frac{8x}{26} - \frac{y}{26} = 1[/tex]

[tex] \frac{4x}{13} - \frac{y}{26} = 1[/tex]

is a required equation of a line in slope intercept form.

593.25 ≈ 593

The number of bacteria after 8 hours is 593.

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

Number of bacteria placed in petri dish = 490

Time required for bacteria to double = 29 hours

Number of bacteria after 8 hours is

⇒ [tex]490(2)^{\frac{8}{29} }[/tex]

⇒ [tex]490(2)^{0.2758}[/tex]

⇒ [tex]490(1.2107)[/tex]

⇒ [tex]593.25149[/tex]

⇒ [tex]593[/tex]

Hence  we can conclude that the number of bacteria after 8 hours is 593.
