The graph of a line has a slope of 3 and passes through the point (-4,-5).
What is the equation of the line in point-slope form?

Answers

Answer:

3x - y + 7 = 0

Step-by-step explanation:

The given point is , ( -4 , -5) and the slope is 3. The point slope form is ,

=> y - y₁ = m( x - x₁)

=> y - (-5) = 3 { x - (-4) }

=> y +5 = 3( x + 4 )

=> y + 5 = 3x + 12

=> 3x - y + 12 - 5 = 0

=> 3x - y +7 = 0

Hence the equation of the line is 3x - y + 7 = 0 .

Maria had $22.45 to spend on groceries. After buying 3 bags of chips, she had $10.60 left. If each bag of chips costs the same amount, what is the price of one bag of chips

Answers

Answer:

$3.95

Step-by-step explanation:

Take the amount she has to spend and subtract the amount left ($10.60) and that will leave you with $11.85.  So this is  how much was spent on the 3 bags of chips. To find how much each bag cost, divide $11.85/3 bags = $3.95 per bag.

A. P(EC).
B. P(EUE).
C. P(EC ∩ FC).

Answers

Answer:

A. P(EC) = 0.4  

B. P(E∪E) = 0.75

C. P(EC ∩ FC) = 0.25

Step-by-step explanation:

Let us calculate -:

we are given with - P(E) = 60 and P(F) =.15,

Thus , (a) [tex]P(E^C)=1-P(E)[/tex]

                   [tex]=1-0.6[/tex]

                   [tex]=0.4[/tex]

(b) P(E∪F) = P(E) + P(F)

   = 0.60 + 0.15

   = 0.75

(c) [tex]P(E^C[/tex]∩[tex]F^C)[/tex] [tex]=1-P(E[/tex]∪ [tex]F)[/tex]

   [tex]=1-0.75[/tex]

   = [tex]0.25[/tex]

Hence , the answers are -A. P(EC) = 0.4  , B. P(E∪E) = 0.75  , C. P(EC ∩ FC) = 0.25.

At the city Museum child admission is $6.40 in adult admission is $9.70 on Sunday 149 tickets were sold for a total sales of $1145 how many adult tickets were sold that day

Answers

Answer:

Adult=58

Step-by-step explanation:

c=child, a=adult

6.4c+9.7a=1145 equation 1

c+a=149 equation 2

a=149-c modified equation 2 to isolate a

6.4c+9.7(149-c)=1145 substitute value of a from equation 1 into equation 2

6.4c+1445.3-9.7c=1145

-3.3c=-300.3

I will use  x² + y² = (2D Hyp)²  and (2D Hyp)² + z² = (3D Hyp)²

which is just x² + y²  + z² = (3D Hyp)²

How many mL (milleters) are in 12.9 liters?

1. 129 mL
2. 1,290 mL
3. 12,900 mL
4. 129,000 mL


please help ASAP!

Answers

Given statement solution is :-12.9 liters are in milleters is  12,900 mL.

The metric system uses millilitres as the unit of volume, denoted by the letters ml or mL. One cubic centimetre, or one thousandth of a litre, is equivalent to one millilitre. That's a little sum in the imperial system.

A measure of volume in the metric system. One thousand milliliters equal one liter. Additionally known as cc, mL, and cubic centimetre.

To convert liters to milliliters, you need to multiply the number of liters by 1,000, since there are 1,000 milliliters in a liter.

So, multiplying 12.9 by 1,000 will give you the answer to how many millilitres are in 12.9 litres:

12.9 litres x litres per 1,000 = 12,900 mL

Therefore, option 3: 12,900 mL, is the milleters right response.

What  is Quadrilateral?

A quadrilateral is a four-sided polygon in geometry with four sides and four vertices. The Latin words quadri, which means "four," and latus, which means "side," are the sources of the word. Similar to other polygons like the pentagon, it is also known as a tetragon, derived from the Greek words "tetra," which means "four," and "gon," which means "corner" or "angle." It is also known as a quadrangle or a 4-angle because the word "gon" means "angle."

Given figure with coordinates

(-a, 0), (-2a, a), (-a, 2a), (0, a)

from coordinates length of side can be calculated excluding negative sign,

side = (y₂ - y₁)/(x₂ - x₁)

AB = (a - 0)/(-2a + a) = -1

BC = (2a - a)/(-a + 2a) = 1

CD = (a - 2a)/(0 + a) = -1

DA = (a - 0)/(0 + a) = 1

excluding negative sign for length all sides are equal

it is a Square: A regular polygon with four sides of equal length and angles of equal length of 90 degrees each is called a square.

Hence the figure is Square.

Please help me with my math guys really need it Batteries, Offshore Wind Lead Clean Energy Cost Cuts As Renewables by Mike Scott Batteries, Offshore Wind Lead Clean Energy Cost Cuts As Renewables Continue To Undercut Coal And Gas Batteries can store energy from solar or wind farms for use when the wind is not blowing or the sun is not shining. The transition to a low-carbon energy system is a few steps closer after two technologies that were immature and hugely expensive only a few years ago saw spectacular gains in cost-competitiveness in the last year. New research from Bloomberg NEF (BNEF) shows that the cost of lithium-ion batteries has fallen by 35% over the past year to $187/MWh, while the cost of offshore wind is almost a quarter (24%) lower than this time 12 months ago.Meanwhile, the costs of installing the more established technologies of onshore wind and photovoltaic (PV) solar also continued to fall. The levelized cost of energy for onshore wind projects starting construction at the start of this year was $50/MWh, 10% lower than a year ago, while solar projects are 18% cheaper at 57/MWh. Elena Giannakopoulou, head of energy economics at BNEF, commented: "Looking back over this decade, there have been staggering improvements in the cost-competitiveness of these low-carbon options, thanks to technology innovation, economies of scale, stiff price competition and manufacturing experience. "Our analysis shows that the LCOE per megawatt-hour for onshore wind, solar PV and offshore wind have fallen by 49%, 84% and 56% respectively since jobs that coal-and gas-fired power stations and nuclear, currently do. Battery energy storage co-located with solar and wind farms are starting to be competitive with coal and gas power, even without subsidies, in providing "dispatchable power" that can be delivered when it is needed, rather than only at the time it is being generated when the wind is blowing or the sun is shining. Battery storage can provide back-up power for renewable projects for anything from one to four hours at a time, BNEF says. Tifenn Brandily, energy economics analyst at BNEF, said: "Solar PV and onshore wind have won the race to be the cheapest sources of new 'bulk generation' in most countries, but the encroachment of clean technologies is now going well beyond that, threatening the balancing role that gas-fired plant operators, in particular, have been hoping to play." The advance of offshore wind is also hugely significant, because the technology has long been seen as an expensive generation option in the near term compared to onshore wind or solar PV, although it was hoped that in time the possibility of using bigger turbines and floating platforms, coupled with the stronger and steadier winds at sea would lead to sharp cost reductions. But those costs have come down much more quickly than forecast thanks to technological advances, larger turbines and auction programs for new capacity - offshore wind is now below $100/MWh globally, with some European projects coming in well below that, compared to more than $220 just five years ago. Siemens Gamesa has just announced its 10MW turbines will be used in the world's first subsidy-free offshore wind project, Vattenfall's Hollandse Kust Zuid 1 & 2 scheme. "The low prices promised by offshore wind tenders throughout Europe are now materializing, with several high-profile projects reaching financial close in recent months. Its cost decline in the last six months is the sharpest we have seen for any technology,"Giannakopoulou said. What type of cost are batteries for the renewable-energy industry?
