Which is the equation of the parabola

Answer:

y = -x + 2

Step-by-step explanation:

[slope-intercept form] y = mx + b

m [slope] = ∆y/∆x = y₂–y₁ / x₂–x₁

b [y-intercept] = (0,b) → x = 0.

If y = 2 when x = 0, b = 2.

Since y decreases by 1 unit everytime x increases by 1 unit

a decrease by 1 unit is represented by -1, and an increase of 1 is represented by 1.

So a decrease of -1 over an increase of 1

is -1/1 = -1 = m.

Answer:

Length of the rectangle = 16.5 feet

Step-by-step explanation:

Border length bought = 62.5 feet

Including 5 feet extra

Border length needed = 62.5 feet - 5 feet

= 57.5 feet

Border needed = perimeter of the rectangle = 57.5 feet

Width of the rectangle = 12.25 feet

Length of the rectangle = x feet

Perimeter of a rectangle = 2(Length + width)

57.5 =2(x + 12.25)

57.5 = 2x + 24.5

57.5 - 24.5 = 2x

33 = 2x

x = 33/2

x = 16.5 feet

Length of the rectangle = 16.5 feet

Answer:

So adult tickets cost £17.00 and child tickets cost £9.00

Step-by-step explanation:

2a+3c=61

2a=61-3c

a=30.5-1.5c

...

3a+5c=96, using a found above we get:

3(30.5-1.5c)+5c=96

91.5-4.5c+5c=96

91.5+0.5c=96

0.5c=4.5

c=9, and since a=30.5-1.5c

a=17

So adult tickets cost £17.00 and child tickets cost £9.00

Answer:

The adult tickets cost £17.00 and child tickets cost £9.00

Step-by-step explanation:

2a + 3c = 61

2a = 61 - 3c

a = 30.5 - 1.5c

3(30.5 - 1.5c) + 5c = 96

91.5 - 4.5c + 5c = 96

91.5 + 0.5c = 96

0.5c = 4.5

c = 9

a = 30.5 - 1.5c

a = 17

The adult tickets cost £17.00 and child tickets cost £9.00

Answer: 0.6

Step-by-step explanation:

0.6 is the probability that Nuan scans greater than 10 barcodes before the scanner misreads one.

It is a branch of mathematics that deals with the occurrence of a random event.

Given,

Nuan is using a faulty barcode scanner that misreads barcodes 5% of the time.

Let B = the number of barcodes Nuan scans until the scanner misreads one.

n=10

p=5%=0.05

Mean=1/p=1/1/20=20

Variance=1-p/p²

=1-1/20/(1/20)²

=19/20×400

=380

Standard deviation=√380=2√95=19.493

p(x=10)=0.0315

p(x<10)=0.3697

p(x≤10)=0.40126

p(x>10)=0.598

=0.6

Hence, 0.6 is the probability that Nuan scans greater than 10 barcodes before the scanner misreads one.

Answer:

Step-by-step explanation:

if you have two negatives next to eachother, the equation now adds like 5+4. 5+4=9

y = 4/3x +5 is the equation of the line that passes through the point (-3, 1) and has a slope of 4/3.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Let us use point-slope formula  y-y₁ = m(x-x₁) with point (-3,1) and slope m of 4/3.

Plug in the values

y-1 =4/3(x-(-3))

y-1 = 4/3(x+3)

Apply distributive property

y-1 =4/3x +4

Add 1 on both sides

y = 4/3x +5

Hence, y = 4/3x +5 is the equation of the line that passes through the point (-3, 1) and has a slope of 4/3.

Answer:

356

Step-by-step explanation:

To answer this, find the area of each side, then add the values together.

Normally Surface Area = 2 (wl + hl + hw) but in this case, the easiest way to solve this is to divide the shape into 2 different rectangular prisms. Your new equation would be: SA = Sa₁ + Sa₂ or it could be

SA = [2 (wl + hl + hw)] + [2 (wl + hl + hw)]

We'll start by solving the surface area for the larger rectangular prism.

Sa₁ = 2 (wl + hl + hw) substitute w, l, and h

Sa₁ = 2 [(10)(0.5) + (12)(0.5) + (12)(10)]

Sa₁ = 2 (131)

Sa₁ = 262

Now do the same equation for the smaller rectangular prism

Sa₂ = 2 (wl + hl + hw) substitute w, l, and h

Sa₂ = 2 [(10)(0.5) + (4)(0.5) + (4)(10)]

Sa₂ = 2 (47)

Sa₂ = 94

Now add Sa₁ and Sa₂

SA = 262 + 94

SA = 356

Answer:

St/EF = WR/CD

Step-by-step explanation:

The ratio of corresponding sides is same for all the sides for similar polygon. the correct proportion is,

[tex]\dfrac{ST}{EF} =\dfrac{WR}{CD}[/tex]

Thus the option H is the correct option.

To find the correct proportion we need to know about the properties of slimier polygon.

Two polygons are said to be similar or congruent pentagon-

The corresponding angle of two pentagons are congruent.

The ratio of corresponding sides is same for all the sides.

The figure given in the problem of similar two polygons with six sides.

Rearrange the second figure as shown in figure.

As for the similar polygons, the ratio of corresponding sides is same for all the sides.

Thus the sides shown in the two rearranged figure must be same. Therefore,

[tex]\dfrac{ST}{EF} =\dfrac{WR}{CD}[/tex]

Hence the correct proportion is,

[tex]\dfrac{ST}{EF} =\dfrac{WR}{CD}[/tex]

Thus the option H is the correct option.
