Answer:

71 mph

Step-by-step explanation:

Lets call the speed of the eastbound train E and the speed of the westbound train W.

E = W - 18

distance travelled  = speed * time

thus

Wt + Et = 320

Wt + (W - 18)t = 320

factor out t

t * (2W - 18) = 320

t = 2 hours

2 * (2W - 18) = 320

2W - 18 = 160

2W = 178

W = 89

Then, E = (89) - 18 = 71 mph

The roots of the given quadratic equation are 4.56 and 0.439.

The roots of an equation are the solution of that equation, since an equation consists of hidden values of the variable so to determine them by different processes and then the resultant is called roots.

As per the given quadratic equation,

x² - 5x + 2 = 0

The roots will be as,

x = [+5 ± √(5² - 4 × 1 × 2)]/(2 × 1)

x = [5 ± 4.1232]/2

x = 4.56,0.439

Hence "The roots of the given quadratic equation are 4.56 and 0.439".

The values of sin 2θ, cos 2θ, and tan 2θ are:

a) sin 2θ = √(3)/2

b) cos 2θ = 1/2

c) tan 2θ = √(3)

Generally, If sin θ = 1/2 and θ is in quadrant I, then θ is equal to 30 degrees.

To evaluate each expression, we can use the trigonometric identities:

a) sin 2θ = 2 * sin θ * cos θ

= 2 * (1/2) * (√(3)/2)

= √(3)/2

b) cos 2θ = cos^2 θ - sin^2 θ

= (√(3)/2)^2 - (1/2)^2

= (3-1)/4 = 1/2

c) tan 2θ = (2 * tan θ) / (1 - tan^2 θ)

The critical points of the given function are p = 2 ± √13.

A relation between a collection of inputs and outputs is known as a function.

A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

Each function has a range, codomain, and domain.

Critical function:

The key points are locations inside the function's domain where the function's nature changes.

The function stops increasing or decreasing at these places.

The function is: [tex]h(p)=\frac{p-2}{p^2+9}[/tex]

The derivative test will be applied here:

[tex]\begin{aligned}& \therefore h^{\prime}(p)=0 \\& \Rightarrow \frac{d}{d p}\left(\frac{p-2}{p^2+9}\right)=0 \\& \Rightarrow \frac{\frac{d}{d p}(p-2)\left(p^2+9\right)-\frac{d}{d p}\left(p^2+9\right)(p-2)}{\left(p^2+9\right)^2}=0 \\& \Rightarrow \frac{1 \cdot\left(p^2+9\right)-2 p(p-2)}{\left(p^2+9\right)^2}=0 \\& \Rightarrow \frac{-p^2+4 p+9}{\left(p^2+9\right)^2}=0 \\& \Rightarrow-p^2+4 p+9=0\end{aligned}[/tex]

Then,

The two quadrilaterals JKLQ and LMNP are congruent.

What is congruent quadrilaterals?

You will always have two opposite pairs of parallel sides if the two pairs of opposite sides in a quadrilateral are congruent. They must measure similarly to be considered congruent. Consider this: two congruent sides must always maintain the same separation between the opposing lines to maintain the other pair of opposite sides.

To prove that all corresponding pairs of sides and angles are congruent, you must put the interior angles and sides of one quadrilateral in correspondence with those of another.

For the given quadrilaterals JKLQ and LMNP it is given that,

JK ≅ MN, JQ ≅ NP, QL ≅ PL and  KL ≅ ML

Also,

∠J ≅ ∠N, ∠Q ≅ ∠P, ∠K ≅ ∠M, and ∠L is the common for both quadrilaterals.

Answer:

Step-by-step explanation:

To convert the amount of water in gallons to liters, we need to first convert the number of gallons to quarts and then convert the number of quarts to liters.We know that 1 gallon is equal to 4 quarts, so 4.7 gallons is equal to 4.7 gallons * 4 quarts/gallon = 4.7*4=18.8 quarts.We also know that 1 liter is equal to 1.057 quarts, so to convert the number of quarts to liters, we can divide the number of quarts by 1.057 quarts/liter: 18.8 quarts / 1.057 quarts/liter = 18.8/1.057=17.8 liters.Therefore, 4.7 gallons is equal to 17.8 liters.

Answer:

i) 960  ,    ii) 10 cm

Step-by-step explanation:

V of rectangular carton = 80 · 60 · 40 = 192 000

V of a packet of soap = 10 · 5 · 4 = 200

192 000 / 200

1920/2

960

ii)

960 : 1200 = 192 000 : x

x = 192 000 · 1200 / 960

x = 192 000 · 120 / 96

x = 240 000

80 · 60 · x = 240 000

4800 · x = 240 000

x = 240 000/4800

x = 2400/48

x = 200/4

x = 50

50 - 40 = 10

Answer:

i) 960 packets of soap

ii) 10 cm

Step-by-step explanation:

volume of cuboid = l*w*h

volume of carton = 80*60*40 = 192000 cm³

i)

volume of a packet of soap = 10*5*4 = 200 cm³

192000/200 = 960 packets of soaps

ii)

I am assuming the height is 40 cm

volume of carton/volume of a packet of soap = number of soap

x = volume of carton

x/200 = 1200

x = 1200*200 = 240000 cm³

80*60*h = 240000

4800h = 240000

h = 240000/4800 = 50 cm

50cm (desired height) - 40cm (current height) = 10cm

The graph that shows the proportional relationship between the number of liters of water (y) supplied after some time (x), is shown below.

A proportional relationship can be defined as a relationship between two variables, say x and y, in such a way that the equation, y = kx, models their relationship, where k is the constant of proportionality.

Given that the faucet supplies 12 liters of water after 3 minutes, where:

y = liters of water

x = number of minutes

Constant of proportionality, k = y/x = 12/3 = 4

The equation that describes the relationship would therefore be written by substituting the value of k = 4 into y = kx:

y = 4x

Think about the number 9. When the number 3 is multiplied by itself, the result is 9. This can be expressed as either 32 or 3 3. We refer to this as a square since there is a 2 exponent. When the exponent is now 1/2, the square root of the integer is being discussed. For instance, when n is a positive integer, n = n1/2

The value of a number's power 1/2 is the number's square root. It is the number whose product by itself yields the original number, to put it another way. It is symbolised by the character "." The number behind the square root sign is referred to as the radicand, whereas the square root symbol itself is known as a radical.

What is a rectangle?

A rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Main body:

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Let's say the width of metal w then the length will be w + 5

Now if we cut 1 inch square from the corner of the metal and then fold then the resultant cuboid will have;

Length = w+5 - 2 -= w + 3

Width = w - 2

Height = 1

So,

Volume = (w+3)(w-2)1

456 = w² - 2w + 3w - 6

w² + w - 462 = 0

By solving this

w = 21 so width will be 21 and length will be 21 + 5 = 26.
