Answer:

  £6/h

Step-by-step explanation:

Molly is paid £280 for 35 hours' work, so

  £280/(35 h) = £8/h

In the next 5 hours, her pay jumps to £350, so she earns at a rate of ...

  (£350 -280)/(5 h) = £70/(5 h) = £14/h

The difference in her pay rates is £14/h -£8/h = £6 per hour.

Answer: A problem is said to be intractable if there is no efficient algorithm to solve it.

Intractable problems are common. We need to discuss how we approach it when we actually encounter it.

How many colours do you need to colour a graph such that no adjacent vertices are of the same colour showed in the image below?

Conclusion : Provided the graph with a large number of vertices, we see that we are again faced with resorting to a systematic tracing of all paths, comparison of the neighbour's colours, backtracking, etc resulting in exponential time complexity once again.

The men’s world record mile run time in 1940 would have been 10.454 seconds

Here, the equation of the linear function that best fits the data (the line of best fit) is Finishing time = 10.878 - 0.0106(Year after 1900)

Let k be the finishing time in seconds and t be the number of years after 1900

So, the equation of regression line becomes,

k = 10.878 - (0.0106) t

To find the the men’s world record mile run time in 1940 first we find the the number of years (t)

t = 1940 - 1900

t = 40 years

So, the finishig time (k) would be,

k = 10.878 - (0.0106) × 40

k = 10.454 seconds

Therefore, the finishing time was 10.454 seconds

Answer:

m=20

Step-by-step explanation:

Solve the equation:

7m - 8 = 3 ( 2 m + 4)

Multiply 3 and (2m+4)

7m - 8 = 6m + 12

Add 8 to each side

7m = 6m + 20

Subtract 6m from both sides

m = 20

The measure of the exterior angle of the triangle is 139°.

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

From the two given angles are 75° and 64° and exterior angle is 2.

Now, ∠2=75°+64°

∠2=139°

Therefore, the measure of the exterior angle of the triangle is 139°.

Answer:

The answer is "4.3".

Step-by-step explanation:

Given:

[tex]\to x^3 - 5x - 59 = 0[/tex]

When [tex]x = 4.1:[/tex]  

[tex]\to f(4.1) = (4.1)^3 - 5(4.1) - 59 = -10.579[/tex]

When [tex]x= 4.2:[/tex]

[tex]f(4.2) = 4.2^3 - 5(4.2) - 59 = -5.912[/tex]

When [tex]x = 4.3:[/tex]

[tex]\to f(4.3) = -0.993[/tex] (closer to 0)

[tex]\to f(4.4) = 4.184[/tex]

When [tex]x = 4.35:[/tex]

[tex]\to f(4.35) = 1.563[/tex]

When the root is closer to 4.3 than 4.4 So, 1.563 is closer to zero than 4.184.

When [tex]x = 4.32:[/tex]

[tex]\to f(4.32) = 0.0216[/tex] close to zero.

So the answer is 4.3 to 1 decimal place.

Chart relating to the question is attached below.

Answer:

349 students

Step-by-step explanation:

Based on the chart given, we can obtain the experimental probability or proportion for the travel plan of 75 students :

Proportion who would be traveling by car :

Number traveling By car / number of samples

p(car) = 23 / 75 = 0.30666

If total number of students = 1138

Using the proportion obtained from the sample, the number of students who would be traveling by car from the population would be :

= 0.30666 * 1138

= 348.98 students

= 349 students

The limit of x approaching infinite of a function gives it's horizontal assymptote. We use this to solve the question, getting the following answer:

Because Limit of f (x) as x approaches plus-or-minus infinity = 16, the function has a horizontal asymptote at y = 16.

Horizontal asymptote:

An horizontal asymptote is the value of y given by:

[tex]y = \lim_{x \rightarrow \infty} f(x)[/tex]

In this question:

[tex]f(x) = \frac{16x^2 - 35}{x^2 - 5}[/tex]

The horizontal asymptote is:

[tex]y = \lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} \frac{16x^2 - 35}{x^2 - 5}[/tex]

Considering it is a limit of x going to infinite, we just consider the terms with the highest exponents both in the numerator and in the denominator, so:

[tex]y = \lim_{x \rightarrow \infty} \frac{16x^2 - 35}{x^2 - 5} = \lim_{x \rightarrow \infty} \frac{16x^2}{x^2} = \lim_{x \rightarrow \infty} 16 = 16[/tex]

Thus, the correct answer is:

Because Limit of f (x) as x approaches plus-or-minus infinity = 16, the function has a horizontal asymptote at y = 16.

From the graph of the function, given at the end of this answer, you can check that as x goes to infinity, y(green line) approches 16(blue line).

Answer: Let x be the number of piles of wood that Mr. Anderson made.

We know that he sold 25 pieces of wood to his neighbor, and the rest of the pieces of wood were divided into piles around his house, with each pile containing 40 pieces of wood.

Therefore, we can set up the equation:

185 pieces - 25 pieces = x * 40 pieces

Simplifying the equation:

160 = x * 40

To find the value of x, we need to divide 160 by 40

160/40 = x

x = 4

Therefore, Mr. Anderson made 4 piles of wood after he sold 25 pieces of wood to his neighbor.

It's worth noting that this equation was used to find the number of piles of wood Mr. Anderson made after selling 25 pieces to his neighbor, and assuming that he didn't use the rest of the wood for anything else except for making the piles.

Step-by-step explanation:

The number of units that tile will he need to surround his pool is 19.82units.

this question is of quadratic equation ,

The number of units of tile simply refers to the perimeter.

So, we need to find all the sides of the rectangle.

Now, we have,

AB = 4.24 units

BD = 7.07 units.

So, we can find AD using pythagoras theorem.

So,

(AD)² + 4.24² = 7.07²

(AD)² + 17.978 = 49.985

(AD)² = 49.985 - 17.978

AD = √32.007

AD = 5.66 units

AD = BC = 5.66 units

Likewise, AB = DC = 4.24 units

Thus,

perimeter = 2(5.66) + 2(4.24) = 19.8 units.

The number of units that tile will he need to surround his pool is 19.82units.

A. The function has a factor of (4x + 3).

If x=3/4 then 4(3/4)+3 which is not equal to zero

B. The function has a factor of (4x – 3).

If x=3/4 then 4(3/4)-3 which is equal to zero

C. The function has a factor of (3x + 4).

If x=3/4 then 3(3/4)+4 which is not equal to zero

D. The function has a factor of (3x – 4).

The area of ΔADC is equal to 6 unit².

The total area that is bounded by a triangle's three sides is referred to as the triangle's area. In essence, it is equal to 1/2 of the height times the base, or A = 1/2 b h.

A abc = A adc because the areas of the initial and reflected triangles are equal.

Using the formula area=1/2 base height, determine the area of triangle ABC.

ABC in a triangle:

base = 4 units + AC

height = 3 units + BE

AΔ= abc = 1/2×4×3 =6 unnit²

Hence,

 ΔADC = 6 unit²

The probability best prediction for the number of times that Ellen will draw a blue marble is 200.

Number of blue marbles: 222

Number of red marbles: 333

Total number of marbles: 555

Probability of drawing a blue marble:

222/555

= 0.4

Number of times drawing a blue marble:

300300300 x 0.4

= 120,120,120

Rounded to nearest whole number:

Ellen has a bag with 333 red marbles and 222 blue marbles in it. She is going to randomly draw a marble from the bag 300300300 times, putting the marble back in the bag after each draw. The best prediction for the number of times that Ellen will draw a blue marble is 200. This prediction is based on the fact that there are more red marbles than blue marbles in the bag. To calculate this, we first need to determine the probability of drawing a blue marble; there are 222 blue marbles out of 555 total marbles, so the probability is

222/555

= 0.4.

Multiplying this by the total number of draws (300300300) gives us 120,120,120. Rounding this to the nearest whole number gives us our prediction of 200 times.

The formula for the general formula is expressed as;

x = -b±√b²-4ac/2a

Given the expression

x²+4x+7 = 0

a = 1, b = 4 and c = 7

Substitute

x = -4±√4²-4(1)(7)/2(1)

x  = -4±√16-28/2

x = -4±√-12/2

x = -4±√4*-3/2

x = -4±2√-3/2

x = -4±2√3i/2

x = -4+2√3i/2 and  -4-2√3/2
