Answer:

1) £ 30

2) 80 , £ 720

Step-by-step explanation:

1) marked price = £60

discount = 50%

discount price = 50/100 x 60 = 30

Selling price = 60 - 30 =£ 30

2) marked price = £800

discount = 10%

discount price = 10/100 x 800 = 80

Selling price = 800 - 80 =£ 720

I hope im right!

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Draw a typical approximating

Rainbow [258]

Answer: A = 58

Step-by-step explanation: The sketched region enclosed by the curves and the approximating rectangle are shown in the attachment.

From the sketches, the area will be integrated with respect to y.

To calculate the integral, first determine the limits, which will be the points where both curves meet.

In respect to y:

$2x+y^{2} = 48$

$2x= 48- y^{2}$

$x= 24 - \frac{y^{2}}{2}$

Finding limits:

$y= 24 - \frac{y^{2}}{2}$

$24 - \frac{y^{2}}{2}-y=0$

Multiply by 2 to facilitate calculations:

$48 - y^{2}-2y=0$

Resolving quadratic equation:

$y=\frac{-2+\sqrt{2^{2}+192} }{2}$

y = 6 and y = -8

Then, integral to calculate area will be with limits -8<y<6:

$A = \int {24-\frac{y^{2}}{2}-y } \, dy$

$A = 24y - \frac{y^{3}}{6}-\frac{y^{2}}{2}$

$A = 24.6 - \frac{6^{3}}{6}-\frac{6^{2}}{2}-[24.(-8) - \frac{(-8)^{3}}{6}-\frac{(-8)^{2}}{2}]$

A = 58

<u>The area of the enclosed region is 58 square units.</u>

common difference, d = -3

f1 = -13

An arithmetic sequence f(n) = f1 + d(n - 1)

so f(n) = -13 - 3(n - 1)

f(46) = -13 - 3(46-1) = -13 -3(45) = -13 - 135 = -148

Answer:

f(46) = - 148

7. The following clues are given about a bucket of bubble gum.

scZoUnD [109]

There were 472 pieces of bubble gum in the bucket

Step-by-step explanation:

The following clues are given about a bucket of bubble gum

1. There are between 400 - 500 pieces of gum in the bucket

2. The bubble gum was purchased in 4 equally-sized bags

3. The product of all the digits is 56

Let us explain how to solve the problem

∵ The number of the pieces of gum is between 400 and 500

∴ The number of pieces is 3-digit number and its hundred digit is 4

∵ The product of all digits is 56

∵ One of the digit is 4

∵ 56 ÷ 4 = 14

∴ The product of the ten digit and the one digit is 14

∵ 14 = 2 × 7

∴ The ten digit and the one digit are 2 and 7 or 7 and 2

- If the ten digit is 2 and the one digit is 7

∴ The number of pieces is 427

∵ The bubble gum was purchased in 4 equally-sized bags

- That means there were 4 pieces of bubble gum in each bag

∴ The number of pieces must divisible by 4

- The number is divisible by 4 if it is an even number and the number

formed from the ten digit and one digit is divisible by 4

∵ 427 is an odd number

∴ 427 not divisible by 4

- If the ten digit is 7 and the one digit is 2

∴ The number of pieces is 472

∵ 472 is an even number

∵ 72 divisible by 4

∴ 472 is divisible by 4

∴ There are 472 pieces of gum in the bucket

There were 472 pieces of bubble gum in the bucket
