Answer:

Percentage change in price = 13.80%

Step-by-step explanation:

Given that:

Original price = £57.99

Decreased price = £49.99

Difference = Original price - Decreased price

Difference = 57.99 - 49.99

Difference = £8.00

Percent change = \frac{Difference}{Original\ price}100

Percent change = \frac{8.00}{57.99}*100

Percent change in price = 13.80%

Hence,

Percentage change = 13.80%

Firdavs [7]
The distance covered by the hiker if he traveled a horizontal distance of 120 ft at and angle of 6° will be given by:
cos θ=adjacent/hypotenuse
let the hypotenuse be h, adjacent =120 ft, θ=6°, thus plugging in the values we shall have:
cos 6=120/h
h=120/cos 6
h=120.661 ft
Answer: 120.661 ft

Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line. y = 1 + sec
masha68 [24]

Using the washer method, the volume is given by the integral

\displaystyle\pi\int_{-\pi/3}^{\pi/3}\bigg((3-1)^2-((1+\sec x)-1)^2\bigg)\,\mathrm dx=2\pi\int_0^{\pi/3}(4-\sec^2x)\,\mathrm dx

where 3 - 1 = 2 is the distance from <em>y</em> = 3 to the axis of revolution, and similarly (1 + sec(<em>x</em>)) - 1 = sec(<em>x</em>) is the distance from <em>y</em> = 1 + sec(<em>x</em>) to the axis. The integrand is symmetric about <em>x</em> = 0, so the integral "folds" in on itself, and the integral from -π/3 to π/3 is twice the integral from 0 to π/3.

So the volume is

\displaystyle2\pi\int_0^{\pi/3}(4-\sec^2x)\,\mathrm dx=2\pi(4x-\tan x)\bigg|_0^{\pi/3}=\boxed{\dfrac{8\pi^2}3-2\pi\sqrt3}

The angle measurement in the diagram are represented by the following expressions.
PSYCHO15rus [73]

The value of x=9° and ∠B=40°

Step-by-step explanation:

From angles relationship, ∠A =∠B=corresponding angles

5x-5°=3x+13°

5x-3x=13°+5°

2x=18°

x=18/2 =9°

∠B=3x+13°= 3×9°+13° = 27° +13° =40°

What fraction of 30 is 12
zloy xaker [14]

Call the mystery fraction ' F ' (for 'fraction').

12 is the mystery fraction of 30 .

                                             12  =  F x 30

Divide each side by  30 :      F  =  12/30  =  2/5 .
