Answer:
The resultant of two forces of 7N and 3N acting at a right angle to one another is √58 N.
Step-by-step explanation:
Let the magnitude of the force of 7N be denoted as “F₁” on the x-axis and the magnitude of the force of 3N be denoted as “F₂” on the y-axis.
We are given that the two forces make an angle of 90° to one another as shown in the figure attached below.
Also, in the figure, we can see that the resultant force is denoted as “F”.
Now,
The magnitude of the resultant force can be calculated by using the Pythagoras theorem,
∴ F = √[F₁² + F₂²]
⇒ F = √[7² + 3²]
⇒ F = √[49 + 9]
⇒ F = √[58] N

125 - 8 = 5³ - 2³ =
= ( 5 - 2 ) · ( 5² + 5 · 2 + 2² ) =
= 3 · ( 25 + 10 + 4 ) = 3 · 39 = 117

A ) Difference of Cubes
Answer:
The total charge for these tickets when paying by credit card is £ 90.64.
Step-by-step explanation:
Since Billy wants to buy 4 adult tickets at £ 15 each and 2 child tickets at £ 10 each for a show, and a 10% booking fee is added to the ticket price, and 3% is then added for paying by credit card, for work out the total charge for these tickets when paying by credit card the following calculation must be performed:
((4 x 15 + 2 x 10) x 1.10) x 1.03 = X
((60 + 20) x 1.10) x 1.03 = X
(80 x 1.10) x 1.03 = X
88 x 1.03 = X
90.64 = X
Thus, the total charge for these tickets when paying by credit card is £ 90.64.
The answer to this question is x=8; y= -7
