Describe a single transformation the has the same effect as rotations a shape 90 degrees clockwise around the origin, then reflecting the result over the x-axis

Answers

Answer 1

Answer:

Answer:

reflection over the line y = x

Step-by-step explanation:

A transformation is the movement of a point from its initial location to its new location. If a shape is transformed then all its points are also transformed. Types of transformations are rotation, translation, dilation and reflection.

If apoint A(x, y) is rotated 90 degrees clockwise around the origin then the new location is at A'(y, -x). Then if the point A'(y, -x) is reflected over the x axis the new location is A" (y, x)

If a point A(x , y) is reflected over y = x, the new coordinate is A'(y , x)

A transformation that corresponds to rotating a shape 90 degrees clockwise around the origin, then reflecting the result over the x-axis is a reflection over the line y = x

One route along ﬂat terrain from Hermansville to Melville is to drive straight north from Hermansville for 120 miles to Jamestown, then, at Jamestown, to drive straight west for 80 miles to Melville. If a straight,ﬂat road existed between Hermansville and Melville,approximately how many miles long would it be?

Answers

approx. 144 mileswe can find this length by use of pythagorean's threorom. we use it because there's a 90 degree angle in the triangle, first we go due north, then turn due west.

$a^(2)$ + $b^(2)$ = $c^(2)$ , where a & b and the lines attached to the right angle, and c is the hypotenuse, also the length we're looking for.

$120^(2)$ + $80^(2)$ = $c^(2)$
14400 + 6400 = $c^(2)$
20800 = $c^(2)$
c = $√(20800)$ ≈ 144.2

Approximately 144 miles. You have to use the pythagorean theorem. a^2+b^2=c^2.
120 and 80 will be the legs, a and b. 120^2 + 80^2 = c^2. 14400 + 6400 = 20800. Remember, c is squared, so to find the answer, you need to find the square root of 20800, which is 144.222051019. Therefore, c, the road between Hermansville and Melville, would be approximately 144 miles.

Craig has £13.40 he sees this offer in a restaurant :main courses £8.90 each.Buy one main course and get the second half price. Can he afford to buy two main courses?Show your working

Answers

Answer:

Yes

Step-by-step explanation:

Full price for first course: £8.90

Half price: £4.45

One and one half times

full price is then: £13.35

Since this is less than Craig's £13.40, he can just barely afford to buy two main courses at these prices.
