Reflect the shape A in the line x=1

Mathematics
1 answer:
aniked [119]2 years ago
6 0

Answer:

reflected image shown in red on attached diagram

Step-by-step explanation:

When reflecting an object in the line x = a:

  • reflected x-values: 2a - x
  • reflected y-values are the same as the original y-values

So when reflecting in the line x = 1

  • given x-value = 2, so reflected x-value = 2(1) - 2 = 0
  • given x-value = 4, so reflected x-value = 2(1) - 4 = -2

(2, 7) → (0, 7)

(2, 4) → (0, 4)

(4, 4) → (-2, 4)

The base of a triangular prism is an isosceles right triangle with a hypotenuse of 72−−√ centimeters. The height of the prism is
Amiraneli [1.4K]

Answer:

Step-by-step explanation:

Surface area = lateral area + 2(area of base)

Lateral area = perimeter of base * height.

Because it is a isosceles right triangle, both sides are equal.

x^{2} +x^{2} = 72

2x^{2} = 72. Divide both sides by 2

x^{2} = 36.  Square both sides.

x = 6.

So the perimeter of the base = 6 + 6 +\sqrt{72} = 20.485281374239

Lateral area = 20.485281374239 * 7 = 143.397 cm^{2}

Area of base is (1/2)base * height.

(1/2)(6)(6) = 18

Using the surface area formula

surface area = 143.397 + 2(18) = 179.4 cm^{3}

inysia [295]

Answer:

slope=1/3

Step-by-step explanation:

the equation is in slope-intercept form (y=mx+b) and m always equals slope in that equation, so in your equation m=1/3, so slope=1/3
