Equation of a line is given by y = mx + c; where m is the slope and c is the y-intercept.
Parallel lines has equal slopes.
Line y = -1/2x + 2 has a slope of -1/2

Required equation is y = -1/2x + 6

A) if x=4 evaluate the perimeter of the blanket. Don’t forget to include the measurement in your final answer.
Tanzania [10]
Formula for perimeter of a rectangle:  P = 2W + 2L

Here, P = 2(x-3 ) cm + 2(3x+7) cm = 2x - 6 + 6x + 14   (cm)

Combine like terms:  8x + 8   cm (simplest form)  This is the perimeter.

Now let x = 4:  P(x=4) = 8(4) + 8   cm   = 40 cm

What is the exact area of a circle with a diameter of 10 cm? a. 5πcm^2 b. 10πm^2 c. 25πcm^2 d. 100πcm^2
dalvyx [7]

Answer:

C

Step-by-step explanation:

a=\pir^2

To find the radius, divide the diameter by 2

r=d/2

r=10/2

r=5

a=\pir^2

a=\pi5^2

a=25\pi

So, choice C is correct

Hope this helps! :)

A triangular pyramid has a base with an area of 43 cm squared and lateral faces with bases of 10 cm and heights of 8.6 cm. What
Jet001 [13]

Answer:

The total surface area of triangular pyramid is 172 cm squared

Step-by-step explanation:

Triangular pyramid:

  • Number of faces 4.
  • Number of vertices of a triangular pyramid is 6.
  • The volume  is \frac13 AH. A= area of the pyramid's base and H= height of the pyramid.
  • The surface area of triangular pyramid B+L. B= area of base, L= area of lateral surface.

Given that, the area of the base is 43 cm squared. Lateral faces with bases of 10 cm and heights 8.6 cm.

The 3 sides of the triangular pyramid is triangle in shape.

The area of triangle is \frac12 \times base \times height.

The lateral surface area of the triangular pyramid is

=3(\frac12 \times base \times height)

=3(\frac12\times 10\times8.6) cm squared

=129 cm squared

The total surface area of triangular pyramid is

=Area of the base + lateral surface area

=(43+129) cm squared

=172  cm squared
