Answer:

answers below

Step-by-step explanation:

hi! you can plug in the x values given into the equation and solve for y to get your table values.

y=-1(0)+2

y=2

y=-1(1)+2

y=1

y=-1(3)+2

y=-1

y=-3/2 (-2) -1

y=2

y=-3/2 (0) -1

y=-1

y=-3/2 (2) -1

y=-4

hope this helps!

The measure of OH and PK are 10 and 8 respectively

<h3>Circle theorems</h3>

These are theorem used to solve for the angles in a circle. From the given diagram, the triangle OHK projects from the chord HK

This makes the triangle an isosceles triangle and since two of their sides are equal, hence OH = OK

Given that OK = 10, hence the measure of OH is 10

Similarly the measure of HP and PK are also equal

Craign has a building block in the shape of a rectangular pyramid .A net of which is shown below.If a measures 12 cm b measures

svetoff [14.1K]

Answer:

<h3>Option D) 294 sq cm is correct</h3><h3>∴ the surface area of the rectangular pyramid is 294 sq cm</h3>

Step-by-step explanation:

First we have to split the net into 4 triangles and 1 rectangle

Given a = 12 cm ,b = 6 cm and d = 13 cm

<h3>To find the surface area of the rectangular pyramid:</h3>

Now find the area of the rectangle base

$Rectangle base area=b\times a$

$= 6\times 12$

= 72 sq. cm

<h3>∴ Rectangle base area=72 sq cm</h3>

Now to find the area of the triangle on the left

$Left triangle=\frac{1}{2}(b)(d)$

$=\frac{1}{2}(6)(13)$

= 39 sq cm

<h3>∴ Left triangle=39 sq cm</h3>

Since all the triangles are congruent , you will need to multiply by 2 to get the combined area of the triangle on the left and on the right.

Area of left and right triangles= 2(39)

=78 sq cm

<h3>∴ Area of left and right triangles=78 sq cm</h3>

Find the area of the triangle on the bottom

$Bottom triangle area=\frac{1}{2}(a)(a)$

$=\frac{1}{2}(12)(12)$

= 72 sq cm

<h3>∴ Bottom triangle area=72 sq cm</h3>

Since the bottom of the triangle is congruent to the top triangle, multiply that by 2 to get a combined area of the triangle on the bottom and top

Area of top & bottom triangles=2 (72)

= 144 sq cm

<h3>∴ Area of top & bottom triangles= 144 sq cm</h3>

Finally add the area of the 4 triangles to the area of the rectangular base we get

=72 + 78 + 144

= 294 sq cm

<h3>∴ the surface area of the rectangular pyramid is 294 sq cm</h3><h3>∴ option D) 294 sq cm is correct.</h3>
