What is the slope of a line perpendicular to the line in the graph?

Mathematics

BigorU [14]3 years ago

To find the answer, we can use the slope formula:

\frac{y1 - y2}{x1 - x2}
Where x and y are y coordinates and x coordinates respectively.

To find the answer, put any two points into the formula.

In this case, (1,-3) and (0,-1) will be used:

x1 and y1 would be the x and y coordinate in the first point(1,-3), while x2 and y2 would be the x and y coordinate in the second point (0,-1)

To find the answer, put any two points into the formula.

In this case, (1,-3) and (0,-1) will be used:

x1 and y1 would be the x and y coordinate in the first point(1,-3), while x2 and y2 would be the x and y coordinate in the first point (0,-1)

\frac{ -3 - ( - 1)}{ 1- 0} \\ = \frac{-3 + 2}{1} \\ = \frac{ -1}{1} \\ = -1

Therefore the answer is -1.


Hope it helps!

Step-by-step explanation:

84*66 for the rectangle and since there is two semi circles you could just calculate it as one so it would be 84*66+33*33*3.14 because formula for area of circle is A= pi*raduis with exponant of 2

A rectangular prism is 3 units high 2 units wide and 5 units long what is its surface area in square units
Luba_88 [7]

Answer:

62 square units

Step-by-step explanation:

The area of a rectangular prism is the sum of the areas of its six faces. Opposite faces have the same area, so it is the sum of 3 pairs of faces. The area of one face of each pair is the product of the dimensions of that face. Those three areas are ...

• L·W

• W·H

• H·L

so the total surface area is ...

A = 2(LW +WH +HL)

For hand calculation, this can be simplified a bit to ...

A = 2(LW +H(L+W)) . . . . . requires one less multiplication

For your prism, the area is ...

A = 2(5·2 + 3(5+2)) = 2(10 +21) = 62 . . . square units

Special Right Triangles: Decimal Answer ! What’s H and C ?! Help me please?! Round to the nearest tenth.
lesantik [10]

Answer:

h = 1.41

c = 3.46

Step-by-step explanation:

See the triangles diagram attached.

For the first triangle, Base = h, Hypotenuse = 2 and the angle between base and hypotenuse is 45°.

Therefore, \cos 45 = \frac{\textrm {Base}}{\textrm {Hypotenuse}} = \frac{h}{2}

⇒ h = 2 \cos 45 = \frac{2}{\sqrt{2} } = \sqrt{2} = 1.414 = 1.41 (Answer)

{Rounded to the nearest tenth}

Again in the second triangle, Perpendicular = c, Hypotenuse = 4 and the angle between base and hypotenuse is 60°.

Therefore, \sin 60 = \frac{\textrm {Perpendicular}}{\textrm {Hypotenuse}} = \frac{c}{4}

⇒ c = 4 \sin 60 = \frac{4 \times \sqrt{3} }{2} = 2\sqrt{3} = 3.46 (Answer)

{Rounded to the nearest tenth}
