Answer:

561 is the surface area

Step-by-step explanation:

11 x 11 is the base area which equals 121. The height is 10 and the base is 11 for the triangles so it is 11 x 10 which equals 110. We multiply that number by 4 to equal 440. 440 + 121 equals 561 so 561 is the surface area.

Answer:

Step-by-step explanation:

((10 x 11)/2) x 4

=220

220+11 x 11

220 + 121=

341

Answer:

there are about 8 angles ,God bless you

Answer:

I count 4 angles

Step-by-step explanation:

See the attached image.

Answer:

  i) 3.7 cm

  ii) 3.0 cm

Step-by-step explanation:

When you are given side lengths and angle measures, trig functions will generally be involved in solving the triangle. The mnemonic SOH CAH TOA is intended to remind you of the trig relations pertaining to a right triangle.

__

The sides adjacent to the angle and opposite the angle are given. The relevant relation is ...

  Tan = Opposite/Adjacent

  tan(63°) = k/(1.9 cm)

  k = (1.9 cm)tan(63°) ≈ 3.7 cm

The length k is about 3.7 cm.

__

Again, the tangent function can be used to solve this triangle.

  tan(42°) = (2.7 cm)/p

  p = (2.7 cm)/tan(42°) ≈ 3.0 cm

The length p is about 3.0 cm.

Answer:

H(d) = 0.3d + 12

Step-by-step explanation:

It started at 12 inches.

Then it grew 0.3 inches per day.

Let d = number of days.

The growth is 0.3 d.

Add the growth to the original length, to get 0.3d + 12.

Answer: H(d) = 0.3d + 12

The surface area of the larger pyramid is 159.21 ft²

The surface area of the small pyramid is given as:

A = 25.49 ft²

The corresponding sides of the pyramids are:

Small = 6; Large = 15

The surface area of the large pyramid is then calculated using:

Area = A * (Large/Small)²

This gives

Area = 25.49 * (15/6)²

Evaluate

Area = 159.21

Hence, the surface area of the larger pyramid is 159.21 ft²

Answer:

The orbit of 0 is the collection of all points (complex numbers) under iteration of x2 + c starting at the seed 0. The fate of the orbit is its eventual behavior. For example, the orbit may tend to a cycle of some period---its fate would then be that cycle. Or it ---may tend to a fixed point.

Answer:

11.9

Step-by-step explanation:

Pythagorean theorem:

[tex]a^2+b^2 = c^2[/tex]. where a and b are the sides and c is the hypotehnus (the side in front of the 90 degree angle)

[tex]22^2 + b^2 = 25^2\\484 + b^2 = 625\\b^2 = 625-484\\b^2 = 141\\b = \sqrt{141} \\b = 11.9[/tex]

Answer:

11.9

Step-by-step explanation:

This is a right triangle so I can solve this with the pythagorean theorem.

Set up the equation 22²+x²=25² x would be the third side

Simplify, 484+x²=625

Subtract from both sides 484-484+x²=625-484

x²=141

Find the square root of 141 to get x

The square root of 141 is approximately 11.9 rounded to the nearest tenth.

Answer:

The vertex would be (-3, -1)

Step-by-step explanation:

Since this is in vertex form already, a(x-h)^2+k  where h is the x value of the vetex, and k is y.

We would take the opposite of +3 and get -3, which gives us our x cordinate.

We don't change the k value, so it just stays -1, giving us our y value.

Therefore, the vertex is at (-3, -1)

Hope this helps!

Answer:

137 m²

Formula's:

Explanation:

⇒ area of rec + area of rec + area of rec + area of triangle

⇒ 2 * 4 + 7 * 6 + 8 * 9 + 1/2 * 6 * 5

⇒ 8 + 42 + 72  + 15

⇒ 137 m²

Answer:

137 m²

Step-by-step explanation:

Divide the figure into a triangle and 3 rectangles (see attached diagram)

Formulae

Triangle 1

⇒ area = 1/2 x (8 + 7 + 2 - 4 - 7) x 5

            = 1/2 x 6 x 5

            = 15 m²

Rectangle 2

⇒ area = 4 x (2 + 7 + 8)

            = 4 x 17

            = 68 m²

Rectangle 3

⇒ area = 2 x (7 + 8)

            = 2 x 15

            = 30 m²

Rectangle 4

⇒ area = 3 x 8

            = 24 m²

Total area

⇒ Total area = triangle 1 + rectangle 2 + rectangle 3 + rectangle 4

                      = 15 + 68 + 30 + 24

                      = 137 m²
