56,87,90,42,36,77

Answer:

slope = [tex]\frac{8}{3}[/tex]

Step-by-step explanation:

calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 5, - 4) and (x₂, y₂ ) = (- 2, 4) ← 2 points on the line

m = [tex]\frac{4-(-4)}{-2-(-5)}[/tex] = [tex]\frac{4+4}{-2+5}[/tex] = [tex]\frac{8}{3}[/tex]

Answer:

The 7th term is 896

Step-by-step explanation:

= ar^n-1

a = 14

r = 28/14

= 2

n = 7

= 14 X 2 ^ 7-1

= 14 X 2 ^ 6

= 14 X 64

= 896

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

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

Answer:Let's start b writing down coordinates of all points:A(0,0,0)B(0,5,0)C(3,5,0)D(3,0,0)E(3,0,4)F(0,0,4)G(0,5,4)H(3,5,4)a.) When we reflect over xz plane x and z coordinates stay same, y coordinate  changes to same numerical value but opposite sign. Moving front-back is moving over x-axis, moving left-right is moving over y-axis, moving up-down is moving over z-axis.A(0,0,0)ReflectingA(0,0,0)B(0,5,0)ReflectingB(0,-5,0)C(3,5,0)ReflectingC(3,-5,0)D(3,0,0)ReflectingD(3,0,0)b.)A(0,0,0)MovingA(-2,-3,1)B(0,-5,0)MovingB(-2,-8,1)C(3,-5,0)MovingC(1,-8,1)D(3,0,0)MovingD(1,-3,1)

Step-by-step explanation:

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:

  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: Both of these events are more likely.

Step-by-step explanation:

Since we have given that

Probability that she is getting injured playing volleyball = 0.1

Probability that she is getting injured playing soccer is given by

Since we need to compare both the probabilities so, for this we first need to change the second probability in decimal form.

So,

since both the events have same probability.

Hence, Both of these events are more likely.Step-by-step explanation:

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.

Step-by-step explanation:

it is a 90 degree angle so you have to figure out what something plus 10 equals and then multiply the x by 2 so basically it's a solve and answer or redo it until you get 90° for your total

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)

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

Answer:

21.5 square m

Step-by-step explanation:

You find the area of the shaded space by finding the area of the square and the removing the area of the circle.

The area for the square is 10x10=100.

All you have to do is follow the formula, (3.14)r^2. However, the 10 is NOT the diameter! The radius is half of the diameter. So, it's 3.14x5x5, which is 3.14x25=78.5.

Then, you can do 100-78.5=21.5
