What is the absolute value of negative 4 minus 9 i?

You didn't ask a question or put a picture on this

Answer:

There are 3 possible answers because you didn't state which value was base or height.

Going off the assumption that the base is 15 cm and the height is 8 cm, the area is 60 cm. (same answer if base is 8 cm and height is 15 cm)

A = 1/2(b*h)

A = 1/2(15*8)

A = 1/2(120)

A = 60

Going off the assumption that the base is 17 cm and the height is 8 cm, the area is 68 cm. (same answer if base is 8 cm and height is 17 cm)

A = 1/2(b*h)

A = 1/2(17*8)

A = 1/2(136)

A = 68

Going off the assumption that the base is 15 cm and the height is 17 cm, the area is 127.5 cm. (same answer if base is 17 cm and the height is 15 cm)

A = 1/2(b*h)

A = 1/2(15*17)

A = 1/2(255)

A = 127.5

The geometric mean should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.

Answer:

Step-by-step explanation:

The sum of the sequence is the average of first and last terms times the number of terms.

(3n+4) for 3rd and 7th terms and the number of terms is 7-3+1=5 so

(13+25)5/2

height = 30 meters

Answer:

39 degrees

Step-by-step explanation:

Vertical angles are opposite angles made by two intersecting lines, this means they share a vertex. Vertical angles are always congruent. Congruent angles have the same measurements, so the other angle must be 39 degrees.

Step-by-step explanation:a) Which of the shapes is a heptagon?

Answer:

y+2=3(x-6)

Step-by-step explanation:

y-y1=m(x-x1)

y-(-2)=3(x-6)

y+2=3(x-6)

Area of this shape = 614²

Length of side of the first square = 10

It's area :

[tex] =\tt side \times side[/tex]

[tex] = \tt10 \times 10[/tex]

[tex] = \tt {100}^{2} [/tex]

Thus, the area of the first square = 100²

Length of the side of the second square = 10

It's area :

[tex] = \tt \: side\times side[/tex]

[tex] =\tt 10 \times 10[/tex]

[tex] = \tt{100}^{2} [/tex]

Thus, the area of the second square = 100²

Length of the side of the third square = 10

It's area :

[tex] =\tt side \times side[/tex]

[tex] = \tt 10 \times 10[/tex]

[tex] = \tt {100}^{2} [/tex]

Thus, the area of the third square = 100²

(pi value = 3.14)

Radius of the first semicircle = 10 cm

It's area :

[tex] = \tt \: \frac{\pi {r}^{2} }{2} [/tex]

[tex] = \tt \frac{3.14 \times 10 \times 10}{2} [/tex]

[tex] = \tt\frac{3.14 \times 100}{2} [/tex]

[tex] =\tt \frac{314}{2} [/tex]

[tex] =\tt {157}^{2} [/tex]

Thus, the area of the first semicircle = 157²

Area of the second semi circle :

= area of the first semicircle

= 157²

Thus, the area of the second semicircle = 157²

Total area of the figure :

= Area of the 3 squares + Area of the two semi circles

[tex] =\tt 100 + 100 + 100 + 157 + 157[/tex]

[tex] = \tt300 + 314[/tex]

[tex] = \tt {614}^{2} [/tex]

Therefore, the total area of the figure = 614²

Answer: X = -4

Step-by-step explanation:

90 - 5x + 62 -2x = 180

152 - 7x = 180

-7x = 28

x = -4

Check your answer by pluging in the vaule of x

90 - 5(-4)

90 + 20 = 110

62 - 2(-4)

62 + 8 = 70

110 + 70 = 180

Checks out.

Answer: 110 degrees and 70 degrees

Step-by-step explanation:

These angles are same side (of the traversal line) interior (inside the parallel lines) angles. Same side interior angles sum to 180 degrees. Add the two angles together and set them equal to 180. (90-5x) + (62-2x) = 180

Combine like terms. 90+62= 152 and -5x + -2x = -7x rewrite the equation as 152 + -7x = 180

Subtract 152 from both sides of the equation.

-7x = 28. Now isolate x by dividing both sides by -7. X= -4. Now we can substitute -4 back into the original equations. 90 -5(-4) = 90 +20 = 110 and 62 - 2(-4) = 62 + 8 = 70

We can double check our work to see if these two indeed add up to 180. 110 + 70 = 180

Answer:

  (c)  3√3

Step-by-step explanation:

The altitude forms the long side of a 30°-60°-90° right triangle whose short side is 6/2 = 3 cm.

The ratios of side lengths in a 30°-60°-90° triangle are ...

  1 : √3 : 2

Multiplying these ratio values by 3 gives the right triangle side lengths of ...

  3 : 3√3 : 6

where 6 is the side length of the equilateral triangle. The length 3√3 is the altitude of that equilateral triangle.

The height of the triangle is 3√3 cm.
