Maria walked 3 km west and 4 km south calculate how far she is from her starting point.

Mathematics
1 answer:
Rufina [12.5K]3 years ago
8 0

Answer:

5 km

Step-by-step explanation:

We are given the distances walked by Maria;

  • 3 km west and 4 km south

We are required to determine the displacement from her starting point;

  • We are going to use Pythagoras's theorem;

a² + b² = c²

Taking, the distances towards south and towards west as the legs of the triangle;

Then, c² = 3² + 4²

               = 25

         c  = √25

            = 5 km

Therefore, the displacement from the starting point is 5 km

Answer:

5x - 2 = (-9x) + 8

5x + 9x = 8 + 2

14 x = 10

x = 10 / 14

x = 5/7

I need help with this question asap pleaseeeeee
Harman [31]

Answer:

y = 3\sqrt{7}

Step-by-step explanation:

The two inner right triangles are similar, thus the ratios of corresponding sides are equal, that is

\frac{y}{9} = \frac{7}{y} ( cross- multiply )

y² = 63 ( take the square root of both sides )

y = \sqrt{63} = \sqrt{9(7)} = \sqrt{9} × \sqrt{7} = 3\sqrt{7}

SSSSS [86.1K]

Answer:

The correct option is;

C) 6554

Step-by-step explanation:

The given data are;

Day,   Amount of change in Bacteria

1,            2

2,          -8

3,           32

4,          -128

Given that the data follows a geometric sequence, we have;

The first term of the series = 2, the common ratio = -4, the sum of a geometric progression is given by the following formula;

S_n = \dfrac{a \times \left (r^n - 1\right )}{r - 1}

Which gives;

S_7 = \dfrac{2 \times \left ((-4)^7 - 1\right )}{(-4) - 1} =  \dfrac{2 \times \left (-16384- 1\right )}{-4 - 1}  = \dfrac{2 \times \left (-16385\right )}{-5} = 6554

Therefore, the correct option is C) 6554.
