A boat starts from a port and moves 12 miles north and then moves 5 miles east. what is the present distance of the boat from th
disa [49]
If you sketch the path of the boat, you will form a right triangle towards the port. The distance from the port to the present position is the hypotenuse since it is opposite from the right angle formed by the 12 miles north and 5 miles east movement. Since it is a right triangle, use the Pythagorean Theorem to solve the hypotenuse.

Solution:

h² = o² + a²
h² = 12² + 5²
h² = 144 + 25
h² = 169
√h² = √169
h= 13

The present distance of the boat from the port is 13 miles.

PLEASE HELP ME OUT!!!!!!!!!!
Semmy [17]

Answer:

Exponential

Step-by-step explanation:

- Linear is a straight line no matter what.

- Quadratic lines makes a u or v shape that opens up, down, left, or right.

- Exponential is like a slanted 45° clockwise u and a bit stretched horizontally.

- Square root lines on a graph, looks more like a slanted L 90° clockwise.

- Inverse Variation would show its inverse, same as a mirror, it would be something similar to a hyperbola.

Hope This Helps!

Maths question I'm struggling with.
Alex17521 [72]

Answer:

A = 2.63

B = 2

Step-by-step explanation:

To find the population density, what we need to do simply is divide the population by the area of the UK

mathematically, that would be;

(6.41 * 10^7)/243,610 = 263.125

To the nearest whole person= 263 people/ square meter

So now we want to write 263 in standard form = 2.63 * 10^2

So this means A = 2.63 and B = 2

Please help me solve. Surface area of this pyramid?
Sever21 [200]

Answer:

4,784ft^2

Step-by-step explanation:

Well in this case we will just use the square and triangle area formulas instead of the pyramid surface area formula.

So if the base is a square then the area is 32*32 which is 1,024.

Now for the trangle, the area of a triangle b*h/2.

So b*h is 47*32 which is 1,504.

So 1,504/2 is 752.

So 752 is the area of 1 triangle and we have 4 so 5*752 is 3,760.

So 3,760 + 1,024 is 4,784.

So the total SA if the pyramid is 4,784ft^3.
