Answer:

The answer is the square root of 53, or about 7.28.

Step-by-step explanation:

To find the distance between two points, you use the formula $\frac{y_{2} -x_{2}}{y_{1} -x_{1} }$ . When we insert the coordinates given, you get the square root of 53, or 7.28.

Answer:

Step-by-step explanation:

$f(x)=4x-9$

f(-6), f(4)

Put x = -6 and x = 4 to the equation of the function:

$f(-6)=4(-6)-9=-24-9=-33\\\\f(4)=4(4)-9=16-9=7$

A deep-sea diver dived off a boat to a depth of -45 feet. What is the absolute value that expresses the distance the diver went?

Vlad1618 [11]

45 feet.

Absolute value is the distance of a number from 0. Say 0 is the surface of the ocean, then the diver is 45 feet away from it. Either from above or below, they are the same distance away.

A map has a scale of 1:125 000. What length on the map represent an MRT Track that is 10 km long?

liubo4ka [24]

A scale of 1:125000 means that for any length that is on the map, the real life length is 125000 times as long. This also means that for any length in real life, the length on the map is 1/125000 times as long.

So, a real life length of 10km will be represented by a map length of 10km/125000 = 0.00008km = 8cm

PLEASE HELP ASAP!!!! I GIVE A BRAINLIEST TO THE RIGHT ANSWER!!!!

Use cosine law to solve the problem. See image attached.
What we're looking for is the length of side A (a side which is opposite with angle A).

This is the formula of cosine law
A² = B² + C² - 2BC cos A

Input the numbers
A² = 75² + 90² - 2(75)(90) cos 85°
A = $\sqrt{75^{2}+90^{2}-2(75)(90)cos85^{0}}$
A = $\sqrt{90^{2}+75^{2}-2(90)(75)cos85^{0}}$
