Answer:

A). PR = 16.13 ft

B). QR = 9.64 ft

Step-by-step explanation:

Part (A).

From the figure attached,

ΔPQR is a right triangle,

m(PQ) = 14 ft

m(QR) = 8 ft

By applying Pythagoras theorem,

Hypotenuse² = (Leg 1)² + (Leg 2)²

(PR)² = (PQ)² + (QR)²

(PR)² = (14)² + (8)²

PR = √260

= 16.125

≈ 16.13 ft

Part (B).

If PR = 17 feet

and PQ = 14 feet

By applying Pythagoras theorem in ΔPQR,

PR² = PQ² + QR²

(17)² = (14)² + (QR)²

(QR)² = 289 - 196

QR = √93

= 9.644

≈ 9.64 ft

Answer:

$y= 10x$

Step-by-step explanation:

In 2002, a robot explored a tunnel 210 feet long inside the

Great Pyramid in Egypt. The robot could travel about 10 feet per

minute.

The speed of the robot is 10 feet per minute

we need to find the equation for giving distance y

the robot travel in x minutes

to time is x minutes

Distance = speed x time

speed=10, distance is y and time is x

$y= 10x$
