Answer:

A. x=√60

Step-by-step explanation:

Divide 4 in half because you are solving half of an isosceles triangle

You formula is x²+2²=8²

Square root what you can: x²+4=64

Isolate the variable: x²=60

Square root both sides, x=√60

The two functions are

y= f(x), ------------(1)

g(x)= f(x+2)---------(2)

⇒Consider a point (a,b) on the curve.It will satisfy (1).

b = f(a)

Now the point a is translated by 2 units right in horizontal direction and there is no vertical shift.

Coordinate of new point = (a+2,b)

Putting the value of new coordinate in equation (1), we get

b = f(a+2)

which gives equation (2), which is

g(x)= f(x+2)

Option (3) is correct,which is, the graph of g(x) is graph of f(x) translated 2 units right.

Caroline replaced the original factory tires (P240/75 R 16) on her pickup truck with P290/70R16 tires. If the speedometer on Cas

Irina-Kira [14]

Answer:

Cassie is traveling 63.6 mph

Step-by-step explanation:

If the three numbers, left to right, are A, B, C, then the tire radius in millimeters is ...

A×B/100 + 12.7×C

For the factory tires, the tire radius is ...

240·75/100 + 12.7·16 = 180 +203.2 = 383.2 . . . . millimeters

For the replacement tires, the tire radius is ...

290·70/100 +203.2 = 406.2 . . . . millimeters

The speedometer is calibrated based on the number of revolutions the tire makes in a given time period. If the truck goes farther for each revolution, its speed is higher by the same proportion.

If the speedometer on the truck with these replacement tires reads 60 mph, the actual speed is ...

(406.2/383.2)×60 mph = 63.6 mph

_____

Comment on the problem statement

Caroline's truck has the replacement tires. If Cassie's speedometer reads 60 mph, we have no reason to assume Cassie is traveling at any speed other than 60 mph.
