1 answer:
lana [24]3 years ago
3 0

Answer:

0ft and 60ft

Step-by-step explanation:

Given

The attached function

Required

Determine the valid values of the domain of the function

To do this, we simply consider the starting point and the end point of the trajectory on the x-axis (i.e. the horizontal distance).

From the attached graph, the horizontal distance starts from 0 and ends at 180.

This implies that the domain is: 0 \le x \le 180

From the options, the values that fall in this bracket are 0ft and 60ft

OLEGan [10]

Answer: 1 : 1.48

Step-by-step explanation:

Adam was able to change £400 into 592 francs which means that the British pound is stronger because it was able to buy more Swiss francs.

The exchange rate can be gotten using direct proportion:

400 : 592

1       : x

Cross multiply:

400x = 592

x = 592/400

x = 1.48

Exchange rate is:

= 1 : 1.48

tino4ka555 [31]

Answer:

Riko is wrong

Step-by-step explanation:

To find the distance of two point, we use the following formula:

A (x1, y1)

B (x1, y2)

AB = \sqrt{(x2-x1)^{2} + (y2-y1)^{2}  }

In this situation, we have:

A (-2,-3)

B  (2,-5)

So the distance is: \sqrt{(2 - (-2))^{2} + (-5 - (-3))^{2}  } = \sqrt{4^{2} + 8^{2} } = \sqrt{80} = 4\sqrt{5}

Hope it will find you well.
