Ascuba diver is 15.5 feet below the surface of the water. if the diver continues to swim downward at a rate of 2.5 feet per second, what integer represents her location relative to the surface after 7 seconds?

- 33

Step-by-step explanation:

Since, the speed of scuba diver = 2.5 feet  per second

Thus, the distance covered by her in 7 second = 2.5 × 7 = 17.5 feet

But, According to the question,

She is 15.5 feet below the surface of water when she start swimming.

Thus, her total distance from the surface of water after 7 second

= Her distance from the surface when she start + the distance cover by her in 7 second

= 15.5 + 17.5 = 33 feet.    

Thus, -33 represents her location relative to the surface after 7 seconds when we take surface as x-axis.

step-by-step explanation:

do it yourself, cause that made me do it myself today, in english!

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
