Answer:
A linear formula for S as a function of D is S=17D+1534
Step-by-step explanation:
We are supposed to find a linear formula for S as a function of D.
Equation of line : y = mx+c
We are given that At the surface, the speed of sound is 1534 meters per second.
c = 1534
We are given that for each increase in depth by 1 km, the speed increases by 17 m/s
So, Slope = m = 17
Substitute the values in equation
y=17x+1534
x denotes depth
y denotes speed
We are given that Use D for depth and S for the speed of sound
So, S=17D+1534
Hence a linear formula for S as a function of D is S=17D+1534
Answer:
D
Step-by-step explanation:
the y intercept is negative 3, and the line is going down, and it would be negative 3 over 2.
Answer:
9.2 (1DP)
Step-by-step explanation:
- First you do 10^2 which is 10 X 10 = 100
- Then you do 4^2 which is 4 X 4 = 16
- Then you do 100 - 16. The way Ive learnt it is that if the hypotenuse isn't the one you have to find then minus of it it is then plus. So 100 - 16 = 84
- A^2 + B^2 = C^2 84 is C^2 meaning now you have to square root it
- Square root of 84 is 9.2 to 1 DP
