Answer:
Step-by-step explanation:
1 grain = 6×10⁻⁶ g
- 7200 kg =
- 7200000 g =
- 7.2×10⁶ g =
- 7.2×10⁶ ÷ 6×10⁻⁶ =
- (7.2÷6)×10⁶⁻ ⁽⁻⁶⁾ =
- 1.2×10¹² grains

Answer:
y = 4x + 32
Step-by-step explanation:
Given: Temperature at sunrise = 32°F
y is the temperature after x hours of sunrise
Temperature change is 4°F/hour.
The equation of a line in slope intercept form is given by
y = mx +c
where m is the slope, which is the change in value of y to the value of x
and c is the value of y at x = 0
At sunrise, x =0 and y =32
∴ c = 32
Also we see that the change in temperature to that of time is 4/1 = 4
∴ m = 4
Substituting the values of m and c in the equation of line, we have
y = 4x +32
