What is the equivalent of the following logarithmic functions in exponential form 4 = log(subscript3)81?
First, realized what exponential form is and retrieve the formula. Second, use if-then statement log(subscript a)b = c equates to a^c = b. Third, plug numbers from question in the exponential form formula. Fourth, 3^4 = 3*3*3*3 = 81

A SUV travelling along a straight road has kinetic energy of 150 kJ. The brakes are applied, and it is brought to rest over a distance of 75 m. What is the average force of the car breaks?
First, identify what the question is asking. The question is asking for force of car breaks. Second, identify the right formula. This is a work formula; W=F*s. F= Force of the object and s = displacement of the object. Third, plug in values with units of what you do have. W = 150 kJ and s = 75 m. Fourth, to solve for F it must be isolated by dividing s from both sides. Fifth, F = W / s or F = 150 kJ / 75 M equates to 2 N. To check your work plug in 2N * 75 equals to 150 kJ.
By solving the inequality 4.7h < 18, the answer will be? (Round to the nearest hundredths place)
The goal is to isolated the variable "h". Set the < sign to equal sign. Divide 4.7 to both sides. 4.7h / 4.7 equals h; 18/4.7 equals The h is now isolated and your answer is h = 3.829 Check the problem and see were to round answer to. States round to the nearest hundredths. Final answer is 3.83
