Answer:
x = 49.84
Step-by-step explanation:
We are given an equation of unknown x and we have to solve the equation for x.
⇒
⇒ {Since we know that ln AB =ln A + ln B}
⇒
⇒ {Since we know that ln A/B = ln A - ln B}
⇒
⇒
⇒ {Converting logarithm to exponent form}
⇒ x = 49.84 (Approximate) (Answer)
Answer:
Company A:
Company B:
Step-by-step explanation:
The initial fee is the y-intercept, as that is the cost at x = 0, or the cost before any time has passed. Afterwards, the rate the cost increases is the slope.
Linear equation in slope-intercept form:
where m is the slope and b is the y-intercept.
Company A charges $50 up front and $40 per hour afterwards, so the equation would be:
Company B charges $25 up front and $50 per hour, so:
Answer: 6 feet from the pivot point
<u>Step-by-step explanation:</u>
Girl's weight x distance from center = Boy's weight x distance from center
65 (7) = 75x
6.066 = x
The boy needs to be placed 6 feet from the center (aka pivot point) which is the same as saying 1 foot from the end of the seesaw.
