Answer:
Luis incurred 107 extra text messages.
Step-by-step explanation:
Giving the following information:
Luis's cell phone plan costs $39 per month. Text messages cost an additional $0.15 each.
<u>To calculate the number of text messages, we need to use the following formula:</u>
Total cost= 39 + 0.15x
x= number of text messages
55.05= 39 + 0.15x
16.05= 0.15x
107= x
Luis incurred 107 extra text messages.
Answer:(-5,4)
Step-by-step explanation:
Just took the test on edge
This problem involves the use of a kinematic equation since it involves the motion of an object. The equation for the height of the object is given as:
s = -<span>16*t^2+v_o*t
Also, the initial velocity, v_o, was also said to be equal to 128 ft/s.
For the first question, </span><span>the time(s) that the projectile will reach a height of 240 ft when v_o is 128 feet per second, can be solved using the given equation and the quadratic formula. The resulting quadratic equation is then </span>-16*t^2 + 128*t -240 =0, where a =16, b =128, and c =-240. The quadratic formula is equal to [-b <span>± sqrt(b^2 -4ac)]/2a. This gives two answers t = 3 seconds and t = 5 seconds. This might be because the projectile has a parabolic path, thus, it reaches the height of 240 ft, before and after it reaches a peak.
For the second question, the time it takes for the projectile to reach the ground is obtained by setting the distance, s, equal to zero. In this case, t = 8 seconds.</span>
