Question 12 of 15 - Question: 2.12
2020-2021 T-Math-Alg1-T1and2-CBT: Section 2 - Calculator Section
The speed of the wind is changing according to the function () -- +30, where t time in minutes after 6:00 pm and V(t) - wind speed in mes per how) Michaec
equation V (20) - V(10) -5?
In a period of 5 minutes, the wind speed increased from 10 mph to 20 mph
The wind speed decreased by 5 mph between 6.10 p m and 6 20p. m.
The wind speed increased by 5 mph between 6:10 pm and 6:20 pm
In a period of 5 minutes, the wind speed decreased from 20 mph to 10 mph

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
