The distance train a travels is represented by d = 80t, where d is the distance in kilometers and t is the time in hours. the distance train b travels at various times is shown in the table. what is the rate of each train? which train is going faster? time (hours) distance (km) 2 170 4 340 5 425 the rate of train a is _km per hour. the rate of train b is_ km per hour. train _ is going faster.

step-by-step explanation:

the shape,the size and the distance

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
