Answer:

Step-by-step explanation:
<h3><u>Formula to be used in the question:</u></h3>
<h3><u>Distance for the first 2 hours:</u></h3>
= 130 km
<h3><u>Distance for the next 3 hours:</u></h3>
Speed = 85 km/h
Time = 3 hours
So,
Distance = Speed × Time
Distance = 85 × 3
Distance = 255 km
So,
<h3><u>Total distance from home to destination:</u></h3>
= 130 + 255
= 385 km
<h3><u>Speed on the return journey:</u></h3>
Total distance = 385 km
Time = 5 hours
Speed = Distance / Time
Speed = 385 / 5
Speed = 77 km/hr

Simply because 4.135 is a larger number than 4.23.
If one of the exterior angles is 40, you can find its adjacent interior angle by subtracting 40 from 180. This is 40, so the triangle has 2 interior angles that are equal to 40. Now we have 2 of 3 interior angles. The sum of the measures of the interior angles of a triangle is 180, so we can set this equation up:
x + 40 + 40 = 180
x + 80 = 180
x = 100
So the triangle's angles have measures of 40,40 and 100 degrees.
We have the following expression:
y = logbx
We clear x of the expression.
We have then:
b ^ y = b ^ (logbx)
Rewriting:
x = b ^ y
Substituting we have:
x = b ^ 0
x = 1
Answer:
If (x, 0) lies on the graph of y = logbx, then:
x = 1
