Answer:

t=11.9

Step-by-step explanation:

960=420(2)^t/10

2.28571429=2^t/10

add log to both sides

log(2.28571429)=10 t log(2)

divide by log 2

1.19264508= 10 /t

10(1.19264508)

11.926450779=t

Find the midpoint of the segment with the following endpoints. (10, 7) and (5, 4)

KatRina [158]

Answer:

$\frac{15}{2} , \frac{11}{2}$

Step-by-step explanation:-

To find the midpoint, the equation we use is:-

$\frac{x1 +x2}{2} , \frac{y1 + y2}{2}$

x1 = 10

x2 = 5

y1 = 7

y2 = 4

Substituting the values in the equation, we get:-

$\frac{10+5}{2} , \frac{7+4}{2}$

Coordinates of the midpoint---> $\frac{15}{2} , \frac{11}{2}$
