Answer:

His rate of change is 7 pounds per week.

Step-by-step explanation:

Rate of change = change in weight ÷ change in time

change in weight = 188 - 167 = 21 pounds

change in time = 6 - 3 = 3 weeks

Rate of change = 21 ÷ 3 = 7 pounds/week

Answer:

He loses 7 pounds per week

Step-by-step explanation:

After 3 weeks he weighs 188 pounds.

After 6 weeks he weighs 167 pounds.

Weight loss = (188 - 167) pounds = 21 pounds

Time interval = 6 weeks - 3 weeks = 3 weeks

Rate of change = Weight loss ÷ time interval = $\frac{21}{3}$ pounds per week = 7 pounds loss per week.

What is the math answer

never [62]

Answer:

Step-by-step explanation:

The perpendicular diameter to the chord divides it into two congruent parts.

Since

VU⊥XS,
XT=3b-1,
TS=b+5,

we have that XT=TS.

Hence,

3b-1=b+5,

3b-b=5+1,

2b=6,

b=3.

So,

XT=3·3-1=9-1=8

TS=3+5=8

and

XS=XT+TS=8+8=16.
