Answer:
Step-by-step explanation: there are 1760 yards in one mile, so therefor there are 1760
Look at the picture.
The point-slope form:
We have the points (-3, -3) and (2, 0). Substitute:
Answer:
point-slope form: 
slope-intercept form: 
standard form: 
Answer:
- here is the equation : y= 3x+10
- table: o miles would be $10, 5 miles would be $25, 10 miles would be $40.
Step-by-step explanation:
for the second part you can use the equation above and substitute the value of x in the equation to find y.
explanation: 3 dollars per mile so 5 miles costs 15 dollars but since there is a flat fee of 10 dollars it would total to 25 dollars.
Answer:
h(2)+g(2) = -3
Step-by-step explanation:
Replace the variable (t) with (
2) in the expression.
h (2) = 3 - 5
Replace the variable (t) with (
2) in the expression.
g(2) = 2(2) -5
Replace the function designators in h(2) +g(2) with the actual functions.
h(t) = 3 - 5 +2 (2) ← plug h(2) into 2(t)
Remove parentheses.
3 - 5 + 2(2)
Multiply 2 by 2
3 - 5 + 4 - 5
Subtract 5 from 3
.
-2 + 4 - 5
Add -2 and 4
2 - 5
Subtract 5 from 2
-3
The amount of the radioactive substance is 374.6 g
<h3>How to determine the amount of
radioactive substance?</h3>
The given parameters are:
- Initial, a = 424 mg
- Rate, r = 6%
- Time, t = 2 hours
The amount of the radioactive substance is calculated as:
A(t) = a(1 - r)^t
This gives
A(t) = 424 * (1 - 6%)^t
At 2 hours, we have:
A(2) = 424 * (1 - 6%)^2
Evaluate
A(2) = 374.6
Hence, the amount of the radioactive substance is 374.6 g
