Answer:
39.55
Step-by-step explanation:
24.99+15=39.55
That is how you get your answer :)
Answers:
- a = 475
- r = -0.5
- f(3) = 59.4
=======================================================
Explanation:
Any exponential function is of the form y = a*b^x
Comparing that to y = 475*(0.5)^x, we see that a = 475 and b = 0.5
Set b equal to 1+r and solve for r
1+r = 0.5
r = 0.5-1
r = -0.5
The negative r value tells us that the growth rate is -50%, in other words, we have a 50% decay rate. The amount drops by 50% each time x goes up by 1. This is the same as saying the amount cuts in half each time x goes up by 1.
-----------------------
Lastly, plug in x = 3 to find f(3)
f(x) = 475(0.5)^x
f(3) = 475(0.5)^3
f(3) = 59.375
f(3) = 59.4
Answer:
Step-by-step explanation:
5). ∠2 ≅ ∠6
By corresponding angles theorem both the angles will be congruent.
6). m∠3 + m∠5 = 180°
If two lines are parallel and a transverse cut these parallel lines, pair of consecutive angles in one side of the transverse are supplementary.
[Consecutive interior angles theorem]
7). Given : m∠1 = 71°
Therefore, m∠1 = m∠5 = 71°
By corresponding angles theorem ∠1 and ∠5 are corresponding angles.
