The Final Answer Is c. X-17
Answer:
Initial amount = 12
Rate of growth = 5%
value of the function when t t = 5 is 15.3
Step-by-step explanation:
The standard exponential growth equation is expressed as;
y = A(1+r)^t
A is the initial amount
r is the rate of growth
t is the time
Given the expression y = 12(1.05)^t
On comparing with the general formula;
A = 12
Hence the initial amount is 12
Also;
1 + r = 1.05
r = 1.05 -1
r = 0.05
r = 0.05 * 100
r = 5%
The rate of growth is 5%
To evaluate the function when t = 5, we will substitute t = 5 into the given function as shown;
Recall that y = A(1+r)^t
y = 12(1.05)^5
y = 12(1.2763)
y = 15.3 (to the nearest tenth)
When we say two angles are complementary, we mean that they add up to a right angle – 90 degrees. Now, we haven’t been given either of the angles directly, but we’ve been given their relationship, and we’ve been given the fact that they’re complementary. If we call the angle’s complement θ, we can express the fact that our angle is 78 degrees less than that with the expression (θ-78). Putting our information together, we have:
θ+(θ-78)=90
2θ-78=90
From there, it’s fairly straightforward algebra; just solve for θ. Remember though, the answer they’re looking for is the (θ-78) term, so make sure to evaluate that once you’ve found θ.
