Georgia [21]

Answer:

9

Step-by-step explanation:

6.4(x)+2.8y=44.4

6.4(3)+2.8y=44.4

A function f is described by f(x)=A*exp(kx)+B, where A, B and k are constants. Given f(0)=1, f(1)=2, and that the horizontal asy
s2008m [1.1K]

Answer:

k = ln (6/5)

Step-by-step explanation:

for

f(x)=A*exp(kx)+B

since f(0)=1, f(1)=2

f(0)= A*exp(k*0)+B = A+B = 1

f(1) = A*exp(k*1)+B =  A*e^k + B = 2

assuming k>0 , the horizontal asymptote H of f(x) is

H= limit f(x) , when x→ (-∞)

when x→ (-∞) , limit f(x) =  limit (A*exp(kx)+B) = A* limit [exp(kx)]+B* limit = A*0 + B = B

since

H= B = (-4)

then

A+B = 1 → A=1-B = 1 -(-4) = 5

then

A*e^k + B = 2

5*e^k + (-4) = 2

k = ln (6/5)    ,

then our assumption is right and k = ln (6/5)

E D 1389 xo С 76.2° B А Find the value of x. O 38.1 O 30.9 69 O 61.8​
DanielleElmas [232]

Based on the intersecting secants theorem, the value of x is: B. 30.9°

<h3>What is the Intersecting Secants Theorem?</h3>

The intersecting secants theorem states that when two secants intersect, the measure of the angle they form is half the difference of the intercepted arcs.

Thus, based on the intersecting secants theorem, we would have the following:

x = 1/2(138 - 76.2)

x = 1/2(61.8)

x = 30.9°

The parabola y=x^2 is scaled vertically by a factor of 5/2. What is the equation of the new parabola?
Ray Of Light [21]
For this case we have the following transformation:
 Assume k> 0
 To graph f (x) + k, move the graph k units up.
 Applying the transformation we have:
 y = x ^ 2 + 5/2
 Answer:
 
The equation of the new parabola is:
 
y = x ^ 2 + 5/2
