Distance of the person from the building (x)
tan 24 = 20/x => x = 20/tan 24 = 44.92 ft
The height of the building above the height of the person and the distance of the person from the building forms two legs of right angled triangle.
Therefore, if h is the height of the building, then;
tan 31 = (h-20)/44.92
h-20 = 44.92 tan 31
h = (44.92 tan 31) + 20 = 26.99 + 20 = 46.99 ft
The hidden question is how much time does Bernard spend weight lifting in 1 week because the answer to jogging is already there, which is 140
1. To solve this problem, you need to remember that an exponential function has the following form:
f(x)=a^x
"a" is the base and "x" is the exponent.
2. It is important to know that the logarithmic functions and the exponential functions are inverse. Then, you have:
c=ln2
e^c=e^(ln2)
e^c=2
3. Therefore, the answer is:
e^c=2
Answer:
C. x + 5 = (x + 5) − 5, which has no solution
Step-by-step explanation:
Jenna's age Jessica's age
today x x + 5
in 5 years x+5
5 years ago x + 5 - 5
Equality x + 5 = x + 5 - 5
=> x + 5 = x
The equation is x + 5 = ( x + 5 ) -5
It depends where you introduce constant
Exponential function: f(x) = e^x
y = e^x + c ----> shift function up c units
y = e^(x−c) ----> shift function right c units
y = e^(cx) ------> dilates function horizontally by factor of 1/c
y = c e^x -------> dilates function vertically by factor of c
