Answer:
4: no
5: yes
6: yes
Step-by-step explanation:
exponential functions are in the form f(x)=ab^x
12*24= 288
3/5 of 45 is 27.
:)
f(x) = x^2 -5
Find f(3)
This means find x when it is 3 so just substitute 3 for x
f(3) = 3^2 -5
= 9 - 5
f(3) = 4
Answer:
The answer is 20ft
Step-by-step explanation:
Since they both cast shadows at the same time, the ratios of their height to their respective shadow length will be the same.
Hence; we'll equate both ratios to find the length.
House= 12/9
Flag pole= h/15
Equating both:
12/9 = h/15
h x 9 = 12 x 15
h = 180/9
h = 20ft

Answer:
BD = 17
Step-by-step explanation:
The Pythagorean theorem can be used twice:
BC^2 + AC^2 = AB^2
BC = √(AB^2 -AC^2) = √(25^2 -24^2) = √49 = 7
__
Likewise, ...
DC = √(AD^2 -AC^2) = √(26^2 -24^2) = √100 = 10
Then ...
BD = BC +DC = 7 + 10
BD = 17
