3. =1260
Step-by-step explanation:
3.= 9×(32+108)
= 9×140
= 1260 .
k = 
using the ' laws of logarithms '
log x - log y = log ( 
)
logx = logy ↔ x = y
logk - log(k - 2) = log5
log ( 
=log 5
= 5
5(k - 2) = k
5k - 10 = k
4k = 10 ⇒ k = 
=
Answer:
Its the bottom graph on the left.
Step-by-step explanation:
f(x) = (x - 2)^2 + 1
The AXIS of symmetry is x = 2.
Answer:
g(x) = 4, 6, 9, 13.5 for the x-values given
Step-by-step explanation:
The table and graph are attached.
Answer:
5cm
Step-by-step explanation:
To find the missing side we use the hypotenuse theorem.
a^2 + b^2 = c^2
The longest side of the triangle would be c. So substitute the numbers into the variables.
a^2 + 12^2 = 13^2
a^2 = 13^2 - 12^2
a^2 = 169 - 144
a^2= 25
a = √25
a=5
The missing leg's length is 5cm
