Answer:
19. 5 feets
Step-by-step explanation:
Shadow of tree = 26 feets
Height of flower = 3 feets
Shadow of flower = 4 feets
Height of sun Innthe sky:
Shadow of flower / height of flower
= 4/3 = 1.333333
Height of tree:
Shadow of tree / height of sun
26 feets / 1.33333
= 19.5 feets
Hence, height of tree = 19.5 feets

Answer:
The equation to represent the rate of receding water level is L = 34 
.
Step-by-step explanation:
Given as :
The initial level of water in river = 34 feet
The rate of receding water level = 0.5 foot per day
Or, The rate of percentage of receding water level = 50 % per day
Let the level of water after d days = L
Now,
The level of water after d days = initial level of water × ( 
I.e L = 34 × ( 
∴ L = 34 ×
Hence The equation to represent the rate of receding water level is L = 34 . Answer
Answer:
1 false
2 true
3 true
4 false
5 true
Step-by-step explanation:
f(a) = (2a - 7 + a^2) and g(a) = (5 – a).
1 false f(a) is a second degree polynomial and g(a) is a first degree polynomial
When added together, they will be a second degree polynomial
2. true When we add and subtract polynomials, we still get a polynomial, so it is closed under addition and subtraction
3. true f(a) + g(a) = (2a - 7 + a^2) + (5 – a)
Combining like terms = a^2 +a -2
4. false f(a) - g(a) = (2a - 7 + a^2) - (5 – a)
Distributing the minus sign (2a - 7 + a^2) - 5 + a
Combining like terms a^2 +3a -12
5. true f(a)* g(a) = (2a - 7 + a^2) (5 – a).
Distribute
(2a - 7 + a^2) (5) – (2a - 7 + a^2) (a)
10a -35a +5a^2 -2a^2 -7a +a^3
Combining like term
-a^3 + 3 a^2 + 17 a - 35
