Answer:
The trestle meets ground level at 0.875 units and 9.125 units
Step-by-step explanation:
Poorly formatted question.
The given equation is:

Required
The point where the trestle gets to the ground level
To do this, we set 
So, we have:

Multiply through by -1

Solve using quadratic formula:

Where:

So, we have:




Solve the fraction

Split


The ratio in it's simplest form is 4:1.
Easy, subsitute a point
we see it goes through (0,4)
so subsitte 0 for x and see if we get 4
4^0=1, nope
4^0-3=1-3=-2, nope
4^0+3=1+3=4, yep
4^(0+3)=4^3=64, noe
answer is 3rd option
f(x)=4^x+3
Answer:
50 cm² and 56 cm²
Step-by-step explanation:
The area (A) is calculated as
A =
× d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )
(2)
A =
× (8 + 2) × (5 + 5)
= 0.5 × 10 × 10
= 5 × 10
= 50 cm²
(3)
A =
× (12 + 2) × (4 + 4)
= 0.5 × 14 × 8
= 7 × 8
= 56 cm²
