Triangle ABD and ADC are righttriangles so u can use the Pythagorean theorem/triples. the triples are 3/4/5 and 5/12/13. 12 is 4x3, and 15 is 5x3, so BD is 3x3, which is 9. AC is 13, as it is part of the Pythagorean’s triples
We define variables:
x = represent the width of the field
y = represent the length of the field
We write the perimeter (with no fencing along the river):
2400 = 2x + y
We clear y:
y = 2400-2x
Answer:
an expression for the length of the field as a function of x is:
y = 2400-2x
Answer:
Step-by-step explanation:
We want to rewrite
in the form
We expand to get:
Regroup similar terms:
Simplify:
This is now of the form
where a=23.75 and b=76.24
Answer:
I'm not sure the answer to this
9514 1404 393
Answer:
$2838.14
Step-by-step explanation:
Fill in the values and do the arithmetic.
A = 2000e^(0.07·5)
A = 2000e^0.35 ≈ 2838.14
The value of the investment in 5 years will be $2838.14.
