Answer:
BC ≈ 14 units
Step-by-step explanation:
using Pythagoras' identity in the right triangle.
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
BC² + AB² = AC²
BC² + 18² = 23²
BC² + 324 = 529 ( subtract 324 from both sides )
BC² = 205 ( take square root of both sides )
BC = 
= 14.317.. ≈ 14 units ( to the nearest unit )
Answer:
Step-by-step explanation:
The expression 1.01-1.005 gives the amount of money, in thousands of dollars, in Carter's savings account t years after he opens it What does 1.01 represent in this expression? Choose 1 answer Carter opened the savings account I year ago ⓢ Carter's savings account had $1,010 in it when he opened it. The amount of money in Carter's savings account increase by 1% each year.
1.01 ( 1.005 )^t
standard exponential equation is
y = a (b)^x
where a = initial value
comparing the two equations
we get
a = 1.01
so, it means 1.01 means Carters saving account had $ 1010 in it when it opened
If he swan the length and the width of the pool it would be 21 x28 = 588 sq ft.
by swimming the length and the diagonal of the pool (25 ft) found that by using the pythagorean therom so now you are multiplying 21 x 25 = 525
588-525= 63 ft he is saving
