It's -9 because it's 9 feet below sea level
Hello :
let : y the length and : x <span>the width
y = 2x +3.....(1)
xy = 77 .....(2)
by (1) subsct : y i n (2)
x(2x+3) = 77
2x²+3x -77 = 0
the descrimnent : b²-4ac ... a =2 b= 3 c = -77
3²-4(2)(-77) = 625 = 25²
x1 = (-3-25)/4 negatif refused
x2 = (-3+25)/4 =22/4 = 11/2
x= 5.5
y = 2(5.5) +3 =14</span>
Step-by-step explanation:
this is only simple.
on the graph we have the original coordinates and the target coordinates. and then we check the difference.
E = (-8, -9)
F = (-2, -8)
E' = (1, 1)
F' = (7, 2)
the change (shift) in the x coordinate from E to E' is
1 - -8 = 1 + 8 = +9
the change (shift) in the y coordinate from E to E' is
1 - -9 = 1 + 9 = +10
so, the translation is
(x + 9, y + 10)
let's check with F and F'
for x : -2 + 9 = 7
for y : -8 + 10 = 2
and F' = (7, 2)
all correct.
Answer:
the blank contains the term 2⁴²
Step-by-step explanation:
The Equation given in the question (2²¹ − 1)(2²¹ +1)
on evaluating the above expression,
we have
⇒ 2²¹ × (2²¹ + 1 ) -1 × (2²¹ + 1)
or
⇒ 2²¹⁺²¹ + 2²¹ - 2²¹ - 1² (using the property Xᵃ × Xᵇ = Xᵃ⁺ᵇ)
or
⇒ 2⁴² + 0 - 1
or
⇒ 2⁴² - 1
on comparing the result with LHS, we have
therefore,
the blank containing the term 2⁴²
A significant figure is the first number that isn’t 0, so in this case the first significant figure is 2. 213 rounded to 1 sig. fig is 200
