Answer:

Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to

where
P is the population
t is the time in years
a is the initial value
r is the rate of change
<u><em>Looking at the table</em></u>
For t=0
The value of P=1,000
so
substitute the value of the ordered pair (0,1,000) in the exponential equation

The initial value is a=1,000
substitute

For t=1
The value of P=1,400
so
substitute the value of the ordered pair (1,1,400) in the exponential equation

therefore
The exponential equation is

Answer:
∠ZVW= 45
∠ZWV = 31
x=1
Step-by-step explanation:
Properties of a Parallelogram ( including diagonals )
Diagonals of a parallelogram bisect each other.
The diagonals are cut into two equal parts
Opposite angles are congruent
Given this information we need to find x, ∠ZVW and ∠ ZWV
First lets find x
Like stated previously diagonals cut each other into two equal parts
That being said segment WZ ≅ segment ZY
Knowing this we create an equation
2z-1=1
step 1 add 1 to each side
-1 + 1 cancels out
1 + 1 = 2
now we have 2x = 2
step 2 divide each side by 2
2x/2=x
2/2=1
we're left with x = 1
Now lets find ∠ZVW
∠ZVW and ∠ZXY happen to be opposite angles ( opposite angles are congruent )
This means that because ∠ZXY = 45 ∠ZVW also = 45
Now lets find ∠ZWV
∠ZWV and ∠XYZ happen to be opposite angles ( like stated previously, opposite angles are congruent)
So because ∠XYZ = 31 ∠ZWV also = 31
Answer:
V(w) = 26 miles/hour
Step-by-step explanation:
Let
V(bu) upstream boat speed V(w) water speed
Speed upstream
V(bu) = 24 /144 ⇒ V(b) = 0,167 miles/min
V(bd) = 24/40 V(bd) = 0,6 miles/min
V(bd) = V(b) + V(w)
0,6 -0,167 = V(w)
V(w) = 0,433 miles/min
or equivalent in miles /hour
V(w) = 25.98 miles/hour
V(w) = 26 miles/hour
1.33sin(25) = 1.5sin(∅)
sin(∅) = (1.33sin(25) / 1.5)
∅ = sin⁻¹ [ (1.33sin(25)) / 1.5)
∅ = 22.0°
Answer:
The width is 10 and the length is 14.
Step-by-step explanation:
To draw this conclusion, first use the equation<em> A = lw = 140
.</em>
Remember the length is six less than twice the width, in other words, the length equals 2 time the width minus 6:<em> l = 2w - 6
</em>
Now you want to substitute numbers in:
140 = (2w - 6)(w)
140 = 2w^2 - 6w
2w^2 - 6w -140 = 0
w^2 - 3w - 70 = 0
Factorable by inspection!
(w - 10)(w + 7) = 0
w = 10
<em>w = -7 (nonsense - ignore)
</em>
I = 14
