The given model represents exponential growth as the base is greater than 1. Hence, the population will increase every year.
When a quantity grows or increases at a constant rate per unit of time, it is called exponential growth.Exponential decay: When a quantity decreases at a constant rate per unit of time, it is called exponential decay.The given model for population growth isy = 494.29(1.03)t, where t is the number of years since the beginning of the decade. Here, the base of the exponential is 1.03, which is greater than 1. So, the given model represents exponential growth.The annual percent increase in population is 3% (as 1.03 is a 3% increase in each year).c. We need to estimate when the population was about 590,000. To do this, we need to substitute y = 590 in the given equation and solve for t.494.29(1.03)t = 5904.31t = log(590/494.29) / log(1.03) = 12.91 years approximatelyTherefore, the population was about 590,000 in the 13th year, i.e., after 12 years (as it is given that t is the number of years since the beginning of the decade).

Answer:
$20.4
Step-by-step explanation:
20% of 17= 3.4
Add it to the initial $17 and you get $20.4
Answer: $20.40
Step-by-step explanation:
Since you're giving a 20% tip, your total will be 120% the price of the shampoo and cut.
17 * 120%
= 17 * 1.2
= 20.4
The total amount of money you spent at the salon and barbershop is $20.40
Your answer is correct :)
Last year, a property manager bought seven identical snow shovels and nine identical bags of salt. The total cost of the snow shovels was $241.50, before tax, and each bag of salt cost $6.20, before tax. This year, the property manager bought 3 identical snow shovels and six identical bags of salt. The total cost of the snow shovels was $105.57, before tax, and the total cost of the bags of salt was $39.06, before tax. Determine the item with the greatest percent increase in the price from last year. Be sure to include the percent increase for this time to the nearest percent.
Answer:
Step-by-step explanation:
The formula to approach this shall be:
( Final price - Initial price )/ Final price × 100/1 ............. 1
Hence for the snow shovels
Initial price = $241.50 for 7
Each will cost = $241.50/7
= $34.5
Final price for snow shovels
= $105.57 for 3 shovels
Each will cost = $105.57/3
= $35.19
Now considering the bags of salt
Initial price = $6.20 each
Final price = $39.06 for 6 bags
Each bag cost = $39.06/6
= $6.51
Now apply the formula in equation (1)
For snow shovels
($35.19- $34.5)/$34.5 × 100/1
= 0.69/34.5 × 100/1
= 0.02×100/1
= 2%
For bags of salt
($6.51-$6.20)/$6.20 ×100/1
0.31/6.20×100/1
0.05×100/1
= 5%
Hence from the above solution, we can now deduce that shovel increased by 2% while bags of salt went up by 5%.
For a standard normal distribution (u=0, 0=1), the area under the curve less than 1.25 is 0.894. What is the approximate percentage of the area under the curve less than -1.25? 0.894 0.394 0.211 0.106
After considering all the given data we conclude that approximate percentage of area under the curve is 10.6%, which is approximately 0.106 as a decimal or 53/500 as a fraction
In case of standard normal distribution, the area under the curve less than 1.25 is 0.894.
Then the standard normal distribution is symmetric about the mean, the area under the curve less than -1.25 is the same as the area under the curve greater than 1.25.
Hence, the approximate percentage of the area under the curve less than -1.25 is approximately
(1 - 0.894) * 100% = 10.6%,
which is approximately 0.106 as a decimal or 53/500 as a fraction

Write an equation of the line perpendicular to the given line that contains P.
Step-by-step explanation:
As the required line is perpendicular to y = (1/2)x + 5, product of slope of y = (1/2)x + 5 and required line should be - 1.
=> (1/2)m = - 1
=> m = - 2
Thus, required line is
=> y - (-8) = (-2)(x - 3)
=> y + 8 = -2(x - 3)

Need help
Answer:
∠ W = 51°
Step-by-step explanation:
Since WX is the diameter , then
∠ WYX = 90° ( angle in a semicircle )
The sum of the 3 angles in a triangle = 180° , then
x + x + 12 + 90 = 180
2x + 102 = 180 ( subtract 102 from both sides )
2x = 78 ( divide both sides by 2 )
x = 39
Then
∠ W = x + 12 = 39 + 12 = 51°
The complex number z = -1 -i is given.
a) Write down this number in the trigonometric form.
b) Calculate all the roots of √z and plot them all on the complex plane.
The trigonometric form of the complex number z = -1 - i is z = √2cis(3π/4) and the roots of √z are √2/2cis(3π/8) and √2/2cis(11π/8).
a) Trigonometric form of the complex number z = -1 - i is given by:
r = |z| = √(1²+1²) = √2θ = arctan(-1/-1) + π = 3π/4
Therefore, z = √2cis(3π/4)b)
Since, √z = (√2cis(3π/4))/2
= (√2/2)(cis(3π/4)/2), the roots of √z are given by:
√2/2cis(3π/4 + 2nπ)/2, where n = 0, 1.
Therefore, the roots are √2/2cis(3π/8) and √2/2cis(11π/8) and they are plotted as shown below:
In summary, the trigonometric form of the complex number z = -1 - i is z = √2cis(3π/4) and the roots of √z are √2/2cis(3π/8) and √2/2cis(11π/8).
