Answer:
88
Step-by-step explanation:
f(t) = 103 / ( 1 + 26 * [tex]e^{-0.3t}[/tex])
here t = 17 years
f(17) = 103 / ( 1 + 26 * [tex]e^{-0.3*17}[/tex])
= 103 / (1 + 26 * [tex]e^{-5.1}[/tex])
= 103 / (1 + 26 * 0.00610)
= 103 / (1 + 0.1586)
= 103 / 1.1586
= 88.9003

Complete the equation of the line through (-10,-7)(−10,−7) and (-5,-9)(−5,−9)
y : ?
Answer:
-19
Step-by-step explanation:
becuase its -19
[tex](x_1,y_1) = (-10,-7),~~(x_2, y_2) =(-5,-9)\\\\\text{Slope,}~ m =\dfrac{y_2 -y_1}{x_2 - x_1} =\dfrac{-9+7}{-5+10} = -\dfrac{2}{5} \\\\\\\text{Equation of line:}\\y -y_1 = m(x-x_1)\\\\\implies y +7 = -\dfrac{2}5 \left(x+10 \right)\\\\\implies 5y+35 = -2x -20\\\\\implies 5y+2x +35 +20 =0\\\\\implies 2x +5y +55=0[/tex]

3.2 pounds * $4.9 = $15.68
aka amount times price per pund = total price
F $15.68
[tex]\frac{n^5}{n-6} * \frac{n^2-6}{n^8}[/tex]
Step-by-step explanation:
Dod you mean
[tex] = \frac{ {n}^{5} }{ {n}^{ - 2} } \times \frac{ {n}^{2 - 6} }{ {n}^{8} } [/tex]
[tex] = {n}^{5 - ( - 2)} \times {n}^{2 - 6 - 8} [/tex]
[tex] = {n}^{7} \times {n}^{ - 12} [/tex]
[tex] = {n}^{7 + ( - 12)} [/tex]
[tex] = {n}^{ - 5} = \frac{1}{ {n}^{5} } [/tex]
Alek is using synthetic division to divide x^3+4x^2-43x-10 by x-5.
-
-
Which answer is correct?
The answer to the synthetic division is [tex]x^{2}[/tex]+9[tex]x[/tex]-2+0/x-5
A synthetic division is shorthand method used to divide a polynomial function by a binomial in the form x-c where c is a constant
To divide a polynomial function by a binomial x-c, we set up as though we are doing long division in the form,using our question above;
x-5[tex]\sqrt[/tex][tex]x^{3}[/tex]+4[tex]x^{2}[/tex]-43x-10
To divide using synthetic division, we set aside the coefficients of the dividend and the divisor then multiply with the divisor in this form:
5[tex]\sqrt[/tex]1 4 -43 10
5 45 10
1 9 2 0
The quotient would then be based on the above; [tex]x^{2}[/tex]+9[tex]x[/tex]-2+0/x-5
We apply the values under the line as our new coefficients for the quotient but note from answer that the quotient's degrees is one less than the dividend's degrees.

In 2012, the population of a city was 5.43 million. The exponential growth rate was 1.39% per year.
a) Find the exponential growth function.
b) Estimate the population of the city in 2018.
c) When will the population of the city be 9 million?
d) Find the doubling time
a) The exponential growth function is P(t) = where t is in terms of the number of years since 2012 and P(t) is the population in millions.
(Type exponential notation with positive exponents. Do not simplify. Use integers or decimals for any numbers in the equation.)
Answer:
In 2012, the population of a city was 6.03 million. The exponential growth rate was 3.89% per year. Find the exponential growth function. Estimate the population of the city in 2018. When will the population of the city be 8 million? Find the doubling time. The exponential growth function is P(t) = 6.03e^0.0389t, where t is in terms of the number of years since 2012 and P(t) is the population in millions. (Type exponential notation with positive exponents. Do not simplify. Use integers or decimals for any numbers in the equation.) The population of the city in 2018 is 7.6 million. (Round to one decimal place as needed.) The population of the city will be 8 million in about 7.3 years after 2012. (Round to one decimal place as needed.) The doubling time is about years. (Simplify your answer. Round to one decimal place as needed.)

Answer:
Step-by-step explanation:
One
The y intercept is (0,35).
Two
The y intercept is the point that shows where the line cuts the y axis. It looks to me like it is about (0,35) as was stated above.
Two
You need to find the slope from one of the two points you are given. The other point is the y intercept.
Givens
(0,35)
(3,42.5)
Formula
m = (y2 - y1)/(x2 - x1)
Solution
y2 = 42.5
y1 = 35
x2 = 3
x1 = 0
m = (42.5 - 35) / (3 - 0)
m = (7.5 / 3)
m = 2.5
