2.9 cos (17) = 2.77
The value of expression 2.9 cos 17° is -0.81.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The expression is;
⇒ 2.9 cos 17°
Now,
The value of cos 17° = - 0.28

Now suppose there are more goods and services and the economy is now open to trade with other countries. Based on this generated data and since you have already calculated nominal and real GDP, you will now determine the GDP deflator, real per capita GDP, as well as the growth rates in nominal GDP, real GDP, GDP deflator (price level), and real GDP per capita for this simple economy.(Round your answer to two decimal places.)
It should be noted that GDP deflator simply measures the changes in price for goods and services.
What is GDP?Your information is incomplete as the figures aren't given. Therefore, an overview will be given.
Gross domestic product simply means the total monetary value of the finished goods and services that are produced in a country.
The formula for calculating the GDP deflator will be:
= Nominal GDP/Real GDP × 100
Also, the formula fro calculating real GDP per capita will be:
= Real GDP/Total population
In conclusion, the real GDP is the GDP of a country that has been adjusted for inflation.

Step-by-step explanation:
Sorry If I am wrong but I am sure it's right.
An exponential function is represented by the graph is f(x) = 3(3)ˣ. Therefore. option B is the correct answer.
What is the exponential function?Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).
From the given graph, the coordinate points are (0, 3) and (1, 6).
Use, the exponential growth formula f(x) = abˣ, where, r is rate of growth.
Rate = (6-3)/(1-0)
= 3
Now, substitute (x, y)= (0, 3) and b=3 in f(x) = abˣ, we get
3=a(3)⁰
a=3
Now, substitute a=3 and b=3 in f(x) = abˣ, we get
f(x) = 3(3)ˣ
Therefore. option B is the correct answer.

Selling tickets to a
performance. On
the first day of ticket sales the
school sold 8 adult tickets
and 13 student tickets for a
total of $176. The school took
in $68 on the second day by
selling 4 adult tickets and 4
student tickets. Find the
price of an adult ticket.
Answer:
9 dollars
Step-by-step explanation:
Solve with a system of equations
Let adult tickets be a and student tickets be s
1. 8a + 13s = 176
2. 4a + 4s = 68
3. s = 17 - a
Equation 2 is friendlier, so let's divide all the numbers by 4.
a + s = 17
Equation is s = 17 - a
Substitute s in equation 1
8a + 13(17-a) = 176
8a + 221 - 13a = 176
221 - 5a = 176
5a = 45
a = 9
The price of an adult ticket is 9 dollars

What is the value of pi based on the equation for the best-fit line?.
The line of best fit is used to illustrate a linear regression.
The value of pi based on the equation for the best-fit line is 3.0017
How to determine the value of piThe equation of the line of best fit is given as:
[tex]C = 3.0017 D + 0.3268[/tex]
Where:
C represents the circumferenceD represents the diameterThe circumference of a circle is calculated as:
[tex]C = \pi D + k[/tex]
Where k represents a constant.
