Answer:
Option 3
Step-by-step explanation:
tan33°=x/7
x=4.5
4.5^2+7^2=y^2
20.25+49=y^2
y=√69.25
y=8.3
Answer:
F(x) = 
Step-by-step explanation:
The antiderivative of a function (also called the integration of a function) is the reverse of the differentiation of that function. Given a function f(x), its integration, F(x), can be calculated as follows;
F(x) = 
From the question, f(x) = x² - 7x + 5
Therefore,
F(x) = 
F(x) = 
Where c is the constant of the integration (antiderivative).
PS: The constant of integration is used for indefinite integrals and allows to express integration of a function in its most general form.
Subtract 2.2 from both sides leaving -2n on the left and 10 on the right. from there you want to get "n" by itself so you divide both sides by -2n and you get n=-5
2.2-2n=12.2
-2.2 -2.2
-2n = 10
/-2 /-2
n=-5
Answer:
x = 9
Step-by-step explanation:
5x -11 (+11) = 34 (+11)
5x = 45
5x ÷ 5 = 45 ÷ 5
x = 9
