Answer:
(C)4
Step-by-step explanation:
Given the line: 
The gradient of the line, 
A line perpendicular to the given line will have a gradient, 
(by definition of perpendicularity).
Therefore, a perpendicular line that passes through the point (4,1) is:
Comparing with the slope-intercept form y=mx+x, the slope of the perpendicular line, b=4.

Okay. When it comes to multiplying decimals, you multiply them just like you would do whole numbers. However, solving them by paper, you would add a decimal point into the answer, depending on how many numbers are behind the decimal point in the numbers being multiplied. In this case, the decimal point will go in front of two numbers, because there are two numbers behind the decimal point in -1.2 and 0.4. Know that the answer will be negative, because there is one negative and one positive number.
Multiply both numbers. -1.2 * 0.4 is -0.48. There. The product is -0.48.
Answer:
201.1 meters squared
Step-by-step explanation:
A= pi*r squared
Diameter= 16, to find the radius we must divide by 2
16/2=8
Radius= 8
A= pi* (8)^2
A= 201.06
The area of the circle is 201.1 meters squared.
Answer:
it`s not true that for every person, if the person is happy, the person has a large income/there are people that are happy and doesn't have large incomes
Step-by-step explanation:
let be x the group of people in the world
let be I(X)=x has a large income
let be H(x)=x is happy
Having a large income is not a necessary condition for a person to be happy.
¬∀x, H(x)-->I(x)
<em>it`s not true that for every person, if the person is happy, the person has a large income</em>
∃x / H(x)^¬I(x)
<em>there are people that are happy and doesn't have large incomes</em>
