Answer:
The correct answer is:
1. Because of collinearity and supplementarity-
2. They remain along the same line.
3. The sum of them is 180 degrees.
4. Supplementarity.
5. The sum of the internal angles of a triangle is 180ª
6. Supplementarity and external angle theorem sum up the same.
7. Nothing.
Step-by-step explanation:
1. The reason why the exterior angle of 3 is 4, its because the last one is supplementary and collinear to the other.
2. Angle 3 and 4, form a collinear pair since they remain along the same line.
3. Angle 3 is supplementary to 4 because the sum of them is 180 degrees.
4. The sum of the angles are 3 and 4 is 180 because they are supplementary.
5. The sum of the angles mentioned is: 180 because of internal angle theorem.
6. It's like that because supplementarity and external angle theorem sum up the same. i.e, angle 1 + angle 2 + angle 3 = angle 3 + angle 4 =180
7. Nothing.
1 person = 130 + (60x7) + 350 = 900
4 people = 4 x 900 = 3600

Answer:
Step-by-step explanation:
The sunflower then began to grow at a rate of 2 inches per week. This means that the rate of growth of the sunflower is in arithmetic progression. We would apply the formula for determining the nth term of an arithmetic sequence which is expressed as
Tn = a + d(n - 1)
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = 25 inches
d = 2 inches
To determine the height after 7 weeks, T7
n = 7
T7 = 25 + 2(7 - 1)
T7 = 25 + 12
T7 = 37 inches
To determine the height after w weeks, Tw
n = w
Tw = 25 + 2(w - 1)
Tw = 25 + 2w - 2
Tw = 23 + 2w
You have to write the equation for a line that crosses the point (-4, -7) and is perpendicular to the line
When you have to determine a line that is perpendicular to a known line, you have to keep in mind that the slope of the perpendicular line will be the negative inverse of the first one.
If for exampla you have two lines, the first one being:
And the second one, that is perpedicular to the one above:
The slope of the second one is the negative inverse of the first one:
The slope of the given line y=-7/4+4 is m=-7/4
So the slope of the perpendicular line has to ve the inverse negative of -7/4
Considering it has to pass through the point (-4,-7) and that we already determined its slope, you can unse the point slope formula to determine the equation of the perpendicular line:
replace with the coordinates of the point and the slope and calculate:
Subtract 7 to both sides of the equation to write it in slope-intercept form:
Now you can graph both lines
