Answer:
sec theta
Step-by-step explanation:
we have this as follows;
cos theta +cos theta tan^2 theta
= cos theta (1 + tan^2 theta)
Recall;
1 + tan^2 theta = sec^2 theta
= sec^2 theta * cos theta
Recall;
sec theta = 1/ cos theta
= 1/cos theta * cos theta * 1/cos theta
= 1/cos theta = sec theta
Lana draws a triangle( LMN) on the coordinate plane. What is the perimeter of the triangle( LMN)? Round to the nearest unit.

The mean of six numbers is 8, and the mean of another four numbers is 5.
What is the mean of all ten numbers?
Answer:
6.8
Step-by-step explanation:
8 * 6 = 48 (to reverse dividing by 6 to basically un-average the 6 numbers).
5 * 4 = 20 (to un-average these numbers as well).
48 + 20 = 68
68 / 10 = 6.8
Basically by doing this you are still adding all the numbers together & then dividing by 10 as if you added them all up at once & not in a group of 6 & a group of 4.
Hope this helped. :)

The measures of interior angle of a convex pentagon are in ratio 1:2:3:4:5. Find the measures of each angle
Answer:
The angles have measurements 36, 72, 108, 144, and 180.
Step-by-step explanation:
Pentagon has 5 sides and 5 angles.
The amount of triangles formed by choosing one vertex and drawing from that vertex to every nonadjacent vertex is 3.
3(180)=540 which is the sum of the angles in a pentagon.
So since the ratio is 1:2:3:4:5, that means the angles are 1x,2x,3x,4x, and 5x.
We have the equation 1x+2x+3x+4x+5x=540 to solve.
15x=540
Divide 15 on both sides:
x=540/15
x=36
1x=36
2x=72
3x=108
4x=144
5x=180
The angles have measurements 36, 72, 108, 144, and 180.

Milan is participating in a 4-day cross-country biking challenge. He biked for 48, 51, and 59 miles on the first three days. How many miles does he need to bike on the last day so that his average (mean) is 55 miles per day?
Answer:
62 miles
Step-by-step explanation:
The formula for average is given as
Sum of values / Number of values
Let x = miles on the last day
Hence
48 + 51 + 59 + x/4 = 55
Cross Multiply
= 158 + x = 220
x = 220 - 158
x = 62
Therefore, he needs to bike 62 miles on the last day so that his average (mean) is 55 miles per day.

Step-by-step explanation:
Find the point that partitions segment AB in a 2: 1 ratio.
Please don't give me a link to a file, because it doesn't work for me.
The point that partitions segment AB in a 2: 1 ratio is point (5,19/3).
Suppose the point that partitions segment AB in a 2: 1 ratio is point (x,y)
What is the internal division formula?
The internal division formula for a line segment is given by:
[tex]x=\frac{m_1x_2+m_2x_1}{m_1+m_2}[/tex]
[tex]y=\frac{m_1y_2+m_2y_1}{m_1+m_2}[/tex]
Where (x₁,y₁) and (x₂,y₂) are endpoints of the line segment.
Coordinates of points A≡(1,3)
Coordinates of points B≡(7,8)
[tex]x=\frac{2*7+1*1}{1+2}[/tex]
[tex]x=5[/tex]
Similarly, [tex]y=\frac{19}{3}[/tex]
So (x,y)≡(5,19/3)
Hence, the point that partitions segment AB in a 2: 1 ratio is point (5,19/3).

Fill in the table using this function rule. y=-3x-3
Answer:
When x = -2, y = 3
When x = -1, y = 0
When x = 0, y = -3
When x = 1, y = -6
Step-by-step explanation:
Given:
y = -3x - 3
Fill in the table using the following value for x
When x = -2
y = -3x - 3
y = -3(-2) - 3
y = 6 - 3
y = 3
When x = -2, y = 3
When x = -1
y = -3x - 3
y = -3(-1) - 3
y = 3 - 3
y = 0
When x = -1, y = 0
When x = 0
y = -3x - 3
y = -3(0) - 3
y = 0 - 3
y = -3
When x = 0, y = -3
When x = 1
y = -3x - 3
y = -3(1) - 3
y = -3 - 3
y = -6
When x = 1, y = -6
