Step-by-step explanation:
[tex] \sin(30) = \frac{n}{ \frac{10 \sqrt{3} }{3} } \\ 0.5 = \frac{n}{5.77} \\ n = 2.88 = \frac{5 \sqrt{3} }{3} [/tex]
[tex] \cos(30) = \frac{m}{ \frac{10 \sqrt{3} }{3} } \\ 0.866 = \frac{m}{5.77} \\ m = 5[/tex]

Write a function representing the line that includes the points (3,3) and (-6,15)
A function representing the line that includes the points (3,3) and (-6,15) is 3y=-4x+21.
The given coordinate points are (3,3) and (-6,15).
What is the slope intercept form?The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.
The standard form of the slope intercept form is y=mx+c.
Now, slope=(y2-y1)/(x2-x1)
= (15-3)/(-6-3)
= 12/(-9)
= -4/3
Substitute m=-4/3 and (x, y)=(3, 3) in y=mx+c, we get
3=-4/3 (3) +c
c=7
Put, m=-4/3 and c=7 in y=mx+c, we get
y=-4/3 x+7
3y=-4x+21
Therefore, a function representing the line that includes the points (3,3) and (-6,15) is 3y=-4x+21.

How many non zero digits should numbers written in scientific notation have
Answer:
All the none-zero digits given should be included when written in scientific notation. But also any trailing zeros written after non-zero digits should also be included.
For example in 0.00900 the 900 is significant because the person who included the trailing zeros is saying look I measured this far and these zeros are significant.

In exercises 27-30, three vertices of DEFG are given. Find the coordinates of the remaining vertices: D(-2,-4)
Answer:
[tex]E =[/tex] [tex](-3,3)[/tex]
Step-by-step explanation:
The question has missing parameters.
The (missing) given coordinates are:
[tex]D(x_1,y_1) = (-2,-4)[/tex]
[tex]F(x_3,y_3) = (0,7)[/tex]
[tex]G(x_3,y_4) = (1,0)[/tex]
Required
Find the coordinates of [tex]E(x_2,y_2)[/tex]
To do this, we make use of mid-point formula which is:
[tex]M = (\frac{x_1+x_3}{2},\frac{y_1+y_3}{2})= (\frac{x_2+x_4}{2},\frac{y_2+y_4}{2})[/tex]
This gives:
[tex](\frac{-2+0}{2},\frac{-4+7}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})[/tex]
[tex](\frac{-2}{2},\frac{3}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})[/tex]
Multiply through by 2
[tex]2 * (\frac{-2}{2},\frac{3}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})*2[/tex]
[tex](-2,3) = (x_2+1,y_2+0)[/tex]
[tex](-2,3) = (x_2+1,y_2)[/tex]
By comparison:
[tex]-2 = x_2 + 1[/tex] and [tex]3= y_2[/tex]
So, we have:
[tex]-2-1=x_2[/tex] and [tex]3= y_2[/tex]
[tex]-3 = x_2[/tex] and [tex]3 = y_2[/tex]
This gives:
[tex]x_2 = -3[/tex] and [tex]y_2 =3[/tex]
Hence, the 4th coordinate is: [tex](-3,3)[/tex]
A ladder is 12 metres long . It leans against a wall with one end on the ground 7 metres from the wall. The other end just reaches a windowsill. Calculate the height of the windowsill above the ground.
i need an explanation please...
Answer:
window sill height =9.75 meters
Step-by-step explanation:
Ladder^2=height^2+length^2
12^2=height^2+7^2
144=height^2+49
height^2=144-49=95
height=9.75

Step-by-step explanation:
The question is not complete. But I would solve a similar question.
Solution:
A quadrilateral is a polygon shape with four sides and four angles.
Two polygons are said to be similar if they have the same shape and the ratio of their corresponding sides are equal to each other (that is their corresponding sides are in the same proportion).
Given that Quadrilateral ABCD is similar to quadrilateral GHIJ, hence their corresponding sides are similar.
[tex]\frac{AB}{GH} = \frac{AD}{GJ} \\\\\frac{x}{24} = \frac{4}{12} \\\\x=\frac{4*24}{12}\\\\x=8[/tex]

3. State if each of the labeled points is a local min, max or
neither.
Is the function even or odd? Explain.
Please explain right I’m giving 100 points in this that means the 2 people Who answers this will get 50 each
Answer:
(5, 7) is a local maximumFunction is oddStep-by-step explanation:
As we see on the graph:
point (1,2) on the falling section,point (3,3) on the rising section,point (5,7) on the top section,... of the local intervals. therefore only point (5, 7) is a local maximum.
Absolute minimum is - oo, absolute maximum is + oo
A function is even if its graph is symmetric with respect to the y-axis. A function is odd if its graph is symmetric with respect to the origin.The given function is odd as per above definition

Step-by-step explanation:
There are many ways to solve this equation, but an easy one would be ((4 x 16) ÷ 2) - 8
4 times 16 = 64
64 ÷ 2 = 32
32 - 8 = 24

Answer:
25
Step-by-step explanation:
Formula
[tex]B = 25(\frac{M}{10} +\frac{3}{4} )[/tex]
Where M meters of granola makes B granola bars.
Given:
M = 2.5 meters
Now substitute that value in the formula and calculate.
[tex]B=25(\frac{2.5}{10} +\frac{3}{4} )= 25(1) = 25[/tex]
Therefore, 2.5 meters of granola makes 25 granola bars.
B = 25

A rental car company charges $31 per day to rent a car and $0.13 for every mile
driven. Jocelyn wants to rent a car, knowing that:
She plans to drive 500 miles.
• She has at most $220 to spend.
.
Write and solve an inequality which can be used to determine d, the number of days
Jocelyn can afford to rent while staying within her budget.
Answer:
The number of days is at most 5 days
= d ≤ 5 days
Step-by-step explanation:
A rental car company charges $31 per day to rent a car and $0.13 for every mile driven. Jocelyn wants to rent a car, knowing that:
She plans to drive 500 miles.
• She has at most $220 to spend.
At most means Less than or equal to $220
The inequality for expressing this = ≤
Hence, the inequality which can be used to determine d, the number of days Jocelyn can afford to rent while staying within her budget.
$31 × d + $0.13 × 500 miles ≤ $200
The inequality is given as:
31d + 65 ≤ 220
Solving further
31d ≤ 220 -65
31d ≤ 155
d ≤ 155/31
d ≤ 5
Therefore, the number of days is at most 5 days
