Answer: In the figure AB is about 8.4 inches and AC is about 13.05 inches.
Step-by-step explanation: We can use cosine to find the hypotenuse. [tex]cos(40)=\frac{10}{x} \\cos(40) (x)=\frac{10}{x}(x)\\cos(40) (x) =10\\\frac{cos(40) (x)}{cos (40)} =\frac{10}{cos (40)} \\x=\frac{10}{cos(40)}[/tex]
Using a calculator x is about 13.05
Using tangent we can find the length opposite of <C
[tex]tan(40)=\frac{x}{10} \\tan(40) (10)=\frac{x}{10}(10)\\tan(40) (10) = x[/tex]
Using a calculator x would be about 8.4

Hi, does anyone know the answer to this question? I’m bad at geometry and I’m struggling to answer it.
What is the difference between the ordinates of the points ( -2 , 3 ) and ( 5, 8 ) ?
Answer:
the difference in the coordinate points is (7, 5)
Step-by-step explanation:
Given;
first coordinate point, (x₁, y₁) = (-2, 3)
second coordinate point, (x₂, y₂) = (5, 8)
The difference in the coordinate points is calculated as follows;
Δ(x, y) = (x₂ - x₁, y₂ - y₁)
= (5 - -2, 8 - 3)
= (7, 5)
Therefore, the difference in the coordinate points is (7, 5)

If cos theta = 0.8, find 1 / sin (pi/2 - theta)
Answer:
J
Step-by-step explanation:
Using the cofunction identity
cosθ = sin([tex]\frac{\pi }{2}[/tex] - θ )
Then
[tex]\frac{1}{sin(\frac{\pi }{2}-0) }[/tex]
= [tex]\frac{1}{cos0}[/tex]
= [tex]\frac{1}{0.8}[/tex]
= 1.25 → J
The value of 1/sin([tex]\frac{\pi }{2}[/tex] - θ) is 1.25.
What are four quadrants of trigonometry?The coordinate axes divide the plane into four quadrants, labelled first, second, third and fourth as shown. Angles in the third quadrant, for example, lie between 180 degrees and 270 degrees.
Given
1/cosθ = 0.8
1/sin([tex]\frac{\pi }{2}[/tex] - θ) =?
By using quadrants in trigonometry
we know that sin([tex]\frac{\pi }{2}[/tex] - θ) = cosθ
= 1/sin([tex]\frac{\pi }{2}[/tex] - θ)
= 1/cosθ
= 1/0.8
= 1.25
1/sin([tex]\frac{\pi }{2}[/tex] - θ) = 1.25
Hence, the value of 1/sin([tex]\frac{\pi }{2}[/tex] - θ) is 1.25.

A.
rectangle
B.
square
C.
trapezoid
D.
rhombus
Answer: C) Trapezoid
Refer to the figure below. Note how sides BC and AD are parallel. We have exactly one pair of parallel sides, so that's why we have a trapezoid.
The figure with the vertices (0,0), (-1, 1), (6, 1), and (2, 0) is a trapezoid
What is a trapezoid?The Trapezoid is a 4 sided polygon. Two sides of the shape are parallel to each other and they are termed as the bases of the trapezoid. The non-parallel sides are known as the legs or lateral sides of a trapezoid.
There are three types of trapezoids , and those are given below:
a) Isosceles Trapezoid
b) Scalene Trapezoid
c) Right Trapezoid
The area of the Trapezoid is given by
Area of Trapezoid = ( ( a + b ) h ) / 2
where , a = shorter base of trapezium
b = longer base of trapezium
h = height of trapezium
Given data ,
Let the coordinates of the figure be represented as ABCD
Now , the vertices of the figure is
A ( 0 , 0 ) , B ( -1 , 1 ) , C ( 6 , 1 ) and D ( 2 , 0 )
On plotting the coordinates in the graph , we get a trapezoid with
The longer base = BC
The shorter base = AD
So , the figure is a trapezoid
Hence , the vertices represents a trapezoid

The tennis courts are 3 blocks west and 2 blocks south of Miguel’s house. The bike path is 5 blocks east and 2 blocks south of Miguel’s house. How many blocks are the tennis courts from the bike path?
Answer:
8
Step-by-step explanation:
If Miguel's house is (0,0), then the tennis court is (-3,-2), and the bike path is (5,-2). There fore, we can just count the squares between the tennis court and the bike path, which is 8.
Hope that this helps!
From the coordinate calculation, here tennis courts are 8 blocks far from the bike path.
Given that,
The tennis courts are 3 blocks west and 2 blocks south of Miguel’s house. The bike path is 5 blocks east and 2 blocks south of Miguel’s house. How many blocks are the tennis courts from the bike path is to be detemined.
Coordinate, is represented as the values on the x-axis and the y-axis of the graph.
Here on the graph,
Assume that Miguel's house is (0,0),
then accoding to the question the tennis court is (-3,-2), and the bike path is (5,-2).
Now, difference in the position dx = 5 - (-3)
= 8
Thus, from the coordinate calculation, here tennis courts are 8 blocks far from the bike path.

Marc is building a rectangular wooden frame for his canvas. If the canvas is 7 feet long by 5 feet wide, what is the perimeter of the canvas?
Answer:
24 feet
Step-by-step explanation:
Use the perimeter formula, P = 2l + 2w, where l is the length and w is the width.
Plug in the values, and solve:
P = 2l + 2w
P = 2(7) + 2(5)
P = 14 + 10
P = 24
So, the perimeter of the canvas is 24 feet

Homework June 10th 2021 Jim
Problem 1
Part (a)
It is possible to find the equation of the line of best fit by hand, but it's much more efficient to use technology. That could mean a graphing calculator, an online tool, or some computer software installed. I'm going to use GeoGebra. Specifically, I'm using the "FitLine" command to find the regression line.
The equation of line of best fit is y = -2.45x + 11.83
There's not much to say in terms of steps, since it's basically a calculator problem. Doing this by hand would take a lot longer than it should be.
------------
Part (b)
Plug in x = 2.3 and evaluate
y = -2.45x + 11.83
y = -2.45*2.3 + 11.83
y = 6.195
Answer: 6.195
-------------
Part (c)
We'll compare the result from the previous part (6.195) to the y value in the table (6.2)
The difference is 6.2 - 6.195 = 0.005
This means the estimated value is off by 0.005 and this is an underestimate (since 6.195 is smaller than 6.2)
===================================================
Problem 2
To be perfectly honest, I'm not sure what's going on here. It seems like there's missing context to the problem. Perhaps a data table that got cut off or this is referring to a previous problem.
===================================================
Problem 3
Recall that y = mx+b is the slope intercept form
m = slope
b = y intercept
We simply read off the values of the given equation y = 0.404x - 5.18 to see that 0.404 is the slope and -5.18 is the y intercept
The slope tells us that each time x goes up by 1, y will increase by an estimated amount of 0.404; this represents the unit rate or speed. In this context, it means the height goes up by about 0.404 cm per day. This is an estimated value because the regression line itself is a collection of estimated points.
The y intercept is where the graph crosses the y axis. It always occurs when x = 0. The x refers to the day number. Day 0 is basically the starting day. So the y intercept being -5.18 means the estimated height is -5.18 cm on the starting day. At first glance, it might not seem possible to have a negative height. But simply think of negative heights as below ground level, much like how the negative y values are below the x axis.
In other words, the plant is estimated to start off at about 5.18 cm below ground level. This is a reasonable assumption because the seed is buried into the ground (assuming at this level more or less) and it then grows upward.

Point G is located at (6, 2) on the coordinate plane. Point G is reflected over the y -axis to create point G^ prime . What ordered pair describes the location of G?
Answer:
The ordered pair that best describes the location of G' is (-6,2).
Step-by-step explanation:
Reflecting a point over the y-axis:
When a point (x,y) is reflected over the y-axis, it's x coordinate is multiplied by -1, while the y-coordinate stays the same. Thus:
(x,y) -> (-x,y).
Point G is located at (6, 2)
When reflected over the y-axis:
G'(-6,2).
The ordered pair that best describes the location of G' is (-6,2).
