Can the sides of a triangle have lengths 8.6, 6.6, and 3.3?
yes
no
Answer:
Yes
Step-by-step explanation:
The Triangle Inequality Theorem states that the sum of the lengths of any 2 sides of a triangle must exceed the length of the third side.
8.6+6.6>3.3 is true
6.6+3.3>8.6 is true
3.3+8.6>6.6 is true
As a part of their weather unit, Anoki’s science class took a hot air balloon ride. As they passed over a fenced field, the angle of depression of the closer side of the fence was 32°, and the angle of depression of the farther side of the fence was 27°. If the height of the balloon was 800 feet, estimate the width of the field. Round your answer to the nearest foot.
Hello there!
I hope you and your family are staying safe and healthy!
P.S. I did my best drawing the problem :)
[tex]Tan 32 = \frac{800}{x}[/tex]
[tex]x = \frac{800}{tan32}[/tex]
[tex]Tan 27 = \frac{800}{y}[/tex]
[tex]y=\frac{800}{tan27}[/tex]
Answer: ~289.8 ft

Which of the coordinate pairs is a point on the line y = -2/5x + 4?
A.) (2, 3)
B.) (-5, 6)
C.) (6, 2)
D.) (-2/5, 4)
Answer:
B.) (-5, 6)
Step-by-step explanation:
to solve algebraically, test the coordinate pairs in the equation [tex]y = -\frac{2}{5}x + 4[/tex]
to solve graphically, enter the equation [tex]y = -\frac{2}{5}x + 4[/tex] into a graphing calculator and graph the coordinate pairs as well to see which one is on the line.
(2, 3) is NOT a solution.
steps for solving algebraically:
first, identify the x and y values in your coordinate pair.
2 is the x-value and 3 is the y-value. coordinate pairs are always written as (x, y).plug in 2 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)
y = -2/5x + 4 ⇒ y = -2/5(2) + 4now plug in 3 for y.
y = -2/5(2) + 4 ⇒ 3 = -2/5(2) + 4your equation is now 3 = -2/5(2) + 4. begin simplifying by multiplying -2/5 and 2.
3 = -2/5(2) + 4 ⇒ 3 = -0.8 + 4 (i converted my answer to a decimal because i'm better at dealing with decimals as opposed to fractions lol)now add -0.8 + 4 to simplify the rest of the right side of the equation.
3 = -0.8 + 4 ⇒ 3 = 3.23 and 3.2 are not equal, therefore (2, 3) is not a solution.
(-5, 6) IS a solution.
steps for solving algebraically:
first, identify the x and y values in your coordinate pair.
-5 is the x-value and 6 is the y-value. coordinate pairs are always written as (x, y).plug in -5 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)
y = -2/5x + 4 ⇒ y = -2/5(-5) + 4now plug in 6 for y.
y = -2/5(-5) + 4 ⇒ 6 = -2/5(-5) + 4your equation is now 6 = -2/5(-5) + 4. begin simplifying by multiplying -2/5 and -5.
6 = -2/5(-5) + 4 ⇒ 6 = 2 + 4now add 2 + 4 to simplify the rest of the right side of the equation.
6 = 2 + 4 ⇒ 6 = 66 and 6 are equal, therefore (-5, 6) is a solution.
although we have identified (-5, 6) as a solution, i'm still going to check the rest of the points just to be sure! :)
(6, 2) is NOT a solution.
steps for solving algebraically:
first, identify the x and y values in your coordinate pair.
6 is the x-value and 2 is the y-value. coordinate pairs are always written as (x, y).plug in 6 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)
y = -2/5x + 4 ⇒ y = -2/5(6) + 4now plug in 2 for y.
y = -2/5(2) + 4 ⇒ 2 = -2/5(2) + 4your equation is now 2 = -2/5(6) + 4. begin simplifying by multiplying -2/5 and 6.
2 = -2/5(6) + 4 ⇒ 2 = -2.4 + 4 (i converted my answer to a decimal because i'm better at dealing with decimals as opposed to fractions lol)now add -2.4 + 4 to simplify the rest of the right side of the equation.
2 = -2.4 + 4 ⇒ 2 = 1.62 and 1.6 are not equal, therefore (6, 2) is not a solution.
(-2/5, 4) is NOT a solution.
i see that they want to trick you with this one by using the values that are in other spots in the equation... that's crafty
steps for solving algebraically:
first, identify the x and y values in your coordinate pair.
-2/5 is the x-value and 4 is the y-value. coordinate pairs are always written as (x, y).plug in -2/5 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)
y = -2/5x + 4 ⇒ y = -2/5(-2/5) + 4now plug in 4 for y.
y = -2/5(-2/5) + 4 ⇒ 4 = -2/5(-2/5) + 4your equation is now 4 = -2/5(-2/5) + 4. begin simplifying by multiplying -2/5 and -2/5.
4 = -2/5(-2/5) + 4 ⇒ 4 = 0.16 + 4 (i converted my answer to a decimal because i'm better at dealing with decimals as opposed to fractions lol)now add 0.16 + 4 to simplify the rest of the right side of the equation.
4 = 0.16 + 4 ⇒ 4 = 4.164 and 4.16 are not equal, therefore (-2/5, 4) is not a solution.
as for finding the solution on a graph, enter the equation for the line as well as the coordinate pairs into a graphing calculator. here i used a handy little site called desmos in order to graph all of this. the first photo i attached contains what i entered into the calculator, and the second photo i attached shows the graph. as you can see, the only point that is actually on the line is (-5, 6), which is why (-5, 6) is a solution to [tex]y = -\frac{2}{5}x + 4[/tex] , and the other coordinate pairs are not solutions to that equation because they are not on the line.
i hope this helps! have a lovely rest of your day <3

find the coordinates of the midpoint of AB given A (2,3) and B (4, -2)
Answer:
(3, 1/2)
Step-by-step explanation:
The x-coordinate of the midpoint of AB is the arithmetic mean of 2 and 4, which comes out to 3. The y-coordinate of the midpoint of AB is the arithmetic mean of 3 and -2, which comes out to 1/2.
Thus the midpoint of AB is (3, 1/2).

Given constants a and b such that x2 + ax + b has factors (x + 7) and (x + 2) what is a?
Answer:
a=9 , b=14
Step-by-step explanation:
Just do the operation (x+7)(x+2)
x(x)+x(2)+7(x)+7(2)
x^2+2x+7x+14
x^2+9x+14
So a=9 and b=14
The graph below shows a transformation of the shaded rectangle onto the unshaded rectangle. On a coordinate plane, a shaded rectangle is larger than the unshaded rectangle. Keesha says the transformation is a translation, but Teagan says that the transformation is a dilation. Which statement about the transformation is true? Keesha is correct because the shaded rectangle is moved vertically to make the unshaded rectangle. Keesha is correct because the shaded rectangle is flipped across a horizontal line. Teagan is correct because the unshaded rectangle is smaller than the shaded rectangle. Teagan is correct because the unshaded rectangle is turned in a clockwise direction.
Answer:
C.) Teagan is correct because the unshaded rectangle is smaller than the shaded rectangle.
Step-by-step explanation:
Teagan is correct because the unshaded rectangle is smaller than the shaded rectangle.
What is a Shaded area in a graph?In a graph showing an inequality system, shading above and below denote larger than and less than, respectively. The region's boundary should also be taken into consideration; a solid line denotes equality, while a dashed line denotes non-equality.
In geometry, a function known as translation is one that simply moves an object a predetermined distance without changing it in any way. The object must be moved with each point traveling the same distance and in the same direction. While dilation is a transformation that results in a smaller version of the original thing. A scale factor and a set location in the plane known as the center of the dilatation are needed.
So, when comparing the two shapes, dilation is the transformation. Because the unshaded rectangle is smaller than the shaded area, Teagan is correct.

Answer:
Lucas
Step-by-step explanation:
Katie's response would mean that no matter how many ants there are, there will only always be 6 legs, which is incorrect.
Lucas's response would mean that the number of ants would equal the total number of legs divided by 6, which is correct.

Answer:
f(0)=9
Step-by-step explanation:
All you do is plug in x=0 into the function.
In this case:
f(x)=10^x+8
f(0)=10^0+8
f(0)=1+8
f(0)=9
Therefore, f(0)=9
Answer:
9
Step-by-step explanation:
You put 0 for x
10^0=1, so 1 +8 is 9

is this a function or not
Answer:
No, I don't think so.
Step-by-step explanation:
I don't think this is a function because the triangle is made of multiple points. Some of these points share the same x point, so this concludes that a triangle on a graph is not a function.
