To measure the distance across a pond, a surveyor locates points A, B, C, D, and E as shown. Find the length of AB to the nearest meter. Explain how you got this answer.
Answer:
formula with a squared term.
It’s not about distance in the sense of walking diagonally across a room. It’s about any distance, like the “distance” between our movie preferences or colors.
If it can be measured, it can be compared with the Pythagorean Theorem. Let’s see why.
Understanding The Theorem
We agree the theorem works. In any right triangle:
pythagorean theorem
If a=3 and b=4, then c=5. Easy, right?
Well, a key observation is that a and b are at right angles (notice the little red box). Movement in one direction has no impact on the other.
It’s a bit like North/South vs. East/West. Moving North does not change your East/West direction, and vice-versa — the directions are independent (the geek term is orthogonal).
The Pythagorean Theorem lets you use find the shortest path distance between orthogonal directions. So it’s not really about right triangles — it’s about comparing “things” moving at right angles.
You: If I walk 3 blocks East and 4 blocks North, how far am I from my starting point?
Me: 5 blocks, as the crow flies. Be sure to bring adequate provisions for your journey.
You: Uh, ok.
So what is “c”?
Well, we could think of c as just a number, but that keeps us in boring triangle-land. I like to think of c as a combination of a and b.
But it’s not a simple combination like addition — after all, c doesn’t equal a + b. It’s more a combination of components — the Pythagorean theorem lets us combine orthogonal components in a manner similar to addition. And there’s the magic.
In our example, C is 5 blocks of “distance”. But it’s more than that: it contains a combination of 3 blocks East and 4 blocks North. Moving along C means you go East and North at the same time. Neat way to think about it, eh?
From the picture attached,
AB and ED are the parallel sides of two triangles ΔCDE and ΔCBA.Measure of sidesDE = 5 m, CD = 5 m, CE = 4 m and CA = 12 m
In ΔCDE and ΔCBA,
Two sides AB and ED are parallel and two lines AC and BC are intersecting these lines,
Therefore, ∠CDE ≅ ∠CBA and ∠CED ≅ ∠CAB [Corresponding angles]
By AA postulate of similarity,
ΔCDE ~ ΔCBA.
By using the property of two similar triangles,
"Corresponding sides of two similar triangles are proportional"
[tex]\frac{CE}{CA}= \frac{DE}{BA}[/tex]
[tex]\frac{4}{12}= \frac{5}{AB}[/tex]
[tex]AB=\frac{5\times 12}{4}[/tex]
[tex]AB=15[/tex] m
Therefore, length of AB will be 15 meters.

Television sizes are determined by the length of their diagonal measure. Michael just bought a new television. The height of the television is 37 inches and the length is 71 inches.
Using the Pythagorean Theorem, what is the size of Michael’s new television? Round your answer to the nearest whole inch (whole number).
Part A: What parts of the right triangle have you been given? Are you looking for a leg or the hypotenuse?
Part B: Set-up your equation by substituting the correct numbers into the Pythagorean Theorem formula.
Part C: Solve for the missing length rounded to the nearest whole number. Remember to show ALL work for each step.
Part D: What is the size of the television rounded to the nearest whole inch (whole number)? REMEMBER: We’re looking for the length of the diagonal, as that is the measurement used to determine TV Sizes.
Answer:
Part A we are given the legs and are looking for the hypotenuse
Part B 37^2 + 71^2 = c^2
Part C 37^2 + 71^2 = c^2
961+5041 = c^2
6002 = c^2
Take the square root of each side
sqrt(6002) = sqrt(c^2)
77.47257579=c
c = 77
Part D The size is 77 inches
Step-by-step explanation:
The pythagorean theorem is a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
a = 37 and b = 71 were are looking for the diagonal ( or hypotenuse) which is the size
37^2 + 71^2 = c^2
961+5041 = c^2
6002 = c^2
Take the square root of each side
sqrt(6002) = sqrt(c^2)
77.47257579=c
Rounded to the nearest whole number
77 =c
The size is 77 inches
Solve for G
9+3.5g=11-0.5g
G=_______
Answer:
g = 1/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
9+3.5g=11−0.5g
9+3.5g=11+−0.5g
3.5g+9=−0.5g+11
Step 2: Add 0.5g to both sides.
3.5g+9+0.5g=−0.5g+11+0.5g
4g+9=11
Step 3: Subtract 9 from both sides.
4g+9−9=11−9
4g=2
Step 4: Divide both sides by 4.
g= 1/2

Answer: these are in "slope-intercept form" y = mx + b
m is the slope. b is the y-intercept
Start with the y- intercept, the "constant" on the right side of the equation. Plot a point there on the y-axis. Then use the slope to plot another point or two to find our where to draw the line. If there is no number for m, it is an implied 1. That means from your first point, go up 1 then 1 to the right to plot the next point
Step-by-step explanation:
When the slope is a fraction, use the denominator to find out how far to go to the right.
If the slope is negative, move down first then to the right to plot the next point.

Answer:
you would take your index finger and your thumb and put them toward the eraser and move your fingers and the answer is 9 or 13 if you needed help with that
Step-by-step explanation:
Answer:
13 cm
Step-by-step explanation:
The good news is that you don't need a ruler!
First, you see that the eraser is approximately 5 cm in length, so you must your mind to mentally picture the eraser beside it. You end up with 10 cm. Then, you see that there is more space left on the stick. You know that another complete eraser will not fill up that space. So, you must ask yourself: What is larger than 9 cm, but smaller than 15 cm? The answer is 13 cm!

1) 7= 1+ 2p 2) -3p + 5= 8
Answer:
p=3 and p=-1
Step-by-step explanation:
1) 7=1+2p
Subtract 1 on both sides to isolate x.
7=1+2p
-1 -1
6=2p
Divide both sides by 2.
6=2p
/2 /2
3=p
2) -3p+5=8
Subtract 5 on both sides to isolate x.
-3p+5=8
-5 -5
-3p=3
Divide both sides by -3.
-3p=3
/-3 /-3
p=-1
