Answer:
C. 5.8
Step-by-step explanation:
We use the Pythagoras theorem here. which is a²+b²=c².
a and b are the replacements for the 5miles and 3miles here.
They are a and b because a and b are always on the right angle side.
The longest side of this triangle is called a hypotenuse which is the c in this case.
the other sides (a and b) are called the adjacent and the opposite.
it doesn't matter if you use adjacent or opposite for a and b in this case.
the only important thing is the hypotenuse here.
So it's a²+b²=c², which is 5²+3²=c².
5² is 25 and 3² is 9, so we add them and we get 34.
so c²=34, we don't want the square on c so we send it to 34 which becomes √34.
√34 gives us 5.8 miles which is up to just only one decimal place.
You might need to use calculators for square roots because they take long to calculate.

Answer:
5000
Step-by-step explanation:
In a right triangle ,
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
[tex] = > c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]
where -
c = hypotenusea & b = the other two sides of the triangleAccording to the question , let the hypotenuse of the triangle be 'c' . So ,
[tex]c = \sqrt{ {3000}^{2} + {4000}^{2} } [/tex]
[tex] = > c = \sqrt{9000000 + 16000000} [/tex]
[tex] = > c = \sqrt{25000000} = 5000[/tex]
Hence , c = 5000
Answer:
5000
Step-by-step explanation:
[tex]3000^{2}[/tex] + [tex]4000^{2}[/tex] = 25000000
[tex]\sqrt{25000000}[/tex] = 5000

column 2, (8 and 4)
Step-by-step explanation:
For the first one, y = 2[tex]x^{2}[/tex]. You would plug in 1 into x and since one times itself is one, you would end up with 2. For the next question, you would plug in one and find that two times one is two. For the next column, by plugging in 2, you would find that you would end up with 2 times 4 and thus, you would find the answer which is 8. Lastly, two to the power of two is 4. Hope this helped!

To distinguish it from other exponential functions, the exponential function f(x)=e^x is frequently referred to as the natural exponential function.
What is exponential function?The mathematical symbol again for exponential function is e^x. The word, unless specifically stated differently, typically refers to the optimistic functional of a real variable, but it may be extended towards the complex numbers or adapted to other mathematical like matrices and Lie algebras.
The idea of exponentiation, or repeated multiplication, is where the exponential function got its start, but more recent definitions—there are several that are equivalent—allow for it to be rigorously expanded to everyone real arguments, especially irrational values.
A. FX) = 2 (7)→ 6(a+8)
O B. FX) = 2→4(1+ 9x)
C. F(X) = 2 · (0.5)→(9m + 10) x 2
D. FX) = 2(16)→ 3 (2x + 4y - 15z)
Therefore, to distinguish it from other exponential functions, the exponential function f(x)=e^x is frequently referred to as the natural exponential function.

FIND TWO NUMBERS WHOSE SUM IS 21 AND DIFFERENCE IS 17
11 , 10
2 ,23
19 ,2
Answers
Answer:
19, 2
Step-by-step explanation:
let the 2 numbers be x and y with x > y , then
x + y = 21 → (1)
x - y = 17 → (2)
Add the 2 equations term by term to eliminate y , that is
2x = 38 ( divide both sides by 2 )
x = 19
substitute x = 19 into (1) for value of y
19 + y = 21 ( subtract 19 from both sides )
y = 2
The 2 numbers are 19 and 2

If a triangle has 2 sides of 8 and 11 what could the third side be
Answers
Answer:
Any value between 3 and 19 may be the measure of third side.
Step-by-step explanation:
If three sides of a triangle are a, b, and c, possible measures of the sides of a triangle will be.
1). a + b > c
2). b + c > a
3). a + c > b
If a = 8, b = 11,
1). 8 + 11 > c
c < 19
2). 11 + c > 8
c > 8 - 11
c > (-3)
3). 8 + c > 11
c > 11 - 8
c > 3
Therefore, by combining the given inequalities,
3 < c < 19
Any value between 3 and 19 may be the measure of third side.
Can someone help me with this please
Answers
Answer:
Step-by-step explanation:
4) the first thing to notice is that the sides a and c are the same.. that's what the small marks are telling you... that are the same length. and since they are.. this is an isosceles triangle and the two angle at the base .. along the b side will be the same.. so solving y is just the same as A or 52°
then to solve for x we also need to use that the triangle add up to 180° on those inside angles..
180= 52+52+14x+6
maybe you can solve it from here.. but i'll do it quickly
70 = 14x
5=x
5) the exterior angle at C is 146 the total angle is 180 so the angle inside the triangle is 180=146+x x= 34°
then use that the interior of the triangle add up to 180 again
180 = 34 + 5y+3 + 4y + 8
180 = 45 +9y
135 =9y
15 = y

ΔABC is similar to ΔFED. Answer the questions to find the length of DF .
1. Which side in ΔFED does AB in ΔABC correspond to?
Write your answer in the space below.
2. Which side in ΔFED does CB in ΔABC correspond to?
Answers
Answer:
1.AB are the first 2 letters in ΔABC. Similarly, FE are the first 2 letters in ΔFED.
Hence side AB corresponds to side FE.
2.CB are the last 2 letters in ΔABC. Similarly, DE are the last 2 letters in ΔFED.
3.AC corresponds to FD
4.The scale factor is 2 because you would take the sides in ABC and multiply by 2 to get the sides in FED
5.6 because it corresponds to CB and you would multiply the side of CB (3) by 2 and you would get 6
6.A^2+B^2=C^2 = FE^2+ED^2=FD^2 = 8^2+6^2=100^2 = square root of 100= 10
The side length of FD is 10
