Use similar triangles and a proportion to find the length of the lake shown here.
(Hint: The side 92 m long in the smaller triangle corresponds to side of 92 m + 112 m = 204 m in the larger triangle.)
N= m
Answers
Answer: n = 152 m
Step-by-step explanation:
write a proportion to find n.
46/n = 92/204
n = 102 m
The length of the lake shown in the provided image using similar triangles and a proportion is 102 meters.
What is similar triangle's proportion property?In the two similar triangle, the ratio of two sides of one triangle is equal to the ratio of corresponding sides of the other triangle.
In the figure shown,
The length of the base of the smaller triangle is 92 meters, The height of this triangle is 46 meters.The total length of the base of the larger triangle is,
[tex]112+92=204\rm\; m[/tex]
The height of this triangle is n meters, which is equal to the length of lack. Thus, by the similar triangle proportion property,
[tex]\dfrac{n}{204}=\dfrac{46}{92}\\n=\dfrac{46\times204}{92}\\n=120\rm\; meters[/tex]
Thus, the length of the lake shown in the provided image using similar triangles and a proportion is 102 meters.

what is the area of the rectangle whose length is (x + 5) and width (x-5)
Answers
Answer:
area of the rectangle is length *breadth
length =(x+5)
breadth =(x-5)
=(x+5)(x-5)=x^2-5x+5x-25=x^2-25
Answer:
[tex]\boxed {\boxed {\sf a=x^2-25}}[/tex]
Step-by-step explanation:
The area of a rectangle is the product of length and width.
[tex]a=l*w[/tex]
The length is (x+5) and the width is (x-5).
[tex]a= (x+5)(x-5)[/tex]
We have two binominals, so we can multiply using FOIL: First, Outside, Inside, Last.
F: x*x= x²O: x*-5= -5x I: x*5= 5x L: 5*-5 = -25[tex]a= x^2-5x+5x-25[/tex]
Combine the like terms: -5x and 5x. They cancel each other out.
[tex]a=x^2-25[/tex]
The area of the rectangle is x²-25

A fair 10 sided die rolled until a 7 is first seen. What is the probability of rolling the die six times?
Answers
Answer:
The probability of rolling a dice six time until a 7 is first seen is 0.059
Step-by-step explanation:
The probability of getting a seven is equal to [tex]\frac{1}{10}[/tex]
The dice need to be rolled only six times.
This means that for the first 5 times the dice showed values other than 7 and in the last roll it displays 7
Hence the probability of rolling a dice six time until a 7 is first seen is
[tex](\frac{9}{10})^5 * (\frac{1}{10})^1[/tex]
[tex]= \frac{9^5}{10^6} \\= 5.90[/tex] % or 0.059

What is the sixth number in the Fibonacci sequence with the first two numbers 1 and 4?
Answers
Answer:
23
Step-by-step explanation:
1 + 4 = 5 so we get 1 4 5
then 4+5 = 9, 1 4 5 9
5+9 = 14, 1 4 5 9 14
9+14 = 23, so
1 4 5 9 14 23
23 is the 6th number in this sequence
The sixth number in the Fibonacci sequence with the first two numbers 1 and 4 is 23 and this can be determined by using the arithmetic operations.
Given :
Fibonacci sequence with the first two numbers 1 and 4.
The following steps can be used to determine the sixth number in the Fibonacci sequence:
Step 1 - If the first two numbers in the Fibonacci sequence is 1 and 4 then the third number is:
= 1 + 4
= 5
Step 2 - The Fourth number in the Fibonacci sequence is:
= 4 + 5
= 9
Step 3 - The Fifth number in the Fibonacci sequence is:
= 5 + 9
= 14
Step 4 - The Sixth number in the Fibonacci sequence is:
= 9 + 14
= 23
So, the sixth number in the Fibonacci sequence with the first two numbers 1 and 4 is 23.

Given the definitions of f (x) and g(x) below, find the value of (gof)(-8).
f(x) = -x + 8
g(x) = x2 – 3x+2
Answers
Answer:
(gof)(-8) = 210
Step-by-step explanation:
(gof) = (-x + 8)² - 3(-x + 8) = 2
= x² - 16x + 64 + 3x - 24 + 2
= x² - 13x + 42
(gof)(-8) = (-8)² - 13(-8) + 42
= 64 + 104 + 42

Given a quadratic equation, how can you determine whether the parabola opens up or down?
Answers
By whether x^2 has a negative or positive coefficient.
If the parabola opens down, x^2 has a negative sign in front of it.
If the parabola opens up, x^2 does not have a negative.
Explanation:
Completely expand a quadratic equation into this polynomial form to find “a”:
ax^2 + bx + c
When “a” is positive, the parabola opens up.
When “a” is negative, the parabola opens down.
