f(g(x)) = 2/(x^2 +4x)
Step-by-step explanation:

A sling is in the shape of an isosceles triangle with a perimeter of 155 inches. The longest side of the sling is 14 inches longer than either of the other two sides. Find the lengths of each side.
Hello there.
To answer this question, we need to remember some properties of the isosceles triangle.
First (and most importantly), an isosceles triangle is composed by three sides, in which only two of the sides have equal length.
The perimeter of a triangle is given by the sum of the lengths of the sides, such that: [tex]2p={\ell}_1+{\ell}_2+{\ell}_3[/tex], in which [tex]p[/tex] is the semiperimeter.
Given that the perimeter of such triangle is equal to [tex]155~\text{in}[/tex] and the longest side is [tex]14~\text{in}[/tex] longer than both the other sides, we have that:
[tex]\begin{cases}{\ell}_2={\ell}_3\\ {\ell}_1+{\ell}_2+{\ell}_3=155\\ {\ell}_1={\ell}_2+14\\\end{cases}[/tex]
Using these informations, in terms of [tex]{\ell}_2[/tex], we get:
[tex]{\ell}_2+14+{\ell}_2+{\ell}_2=155[/tex]
Sum the equal terms on the left hand side of the equation
[tex]3\,{\ell}_2+14=155[/tex]
Subtract [tex]14[/tex] on both sides of the equation
[tex]3\,{\ell}_2=141[/tex]
Divide both sides of the equation by a factor of [tex]3[/tex]
[tex]{\ell}_2=47~\text{in}[/tex]
Substituting this value on the first and second equations, we get:
[tex]{\ell}_3=47~\text{in}\\\\\\ {\ell}_1=47+14=61~\text{in}[/tex]
Thus, the length of the sides of this triangle are, respectively from the largest to the smallest: [tex]{\ell}_1=61~\text{in},~{\ell}_2=47~\text{in},~{\ell}_3=47~\text{in}~~\checkmark[/tex]
These are the values we were searching for.

A bakery sells 7 cakes each day.
A different bakery sells 9 cakes
each day. What is the total
number of cakes the bakeries
sold after 7 days?
Answer:
112 cakes
Step-by-step explanation:
7×7=49
9×7=63
49+63=112
[tex]\text{Hello there!}[/tex]
First, we will need to find out how much each of the bakeries accrued within 7 days. We should be able to do this by simply multiplying the amount of cakes the bakery sells each day by the amount of days it's been accruing it for.
For example:
[tex]\text{7}[/tex] • [tex]\text{7}[/tex] = [tex]\text{49}[/tex]
[tex]\text{9}[/tex] • [tex]\text{7}[/tex] = [tex]\text{63}[/tex]
Since the answer doesn't explain if you're giving EACH of the bakeries amounts or combining them, that's up to you to decide if you want to do that or not.
1. Which statement is correct for 450-450-90° triangles?
A. hypotenuse = V3 • leg
B. hypotenuse • V2 = leg
C. hypotenuse=v2 • leg
D. hypotenuse divided V3 = leg
Answer: 3rd answer is the correct answer.
Applying the Pythagorean theorem, we find that the length of the hypotenuse is equal to the square root of 2. In other words, the hypotenuse is root 2 times the length of either leg.

if 100 kids = 40%, how many kids =100%
Answer:
The answer is 250 kids
Step-by-step explanation:
Please give me brainlest
Answer:
250
Step-by-step explanation:
If 100 kids is 40%, then 200 kids (twice as much) is 80%. 20% (what's remaining) is half of 40%, so it is also half of 100; 50. Add that together, 250 kids.

Let the graph of g be a translation 2 units left and 3 units up, followed by a reflection in the y-axis of the graph of f(1) = ? - 24 Write a rule for g.
Answer:
g(x) = (x+2)^2 - 2x - 1
Step-by-step explanation:
f(x) = x^2 - 2x
g(x) = f(x+2) + 3
g(x) = (x+2)^2 -2(x+2) + 3 = (x+2)^2 - 2x - 1
When we graph the equations, we can confirm that our answer is correct.
The required solution of the given function is f(x) =[tex]x^{2} -2x[/tex] is reflection on y axis is [tex]g(x)= (x+2)^2 - 2x - 1[/tex].
What are transformations?
A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
Given:
The given function is
f(x) =[tex]x^{2} -2x[/tex]
According to given question we have
[tex]g(x) = (x+2)^2 - 2x - 1[/tex]
The graph of g be a translation 2 units left and 3 units up, followed by a reflection in the y-axis of the graph.
By the use reflection on y axis we get
[tex]f(x) = x^2 - 2x\\g(x) = f(x+2) + 3\\g(x) = (x+2)^2 -2(x+2) + 3\\ \\g(x)= (x+2)^2 - 2x - 1[/tex]
Therefore, the required solution of the given function is f(x) =[tex]x^{2} -2x[/tex] is reflection on y axis is [tex]g(x)= (x+2)^2 - 2x - 1[/tex].

Factoring: 25x2 - 4
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A² - AB + BA - B² =
A² - AB + AB - B² =
A² - B²
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 4 is the square of 2
Check : x2 is the square of x1

The rule says : To multiply exponential expressions which have the same base, add up their exponents.
In our case, the common base is (x+3) and the exponents are :
1 , as (x+3) is the same number as (x+3)1
and 1 , as (x+3) is the same number as (x+3)1
The product is therefore, (x+3)¹ = (x+3)²

Find f (-61) and f (128)
Step-by-step explanation:
f(x) = ³√(x - 3)
f(-61) = ³√(-61 - 3)
f(-61) = ³√-64
f(-61) = -4
f(128) = ³√(128 - 3)
f(128) = ³√125

The number of times we would spin a number divisible by 3 is 12.
What is the probability?
Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that;
Number of spins= 40
Now,
To predict how many times you would spin a number divisible by 3 in 40 spins, you can multiply the probability of spinning such a number by the number of spins. The probability of spinning a number divisible by 3 is 3/10, as there are 3 numbers out of 10 that are divisible by 3 (3, 6, and 9). the prediction is:
(3/10) x 40 = 120/10 = 12
You would expect to spin a number divisible by 3 about 12 times in 40 spins.
Therefore, by the given data the probability will be 12.

An orchard has 551 orange trees. The number of rows exceeds the number of trees per row by 10. How many trees are there in each row?
Answer:
Step-by-step explanation:
the number of rows = n
The number of trees per row = n + 10
n * (n + 10) = 551 Remove the brackets
n^2 + 10n = 551 Subtract 551 from both sides
n^2 + 10n - 551 = 0 This factors.
(n - 19)(n + 29) = 0
Note n + 29 is an extraneous (extra) root which does not work
n - 19 = 0
n = 19
There are 19 rows
Each row contains 19 trees.
