Answer: y=32/x^2
Step-by-step explanation: Please mark brainilest. Since y and x^2 are inversely proportional, x^2(y)=k. K is some constant. Since they gave us an example of x and y, we can calculate k as 4*8=32. So our updated equation is y(x^2)=32. Dividing both sides by x^2 we get y=32/x^2, so we have y in terms of x
Answer:
y = 32x
Step-by-step explanation:
y = k/x^2
8 = k/2^2
8 = k/4
8×4 = 32
k = 32
y = 32x

factorise the expression (a+b)^2=4
The factored expression of the expression given as (a + b)^2 = 4 is (a + b + 2)(a + b - 2) = 0
What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
How to factor the expression?The expression is given as
(a + b)^2 = 4
Express 4 as 2^2
So, we have
(a + b)^2 = 2^2
Rewrite as
(a + b)^2 - 2^2 = 0
Apply the difference of two squares
So, we have
(a + b + 2)(a + b - 2) = 0
Hence, the equivalent expression of the expression given as (a + b)^2 = 4 when it is factored is (a + b + 2)(a + b - 2) = 0

If two parallel lines are cut by a transversal, then, Alternate Interior Angles are congruent. If two parallel lines are cut by a transversal, then, Alternate Exterior Angles are congruent. If two parallel lines are cut by a transversal, then corresponding angles are congruent.Using the above congruency rules and applying them to our question, we can say that for lines HN and KM to be parallel to each other, then;
∠GHI ≅ ∠KJH because they are corresponding angles

A picture of a swimming pool with a lifeguard sitting on an elevated chair on the right side of the pool. There is a person on a diving board on the left side of the pool who is lower than the lifeguard. The lifeguard is looking down at the person on the diving board and there is a solid line showing his line of sight. A dotted line is drawn from the lifeguard’s eyes horizontally. The angle between these two lines is labeled 1.
The distance between the two men is 7.2 ft. That is, they are 7.2 ft apart
Calculating DistanceFrom the question, we are to determine the distance between the two men
Let the distance between the men be x
From the given information,
The man of the diving board is 6 ft tall
and
The angle of elevation from the man in the water to the man on the diving board is 40°
Considering the triangle formed, we can write that
Opposite = 6 ft
Adjacent = x
Angle = 40°
From SOH CAH TOA, we have that
tan (angle) = opposite / adjacent
∴ tan 40° = 6 / x
x = 6 / tan 40°
x ≈ 7.2 ft
Thus,
The men are 7.2 ft apart

You bike 14 1/4
miles from your house to a state park. You travel 1/3
of that
distance in the woods. You bike along the bank of a stream for the last 1/2
of
the woods. On how many miles of your trip do you bike along the bank of
the stream?
By taking some products between fractions and mixed numbers, we will see that your trip along the bank has a length of (2 and 9/24) miles.
How many miles do you travel along the bank of the stream?Here we know that the total distance of the travel is (14 + 1/4) miles.
In this case, we know that 1/3 of that distance is traveled in the woods, so the total distance traveled in the woods is given by the product:
D = (1/3)* (14 + 1/4) mi = (14/3 + 1/12) mi
Now we know that 1/2 of the distance traveled in the woods is traveled along the bank of a strem, then the distance that we are looking for is given by the product:
D' = (1/2)*(14/3 + 1/12) mi = (7/3 + 1/24)mi
Now we can simplify that mixed number as:
(7/3 + 1/24)mi = (6/3 + 1/3 + 1/24) mi = (2 + 8/24 + 1/24)mi = (2 + 9/24) mi
Your trip along the bank of the stream has a length of (2 + 9/24) miles.

How many extra flowers did they order?
Answer:
B
Step-by-step explanation:
To find the number of extra flowers ordered, we can start by forming an equation based on the total amount paid by the customer.
Let the number of extra flowers be n.
Total paid
= cost of standard arrangement +(number of extra flowers)(cost per additional flower)
= $25 +n($1.25)
Given that the customer paid $45,
25 +1.25n= 45
Now that we have formed the equation, let's solve for n.
Subtract both sides by 25:
1.25n= 45 -25
1.25n= 20
Divide both sides by 1.25:
n= 20 ÷1.25
n= 16

In this Triangle, ΔUVW, UW is extended through point w to point x
∠ WUV = (3x - 4)°
∠ VWX = (6x + 6)°
∠ UVW = (x + 20)°,
the value of x is 5
According to the question, given that
∠ WUV = (3x - 4)°
∠ VWX = (6x + 6)°
∠ UVW = (x + 20)°
because ∠ VWX = ∠ WUV + ∠ UVW
⇒ (6x + 6) = (3x - 4) + (x + 20)
⇒ (6x + 6) = 4x + 16
⇒ 2x = 10
⇒ x = 5
{The sum of triangle's interior angles is 100°}
{The sum of supplementary angles is 180°}
Therefore, In ΔUVW, UW is extended through point w to point x, then the value of x is 5.
The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. By deducting the angle of the target vertex from 180°, one can also determine a triangle's exterior angle.

Consider side opposite to ∠A=a ,∠B=b ,∠C=c
Given side length
AC=b

Using cosine law
cos A= (b²+c²-a²)/2bc
⇒cos36°= [20²+12²-(x+12)²]/2(20)(12)
⇒(1+√5)/4=(544-x²-24x-144)/480

mass. What mass of each ingredient is
needed to make the following amounts of
snack mix?
a) 330 g
b) 210 g
c) 500 g
d) 750 g
The mass of ingredient is given by 66g, 45g, 100g, 150g.
What is mass?
Mass is a parameter of measurement that calculates how much matter is contained in a body.
Mass is a physical quantity. Mass is measured in terms of the weight of a body. Gram, kilogram, and pounds are some standard mass units to measure it. The SI unit of mass is the kilogram; however, smaller objects are measured in grams.
Given, the ratio of the ingredients by mass as 2:2:1.
Let x be the mass of the ingredients.
A) total mass is given by 330g
therefore, 2x+2x+1x = 330
5x = 330
x = 330/5
x = 66
Hence the mass of oat = 2(66) = 132g
mass of cereal = 2(66) = 132 g
mass of nuts = 66g
B) 2x+2x+1x = 210
5x = 210
x = 210/5
x = 42g
Hence, the mass of oat = 2(42) = 84g
mass of cereal = 2(42) = 84 g
mass of nuts = 84
C) 2x+2x+1 = 500
5x = 500
x = 100
hence, the mass of oat = 2(100) = 200g
mass of cereal = 2(100) = 200 g
mass of nuts = 100g
D) 2x+2x+1 = 750g
5x = 750
x = 750/5
x = 150
Hence, the mass of oat = 2(150) = 300g
mass of cereal = 2(150) = 300 g
mass of nuts = 150g
