Question 4 Objective: Apply properties of squares to solve mathematical and real-world problems. The perimeter of a square is 116 cm. What is the approximate length of its diagonal?
help
Answers
Answer:
41.01 cm
Step-by-step explanation:
Answer:
41.0 cm
Step-by-step explanation:
The side length is 1/4 the length of the perimeter.
s = P/4
The diagonal length is √2 times the side length.
d = s·√2
Then the diagonal is ...
d = (P/4)√2 = (116 cm)(√2)/4 ≈ 41.01 cm
The diagonal is about 41.0 cm long.

FunctionNot a functionFunctionNot a function========================================
Explanation:
If x repeats itself, then we don't have a function. For instance, relation 2 has the x value -4 show up twice. That input leads to multiple outputs which is why we don't have a function. Relation 4 is a similar story (this time the input 'u' shows up twice).
Relations 1 and 3 don't have this issue, so they are functions.

Find the area of a circle with diameter, d = 2m.
Give your answer in terms of pi
Answers
Answer:
A = π m²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here d = 2 , then r = 2 ÷ 2 = 1
A = π × 1² = π × 1 = π m²
Write a system of linear inequalities represented by the graph?
Inequality 1:
Inequality 2:
Answers
Answer:
y > x - 2
y >= 5x + 1
Step-by-step explanation:
Linear inequalities represented by the graph are y>5x+1 and y>x-2
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The first line passes through the points
(0, 1) and (-1, -4)
The slope of line is m=-4-1/-1=5
Let us find the y intercept
1=5(0)+b
b=1
So the equation of line is y=5x+1
As the shading is outside so y>5x+1
Now let us find for 2nd line
(2, 0) and (-2, -4)
m=-4/-4=1
Now y intercept is 0=2+b
b=-2
So equation is y=x-2
As shading is outside so y>x-2
Hence, linear inequalities represented by the graph are y>5x+1 and y>x-2

Step-by-step explanation:
Using these points, we can determine that the equation is as follows:
Line B: y = -2/3x + 7/3
And since Line A has the same slope, it would make Line A's equations like this:
Line A: y = -2/3x - 11/3
This makes these equations Parallel to each other because they have the same slope with different y-intercepts.
