Yes, the triangle can be easily formed for the sides 7 cm, 5 cm and 3 cm.
According to the side side side rule of triangle, if the sum of the any two sides of triangle is more than third side, it will form a triangle. Let us check the same by assuming side a to be 7 cm, side b to be 5 cm and side c to be 3 cm.
Side a + side b > side c
7 + 5 > 3
Add the digits in Left Hand Side of the equation
12 > 3
Side b + side c > side a
5 + 3 > 7
Add the digits in Left Hand Side of the equation
8 > 7
side c + side a > side b
3 + 7 > 5
Add the digits in Left Hand Side of the equation
10 > 5
We see that the two sides of the triangle are greater than third side, hence, it is possible to form the triangle.

From the linear function that is represented by the table, we can conclude that the slope is -2, and the y-intercept is 12.
Linear function
The linear function is an equation for a line that can be written by finding the slope between two points on that line, then finding the y-intercept by using the slope-intercept equation: y=mx+b, where b represents the y value of the y-intercept point.
Now we take a look at the following data:
X Y
–3 18
0 12
3 6
6 0
We want to know the slope by picking two out of four given points, let's say we pick the first two points:
y - y₀ = m (x - x₀)
(18 - 12) = m (-3 - 0)
6 = m * -3
m = 6 / -3
m = -2
Thus the slope is -2.
Now we substitute the slope value to one of the points, let's say we pick the first point:
(x₀, y₀) = (-3, 18)
y - y₀ = m (x - x₀)
y - 18 = -2 (x - (-3))
y = -2x - 6 + 18
y = -2x + 12
Thus the y-intercept of the linear function is 12.

What is Pythagoras theorem?
The hypotenuse's square is equal to the sum of the squares of the other two sides if a triangle has a straight angle (90 degrees), according to the Pythagoras theorem. Keep in mind that BC2 = AB2 + AC2 in the triangle ABC signifies this. Base AB, height AC, and hypotenuse BC are all used in this equation. The longest side of a right-angled triangle is its hypotenuse, it should be emphasized.
Now using the Pythagoras theorem we can find out the length of the other wall
b²=h²-p²
The distance from home plate to the 2nd base will be
b²=h²-p²
h² = b²+p²
h² = 2*90²
h² = 2*90²
h² = 2*8100
h² = 16200
h = 127.27

How do you solve if an equation is a function?For any input, a function will only have one or no outputs. The equation does not define a function if a given input has more than one output. Each value of x must have a maximum of one output value of y in order to be considered a function. To determine the slope of a graphed function, use the average rate of change formula.
The average rate of change from a to some other value x is what determines the instantaneous rate of change at some time[tex]x_{0} =a[/tex]. The average rate of change from x=a+h to x=a is y x = f(x) f(a) x a =f (a + h) f( a ) h if h = 0 and a = f ( a + h ) f (a) h are set.

You can conclude that it took you less time on Tuesday to run to and from the playground than it did on Monday.
What is the distance?Distance is defined as the product of speed and time.
To compare the times it took to go to and from the playground each day, you need to calculate the total time for each day.
On Monday, it took 22 minutes to run to the playground and 25 minutes to run back home, for a total time of 47 minutes.
On Tuesday, you ran the entire 4 1/2 miles at a constant speed of 6 1/4 miles per hour, so you can use the formula:
distance / speed = time.
In this case, 4.5 miles / 6.25 mph = 0.72 hours or 43.2 minutes.

What is the formula for finding the area of a triangle with an unknown height?
The formula for finding the area of a triangle with an unknown height is: Area = (Base * Height) / 2. This formula uses the base length of the triangle, multiplied by the height of the triangle, then divided by 2.
The formula for finding the area of a triangle with an unknown height is: Area = (Base * Height) / 2. This formula uses the base length of the triangle, multiplied by the height of the triangle, then divided by 2. To use this formula, start by determining the base length of the triangle. This is the length of any one side of the triangle. Once the base is determined, use the formula to calculate the area. In the formula, the base is multiplied by the height of the triangle. Since the height is unknown, use the Pythagorean Theorem to calculate it. The Pythagorean Theorem states that the square of the hypotenuse (the longest side of the triangle) is equal to the sum of the squares of the other two sides. Once the hypotenuse is known, the height can be found by using the formula (Height = Hypotenuse - Base) / 2.

How do you write 0.02 in exponential form?
The given number 0.02 can be written in exponential form as [tex]2 \times 10^{-2}[/tex] , because to express small number in exponential form power of 10 notation is used .
To write the number 0.02 to exponential form ,
the first step is to move the decimal point to right until it is after the first non zero digit.
In this number we move the decimal point to move two spaces to right.
So , the number becomes ; [tex]\frac{2}{100}[/tex] ;
Now , we multiply the number 2 we created by 10 having exponent of -2. we know that , Whenever decimal point moves to right, the exponent of 10 will be a negative exponent.
The number after the decimal point is always equal number of spaces decimal point moves.
So , the final exponential form of 0.02 is [tex]2 \times 10^{-2}[/tex] .

Answer:
325 adults and 612 students entered the school play
Step-by-step explanation:
1st equation: x is the number of adults and y the number of students.
2nd equation: Students times what they payed + adults times what they payed:
1st: x + y = 937
2nd: 2x + 0.75y = 1109
x = 937 - y
Now let's replace x for (937 - y) in the 2nd equation, to find out the value of y:
2(937 - y) + 0.75y = 1109
1874 - 2y + 0.75y = 1109
1874 - 1.25y = 1109
-1.25y = 1109 - 1874
-1.25y = -765 (multiply -1)
1.25y = 765
y = 765 / 1.25
y = 612
Now that we found the y value, let's replace it in the 1st equation to find out the value of x:
x + 612 = 937
x = 937 - 612
x = 325
If you want to double check it, you can replace both in the 2nd equation, to make sure:
2 * 325 + 0.75 * 612 = 1109
650 + 459 = 1109 (checked)

In mathematics, scaling is often represented by a scaling factor, which is a number used to multiply the coordinates of the object. Scaling can be applied to geometric shapes, vectors, and functions, and it can be done in one or multiple dimensions. Uniform scaling means that the object is scaled by the same factor in all dimensions. Non-uniform scaling means that the object is scaled by different factors in different dimensions.
B(-1, 0), M(-1, 1), and S(1, -6)
scaling factor (k) = 4.5
after scaling,
B'(-4.5, 0), M'(-4.5, 4.5), S'(4.5, -27)
