Answer:
Isosceles triangle.
Step-by-step explanation:
On the basis of the lengths of the sides of a triangle, below are three types of triangles.
Equilateral triangle: The triangle in which the lengths of all sides are equal.
Isosceles triangle: The triangle in which the lengths of any two sides are equal.
scalene triangle: The triangle in which the lengths all the three sides are different.
Here, the length of the sides are 24 24 and 4.
Since, two sides are equal in length.
Hence, it is an Isosceles triangle.

Answer:
V = 15.75w² + 10.5w
Step-by-step explanation:
A rectangular prism is the same as a cuboid and the volume of a cuboid is length multiplied by width multiplied by the height.
And we were provided with the following:
Length = 5.25cm
Width is unknown,= w
The height is said to be 2cm longer than 3 times it's width.
The above statement can be mathematically represented as ;
H = 3w + 2
Apply the above into the formula given and we have
5.25 × w × (3w + 2)
Expand the above and we have
V = 5.25w × (3w + 2)
V = 15.75w² + 10.5w
The line of best fit is a line that follows the direction of the dots. It doesn't have to be perfect, it's just a general line to represent the data. Sometimes there isn't a line of best fit (if there is no correlation). It normally touches most of the dots.
The slope is about 1/2 and the point where the line touches the y axis is at 40 so that means an equation could be y = 1/2x + 40
When the advertising expenditure (x value) is 18,000, substitute it into the equation above. y = 1/2(18,000) + 40 which equals y = 9,040 . This is the expected revenue.
Hope this helps!
D(t) = -4t^3 + 40t^2 + 500t = 4088
4t^3 - 40t^2 - 500t + 4088 = 0
t = 7
Therefore, the plane has flown 4088 km 7 hours after it took off.
