I need help QUICKLY on this algebra question!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
x = -1
Step-by-step explanation:
to find axis of symmetry, use the following equation:
x = -b/2a
in this problem, a = 3, b = 6, c = -12
x = -6/2(3)
x = -6/6
x = -1
Find the volume to the nearest millimeter of a cylinder that is 45 millimeters tall and has a diameter of 26 millimeters. Use 3.14 for pie.
Answer:
Volume = π • r² • height
Volume = 3.14 • 13² • 45
Volume = 23,879.7 cubic millimeters
Volume = 23,880 cubic millimeters (to nearest millimeter)

1. The top surface of a model building is composed of 2 rectangles and a triangle. Some side lengths of the top surface of the counter are shown. What is the area of the top surface of the model building.
Answer:
8.625 feets²
Step-by-step explanation:
Based on measurement illustrated in the attached picture :
There are two rectangles and one triangle :
Area of first rectangle :
Area = Length * width
Length = 1.5 ft ; width = 2.5 ft
Area = 1.5 * 2.5
Area = 3.75 ft²
Area of triangle = 1/2 * base * height
Base = 1.5 ; height = 1.5
Area = 1/2 * 1.5 * 1.5
Area = 1.125 ft²
Area of second rectangle :
Area = Length * width
Length = 1.5 ft ; width = 2.5 ft
Area = 1.5 * 2.5
Area = 3.75 ft²
Total area :
(3.75 + 3.75 + 1.125) feets
= 8.625 feets²

What in trying to find is 95-3into4 3 for 4 times. 95-3x3x3x3=_____. What can i do for this answer. ☠️~_~-_- -_-||
Answer:
14
Step-by-step explanation:
To evaluate 95 minus 3, four times
95 - 3⁴
95 - (3 * 3 * 3 * 3)
95 - (81)
95 - 81
= 14
Hence, 95 - (3 * 3 * 3 * 3) = 14
Jamal performed an experiment flipping a coin. He did 10 trials and then his arm got tired. He recorded his results in the table. Based on the experimental probability, Jamal predicted that the number of times the coin lands heads up will always be greater than the number of times it lands tails up. What is the error in his prediction?
Answer:
The error in his prediction is that he had too small of a sample size for the data to be reliable in how the trend would continue.
Answer:
He did not perform enough trials to compare the theoretical and experimental probabilities.

Whats the area of a circle with a circumference of \blueD{50.24}50.24start color #11accd, 50, point, 24, end color #11accd units.
Answer:
[tex]A=200.96\ unit^2[/tex]
Step-by-step explanation:
Given that,
The circumference of the circle, C = 50.24 units
We need to find the area of the circle.
The formula for the circumference of the circle is given by :
[tex]C=2\pi r[/tex]
r is the radius of the circle
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{50.24}{2\times 3.14}\\\\r=8\ units[/tex]
The formula for the area of a circle is given by :
[tex]A=\pi r^2\\\\A=3.14\times 8^2\\A=200.96\ unit^2[/tex]
So, the area of the circle is equal to [tex]200.96\ unit^2[/tex].
