Answer:
(-2, 3)
Step-by-step explanation:
the point B is
B(x,y)
x
AB (A to B) is twice BC ( B to C )
AB is 2 - x. BC is x - (-4)= x + 4
So
2-x=2 (x + 4)
2-x=2x + 8
3x = -6
x = -2
y
(Same logic as above)
AB is -5 -y. BC is u - 7
-5 -y = 2(y - 7)
-5 - y = 2y - 14
3y = 9
y= 3
the point is (-2, 3)

a tiny but horrible alien is standing at the top of the empire state building (which is 443443443 meters tall) and threatening to destroy the city of new york! a men in black agent is standing at ground level, 181818 meters across the street, aiming his laser gun at the alien. at what angle, in degrees, should the agent shoot his laser gun?
The angle for shooting laser gun should be 89.98°.
The vertical height where a tiny but horrible alien is standing is given as 443443443 meters. The horizontal distance of a men in black agent from building is given in the question as 181818 meters. So, let us assume the angle formed to be theta (θ).
Writing the formula for tan theta, that relates the given height and distance
Now, tan θ = vertical height ÷ horizontal distance
Keep the values in above mentioned equation of theta to find the angle.
tan θ = [tex]\frac{443443443}{181818}[/tex]
Performing division to find the tan theta and subsequently calculate the angle
tan θ = 2438.94
θ = tan⁻¹ 2438.94
Calculating tan inverse to find the value of theta
θ = 89.98°
Therefore, the angle for shooting laser gun by a men in black agent should be 89.98°.

Kat is painting the edge of a triangular stage prop with reflective orange paint. the lengths of the edges of the triangle are (3x – 4) feet, (x2 – 1) feet, and (2x2 – 15) and x = 4
Now , According to the question:
Let the sides of triangle be a , b , c
a = 3x -4
b = x^2 -1
c = 2x^2 - 15
x = 4
Substitute the value of x in a, b , c
a = 3 × 4 -4 = 8 feet
b = 4 × 4 -1 = 15 feet
c = 2× 4× 4 - 15 = 17 feet
The perimeter of the triangle is sum of all sides
then, a + b + c
= 17 + 15 + 8 = 40 feet

Find the volume of the figure
Answer: 5 m³
Step-by-step explanation:
We will break the figure into two different parts.
Volume of a rectangular prism can be found with V = L * W * H
V = L * W * H
V = (2 m) * (1.5 m) * (1.5 m)
V = 4.5 m³
-
V = L * W * H
V = (2 m) * (2 m - 1.5 m) * (0.5 m)
V = 0.5 m³
Now, we will add them together.
4.5 m³ + 0.5 m³ = 5 m³
Answer:
5m³
Step-by-step explanation:
Hello!
You can picture this rectangular prism as a whole prism with a part removed.
The dimensions of the whole prism are 1.5m, 2m, and 2m.
The part cut out is 1m, 0.5m, and 2m.
We can find the volume of the whole rectangular prism and subtract the volume of the removed part.
Find the volume(1.5 * 2 * 2) - (1 * 0.5 * 2)6 - 15Since the units of length are meters, the volume should be represented as meters³. The volume is 5m³.

Reason:
There are two mountain peaks, which show the two modes (at 0.27 and 0.31). Therefore, this data set is bimodal.
The data set is also symmetric because of the mirror line at 0.29; stuff to the left of 0.29 can be reflected over the mirror line to get the stuff on the right side.
We can rule out choice A since the curve doesn't represent a normal distribution. A normal distribution has exactly one mode only.
Choice C is ruled out because a skewed distribution isn't symmetric, and vice versa.
The data set isn't uniform since all stacks of points aren't the same height. This rules out choice E.
