1. S(–4, –4), P(4, –2), A(6, 6) and Z(–2, 4) a) Apply the distance formula for each side to determine whether SPAZ is equilateral. b) Apply the slope formula to determine whether the diagonals are perpendicular. c) Apply the midpoint formula to each diagonal to determine whether the diagonals bisect each other.
Answers
Answer:
a) SPAZ is equilateral.
b) Diagonals SA and PZ are perpendicular to each other.
c) Diagonals SA and PZ bisect each other.
Step-by-step explanation:
At first we form the triangle with the help of a graphing tool and whose result is attached below. It seems to be a paralellogram.
a) If figure is equilateral, then SP = PA = AZ = ZS:
[tex]SP = \sqrt{[4-(-4)]^{2}+[(-2)-(-4)]^{2}}[/tex]
[tex]SP \approx 8.246[/tex]
[tex]PA = \sqrt{(6-4)^{2}+[6-(-2)]^{2}}[/tex]
[tex]PA \approx 8.246[/tex]
[tex]AZ =\sqrt{(-2-6)^{2}+(4-6)^{2}}[/tex]
[tex]AZ \approx 8.246[/tex]
[tex]ZS = \sqrt{[-4-(-2)]^{2}+(-4-4)^{2}}[/tex]
[tex]ZS \approx 8.246[/tex]
Therefore, SPAZ is equilateral.
b) We use the slope formula to determine the inclination of diagonals SA and PZ:
[tex]m_{SA} = \frac{6-(-4)}{6-(-4)}[/tex]
[tex]m_{SA} = 1[/tex]
[tex]m_{PZ} = \frac{4-(-2)}{-2-4}[/tex]
[tex]m_{PZ} = -1[/tex]
Since [tex]m_{SA}\cdot m_{PZ} = -1[/tex], diagonals SA and PZ are perpendicular to each other.
c) The diagonals bisect each other if and only if both have the same midpoint. Now we proceed to determine the midpoints of each diagonal:
[tex]M_{SA} = \frac{1}{2}\cdot S(x,y) + \frac{1}{2}\cdot A(x,y)[/tex]
[tex]M_{SA} = \frac{1}{2}\cdot (-4,-4)+\frac{1}{2}\cdot (6,6)[/tex]
[tex]M_{SA} = (-2,-2)+(3,3)[/tex]
[tex]M_{SA} = (1,1)[/tex]
[tex]M_{PZ} = \frac{1}{2}\cdot P(x,y) + \frac{1}{2}\cdot Z(x,y)[/tex]
[tex]M_{PZ} = \frac{1}{2}\cdot (4,-2)+\frac{1}{2}\cdot (-2,4)[/tex]
[tex]M_{PZ} = (2,-1)+(-1,2)[/tex]
[tex]M_{PZ} = (1,1)[/tex]
Then, the diagonals SA and PZ bisect each other.

Step-by-step explanation:
A vertical line has a slope that is "undefined". Line R is the vertical line on your graph
___________
The slope of a vertical line is "undefined" because of the way slope is defined. Slope is the vertical change divided by the horizontal change. When the line is vertical, there is no horizontal change, so the computation of slope involves division by zero. The result of division by zero is "undefined."

7/10 is 70% of the container's full capatcity.
20% - 70% = 50%
By adding 14 gallons of water, the container's water went up by 50%.
If we multiply 14 by 2, we will know what the container can hold at 100% capatcity.

What is the probability of drawing a face card from a standard deck of cards and rolling a 3 or more on a 20-sided dice?
Write your answer in percent format but do not include the symbol.
Write and round your answer to the nearest hundredth
Answers
Answer: 20.77%
Step-by-step explanation:
There are 52 cards in a standard deck. Out of these cards, there are 12 face cards. Thus, the probability of drawing a face is 12/52.
On a 20-sided dice, there are 20 options of numbers to roll. Out of these 20 numbers, 18 of the numbers are greater than or equal to 3, making the probability 18/20, or 9/10.
To find the probability of two events, you need to multiply the probabilities together. Thus, you need to multiply 12/52 by 9/10.
(12/52) * (9/10) = 27/130
27/130 is about equal to 0.2077, or a 20.77% probability.
Aiko stands 5 m from a tree. At that distance, the angle of elevation from the ground to the top of the tree is 80°.
Approximately how tall is the tree?
Answers
Answer:
[tex]\boxed {\boxed {\sf About \ 28.36 \ meters }}[/tex]
Step-by-step explanation:
Assuming the tree is perpendicular to the ground, we can use the right triangle trigonometric ratios to find the tree's height.
sin(θ)= opposite/hypotenuse cos(θ)= adjacent/hypotenuse tan(θ)= opposite/adjacentNow, let's draw a diagram. We know Aiko is 5 meters from the base of the tree. From there, the angle to the top of the tree is 80 degrees. We are looking for x, the tree's height. The diagram attached is not to scale.
We base the sides off of the angle. x is opposite of 80 degrees and 5 is adjacent. Therefore we must use tangent.
[tex]tan(\Theta)=\frac{opposite}{adjacent}[/tex]
opposite=x adjacent=5 mθ=80Substitute in the known variables.
[tex]tan(80)=\frac{x}{5 \ m }[/tex]
We want to find x, the height of the tree. Therefore we need to isolate that variable.
x is being divided and the inverse operation is multiplication. Multiply both sides of the equation by 5 meters.
[tex]5 \ m* tan(80)=\frac{x}{5 \ m }* 5 \ m[/tex]
[tex]5 \ m* tan(80)=x[/tex]
[tex]5 \ m *5.67128182=x[/tex]
[tex]28.3564091 \ m = x[/tex]
The question asks for an approximation, so let's round to the nearest hundredth.
The 6 in the thousandth place tells us to round the 5 to a 6.
[tex]28.36 \ m \approx x[/tex]
The tree is about 28.36 meters tall.

Step-by-step explanation:
Use the compound interest formula:
A = P( 1 + r/n)^nt
A is the amount at the end
P is the principal or original amount.
R is annual rate as a decimal (you have to convert)
N is the # of compounding periods in a year (quarterly means 4)
T is time in years
A = 500( 1 + 0.0475/4)^(4×20)

The surface area for a rectangular prism is given by the formula SA = 2ab + 2bc + 2ac, where a, b, and c are the lengths of the prism. If the surface area of a rectangular prism with side c measuring 12 meters is 434 square meters and length of side a measuring the same length as side b, then what is the length of side a of the rectangular prism?
Answers
Answer:
We are given
We are also given and , which allows us to rewrite the equation as
(I substituted every "b" with "a" and every "c" with "9").
The solutions to this quadratic equation are -25 and 7. We discard -25 because a side with negative length would make no sense.
The required measure of side a of the rectangular prism is a = 9.3 meters.
What is surface area?The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
Here,
SA = 2ab + 2bc + 2ac
434 = 2a² + 14a + 14a
434 = 2a² + 28a
2a² + 28a - 434 = 0
a² + 14a - 217 = 0
a² + 14a + 49 - 49 - 217 = 0
(a + 7)² = 266
a = 9.3 or a = -23.3
Since the negative measure of length can be neglected.
a = 9.3 = b
Thus, the required measure of side a of the rectangular prism is a = 9.3 meters.
