Answer:
about 21.9 ft²
Step-by-step explanation:
area of a half circle = [tex]\frac{\pi r ^{2} }{2}[/tex]
so [tex]\frac{\pi 3^{2} }{2} = 14.13716694[/tex] ft²
are of a square is [tex]bh\\[/tex]
so 6 x 6 = 36 ft²
so the area of the figure would equal the area of the square minus the area of the half-circle
36 ft² - 14.13716694 ft² = 21.86283306 ft² ≈ 21.9 ft²

P(-5, 2), Q(4, 5), R(6, – 1), S(-3, -4)
this is a rectangle right and why is it and not rhombus or square?
Answer:
It's a rectangle, but not a rhombus (or square).
Step-by-step explanation:
Let's see the vectors of each next vertex:
[tex]Q - P = (4, 5) - (-5, 2) = (9, 3)\\R - Q = (6, -1) - (4, 5) = (2, -6)\\S - R = (-3, -4) - (6, -1) = (-9, -3)\\P - S = (-5, 2) - (-3, -4) = (-2, 6)\\[/tex]
Firstly, we can notice that it's a parallelogram - because the Q-P side is parallel to the S - R side (if the x:y ratios are the same, the sides are parallel).
A rhombus needs the sides to be of the same length. But the length of a (x, y) vector is [tex]\sqrt{x^2 + y^2}[/tex] and [tex]\sqrt{9^2 + 3^2} > \sqrt{2^2 + (-6)^2}[/tex], we don't even have to compute it exactly. If it's not a rhombus, it's also not a square (every square is a rhombus).
The last thing left is to know if it's a rectangle - for it to be a rectangle, we need to check if the vectors are perpendicular.
We can compute the dot product of the vectors - perpendicular vectors always have a dot product equal to zero. The dot product of two vectors [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is equal to [tex]x_1x_2 + y_1y_2[/tex].
[tex](9, 3) \cdot (2, -6) = 9\cdot 2 + 3\cdot(-6) = 18 - 18 = 0[/tex]
So the sides are perpendicular, and as such - the figure is a rectangle.

Answer:
New coordinates:
A = (-2, 1)
B = (0, 1)
C = (2, -3)
D = (0, -3)
Step-by-step explanation:
First, determine the ordered pairs for ABCD.
A = (2, 4)
B = (4, 4)
C = (6, 0)
D = (4, 0)
Horizontal movement will only affect the x coordinates of the ordered pairs. Horizontal movement includes moving to the right and left.
Vertical movement will only affect the y coordinates of the ordered pairs. Vertical movement includes moving up and down.
The question asks us to translate 4 units to the left. Moving left on the graph means we will subtract 4 from the x coordinates. The question also asks us to translate 3 units down. Moving down also means subtraction, but from the y coordinate.
New A = (2 - 4, 4 - 3) = (-2, 1)
New B = (4 - 4, 4 - 3) = (0, 1)
New C = (6 - 4, 0 - 3) = (2, -3)
New D = (4 - 4, 0 - 3) = (0, -3)
The new translation will have A at (-2, 1), B at (0, 1), C at (2, -3), and D at (0, -3).
A game has green and blue pieces the ratio of green game pieces to total pieces is 5:12. What are some statements that are true answer fast
Answer:
Statement B and statement D are true
Step-by-step explanation:
A game has green and blue pieces. The ratio of
green game pieces to total pieces is 5:12.
Select all the statements that are correct about the game pieces.
A. The ratio of green pieces to blue pieces is 7:5.
B. The ratio of total pieces to blue pieces is 12:7,
C. There must be 7 more blue pieces than green pieces.
D. The ratio of total pieces to green pieces is 12:5.
Ratio of green pieces = 5
Ratio of total pieces = 12
Ratio of blue pieces = Ratio of total pieces - Ratio of green pieces
= 12 - 5
= 7
Ratio of blue pieces = 7
A. The ratio of green pieces to blue pieces is 7:5.
Green pieces : blue pieces = 5 : 7
A is not true
B. The ratio of total pieces to blue pieces is 12:7
Total pieces : blue pieces = 12 : 7
B is true
C. There must be 7 more blue pieces than green pieces.
Blue = 7
Green = 5
There are 2 more blue pieces than green pieces
C is not true
D. The ratio of total pieces to green pieces is 12:5
Total pieces : green pieces = 12 : 5
D is true

The graph of a linear function is shown.
Which word describes the slope of the line?
• positive
• negative
O zero
O undefined
The slope of the line as shown in the graph of the linear function in the image below is: negative.
What is the Slope of a Line of a Linear Function?The slope of a line of a linear function = change in y/change in x.
The value of the slope would be positive if the graph increases upwards from your left to your right.
The value of the slope would be negative if the graph decreases downwards from your left to your right.
Thus, the slope of horizontal lines are always zero while the slope of vertical lines are undefined.
Therefore, the slope of the line as shown in the graph of the linear function in the image below is: negative.

What is addition of two fractions?To add fractions there are three simple steps:
Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator.
Step 3: Simplify the fraction (if possible)
Given, after six months, she improved her record by 1/15 of a kilometer. After a year, she further improved her record by 1/12 of a kilometer.
Now, 5/6 + 1/15 + 1/12
LCM of denominators 6, 15 and 12 is 60.

Lines CD and DE are tangent to circle A shown below: Lines CD and DE are tangent to circle A and intersect at point D. Arc CE measures 112 degrees. Point B lies on circle A. If Arc CE is 112°, what is the measure of ∠CDE? (4 points) Question 5 options: 1) 124° 2) 136° 3) 68° 4) 56°
Answer:
Option (3)
Step-by-step explanation:
By the theorem, angle between two tangents intersecting each other outside the circle is half of the difference between intercepted arcs.
From the figure attached,
Two tangents CD and DE are intersecting each other at point D outside the circle A.
Two intercepted arcs are minor arc CE and major arc CBE,
Measure of arc CE = 112°
Therefore, measure of major arc CBE = 360° - 112°
= 248°
m(∠CDE) = [tex]\frac{1}{2}(\text{arcCBE}-\text{arcCE})[/tex]
= [tex]\frac{1}{2}(248-112)[/tex]
= [tex]\frac{1}{2}\times 136[/tex]

Step-by-step explanation:

1. A signal tower has two lights that are 30 feet apart from each other, one directly above the other. From
a boat, the angle of elevation of the lower light is 14 degrees, and the angle of elevation yo the upper
light is measured to be 32 degrees.
a) Find to the nearest foot the distance from the boat to the lower light.
b) The boat and the foot of the tower are in the same horizontal plane. Find to the nearest foot the
distance from the boat to the foot of the tower.
Solution :
It is given that the distance between the two lights is 30 feet.
The angle of elevation of the upper light from the boat, ∠ ABP = 32 degree
The angle of elevation of the lower light from the boat, ∠ ABQ = 14 degree
∴ ∠ PBQ = ∠ ABP - ∠ ABQ
= 32 - 14
= 18 degree
In triangle PAB
∠ PAB = 180 - (90 + 32)
= 58 degree
Similarly in triangle AQB
∠ AQB = 180 - (90 + 14)
= 76 degree
Now considering triangle PBQ and applying the sine theorem,
[tex]$\frac{PQ}{\sin 18}=\frac{BQ}{\sin 58}$[/tex]
we know PQ = 30 feet
∴ [tex]$BQ =\frac{\sin 58}{\sin 18} \times 30$[/tex]
= 82.33 feet
Again taking the right triangle ABQ and applying sine theorem,
[tex]$\frac{BQ}{\sin 90}=\frac{AB}{\sin 76}$[/tex]
[tex]$\frac{82.33}{\sin 90}=\frac{AB}{\sin 76}$[/tex]
∴ [tex]$AB = 82.33 \times \sin 76$[/tex]
= 79.88 ft
= 80 feet

Answer:
The answer that is not true when x = -4 is B.
Step-by-step explanation:
Since x = -4, that means all we have to do to eliminate answers is plug -4 in place of x.
A is incorrect because 2 × -4 = -8, which means that answer IS true and we're looking for the one that isn't true.
Same with C, -4 + -4 + -4 added together gives you -12 = -12, therefore isn't the right choice.
Finally D. -4/4 divided equals -1, so that would make it -1 = -1.
B is the only one that doesn't make sense, therefore you have your answer.
