Answer:
18.6cm
Step-by-step explanation:
there is a theorem that states that the midsegment of a triangle (midpoint to midpoint, in this case X and Y) is half of the base (in this case BC)
when applied to the triangle shown:
XY= 1/2 BC
substitute to get
XY=1/2*6.4
XY=3.2
perimeter of BCYX
=XY+YC+CB+BX
=3.2+4+6.4+5
=18.6cm

Which of the following equations contains the point (8, 5) and is perpendicular to the line y = 2x − 3?
Answer:
[tex]y = \ -\displaystyle\frac{1}{2}x \ + \ 9[/tex]
Step-by-step explanation:
Given that the reference line is y = 2x - 3, with a slope of [tex]m_{reference} \ = \ 2[/tex].
We know that two non-vertical lines are perpendicular if the slope of one line is the negative reciprocal of the slope of the other. In other words, both slopes can be multiplied together to yield -1. Let [tex]m_{1}[/tex] be the slope of one line and [tex]m_{2}[/tex] be the slope of its corresponding perpendicular line,
[tex]m_{1} \ \times \ m_{2} \ = \ -1 \ \ \ \ \ \ \ \ \ \ \ \mathrm{or} \ \ \ \ \ \ \ \ \ \ \ m_{1} \ = \ \displaystyle\frac{-1}{m_{2}}[/tex].
Thus,
[tex]m_{reference} \ \times \ m_{perpendicular} \ = \ -1 \\ \\ \-\hspace{2.26cm} m_{perpendicular} \ = \ \displaystyle\frac{-1}{m_{reference}} \\ \\ \-\hspace{2.26cm} m_{perpendicular} \ = \ \displaystyle\frac{-1}{2} \\ \\ \-\hspace{2.26cm} m_{perpendicular} \ = \ -\displaystyle\frac{1}{2}[/tex]
Therefore, using the point-slope form for the equation of a line passing through the point [tex](x_{1}, \ y_{1})[/tex] is [tex]y \ - \ y_{1} \ = \ m(x \ - \ x_{1})[/tex]. Given that the perpendicular line passes through the point [tex](8,\ 5)[/tex], the equation of the perpendicular line is
[tex]y \ - \ 5 \ = \ -\displaystyle\frac{1}{2}(x \ - \ 8) \\ \\ y \ - \ 5 \ = \ -\displaystyle\frac{1}{2}x \ + \ 4 \\ \\ \-\hspace{0.85cm} y \ = \ -\displaystyle\frac{1}{2}x \ + \ 9[/tex]

The radius of a circle is 19 miles. What is the circle's circumference?
Answer:
119.32 miles
Step-by-step explanation:
radius=19 miles
circumference =2×3.14×19 miles
The circle's circumference 119.32 miles
What is circle's circumference ?Circumference of the circle or perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of circle defines the region occupied by it. If we open a circle and make a straight line out of it, then its length is the circumference. It is usually measured in units, such as cm or unit m.
GIven that, radius of a circle is 19 miles
we know , circumference of circle = [tex]2\pi r[/tex]
= [tex]2\pi \cdot19[/tex]
= 38 (3.14)
= 119.32 miles
Hence, circle's circumference 119.32 miles

snowboard is advertised to be 60% of the original price. If the sale price is $180, use a double number line determine the original price.
Step-by-step explanation:
60% of original price X = $180
60/100 × X = $180
60X/100= $180( cross multiply)
60X= 18000
X= 18000÷60
X= $300

What would be the amount of shortage if a price ceiling is imposed at price of $205?
Your Answer: 1100
Answer
Answer:
525
Step-by-step explanation:
The demand at a price of 205 is ...
Qd = 2600 -5(205) = 2600 -1025 = 1575
The supply at a price of 205 is ...
Qs = -1000 +10(205) = 2050 -1000 = 1050
The demand exceeds the supply by ...
1575 -1050 = 525
The shortage is 525 units.

Answer:
(2,5) -- that is, x is 2, and y is 5, so it would be choice A.
Step-by-step explanation:
5(2x+1)-7x=11
10x+5-7x=11
3x=6
x=2
y=2(2)+1=5
Convert the equation to polar form. (Use variables r and as needed.)
x2 − y2 = 12
In converting to polar coordinates, we take
x = r cos(t)
y = r sin(t)
Then in the given equation,
x² - y² = 12
(r cos(t))² - (r sin(t))² = 12
r² cos²(t) - r² sin²(t) = 12
r² (cos²(t) - sin²(t)) = 12
r² cos(2t) = 12
r² = 12 sec(2t)
A rule for creating a pattern is given below.
Rule: Subtract 7 from 2 to get y.
Which ordered pair, (x, y), works for the rule?
Answer:
(any real number, 5)
Step-by-step explanation:
Well given that y=7-2 and that y=5, we do not know the value of x, therefore x could be any real number with y being 5. I'm pretty sure that answered your question. So, a example of an ordered pair that would fit this rule would be say (5,5) or (7,5)

Double the number and subtract the corresponding value from the sequence
0, 0, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5...
1 + 1 - 0 = 2
2 + 2 - 0 = 4
4 + 4 - 1 = 7
7 + 7 - 1 = 13
13 + 13 - 2 = 24
24 + 24 - 2 = 46 ←←←
46 + 46 - 3 = 89

Which equation correctly uses the law of cosines to solve for y? 92 = y2 + 192 – 2(y)(19)cos(41°) y2 = 92 + 192 – 2(y)(19)cos(41°) 92 = y2 + 192 – 2(9)(19)cos(41°) y2 = 92 + 192 – 2(9)(19)cos(41°) PLS HELP!!
Answer:
[tex]Fourth \: option: y^2=9^2+19^2-2(9)(19) cos(41°)[/tex]
[tex]The \: law \: of \: cosines \: to \: solve \: for \: one \: side \: is:[/tex]
[tex]c^2=a^2+b^2-2ab \: cos \: C[/tex]
We must know the other two sides (a and b) and the angle between these sides (angle C, the opposite to the side that we want to determine)
In this case c=y, a=9, b=19, and C=41°, then:
[tex]y^2=9^2+19^2-2(9)(19) \: cos \: (41°)[/tex]
