Answer:
[tex] \underline{\boxed{x = 42}}[/tex]
Step-by-step explanation:
[tex] {70}^{2} = {x}^{2} + {56}^{2} \\ {x}^{2} = {70}^{2} - {56}^{2} \\ x = \sqrt{( {70}^{2} - {56}^{2} )} \\x = \sqrt{(4,900 -3,136) } \\ x = \sqrt{1,764} \\ x = 42[/tex]

The town librarian bought a combination of new-release movies on DVD for $20 and classic movies on DVD for $8. Let
x represent the number of new releases, and let y represent the number of classics. If the librarian had a budget of
$500 and wanted to purchase as many DVDs as possible, which values of x and y could represent the number of
new-release and classic movies bought?
O x = 8, y = 45
O x = 10, y = 22
O x= 16, y = 22
O x = 18, y = 18

Answer:
Step-by-step explanation:
he is right i got a 100 in the test
The number of new-release movies on DVD is 16 and the number of classic movies on DVD is 22 option third x= 16, y = 22 is correct.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
New-release movies on DVD for $20 and classic movies on DVD for $8
x - the number of new releases,
y - he number of classics.
20x + 8y = 500
or
5x + 2y = 125
Using trial and error method:
Plug x = 16 and y = 22
5(16) + 2(22) = 125
= 80 + 44
= 124
Nearest to 125
Thus, the number of new-release movies on DVD is 16 and the number of classic movies on DVD is 22 option third x= 16, y = 22 is correct.

Find the volume of the solid whose base is the region Ix I Iy I < 1 and whose vertical cross sections perpendicular to the y-axis are semicir- cles (with diameter along the base) g
Answers
Answer:
volume of the solid = [tex]\frac{\pi }{3}[/tex]
Step-by-step explanation:
As given , the region : |x| + |y| [tex]\leq[/tex] 1
when y [tex]\geq[/tex] 0 ,
|x| + y = 1
⇒|x| = 1 - y
when y ≤ 0 ,
|x| - y = 1
⇒|x| = 1 + y
The given region is the rectangle with sides (0, 5) , (0, -5), (5, 0), (-5, 0)
As given , the vertical cross section are semicircle
As we know that the area of semi circle = [tex]\frac{1}{2}[/tex][tex]\pi x^{2}[/tex]
Now,
Volume = [tex]\int\limits^0_-1 {\frac{\pi }{2} (1+y)^{2} } \, dy[/tex] + [tex]\int\limits^1_0 {\frac{\pi }{2} (1-y)^{2} } \, dy[/tex]
= [tex]\frac{\pi }{2} (\frac{(1+y)^{3} }{3} )[/tex] - [tex]\frac{\pi }{2} (\frac{(1-y)^{3} }{3} )[/tex]
= [tex]\frac{\pi }{6}[/tex][1-0] - [tex]\frac{\pi }{6}[/tex][0-1]
= [tex]\frac{\pi }{6} + \frac{\pi }{6} = 2\frac{\pi }{6} = \frac{\pi }{3}[/tex]
⇒volume of the solid = [tex]\frac{\pi }{3}[/tex]
Volume of the solid is the value of the capacity of the object that can be hold by it. Thus the value of the volume of the given solid is,
[tex]V=\dfrac{\pi}{3} [/tex]
Given information-The vertical cross sections of the solid is perpendicular to the y-axis.
The region of the base is,
[tex]|x|+ |y|\leq 1[/tex]
VolumeVolume of the solid is the value of the capacity of the object that can be hold by it.
When the value of the variable y is greater than or equal to zero than the value of the x is,
[tex]|x|=1-y[/tex]
When the value of the variable y is less than or equal to zero than the value of the x is,
[tex]|x|=1+y[/tex].
Given inequality makes a square with the corners (1,0), (0,1),(-1,0),(0,-1).
Now the limit for the given solid is between 0 to 1 and area is equal to the semicircle which is,
[tex]A=\dfrac{\pi x^2}{2} [/tex]
Thus the volume of the solid whose area bounded by the region 1 to -1 and vertical cross section is semicircle can be given as,
[tex]V=\int\limits^1_0 {\dfrac{\pi x^2}{2} } \, dx [/tex]
[tex]V=\dfrac{\pi}{2} [\;\;\int\limits^1_0 {(1+y)^2} \, dy +\int\limits^1_0 {(1-y)^2} \, dy ][/tex]
[tex]V=\dfrac{\pi}{2} [\;\;\dfrac{\int\limits^1_0 {(1+y)^3}}{3} \, +\dfrac{\int\limits^1_0 {(1-y)^3} \, }{3} ][/tex]
[tex]V=\dfrac{\pi}{6} [\;\;\ {(1-0)^3} \, +{(0-1)^3} \, ][/tex]
[tex]V=\dfrac{\pi}{3} [/tex]
Thus the value of the volume of the given solid is,
[tex]V=\dfrac{\pi}{3} [/tex]

if tñ=2ñ+3, find S10
Answers
Answer:
[tex]S_{10}=280[/tex]
Step-by-step explanation:
Given that,
[tex]t_n=2n+3[/tex] ...(1)
We need to find the value of [tex]S_{10}[/tex].
Put n = 1 to find the first term.
[tex]t_1=2(1)+3=5[/tex]
Put n = 2 to find the second term.
[tex]t_2=2(2)+3=7[/tex]
Put n = 3 to find the third term.
[tex]t_3=2(3)+3=9[/tex]
Put n = 10 to find the tenth term.
[tex]t_{10}=2(10)+3=23[/tex]
It means we need to find the sum of 5,7,9,.....,23.
The formula for the sum of n terms is given by :
[tex]S_=\dfrac{n}{2}(a+a_n)[/tex]
We have, n = 10, a = 5 and [tex]a_n=23[/tex]
So,
[tex]S=\dfrac{10}{2}(5+23)\\\\S_{10}=10\times 28\\\\=280[/tex]
So, the value of [tex]S_{10}[/tex] is equal to 280.

Explanation:
VX is a midsegment and it is half as long compared to the parallel side UY. This means UY is twice as long compared to VX
UY = 2*(VX)
s = 2*(s-37)
s = 2s - 74
s-2s = -74
-s = -74
s = 74
This makes UY be 74 units long
So VX = (1/2)*UY = 0.5*74 = 37
Answer:
37
Step-by-step explanation:
The midsegment theorem states that a midsegment is half the measure of the line it is parallel to (the base). So VX is 1/2 of UY. So:
2(s-37)=s
2s-74=s
s=74
VX= 37
