The question lacks the required diagram. Find the diagram attached.
From the diagram it can be seen that the line is parallel to the y axis, hence we are going to locate each endpoints on the y axis.
The lower end point is on 2units while the upper end point is on 9 units both on the y axis. The distance between this two points will be the difference between the end point values i.e 9-2 = 7 units.
Hence the distance between the two points shown is 7 units

Find a parametrization of the circle of radius 3 in the xy-plane, centered at (−2,2), oriented counterclockwise. The point (1,2) should correspond to t=0. Use t as the parameter for all of your answers.
Answer:
x = 3*cos(t) - 2
y = 3*sin(t) + 2
Step-by-step explanation:
The equation for a circle of radius 3 and centered at the point ( h , k ) ( -2 , 2 ) is:
( x - h )² + ( y - k )² = r²
In this particular case
h = - 2 k = 2 and r = 3
Then to parametrizace the equation
x = r* cos(t) + h
y = r*sin(t) + k
x = 3*cos(t) + (- 2) ⇒ x = 3*cos(t) - 2
y = 3 *sin(t) + (2) ⇒ y = 3*sin(t) + 2
Now :
when t = 0 x should be 1
Then x = 3 cos(0) - 2 x = 3 - 2 x = 1
and t = 0 y should be 2
Then y = 3*sin(t) + 2 ⇒ y = 3*sin(0) + 2 y = 2

Benn Cornell and Tom Ingulli drove to Chicago a distance of 510 miles, their car gets 23 miles per gallon of gasoline. gasoline costs them $2.59 per gallon. how much did they spend for gasoline on there trip?
Answer:
about $57.42
Step-by-step explanation:
we know how many miles they drove in all (510) and how many miles they can drive per gallon (23)
we need to find out how many gallons of gas they used by dividing the total number of miles they drove (510) by the number of miles per gallon (23) which is about 22.17
510 ÷ 23 = 22.17
we then need to find out how much money they spent on the total number of gallons of gas they purchased by multiplying 22.17 by the amount of money for one gallon of gas ($2.59)
22.17 × 2.59 = $57.42

Hi there! :)
Answer:
[tex]\huge\boxed{y = -7/2x + 4}[/tex]
Given equation:
y = 2/7x - 5
A perpendicular line will have a slope that is the opposite reciprocal, therefore:
2/7 --> -7/2
Substitute the x and y coordinates of the point given to write an equation in slope-intercept form:
(-3) = -7/2(2) + b
Simplify:
-3 = -7 + b
-3 + 7 = b
b = 4
Rewrite the equation:

What is the base 2 equivalent of 6010? * 111101 base 2 111100 base 2 110000 base 2 110100 base 2
Answer:
111100 base 2
Step-by-step explanation:
The conversion of 60 base 10 to base 2
When converting a number from base 10 to base 2, the following steps are taken:
a) The number in base 10 is divided by 2 and the remainder is recorded, this continues until the remainder is less than 2.
b) The remainder from the bottom to the top are arranged so as to get the representation of the number in base 2.
60 base 10 to base 2
60 ÷ 2 = 30 remainder 0
30 ÷ 2 = 15 remainder 0
15 ÷ 2 = 7 remainder 1
7 ÷ 2 = 3 remainder 1
3 ÷ 2 = 1 remainder 1
1 ÷ 2 = 0 remainder 1
The remainder from bottom to top is 111100 base 2.
(60)₁₀ = (111100)₂
If you were 10 years old on
Earth, you would be 41.494 years old
on Mercury. Write the age on Mercury
as a mixed number in simplest form.
Answer:
[tex]41\frac{247}{500}[/tex]
Step-by-step explanation:
41.494
= [tex]41\frac{494}{1000}[/tex]
to simplify the fraction 494 /1000, we have to find and divide both numerator and denominator by the their highest common factor
494 = 2 x 13 x 19
1000 = 2 x 2 x 2 x 5 x 5 x 5
comparing the two, we can see that that the only common factor that both numbers share is 2, hence we divide both numerator and denominator by 2
41 494/1000
= [tex]41\frac{494}{1000}[/tex]
= [tex]41\frac{494/2}{1000/2}[/tex]
= [tex]41\frac{247}{500}[/tex]
A silo is a building shaped like a cylinder used to store grain. The diameter of a particular silo is 6.5 meters, and the height of the silo is 12 meters.
Hey there! I'm happy to help!
To find the volume of a cylinder, you multiply the base by the height.
First, we find the base. The base is a circle. To find the area of a circle, you square the radius and multiply it by pi (we will use 3.14). The radius is half the diameter.
6.5/2=3.25
We square this.
3.25²=10.5625
And multiply by 3.14
10.5625(3.14)=33.16625
Now we multiply this by the height.
33.16625(12)=397.995
Therefore, the volume of this silo is 397.995 cubic meters.

The graph of the line 4x+3y= 12 is translated right 1 unit and down 3 units. What is the equation of the new line?
Answer: y = 7/3 - (4/3)*x
Step-by-step explanation:
First, let's write our line in the notation:
y = f(x)
So we must isolate y in the equation:
4x + 3y = 12
3y = 12 - 4x
y = 12/3 - (4/3)*x = 4 - (4/3)*x
Now, we have two translations, one horizontal and one vertical.
Let's define them in general cases:
Horizontal translation.
When we have y = f(x) and we want to do a horizontal translation of A units to the right (A positive) we have:
y = g(x) = f(x - A)
So we replace our variable x by x - A.
Vertical translation.
When we have y = f(x) and we want to do a horizontal translation of A units up (A positive) we have:
y = g(x) = f(x) + A.
Then in this case we have:
y = f(x) = 4 - (4/3)*x
then, the horizontal translation of 1 unit to the right is:
y = f(x - 1) = 4 - (4/3)*(x - 1)
And the translation of 3 units down (a vertical translation) is:
y = f(x - 1) - 3 = 4 - (4/3)*(x - 1) - 3 = 1 + 4/3 - (4/3)*x
y = 7/3 - (4/3)*x
This equation represents the new line.

A rectangle has a length of 12 yards less than 10 times it’s width. If the area of the rectangle is 880 yards
Answer: The length is 88 yards and the width is 10 yards. Look into the steps for more information.
Step-by-step explanation:
The length is 12 yards less than 10 times the width so we can represent that by the equation L = 10w - 12
And the area is 880 so the width times the length has to equal 880. the width is w and the length is 10w -12
w( 10w -12 ) = 880 solve for w
10w^2 - 12w = 880 subtract 880 from both sides
-880 -880
10w^2 - 12w - 880 = 0 They share the same factors so dive each side by 2
5w^2 - 6w^2 - 440 = 0
a= 5 b = -6 and c=-440
The quadratic formula says that x= -b ± [tex]\sqrt{b^2- 4ac} / 2a[/tex]
x= 6 ±[tex]\sqrt{8836} / 5[/tex]
x= 6 ± 94 /10
x= 100 /10
x = 10
In this case the width is 10 yards.
The length is 12 less than 10 times the width .
So L = 10(10) - 12
L = 100- 12
l = 88
So the length is 88
The required length and width are 229 and 27 yards.
It is required to find the dimension of rectangle.
What is rectangle?A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.
Given:
A=l*w
w=width
10w-12=length

6183=(10w-12)(w)
6183=10[tex]w^{2}[/tex]-14w
9[tex]w^{2}[/tex]-14w-6183=0
By simplify we get,
(9w+229)(w-27)=0
w-27=0
w=27 yards
l=9*27-14=229 yards
Therefore, the required length and width are 229 and 27 yards.
