John was visiting four cities that form a rectangle on a coordinate grid at A(0, 4), B(4, 2), C(1, -4) and D(-3, -2). What is the area of the space that cities enclose? Round your answer to the nearest whole number. Do not include units in your answer.
Answers
Answer:
[tex]Area = 30[/tex]
Step-by-step explanation:
Given
Rectangle coordinates
[tex]A = (0,4)[/tex]
[tex]B = (4,2)[/tex]
[tex]C = (1,-4)[/tex]
[tex]D =(-3,-2)[/tex]
Required
The area of the rectangle
The area is calculated as:
[tex]Area = Length* Width[/tex]
The length of the rectangle will be represented as:
[tex]Length = AB = CD[/tex]
And the width is:
[tex]Width = BC = AD[/tex]
Calculate distance AB using:
[tex]AB = \sqrt{(x_1 - x_2)^2 +(y_1 - y_2)^2 }[/tex]
Where:
[tex]A = (0,4)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]B = (4,2)[/tex] [tex]--- (x_2,y_2)[/tex]
[tex]AB = \sqrt{(0 - 4)^2 +(4 - 2)^2 }[/tex]
[tex]AB = \sqrt{(- 4)^2 +(2)^2 }[/tex]
[tex]AB = \sqrt{16 +4 }[/tex]
[tex]AB = \sqrt{20}[/tex]
Calculate distance BC using:
[tex]BC = \sqrt{(x_1 - x_2)^2 +(y_1 - y_2)^2 }[/tex]
[tex]C = (1,-4)[/tex] [tex]---(x_1,y_1)[/tex]
[tex]B = (4,2)[/tex] [tex]--- (x_2,y_2)[/tex]
[tex]BC = \sqrt{(1 - 4)^2 +(-4 - 2)^2 }[/tex]
[tex]BC = \sqrt{(- 3)^2 +(-6)^2 }[/tex]
[tex]BC = \sqrt{9 +36}[/tex]
[tex]BC = \sqrt{45}[/tex]
So, the area is:
[tex]Area = Length * Width[/tex]
[tex]Area = AB * BC[/tex]
[tex]Area = \sqrt{20} * \sqrt{45}[/tex]
[tex]Area = \sqrt{20 * 45}[/tex]
[tex]Area = \sqrt{900[/tex]
[tex]Area = 30[/tex]

Answers
Answer:
D. 120
Step-by-step explanation:
f(x) = starting value + (x-1) * common difference
This is basically saying that you started with 20 and add 10 dollars every week
When you plug in your values, you get this:
f(x) = 20 + (10-1) * 10
Then, you solve it to get your answer.
f(10) = 20 + (10-1) * 10
f(10) = 20 + 9 * 10
f(10) = 20 + 90
f(10) = 110

Samuel ate
1/2 of the oatmeal cookies and 2/3 of the
sugar cookies for a total of 18 cookies. The number
of oatmeal cookies he ate was six more than the
number of sugar cookies he ate. How many sugar
cookies did he eat?
Answers
Answer:
9 sugar cookies
Step-by-step explanation:
Let the number of sugar cookies be x.
If the number of oatmeal cookies was six more than the number of sugar cookies, then oatmeal cookies can be represented by x + 6.
So, we know that Samuel ate half of the oatmeal cookies and 2/3 of the sugar cookies, for a total of 18 cookies. Let's represent this with an equation.
x + x + 6 = 18
2x + 6 = 18
2x = 12
x = 6
So x represents 6. Recall that he ate 2/3 of the sugar cookies, so 2 parts of sugar cookies is 6.
Therefore, we can do this:
(3/2) x 6 = 9 cookies
This is essentially saying, "I want to find 3 parts if 2 parts is 6 cookies."
He ate 9 sugar cookies.
Can someone plz help me find the missing side using sin or cos and rounding it to the nearest tenth
Answers
Answer:
65.73
Step-by-step explanation:

The transformation of 'f' is represented by 'g'. Write a rule for g. f(x)=\root(3)(x). Then show your check steps.
Answers
Answer:
[tex]g(x)=-2\sqrt[3]x[/tex]
or
[tex]g(x) = -2f(x)[/tex]
Step-by-step explanation:
Given
[tex]f(x) = \sqrt[3]x[/tex]
Required
Write a rule for g(x)
See attachment for grid
From the attachment, we have:
[tex](x_1,y_1) = (-1,2)[/tex]
[tex](x_2,y_2) = (1,-2)[/tex]
We can represent g(x) as:
[tex]g(x) = n * f(x)[/tex]
So, we have:
[tex]g(x) = n * \sqrt[3]x[/tex]
For:
[tex](x_1,y_1) = (-1,2)[/tex]
[tex]2 = n * \sqrt[3]{-1}[/tex]
This gives:
[tex]2 = n * -1[/tex]
Solve for n
[tex]n = \frac{2}{-1}[/tex]
[tex]n = -2[/tex]
To confirm this value of n, we make use of:
[tex](x_2,y_2) = (1,-2)[/tex]
So, we have:
[tex]-2 = n * \sqrt[3]1[/tex]
This gives:
[tex]-2 = n * 1[/tex]
Solve for n
[tex]n = \frac{-2}{1}[/tex]
[tex]n = -2[/tex]
Hence:
[tex]g(x) = n * \sqrt[3]x[/tex]
[tex]g(x)=-2\sqrt[3]x[/tex]
or:
[tex]g(x) = -2f(x)[/tex]
The length of a football field is 120 yards from one and one to the other end zone.

Answer:
To solve, you need to use Pythagorean Theorum
a^2+b^2=c^2
100^2+53.33^2 = c^2
10,000+2844.0889=c^2
12844.1=c^2
square root
= 113 1/3 yards
So it is less than 120 yards

A pen, a marker and pencil have a total length of 48cm. The pen is 1cm shorter than the marker which is 1cm shorter than the pencil. Calculate the length of each
Answers
We know that the sum of these lengths is 48 cm so:
P + Pn + M = 48 (Equation 1)
Now we need to use the relationships of the lengths to find 2 more equations:
Pn = M - 1 (Equation 2)
M = P - 1 (Equation 3)
Now, sub Equations 2 and 3 into the first equation and solve for the value of P, which is 17.
Next, use the value of P to find your M value and then finally use that M value to get your Pn value.
The final answer is: pencil length = 17cm, marker length = 16cm and pen length = 15cm.
