find the missing part using the pythagorean theorem and find the area.
Answer:
Area=24 units²
Step-by-step explanation:
[tex]x^2 +6^2=10^2[/tex]
[tex]x^2 +36=100[/tex]
[tex]x^2=64[/tex]
[tex]x=8[/tex]
[tex]A=\frac{8*6}{2}[/tex]
[tex]A=\frac{48}{2}[/tex]
[tex]A=24[/tex]

Can you slove this 6=2(y+2)
Answer:
y=1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6=2(y+2)
6=(2)(y)+(2)(2)(Distribute)
6=2y+4
Step 2: Flip the equation.
2y+4=6
Step 3: Subtract 4 from both sides.
2y+4−4=6−4
2y=2
Step 4: Divide both sides by 2.
2y/2 2/2

Step-by-step explanation:
An observer standing on the southern bank of a river sees a tree that is much more than 100 feet downstream on the northern bank of the river. The angle formed by the southern bank and the line from the observer to the tree is 15 ∘. After walking 100 feet downstream, the observer measures the angle formed by the southern bank and the line to the same tree to be 25 ∘. Find the width of the river. (can you show the work please)(also the drawing please)
Answer:
[tex]63\ \text{ft}[/tex]
Step-by-step explanation:
The distances are shown in the figure
[tex]\tan25^{\circ}=\dfrac{p}{b}\\\Rightarrow p=b\tan25^{\circ}[/tex]
[tex]\tan15^{\circ}=\dfrac{p}{b+100}\\\Rightarrow p=b\tan15^{\circ}+100\tan15^{\circ}\\\Rightarrow b\tan25^{\circ}=b\tan15^{\circ}+100\tan15^{\circ}\\\Rightarrow b=\dfrac{100\tan15^{\circ}}{\tan25^{\circ}-\tan15^{\circ}}\\\Rightarrow b=135.08\ \text{ft}[/tex]
[tex]p=b\tan25^{\circ}=135.08\times\tan25^{\circ}\\\Rightarrow p=62.99\approx 63\ \text{ft}[/tex]
The width of the river is [tex]63\ \text{ft}[/tex].

Write as an algebraic expression: Five times
the difference of the cube of y and the
square of x
A. 5y3 + 5x2
B. (5y)3 - (5x)2
C. 5(y3 - x2)
D. (5y - 5x)^6
Given:
The statement is "Five times the difference of the cube of y and the square of x".
To find:
The algebraic expression for the given statement.
Solution:
We know that,
Cube = Power 3
Square = Power 2
Difference = Minus (-)
Times = Multiplication (×)
Now,
Cube of y = [tex]y^3[/tex]
Square of x = [tex]x^2[/tex]
Difference of the cube of y and the square of x = [tex]y^3-x^2[/tex]
Five times the difference of the cube of y and the square of x is:
Required expression = [tex]5(y^3-x^2)[/tex]
Therefore, the correct option is C. The required algebraic expression for the given statement is [tex]5(y^3-x^2)[/tex].
A scatter plot with a line is shown below.
Graph shows numbers from 0 to 10 at increments of 1 on the x axis and number s from 0 to 15 at increments of 1 on the y axis. Scatter plot shows ordered pairs 0, 1 and 1, 1 and 2, 3 and 3, 5 and 4, 6 and 5, 7 and 6, 7 and 7, 8 and 8, 9 and 9, 11 and 10, 15. A line joins ordered pairs 0, 1 and 8, 15.
Which statement is most likely correct about the line?
It can be the line of best fit because it is closest to most data points.
It can be the line of best fit because it passes through all the scatter points.
It cannot be the line of best fit because it is not closest to most of the points.
It cannot be the line of best fit because it does not show positive association.

in the year 2001, a person bought a new car for $22000. for each consecutive year after that, the value of the car depreciated by 5%. how much would the car be worth in the year 2005, to the nearest hundred dollars
Answer:
To the nearest hundred dollars, the car will be worth $17,900 by 2005
Step-by-step explanation:
Firstly, we need to write the depreciation equation
We have this as:
V = I(1 - r)^t
V is the present value which is what we want to calculate
I is the initial value, the amount the cad was bought which is $22,000
r is the rate of change which is 5% = 5/100 = 0.05
t is the time difference which is 2005-2001 = 4
Substituting all these into the depreciation equation, we have it that
V = 22,000(1 -0.05)^4
V = $17,919.1375
To the nearest hundred dollars, that would be;
$17,900

Talia bought a home for her pet turtle the rectangular tank is 3 feet long. 1 foot wide and 2 feet high. What is the volume?
Answer:
Volume of rectangular tank = 6 cubic feet
Step-by-step explanation:
Length of the rectangular tank = 3 feet
Width of the tank = 1 feet
And height of the rectangular tank = 2 feet
Since, tank is in the shape of a cuboid,
Volume of a cuboid = Length × Width × height
= 3 × 1 × 2
= 6 cubic feet
Therefore, volume of the rectangular tank will be 6 cubic feet.
