Find the distance between the points A(10, –9) and B(8, 7). Round your answer to the nearest hundredth. A
Answer:
16.12 units
Step-by-step explanation:
distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(8 - 10)² + (7 + 9)²]
d = √[(-2)² + (16)²]
d = √[4 + 256]
d = √260
d = 16.12

Red kangaroos can reach speeds up to 50 feet per second. Use the linear graph at the left to answer the questions. What is the change in y-values from Point A to Point B? What is the change in x-values from Point A to Point B? What is the rate of change of the linear function? feet per second
Answer:
What is the change in y-values from
Point A to Point B?
50
What is the change in x-values from
Point A to Point B?
1
What is the rate of change of the linear function?
50
feet per second
Step-by-step explanation:
The change in y-values from Point A to Point B is from 0 to 50feet. What is the change in x-values from Point A to Point B is 0 to 1 second. Rate of change of the linear function is given by y = 50x (feet per second).
What is linear function?" Linear function is defined as the algebraic expression which represents the relation between the variables with highest exponent equals to 1."
Formula used
[tex]\frac{y-y_{1} }{x-x_{1} } =\frac{y_{2} -y_{1}}{x_{2} -x_{1}}[/tex]
According to the question,
Given,
Speed of Red kangaroos can reach = 50 feet per second
Number of feet represent by y - axis
Time represent by x-axis
When
[tex]x_{1} = 0 seconds \\\\y_{1} = 0 feet[/tex]
When
[tex]x_{2} = 1 seconds \\\\y_{2} = 50 feet[/tex]
Change in y-values from point A to B is given by [tex](y_{1}, y_{2} ) = (0,50)[/tex]
Change in x-values from point A to B is given by [tex](x_{1}, x_{2} ) = (0,1)[/tex]
Rate of change of the linear function
[tex]\frac{y-0 }{x-0 } =\frac{50-0}{1-0}[/tex]
⇒[tex]y= 50x[/tex]
Hence, the change in y-values from Point A to Point B is from 0 to 50feet. What is the change in x-values from Point A to Point B is 0 to 1 second. Rate of change of the linear function is given by y = 50x (feet per second).

f(x) = x2 -2x & g(x) = 12-8x.
Find f(2) - g(3)
=========================================
Work Shown:
f(x) = x^2 - 2x
f(2) = 2^2 - 2*2 ... replace every x with 2
f(2) = 4 - 4
f(2) = 0
----------------------------
g(x) = 12-8x
g(3) = 12-8*3 ... replace every x with 3
g(3) = 12-24
g(3) = -24
----------------------------
Subtract the results of the previous two sections
f(2) - g(3) = 0 - (-24)
f(2) - g(3) = 0 + 24
f(2) - g(3) = 24

Step-by-step explanation:
Nadia is carrying out mountain climbing.
She started climbing the mountain at an altitude of 19.26 feet below the sea level.
Nadia changed her altitude by climbing a total of 5,437.8 feet from her starting position.
Therefore, Nadia's altitude at the end of her climb can be calculated as follows
= 5,437.8-19.6
= 5,418.2
Hence Maria's altitude at the end of her climb is 5,418.2 feet

distance between (-1,4) and (1,-1
Answer:
√29 units
Step-by-step explanation:
Find the distance between (-1,4) and (1,-1).
We'll use the Pythagorean Theorem:
The horizontal distance between the two points is 1 - (-1), or 2, and the vertical distance is 4 - (-1), or 5.
Thus, the distance squared is 2^2 + 5^2, or 29, and the distance between the two points is therefore
d = √29 units
PLEASE HELP, I DONT UNDERSTAND THIS.....Michael is laying carpet in a perfectly rectangular hall. The area of the hall is 240 square feet, and the width of the hall is 6 feet. How long is the hall?
Answer:
40 feet
Step-by-step explanation:
We know that the area of a rectangle is represented as [tex]lw=a[/tex], where l is the length and w is the width.
We already know the width, and we know the area, so we can plug these values into the equation.
[tex]l\cdot 6 = 240[/tex]
Our goal is to now isolate the variable l, and to do this we can divide both sides by 6.
[tex](l\cdot6) \div6 = 240\div6\\\\l = 40[/tex]
Hope this helped!
Answer:
l=a/w
Step-by-step explanation:
Length equals area divided by width.
A 2-column table with 4 rows. Column 1 is labeled x with entries 1, 2, 4, 5. Column 2 is labeled y with entries 15, 30, 60, 75. Does this table represent a proportional relationship? 1,15 2,30 4,60 5,75 please answer this question quickly please and thank you
Answer:
The table represents a proportional relationship
Step-by-step explanation:
Given
x ------ y
1 ------- 15
2 --------30
4 ---------60
5 -------- 75
Required
Determine if the table shows a proportional relationship
To check this, we make use of the following formula;
[tex]k = \frac{y}{x}[/tex]
Where k is the proportionality constant
When x = 1, y = 15
[tex]k = \frac{15}{1} = 15[/tex]
When x = 2, y = 30
[tex]k = \frac{30}{2} = 15[/tex]
When x = 4, y = 60
[tex]k = \frac{60}{4} = 15[/tex]
When x = 5, y = 75
[tex]k = \frac{75}{5} = 15[/tex]
Since the value of k for all values of x and y is the same; i.e. 15
Then, the table represents a proportional relationship

Asia contains both the highest and lowest known points on earth. Mt. Everest is a little over 29,000 feet above sea level, and the shore of the Dead Sea is about 1,370 feet below sea level. What is the approximate difference in elevation between the two points?
27,630 feet
28,370 feet
29,370 feet
30,370 feet
Answer:
30,370 feet
Step-by-step explanation:
The difference in elevations between two points will be 30370 feet.
It is given that Mt. Everest is 29000 feet above sea level and the shore of dead sea is 1370 feet below the sea level.
We have to find out the difference in elevation between the two points.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.
As per the question ;
Height of Mt. Everest from sea level = 29000 ft. above
Height of shore of dead sea from sea level = 1370 feet below
As these both are in opposite directions , i.e., one above sea level and other below sea level , we should add both of these to find the difference in elevations between these two points.
i.e.,
The difference in elevations between two points will be ;
= 29000 + 1370
= 30370 feet
Thus , the difference in elevations between two points will be 30370 feet.

smith will run out by week 2
Answer:
After 17 weeks
Step-by-step explanation:
We can create a system of equations for this problem, where y is the total amount of money in their banks and x is the amount of weeks passed.
Mr. Smith's equation will be [tex]y = 12x+21[/tex].
Mr. Brown's equation will be [tex]y = 10x+55[/tex].
We can now solve for x by using substitution.
Let's substitute Mr. Brown's equation into Mr. Smith's equation.
This get us [tex]10x + 55 = 12x + 21[/tex].
We can now solve for x.
Let's subtract 12x from both sides:
[tex]-2x + 55 = 21[/tex]
And now let's subtract 21 from both sides:
[tex]-2x+34=0[/tex]
Now we subtract 34 from both sides:
[tex]-2x=-34[/tex]
And divide both sides by -2.
[tex]x=17[/tex]

Step-by-step explanation:
hi the answer is x= 3/5
i have added 2 methods of solving it in the above picture. ask me if you have any questions
Answer:
x = 3/5
Step-by-step explanation:
This equation can be solved with algebraic techniques. We will simplify the equation by combining like terms and then use algebraic techniques in order to solve for x.
2(x - 4) + 2x = -6x - 2 Use the distributive property.
2x - 8 + 2x = -6x - 2 Combine like terms (variable terms first).
4x - 8 = -6x - 2 Add 6x to both sides of the equation.
10x - 8 = -2 Add 8 to both sides of the equation.
10x = 6 Divide by 10 on both sides of the equation.
x = 6/10 Simplify the fraction.
x = 3/5

See the attached chart. The midpoint, M, has 8 units down on the Y axis. So the other half will also have 8 units after that point M. This is also true for the X axis.
Just make the difference between points T and M. For M and S they are the same quantities.
(0; 3) and (1; -5)
X: 1 - 0 = 1 (one unit until mid point)
Y: - 5 - 3 = - 8 (8 units until mid point)

S(W; Z) M = center point coordinate value
W = M + 1 ⇒ W = 1 + 1 = 2
