Example 5: Taro and Jiro climbed a mountain and hiked back down. At the suminit and at every station along the way back down, they recorded their altitude and the amount of time they had been travelling. Hiking Data Time Traveled (in minutes) Altitude (in meters) 0 3776 3600 29 3 Å 126 3020 2700 179 3 231 2390 Construct a linear function to model the relationship between Taro's and Jiro's altitude in terms of the amount of time they traveled.
Answer:
i
Step-by-step explanation:

Answer:
Let the altitude be represented by y and the time taken by x
so y = 3776 - 6x
What is a Linear Function?A linear function is an algebraic equation with variables with a degree of only 1 and constants and is represented in a straight line form on a graph.
What is Slope?The slope Of a straight line (which represents a linear function) is the tangent of the angle made by the line with the x-axis. For a straight line passing through (x1,y1) and (x2,y2) the slope is given by
m= (y2-y1)/(x2-x1).
How to write an equation of a Straight line?y-y1 = m(x-x1) where y represents y co-ordinate and x represents x- co-ordinate and m is the slope of the line which passes through(x1,y1).
Solving the question with the Above conceptsSo let time in minutes be represented by 'x'
So let altitude in meters be represented by 'y'
So the (x,y) coordinates according to the given data are (0,3776),(88/3,3600),(126,3020),(538/3,2700) and (231,2390).
So for slope which is m = (3600-3776)/(88/3-0) so slope = -6.
So the linear function is: y-3776 = -6(x-0)
6x+y=3776
So the linear function for the altitude in terms of the time they traveled is 6x+y = 3776

HOPE ITS RIGHT!! GIVE BRAINLIEST PLS
Answer:
Y would have to equal 1 over 2(3x+4) in order for this equation to even work properly. 2+1 over 6 would actually equal 1/2y which is basically 3/6y. And since 3 and 6 are like terms 3 divided by 3 is 1 and 6y divided by 3 is 2y

Question 1 (5 points) Find the solution(s) of the quadratic equation X2-25 = 0. x = 25 x= -5.5 x=5 X5
Answer:
x = ± 5
Step-by-step explanation:
x² - 25 = 0 ( add 25 to both sides )
x² = 25 ( take the square root of both sides )
x = ± [tex]\sqrt{25}[/tex] = ± 5
solutions are x = - 5 , x = 5
Harry’s Hi-Fi makes a percentage profit of 25% on each television it sells. If they sell their new range for $2500, how much does each television cost them?
Based on the information given the amount that each elevator cost them is $2,000.
Using this formula
Cost=Sales price/(1+Percentage profit)
Where:
Sales price=$2,500
Percentage profit=25%
Let plug in the formula
Cost=$2,500/(1+.25)
Cost=$2,500/1.25
Cost=$2,000
Inconclusion the amount that each elevator cost them is $2,000.

A friend gave Ms. Morris a gift card for a local car wash. The table shows the linear relationship of how the value left on the card relates to the number of car washes.
Number of car washes, x 0 8 12
Amount left on card ($), y 70 50 40
Part 1 out of 3
Enter an equation that shows the number of dollars left on the card.
The equation that represents this situation is y =
Answer:
Step-by-step explanation:
The table is:
Number of washes denoted by x: 0, 8, 12
Amount left on card denoted by y: 30, 18, 12
a. Write an equation that shows the amount of dollars left on the card
Solution:
18 – 30 divided by 8 – 0 = -12/8
On simplest form is -3/2
The equation is y = -3/2x + 30
b. Explain the meaning of the negative slope above.
As the number of car washes increase, the dollars left on the card decreases.
c. What is the maximum value of x?
0 = -3/2x + 30
2/3 x 3/2 x = 30/1 x 2/3
Cancel 2/3 x 3/2 and reduce 30 by 3 we get 10, 10 x 2
x = 20

Determine whether each expression is equivalent to 64^5t^2 + 3t
Answer:
ALL of the following expressions are NOT equivalent to 64^5t^2+3t
Step-By-Step Explanation:
Khan Academy
To determine whether each expression is equivalent to [tex]64^5t^2 + 3t[/tex], we will simplify each expression by evaluating the calculations.
Expression 1: [tex]64^5t^2 + 3t[/tex]
Expression 2: [tex](4^3)^5t^2 + 3t = 4^(3*5)t^2 + 3t = 4^15t^2 + 3t[/tex]
Expression 3: [tex](8^2)^5t^2 + 3t = 8^(2*5)t^2 + 3t = 8^10t^2 + 3t[/tex]
Expression 4: [tex](2^6)^5t^2 + 3t = 2^(6*5)t^2 + 3t = 2^30t^2 + 3t[/tex]
Expression 5: [tex](8^8)^3t^2 + 3t = 8^(8*3)t^2 + 3t = 8^24t^2 + 3t[/tex]
Expression 6: [tex]64^5t^2 + t + 2t = 64^5t^2 + 3t[/tex]
After evaluating each expression, we can see that all the expressions are equivalent to [tex]64^5t^2 + 3t[/tex]. The calculations show that regardless of the specific values used, the expressions simplify to the same result. Therefore, it can be concluded that all six expressions are equivalent to [tex]64^5t^2 + 3t.[/tex]

So, we can solve this problem by taking 2 steps, Solving and Unit Value.
We'll start off with finding the unit value for 1 cm and how many Newtons we get per one cm.
We can solve for that by dividing both sides by 20 to find the Unit Value.
[tex]\frac{20}{20}=1\\\frac{28}{20}=1.4\\[/tex]
Upon solving, we know that 1.4 is for one unit price. We can then figure out the other blanks by solving it, which we will be doing next.
Solving
To find the first value, we know that the ratio for [tex]I:O[/tex] with I being Input and O being output is 1.4. We know that because in the unit section, we figured the rate out.
We can now use that to find the Newtons, to do that, we must multiply 55 by 1.4.
[tex]55*1.4=77[/tex]
We have found out our first blank which is 77.
We can solve for 140 by dividing it by 1.4 because to get 1 Newton we divide by 1.4 on this table and to get the opposite we have to do the opposite of multiplying; dividing.
We divide 140 by 1.4 and we get 10.
[tex]\frac{140}{1.4}[/tex] = 100
To solve for one, we did that in the beginning, and that would be 1.4

6. Find the perimeter (distance around) each of the foundations in Figure1 and 2.
a. Foundation A perimeter=_________feet
b. Foundation B perimeter=_________feet
Answer:
(a) P = 32.5 feet
(b) P = 108-2x feet
Step-by-step explanation:
Note: Perimeter is the total distance around the border of a shape.
(a)
P = 14' + 27'' + 14' +27'' ; First we have to covert the 27'' (27 inches to feet)
[tex]27*\frac{1}{12} = \frac{27}{12} =\frac{9}{4}[/tex] = 2.25feet
P = 14'+2.25'+14'+2.25'
P = 32.5' = 32.5 feet
(b)
P = 15'+29'+(15'-x')+3'+7'+3'+(7'-x')+29' ; where x is the overlapping distance of the 2 rectangles of Foundation B.
P = 108' -2x'
P = 108-2x feet

Since line KL shows the amount of unwanted material from line NM, subtract the two and divide the result by 2 for the bottom measurement to each triangle
36 - 20 = 16
16/2 = 8
So now since we know our a and our c, we can implement the Pythagorean theorem of a^2 + b^2 = c^2 to find b, or the height of the triangle
8^2 + b^2 = 17^2
64 + b^2 = 289
b^2 = 225
b = 15
Therefore x = 15ft

x
So to start we already know 2 of the 3 angles for the Pythagorean theorem so now we plug them in
360^2 + a^2 = 450^2
129600 + a^2 = 202500
a^2 = 72900
a = 270
So this means that the wires need to be grounded 270m away from the pole

Calculate the density of a metal cube which has 3 cm sides, given that its mass is 428 grams. Convert your answer into kg/m3. Will this cube float on the surface of a liquid of density 1.7 g/cm3? Explain why or why not.
Answer:
Step-by-step explanation:
Volume of the cube is 27 cm^3
Since [tex]density = \dfrac{Mass}{Volume}[/tex]
density = [tex]\dfrac{428 g}{27 cm^3} = 15.85 g/cm^3 > 1.7g/cm^3[/tex]
this will not float on the surface of the liquid.
Convert into kg/m^3
