Answer:
It is necessarily true necessary to increase the altitude at same rate
Step-by-step explanation:
According to questions the time take by both the climbers is same where as their distance traveled and velocity is different
Let time taken to complete the journey for both the climbers= t
therefore t = [tex]\frac{d_1}{v_1} = \frac{d_2}{v_2}[/tex] where
[tex]d_1[/tex] and [tex]d_2[/tex] is the distance traveled by climbers
[tex]v_1[/tex] and [tex]v_2[/tex] is the respective velocity of climbers
So, it is necessarily true necessary to increase the altitude at same rate as the time taken depends on the ratio of their respective altitude with velocity
The two climbers arrived at the top of the mountain at the same time hence both climbers increased in altitude at the same rate.
Mountain climbers are people who ascend mountains. Usually, mountain climbers use steep routes. The altitude covered depends on the rate at which the altitude is increased.
Since the two climbers arrived at the top of the mountain at the same time, it then follows that both climbers increased in altitude at the same rate.

Answer: p = 1
Step-by-step explanation:
2/5 + p = 4/5 + 3/5p
-2/5 -2/5
p = 2/5 + 3/5p
-3/5p -3/5p
2/5p = 2/5
Divide both sides by 2/5

Find the slope of the line that passes through each pair of points. (-3, 1 )and (-17, 2)
Answer:
1/-14 or 1 over - 14
Step-by-step explanation:
The equation you need is: y2-y1 over x2-x1
So if you plug it in it becomes 2-1 over -17 -(-3) so 2 - 1 is 1 that's the easy part, 17 - (-3) is the hard part because you can't minus a negative. So it becomes -17+3 which is still -14 because you take the sign of the bigger number. Sorry if it's hard to understand :(

Given:
The graph of an exponential function.
To find:
The function in the form of [tex]f(x)=ab^x[/tex].
Solution:
The general form of an exponential function is
[tex]f(x)=ab^x[/tex] ...(i)
From the given graph it is clear that the function passes through the points (0,4) and (1,7). It means these points will satisfy the function.
For x=0 and f(x)=4,
[tex]4=ab^0[/tex]
[tex]4=a(1)[/tex]
[tex]4=a[/tex]
For x=1 and f(x)=7,
[tex]7=ab^1[/tex]
Putting a=4, we get
[tex]7=4(b)[/tex]
[tex]\dfrac{7}{4}=b[/tex]
Substitute a=4 and [tex]b=\dfrac{7}{4}[/tex] in (i).
[tex]f(x)=4\left(\dfrac{7}{4}\right)^x[/tex]
Therefore, the required exponential function is [tex]f(x)=4\left(\dfrac{7}{4}\right)^x[/tex].

Step-by-step explanation:
Given
[tex]x^4 * (-y)^4[/tex]
Required
Select and equivalent expression
[tex]A.\ (xy)^4[/tex] [tex]B.\ (-xy)^4[/tex] [tex]C.\ -(xy)^4[/tex] [tex]D.\ (x-y)^4[/tex]
[tex]x^4 * (-y)^4[/tex]
Apply law of indices:
[tex]x^4 * (-y)^4 =x^4 * (-y) * (-y) * (-y) * (-y)[/tex]
This gives:
[tex]x^4 * (-y)^4 = x^4 * (y) * (y) * (y) * (y)[/tex]
[tex]x^4 * (-y)^4 =x^4 * y^4[/tex]
x and y have the same exponent; So, they can be expressed as:
[tex]x^4 * (-y)^4 = (x*y)^4[/tex]
[tex]x^4 * (-y)^4 = (xy)^4[/tex]

Suppose you are testing two fertilizers on bamboo plants A and B, which are growing under identical conditions. Plant A is 6 cm tall and growing at a rate of 4 cm per day. Plant B is 10 cm tall and growing at a rate of 2 cm per day.
Answer:
2 days
Step-by-step explanation:
Step one:
let the number of days be x
and the total height be y
Plant A is 6 cm tall and growing at a rate of 4 cm per day.
the total height is
y=6+4x------------1
Plant B is 10 cm tall and growing at a rate of 2 cm per day.
y=10+2x-----------2
Required
time taken for both plants to have the same height
Step two:
equate the two equations to find when the plants will have the same height
6+4x=10+2x
collect like terms
4x-2x=10-6
2x= 4
divide both sides by 2
x= 4/2
x= 2 days

Answer:
x = 7
Step-by-step explanation:
[tex]\frac{10}{8} = \frac{3x-6}{12}[/tex] --> Triangle Similarity Theorem
120 = 8(3x - 6) --> Cross Multiplying
120 = 24x - 48 --> Distributing the 8
24x - 48 + 48 = 120 + 48 --> Adding 48 on both sides
24x = 168 --> Simplifying
24x/24 = 168/24 --> Divide 24 on both sides
x = 7 --> Simplifying

Find the equation for the circle with center (3,−5) and diameter of length 8.
Answer:
(x-3)² + (y+5)² = 16
Step-by-step explanation:
Radius will be half of diameter means that radius = r = 8/2 = 4.
With Center (h,k) the equation of circle is
(x-h)² + (y-k)² = r²
so by putting values answer will be
(x-3)² + (y+5)² = 4²
(x-3)² + (y+5)² = 16
You are filling a 2-liter bottle with liquid from full 80-milliliter containers. How many containers will it take to fill the 2-liter bottle?
Answer:
25 bottles
Step-by-step explanation:
2 litres=2000 milliliters
2000/80=25 (or) 80x25=2000
The amount of containers it will take to fill the 2-liter bottle is 25 containers.
Given the following data:
Volume of bottle = 2 LitersVolume of containers = 80 milliliterTo determine the amount of containers it will take to fill the 2-liter bottle:
In this exercise, you're required to determine the amount of 80-milliliter containers that would be required to fill the 2-liter bottle.
First of all, we would convert the volume in liters to milliliter.
Conversion:
1 Liter = 1000 millimeters
2 Liter = 2000 millimeters
Now, we can find the amount of containers by using the formula:
[tex]Number\;of\;containers = \frac{Volume \;of\;bottle}{Volume \;of\;containers}[/tex]
Substituting the parameters into the formula, we have;
[tex]Number\;of\;containers = \frac{2000}{80}[/tex]
Number of containers = 25 containers

The area of a rectangle is represented by the polynomial x^2+3x-6x-18. What are the length, width, and area of the rectangle if x=12?
Answer:
Length = 15
Width = 6
Area = 90
Step-by-step explanation:
Area of the rectangle = [tex] {x}^{2} + 3x - 6x - 18[/tex]
Lets factorise the polynomial
[tex] = > x(x + 3) - 6(x + 3)[/tex]
[tex] = > (x + 3)(x - 6)[/tex]
We know that Area = Length × Width
Let the length be (x + 3) & width be (x - 6)
Its given in the question that x = 12. So putting the value of x gives ,
Length = [tex]x + 3 = 12 + 3 = 15[/tex]
Width = [tex]x - 6 = 12 - 6 = 6[/tex]
Area = Length × Width = 15 × 6 = 90
