3. Which phrase best describes the function of the ATP molecule?
1. Carries energy
2. Destroy energy
3. absorbs energy
4. none of the above
Answer:
1.) Carries energy
Step-by-step explanation:
A good summary of an ATP molecule is a molecule that transfers energy between cells... meaning it carries energy from cell to cell. Furthermore, energy cannot be destroyed, and cannot be absorbed, only changed and transformed. This leaves us with two options, (1. Carries energy, and 4. None of the above). Since we already have a basic understanding of what an ATP molecule does, we can confidently determine that the correct answer is that an ATP molecule can best be described as carrying energy.

Step-by-step explanation:
The slope m of a line passing through two points can be calculated using the following formula:
[tex] \sf m = \dfrac{rise}{run} = \dfrac{\Delta y}{\Delta x} = \dfrac{y_2 - y_1}{x_2 - x_1} [/tex]

Let (x₁ , y₁) = (2 , -7)
Let (x₂ , y₂) = (-1 , 6)
Substitute these values into our formula:
[tex] \sf m =\dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{6 - (-7) }{-1 - 2 } = \dfrac{13}{-3}\\ \\ \implies \boxed{\sf m = -\dfrac{13}{3}} [/tex]

To indirectly measure the distance across a river, Nolan stands on one side of the river and uses sight-lines to a landmark on the opposite bank. Nolan draws the diagram below to show the lengths and angles that he measured. Find PRPR, the distance across the river. Round your answer to the nearest foot.
The length of PR to the nearest foot is 198.94 feet
Find the diagram attached
From the diagram, the triangle PRE and POC are similar triangles.
Let PR = x
Based on similarity theorem;
PR/RE = PR+RO/OC
x/135 = (x+140)/230
Cross multiply
230x = 135(x+ 140)
230x = 135x + 18,900
230x - 135x = 18,900
95x = 18900
x =18900/95
x = 198.94
Hence the length of PR to the nearest foot is 198.94 feet

What is volume?In mathematics, volume is the space taken by an object.
Here, given that,
The height of a cylinder is 4 millimeters.=h
The circumference of its base is 10 pi mm=2r*pi
So, we get,
r=5
Volume =pi*r²*h

The angles in a quadrilateral are 103.8° , 77° , 111.4° and p°. Calculate the value of p.
Answer: 67.8°
Step-by-step explanation:
A quadrilateral's interior angles always add up to 360°.
An equality statement can be set up to satisfy this rule:
103.8+77+111.4+p=360
Collect known values
292.2+p=360
Isolate and solve for p
292.2 (-292.2) +p=360 (-292.2)
p=67.8
Answer:
68.6
Step-by-step explanation:
hello sir / mam!
as the opposite sides of quadrilateral should be 180°
111.4+p=180°
p=180-111.4
p=68.6°
therefore the value of p = 68.6°

A student graphed f(x) = x and g(x) = -5f(x) + 2 on the same coordinate grid. Which statement describes how the graphs of f(x) and g(x) are related?
The graph of f(x) is translated 5 units up to create the graph of g(x).
The graph of g(x) is translated 2 units down and is less steep than the graph of f(x).
The graph of f(x) is translated 5 units down to create the graph of g(x).
The graph of g(x) is translated 2 units up and is steeper than the graph of f(x).
Answer:
ME TOO
Step-by-step explanation:
Function transformation involves changing the position of a function.
The relationship between f(x) and g(x) is (d) The graph of g(x) is translated 2 units up and is steeper than the graph of f(x).
The functions are given as:
[tex]\mathbf{f(x) = x}[/tex]
[tex]\mathbf{g(x) = -5f(x) + 2}[/tex]
Substitute x for f(x) in g(x)
[tex]\mathbf{g(x) = -5x + 2}[/tex]
The +2 in [tex]\mathbf{g(x) = -5x + 2}[/tex] means that, g(x) is gotten by translating f(x) up by 2 units.
The -5 in [tex]\mathbf{g(x) = -5x + 2}[/tex] means that, g(x) has a steeper slope.
Hence, the correct option is (d)

Rationalize the denominator.
– 5x4
✓4x +7
The question is asking us to make the denominator a rational function by finding a way to remove the square root without changing the value of the overall function.
We can do this by multiplying the denominator and numerator by the √(4x + 7), since multiplying a root term by that root term = the number being rooted (√x × √x = x).
- 5x⁴ × √(4x + 7) = (-5x⁴)(√(4x + 7))

Josiah skateboards from his house to school 3 miles away. It takes him 36 minutes.
How many minutes will it take Josiah to skateboard to his friend Sebastian’s house, which is 2 1/2
miles from school, if he travels at the same rate that he did from his house to school?
In the box below, type the number that goes in the blank.
Using the speed - distance relationship, the number of minutes it will take Josiah to cover a distance of 2.5 miles is 30 minutes.
Calculating Josiah's speed :
Speed = (distance ÷ time)Speed = (3 ÷ 36) = 0.08333 miles per minute.
Time taken to cover a distance of 2.5 miles :
Time taken = (Distance ÷ Speed)Time taken = (2.5 ÷ 0.08333) = 30 minutes
Therefore, it will take 30 minutes for Josiah to cover a distance of 2.5 Miles

the principle of similar triangles : they have the same angles.
and we do not forget : the sum of all angles in a triangle is always 180 degrees.
a = 180 - 65 - 45 = 70 degrees
b = 65 degrees
c = 70 degrees
b)
same principles.
x = 58 degrees
y = 52 degrees
z = 180 - 58 - 52 = 70 degrees
c)
same principles.
plus the fact that complementary angles around a point on one side of a line are also together 180 degrees.
x = 85 degrees
y = 180 - 40 - 85 = 55 degrees
z = 180 - 85 = 95 degrees
d)
again same principles.
y = 2x (as these 2 angles correspond to each other among the 2 similar triangles).
the angle POQ is again complementary with 87 degrees,
POQ = 180 - 87 = 93 degrees
x + y + 93 = x + 2x + 93 = 180
3x = 87
x = 29 degrees
y = 2x = 2×29 = 58 degrees
