The average rate of change in m/s of the height of the rock between 2 and 4 seconds is -4.9.
What is average?The average is defined as the mean value of the given data which is equal to the ratio of the sum of the data value to the total number of units present in the data.
Average = the sum of the data value / the total number of units
The rock's height from the ground in meters, h(t), is modeled by the formula h(t) = -4.9ť + 100,
where t is the time in seconds.
At t = 2 seconds
h(t) = -4.9ť + 100
h(t) = -4.9(2) + 100
= 90.2
At t = 4 seconds
h(t) = -4.9ť + 100
h(t) = -4.9(4) + 100
= 80.4
The average rate of change in m/s of the height of the rock is between 2 and 4 seconds
= 80.4 - 90.2 / 2
= - 4.9
Thus, the correct option is A.

What is a triangle?A triangle is a two - dimensional figure with three sides and three angles.
The sum of the angles of the triangle is equal to 180 degrees.
∠A + ∠B + ∠C = 180°
Given is a right angled triangle as shown in the image.
There are six major trigonometric functions as -
Sine(x)Cosine(x)Tangent(x)Cotangent(x)Secant(x)Cosecant(x)We can write the relation between them as -
Sine = 1/cosecantCosine = 1/secantTangent = 1/CotangentWe can write the value of the unknown variable {x} as -
sin(57°) = x/15
sin(57°) = x/15
x = 15 sin(57°)
x = 15 x 0.838
x = 12.6
So, we can conclude that the value of the unknown variable is 12.6.
Therefore, the value of the unknown variable is 12.6.

a heater is turned on in a cold room the scatterplot shows the relationship between the length of time since the heater was on in the temperature of the room the y-intercept of the estimated line of best fit is at (0, b). enter the approximate slope of the estimated line of best fit in the second response box
Answers
Answer:
A estimation of the slope is (1/2) °C/min
Step-by-step explanation:
A linear relationship can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the line passes through the points (x₁, y₁) and (x₂, y₂), then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
Then we just need to look at the graph and find two points that belong to the graphed line (not the points) and estimate the slope
We can see that the line passes near the points (14 min, 14°C) and (18 min, 16°C)
Then the slope is:
a = (16°C - 14°C)/(18 min - 14 min) = (2°C)/(4 min) = (1/2) °C/min

%
Answers
Answer:
0.01 %
Step-by-step explanation:
The given model is;
y = a (0.5)^t/5730
Which is;
y = a(2^-1(t/5730)
Then;
y = a (2^-1/5730)^t
y = a(0.999879)^t
Hence;
Given that the general model is;
y(x)= a(1-r)^x
Where r is the rate percent
Since 1-r =0.999879
r = 0.00012096
y = a(1 - 0.00012096)^t
So;
r= 0.00012096* 100 = 0.01 %

A hot air balloon holds 2,200 cubic meters of helium. The density of helium is 0.1785 kilograms per cubic meter. How many kilograms of helium does the balloon contain, rounded to the nearest tenth of a kilogram? (5 points) 2,199.8 kg 11,195.9 kg 392.7 kg 2,200.2 kg
Answers
392.7
To get the answer multiply Density * Volume
Mass = 0.1785 * 2200
Mass = 392.7
The amount of helium present in the hot air balloon = 392.7 kg
Formula to calculate density:d = mass / volume
Given: volume of helium present in a hot air balloon = 2200 cubic meters
density of helium = 0.1785 kilograms per cubic meter
Let, m represents the amount of helium present in the balloon.
Using the formula of density,
density of helium = mass of helium / volume of helium
⇒ 0.1785 = m / 2200
⇒ m = 0.1785 × 2200
⇒ m = 392.7 kg
Therefore, option (c) is the correct answer.

Answer:
1996 and 2000
Step-by-step explanation:
Since P (the population) is represented in thousands, 8000 will be represented by 8.
Plug in 8 as P and solve for t:
P = 2|t - 8| + 4
8 = 2|t - 8| + 4
4 = 2|t - 8|
2 = |t - 8|
Separate this into 2 possible cases:
2 = t - 8 and -2 = t - 8
Solve:
2 = t - 8
10 = t
-2 = t - 8
6 = t
So, the answers are 6 and 10.

The measure of ∠4 is 20° when ∠2 is 70˚
What is Angle?An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
An angle is the figure formed by two rays,
The given angle ∠2 = 70°
Complementary angles : A Pair of angles whose sum is 90°
So, Let the complement of ∠A be x
So, ∠2+∠4 = 90°
70°+∠4 = 90°
∠4= 20°
