Based on the excerpt above, what was most likely true about this time in the nation’s history? Whaling was the most profitable industry for African Americans. Ships were the primary means of transporting goods for African Americans. African Americans were performing the same duties as others without the same rights. More industries were created by African Americans during this period than any other time in our nation’s history.
The option that's true about this time in the nation’s history is C. African Americans were performing the same duties as others without the same rights.
The excerpt was gotten from Frederick Douglas's speech. From the excerpt, he stated the contributions of African Americans to the United States. They worked in factories, hospitals, etc.
Despite their contributions, they were denied some rights that the whites had. He stated that African Americans were discriminated against even though they performed the same work just like everyone else.

what is the distance between the points (8, 3) and (8, −6)?
Answer:
There is 9 distances between the points (8, 3) and (8, −6)
Explanation:
Use the distance formula to determine the distance between two points.
To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:
[tex]d=\sqrt{(x^{2} - x^{1} )^{2} + (y^{2} - y^1) ^{2}[/tex]
"d" represents the distance and coordinates are expressed as follows: (x, y)
Let's go to the calculations.
[tex]d=\sqrt{(x^{2} - x^{1} )^{2} + (y^{2} - y^1) ^{2}[/tex]
[tex]d =\sqrt{(8-8)^{2}+(-6-3)^{2} }[/tex]

What is geology?The main branch of Earth science, geology, studies how the earth was created, as well as its makeup and the processes that impact it. Natural humanity's field of geology is interested with Earth and other celestial objects, the structures or rocks that make them up, and also the mechanisms that cause these shifts over time.
A deposition is the act of depositing sediment that has been carried by the air, water, seas, or ice. Granules, sand, clay, and salts that have been dissolved in the water can all be used to convey sediment.
Salts could later be accumulated through evaporation or organic action. Traditionally, sedimentary rocks are found in strata known as strata. Younger layers sit on top of older levels in unbroken strata. Therefore, option C is the correct option.

In basketball, hang time is the time that both of your feet are off the ground during a jump. The equation for hang time is t = 2 (StartFraction 2 h Over 32 EndFraction) Superscript one-half , where t is the time in seconds, and h is the height of the jump, in feet. Player 1 had a hang time of 0.9 s. Player 2 had a hang time of 0.8 s. To the nearest inch, how much higher did Player 1 jump than Player 2? in.
Answer:
8in
Explanation:
edge 2020
The amount of height that player 1 jumped higher than player 2 to the nearest inch is; 8 inches
How to substitute values into an equationWe are given the hang time equation as;
t = 2(2h/32)^(½)
Where;
h is height of jump
Hang time of player 1 = 0.9 s
Hang time of player 2 = 0.8 s
Let's make h the subject of the hang time equation to get;
h = 2t²
For player 1;
h1 = 2(0.9)²
h1 = 3.24 ft
Converting to inches gives;
h1 = 38.88 inches
For player 2;
h2 = 2(0.8)²
h2 = 2.55 ft
Converting to inches gives
h2 = 30.72 inches
Difference in jump height = h1 - h2
Difference in jump height = 38.88 - 30.72
Difference in jump height ≈ 8 inches

a ball is thrown straight downward with a speed of 0.80 meters per second. what is the speed of the ball 0.60 seconds after it is released? [ignore air resistance.]
The speed of the ball 0.60 seconds after it is released is 6.8 m/s.
Newton's law of motion is given by:
v = u + gt
where v is the final velocity, u is the initial velocity, g is the acceleration due to gravity and t is the time.
Given that:
u = 0.8 m/s, g = 10 m/s², t = 0.6s. Hence:
v = 0.8 + 10(0.6)
v = 6.8 m/s
Therefore the speed of the ball 0.60 seconds after it is released is 6.8 m/s.

Answer:
B. 960 ft^2
Explanation:
edge says trust me
Based on the calculations, the area of this pentagonal pool that needs to be covered is equal to: B. 960 ft².
Given the following data:
Radius of pool = 20.10 ft.
Side length of pool = 23.62 ft.
How to calculate the area of the pool?Mathematically, the area of a regular pentagon can be calculated by using this formula:
A = ¹/₄√(5(5 + 2√5)a²)
Where:
a is side length.
Substituting the parameters into the formula, we have:
A = ¹/₄√(5(5 + 2√5)23.62²)

a 15.0 kg block is attached to a very light horizontal spring of force constant 575 n/m and is resting on a smooth horizontal table (figure 1). suddenly it is struck by a 3.00 kg stone traveling horizontally at 8.00 m/s to the right, whereupon the stone rebounds at 2.00 m/s horizontally to the left.
The instantaneous velocity of the 15 kg. mass just after collision can be found by the principle of linear momentum.
a) The speed of the 15 kg. just after collision is 2 m/s.
b) The type of collision is inelastic collision
c) The compression of the spring is approximately 0.323 m.
Reasons:
The given parameters are;
Mass of the block attached to the spring, m₁ = 15.0 kg
Force constant of the spring, K = 575 N/m
Mass of the stone that strikes the block, m₂ = 3.00 kg
Speed of the stone, v₂ = 8.00 m/s
Speed with which the stone rebounds, v₃ = 2.00 m/s
a) The total initial momentum = 3 kg. × 8 m/s = 24 kg·m/s
The final momentum, just after collision = 3 × (-2) kg·m/s + 15 kg ×v₁
By conservation of momentum, we have;
24 kg·m/s = 3 × (-2) kg·m/s + 15 kg ×v₁
[tex]v_1 = \dfrac{24 \, kg \cdot m/s + 6 \, kg \cdot m/s}{15 \, kg} = 2 \, m/s[/tex]
The speed of the 15 kg. just after collision, v₁ = 2 m/s.
b) A collision is elastic when the kinetic energy of the collision is conserved
The initial kinetic energy, K.E.₁ = 0.5 × 3 kg. ×(8 m/s)² = 96 J
The sum of the final kinetic energy are;
0.5 × 3 kg. × (2 m/s)² + 0.5 × 15 kg × (2 m/s)² = 36 J
The initial kinetic energy ≠ The final kinetic energy
Therefore, the collision is not elastic
(c) The kinetic energy given by the block = The elastic potential energy gained by the spring
Kinetic energy of the block, K.E. = 0.5 × 15 kg × (2 m/s)² = 30 J
Elastic energy gained by the block = 0.5 × K × x² = 0.5 × 575 N/m × x²
Therefore;
0.5 × 575 N/m × x² = 30 J
[tex]x^2 = \dfrac{30 \, J}{0.5 \times 575 \, N/m} = \dfrac{12}{115} \, m^2[/tex]
[tex]x = 2 \cdot \sqrt{\dfrac{3}{115} } \approx 0.323[/tex]

The polynomial [tex]3y^2 (y 7)^ 2 - 15[/tex] after it has been fully simplified and written in standard form as [tex]4y^4 + 34[/tex].
A polynomial is an expression in mathematics that consists of variables (also known as indeterminates) and coefficients.
It involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. x2 4x + 7 is an example of a polynomial with a single indeterminate x.
A polynomial is a mathematical expression made up of indeterminates and coefficients that only involves the operations of addition, subtraction, multiplication, and positive-integer powers of variables.
To fully simplify and write the polynomial [tex]3y^2(y-7)^2 - 15[/tex] in standard form, we first need to expand the squared binomial:
[tex](y-7)^2 = (y-7)(y-7) = y^2 - 14y + 49[/tex]
Now we can substitute this expression back into the original polynomial and simplify:
[tex]3y^2(y-7)^2 - 15 = 3y^2(y^2 - 14y + 49) - 15\\= 3y^2y^2 - 42y^3 + 147y^2 - 15\\= 3y^4 - 42y^3 + 147y^2 - 15[/tex]
So the fully simplified polynomial, written in standard form, is:
