Answer:
[tex]A_1 = 1500\\A_n = A_{n-1} - 15\%\cdot A_{n-1} + 60[/tex]
Step-by-step explanation:
We just put the task description into the answer :)
The last line can also be shortened to:
[tex]A_n = 85\%\cdot A_{n-1} + 60[/tex]
or
[tex]A_n = 0.85A_{n-1} + 60[/tex]
Izzati, Ai Ling, Rina and Susan share some stamps. Izzati and Ai Ling take 1/4 and 1/8 of the total number of stamps respectively. After that, Rina takes 7/10 of the remaining stamps. Eventually, all the remaining stamps are taken by Susan. If Susan gets 42 stamps, find the total number of stamps.
Answer:
224 stamps
Step-by-step explanation:
Let total number of stamps = x
1/4 + 1/8 = (2 + 1) /8 = 3/8
3/8 of x = 3x/8
Remaining stamp = x - 3x/8 = (8x-3x)/8 = 5x/8
Rina = 7/10 of 5x /8
Rina = 7/10 * 5x /8 = 35x / 80
Remaining stamps = 5x/8 - 35x/80
Remaining stamps = (50x - 35x)/80 = 15x /80
15x / 80 = 42
15x = 80 * 42
15x = 3360
x = 3360 / 15
x = 224 stamps

K
withstanding high blood pressures
Answer: I believe the answer is O passing materials in blood to cells
Step-by-step explanation:
The thin walls of the capillaries allow oxygen and nutrients to pass from the blood into tissues and allow waste products to pass from tissues into the blood.
More info: Capillaries
Capillaries - Enable the actual exchange of water and chemicals between the blood and the tissues. They are the smallest and thinnest of the blood vessels in the body and also the most common. Capillaries connect to arterioles on one end and venules on the other.
The thin walls of the circulatory system allow oxygen and nutrients to pass from the blood into tissues.
What are the Capillaries?Capillaries allow for the movement of water and chemicals between blood and tissues. They are the narrowest and thinnest blood vessels in the body, as well as the most numerous. Capillaries link on one end to arteries and veins and on the other to venules.
The capillaries' thin walls enable oxygen and nutrients to enter from the blood into the tissues and harmful byproducts to pass from the tissue to the blood.
They are the most limited and thinnest blood vessels in the body, as well as the most numerous.
Therefore, the thin walls of the circulatory system allow oxygen and nutrients to pass from the blood into tissues.

Find the measure of \angle G∠G. Round your answer to the nearest tenth (one decimal place).
Hi there!
[tex]\large\boxed{G \approx 55.44^{o}}[/tex]
To solve, we can use right triangle trigonometry.
Recall that:
sin = O/H, cos = A/H, tan = O/A.
For angle G, HF is its OPPOSITE side, and FG is the hypotenuse.
Therefore, we must use sine to evaluate:
sinG = 14 / 17
sin⁻¹ (14/17) = ∠G. Evaluate using a calculator.
∠G ≈ 55.44°

Select the correct answer. When two parallel lines are cut by a transversal, angles A and B are alternate interior angles that each measure 105°. What is the measure of each of the other alternate interior angles?
Answer:
105°Step-by-step explanation:
For two parallel lines cut by a transversal, the alternate interior angles of such line geometry will be equal. Since m<A and m<A are alternate interior angles, hence m<A = m<B
Since one of the angle measures 105degrees, the other angle will also measure 105 degrees, This shows that;
m<A = m<B = 105°

Write an exponential equation that represents the given situation. You invest $1000 and it increases 12% each year. Can you teach me it because i need to show my work, thank you
Answer:
FV= 1,000*(1.12^n)
Step-by-step explanation:
Giving the following information:
Initial investment= $1,000
Increase rate= 12% = 0.12
We need to formulate an exponential equation to show the value in n years.
To calculate the Future Value, we need to use the following formula:
FV= PV*(1+i)^n
Being:
FV= Future Value
PV= Initial Investment
i= increase rate
n= number of periods
FV= 1,000*(1.12^n)
For example, for one year:
FV= 1,000*(1.12^1)
FV= $1,120
For 3 years:
FV= 1,000*(1.12^3)
FV= $1,404.93

The equations y = (- 16t - 2)(t - 1) and y = - 16t ^ 2 + 14t + 2 represent the height in feet of a beach ball thrown by a child as a function of time, tin seconds .
Answer:
0.4375secs
Step-by-step explanation:
Given the height of the beach ball in feet expressed as;
y = -16t^2+14t+2 as the height that represents the height of the ball, we can look for the time taken by the ball to reach its maximum height
At the max height, the velocity is zero i.e dt/dt = 0
dy/dt = -32t + 14
0 = -32t + 14
32t = 14
t = 14/32
t = 0.4375secs
Hence it took the ball 0.4375secs to reach its maximum height

Which of the following statements would be supported by both a communist and a utopian socialist?
A. A classless society can be brought about in Europe without a violent revolution.
B. The gains of the industrial revolution should be shared by all members of society. C. Governments have no right to restrict the actions of businesses or customers.
D. A government should restrict the number of imports and exports to protect its gold reserves.
Answer:
A
Step-by-step explanation:
:)Answer:
B. The gains of the industrial revolution should be shared by all members of society.
Step-by-step explanation:
Communists were opposed to the power that the wealthy bourgeoisie had, who controlled the means of production.
Instead, Communists wanted the proletariat (working class) to control the means of production, in order to create a more even distribution of wealth and power in society.
So, they supported making the Industrial Revolution's benefits shared by society.
Utopian socialists also would support this, as they also supported public ownership of the means of production.
The correct answer is B.

Which solid of revolution is produced by rotating the shape below 360° about the given axis?
Explanation:
When we rotate a rectangle around an axis of symmetry, we end up with a cylinder. Think of a revolving door or a turbine. The flat door moves through 3D space to produce or carve out a 3D cylinder.
This figure is composed of two rectangles, so we'll end up with two cylinders. They will both share the same center, so we'll have a sideways two-layer wedding cake structure when everything is said and done. This points to choice A as the final answer.
The solid of revolution, which is produced by rotating the shape below 360° about the provided axis, is the first one. Option A is correct.
What is solid of revolution?Solid of revolution is the method to obtain the solid figure by the plane. When a plane is revolving about an axis, a solid figure is obtained whose shape is depending on the shape of the plane.
In the problem,
A plane is given which is in the elbow shape. The axis around which it has to revolve is horizontal.The plane is kept at this axis from the base of it.The solid generated with this plane is full rotation, and it will look like the stand of the pole.
Thus, the solid of revolution, which is produced by rotating the shape below 360° about the provided axis, is the first one. Option A is correct.
