In linear equation , 2,932.25 * ( 1.0316)¹²t = (1)t is value of t .
What are a definition and an example of a linear equation?
A linear equation with one variable is one that contains just one variable. It has the formula Ax + B = 0, with A and B being any two real numbers and x being an uncertain variable with only one possible value. One such linear equation in one variable is 9x + 78 = 18.275000 = 3001 - ( 1 + 0.38/12)⁻¹²t/0.038/12
275000 = 3001 - ( 1 + 0.38/12)⁻¹²t/0.0025
275000 * 0.0025 = 3001 - ( 1 + 0.38/12)⁻¹²t
68.75 = 3001 - ( 1 + 0.38/12)⁻¹²t
3001 - 68.75 = ( 1 + 0.38/12)⁻¹²t
2,932.25 = ( 1 + 0.0316)⁻¹²t
2,932.25 = ( 1.0316)⁻¹²t
2,932.25 = 1/ ( 1.0316)¹²t
2,932.25 * ( 1.0316)¹²t = (1)t

Step-by-step explanation:
rearrange this equation y – 7=3(x−4) into this Ax+By = C
its pretty simple if you think about it :)
firstly, lets multiply the 3 with x - 4
y - 7 = 3x -12
we are going to bring the 3x to the right side to make the arrangement possible
-3x - y = -5 (minus twelve plus seven)

Subtract y's 2 - -4 is
2+4 which is 6, put that on top.
0 - 4 is -4 put it on the bottom.

A group of students is arranging squares into layers to create a project. The first layer has 4 squares. The second layer has 8 squares. Which formula represents an arithmetic explicit formula to determine the number of squares in each layer?
Answers
(d) f(1) = 4 f(n) = 4 + d(n-1) , n>0 is the arithmetic formula to find the number of layers in the project
In the above question it is given that
A project is being created by a group of students by arranging layers.
The first layer is having 4 layers and as we move to the next layers, it is getting 2 times of the number of layers in the first layer.
i,.e f(1) = 4
Number of layers in the second layer = 8 layers
f(2) = 4.2 = 8
Now, we need to find the general arithmetic formula to determine the subsequent n number of layers in the project
As the subsequent layers are getting n times of the first layer, so we'll also find the similar arithmetic formula where addition to the first layer with n times of it is happening
So, after checking all the given options we find, (d) as the appropriate option
f(1) = 4
f(n) = 4 + d(n-1) , n>0
We'll find the number of layers in the 3 layers
Here, n = 3
Putting in the formula, we'll find.
f(3) = 4 + d(3-1)
f(3) = 4 + d(2)
where d(2) = 8 (given)
so, f(3) = 4 + 8 = 12
Hence, f(1) = 4 f(n) = 4 + d(n-1) , n>0 is the arithmetic formula to find the number of layers in the project

A study on students drinking habits wants to determine the true average number of alcoholic drinks all uf graduate students have in a one week period. We know from preliminary studies that the standard deviation is around 1. 8. How many students should be sampled to be within 0. 25 drink of population mean with 95% probability?.
Answers
The number of the students should be sampled to be within 0.25 alcoholic drinks of population mean with 95% probability is 62.
What is termed as the Margin of error?The margin of error measures the degree of uncertainty in the parameter estimates of parameter results.The reliability of a estimates decreases as the margin of sample error increases.α is the result of subtracting one from confidence interval as well as dividing by two.
α = (1 - 0.95) ÷ 2 = 0.25
Find z in the Z-table because z does have a p-value of 1 - α.
As a result, the p-value of z is (1 - 0.025) = 0.975.
Thus, z = 1.96
Now find M as;
M = z × (σ ÷ √n)
In which,
n is the sample size σ = population standard deviation.When M = 1,
The standard deviation, in accordance with the question, is approximately 1.
σ = 1
M = z × (σ ÷ √n)
0. 25 = 1.96 × (1 ÷ √n)
√n = 1.96 × (1 ÷ √n)
Squaring both sides,
(√n)² = ((1.96 × 1) ÷ 0.25)²
n = (7.84)²
n = 61.4656
n ≈ 62
Thus, the number of the students should be sampled to be within 0. 25 alcoholic drink of population mean with 95% probability is 62.

Answers
The x- and y-intercepts of the graph of x+y=18 are; (18, 0) and (0, 18) respectively.
What is the x-intercept of a function?The x-intercept of a function of variable x ( y = f(x) ) form is an intersection fo the x-axis and the curve of the function. The x-intercept for a function y = f(x) is a solution to the equation f(x) = 0 because at that value of x, the function f(x) lies on x-axis, where y is 0. Values of x-intercept for a function f(x) are also called roots or solution of f(x) = 0 equation.
For x intercept, y = 0
x + y = 18
x + 0 = 18
x = 18
Hence, the x-intercept is (18, 0)
For y intercept, x = 0
x + y = 18
0 + y = 18
y = 18

Given that,
Surface area is decreasing at a rate of [tex]7cm^{2}[/tex]/min,
We know that,
Surface Area of a sphere:

dS/dt = - 7cm2/min
our aim is to find rate of decrease of Diameter:
dD/dt =?
Substitute r in the equation with radius = 1/2*Diameter:
r = 1/2D
Take the derivative of the surface area function with respect to time:
d/dt [S = 4 π (1/2D)2]
d/dt [S = 4 π 1/4*D2]
d/dt [S = π *D2]
dS/dt = 2πD*dD/dt
Solve for dD/dt:
dD/dt = dS/dt / 2πD
Substitute, dS/dt = - 7cm2/min and D = 11 cm
dD/dt = dS/dt / 2πD
dD/dt = - 7cm2/min / 2π*11cm
dD/dt = - 7cm2/min / 22π cm
dD/dt = - 7cm / 22π min
dD/dt = - 0.101 cm/min

Surface area: S
