What is 7 and three tenths minus 5 and seven tenths
Answers
Answer:
1.6
Step-by-step explanation:
7 and three tenths = 7 + 3/10 = 7.3
5 and seven tenths = 5 + 7/10 = 5.7
7.3-5.7 = 1.6 or can be written as 1 and six tenths, or 1 and three fifths.
Because the denominators are like we are gonna continue with the operation.
7 3/10 - 5 7/10
= 2 - 4/10
NB. The fraction is negative.

The kinetic energy of the roller coaster is 2000Joules
Given the formula for expressing the velocity of the roller coaster is given as:
\(v = \sqrt{\frac{2k}{1000} }\)
Given the following parameter:
v = 10m/s
Substitute the given parameter into the formula to have:
\(10 = \sqrt{\frac{2k}{1000} }\)
Square both sides of the equation:
\((10)^2=(\frac{2k}{1000} )^2\\100=\frac{4k^2}{1,000,000} \\4k^2=100,000.000\\k^2=\frac{100,000,000}{4} \\k^2=4,000,000\\k=2000Joules\)

Suppose y varies directly with x. When x is 5, y is 15. What is y when x is 12?
Answers
Answer:
y = 36
Step-by-step explanation:
given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
to find k use the condition when x = 5 , y = 15
15 = 5k ( divide both sides by 5 )
3 = k
y = 3x ← equation of variation
when x = 12 , then
y = 3 × 12 = 36

find inverse matrix a = [121,301,021] using adjoint method
Answers
The inverse of the given matrix is:
( 0 1/2 -1/2 )
(-3 1 -3 )
( 1 -1 0 )
What is inverse ?
In linear algebra, the inverse of a square matrix A is another matrix A^{-1}, such that when A and A^{-1} are multiplied together, the result is the identity matrix I. In other words, A^{-1} is the "inverse" of A, and multiplying A by its inverse "undoes" the effect of A.
To find the inverse of a matrix A using the adjoint method, we follow these steps:
Find the determinant of A.
Find the adjugate of A.
Multiply the adjugate of A by 1/det(A) to get the inverse of A.
Let's follow these steps to find the inverse of the given matrix:
Step 1: Find the determinant of A.
We can use the cofactor expansion method to find the determinant:
det(A) = 1(0-2) - 2(3-0) + 1(6-0) = -2 - 6 + 6 = -2
So det(A) = -2.
Step 2: Find the adjugate of A.
The adjugate of A is the transpose of the matrix of cofactors of A. To find the matrix of cofactors, we need to compute the cofactor of each element of A. The cofactor of an element aij is (-1)i+j times the determinant of the submatrix obtained by deleting the row and column containing aij.
The matrix of cofactors is:
( 0 -6 2 )
( 2 2 -2 )
(-2 6 0 )
Taking the transpose of this matrix gives us the adjugate of A:
( 0 2 -2 )
(-6 2 6 )
( 2 -2 0 )
Step 3: Multiply the adjugate of A by 1/det(A).
We have det(A) = -2, so:
A^{-1} = adj(A)/det(A) = (1/-2)( 0 2 -2 ) ( 0 -1 1 )
(-6 2 6 ) = (-3 1 -3)
( 2 -2 0 ) ( 1 -1 0 )
Therefore, the inverse of the given matrix is:
( 0 1/2 -1/2 )
(-3 1 -3 )
( 1 -1 0 )

2) By algebraic transformation

Part C: The transformation that can be used to transform f(x) to g(x) is T(2 - y)×1/2 + x, 0)
Step-by-step explanation:
The coordinates through which the linear function f(x) passes = (1. 3) and (3, 13)
The coordinates through which the linear function g(x) passes = (1, 3) and (1, 13)
The equation for f(x) in slope and intercept form. y = m·x + c is given as follows;
The slope, m = (13 - 3)/(3 - 1) = 5
The equation in point and slope form is y - 3 = 5×(x -1)
y = 5·x - 5 + 3 = 5·x - 3
y = 5·x - 3
The equation for g(x) in slope and intercept form. y = m·x + c is given as follows;
The slope, m = (13 - 3)/(1 - 1) = ∞
∴ The equation in point and slope form is x = 1
Therefore, the two equations meet at the point (1, 2)
The transformation that can be used to transform f(x) to g(x) is T(2 - y)×1/2 + x, 0)
2) Another transformation that can be used is to rotate f(x) by the vertex angle as follows
Vertex angle is 90° - tan⁻¹(m) = 90° - tan⁻¹(5) ≈ 11.3°
Rotation of f(x) by 11.3° about (1, 2) gives g(x)

Determine if it is Exponential growth.
Use the information below to plug in the numbers to the formula. f(x)=a(1+or-r)^x
The value of x for each value of f(x) will lie between two consecutive whole numbers. List the whole numbers.
initial value: 1,000
decay rate: 20%
f(x) = 500
Answers
The value of x that corresponds to f(x) = 500 lies between 0 and 1. The whole numbers between 0 and 1 are 0 and 1, so the answer whole numbers are 0 and 1.
Describe Exponential Growth?Exponential growth is a mathematical concept that describes a process where a quantity grows at an increasing rate proportional to its current value. In other words, the larger the quantity, the faster it grows. This leads to a graph that is characterized by a rapid upward curve that becomes steeper and steeper over time.
Exponential growth is often represented by the equation y = abˣ, where y is the final amount, a is the initial amount, b is the growth factor or base, and x is the time or number of periods.
The function f(x) = a(1 - r)ˣ represents exponential decay, where "a" is the initial value, "r" is the decay rate as a decimal, and "x" is the time variable.
In this case, the initial value is 1,000, and the decay rate is 20%, or 0.20 as a decimal. Therefore, the equation for the function becomes:
f(x) = 1,000(1 - 0.20)ˣ = 800ˣ
To find the whole numbers that correspond to a value of f(x) = 500, we can set the equation equal to 500 and solve for x:
500 = 800ˣ
Taking the natural logarithm of both sides, we have:
ln(500) = ln(800ˣ)
Using the property of logarithms, we can bring down the exponent:
ln(500) = x ln(800)
Solving for x, we divide both sides by ln(800):
x = ln(500) / ln(800) ≈ 0.717
Therefore, the value of x that corresponds to f(x) = 500 lies between 0 and 1. The whole numbers between 0 and 1 are 0 and 1, so the answer is:
The whole numbers are 0 and 1.

Answers
Answer:
D. Symmetric
Step-by-step explanation:
The symmetric property of congruence says, for objects A and B, ...
if A ≅ B, then B ≅ A.

The symmetric property of congruence makes your statement true:
if ΔHXA ≅ ΔRGI, then ΔRGI ≅ ΔHXA
__
Additional comment
The other answer choices involve other properties:
Reflexive -- an object is congruent to itself: ΔHXA ≅ ΔHXA
Commutative -- certain operations allow the order of their operands to be reversed: A +B = B +A for addition; AB = BA (for scalar multiplication)
Transitive -- if A ≅ B and B ≅ C, then A ≅ C.
The property which is illustrated by the given statement is Symmetric property.
What is Reflexive property?Reflexive property states that for any number, c, the number is equal to itself.
Or in case of expressions, a + b = a + b.
Symmetric property states that, for any numbers m and n,
If m = n then n = m.
Transitive property states that, for any numbers m, n and o,
If m = n and n = o, then m = o.
Commutative property is for operation of numbers.
a + b = b + c
Given statement is If, ΔHXA ≅ ΔRGI, then ΔRGI ≅ ΔHXA.
This is symmetric statement.
