Mr stoves is investing $1500 on a bank account that would give him 3. 7% compounded monthly. What would be his final balance after 10 years?
Mr stove's final balance after 10 years if he invested 1500 on a bank account that would give him 3. 7% compounded monthly is $2,170.37
What would be his final balance after 10 years?A = P(1 + r/n)^nt
Where
P = $1500
r = 3.7% = 0.037
n = monthly = 12
t = 10 years
So,
A = P(1 + r/n)^nt
A = 1,500.00(1 + 0.037/12)^(12×10)
A = 1,500.00(1 + 0.0030833333333333)¹²⁰
A = $2,170.37

DefineT:R2→R2byT(x)=T−([x1x2])=[3x1−−2x22x2]- a) Letu=[u1u2]andv=[v1v2]be two vectors inR2and let c be any scalar. Prove thatTis a linear transformation. - b) Find the standard matrixAofT. - c) Is T one-to-one? Prove your answer using the matrix A.
a)T(u) + T(v) T is a linear transformation
b)[3 -2 ; 2 0]
c)T is one-to-one.
a) To prove that T is a linear transformation, we need to show that it satisfies two conditions.
1. Additivity: T(u + v) = T(u) + T(v)
Let u = [u1, u2] and v = [v1, v2], then
T(u + v) = T([u1 + v1, u2 + v2]) = [3(u1 + v1) - 2(u2 + v2), 2(u2 + v2)]
= [3u1 - 2u2 + 3v1 - 2v2, 2u2 + 2v2]
= [3u1 - 2u2, 2u2] + [3v1 - 2v2, 2v2]
= T(u) + T(v)
2. Homogeneity: T(cu) = cT(u)
Let u = [u1, u2] and c be any scalar, then
T(cu) = T([cu1, cu2]) = [3cu1 - 2cu2, 2cu2] = c[3u1 - 2u2, 2u2]
= cT(u)
Therefore, T satisfies both conditions, and is a linear transformation.
b) The standard matrix of T is the matrix A = [3 -2 ; 2 0]
c) To determine whether T is one-to-one, we look at the matrix A. Since the matrix A has a non-zero determinant, which is equal to -4, then T is one-to-one.

Question 10 of 10 6 st Answer here 5 E Given the two similar triangles above, what is the measure of side DE?
Answer:
DE = 3
Step-by-step explanation:
What is a scale factor?A scale factor consists of two or more shapes who look the same but have different scales or measures. A scale factor of [tex]\frac{1}{2}[/tex] means that the new shape is half the size of the original.
To solve for a missing length, we can use this expression:
[tex]a^{2} +b^{2} =c^{2}[/tex]Inserting our numbers into the expression:
[tex]8^{2}+ b^{2} =10^{2}[/tex][tex]64 + b^{2} = 100[/tex]Subtract 64 from each side:
[tex](64 - 64) + b^{2} =(100-64)[/tex][tex]b^{2} =36[/tex][tex]\sqrt{36} =6[/tex]Therefore, the missing side length is 6.
Looking at the side CB, it is 10 units long. If the new shape is 5 units long, that means that the scale factor from shape 1 to 2 is [tex]\frac{1}{2}[/tex], meaning it is half its size. If the new shape is half its size, we can use this expression to solve for the missing length:
6 × [tex]\frac{1}{2}[/tex] or 6 ÷ 2 = 3Therefore, the measure of DE is 3.

Give an example of a linear function that has a minimum value but no maximum value. Specify the domain and whether the function is increasing or decreasing.
Select all linear functions with a minimum value but no maximum value.
The decreasing function f(x)=10−3x over the domain x≤9 has a minimum value but no maximum value .
The decreasing function f(x)=5x−1 over the domain x≥−7 has a minimum value but no maximum value.
The increasing function f(x)=2x+5 over the domain x≥ 5has a minimum value but no maximum value .
The increasing function f(x)=7−2x over the domain x≥10 has a minimum value but no maximum value .
The two linear functions that have a minimum value but no maximum value are:
f(x) = 10 - 3x over the domain x ≤ 9
f(x) = 5x - 1 over the domain x ≥ -7
Determining linear functions that have minimum value but no maximum valueFrom the question, we are to determine the linear function that have minimum value but no maximum value
The decreasing function f(x) = 10 - 3x over the domain x ≤ 9 has a minimum value but no maximum value.
Domain: x ≤ 9
This function is decreasing since the slope is negative.
The minimum value occurs at x = 9, where f(9) = 10 - 3(9) = -17.
Since the slope is negative, the function continues to decrease without bound as x approaches negative infinity.
The decreasing function f(x) = 5x - 1 over the domain x ≥ -7 has a minimum value but no maximum value.
Domain: x ≥ -7
This function is increasing since the slope is positive.
The minimum value occurs at x = -7, where f(-7) = 5(-7) - 1 = -36.
Since the slope is positive, the function continues to increase without bound as x approaches positive infinity.
Hence, the functions are:
f(x) = 10 - 3x over the domain x ≤ 9
f(x) = 5x - 1 over the domain x ≥ -7

In 2002, the population of a state was 6.7 million people and was growing at a rate of about 0.32% per year. At this growth rate, the function f (x) = 6.7(1.0032)x gives the population, in millions x years after 2002. Using this model, find the year when the population reaches 7 million people. Round your answer to the nearest whole number.
The population will reach 7 million people approximately 21.67 years after 2002. Rounding to the nearest whole number, this corresponds to the year 2024.
The year when the population reaches 7 million can be determined using the population model given, f(x) = 6.7(1.0032)x, where x is the number of years following 2002.
When we solve for x while setting f(x) equal to 7, we obtain:
[tex]7 = 6.7(1.0032)^x[/tex]
By multiplying both sides by 6.7, we obtain:
[tex]1.04478 = 1.0032^x[/tex]
When we take the natural logarithm of both sides, we obtain:
ln(1.04478) = x * ln (1.0032)
After finding x, we obtain:
x = ln(1.04478) / ln (1.0032)
x ≈ 21.67
Hence, approximately 21.67 years after 2002, the population will reach 7 million. This corresponds to the year 2024 when rounded to the next whole number.

And y = 60° + 40° = 100°
What is an equilateral triangle?An equilateral triangle in geometry is a triangle with equally long sides. The three angles opposite the three equal sides are equal in size because the three sides are equal. As a result, with each angle measuring 60 degrees, it is sometimes referred to as an equiangular triangle. Equilateral triangles have the same area, perimeter, and height formula as other kinds of triangles.
An equilateral triangle has a predictable shape. By combining the words "Equi" (which means equal) and "Lateral," which refers to sides, the word "Equilateral" is created. Due to the equality of its sides, an equilateral triangle is also known as a regular polygon or regular triangle.
from the question:
In an equilateral triangle,
Each angle = 60°

Babe and Ruth are 675 miles apart and headed straight toward each
other. If Babe is traveling at 40 mph and Ruth is traveling at 35
mph, it will take 9 hours before they meet.
To determine the time it will take for Babe and Ruth to meet, we need to use the formula:
time = distance / rate
Since they are traveling towards each other, we can add their speeds to get the combined speed at which they are approaching each other.
combined speed = Babe's speed + Ruth's speed
combined speed = 40 mph + 35 mph
combined speed = 75 mph
Now we can plug in the values we have into the formula:
time = distance / combined speed
time = 675 miles / 75 mph
time = 9 hours

The equation which represents exponential growth is y = (1.2)* and equation which represents exponential decay is y = (.71)*, y = 0(6.3)* represents a constant function.
What is exponential growth or decay function?Consider the function:
[tex]y = a(1\pm r)^m[/tex]
where m is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is plus sign, then there is exponential growth happening by r fraction or 100r %
If there is negative sign, then there is exponential decay happening by r fraction or 100r %
We are given that;
c. y = (1.2)*
d. y = 0(6.3)*
e. y = (.71)*
a.) The equation and graph that show exponential growth is y = (1.2)x. This is because the base of the exponent (1.2) is greater than 1, so as x increases, the value of y increases at an increasing rate. The graph of y = (1.2)x is an upward-curving curve that gets steeper as x increases.
b.) The equation and graph that show exponential decay is y = (0.71)x. This is because the base of the exponent (0.71) is between 0 and 1, so as x increases, the value of y decreases at a decreasing rate. The graph of y = (0.71)x is a downward-curving curve that flattens out as x increases.
Therefore, exponential growth shows y = (1.2)* whereas y = (.71)* show exponential decay.

Consider the polynomial P(x)=kx^(3)-4x^(2)+x+4. Find the value of k such that the remainder is -6 when P(x) is divided by x+1. k
The value of k that makes the remainder of the polynomial equal to -6 when divided by x + 1 is k = 5.
To find the value of k that makes the remainder of the polynomial P(x) = kx3 - 4x2 + x + 4 equal to -6 when divided by x + 1, we can use the Remainder Theorem. The Remainder Theorem states that if a polynomial P(x) is divided by x - a, the remainder is P(a).
In this case, we are dividing by x + 1, so we can rewrite this as x - (-1). Therefore, a = -1 and we can plug this value into the polynomial to find the remainder:
P(-1) = k(-1)3 - 4(-1)2 + (-1) + 4
Simplifying this equation gives us:
P(-1) = -k - 4 - 1 + 4
P(-1) = -k - 1
Since we want the remainder to be -6, we can set P(-1) equal to -6 and solve for k:
-k - 1 = -6
-k = -5
k = 5

The x intercept and y intercept of the equation is 8 and 200 respectively.
What are x Intercepts and y Intercepts?x intercept is the point on the line where it touches the X axis.
y intercept is the point on the line where it touches the Y axis.
Given equation is,
y = 200 - 25x
where y is the total amount in Amanda's school lunch account after purchasing lunches for x weeks.
x intercept is the point on X axis. Any point on x axis has y coordinate 0.
So x intercept is the x coordinate when y coordinate is 0.
0 = 200 - 25x
25x = 200
x = 8
This means that the amount in the account will become 0, after purchasing lunch for 8 weeks.
y intercept is the y coordinate when x coordinate = 0.
y = 200 - (25 × 0)
y = 200

Answer:
(a) 8 : 3
(b) 1 7/8 cups
Step-by-step explanation:
Given a recipe that calls for 2 cups of flour and 3/4 cup of water, you want to know the ratio in simplest terms, and the amount of water for 5 cups of flour.
Simplified ratioThe ratio can be written and simplified as a fraction. Fractions are divided in the usual way.
2/(3/4) = 2 ÷ 3/4 = 2 × 4/3 = 8/3 = 8 : 3
5 cups flour
If we multiply each term in this ratio by 5/8, we can find the recipe that uses 5 cups of flour:
(5/8)·8 : (5/8)·3 = 5 : 15/8 = 5 : 1 7/8
Naomi uses 1 7/8 cups of water with 5 cups of flour.

[tex]5:\frac{15}{8}[/tex]
5 cups flour needs [tex]\frac{15}{8}[/tex] ([tex]=1\frac{7}{8}[/tex]) cups water
How to find a height of a trapezoid with phythagorean theorem
Height of a trapezoid with Pythagorean theorem is = √{Hypotenuse ^2 - Base ^2}
Trapezoid has two parallel sides and two non parallel sides. The length of the parallel sides are unequal but the length of the non parallel sides are equal.
Thus the trapezoid can be divided into three parts where one is rectangle ( which has length equal to the shortest length of the parallel sides) and two triangles which are equal ( having equal base, height and hypotenuse).
The Pythagoras theorem on the triangular part of the trapezoid can be stated as ,
Hypotenuse ^2 = Base ^2 + Height ^2
⇒ Height ^2 = Hypotenuse ^2 - Base ^2
⇒ Height = √{ Hypotenuse ^2 - Base ^2}
where, Height of the triangle is equal to that of the trapezoid it belongs to;
Hypotenuse of the triangle is the non parallel but equal side of the trapezoid;
Base of the triangle is = {(length of the longest side of parallel sides of trapezoid) - (length of the shortest side of parallel sides of trapezoid) }/2

7. Higher Order Thinking Point N has
coordinates (3, 4). On a quiz yesterday, Ari
incorrectly claimed that if you rotate N 180°
about the origin, the coordinates of N' are
(-4, 3). What are the correct coordinates
for N'? What was Ari's likely error?
The correct coordinates of N' is (-3, -4).
What is Rotation:Rotation of coordinates involves changing the orientation of a point or object in a plane about a fixed point called the center of rotation.
This process can be accomplished by applying a set of transformation rules to the original coordinates of the object.
When a point (x, y) rotated about the origin at 180° then the coordinates resultant point are (-x, -y).
Here we have
Point N has coordinates (3, 4)
Given that the point N is rotated about 180°
As we know when the point (x, y) rotated about the origin at 180° then the resultant point is (-x, -y)
Here (3, 4) is rotated about 180°
The resultant point N' is (-3, -4)
Therefore,
The correct coordinates of N' is (-3, -4).

If the values of A and B make the equation 35x – 29/x^2-3x+2 = A/x-1 +b/x-2 true for all values of x for which it is defined, find A+B. (A) 6 (B) 29 (C) 35 (D) 47 (E) None of these
If the values of A and B make the equation 35x – 29/x²-3x+2 = A/x-1 +b/x-2 true for all values of x for which it is defined, A+B is 35.
The given equation is 35x - 29/(x² - 3x + 2) = A/(x - 1) + B/(x - 2).
We can simplify the denominator of the second term on the left hand side by factoring it:
35x - 29/[(x - 1)(x - 2)] = A/(x - 1) + B/(x - 2)
Now, we can multiply both sides of the equation by (x - 1)(x - 2) to get rid of the fractions:
35x(x - 1)(x - 2) - 29 = A(x - 2) + B(x - 1)
Expanding the left hand side gives us:
35x³ - 70x² + 35x - 29 = A(x - 2) + B(x - 1)
Now, we can compare the coefficients of x on both sides of the equation to find the values of A and B. The coefficient of x on the left hand side is 35, and on the right hand side it is A + B. Therefore, A + B = 35.
Therefore, the values of A and B make the equation 35x – 29/x^2-3x+2 = A/x-1 +b/x-2 true for all values of x for which it is defined is 35.

Jeff and Ella use a payment plan to buy new furniture. Jeff writes the equation y = –108x + 2240 to represent
the amount owed, y, after x payments. The graph shows how much Ella owes after each payment.
Whose furniture costs more, Jeff's or Ella's? Explain
Therefore, after 10 payments, Jeff owes $1160.
Since $1160 is less than $2200, we can conclude that Jeff's furniture costs less than Ella's.
What roles do equations play?A mathematical equation, such as 6 x 4 = 12 x 2, can be used to compare two amounts or values. a significant noun. An equation is employed when it's required to integrate two or more elements in order to understand or fully explain a situation.
To determine whose furniture costs more, we need to compare the amounts owed by Jeff and Ella for the same number of payments.
Jeff's equation is y = -108x + 2240, which gives the amount owed after x payments.
Ella's graph does not have an equation provided, but we can see that after 10 payments, she owes approximately $2200.
To compare the amounts owed after 10 payments, we can substitute x = 10 into Jeff's equation:
y = -108(10) + 2240
y = -1080 + 2240
y = 1160
Therefore, after 10 payments, Jeff owes $1160.
Since $1160 is less than $2200, we can conclude that Jeff's furniture costs less than Ella's.
