If Cole brought 21 cans and his sister brought 7 cans less, then the total number of cans brought by them is 35 cans.
The number of cans which Cole brought = 21 cans of food.
His sister brought in 7 fewer cans than he did, which means she brought in:
⇒ 21 - 7 = 14 cans of food,
Let the total number of food-cans be = "f",
So, the equation to find the number of cans is written as :
⇒ x = 21 + 14,
On adding the number of cans,
We get,
⇒x = 21 + 14 = 35,
Therefore, together they brought in 35 cans of food.

Sally owns a restaurant in Wooville. The city is trying to get a minor league team to move there in 2021, either to location A (near her restaurant) or location B. The team might stay in location C in another city. The probability of these events, and her estimated annual profit in 2021 are shown in the table below.
The standard deviation of the restaurant profits in 2021 is given by $71181.
Restaurant profit for outcome 'move to A' = $ 260000
Restaurant profit for outcome 'move to B' = $ 120000
Restaurant profit for outcome 'stay in C' = $ 100000
The mean of restaurant profits = $(260000 + 120000 + 100000)/3 =$ 160000.
Standard deviation of the restaurant profits in 2021 is given by
= $ √({(260000 - 160000)² + (120000 - 160000)² + (100000 - 160000)²}/3)
= $ √(((100000)² + (40000)² + (60000)²)/3)
= $ √(15200000000/3)
= $ √5066666667
= $ 71181 (rounded to the nearest dollar)
Hence standard deviation of the restaurant profits in 2021 is given by $71181.

Figure 1 and Figure 2 below are congruent. Which point corresponds to point C'?
The point in Figure 2 that corresponds to point L in Figure 1 is the midpoint of line segment NP.
When two figures are congruent, it means that they have the same shape and size. This implies that corresponding points in the two figures have the same position and distance from each other.
In Figure 1, the points I, J, L, K, N, P, and Q are labeled. To find the point in Figure 2 that corresponds to point L, we need to look for a point that has the same relative position and distance as point L in Figure 1.
From Figure 1, we can see that point L is the midpoint of the line segment JK. Therefore, to find the corresponding point in Figure 2, we need to look for a point that is the midpoint of the line segment that corresponds to JK. In Figure 2, the line segment that corresponds to JK is NP, and the midpoint of NP corresponds to the point that is equivalent to point L. Therefore, the point that corresponds to point L in Figure 2 is the midpoint of line segment NP.
It is important to note that identifying corresponding points in congruent figures is a fundamental concept in geometry and is often used to solve problems involving congruence and similarity.

please do it with explanation.
The value of the angles in the parallelogram are:
∠ABC = 70°
∠DCP =70°
How to calculate the angles in the parallelogram?Recall that two adjacent angles in a parallelogram add up to 180 degrees. We can say:
∠BAD + ∠ABC = 180° (Where ∠BAD = 110°)
∠ABC = 180 - 110 = 70°
Since PC = BC, ∠BPC = 70°
Also, ∠BCP = 180 - 70 - 70 = 40° (Sum of angles in a triangle)
∠ACB = ∠BAD (opposite angles of parallelogram are equal)
Where ∠BAD = 110°
Thus, ∠ACB = 110°
∠ACB = ∠DCP + ∠BCP

A student is graduating from college in 12 months but will need a loan in the amount of $11,650 for the last two semesters. The student may receive either an unsubsidized Stafford Loan
or a PLUS Loan. The terms of each loan are:
Unsubsidized Stafford Loan: annual interest rate of 5.95%, compounded monthly, and a payment grace period of six months from time of graduation
PLUS loan: annual interest rate of 6.55%, compounded monthly, with a balance of $12,436.41 at graduation
Which loan will have a lower balance, and by how much, at the time of repayment?
O The PLUS loan will have a lower balance by $298.35 at the time of repayment.
O The Stafford loan will have a lower balance by $298.35 at the time of repayment.
O The PLUS loan will have a lower balance by $527.14 at the time of repayment.
O The Stafford loan will have a lower balance by $527.14 at the time of repayment
Based on the information, the Stafford loan will have a lower balance by $527.14 at the time of repayment
How to calculate the loanUsing the formula for compound interest, the total cost of the loan can be calculated as follows:
Total cost of Stafford loan = $11,650 x (1 + 0.0595/12)^(12*0.5) = $12,652.14
Total cost of PLUS loan = $12,436.41 x (1 + 0.0655/12)^12 = $13,179.28
Therefore, the Stafford loan will have a lower balance at the time of repayment by $527.14 ($13,179.28 - $12,652.14).

For f(x) = x2 -4 and g(x) = 2x + 3, what is the domain of f - g?
A) (-90, ∞0)
B) (-2, 2)
C) (2, ∞)
D) [0, %)
Answer:
To determine the domain of f - g, we need to first find the expression for f - g.
f - g = (x^2 - 4) - (2x + 3)
f - g = x^2 - 2x - 7
The domain of f - g is the set of all real numbers for which the expression x^2 - 2x - 7 is defined.
We know that a quadratic expression of the form ax^2 + bx + c is defined for all real numbers x, so long as the expression under the square root in the quadratic formula (b^2 - 4ac) is non-negative.
In this case, a = 1, b = -2, and c = -7, so the expression under the square root is:
b^2 - 4ac = (-2)^2 - 4(1)(-7) = 4 + 28 = 32
Since 32 is positive, we know that the expression x^2 - 2x - 7 is defined for all real numbers x, and therefore the domain of f - g is all real numbers.

Ivy Tech Tuition was $88.34 per credit hour in 2006. Use the CPI values to determine what the school would be charging in 2013 if they only increased tuition based on inflation.
Answer: they would be charging $102.66 per credit hour in 2013.
Step-by-step explanation:
To determine what Ivy Tech would be charging in 2013 if they only increased tuition based on inflation, we need to use the CPI values to adjust for inflation between 2006 and 2013.
First, we need to calculate the inflation rate between the two years:
Inflation rate = CPI in 2013 / CPI in 2006
Inflation rate = 234.531 / 201.6 = 1.162
This means that the cost of living increased by 16.2% between 2006 and 2013.
Next, we can use this inflation rate to calculate the adjusted tuition cost for 2013:
Tuition in 2013 = Tuition in 2006 x (CPI in 2013 / CPI in 2006)
Tuition in 2013 = $88.34 x (234.531 / 201.6)
Tuition in 2013 = $102.66 (rounded to the nearest cent)
Therefore, if Ivy Tech only increased tuition based on inflation, they would be charging $102.66 per credit hour in 2013.

Face 1: The front and back faces both have dimensions of 12 ft by 14 ft, so the area of each is:
12 ft × 14 ft = 168 ft²
Two of these faces, so the total area is:
2 × 168 ft² = 336 ft²
Face 2: The top and bottom faces both have dimensions of 20 ft by 14 ft, so the area of each is:
20 ft × 14 ft = 280 ft²
Two of these faces, so the total area is:
2 × 280 ft² = 560 ft²
Face 3: The left and right faces both have dimensions of 12 ft by 20 ft, so the area of each is:
12 ft × 20 ft = 240 ft²
Two of these faces, so the total area is:
2 × 240 ft² = 480 ft²
Now add up the areas of all the faces:
336 ft² + 560 ft² + 480 ft² = 1,376 ft²
11. To find the surface area of the figure, add the areas of all six faces.
Find the area of the rectangular faces:
The front and back faces both have dimensions of 14 in by 14 in, so each has an area of 14 in x 14 in = 196 in².
The top and bottom faces both have dimensions of 13 in by 8.9 in, so each has an area of 13 in x 8.9 in = 115.7 in².
Find the area of the triangular faces. Use the Pythagorean theorem to find the length of the third side of each triangle:
The two side faces are congruent triangles with legs of 14 in and 13 in.
Using the Pythagorean theorem, find the length of the hypotenuse to be √(14² + 13²) ≈ 19.14 in. The area of each triangle is then 1/2 base x height = 1/2 x 19.14 in x 8.9 in ≈ 85.3 in².
Using the Pythagorean theorem, find the length of the hypotenuse to be √(8.9² + 13²) ≈ 15.8 in. The area of each triangle is then 1/2 base x height = 1/2 x 15.8 in x 14 in ≈ 110.6 in².
Finally, add up the areas of all six faces:
Front and back faces: 2 x 196 in² = 392 in²
Top and bottom faces: 2 x 115.7 in² = 231.4 in²
Side faces: 2 x 85.3 in² = 170.6 in²
End faces: 2 x 110.6 in² = 221.2 in²
The total surface area is the sum of these areas:
392 in² + 231.4 in² + 170.6 in² + 221.2 in² ≈ 1,015.2 in²

Find the length of the segment.
Answer:
CD = 4 , AD = 6
Step-by-step explanation:
AC is an angle bisector of ∠ BAD and divides the opposite side from the angle into segments that are proportional to the other two sides, that is
[tex]\frac{BC}{CD}[/tex] = [tex]\frac{AB}{AD}[/tex] ( substitute values )
[tex]\frac{6}{y-1}[/tex] = [tex]\frac{9}{2y-4}[/tex] ( cross- multiply )
6(2y - 4) = 9(y - 1) ← distribute parenthesis
12y - 24 = 9y - 9 ( subtract 9y from both sides )
3y - 24 = - 9 ( add 24 to both sides )
3y = 15 ( divide both sides by 3 )
y = 5
Then
CD = y - 1 = 5 - 1 = 4
AD = 2y - 4 = 2(5) - 4 = 10 - 4 = 6
Given the dimensions of a rectangle are (x-1)&(x+7) meters, find the value of x if the area of the rectangle is 128 square feet
Answer:
x = 12
Step-by-step explanation:
We are given that the dimensions of a rectangle are (x-1) and (x+7) meters, and we know that the area of the rectangle is 128 square meters.
We can set up an equation to solve for x as follows:
Area of rectangle = Length × Width
128 = (x-1)(x+7)
Expanding the right side, we get:
128 = x^2 + 6x - 7
Bringing all the terms to one side, we get:
x^2 + 6x - 135 = 0
Now we can use the quadratic formula to solve for x:
x = (-6 ± √(6^2 - 4(1)(-135))) / (2(1))
x = (-6 ± √936) / 2
x = (-6 ± 30) / 2
x = -3 ± 15
x = -18 or x = 12
Since x represents a length, it must be positive. Therefore, the value of x is 12.

However, in the polar coordinate system, angles are typically expressed in radians between 0 and 2π. The angle π/6 is equivalent to 0.5236 radians, so the correct polar coordinates of the point (2√3, 2) are (r, θ) = (4, π/6).

The Taylor series for f(x) = e^2x at x = 1 is option D. Σ2ⁿ e²ˣ/n! (x - 1)ⁿ
How did we get the value?The Taylor series for a function f(x) centered at x = a is given by:
f(x) = f(a) + f'(a)(x-a)/1! + f''(a)(x-a)^2/2! + f'''(a)(x-a)^3/3! + ...
f'(a), f''(a), f'''(a), ... depict the first, second, third, and higher derivatives of f(x) evaluated at x = a.
In this case:
f(x) = e^(2x)
The first derivative is:
f'(x) = 2e^(2x)
The second derivative is:
f''(x) = 4e^(2x)
The third derivative is:
f'''(x) = 8e^(2x) etc.
Finding the Taylor series for f(x) = e^(2x) at x = 1, evaluate each derivative at x = 1:
f(1) = e^(2)
f'(1) = 2e^(2)
f''(1) = 4e^(2)
f'''(1) = 8e^(2) etc.
Plug these values into the Taylor series formula:
f(x) = f(1) + f'(1)(x-1)/1! + f''(1)(x-1)^2/2! + f'''(1)(x-1)^3/3! + ...
f(x) = e^(2) + 2e^(2)(x-1)/1! + 4e^(2)(x-1)^2/2! + 8e^(2)(x-1)^3/3! + ...
Simplify:
f(x) = e^(2) + 2e^(2)(x-1) + 2e^(2)(x-1)^2 + 4e^(2)(x-1)^3/3 + ...
Therefore, the Taylor series for f(x) = e^(2x) at x = 1 is: Σ2ⁿ e²ˣ/n! (x - 1)ⁿ which is option D.

hi can someone help with this question
Based on the information, we can infer that the investment was made 11.53 years ago.
How to calculate how many years ago was the investment made?To calculate how many years ago was the investment mafe we have to can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = the final amount
P = the principal (initial amount invested)
r = the interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the number of years
Let's start by finding the initial principal (P) by working backwards from the final amount (A):
A = P(1 + r/n)^(nt)
31372.0 = P(1 + 0.022/1)^(14)(1 + 0.022+0.007/1)^(1(t-4))
Simplifying, we get:
31372.0 = P(1.093248)(1.029)^(t-4)
P = 27500 euros (initial investment)
Now we can solve for t:
31372.0 = 27500(1.093248)(1.029)^(t-4)
1.1412 = (1.029)^(t-4)
log(1.1412) = log(1.029)^(t-4)
t - 4 = log(1.1412)/log(1.029)
t = log(1.1412)/log(1.029) + 4
t = 11.53
Therefore, the investment was made about 11.53 years ago.
