The after-tax cost of the tennis racket is $101.70.

To calculate the after-tax cost of the tennis racket, we first need to find the sale price of the racket, then add on the HST.

Step 1: Find the sale price of the racket. To do this, we need to find 25% of $120, then subtract that amount from the original price.

25% of $120 = 0.25 × $120 = $30

Sale price = $120 - $30 = $90

Step 2: Add on the HST. To do this, we need to find 13% of the sale price, then add that amount to the sale price.

13% of $90 = 0.13 × $90 = $11.70

After-tax cost = $90 + $11.70 = $101.70

Therefore, the after-tax cost of the tennis racket is $101.70.

a. R = 1820 - 25t
b. R = 1820 - 25(7) = 1345 billion barrels
c. The world's oil reserves will be depleted when R = 0, so 25t = 1820, t = 72.8 years

a. The linear equation for the remaining oil reserves, R, in terms of t, the number of years since now, is R = 1820 - 25t. This equation represents the starting amount of oil reserves (1820 billion barrels) and subtracts the amount that is depleted each year (25 billion barrels) multiplied by the number of years that have passed (t).
b. Seven years from now, the oil reserves will be R = 1820 - 25(7) = 1820 - 175 = 1645 billion barrels.
c. To find when the world's oil reserves will be depleted, we need to solve for t when R = 0. So we have:

0 = 1820 - 25t
25t = 1820
t = 1820/25
t = 72.8
So, if the rate of depletion isn't changed, the world's oil reserves will be depleted in about 72.8 years.

A basis for a vector space is a set of linearly independent vectors that span the vector space. In this case, we need to find a basis for the vector space spanned by the given vectors (1,−1,2,2), (2,2,1,1), (2,−1,−1,0), and (4,2,−5,−3).

To find a basis, we can use the row reduction method. First, we write the given vectors as rows of a matrix:

```
1 -1  2  2
2  2  1  1
2 -1 -1  0
4  2 -5 -3
```

Next, we use row operations to reduce the matrix to row echelon form:

```

a.a=(p÷4)×(p÷4)

Answer: We know that the perimeter of a square is given by the formula:

P = 4s

where s is the side length of the square.

We can rearrange this equation to get:

s = P/4

The area of a square is given by the formula:

A = s^2

Substituting s = P/4, we get:

A = (P/4)^2

Simplifying this equation:

A = P^2/16

Therefore, the equation that can be used to find the area of a square that has a perimeter of P units is:

A = P^2/16

So, the correct answer is:

A. A = (P ÷ 4) x (P ÷ 4)

Answer:

  ∠A = 64°

Step-by-step explanation:

You have a triangle inscribed in a semicircle with acute angles marked A=(5x-1)° and C=(2x)°.

A triangle inscribed in a semicircle is a right triangle. (You know that because angle B is half the measure of 180° arc AC.) That means the two marked angles total 90°:

  (5x -1) +(2x) = 90

  7x = 91

  x = 13

Then angle A is ...

  A = (5·13 -1)° = (65 -1)° = 64°

The measure of angle A is 64°.

__

Check:

  C = (2x)° = (2·13)° = 26°

Then A+C = 64° +26° = 90°, as required.

Given that A = |b с| . |a d| and det(A) = -11, the following computations can be made:
(b) det(4A) det(A) = 4^2 * (-11) * (-11) = 1936
(c) det(2A - 1) = 2^2 * (-11) - 1 = -43
(d) det((24)^-1) = (1/24) ^2 = 1/576
(e) d a 9 det b h с e

The determinant of a matrix is defined as the sum of the products of the elements of the matrix multiplied by the corresponding cofactor. The cofactor is a signed minor of the matrix, which is obtained by deleting the row and column of the element for which the cofactor is being computed.
In the case of the matrix A = |b с| . |a d|, the determinant can be computed as follows:
|b с| . |a d| = (b*d) - (a*c)
Therefore, det(A) = (b*d) - (a*c) = -11.
To compute det(4A) det(A), first, find det(4A), which is equal to:
|4b 4c| . |4a 4d| = 4^2 * (b*d - a*c)
Thus, det(4A) = 16(b*d - a*c) = 16(-11) = -176.
Then, det(4A) det(A) = (-176) * (-11) = 1936.

For det(2A - 1), first, find 2A - 1, which is equal to:
|2b 2c| . |2a 2d| - |1 0| . |0 1|
= 2|b с| . |a d| - |1 0| . |0 1|
= 2A - |1 0| . |0 1|
= 2A - I
where I is the identity matrix.
Therefore, det(2A - 1) = det(2A - I) = det(2A) det(I^-1)
Since det(I) = 1, det(I^-1) = 1/det(I) = 1/1 = 1.
Therefore, det(2A - 1) = 2^2 * (-11) * 1 - 1 = -43.
Finally, to compute det((24)^-1), it is necessary to find the inverse of the matrix 24.
|a b| . |c d| = 24I
=> |a b|^-1 . |c d| = (1/24)I
=> (1/24) . |d -b| . |-c a| = (1/24)I
Therefore, |d -b| . |-c a| = I
Since the determinant of the identity matrix is 1, it follows that:
1 = det(I) = det(|d -b| . |-c a|) = (a*d) - (b*c)
Hence, det((24)^-1) = (1/24)^2 = 1/576.

5 28,000

10 30,000

15 31,000

25 33,000

30 34,000

(a) Pearson's correlation coefficient:

We can use the formula

r = (nΣxy - ΣxΣy) / sqrt[(nΣx² - (Σx)²)(nΣy² - (Σy)²)]

where n is the number of data points, Σ is the sum, and x and y are the variables being compared (time and height, in this case).

Using the given data, we get:

n = 6

Σx = 85

Σy = 181000

Σx² = 1375

Σy² = 503,710,000

Σxy = 2,886,000

Substituting into the formula, we get:

r = (62,886,000 - 85181000) / sqrt[(61375 - 85²)(6503710000 - 181000²)]

r = 0.994

Therefore, Pearson's correlation coefficient is 0.994, indicating a strong positive correlation between time and height.

(b) Rocket's acceleration:

We can use the formula:

h = ut + (1/2)at²

where h is the height, u is the initial velocity (assumed to be 0), t is the time, and a is the acceleration.

Rearranging, we get:

a = 2h/t²

Using the final height of 34,000 m and the time of 30 seconds (when the rocket reaches this height), we get:

a = 2*34000/(30²)

a = 75.6 m/s²

Therefore, the rocket's acceleration is 75.6 m/s².

He should use 11.11 pounds of the $0.90 per pound coffee, and 16.89 pounds of the $2.40 per pound coffee for a total cost of 28 pounds.

x + y = 28

0.90x + 2.40y = 38.20

x = 11.11, y = 16.89

The grocer wants to mix 28 pounds of two kinds of coffee, one selling for $0.90 per pound and the other for $2.40 per pound, and sell it for $1.45 per pound. To determine how many pounds of each kind to use in the new mix, we can set up a system of equations. Let x represent the quantity of pounds of coffee priced at $0.90 per pound and y the quantity of pounds of coffee priced at $2.40 per pound. Thus, x + y = 28 (the total number of pounds) and 0.90x + 2.40y = 38.20 (the total cost of the 28 pounds, at $1.45 per pound). Solving this system of equations yields x = 11.11 pounds of the $0.90 per pound coffee and y = 16.89 pounds of the $2.40 per pound coffee. Therefore, the grocer should use 11.11 pounds of the $0.90 per pound coffee, and 16.89 pounds of the $2.40 per pound coffee for a total of 28 pounds.

The  two possible solutions to A XYZ, Y = 60.5°, x = 15.2 cm, y = 14 cm are:

X ≈ 85.86°, Y = 60.5°, Z ≈ 59.64°, x = 15.2 cm, y = 14 cm, z ≈ 9.05 cm

X ≈ 94.14°, Y = 60.5°, Z ≈ 59.64°, x = 15.2 cm, y = 14 cm, z ≈ 29.53 cm

To solve triangle XYZ,

We can use the Law of Sines and Law of Cosines:

First, we can use the Law of Sines to find angle Z:

sin(Z)/14 = sin(60.5)/15.2

sin(Z) = (14/15.2)*sin(60.5)

Z ≈ 59.64°

Now we can use the Law of Cosines to find the length of side z:

z² = 14² + 15.2² - 2(14)(15.2)cos(59.64)

z ≈ 9.05 cm or z ≈ 29.53 cm

For the first solution, z = 9.05 cm:

Now we can use the Law of Sines again to find angle X:

sin(X)/15.2 = sin(59.64)/9.05

sin(X) = (15.2/9.05)*sin(59.64)

X ≈ 85.86°

For the second solution, we use the supplementary angle to angle X:

X = 180 - 85.86 = 94.14°

Now we can use the Law of Sines again to find the length of the second solution for side z:

sin(Z)/14 = sin(60.5)/15.2

sin(Z) = (14/15.2)*sin(60.5)

Z ≈ 59.64°

z² = 14² + 15.2² - 2(14)(15.2)cos(59.64)

z ≈ 29.53 cm

Therefore, the two possible solutions for triangle XYZ are:

X ≈ 85.86°, Y = 60.5°, Z ≈ 59.64°, x = 15.2 cm, y = 14 cm, z ≈ 9.05 cm
