When substituting y = 11 into the equation y = 1/2(x) - 25, we find that x = 72, confirming that (23.5, 11) is a valid point of intersection.

Given that x is 23.5, it is required to prove that it is an intersection point for the equation y = 1/2(x) - 25 when y is equal to 11.

The equation is given as y = 1/2(x) - 25

When y = 11, we can substitute the value of y in the equation to obtain 11 = 1/2(x) - 25

This can be simplified as 11 + 25 = 1/2(x)36 = 1/2(x)

On solving, x = 72Thus, when y is equal to 11 and x is equal to 72, the given point of intersection is valid.

Therefore, it can be concluded that x = 23.5 is a point of intersection for the equation y = 1/2(x) - 25 when y is equal to 11.

In summary, when given an equation with two variables, we can find the point of intersection by setting one of the variables to a given value and solving for the other variable. In this case, when y is equal to 11, we can solve for x and obtain the point of intersection as (72,11).

Step-by-step explanation:

Answer:

1) Shirt = $28.20  Jeans = $42

2) subtotal = $105.20

3) with the discount from the coupon, the pre-tax cost is $83.90

4) about $ 88.10 (actual answer was $88.095)

5) i have no clue bro, im sorry

Step-by-step explanation:

The sale price of the shirt  is \(\$28.20\) The sale price of the jeans  \(\$42.00\) Subtotal is \(\$\)105.20 Pre-tax cost  \(\$78.90\) The total amount charged with 5% sales tax is  \(\$42.00\)

The sale price of the shirt:

Given -The original price of the shirt is $47, and it is on a "40% Off" sale. To find the sale price, we can calculate \(40\% of \$47\)and subtract it from the original price:

The sale price of the shirt = \(\$47 - (40\% \times\$47)\)

The sale price of the shirt =\(\$47 - (\$18.80)\)

The sale price of the shirt =\(\$28.20\)

The sale price of the jeans:

Given =The original price of the jeans is $60, and it is advertised as "30% Off." Similar to the shirt, we can calculate the sale price of the jeans:

The sale price of the jeans =\(\$60 - (30\% \times\$60)\)

The sale price of the jeans =\(\$60 - (\$18.00)\)

The sale price of the jeans = \(\$42.00\)

Subtotal of the shirt, jeans, and shoes:

Subtotal = Sale price of the shirt + Sale price of the jeans + Sale price of the shoes

Subtotal = \(\$\)28.20 + \(\$\)42.00 +\(\$\)35.00

Subtotal =\(\$\)105.20

The pre-tax cost of your purchase with the\(25\%\) off coupon:

The 25% off coupon is applied to the subtotal. We calculate 25% of the subtotal and subtract it from the subtotal to find the pre-tax cost:

Pre-tax cost = Subtotal -\((25\% \times Subtotal)\)

Pre-tax cost = \(\$105.20 - (25\% \times \$105.20)\\\)

Pre-tax cost =\(\$105.20 - (\$26.30)\)

Pre-tax cost = \(\$78.90\)

The total amount charged with 5% sales tax:

To calculate the total amount charged, we need to add the sales tax to the pre-tax cost:

Sales tax = \(5\% \times Pre-tax cost\)

The Total amount charged = Pre-tax cost + Sales tax

The Total amount charged =\(\$78.90 + (5\% \times \$78.90)\)

The total amount charged = \(\$78.90 + \$3.94\)

The total amount charged =\(\$82.84\)

From the given charges , required equation to find the number of hours afford by Jenny is 250 = 50 + 25h and the number of hours Jenny can afford is 8 hours.

As given in the question,

Let 'h' be the number of hours Jenny can afford.

Jenny's budget amount = $250

Service charges of consultation fees = $50

Per hour labor charges = $25

For the 'h' hours of service and with the budget of $250 ,

Required equation is :

250 = 50 + 25h

Simplify the equation to get number of hours

Subtract 50 from both the sides

250 -50 = 50 -50 +25h

⇒ 200 = 25h

⇒ h = 200/25

⇒ h =8 hours

Therefore, from the given charges , required equation to find the number of hours afford by Jenny is 250 = 50 + 25h and the number of hours Jenny can afford is 8 hours.

The total area from the graph is 2.737.

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

First of all, lets calculate the points of intersection (P, Q, R)

x²+3=(x+2) +5

x²-2=√(x+2)

x⁴+4-4x²=x+2

x⁴-4x²-x+2=0

(x-2)(x³+2x²-1)=0

(x-2)(x+1)(x²+x-1)=0

x=2, -1, -1±√(1+4)/2

Clearly, the x-coordinate of Q is -1, P is -1-√5/2, R is -1+√5/2, S is 2

So the limit of integration will be

P( (-1-√5)/2, (-1-√5/2)² +3)=P((-1-√5)/2, (3+√5/2))

Q(-1, (-1)²+3)=Q(-1, 4)

Area A:

\(\int\limits^\frac{3+\sqrt{5} }{2} _4 {-\sqrt{-y-3}-((y-5)^2 -2)} \, dx\)

= \([\frac{-(y-3)^\frac{3}{2} }{\frac{3}{2} }-\frac{(y-5)^3}{3}+3y]^{\frac{3+\sqrt{5} }{2} }_4\)

= 2.07

Area B:

\(\int\limits^\frac{-1+\sqrt{5} }{2} _4 {-\sqrt{x+2}+5-(x^2+3)} \, dx\)

= \([\frac{-(x+2)^\frac{3}{2} }{\frac{3}{2} }+5x-\frac{x^3}{3}-3x]^{\frac{-1+\sqrt{5} }{2} }_{-1}\)

= 0.667

Total area = 2.07+0.667

= 2.737

The amount the women would pay for 2.4 kg of chicken and 2 kg of meat in total is $15.2

The meaning of unit price is a price quoted in terms of so much per agreed or standard unit of product or service

Given that, a woman bought 1.8 kg of chicken and 1.6 kg of meat. The chicken cost $5.40 and the meat cost $6.40,

We need to find, if she had bought 2.4 kg of chicken and 2 kg of meat, how much would she have had to pay,

To find the same, we will first find the unit price of each,

Unit price = total price / total quantity

Since, 1.8 kg of chicken costs $5.40,

Therefore, 1 kg will cost = 5.40 / 1.8 = $3

Similarly,

If 1.6 kg of meat costs $6.40,

Therefore, 1 kg will cost = 6.40 / 1.6 = $4

Now, to find the cost of 2.4 kg of chicken and 2 kg of meat, we will multiply the unit prices to the required quantities,

Therefore,

2.4 kg of chicken will cost = 2.4 x 3 = $7.2

2 kg of meat will cost = 2 x 4 = $8

In total, she had to pay = 8+7.2 = $15.2

Hence, the amount the women would pay for 2.4 kg of chicken and 2 kg of meat in total is $15.2

Answer: 512 ft^2, 720 ft^2

Step-by-step explanation:

Answer:

Step-by-step explanation:

(a) The area formula for a rectangle is Length x Width.

For this case, the Area = (32 ft)x(16 ft) = 512 ft^2

(b) To find the area of just the deck, we need to find the area of the larger rectangle as a whole, then subtract out the area of the smaller rectangle inside. This will give us the area of just the shaded deck portion.

Area (of the bigger rectangle) = LengthxWidth = (28)x(44) = 1,232 ft^2

The correct graph of the inequality ( |x| + 3 > 3) is attached accordingly.

Recall that the absolute value (or modulus) of a real number x is its non-negative value regardless of its sign. For example, 5 has an absolute value of 5, and 5 has an absolute value of 5.

A number's absolute value can be conceived of as its distance from zero along the real number line.

So, given  |x| + 3 > 3

Add minus three to both sides

|x| + 3  + (-3) > 3 + (-3)

|x|  > 0

The possible exact values of the trigonometric functions of θ are:

sin θ = -1/√3,  cos θ = √3/3, sec θ = √3

The law of sines, also known as the sine rule, is a mathematical principle that relates the sides and angles of a triangle. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is constant for all three sides of the triangle.

Trigonometric functions are mathematical functions that relate angles to the ratios of the sides of a right triangle. The six primary trigonometric functions are sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot). Each function represents a different ratio of two sides of a right triangle and can be used to solve problems in geometry, physics, engineering, and other fields that involve angles and triangles.

According to the given information,

Given that tan θ = -√(1/3) and 0 < θ < 180°, we can use the trigonometric identities to find the values of the other trigonometric functions of θ.

First, we can use the definition of the tangent function:

tan θ = opposite/adjacent

Since tan θ = -√(1/3), we can assign opposite = -1 and adjacent = √3 as their ratio equals -√(1/3). This means that the terminal side of the angle θ will lie in the fourth quadrant of the unit circle since the opposite is negative and the adjacent is positive.

Next, we can use the Pythagorean identity:

sin²θ + cos²θ = 1

to find the value of sin θ. Since we know that θ is in the fourth quadrant, we can assign sin θ = -1/√3, since sin θ is negative in the fourth quadrant and the ratio of opposite/hypotenuse of a 30-60-90 triangle is √3/2, which means the ratio of hypotenuse/opposite is 2/√3 = √3/3.

Then, we can use the definition of the cosine function:

cos θ = adjacent/hypotenuse

to find the value of cos θ. We know that adjacent = √3 and the hypotenuse is positive (since it is a length), so we can assign cos θ = √3/3.

Finally, we can use the reciprocal identity:

sec θ = 1/cos θ

to find the value of sec θ. We know that cos θ = √3/3, so we can assign sec θ = √3.

Therefore, the possible exact values of the trigonometric functions of θ are:

sin θ = -1/√3

cos θ = √3/3

tan θ = -√(1/3)

sec θ = √3

Direct distance between the ship and the harbour would be, 5ln3 km.

What is Pythagorean Theorem?

The Pythagorean Theorem is an important mathematical theorem used to calculate the length of the sides of a right triangle. It states that the square of the hypotenuse (the longest side) of a right triangle is equal to the sum of the squares of the other two sides. In equation form, it can be expressed as a2 + b2 = c2, where a and b are the lengths of the two shorter sides, and c is the length of the hypotenuse. Although the theorem was proven by the ancient Greek mathematician Pythagoras, it is still widely used today in mathematics and engineering. It is used to calculate the length of any side of a right triangle as long as the lengths of the other two sides are known. It also has numerous applications in engineering and physics, including the calculation of forces in bridges, navigation problems, and the design of airplanes. It is also used in trigonometry to calculate angles and is a key tool in calculus.

According to Pythagorean Theorem,

\((AC)^{2} = (AB)^{2} +(BC)^{2}\\\\(AC)^{2} = (4ln3)^{2} + (3ln3)^{2} \\\\(AC) \ = \sqrt{(25ln3)^{2}} \\\\(AC) \ = 5ln3\)

Since both of the factors are binomials, FOIL Method may be used.

Product of the First terms: (x)(2x)= 2x²

Product of the Outer terms: (x)(3)= 3x

Product of the Inner terms: (-2)(2x)= -4x

Product of the Last terms: (-2)(3)= -6

Since the product of the outer and the inner terms are like terms, we may add the two products.

Thus, combining all terms in one expression would be as follows.

Linear Modeling

The equation y = -4x can be used to model the change in depth of the descent of the DeepSea Challenger, where y is the depth in feet and x is the time in seconds.

For example, for x=10 seconds, the vessel had traveled y= -4*10 = -40 feet.

The bottom of Challenger Deep in the Marianas Trench is 35,814 feet deep at its lowest point.

If we use the model, we can find the value of x when y= -35,814 feet

-35,814 =-4x

Dividing by 4:

x = -35,814/ (-4)

x = 8,953.5 seconds

The model suggests the DeepSea Challenger took almost 9,000 seconds to reach the bottom
