Challenge of the day

Answer: $15.37

Yes, proportional

Step-by-step explanation:

Ok So the Equation Here is

y = 1.73x + 4.99

The reason why 4.99 doesn't have a variable is because of the fact it's not being manipulated by time like the 1.73 is. It's a flat rate of 4.99 for the card itself, no increase or decrease in years. However, the 1.73 is affected by how ever many years the player is in retirement. That's why it has X because the amount of 1.73 needs to be multiplied by however many years hes been in retirement.

So Substitute 6 (because 2006 is what year we need to find) for x and we get

y = 1.73(6) + 4.99

Which if you simplify in a calculator or do it in your paper, comes out to be $15.37

The total number of different pizzas that Sarah can order is 42. The correct option is C.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Given the following choices for selecting a pizza. Therefore, we can write,

Number of choices for size = 2

Number of choices for toppings = 7

Number of choices for crust = 3

Total number of choices available with Sarah = Number of choices for size × Number of choices for toppings × Number of choices for crust

Total number of choices available with Sarah = 2 × 7 × 3 = 42

Hence, the total number of different pizzas that Sarah can order is 42.

Question:

A 33 foot ladder leans against a building so that the angle between the ground and the ladder is 75º. How high does the ladder reach up the side of the building?

Round to 2 decimal places feet.

Answer:

[tex]H = 31.88[/tex]

Step-by-step explanation:

The question is illustrated using the attachment as a sketch.

We have that

[tex]Ladder = 33ft[/tex]

[tex]\theta = 75[/tex]

Required

Determine how high the ladder is to the building

Represent the length of the ladder with L and how high the ladder is on the building with H.

The relationship between L, H and [tex]\theta[/tex] is"

[tex]Sin\theta = \frac{H}{L}[/tex]

Substitute values for L and [tex]\theta\\[/tex]

[tex]Sin(75) = \frac{H}{33}[/tex]

Make H the subject

[tex]H = 33 * Sin(75)[/tex]

[tex]H = 33 * 0.9660[/tex]

[tex]H = 31.88[/tex]

Hence, the height to which the ladder reaches is approximately 31.88ft

Step-by-step explanation:

Given:

The quadratic equation is

[tex]0=-3x^2-4x+5[/tex]

To find:

The simplest radical form of the solution.

Solution:

Quadratic formula:

If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have,

[tex]0=-3x^2-4x+5[/tex]

Here, a=-3, b=-4 and c=5. Putting these values in the quadratic formula, we get

[tex]x=\dfrac{-(-4)\pm \sqrt{(-4)^2-4(-3)(5)}}{2(-3)}[/tex]

[tex]x=\dfrac{4\pm \sqrt{16+60}}{-6}[/tex]

[tex]x=\dfrac{4\pm \sqrt{76}}{-6}[/tex]

[tex]x=\dfrac{4\pm 2\sqrt{19}}{-6}[/tex]

Taking 2 common, we get

[tex]x=\dfrac{2(2\pm \sqrt{19})}{-6}[/tex]

[tex]x=\dfrac{(2\pm \sqrt{19})}{-3}[/tex]

[tex]x=-\dfrac{(2\pm \sqrt{19})}{3}[/tex]

Therefore, the correct option is A.

Answer:

Option b) 3x - 22 = 38 should be the correct answer.

Step-by-step explanation:

If we solve the equation, we get:

x = 20

So each bag had 20 apples. In total, 3 bags held 60 apples. If he gives away 22 apples to his friends, he has 38 remaining and this satisfies the discription given in the question.

Therefore, option B) 3x -22 = 38 should be your answer.

(tan²(θ) cos²(θ) - 1) / (1 + cos(2θ))

Recall that

tan(θ) = sin(θ) / cos(θ)

so cos²(θ) cancels with the cos²(θ) in the tan²(θ) term:

(sin²(θ) - 1) / (1 + cos(2θ))

Recall the double angle identity for cosine,

cos(2θ) = 2 cos²(θ) - 1

so the 1 in the denominator also vanishes:

(sin²(θ) - 1) / (2 cos²(θ))

Recall the Pythagorean identity,

cos²(θ) + sin²(θ) = 1

which means

sin²(θ) - 1 = -cos²(θ):

-cos²(θ) / (2 cos²(θ))

Cancel the cos²(θ) terms to end up with

(tan²(θ) cos²(θ) - 1) / (1 + cos(2θ)) = -1/2

Answer:

This is why [tex]\frac{1}{14}[/tex] x 42 = 3

Step-by-step explanation:

[tex]\frac{1}{14}[/tex] x 42 can also be written as [tex]\frac{1}{14}[/tex] x [tex]\frac{42}{1}[/tex]

we can reduce diagonally by 7 so [tex]\frac{1}{14}[/tex] x [tex]\frac{42}{1}[/tex] = [tex]\frac{1}{2}[/tex] x [tex]\frac{6}{1}[/tex]

now we multiply across [tex]\frac{1}{2}[/tex] x [tex]\frac{6}{1}[/tex] = [tex]\frac{6}{2}[/tex]

6 divided by two or [tex]\frac{6}{2}[/tex] = [tex]\frac{3}{1}[/tex] or 3

a.) The equation for profit is  - 0.5x² + 40x - 300

b.) The two values of x for profit = $300 are 20 and 60

c.) Profit of $15000 is not possible.

What is a profit?

Profit is defined as the total extent of benefit gained from selling some things. Mathematically, it is illustrated as the difference between the selling price and the cost price of an object.

Calculating the expression for profit

Given: the cost of producing x items = 55x + 300 and the revenue for selling x items is 95x - 0.5x²

a.) Profit = selling price/revenue - cost price

According to the question, we get,

Profit = 95x - 0.5x² - 55x - 300

= 40x - 0.5x² - 300

= - 0.5x² + 40x - 300                  —–— 1

b.) Finding two values of x, when profit is $300

Using equation 1, we get,

300 = - 0.5x² + 40x - 300

0.5x² - 40x + 600 = 0

0.5x² - 10x - 30x + 600 = 0

0.5x(x - 20) - 30(x - 20) = 0

(x - 20)(0.5x - 30) = 0

i.e. x = 20 or x = 60

Two values of x for profit = $300

c.) Let us consider the profit to be $15000

15000 = - 0.5x² + 40x - 300

0.5x² - 40x + 15300 = 0

Using the quadratic formula, x = (- b ± √b² - 4ac) / 2a, we get,

x = (40 ± √40² - 4(0.5)(15300)) / 2(0.5)

The roots of this equation will be imaginary. Thus, it can be said that profit can not be $15000.

Hence, a.) The equation for profit is  - 0.5x² + 40x - 300

b.) The two values of x for profit = $300 are 20 and 60

c.) Profit of $15000 is not possible.
