Answer:

C

Step-by-step explanation:

All you do is take the number choices and plug it into the equation. For example if you take A and plug it in the equation would look like -5(-5) < 25 and -5 times -5 is 25 so you know 25 is equal to 25 not less than.

If you plug in C you get -5(-4) < 25 and -5 times -4 is 20 and 20 is indeed less than 25

Answer:

x + y [tex]\leq 6[/tex]

Step-by-step explanation:

The amount of Oranges (x) and the amount of Mangoes (y) will add up to be less than or equal to 6.  

This condition is represented by the inequality x + y ≤ 6

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

In this case, Trish wants to buy x oranges and y mangoes, and she intends to carry them in her bag.

Her bag can hold a maximum of 6 fruits.

Since she wants to buy both types of fruit, the total number of fruits must be less than or equal to 6.

The inequality to represent this situation is:

x + y ≤ 6

This inequality represents that the sum of the number of oranges and mangoes Trish buys should be less than or equal to 6, which is the maximum number of fruits her bag can hold.

Step-by-step explanation:

The amount of sales tax is $87.79.

Given a total purchase price of a sofa as $1,254.07 and state taxes of 7%.

We are required to calculate the amount of sales tax.

The amount of sales tax can be calculated by multiplying the purchase price by the sales tax rate.

Let's represent the sales tax rate by `r`.

Therefore, the sales tax formula is expressed as:

Sales tax = r * purchase price

In this case, the rate of the sales tax `r` is 7%.

Therefore, we have:r = 7% = 0.07

Now we substitute the values given into the formula:

Sales tax = 0.07 * $1,254.07= $87.79

Therefore, the amount of sales tax is $87.79.

The center of the sphere can be found by taking the average of the coordinates of points A and B, and the radius of the sphere is half the distance between points A and B.

Let's denote point A as (2, 1, 5) and point B as (6, 2, 22). We want to find the set of points P such that the distance from P to A is twice the distance from P to B.

We can express this condition mathematically as:

|PA| = 2|PB|

Using the distance formula, we can rewrite this equation as:

[tex]\sqrt{(x - 2)^2+ (y - 1)^2 + (z - 5)^2} = 2\sqrt{(x - 6)^2 + (y - 2)^2 + (z - 22)^2}[/tex]

Simplifying the equation, we have:

[tex](x - 2)^2 + (y - 1)^2 + (z - 5)^2 = 4((x - 6)^2 + (y - 2)^2 + (z - 22)^2)[/tex]

Expanding and combining like terms, we get:

[tex]3x^2 + 3y^2 + 3z^2 - 28x - 10y - 96z = 273[/tex]

This equation represents the equation of a sphere. The center of the sphere can be found by taking the average of the coordinates of points A and B, which gives us the center (4, 1.5, 13.5). The radius of the sphere is half the distance between points A and B, which is the square root of 273 divided by 2.

Therefore, the set of all points satisfying the given condition is a sphere with center (4, 1.5, 13.5) and radius √(273/2).

The probability that a randomly dealt 6-card hand contains all hearts is approximately 0.0000844, or about 0.00844%.

To calculate the probability of a randomly dealt 6-card hand containing all hearts, we need to determine the number of favorable outcomes and the total number of possible outcomes.

Favorable outcomes: A 6-card hand containing all hearts consists of 6 hearts from the deck.

There are 13 hearts in a standard deck of 52 cards, so we can choose 6 hearts from the 13 available. This can be calculated using combinations:

Number of favorable outcomes = C(13, 6) = 13! / (6! × (13 - 6)!) = 13! / (6! × 7!) = 1716

Total number of possible outcomes: The total number of 6-card hands that can be dealt from a standard deck of 52 cards is C(52, 6):

Number of possible outcomes = C(52, 6) = 52! / (6! × (52 - 6)!) = 52! / (6! × 46!) = 20358520

Therefore, the probability of a randomly dealt 6-card hand containing all hearts is:

Probability = Number of favorable outcomes / Number of possible outcomes = 1716 / 20358520 ≈ 0.0000844

So, the probability is approximately 0.0000844, or about 0.00844%.

The probability of winning at least one prize when buying one ticket each month for 5-months is (c) 0.44.

In order to calculate the probability of winning at least one prize when buying one ticket each month for five months, we use the complement rule. The complement of winning at least one prize is not winning any prize.

The probability of not winning any prize in a single month is 1 - 0.11 = 0.89 (because the probability of winning a prize is given as 0.11),

Since the events of not winning a prize in each month are independent, the probability of not winning a prize in all five months is (0.89)⁵,

So, the probability of winning at least one prize is 1 - (0.89)⁵ ≈ 1 - 0.5570 ≈ 0.443 ≈ 0.44,

The linear feet of steel cable that can be produced is approximately 1,469 feet.

To find the linear feet of steel cable that can be produced, we need to calculate the volume of the block of steel and then consider the efficiency of the extrusion process.

1. Cross-sectional area of the block:

Cross-sectional area = (16 in.) * (16 in.) = 256 in²

Converted to square feet: 256 in² * 0.00694 ft²/in² = 1.77778 ft²

2. Volume of the block:

Volume = Cross-sectional area * Length = 1.77778 ft² * 10 ft = 17.7778 ft³

3. Usable volume after considering the efficiency:

Usable volume = Efficiency * Volume = 0.94 * 17.7778 ft³ = 16.7044 ft³

4. Cross-sectional area of the cable:

Cross-sectional area = π * (0.85 in.)²

Converted to square feet: Cross-sectional area = π * (0.85 in.)² / 144 in²/ft²

5. Linear feet of steel cable produced:

Linear feet = Usable volume / Cross-sectional area of the cable

Linear feet = 16.7044 ft³ / (π * (0.85 in.)² / 144 in²/ft²) = 1468.672 ft

Rounded to the nearest foot, the result is approximately 1,469 feet.

It is proved that if f has a zero at 0 and if Ref(z) > 0 for every ze aD(0; 1), then f has a pole in D(0; 1).

The problem is based on Complex Analysis.

Let U CC be a region containing D(0; 1) and let f be a meromorphic function on U, which has no zeros and no poles on aD(0; 1).

If f has a zero at 0 and if Ref(z) > 0 for every ze aD(0; 1), we need to prove that f has a pole in D(0; 1).

We know that f is meromorphic function on U and we are given that it has a zero at 0. So, we can write the Laurent expansion of f around 0 as: f(z) = anzn+ ... + a1z + a0 + b1z + ... where an ≠ 0 and the expansion is valid in a deleted neighborhood of z=0. This implies that f(z) has a pole of order m at 0 where m is the largest non-negative integer such that am ≠ 0.

Suppose that m = 0 and f(z) has a removable singularity at 0 then by Riemann’s theorem f(z) is bounded in some deleted neighborhood of z = 0 which implies that Ref(z) ≤ M, a contradiction to Ref(z) > 0 for every ze aD(0; 1).

Hence, f(z) has a pole at 0. Therefore, f has a pole in D(0; 1). Hence, we have proved that if f has a zero at 0 and if Ref(z) > 0 for every ze aD(0; 1), then f has a pole in D(0; 1).

Step-by-step explanation:

The variable x represents how many board games were in Anne's cabinet to start. Since she has already picked out 3 board games to bring, the expression x–3 represents how many board games are still in the cabinet.

And, since Anne has more than 10 board games still in her cabinet, x–3 must be greater than 10.

This inequality shows the relationship.

x–3>10

Now, solve for x.

x–3

Sum of two interiors =Exterior

Use simple way

Angle beside x

Measure of x

Answer:

x = 44°

Step-by-step explanation:

According to the Exterior Angle Theorem of a triangle, the external angle is equal to the sum of the two interior opposite angles of a triangle.  

This is because the interior angles of a triangle sum to 180° and angles on a straight line sum to 180°.

⇒ x = ∠CAB + ∠BCA

⇒ x = 14° + 30°

⇒ x = 44°

Proof

Interior angles of a triangle sum to 180°

⇒ ∠CAB + ∠ABC + ∠BCA = 180°

⇒ 14° + ∠ABC + 30° = 180°

⇒ ∠ABC = 180° - 14° - 30°

⇒ ∠ABC = 136°

Angles on a straight line sum to 180°

⇒ ∠ABC + x = 180°

⇒ 136° + x = 180°

⇒ x = 180° - 136°

⇒ x = 44°
