3.4(x+1.58)= - 11.288

Step 1: Distribute 3.4 to the numbers inside the parentheses (x+1.58)

3.4x + (3.4×1.58)= - 11.288

3.4x + 5.372 = -11.288

Step 2: Bring 5.372 to the right side by subtracting it to both sides

3.4x + (5.372 - 5.372 ) = (-11.288 - 5.372)

3.4x + (0) = (-16.66)

3.4x = -16.66

Step 3: Isolate x by dividing 3.4 to both sides

[tex]\frac{3.4x}{3.4}  = \frac{-16.66}{3.4}[/tex]

x = -4.9

x= the amount of months passed

The question asks for the population of fleas in 1 year, and 1 year = 12 months, then x would equal 12 months

Therefore, you substitute that x with 12

f(x)=250(2^x)-------f(x)=250(2^12)

Now you can solve that part of the problem:

2 to the power of 12= 4096

f(x)=250(4096)

now multiply that:

250×4096= 1024000

The answer is C. 1024000

The answer is 1,024,000 fleas.

The function f(x)=250(2^x) gives the population of fleas after x months. To find out how many fleas there will be after 1 year, substitute x=12 into the function:
f(12) = 250(2^12) = 250 * 4096 = 1,024,000 fleas.

ANSWER

C. 145.75 yd²

EXPLANATION

First we need to calculate the area of the four triangular faces.

The lateral surface area

[tex] = 4 \times \frac{1}{2} \times 5.3 \times 11.1[/tex]

[tex] = 117.66 {yd}^{2} [/tex]

The area of the base is

[tex] = 5.3 \times 5.3[/tex]

[tex] = 28.09[/tex]

To find the total surface area, we add the area of the square base to the area of the 4 triangular faces.

Therefore the total surface area is

[tex] = 117.66 + 8.09 = 145.75 {yd}^{2} [/tex]

Answer: Option C.

Step-by-step explanation:

To calculate the surface area of the right square pyramid, you need to use the following formula:

[tex]SA=\frac{1}{2}(4s)(l)+(s^2)[/tex]

Where  "s" is the length of any side of the base and "l" is the slant height.

You can identify in the figure that:

[tex]s=5.3yd\\l=11.1yd[/tex]

Therefore, substituting these values into the formula, you get this result:

[tex]SA=\frac{1}{2}(4(5.3yd))(11.1yd)+((5.3yd)^2)\\\\SA=145.75yd^2[/tex]

Final answer:

The correct pair of points that is in the solution set for the given system of linear inequalities is option a) (0, 3/2) and (3/4, 1/4). Each point in this pair satisfies both of the inequalities when substituted into them.

Explanation:

The question asks which pair of points is in the solution set for the given system of linear inequalities:

2x + y < 2

6x + 3y > 2

To verify if the points provided are solutions, we plug them into the inequalities to see if they satisfy both conditions.

Let's test each pair:

For pair a) (0, 3/2), the first inequality becomes 2(0) + (3/2) = 3/2, which is less than 2, so it satisfies the first inequality. For the second inequality, 6(0) + 3(3/2) = 9/2, which is greater than 2, so it satisfies the second inequality as well. Therefore, (0, 3/2) is a solution. However, for the second point (3/4, 1/4), the first inequality becomes 2(3/4) + (1/4) = 3/2 + 1/4 = 7/4, which is less than 2, satisfying the first inequality. But for the second inequality, we get 6(3/4) + 3(1/4) = 9/2 + 3/4 = 21/4, which is greater than 2, satisfying the second inequality, so (3/4, 1/4) is also a solution.

For pair b), to be brief, one point does not satisfy both inequalities.

For pair c), one point does not satisfy both inequalities.

For pair d), one point does not satisfy both inequalities.

Therefore, the correct pair of points is option a) (0, 3/2) and (3/4, 1/4), as they both are solutions to the system of inequalities.

Step-by-step explanation:

Given

[tex]\sqrt{3x+8}[/tex] = [tex]\sqrt{4x+1}[/tex]

[ note that ([tex]\sqrt{x}[/tex])² = x ]

Square both sides

3x + 8 = 4x + 1 ( subtract 4x from both sides )

- x + 8 = 1 ( subtract 8 from both sides )

- x = - 7 ( multiply both sides by - 1 )

x = 7 → C

Answer:

Answer:

1/14

Step-by-step explanation:

The total number of coins in the bag is 10+6+5, or 21.

You reach into the bag and take ONE coin.  The chances of that being a nickel is 6/21, or 2/7, since nickels compose 6 of the 21 coins in the bag.

You don't replace the nickel.

Now you have 20 coins in the bag, including 5 nickels.

The chances of your next draw being a dime is 5/20, or 1/4, since there are 5 dimes in the bag.

The joint probability of drawing a nickel and then a dime is then the product of these two probabilities:

(2/7)(1/4) = 2/28 = 1/14

According to the information, it can be inferred that the current credit score for Esteban is 730 because he has not used more transactions than eleven of his credit score.

A credit score is a term that refers to an index that is intended to predict the chances that you will repay a loan on time.

This takes into account different factors related to your economy, so it is likely that the more movement of money you have, your score will be higher.

Based on the foregoing, it can be inferred that Esteban's score dropped because he has not made important transactions in recent months. Additionally, it has no recent transaction history.

Answer:

A

Step-by-step explanation:

Note that

x² + 12x + 36 is a perfect square → (x + 6)², hence

[tex]\sqrt{x^2+12x+36}[/tex] = [tex]\sqrt{(x+6)^2}[/tex] = (x + 6)

Hence

f(x) × g(x)

= (x + 6)(x³ - 11)

= [tex]x^{4}[/tex] - 11x + 6x³ - 66

= [tex]x^{4}[/tex] + 6x³ - 11x - 66 → A

(f·g)(x) in mathematics denotes the product of two functions, f(x) and g(x). Its interpretation and output may vary depending on the functions f(x) and g(x), but essentially, it is a multiplication of these two functions.

In mathematics, expressing (f·g)(x) indicates the product of two functions at a given x-coordinate. This is equivalent to f(x) multiplied by g(x). For instance, if f(x) = 2x and g(x) = 3x, then (f · g)(x) would yield (2x)(3x), resulting in 6x².

It's important to note that mathematical functions can vary, and this expression can take on various forms based on the nature of f(x) and g(x).

The provided reference information appears to be a mix of rules from differential calculus and mathematical definitions, which lack a direct relation to the original question about (f·g)(x). The primary concept here is understanding function multiplication.

[tex]\left\{x\in \mathbb {Z}\ : \ x \le 0 \right\}[/tex]

Step-by-step explanation:

Set-Builder Notation: A shorthand used to describe sets, often sets with an infinite number of elements.

The set {...,-3, -2, -1, 0} is the set of all negative integers and 0, so you can use such set-builder notation:

[tex]\left\{x\in \mathbb {Z}\ : \ x \le 0 \right\}[/tex]

Note: Here [tex]\mathbb{Z}[/tex] represents the set of all integers.

Final answer:

The set {... -3, -2, -1, 0} can be represented in set builder notation as {x ∈ ℤ | -3 ≤ x < 1 }, which describes all integers x that are greater than or equal to -3 and less than 1.

Explanation:

To express the set that includes the numbers -3, -2, -1, and 0 using set builder notation, we start by recognizing that these numbers can be described by a pattern or rule, which is that they are all the integer numbers greater than or equal to -3 and less than 1. We can then write this using set builder notation as:

{x ∈ ℤ | -3 ≤ x < 1 }

In this notation, the variable 'x' represents the elements of the set and ∈ stands for 'element of.' ℤ is the symbol for integers. The vertical bar or colon (|) stands for 'such that.' Our notation reads as 'the set of all integers x such that -3 is less than or equal to x and x is less than 1.'

Answer:

18 yds

Step-by-step explanation:

Let the length and width be L and W respectively.

Then L· W = area = 72 yd², so that L = (72 yd²) / W.

But also L = 3W + 6 yd.  Subbing this into  L· W = area = 72 yd², we get:

(3W + 6) · W = 72, or

3W² + 6W - 72 = 0.  Since all  four terms are evenly divisible by 3, we get:

W² + 2W - 24 = 0, which factors as follows:

(W + 6)(W - 4) = 0.  Then W + 6 = 0, or W = -6 (makes no sense for a length), and W - 4 = 0 yields W = 4 yds.

If the shorter side is of length 4 yds, then the longer side is of length

L = 3(4 yds) + 6 yds = 18 yds

Answer:

18 yd

Step-by-step explanation:

(3x + 6) * x = 72

Use the distributive property

3x^2 + 6x = 72

3x^2 + 6x - 72 = 0

3(x^2 + 2x - 24) = 0

X^2 + 2x - 24 = 0

X can equal -6 and 4.

4 only works for this problem

4 * 3 = 12

12 + 6 = 18

So, the answer is 18 yd.

Let’s check our work.

3 * 4 = 12

12 + 6 = 18

18 * 4 = 72

So, we know for a fact that the longer side is 18 yd long.

Final answer:

To solve the compound inequality, each inequality is solved individually. The first inequality yields x > 1.64285714, and the second yields x > -2.06666667. As this is an 'or' compound inequality, the solution is the union of both, leading to x > 1.64285714.

Explanation:

To solve the compound inequality 7x + 3/2 > 13 or 5/2x - 1/3 > -11/2, we need to treat each inequality separately and then find the union of their solutions.

For the first inequality:

Subtract 3/2 from both sides to get 7x > 11.5.

Divide both sides by 7 to find x > 11.5/7, which simplifies to x > 1.64285714.

For the second inequality:

Multiply both sides by 6 to clear the fraction, leading to 15x - 2 > -33.

Add 2 to both sides to get 15x > -31.

Divide both sides by 15 to find x > -31/15, which simplifies to x > -2.06666667.

The solution is the set that satisfies at least one of these inequalities. Since x > 1.64285714 or x > -2.06666667, the overall solution is x > 1.64285714.
