Answer:

Step-by-step explanation:

To find the point at which the two plans cost the same, we can set their total costs equal to each other:

55 + 0.13x = 48 + 0.15x

Simplifying and solving for x, we get:

0.02x = 7

x = 350

Therefore, the plans will cost the same when Lisa drives 350 miles.

To find the cost at this point, we can substitute x=350 into either equation. Let's use the first plan:

Total cost = 55 + 0.13(350) = $97.50

Therefore, if Lisa drives 350 miles, the cost for either plan will be $97.50.

The solution of the given logarithm function log(f-3)-log(17-40) is

f < 3.

So no option is correct.

A logarithm function is a mathematical function that describes the relationship between a given number (called the argument or input) and a specified base. The logarithm of a number x with respect to a base b is the power to which b must be raised to give x.

In other words, if we have the equation y = log_b(x), then y represents the power to which the base b must be raised to get x. For example, if b=2, then log_2(8) = 3 because 2 raised to the power of 3 equals 8.

The given expression is:

log(f-3)-log(17-40)

We can simplify this expression using the property of logarithms:

log(a) - log(b) = log(a/b)

So, we get:

log((f-3)/(17-40))

Now, for this expression to have a real solution, the argument of the logarithm must be positive, so we have:

(f-3)/(17-40) > 0

Solving for f, we get:

f - 3 < 0 (since 17-40 is negative)

f < 3

Considering both functions, there are no restrictions or exclusions for any real number values in the domain. Therefore, the domain of the composition (f∘g)(x) is all real numbers.

To determine the domain of the composition (f∘g)(x), we need to consider the domains of both functions f(x) and g(x) and determine any restrictions.

The function f(x) =[tex]1x + 2[/tex] does not have any explicit restrictions on its domain. It is defined for all real numbers.

The function g(x) = [tex]x^2 - 2x[/tex] is a quadratic function. Quadratic functions are defined for all real numbers, so there are no restrictions on the domain of g(x).

When we compose functions, we need to ensure that the output of the inner function is within the domain of the outer function. In this case, the composition (f∘g)(x) means we substitute g(x) into f(x), resulting in f(g(x)).

Answer:

5 cm

Step-by-step explanation:

Given two sides of a right triangle, we can find the other side using the Pythagorean theorem, which is

[tex]a^2+b^2=c^2[/tex], where a and b are any of the two legs (e.g., you can set 12 can be a or b) and c is the hypotenuse.

If we allow 12 to b a and 13 to be c, we can solve for b, which is the measure of the other side:

[tex]12^2+b^2=13^2\\144+b^2=169\\b^2=25\\b=5\\b=-5[/tex]

When taking the square root of a number, you always get a negative number and a positive number, since squaring a negative gives a positive answer (e.g. 5^2 = 25 and (-5)^2 = 25).  However, because you can't have a negative answer, the answer is simply b = 5 cm

We can even check our answer by making sure that the sum of the square of the two legs equals the square of the hypotenuse:

Answer:

x = 3

y = 23

z = 4

Step-by-step explanation:

To find the values of x, y, and z in the rhombus, we need to use the properties of a rhombus. One of the properties of a rhombus is that its opposite angles are equal. Another property is that its diagonals are perpendicular bisectors of each other.

Let's label the vertices of the rhombus as A, B, C, and D, and the midpoint of diagonal AC as M. We can use the given information to write some equations:

First, we know that diagonal AC is perpendicular to diagonal BD, so we have:

-2x + 6 = 0

Solving for x, we get:

x = 3

Next, we know that diagonal AC bisects angle ACD, so we have:

y = 46/2 = 23

Now, we can use the fact that AM is the perpendicular bisector of CD to find z. Since M is the midpoint of AC, we have:

AM = MC

Using the distance formula, we can find the lengths of AM and MC in terms of z:

AM = sqrt((2z-8)^2 + (5y-4)^2)

MC = sqrt((8-2z)^2 + (5y-4)^2)

Setting these two expressions equal to each other, we get:

sqrt((2z-8)^2 + (5y-4)^2) = sqrt((8-2z)^2 + (5y-4)^2)

Simplifying this equation, we get:

4z - 16 = 16 - 4z

8z = 32

z = 4

Therefore, the values of x, y, and z are:

x = 3

y = 23

z = 4

So, the solution is x=3, y=23, and z=4.

based on the information provided, the probability of selecting a yellow disk is 1/5 or 0.2.

How to solve the problem?

The probability of selecting a yellow disk cannot be 2, as probabilities must always be between 0 and 1.

To calculate the probability of selecting a yellow disk, we can use the formula:

P(yellow) = number of yellow disks / total number of disks

From the information given, we know that there are 5 yellow disks and 25 total disks in the bag. Plugging these values into the formula gives:

P(yellow) = 5/25 = 1/5

Therefore, the probability of selecting a yellow disk is 1/5 or 0.2, which is a decimal value between 0 and 1.

It's possible that there was a typo in the original question or answer, or that some other context is missing which would make sense of the answer being 2. However, based on the information provided, the probability of selecting a yellow disk is 1/5 or 0.2.

Step-by-step explanation:

Since ABCD is a parallelogram, its opposite sides are parallel and congruent. Therefore, we have:

AB || CD and AB ≅ CD

AD || BC and AD ≅ BC

Since AC is a diagonal, it divides the parallelogram into two congruent triangles, namely, ΔABC and ΔACD. Therefore, we have:

∠A ≅ ∠D (corresponding angles of congruent triangles)

∠C ≅ ∠B (corresponding angles of congruent triangles)

AB ≅ CD (opposite sides of parallelogram)

AC ≅ AC (reflexive property of congruence)

Now, consider the triangles ΔAEC and ΔCEB. We have:

∠AEC ≅ ∠CEB (vertical angles)

∠ACE ≅ ∠BCE (corresponding angles of congruent triangles ΔABC and ΔACD)

AC ≅ AC (reflexive property of congruence)

Therefore, by the angle-angle-side (AAS) postulate, we can conclude that ΔAEC ≅ ΔCEB. Hence, we have:

CE ≅ AC (corresponding parts of congruent triangles)

BE ≅ DE (corresponding parts of congruent triangles)

Thus, we have proven that line segment AC is congruent to line segment CE, and line segment BE is congruent to line segment DE.

b) The customer can pay the company to collect 15 bins.

c) The customer can get approximately 16 bins (rounded to the nearest whole number) removed for $500 with a $30 tip included.

A) The direct variation equation to represent the cost would be y = kx, where y represents the cost, x represents the number of bins collected, and k is the constant of proportionality. In this case, since the cost is $33 for each bin collected, the value of k is 33. Therefore, the direct variation equation is y = 33x.

B) To find the number of bins a customer can pay the company to collect for $500, we can set the cost (y) equal to $500 and solve for x (the number of bins). Thus, we have:

y = 33x

500 = 33x

x = 500/33

x ≈ 15.15

Therefore, the customer can pay the company to collect 15 bins (rounded to the nearest whole number) for $500.

C) If the customer plans to tip the recycling company $30, the total cost would be $500 + $30 = $530. We can set the cost (y) equal to $530 and solve for x:

y = 33x + 30

530 = 33x + 30

500 = 33x

The probability of an event occurring is the fraction of the number of required outcome divided by the total number of possible outcomes.

The total possible outcome = 10

probability of generating 94 = 5/10 × 5/10 = 1/4

probability of generating an even number = 5/10 × 5/10 = 1/4 {all numbers ending with 0,2,4,6, and 8 must be even}

probability of generating an odd number = 0 {since the second digit must be from 0,2,4,6, and 8, hence no odd number can be generated}

probability of generating less than 32 = 2/10 × 2/10 = 1/25 {since the first digit must either be 1 or 3, while the second digit must be either 0 or 2}

probability of generating greater than 72 = 2/10 × 2/10 = 1/25 {since the first digit must either be 7 or 9, while the second digit must be either 6 or 8}.
