The equation of distance traveled by the car is d(t) = 60 · t, for t ≥ 0.

In accordance with the statement, car travels in a straight line at constant speed. The distance traveled (d), in miles, is equal to the product of the speed (v), in miles per hour, and time (t), in hours:

d(t) = v · t     (1)

If we know that v = 60 mi/h, then the equation of distance traveled by the car is d(t) = 60 · t, for t ≥ 0.

The statement is incomplete and complete form cannot be found. Then, we decided to complete the statement by asking for the equation that describes the distance of the car.

The function is continuous on set of real numbers. Therefore, the correct answer is A) F is continuous on the set of real numbers.

To determine where the function F(x, y) is continuous, we need to check if the function is defined and the limit exists at every point in its domain.

The function is defined for all (x, y) except where the denominator 2 + e^(x - y) is equal to zero, which is only when e^(x - y) = -2, which has no real solutions. Therefore, domain of F is all real numbers.

Now, we need to check if the limit exists at every point in its domain. We can start by checking the limit as (x, y) approaches (a, b) for arbitrary constants a and b.

lim (x,y)->(a,b) F(x,y) = lim (x,y)->(a,b) [(xy)/(2+e^(x-y))]

To evaluate this limit, we can use the squeeze theorem, since 0 ≤ |xy| ≤ (1/2)(x² + y²), and both x² + y² and 2 + e^(x - y) approach zero as (x, y) approaches (a, b). Therefore, we can say that:

0 ≤ |F(x,y)| ≤ [(1/2)(x² + y²)] / [2 + e^(x-y)]

And by the squeeze theorem, as (x, y) approaches (a, b), F(x, y) approaches zero.

Since the limit of F(x, y) exists at every point in its domain, we can conclude that the function is continuous.

Triangle KVM is similar to triangle BVG because angle M = angle G = 90° and angle V is common to both triangles.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio.

For two triangles to be similar, the corresponding angles must be congruent i.e equal.. Also the ratio of the corresponding sides of similar triangles are equal.

angle M and G are both 90° , this means they are equal.

angle KVM = BVG

therefore angle K = angle B

Since all the corresponding angles are equal, we can say triangle KVM is similar to triangle BVG

To find the value of x in the equation, we can compare the exponents on both sides.

On the left side, we have (a/b)^(2/3).

On the right side, we have (a/b)^x.

To make the exponents on both sides match, we can equate them:

2/3 = x.

Therefore, the value of x is 2/3.

None of the provided options match the value of x as 2/3. If those are the only options given, then none of them are correct for the equation.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

For a given right triangle, the expression is,

⇒ sin (3x - 7) = cos (x + 1)

Now,

Solve for x as;

The expression is,

⇒ sin (3x - 7) = cos (x + 1)

Since, sin x= cos (90 - x)

So, We get;

⇒ sin (3x - 7) = cos (x + 1)

⇒ cos (90 - (3x - 7)) = cos (x + 1)

⇒ 90 - (3x - 7) =  (x + 1)

⇒ 90 - 3x + 7 = x + 1

⇒ 97 - 3x = x + 1

⇒ 97 - 1 = x + 3x

⇒ 96 = 4x

⇒ 4x = 96

⇒ x = 96/4

⇒ x = 24

Thus, The value of x will be 24.

The value of log7 base 10 is 0.84509804.The logarithm of a number is the exponent to which another fixed number (in this case 10) must be raised to produce that number.

The logarithm of a number is the exponent to which another fixed number (in this case 10) must be raised to produce that number. So to find the logarithm of 7 base 10, we must find the exponent to which 10 must be raised to produce 7. This can be solved using a calculator by taking the logarithm of 7 (log 7) and setting the base to 10 (log 10). The answer is 0.84509804. This means that 10 must be raised to the power of 0.84509804 to produce 7.

All of the statements are false except statement d. Counter-examples are given for each false statement each and explained below.

a) The statement is incorrect because there may exist elements in set B that are not included in the union of sets A and B.

Counter-example: if we take A as {1} and B as {2}, we can see that B is not part of the union of A and B, denoted as A ∪ B.

(b) The statement is incorrect because the union of sets A and B can include elements that are not in set A.

Counterexample: Let A = {1} and B = {2}. Then (A ∪ B) = {1, 2}, and {1, 2} is not a subset of A since it contains an element (2) that is not in A.

(c) The statement is false because removing set B from the union of sets A and B may result in elements that are not present in set A.

Counterexample: Let A = {1} and B = {2}. Then (A ∪ B) - B = {1} - {2} = {1}, which is not equal to A.

(d) The statement is true because removing the set A from the set B minus A will result in set A itself.

(e) The statement is false because there can be cases where sets A, B, and C have overlapping elements, indicating that A is not disjoint from C.

Counterexample: Let A = {1}, B = {2}, and C = {1, 2}. Then A + B = {1, 2} and B + C = {1, 2}, but A ∩ C = {1} is not an empty set, so A and C are not disjoint.

Step-by-step explanation:

-6(-4 + 25)

24-150

Answer:

-126

Step-by-step explanation:

First, you multiply the -6 by -4

-6 * -4 = 24

Because a negative times a negative equals a positive.

So you now have 24

Second, you multiply the -6 times 25

-6 * 25 = -150

Because a negative times a positive is a negative.

So now you have -150

Third, you add up the two numbers together

24 + -150 = -126

It follows from the task content that the number 9 × 10⁵ is to be compared to 5 × 10³ and determine how larger it is.

On this note, to determine how large 9 × 10⁵ is compared to 5 × 10³; we have that;

(9 × 10⁵) / (5 × 10³)

= (9/5) × (10⁵/10³)

The aggregate forwarding rate of peer i is equal to ri * (N - 1), which depends on the values of ui, us, and UP.

The aggregate forwarding rate of peer i is equal to ri * (N - 1). This is because each peer is forwarding the bits it receives to each of the other (N-1) peers at the rate of ri. Therefore, the aggregate forwarding rate of peer i is equal to ri multiplied by (N-1), which is equal to (u:/UP)* us * (N - 1). Whether the aggregate forwarding rate is bigger or smaller than the maximum upload rate ui depends on the values of ui, us, and UP. If ui is larger than (u:/UP)* us * (N - 1), then the aggregate forwarding rate is smaller than the maximum upload rate ui. On the other hand, if ui is smaller than (u:/UP)* us * (N - 1), then the aggregate forwarding rate is bigger than the maximum upload rate ui.
