What is the value of 4(x - 2)(x + 3) + 7(x - 2)(x - 5) - 6(x - 3)(x - 5) when x = 5?

Answers

Answer:

96

Step-by-step explanation

4(x - 2)(x + 3) + 7(x - 2)(x - 5) - 6(x - 3)(x - 5)

4(5 - 2)(5 + 3) = 12(8) = 96

7(5 - 2)(5 - 5) = 0

- 6(5 - 3)(5 - 5)= 0

96+0-0 = 96

The slope of a line is ¾. A different line passes through the points (6, 3) & (-1, 5). Are the lines parallel? Why or why not?

Answers

Answer:

B. They are not parallel because their slopes are not equal.

Step-by-step explanation:

Find the slope of the line that runs through points (6, 3) and (-1, 5):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 - 3}{-1 - 6} [/tex]

[tex] slope (m) = \frac{2}{-7} = -\frac{2}{7} [/tex]

Since the slope of the line that passes through points (6, 3) and (-1, 5) is not the same with line that has a slope of ¾, therefore, both lines cannot be parallel.

The answer is "B. They are not parallel because their slopes are not equal."

The listed occupations of stockholders of a national computer company included 9% who were housewives. If six of these stockholders are randomly selected, what is the probability that none are housewives?

Answers

Answer:

no se la respuesta

Step-by-step explanation:

no se la respuesta

The probability that none of the six selected stockholders are housewives is,

⇒ 56.8%

The term probability refers to the likelihood of an event occurring. Probability means possibility.

The probability of an event occurring can be calculated by subtracting the probability of the event not occurring from 1.

Given that,

The listed occupations of stockholders of a national computer company included 9% who were housewives.

Since 9% of the stockholders are housewives.

Hence, the probability that a randomly selected stockholder is not a housewife is,

= [tex]1 - 9%[/tex]%

= [tex]1 - 0.09[/tex]

= [tex]0.91[/tex]

So, The probability that none of the six selected stockholders are housewives is,

⇒ [tex](0.91)^6[/tex]

⇒ [tex]0.5678[/tex]

Identify the holes, vertical asymptotes, and horizontal asymptotes of the following.


[tex]f (x) = \frac{2}{x-3}[/tex]

Answers

Answer:

Horizontal asymptote: y = 0

Vertical asymptote: x = 3

Step-by-step explanation:

The vertical asymptote in this graph would be when x = 3 because it would make the denominator 0, which would make the equation undefined.

There will not be any holes in the graph, because there won't be any point undefined in the function except for when x = 3, but that's a vertical asymptote.

Now, for the horizontal asymptote, we see what value y approaches as x approaches plus and minus infinity. Since x is in the denominator, y will approach 0 when it's plus or minus infinity.

Horizontal asymptote: y = 0

Vertical asymptote: x = 3

Determine the convergence or divergence of the sequence with the given nth term. If the sequence converges, find its limit. (If the quantity diverges, enter DIVERGES.) an

Answers

The sequence converges to a limit of 1/2.

We have,

Let's simplify the nth term of the sequence:

an = (n^2 + 3n) / (2n^2 + 5)

Dividing both the numerator and denominator by n^2, we get:

an = (1 + 3/n) / (2 + 5/n^2)

As n approaches infinity, the terms 3/n and 5/n^2 both tend towards zero.

Therefore, we have:

an = (1 + 0) / (2 + 0) = 1 / 2

The nth term of the sequence simplifies to a constant value of 1/2 as n approaches infinity.

Since the nth term converges to a specific value (1/2), the sequence itself is convergent.

The limit of the sequence is 1/2.

Thus,

The sequence converges to a limit of 1/2.

Q13. A stone is dropped from a height of 5 km. The distance it falls through varies directly with the
square of the time taken to fall through that distance. If it falls 64 min 4 seconds. find the distance the
stone covers in the 5th second?
A. 36 m
B. 58 m
C. 72 m
D. 100 m

Answers

I’m not sure but I think it might be C so sorry if it’s wrong

Answer:

The stone covers 36 m in the 5th second. Correct choice: A.

Step-by-step explanation:

Proportions

Two variables are said to be proportional if one of them can be calculated by multiplying the other by a constant of proportionality. If y and x are those variables, then:

y=k.x

There are other similar proportions where the relation is not linear. For example, if y is proportional to the square of x, then:

[tex]y=k.x^2[/tex]

According to the conditions of the question, the distance traveled by a stone dropped from a height of 5 Km varies directly with the square of the time taken to fall through that distance. If d is the distance and t is the time, then;

[tex]d=k.t^2[/tex]

To find the value of k, we use the given condition: The stone falls d=66 meters in t=4 seconds. Substituting:

[tex]64=k.4^2=16k[/tex]

Solving:

[tex]k=64/16=4[/tex]

Substitute the value of k into the equation to get the complete model.

[tex]d=4.t^2[/tex]

Now we calculate the distance when t=5 seconds:

[tex]d=4\cdot 5^2=4\cdot 25=100[/tex]

The stone has covered 100 m in 5 seconds. But we need to find the distance covered in the 5th second, that specific interval between 4 sec and 5 sec.

Since we already know the distance for t=4 sec (64 m), and the distance for t=5 sec (100 m), then:

distance in the 5th second = 100 m - 64 m = 36 m

The stone covers 36 m in the 5th second. Option A.

a chef has 5 5/8 pound beef filet. she slices the fillet into 8 ounce steaks A. how many pounds is each steak. write your answer as a fraction in simplest form. B. how many 8 ounce steaks can the chef create from the fillet? How many ounces of beef are left over​

Answers

Answer:

1/2 pound

90 ounces

11

Remaining 2 ounces

Step-by-step explanation:

Beef filet = 5 5/8 pounds

Slices of fillet = 8 ounces

A. how many pounds is each steak. write your answer as a fraction in simplest form.

1 pound = 16 ounces

Pounds of each steak = ounces per steak / ounces per pound

= 8 ounces / 16 ounces

= 1/2 pound

B. how many 8 ounce steaks can the chef create from the fillet? How many ounces of beef are left over

Beef filet = 5 5/8 pounds

= 45 / 8 pounds

Convert to ounces

= 90 ounces

Number of 8 ounces the chef can create = 90 ounces / 8 ounces

= 11.25

= 11

Remaining 2 ounces of beef

Answers

Answer:

Step-by-step explanation:

Since the Tootsie Roll lollipop is a sphere

volume of sphere= [tex]\frac{4}{3}piR^3[/tex] = -0.25 [tex]in^3/min[/tex]

the negative sign indicates that the volume is decreasing

upon differentiating

as the diameter given is =0.75 so radius will be = 0.375

[tex]dV/dt = 4piR^2*dR/dt[/tex]

so [tex]dR/dt = 0.25/4*3.14 *(0.375)^2[/tex]

So the radius is decreasing at the rate of dR/dt= 0.142in/min

Find the limit
(calculus)

Answers

Answer:

I believe [tex]\lim_{x \to a} f(x)[/tex] also equals 0.

Step-by-step explanation:

We know that g(x) has to be greater than or equal to 0. That means f(x) has to be smaller than g(x) or equal to 0.

If we plug in any value of x, f(x) will be positive because of the absolute value. The only way we are going to get f(x) smaller than g(x) or equal to g(x) is to have very small fractions.

Therefore, if [tex]\lim_{x \to a} g(x)=0[/tex], then [tex]\lim_{x \to a} f(x)=0[/tex] because f(x) must be smaller or equal to 0 as well.

Answer:

[tex]\displaystyle{ \lim_{x\to a}f(x)=0[/tex]

Step-by-step explanation:

The other user posted a great answer, but I would like to show you a more mathematical way!

We have [tex]|f(x)|\leq g(x)[/tex].

By the definition of absolute value, this is the same as saying:

[tex]f(x)\leq g(x)\text{ and } -f(x)\leq g(x)[/tex]

For the right, we can divide both sides by -1 to acquire:

[tex]f(x)\leq g(x)\text{ and } f(x)\geq- g(x)[/tex]

We can now combine them. This yields:

[tex]-g(x)\leq f(x)\leq g(x)[/tex]

Now, we can use the Squeeze Theorem (a.k.a. Pinch or Sandwich Theorem). The Squeeze Theorem posits that if we have:

[tex]g(x)\leq f(x)\leq h(x)[/tex]

And:

[tex]\displaystyle{ \lim_{x \to c} g(x)= \lim_{x \to c} h(x)=L}[/tex]

Then the following must be true:

[tex]\displaystyle{ \lim_{x \to c} f(x)=L[/tex]

We have:

[tex]-g(x)\leq f(x)\leq g(x)[/tex]

And we know that:

[tex]\displaystyle{ \lim_{x \to a} g(x)=0[/tex]

Then it follows that:

[tex]\displaystyle{ \lim_{x \to a} -g(x)=- \lim_{x \to a} g(x)=0[/tex]

Therefore, by using the Squeeze Theorem, we can conclude that:

[tex]\displaystyle{ \lim_{x\to a}f(x)=0[/tex]

And we're done!
