Sandra wrote the sequence shown:
7, 14, 25, 40, 59
Complete each of the 2 activities for this Task.
Activity 1 of 2
What explicit expression can be used to find the nth term of this sequence?

Answers

Answer:

2n^2 + n + 4.

Step-by-step explanation:

7, 14, 25, 40, 59

The differences  are 7, 11, 15, 19 which is  arithmetic sequence so the given sequence is quadratic.

Compile a table:

n                     1      2      3      4      5

term               7    14    25    40    59

Diff:                    7      11     15     19

Diff:                      4       4      4            - this indicates that first part is 2n^2.

2n^2               2    8    18    32     50

term-2n^2      5    6    7     8        9

- the nth term for the last sequence is  5+ (n - 1)d =  

= 5 + (n - 1)* 1

= n + 4.

So nth term for the original sequence is 2n^2 + n + 4.

Write an equation, in standard form, using the following given info: M = 10
and it passes through the point (6,2) *
-10x + y = -58
-10x + y = 58. -10x - y = -58
10x + y = -58

Answers

Given:

m = 10

The line passes through the point (6,2).

To find:

The equation of line in the standard form.

Solution:

If a line passes through the point [tex](x_1,y_1)[/tex] with slope m, then the equation of line is

[tex]y-y_1=m(x-x_1)[/tex]

The line passes through the point (6,2) and m = 10. So, the equation of line is

[tex]y-2=10(x-6)[/tex]

[tex]y-2=10x-60[/tex]

[tex]y-10x=-60+2[/tex]

[tex]-10x+y=-58[/tex]

Therefore, the correct option is A.

The simplified version of this x-2z

Step-by-step explanation:

You need to start by combining like terms. You can start with the terms that have the variable x in them. By combining those terms, the equation becomes x+3y-z-3y-z.

From here, you can combine the terms 3y and -3y, which bring the equation to x-z-z.

From here, combine the terms with the variable z. This would bring the equation down too x-2z, your final answer.

Answer:

[tex]y = 5 + x[/tex]

[tex]y - x = 5[/tex]

[tex]x = y - 5[/tex]

Step-by-step explanation:

No options were given but the question can still be solved

Given

From the first statement, we have:

[tex]Maria = x[/tex]

From the second, we have:

[tex]Anika = 5\ more[/tex]

Required

Determine the relationship between the amount of rice they bought

5 more means 5 + Maria.

So, [tex]Anika = 5\ more[/tex] becomes

[tex]Anika = 5 + Maria[/tex]

Substitute x for Maria

[tex]Anika = 5 + x[/tex]

For proper expression, let Anika be y

[tex]y = 5 + x[/tex]

Subtract x from both sides

[tex]y - x = 5[/tex]

Make x the subject

[tex]x = y - 5[/tex]

Function 1 is defined by the equation p= --3/2r - 5. function 2 is defined by the following table. Which function has a greater y-intercept. A: Function 1 B: Function 2 C: The functions have the same y-intercept.

Answers

0-5. Here’s your answer

The y-intercept of function  1 is -5.

The y-intercept of function 2 is -5.

Option C is the correct answer.

What is a function?

function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

Consider the function to be in the form of p = mr + c

Where x is the y-intercept.

Function 1.

p = (-3/2)r - 5 _______(1)
y-intercept = -5

Function 2.
Let p = mr + c

Take two pairs from the table.

(0, -5) and (1, -6.5)

m = (-6.5 + 5) / (1 - 0) = -1.5

(0, -5) = (r, p)

-5 = -1.5 x 0 + c

c = -5

Now,

p = -5x - 5 ______(2)

y-intercept = -5

From (1 ) and (2)

Both have the same y-intercept.

Thus,

Function 1 and Function 2 have the same y-intercept.

An acting school claims that 71% of its graduates land major acting roles within one year of graduation. A random sample of 50 graduates was surveyed, and 30 of them had landed major roles within one year of graduation. Let p hat = the proportion of the sample who had landed major roles within one year of graduation.

The probability that 60% or fewer graduates land a major acting role within one year of graduating from this school is 0.043. Does this result provide convincing evidence against the school’s claim?

A. Yes, it is expected that at least 60 graduates from this school will land a major role within one year of graduation.

B. Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely (0.043 < 0.05).

C. No, the difference between the sample proportion and the parameter is 11%, which is greater than 5%.

D. No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely (0.043 < 0.05).

Tory read her book and rate of 4/5 of a chapter her 2/3 of an hour. How many chapters can she read in one hour

Answers

Answer: She can read 1.2 chapters of her book in one hour.

Step-by-step explanation:

When we have a relation of: "doing something" in a given "amount of time"

The rate at which you can do that activity per unit of time is:

R = (how much you did)/(time it took)

In this case, we know that

"Tory reads 4/5 of a chapter in 2/3 of an hour"

Then the rate, in this case, could be calculated as:

R = (4/5 chapters)/(2/3 hour) = 1.2 chapter per hour.

This means she can read 1.2 chapters of her book in one hour.

In a right angled triangke abc the perpendicular and the base measure 3 cm find hypotenus and three trignometrice ratios

Answers

Given:

In a right angled triangle ABC the perpendicular and the base measure 3 cm.

To find:

The hypotenuse and three trigonometric ratios.

Solution:

Pythagoras theorem:

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

Use Pythagoras theorem in triangle ABC.

[tex]Hypotenuse^2=(3)^2+(3)^2[/tex]

[tex]Hypotenuse^2=9+9[/tex]

[tex]Hypotenuse=\sqrt{18}[/tex]

[tex]Hypotenuse=3\sqrt{2}[/tex]

The three trigonometric ratios are

[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]

[tex]\sin \theta=\dfrac{3}{3\sqrt{2}}[/tex]

[tex]\sin \theta=\dfrac{1}{\sqrt{2}}[/tex]

Similarly,

[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]

[tex]\cos \theta=\dfrac{3}{3\sqrt{2}}[/tex]

[tex]\cos \theta=\dfrac{1}{\sqrt{2}}[/tex]

And,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

[tex]\tan \theta=\dfrac{3}{3}[/tex]

[tex]\tan \theta=1[/tex]

Therefore, the hypotenuse is [tex]3\sqrt{2}[/tex] cm and three trigonometric ratios are [tex]\sin \theta=\dfrac{1}{\sqrt{2}}, \cos \theta=\dfrac{1}{\sqrt{2}}, \tan \theta=1[/tex].

YVZ and ZVT are not straight lines together.

XVW and WVU are on the same straight line but you have to add UVT in order to get 180.

Lisa and Cory are having a debate about gravitation. Lisa says that the astronauts in that international Space Station (which is a distance of about 6800 km from Earth’s center) are too far away from Earth to experience Earth’s gravitational pull, and that is why they float. Cory insists that Lisa is incorrect. Which of them is correct in their statement, and why?

Answers

Answer:

Only Cory is correct

Step-by-step explanation:

The gravitational pull of the Earth on a person or object is given by Newton's law of gravitation as follows;

[tex]F =G\times \dfrac{M \cdot m}{r^{2}}[/tex]

Where;

G = The universal gravitational constant

M = The mass of one object

m = The mass of the other object

r = The distance between the centers of the two objects

For the gravitational pull of the Earth on a person, when the person is standing on the Earth's surface, r = R = The radius of the Earth ≈ 6,371 km

Therefore, for an astronaut in the international Space Station, r = 6,800 km

The ratio of the gravitational pull on the surface of the Earth, F₁, and the gravitational pull on an astronaut at the international space station, F₂, is therefore given as follows;

[tex]\dfrac{F_1}{F_2} = \dfrac{ \dfrac{M \cdot m}{R^{2}}}{\dfrac{M \cdot m}{r^{2}}} = \dfrac{r^2}{R^2} = \dfrac{(6,800 \ km)^2}{(6,371 \ km)^2} \approx 1.14[/tex]

∴ F₁ ≈ 1.14 × F₂

F₂ ≈ 0.8778 × F₁

Therefore, the gravitational pull on the astronaut by virtue of the distance from the center of the Earth, F₂ is approximately 88% of the gravitational pull on a person of similar mass on Earth

However, the International Space Station is moving in its orbit around the Earth at an orbiting speed enough to prevent the Space Station from falling to the Earth such that the Space Station falls around the Earth because of the curved shape of the gravitational attraction, such that the astronaut are constantly falling (similar to falling from height) and appear not to experience gravity

Therefore, Cory is correct, the astronauts in the International Space Station, 6,800 km from the Earth's center, are not too far to experience gravity.
