Answers

Answer 1

The mode of the ratio of the sequence should be greater than one for the divergence. Then the correct option is C.

What are sequence and series?

A series is a sum of sequence terms. That is, it is a list of numbers with adding operations between them.

We know that the condition of the converges of the series will be given as

[tex]\rm \Sigma ^{\infty}_{n=1} \ 0.2(-3)^{n-1}\ \ diverges \ because \ |r| > 1.[/tex]

The mode of the ratio of the sequence should be greater than one for the divergence.

Real world inequalities:

You must be 4 feet or taller to ride the roller coaster

Answers

[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]

The required inequality that represent the given scenario is :

[tex]\qquad \tt \dashrightarrow \:x \geqslant 4[/tex]

where, x is height in feet.

Let's interpret the information given:

4 feet or taller ⇒ the person can be 4 feet or above 4 feet

Let's set 'x' as the hypothetical height of a person

Therefore the inequality should be x ≥ 4

⇒ we put x as greater than 4 since the person must be taller than 4

feet to ride the roller coaster

⇒ we also put the '_' under the inequality to signify that the person

can equal 4 feet in height and still be eligible to ride the roller

coaster

They are each on a point on the grid. The points have coordinates written as (x,y).

The number horizontally, on the bottom of the grid are the x values. The numbers vertically, going up are the y-values.

So,

O has coordinates x = 1 and y= 1 so it will be (1,1)
E has coordinates x=1 and y = 11 so it will be (1,11)
T has coordinates x=2 and y = 5 so it will be (2,5)

Write an equation for each situation!

Alright, Nancy, let's do this.

If dimes are d, then quarters is d + 3.

10d + 25(d + 3) = 1090

I'm dealing with cents to get rid of the pesky decimal.

10d + 25d + 75 = 1090

35d = 1015

d = 29

Since quarters = d + 3, there are 32 quarters and 29 dimes.

What are the greatest common factors of 21 and 32?

Answers

Answer:

Step-by-step explanation:

The biggest common factor number is the GCF number. So the greatest common factor 21 and 32 is 1. Also check out the Least Common Multiple of 21 and 32

The greatest common factor of 21 and 32 is 1.

What is Greatest Common Factor?

Greatest common factor or GCF of two numbers is defined as the one common factor of the two given numbers which is the greatest of all the common factors.

GCF is also usually known as Highest Common Factor (HCF).

We have to find the greatest common factors of 21 and 32.

One of the method to find GCF is by prime factorization.

First prime factorize the two numbers. The product of the commonly shared prime factors will be the GCF.

If they don't share any common prime factors, then the GCF will be 1.

21 = 3 × 7

32 = 2 × 2 × 2 × 2 × 2

There are no common prime factors, GCF will be 1.

Hence, the greatest common factor of 21 and 32 is 1 since there are no common prime factors.

A ball is thrown from an initial height of 2 meters with an initial upward velocity of 15 m/s. The ball's height h (in meters) after t seconds is given by the following.

Answers

To find when the ball's height is
7
meters, we substitute
7
for
h
and solve for
t
.
=7+2−25t5t2
In order to solve for
t
, we first rewrite the equation in the form
=+at2+btc0
.
=+−5t225t50
Next, we use the quadratic formula to solve for
t
.
=t−b±−b24ac2a
Our equation has
=a5
,
=b−25
, and
=c5
.
Another way
We use these values in the formula.
t
=−−25±−−252·4·55·25
=25±52510
We get that
t
can be either of two values to solve the equation.
=t=−25525100.2087…
or
=t=+25525104.7912…
Rounding these values to the nearest hundredth, we get
=t0.21
or
=t4.79

So, the ball's height is
7
meters at approximately
0.21
seconds (on its way up) or

Which of these expresses the rate at which she is earning credits

Answer:

12 credits per semester

Step-by-step explanation:

she has 92 in the end but she started off with 8 so your first step is to subtract 8 from 92 which gives you 84 once you get 84 you divide that by 12 you get 7 which means she got 12 credits in each of her 7 semeters

Only elementary methods are allowed.

Answers

The first integral has a well-known beta function representation, so the second one should too. The beta function itself is defined as

[tex]B(x,y) = \displaystyle \int_0^1 t^{x-1} (1-t)^{y-1} \, dt[/tex]

and satisfies the identity

[tex]\displaystyle B(x,y) = \frac{\Gamma(x) \Gamma(y)}{\Gamma(x+y)}[/tex]

Later on, we'll also use the so-called reflection formula for the gamma function; for non-integer z,

[tex]\Gamma(z) \Gamma(1-z) = \dfrac{\pi}{\sin(\pi z)}[/tex]

as well as the identity

[tex]\dfrac{\Gamma(z+1)}{\Gamma(z)} = z[/tex]

Replace [tex]x\to\sin^{-1}(x)[/tex] in both integrals, so that

[tex]\displaystyle \int_0^{\frac\pi2} \sqrt{\sin(x)} \, dx = \int_0^1 \frac{\sqrt x}{\sqrt{1-x^2}} \, dx[/tex]

[tex]\displaystyle \int_0^{\frac\pi2} \frac{dx}{\sqrt{\sin(x)}} = \int_0^1 \frac{dx}{\sqrt x \sqrt{1-x^2}}[/tex]

Now replace [tex]x\to\sqrt x[/tex] :

[tex]\displaystyle \int_0^1 \frac{\sqrt x}{\sqrt{1-x^2}} \, dx = \frac12 \int_0^1 x^{-\frac14} (1-x)^{-\frac12} \, dx = \frac12 B\left(\frac34, \frac12\right) [/tex]

[tex]\displaystyle \int_0^1 \frac{dx}{\sqrt x \sqrt{1-x^2}} = \frac12 \int_0^1 x^{-\frac34} (1-x)^{-\frac12} \, dx = \frac12 B\left(\frac14, \frac12\right)[/tex]

So, the original integral (which I condense here to a double integral) is

[tex]\displaystyle \int_0^{\frac\pi2} \int_0^{\frac\pi2} \sqrt{\frac{\sin(x)}{\sin(y)}} \, dx \, dy = \frac14 B\left(\frac34, \frac12\right) B\left(\frac14, \frac12\right)[/tex]

[tex]\displaystyle = \frac14 \frac{\Gamma\left(\frac14\right) \Gamma\left(\frac34\right) \Gamma\left(\frac12\right)^2}{\Gamma\left(\frac54\right) \Gamma\left(\frac34\right)}[/tex]

[tex]\displaystyle = \frac14 \frac{\Gamma\left(\frac14\right) \Gamma\left(\frac34\right) \Gamma\left(\frac12\right)^2}{\frac14 \Gamma\left(\frac14\right) \Gamma\left(\frac34\right)}[/tex]

[tex]\displaystyle = \Gamma\left(\frac12\right)^2 = \frac{\pi}{\sin\left(\frac\pi2\right)} = \boxed{\pi}[/tex]

Answer:

266 miles

Step-by-step explanation:

Given statement

4 hours and 45 minutes

Clearly, 45 is 3/4th of an hour. Thus, this statement can also be written as:

⇒ 4 hours and 3(Hour)/4 minutes⇒ 4 hours + 3(Hour)/4 minutes⇒ 4 hours + 0.75(Hour)⇒ 4.75 hours

We are given that:

56 miles per hour

When we convert this statement into an equation, we get:

⇒ 56 miles = 1 hour

Multiply both sides by 4.75 to obtain the distance in 4.75 hours.

⇒ 56 × 4.75 miles = 1 hour × 4.75⇒ 266 miles = 4.75 hours
