Answer:

D

Step-by-step explanation:

Just subsititue the x-values into the equation to find the y :D

[tex]y=2x+1\\y=2(14)+1\\y=29\\y=2(18)+1\\y=37[/tex]

The equation that represents the sinusoidal function is [tex]x(t) = -8 + 6.5 \cdot \sin \left[\left(\frac{2}{3} \pm \frac{4\cdot i}{3}\right)\cdot t + \left(\frac{2\pi}{3} \pm \frac{7\pi \cdot i}{3} \right)\right][/tex], [tex]i\in \mathbb{Z}[/tex].

In this question we must find an appropriate model for a periodic function based on the information from statement. Sinusoidal functions are the most typical functions which intersects a midline ([tex]x_{mid}[/tex]) and has both a maximum ([tex]x_{max}[/tex]) and a minimum ([tex]x_{min}[/tex]).

Sinusoidal functions have in most cases the following form:

[tex]x(t) = x_{mid} + \left(\frac{x_{max}-x_{min}}{2} \right)\cdot \sin (\omega \cdot t + \phi)[/tex] (1)

Where:

If we know that [tex]x_{min} = -14.5[/tex], [tex]x_{mid} = -8[/tex], [tex]x_{max} = -1.5[/tex], [tex](t, x) = (-\pi, -8)[/tex] and [tex](t, x) = \left(\frac{\pi}{4}, -1.5 \right)[/tex], then the sinusoidal function is:

[tex]-8 +6.5\cdot \sin (-\pi\cdot \omega + \phi) = -8[/tex] (2)

[tex]-8+6.5\cdot \sin\left(\frac{\pi}{4}\cdot \omega + \phi \right) = -1.5[/tex] (3)

The resulting system is:

[tex]\sin (-\pi\cdot \omega + \phi) = 0[/tex] (2b)

[tex]\sin \left(\frac{\pi}{4}\cdot \omega + \phi \right) = 1[/tex] (3b)

By applying inverse trigonometric functions we have that:

[tex]-\pi\cdot \omega + \phi = 0 \pm \pi\cdot i[/tex], [tex]i \in \mathbb{Z}[/tex] (2c)

[tex]\frac{\pi}{4}\cdot \omega + \phi = \frac{\pi}{2} + 2\pi\cdot i[/tex], [tex]i \in \mathbb{Z}[/tex] (3c)

And we proceed to solve this system:

[tex]\pm \pi\cdot i + \pi\cdot \omega = \frac{\pi}{2} \pm 2\pi\cdot i -\frac{\pi}{4}\cdot \omega[/tex]

[tex]\frac{3\pi}{4}\cdot \omega = \frac{\pi}{2}\pm \pi\cdot i[/tex]

[tex]\omega = \frac{2}{3} \pm \frac{4\cdot i}{3}[/tex], [tex]i\in \mathbb{Z}[/tex] [tex]\blacksquare[/tex]

By (2c):

[tex]-\pi\cdot \left(\frac{2}{3} \pm \frac{4\cdot i}{3}\right) + \phi =\pm \pi\cdot i[/tex]

[tex]-\frac{2\pi}{3} \mp \frac{4\pi\cdot i}{3} + \phi = \pm \pi\cdot i[/tex]

[tex]\phi = \frac{2\pi}{3} \pm \frac{7\pi\cdot i}{3}, i\in \mathbb{Z}[/tex] [tex]\blacksquare[/tex]

The equation that represents the sinusoidal function is [tex]x(t) = -8 + 6.5 \cdot \sin \left[\left(\frac{2}{3} \pm \frac{4\cdot i}{3}\right)\cdot t + \left(\frac{2\pi}{3} \pm \frac{7\pi \cdot i}{3} \right)\right][/tex], [tex]i\in \mathbb{Z}[/tex]. [tex]\blacksquare[/tex]

Answer:

There are 24 total possible outcomes

Step-by-step explanation:

We can see that there are 3 ways to choose a suit, 2 ways to choose a wig, and 4 ways to choose a talent. The Fundamental Counting Principle tells us that the total number of possible outcomes is determined by multiplying the possible ways in each category with each category themselves.

Therefore, 3*2*4=24, which means that there are 24 ways to choose a suit, wig, and talent for a clown

Answer:

The answer is 24

Answer:

20 17/25

Step-by-step explanation:

8/9 of 64 = (8 × 64) ÷ 9

(8 × 64) ÷ 9 = 56 8/9

56 8/9 is the same as 512/9 (multiply 56 and 9, then add 8)

4/11 of 512/9 = 512(4)÷11(9)

= 2048/99

= 20 68/100 which reduces to 20 17/25

Answer:

N=14

Step-by-step explanation:

The first thing you want to do is write 2016 as its prime factorization: 2016 = 25*32*7. The 32 is already a square. We need too multiply one more factor of 2 to make 26, which has 23 = 8 as its square root. We also need to multiply by 7 to give 72. Therefore, to make a perfect square out of 2016, we need to multiply by 2*7 = 14. So, N  =14.

Answer:

Money with Mary = $28

Money with Vivan = $12

Step-by-step explanation

Money with Mary = $ m

Money with Vivan = $v

If mary gave vivan $8 they would have same amount. $ 8 is reduced from Mary's amount 'm' and $8 is added  to vivan amount 'v'

m - 8 = v + 8

m = v + 8 +8

m -v = 16     ----------------(I)

If vivan gives mary $8, then mary would have 9 times as much as vivan.

9(v - 8) = m + 8

9v - 72 = m + 8

9v - m = 8 + 72

-m + 9v = 80 --------------(II)

Add equation (I) and (II). Thus m  will be cancelled and we will get the value of v

(I)       m - v  = 16

(II)    -m  + 9v = 80 {Now add}

               8v = 96

                 v = 96/8

v = $ 12

Plugin v = 12 in equation (I)

m - 12 = 16

m = 16 +12

m =$ 28

Factorization; a factor is a number that divides a specified number exactly, and a multiple is a number that is multiplied by another to get the progression of a particular number.

Give the student a target number and ask them to put a "1x" below it. Ask them to fill in the number on the right side. We know that every number has a "factor pair" that is one times it's own.

Based on the information given the amount due on a $300 invoice received on June 3 is $291.

Using this formula

Amount due=Invoice amount-(Invoice amount×Sales percentage)

Where:

Invoice amount=$300

Sales percentage=3%

Let plug in the formula

Amount due=$300-($300×3%)

Amount due=$300-$9

Amount due=$291

Inconclusion the amount due on a $300 invoice received on June 3 is $291.
