Answer:

[tex]a_{n}[/tex] = - 3[tex](6)^{n-1}[/tex]

Step-by-step explanation:

Note the common ratio r between consecutive terms, that is

r = - 18 ÷ - 3 = - 108 ÷ - 18 = 6

This indicates the sequence is geometric with n th term ( explicit formula )

[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]

where a is the first term and r the common ratio

Here a = - 3 and r = 6, thus

[tex]a_{n}[/tex] = - 3[tex](6)^{n-1}[/tex]

Answer:

Angle Rome to Paris = 44.68°

Angle Paris to Berlin = 71.26°

Angle Berlin to Rome = 64.06

Step-by-step explanation:

See attachment for diagram illustration for this.

Let represent distance from Rome to Paris as a, distance from Paris to Berlin as b, and distance from Berlin to Rome as c.

Therefore we say

a = 697miles, b = 545miles, c = 734miles

To find the respectively angle formed from, Berlin to Paris to Rome, we will apply the cosine rule, which states that:

c² = a² + b² - 2abCosC

734² = 697² + 545² - 2(697*545)cosC

2(697*545)cosC = 697² + 545² - 734²

759739 cosC = 244078

cosC = 244078/759739

cosC = 0.3212

C = cos-¹0.3212

C = 71.26°

To get angle B, we will apply the sine rule, which states that:

a/sineA = b/sineB = c/sineC

Therefore we have

545/sineB = 734/sine71.26

= 545/sineB = 734/0.947

= 545/sineB = 734/0.947

= 545/sineB = 775.08

SineB = 545/775.08

B = sine-¹0.7032

B = 44.68°

Angle A = 180 - (B+C) angle in a triangle

A = 180 - (44.68 + 71.26)

A = 180 - 115.94

A = 64.06°

A = 64.06°

B = 44.68°

C = 71.26°

Angle Rome to Paris = 44.68°

Angle Paris to Berlin = 71.26°

Angle Berlin to Rome = 64.06°

Answer:

Step-by-step explanation:

The movement of the airplane can be represented using a triangle. In Triangle PRB, we are required to find Angles P, R and B.

Using Law of Cosines

[tex]cos R=\frac{p^2+b^2-r^2}{2pb} \\cos R=\frac{734^2+697^2-545^2}{2*734*697}\\R=arcCos\left(\frac{734^2+697^2-545^2}{2*734*697}\right)\\R=44.68^0[/tex]

Using law of Sines

[tex]\frac{r}{sin R}=\frac{p}{SIn P} \\\frac{545}{sin 44.68}=\frac{734}{Sin P} \\\text{Cross Multiply}\\545 X Sin P=734 X sin 44.68\\Sin P=\frac{734 X sin 44.68}{545} \\P=arcSin\left(\frac{734 X sin 44.68}{545}\right)\\P=71.26^0[/tex]

Now,

P+R+B=180 degrees (Sum of Angles in a Triangle)

[tex]71.26^0+44.68^0+B=180^0\\B=180^0-[71.26^0+44.68^0]\\B=64.06^0[/tex]

Answer:

4

Step-by-step explanation:

4 because 11x4=44

Flippin Middle School can buy at most 4 workbooks if it has $44 to spend.

To determine the maximum number of workbooks that Flippin Middle School can buy with $44, we need to divide the total amount of money available by the cost of each workbook.

Let's denote the number of workbooks that can be bought as [tex]\( W \)[/tex], and we know that each workbook costs $11. Therefore, the total cost for [tex]\( W \)[/tex] workbooks would be [tex]\( 11W \)[/tex].

Given that the school has $44 to spend, we can set up the following inequality to find the maximum number of workbooks that can be purchased:

[tex]\[ 11W \leq 44 \][/tex]

Now, we divide both sides of the inequality by 11 to solve for [tex]\( W \)[/tex]:

[tex]\[ W \leq \frac{44}{11} \][/tex]

[tex]\[ W \leq 4 \][/tex]

Since [tex]\( W \)[/tex] must be a whole number because one cannot buy a fraction of a workbook, the maximum number of workbooks that Flippin Middle School can buy is 4.

Answer:

No

Step-by-step explanation:

The ratio 19:15 is equivalent to 19/15

19/15=1.26666

The ratio 4:3 is equivalent to 4/3

4/3=1.33333

1.26666 is not equal to 1.3333, so the ratios are not equivalent

Hope this helps! :)

Answer:

no

Step-by-step explanation:

cross multiply to check

19/15 and 4/3

multiply 19 x 3=57

multiply 4 x 15=60

since 57 and 60 aren't equal to each other then the ratios aren't equivalent

Answer:

Step-by-step explanation:

Y = 3.2x + 5 is a linear function with slope 3.2 and y-intercept 5.

For any x value you choose to substitute for x, you'll obtain a unique y value.  For example, if we were to substitute -3 for x, we'd get:

f(-3) = y = 3.2(-3) + 5, or y = -9.6 + 5 = -4.6

There is only one y result for each choice of x.  

Y=3.2x+5 alone does not have an "answer."  Again:  You must pick your own x values and for each such value you must calculate y.

Answer:

25.

Step-by-step explanation:

If an expression is  

[tex]x^2+bx[/tex]

then we have to add [tex](\frac{b}{2})^2[/tex], to make it perfect quare.

The given expression is

[tex]x^2+10x[/tex]

Here, b=10.

[tex](\frac{b}{2})^2=(\frac{10}{2})^2=5^2=25[/tex]

Now,

[tex]x^2+10x+25=x^2+2x(5)+5^2=(x+5)^2[/tex]

Therefore, we need to add 25 to make it perfect square.

Answer:

All real numbers greater than 0

Step-by-step explanation:

A function assigns values. The range of the function will be all real numbers greater than 0.

A function assigns the value of each element of one set to the other specific element of another set.

As we can see in the function x can take up any value from -∞ to +∞. Although the value of eˣ will still be positive for any value of x.

Thus, the range of the function will be all real numbers greater than 0.

(22, 9)

Step-by-step explanation:

The positive difference of two integers is 13. The sum of the larger number and the square of the smaller is 103. Give your solution(s) as ordered pair (larger, smaller).    I'll call the two integers a and b.

a - b  =  13        a + b² = 103

  +b     +b

a   =  13 + b    plug this into the second equation

a + b² = 103

(13+b) + b²  = 103    subtract 103 from both sides to get one side equal to zero

-103              -103

b² + b - 90 = 0      what factors (two numbers multiply) to -90 that also add up

                             to 1? The only two that work are -9 and 10.  

(b-9)(b+10) = 0      so  b-9 = 0     or    b+10 = 0

                                     +9  +9    or       -10   -10

                                     b = 9      or    b = -10 but both numbers must be positive

b = 9  and a = 13 + b so   a = 13 + 9 = 22

Answer:

Less than or equal to $80

Step-by-step explanation:

If she get $320 a month and shops 4 times a month, you have to find the unit rate. This is so that you know the maximum amount of money she can spend.

320÷4=80

She can't go above $80, but she can spend any amount under $80. Than means the amount she can spend is less than or equal to $80.

The inequality that can be used to find the possible values of x is x≤80.

Maximum budget per month =$320

Number of times Ms Sung goes to a shop a month = 4

Amount spent on each shopping trip = x

Inequality is a statement that equates to two expressions.

So, the amount spent on 4 shopping trips = 4x

The maximum amount she can spend on all trips=$320

This means, [tex]4x\leq 320[/tex]

So, [tex]x\leq 80[/tex]

Hence, the inequality that can be used to find the possible values of x is x≤80.

$1085.00

Step-by-step explanation:

The maximum FUTA deductions for the first quarter is $1050.

The percentage means the required value out of 100.

It is calculated by dividing the required value by the total value and multiplying it by 100.

The percentage change is also calculated using the same method.

In percentage change, we find the difference between the values given.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

The Federal Unemployment Tax Act (FUTA) tax rate is 6% of the first $7,000 paid to each employee per year.

So,

For person 1:

The FUTA tax is 6% of $3500 = $210.

For person 2:

The FUTA tax is 6% of $7000 = $420

Since the FUTA tax is limited to $7000 of wages per employee per year.

For person 3:

The FUTA tax is 6% of $7000 = $420.

Since the FUTA tax is limited to $7000 of wages per employee per year.

The maximum FUTA deduction would be the sum of the FUTA tax for each employee.

= $210 + $420 + $420

= $1050.

Therefore,

The maximum FUTA deductions for the first quarter is $1050.
