Y = 7/{3^(x+1)}

The number 7 is constant in the relation

The denominator is increasingly exponentially with the number 3 as i

The value of a is 2.

A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.

The figure given below shows a line segment FG, where the length of line segment FG refers to the distance between its endpoints, F and G.

Given that M is the midpoint of FG

FG = 14a + 1 and  FM = 14.5

FG = FM + MG

Since M is the midpoint of FG, So FM = MG

FG = FM + FM

FG = 2FM

Substitute the values of FG = 14a + 1 and  FM = 14.5,

14a + 1 = 2(14.5)

14a + 1 = 29

14a = 28

a = 28/14

a = 2

Therefore, the value of a is 2.

8 liters of 30 percent vinegar solution was mixed.

Percent or percentage is defined as the value for every 100. the simple way to calculate percentage is by dividing the data with the whole data and multiplying it by 100.

4 liters of 15 percent vinegar solution contains:

(15/100)×4 liters of vinegar=0.6 liters

x liters of 30 percent vinegar solution contains:

(30/100)× x liters of vinegar=0.03x liters

Therefore the total vinegar in the 25 percent solution is (0.6+0.3x) liters.

Total volume of the solution is (x+4) liters

(x+4) liters of 25 percent solution contains:

(25/100)×(x+4) liters =(0.25x+1) liters

Now we can equate both values to calculate the value of x from a linear equation:

(0.6+0.3x)=(0.25x+1)

or, 0.05x=1-0.6

or, x= 8 liters

Hence 8 liters or 30 percent solution was mixed.

Account Y would earn Monica about $62.70 more interest than account X.

Given Monica deposits $3000.

Bank offers two different savings accounts.

Account X pays 2.1% simple annual interest and Account Y pays 2.4% compounded annually, both for 5 years.

For account X, we have:

Principal (P) = $3000

time (t) = 5 years

rate of interest (r) = 2.1%

we need to calculate simple interest:

Simple interest = P×t×r/100

= 3000c5×2.1/100

= $315

simple interest for 5 years is $315

For account Y, we have:

Principal (P) = $3000

time (t) = 5 years

rate of interest (r) = 2.4%

we need to calculate Compound interest:

compound interest = P×(1₊rate)^time ₋ P

= 3000(1₊2.4/100)⁵ ₋ 3000

= 3000(1.024)⁵ ₋ 3000

= 3000(1.12589907) ₋ 3000

= 3377.69 ₋ 3000

= $377.69

The compound interest for 5 years is $377.7

compound interest of account Y ₋ simple interest of account X

= 377.7 ₋ 315

= $62.70

hence the right option is that account Y would earn Monica about $62.70 more interest than account X.

For less than 6 hours, Hank's Movers charge less.

Acme movers charge $210 plus $20 per hour, so if they work for x hours they charge:

A(x) = $210 + $20*x

Hank's movers only charge $55 per hour, so here the linear equation is:

H(x) = $55*x

They charge the same amount when:

A(x) = H(x)

$210 + $20*x = $55*x

Now we can solve that to get:

$210 + $20*x = $55*x

$210 = $55*x - $20*x = $35*x

$210/$35 = x = 6

So, for 6 hours, both companies charge the same amount.

For less than 6 hours, Hank's Movers charge less.

The perimeter of the right angled triangle is 24 units.

The perimeter is defined as the sum of all sides of a polygon. To calculate the perimeter of a triangle we add the length of all the 3 sides of the triangle.

The given side lengths are 6 and 8 units.

We know from Pythagorean theorem that for a right angled triangle the sum of the squares of the legs is equal to the square of the hypotenuse of the triangle.

Hypotenuse is the longest side in a right angled triangle.

Therefore the hypotenuse in this triangle is given by:

Hypotenuse² = 6² + 8²

or, hypotenuse = √(36 + 48) units

or, hypotenuse =√100

or, hypotenuse= 10 units

Now perimeter = (6 + 8 + 10) units = 24 units.

Hence the perimeter of the given right angled triangle is 24 units.

The factor which is used to convert feet per minute into miles per minute is:

1 ft per minute=0.000189 miles per minute.

( since, 1 ft.= 0.000189 miles )

Step-by-step explanation:

Conversion factor--

A conversion factor is a factor which is used to convert one unit to another by multiplication or division by a specified number.

We know that:

1 miles= 5280 ft.

This means that:

1 ft.=1/5280 miles

Answer:

y = 3x + 9

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 4 ← is in slope- intercept form

with slope m = 3

• Parallel lines have equal slopes , then

y = 3x + c ← is the partial equation of the parallel line

to find c substitute (1, 12 ) into the partial equation

12 = 3 + c ⇒ c = 12 - 3 = 9

y = 3x + 9 ← equation of parallel line
