week to her account.
1. At the end of 4 weeks, who has more money in their account?

The airplane that descends at a rate of 2,700 feet per minute, after 3 1/2 minutes it will be at 9450 ft

The formula and procedure we will use to solve this problem is:

v= x/t

Where:

Information about the problem:

Converting the mixed fraction to a fraction, we get:

3 1/2 =

[(3*2) + 1]/2 =

(6+1) / 2 =

7/2

3 1/2 min is equivalent to 7/2

Applying the velocity and isolating the distance we have:

x= v*t

x = 2700 ft/min * 7/2 min

x = 9450 ft

It is a physical quantity that indicates the displacement of a mobile per unit of time, it is expressed in units of distance per time, for example (miles/h, km/h).

Answer:

In this case the slope of a line perpendicular to the line whose equation is 12x+2y=-12 will be [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

A line has the form:

y = m * x + b

where:

In this case, the line has the form 12*x+2*y=-12

First, you must isolate the variable "y", in order to arrive at the form of the line detailed above:

12*x+2*y=-12

2*y= -12 -12*x

y= (-12 -12*x)÷2

y= (-12)÷2 -(12÷2)*x

y= -6 -6*x

In this case: the slope is -6 and the Y-intercept is -6.

Two lines are perpendicular when they form four equal 90º angles. For two lines to be perpendicular, they must have their slopes inverse and changed sign.

Then, in this case the slope of a line perpendicular to the line whose equation is 12x+2y=-12 will be [tex]\frac{1}{6}[/tex]

Answer: The answer is 6x–9, please mark me as brainliest and have a wonderful weekend. :D

Step-by-step explanation:

Answer:

y = 6x + 3

Step-by-step explanation:

Equation of the line

------------------------------------------------------

The equation of the line in slope-intercept form is:

y = mx + b

Being m the slope and b the y-intercept.

Where m is the slope and (h,k) is a point through which the line passes.

We are given the y-intercept as b=3 m=6.

Thus, the equation of the line is:

y = 6x + 3

The polynomial function has zeroes as given by x=0

In general, given zeroes of a polynomial function, a, b, c, and d, we can write the function as the multiplication of the factors

(x-a), (x-b), (x- c), and (x-d) then the degrees are 4

simply:

f(x)=(x-a) (x-b) (x- c) (x-d)

In this case, we can show that each of a, b, c, and d are zeroes of the function:

f(a)=(a-a) (a-b) (a-c) (a-d)

     = (0) (a-b) (a-c) (a-d)

     =0

f(b)=(b-a) (b-b) (b-c) (b-d)

      =(b-a) (0) (b-c) (b-d)  

      =0

f(c)=(c-a) (c-b) (c-c) (c-d)

     =(c-a) (c-b) (0) (c-d)

     =0

f(d)=(d-a) (d-b) (d-c) (d-d)

     =(d-a) (d-b) (d-c) (0)

     =0

since the value of the function at x=a, x=b, c, and d are equal to 0, then the function

f(x)=(x-a) (x-b) (x- c) (x-d) has zeroes at a, b, c and d

with the generalized form, we can substitute for the given zeroes,

x=-5, x=-2,0and 5 where a=-5, b=-2, c=0 and x=5

f(x)=(x-(-5)) (x-(-2)) (x-0) (x-5)

simplifying gives:

f(x)=(x+5) (x+2) x(x-5)

from here, we can put it in standard polynomial form by foiling the right side:

f(x)=x^3+2x^2-25x-50

To double-check the answer, just plug in the given zeroes, and ensure the value of the function at those points is equal to 0.

f (-5) =x^3+2x^2-25x-50

       =(-5)^3+2(-5)^2-2(-5)-50

f (-5) =0

f (-2) =(-2)^3+2(-2)^2-2(-2)-50

f (-2) =0

f (0) =0

f (5) =(5)^3+2(5)^2-2(5)-50

    =0

Hence, the function has zeroes as given by x=0.

Answer: [tex]\sqrt{170}[/tex]

Step-by-step explanation:

Distance formula: a^2+b^2=c^2 where c is the distance between two points

(-6-5)^2 + (4-(-3))^2=c^2

(-(6+5))^2 + (4+3)^2=c^2

(-11)^2 + 7^2=c^2

121 + 49=c^2

c^2=170

c=[tex]\sqrt{170}[/tex]   ==> distance between A and B

Answer:

x ≈ 14.7

Step-by-step explanation:

use pythagorean therorem

a^2 + b^2 = c^2

c is hypotenuse and we know the hypotenuse is 21

a^2 + b^2 = c^2

x^2 + 15^2 = 21^2

x^2 + 225 = 441

x^2 = 216

x = √216

x ≈ 14.7

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

Here, given the diagonals of the Rhombus, we want to get the length of one side of the Rhombus

We proceed to use the formula below;

d1 = √(4a^2-d2^2

Where d1 represents the length of one diagonal

a is the side of the Rhombus

d2 is the length of the second diagonal

Thus, mathematically;

d2^2 = 4a^2 - d1^2

4a^2 = d2^2 + d1^2

4a^2 = 18^2 + 24^2

4a^2 = 900

a^2 = 900/4

a^2 = 225

a = √225

a = 15

It is wrong. Because Verania has a comparative advantage in washing dishes, she should wash dishes, and Josimar should vacuum.

Having an absolute advantage in both things does not mean that Verania has a Comparative advantage in both as well.

They should find out which activity they both have a comparative advantage in and focus on that. The activity that costs the least opportunity cost is the one they have a comparative advantage.

Verania

Opportunity cost of vacuuming = 2 / 1 = 2 hours of washing dishes

Opportunity cost of washing = 1/2 = 0.5 hours of vacuuming

Josimar

The opportunity cost of vacuuming = 3/2 = 1.5 hours of washing dishes

Opportunity cost of washing = 2/3 = 0.66 hours of vacuuming

Verania has a comparative advantage in washing dishes while Josimar has a comparative advantage in vacuuming.

Answer:

b = 12

Step-by-step explanation:

subtract eight from both sides to leave the b variable on the left

b/2 = 14 - 8

b/2 = 6

multiply by 2 on both sides to leave b by itself

b = 6 * 2

b = 12

Answer:

12

Step-by-step explanation:

8 + b/2 = 14

b/2 = 14 -8

      = 6

b = 6 x 2
