The balance owed on the credit card if the growth is exponential according to the equation is; $57,528.

It follows from the task content that the initial amount owed was; $800.

On this simple note, since the equation given in the task content for the exponential growth from above is;

f(x)=800(1+0.13)^x

So therefore, when x = 34.9 months; we then have;

f(x)=800(1+0.13)^34.9

f(x) = 800(1.13)^34.9

f(x) = 800 × 71.19

The right answer for the value of x is 4

Let us consider the small triangle to be ABC and the larger triangle to be ADE

where angle A is the common angle of both the triangle

By triangle proportionality theorem,

If a line parallel to one side of a triangle intersects the other two sides, the two sides are proportionally divided.

Thus line BC is parallel to DE and hence divides AB and AD as well as

AC and AE proportionally

Thus Triangle ABC is Similar to triangle ADE by SAS

Thus,

AB/BD=BC/DE=AC/CE

Thus, using AB/BD=AC/CE

it is given that AB=10,BC=7x-3,AC=8,CE=28-8=20

AB/BD=AC/AE

The value of 2 in 2783 is 10 times the value of 2 in 7238

Place value of a number can be defined as the position of each digit in a number.

It is the value represented by a digit in a number on the basis of its position.

It is also known as system in which the position of a digit in a number determines its value.

Example:

The place value of 5 in 3500 is 500

The place value of 2 in 3240 is 200

Given the values:

2783 and 7283

The place value of 2 in 2783 is 2000

The place value of 2 in 7283 is 200

Find the quotient, we have:

= 2000/ 200

= 10

The value of 2 in 2783 is 10 times the value of 2 in 7238

The equation of the line passing through points (-3,0) and (0,3) is y=x+3.

The equation of the line passing through two points (x₁,y₁) and (x₂,y₂) can be calculated using the formula y-y₁=m(x-x₁)   ,  where m denotes the slope of the line .

from the given graph we can find that the line passes through the two points (-3,0) and (0,3)

we get the values , as x₁=-3 , x₂=0 and y₁=0 , y₂=3 .

Slope of the line can be calculated by using the formula ,

m=(y₂-y₁)/(x₂-x₁)

Substituting the values we get ,

m = (3-0)/(0+3)

m=3/3 = 1

Now substituting the values of x₁, x₂, y₁, y₂ and m in the formula of equation of line we get ,

y-0=1(x-(-3))

y-0=1(x+3)

y-0=x+3

y=x+3

Therefore , the equation of the line passing through points (-3,0) and (0,3) is y=x+3.

The equation of Amir's altitude relative to sea level (in meters) and time (in minutes) is: y=-12x+360.

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined on both sides of a point.

First of all let's write the slope-intercept form of the equation of a line, which is:

y=mx+b

where m is the slope and b is y intercept.

So we just need to find  m and b to solve this problem.

Moreover, this problem tells us that Amir drove from Jerusalem down to the lowest place on Earth, the Dead Sea, descending at a rate of 12 meters per minute. So this rate is the slope of the line, that is:

m=-12

Negative slope because Amir is descending. So:

y=-12x+b

To find b, we need to use the information that tells us that he was at sea level after 30 minutes of driving, so this can be written as the point (30,0
). Therefore, substituting this point into our equation:

y=-12x+b

0=12(30)+b

0=-360+b

b=360

Finally, the equation of Amir's altitude relative to sea level (in meters) and time (in minutes) is:

y=-12x+360.

Therefore  the equation of Amir's altitude relative to sea level (in meters) and time (in minutes) is: y=-12x+360.

Solution:

Let f(x) = (x+3)^(1/3).

First, we have

lim_(x → -3) f(x) = (-3+3)^(1/3) = 0 = f(-3)

So f(x) is continuous at a = -3.

Next we have

lim_(h → 0) [f(-3+h) - f(-3)] / h

= lim_(h → 0) h^(1/3) / h

= lim_(h → 0) 1 / h^(2/3)

= infty

Since the limit does not exist, f(x) is not differentiable at a = -3.

The area of the shaded region is equal to 425π / 18 square centimeters.

The picture indicates us that we must find the area of the shaded region, consisting in a circular section with a measure of central angle of 85° and a radius of 10 centimeters. The area (A), in square centimeters, can be found by using the following formula:

A = (α / 360) · π · r²

Where:

If we know that α = 85° and r = 10 cm, then the area of the shaded region is:

A = (85 / 360) · π · 10²

A = 425π / 18 cm²

The area of the shaded region is equal to 425π / 18 square centimeters.

5x² - 20x + k = 0

k = - 5x² + 20x

k = - 5(2)² + 20(2)

k = -20 + 40

k = 20

Answer + Step-by-step explanation:

Consider the equation :

5x² - 20x + k = 0

∆ = b² − 4bc is the discriminant of the quadratic equation.

In our equation :

a = 5  ;  b= -20  ;  c = k

Then

∆ = (-20)² − 4×5×k

   = 20² − 20k

   = 20×(20 − k)   (Factoring)

The equation 5x² - 20x + k = 0 has exactly one real solution

if and only if  ∆ = 0.

Solving the equation ∆ = 0 :

∆ = 0

⇔ 20×(20 − k) = 0

⇔ (20 − k) = 0    (Zero product property)

⇔ k = 20

Answer:

y = 4/3x - 5

Step-by-step explanation:

y-intercept will be (0,-5)

so m = (y2-y1)/(x2-x1)

m = (-5 -7)/(0 - 9) = (-12)/(-9) = 4/3

Using m = 4/3, y = 7, x = 9

y = mx + b

7 = 4/3(9) + b

7 = 12 + b

b = -5

so

y = 4/3x - 5

So, For this purpose, we know that the

Algebraic expression definition, a symbol or a combination of symbols used in algebra, containing one or more numbers, variables, and arithmetic operations

From the given information:

-5y^2 +50y - 105

Now to find the value of this

Rearrange the expression by taking the common values from this.

then

-5y^2 +50y - 105 = 0

-5y^2 +50y - 105 = 0

5(-y^2 +10y - 21) = 0

5(-y^2 +10y - 21) = 0

5(y^2 - 10y + 21) = 0

Now make factors of it then

5(y^2 - 7y - 3y + 21) = 0

5(y (y -7) -3(y-7)) = 0

5(y-3) (y-7) = 0

So, The value of the expression become 5(y-3) (y-7) = 0. Thus , The option C is correct.
