What is the Factored Form of 7d^6 + 8g^12

Answer:

$25,900 initially

$8,128 after 11 years

Step-by-step explanation:

One thing to note, is I'm assuming you meant: [tex]v(t)=25,900(0.90)^t[/tex] and not  [tex]v(t)=25,900(0.90)^2[/tex], otherwise that would just be a constant function and not an exponential function.

There are a couple key features of exponential functions we can derive from simply analyzing the equation.

For now I will be using the form: [tex]y=a(b)^x\text{ where b} > 0, \text{b}\ne 1[/tex]

The y-intercept, is just the "a" value, which is because the y-intercept is simply when x=0, and if we raise a number to the power of zero, we get one (excluding zero as a base), so we get the form: [tex]y=a[/tex], so "a" is our y-intercept.

there's actually two type of exponential functions: exponential growth and exponential decay.

Exponential Decay:

Exponential decay, as the name implies, is when a function is decaying or decreasing. This occurs when [tex]0 < b < 1[/tex].

The decay rate can be represented as "r" in decimal form, where: [tex]b=1-r[/tex].

The reason for this is because "1" can be thought of as 100% and "r" is r%, so you're taking away r% or decaying the value by r%, also known as a decay rate.

Exponential Growth:

Exponential growth as the name implies, is when a function is growing or increasing. This occurs when b > 1

The growth rate can be represented as "r" in decimal form where: [tex]b=1+r[/tex]

The reason for this is similar to decay rate except instead of taking away r% or decaying, it's "giving r%" or growing.

The question doesn't actually require finding exponential growth or decay, but it's still an important key feature.

In this case, we really just need to find the y-intercept and plug in t=11.

The y-intercept in many graphs, not just exponential graphs, represents some sort of initial value, which in this case, is the initial value of the car. As stated above, this y-intercept is just the value in front, which is 25,900.

As for the value after 11 years, we simply need to plug in t=11 to get the following: [tex]v(11)=25,900(0.90)^{11}[/tex], from here we can use a calculator to simplify this: [tex]v(11)\approx25,900(0.31381059609)\approx 8,127.694438731[/tex], which rounds to 8,128

Answer: If 2 melons cost Php190.50, then 4 melons cost 381 .

If 1 kg of Bangus costs Php167.35, then 3.5 kgs of Bangus cost 585.725

Step-by-step explanation:

2x2=4

1x3.5=3.5

167.35x3.5=585.725

The ratio of the amount Peter spent to that of John is 2:3, so:

(a) If Peter spent 500 dollars, then John spent 75p dollars

(b) If John spent 600 dollars, then they spend altogether 1000 dollars.

(c) If both boys spent 2000 dollars altogether, then John spent 1200 dollars and Peter spent 800 dollars.

(d) If John spent 100 dollars more than Peter, then they both spent 500 dollars as Peter will spend 200 dollars while John spends 300 dollars.

Let us represent the amount of money spent for Peter and John with P and J respectively.

Using the ratio 2:3 for the amount Peter spent to that of John;

If Peter spent 500 dollars, then;

2/3 = $500/J {cross multiply}

J = (3 × $500)/2

J = $1500/2

J = $750

If John spent 600 dollars, then;

2/3 = P/$600 {cross multiply}

P = (2 × $600)/3

P = $1200/3

P = $ 400

Peter and John spent altogether = $1000

If both boys spent 2000 dollars altogether, then;

their total ratio = 5

unit amount = $2000/5

unit amount = $400

Peter spent = 2 × $400 = $800

John spent = 3 × $400 = $1200

If John spent 100 dollars more than Peter, then;

2/3 = P/(P + $100) {cross multiply}

3P = 2(P + $100)

3P = 2P + $200 {collect like terms}

3P - 2P = $200

P = $200.

Peter spent = $200

John spent = $300.

In conclusion, using the ratio 2:3 for the amount of money spent by Peter and John respectively, we have the answers: $750, $1000, $800 for Peter and $1200 for John, and $200 for Peter and $300 for John for the questions lettered (a), (b), (c), and (d) respectively.

The statement that "the midpoint of a line is found by subtracting two coordinates and dividing the answers by two" is false

The midpoint of a line segment is the centroid of the segment. It is equally distant from both of the ends and hence cuts the section in half.

The formula to determine the center point of a straight line using the coordinates of its endpoints is known as the midpoint formula in coordinate geometry.

The formula is of the form

X= (x₂ + x₁)/2

Y = (y₂ + y₁)/2

From the formula midpoint involves addition two coordinates instead of subtraction, and dividing by two.

Answer: D

Step-by-step explanation:

First, we need to find the number of students that are freshmen: 3400 students x 3/8 = 1050 students

Next, we need to find the number of students that are in favor of forming a track team: 3/5 of the freshmen are in favor = 3/5 * 1050 = 630 students

To find the number of non-freshmen students: 3400 students - 1050 students = 2350 students

Now we need to find the number of non-freshmen students in favor of forming a track team: 1/5 of the non-freshmen students are in favor = 1/5 * 2350 = 470 students

Finally, to find the number of students opposed to the idea we need to subtract the number of students in favor from the total number of students: 3400 students - (630 students + 470 students) = 3400 - 1100 = 2300 students

So there are 2300 students at Central High School that are opposed to the idea of forming a track team.

Answer:

1440

Step-by-step explanation:

"Percent" means "out of 100"

5 "percent" means 5 out of 100

[tex]\frac{5}{100} =\frac{72}{x}[/tex]

We need to find the number that when multiplied by 5, equals 72.

72 / 5 = 14.4

Now, we need to multiply 100 by 14.4 to "scale" proportionately.

100 * 14.4 = 1440

We can check our work:

1440 * (0.05) = 72

The equation 1/2r = π/CB is true. Choose the second option

The circumference of a circle is the distance around the circle, or the length of the perimeter of the circle. It is given by the formula:

circumference = 2πr = πd

where r is the radius and d is the diameter

Note: d = 2r

Given: d2 = 2r and CB denotes the circumference of ⨀B

CB =  πd2  

CB =  2πr   (d2 = 2r)

Divide both sides by CB:

CB/CB =  2πr/CB

Answer:

The average rate of change is −10.

Step-by-step explanation:

The average rate of change of f(x) on the interval [a,b] is f(b) − f(a) / b−a.

We have, a=3, b=5, f(x) = -1x^2 − 2x + 2.

Thus, f(b) − f(a) = −(5)^2 −2(5) + 2 − [−(3)^2 −2(3) + 2]

= -25 - 10 + 2 - ( -9 - 6 + 2 )

= -33 - 13

= - 20

Then, b−a = 5 - 3 = 2

f(b) − f(a) / b−a = - 20 / 2 = −10

Answer: the average rate of change is −10.

The measure of ∠A is 123 degrees.

The angle made between the radius and the tangent at the point of contact on a circle is 90°.  

Therefore,

∠D = 90 degrees

∠E = 90 degrees

The diagram ACDE forms a quadrilateral. The sum of angles in a quadrilateral is 360 degrees.  Therefore, we have to equate the sum of the quadrilateral angles to 360 degrees.

Hence,

90 + 90 + 2x + 7 + 5x - 2 = 360

180 + 7x + 5 = 360

7x = 360 - 180 - 5

7x = 180 - 5

7x = 175
