Answer:
[tex]2 * 10^3 * 1,02^t[/tex]
Step-by-step explanation:
Let [tex]S = 2000 = 2 * 10^3[/tex] dollars be our investment, [tex]r = 2\%[/tex] - our interest rate. In order to simplify things, I suggest bringing the variable [tex]p[/tex] into play: [tex]p = 1 + \frac{r}{100}[/tex]. So, after year [tex]1[/tex] we will have [tex]S_{1} = S + \frac{r}{100}S = S(1 + \frac{r}{100} ) = Sp[/tex]. After year [tex]2[/tex]: [tex]S_{2} = S_{1}p = Sp * p = Sp^2[/tex]. After year [tex]t[/tex]: [tex]S_{t} = S_{t - 1}p = Sp^t[/tex]. Besides, we can count [tex]p[/tex]. Indeed, [tex]p = 1 + \frac{r}{100} = 1 + \frac{2}{100} = \frac{100}{100} + \frac{2}{100} = \frac{102}{100} = 1,02[/tex]. Therefore, [tex]V(t) = Sp^t = 2 * 10^3 * 1,02^t[/tex].
To join a new fitness center, there is a $40 initiation fee. It costs an additional $10 for every spinning class you attend. What is the average cost per class if you take 10 classes in the first month of joining the fitness center
the average cost per class is $14.
Think of this as an algebraic equation, which would be expressed as 40+10s=total cost
The (s) would be the number of spinning classes you decide to take.
Therefore to find the average cost of the class, you would plug in 10 classes for s.
This brings the total cost to $140 dollars.
To find the average you must divide this cost by the number of classes you took.
This will be the price per class, which is $14.

First, we multiply the numbers : 10 x 5 = 50
Now, we multiply r squared to r^6. To do this, we add the index numbers together : r^2 x r^6 = r^(2+6) = r^8
So, the answer is 50r^8, or b.

Answer:
14
Step-by-step explanation:
when two lines intersect, the opposite angles are equal: vertical angles rule
this means that 88 and 6x + 4 are the same, therefore we get the equation 6x+4 = 88.
subtracting 4 from both sides, we find that 6x = 84
we get our final answer by dividing each side of the equation by 6:
x = 14
An arithmetic sequence has this recursive formula:
a1= 5
an= an-1-4
The explicit formula for the sequence is an = 5 + (n - 1)(-4)
Explicit rule of a sequenceThe formula for calculating the nth term of an arithmetic sequence is expressed as:
an = a + (n - 1)d
where
a is the first term
d is the common difference
n is the number of terms
From the given data
a = 5
a2 = a1 - 4
a2 = 5 - 4
a2. = 1
d = a2 - a
d = 1 - 5
d = -4
Substitute
an = 5 + (n - 1)(-4)
Hence the explicit formula for the sequence is an = 5 + (n - 1)(-4)

A distance travaled by train in three hours with a constant speed of r miles per hour
The distance travelled by the train with constant speed of r miles will be 3r.
What is Speed?The most crucial scientific notion is measurement. Base or physical fundamental units are used to quantify a wide range of quantifiable quantities. One such measurable metric is speed, which calculates the ratio between the distance an object travels and the time needed to cover that distance. Let's explore speed in-depth in this session. The pace at which an object's location changes in any direction. When an object travels the same distance in the same amount of time, it is said to be moving at a uniform speed. When an object travels a different distance at regular intervals, it is said to have variable speed.We know the formula of distance linking the speed and the time.
Distance = speed × time
Substituting the given values to get:
Distance = r × 3
Distance = 3r

Which equation represents the line that is perpendicular to and passes through (-40,20)?
The equation of the perpendicular line to the given line is: y = -5/4x - 30.
What is the Equation of Perpendicular Lines?The slope values of two perpendicular lines are negative reciprocal of each other.
Given that the line is perpendicular to y = 4/5x+23, the slope of y = 4/5x+23 is 4/5. Negative reciprocal of 4/5 is -5/4.
Therefore, the line that is perpendicular to it would have a slope (m) of -5/4.
Plug in m = -5/4 and (x, y) = (-40, 20) into y = mx + b to find b:
20 = -5/4(-40) + b
20 = 50 + b
20 - 50 = b
b = -30
Substitute m = -5/4 and b = -30 into y = mx + b:
y = -5/4x - 30
The equation of the perpendicular line is: y = -5/4x - 30.

Step-by-step explanation:
1. multiply by 8
2. divide by 2
Answer:
4096, 125
Step-by-step explanation:
In the first sequence, notice that each term increases by a factor of 8 (multiplied by 8 each time). Therefore, the fourth term would be 64*8 = 512, so the fifth term is 512*8 = 4096.
In the second sequence, each term decreases by a factor of 2 (divided by 2 each time). The fourth term would be 500/2 = 250, so the fifth term is 250/2 = 125.

Using the given linear function of best-fit, the most likely approximate height of the plant after 8 weeks would be of 7.4 centimeters.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.The line of best-fit goes through points (0,1) and (5,5). Point (0,1) means that the y-intercept is of b = 1. The slope is given as follows:
m = (5 - 1)/(5 - 0) = 4/5 = 0.8.
Hence the equation that gives the approximate height after x weeks is:
y = 0.8x + 1.
After 8 weeks, the expected height is:
y = 0.8 x 8 + 1 = 6.4 + 1 = 7.4 centimeters.

Find two numbers such that one number is 3 less than twice as big as the other number and the two numbers sum to 21.
Answer:
The two numbers are:
8 and 13
Step-by-step explanation:
a = 2b - 3 Eq. 1
a + b = 21 Eq. 2
Replacing Eq. 1 in Eq. 2:
(2b-3) + b = 21
3b - 3 = 21
3b = 21 + 3
3b = 24
b = 24/3
b = 8
from Eq. 1
a = 2*8 - 3
a = 16 - 3
a = 13
Check:
From Eq. 2:
a + b = 21
13 + 8 = 21

A pillar 80 m tall casts a shadow 39 m long. Find the distance between the top of the pillar and the foot of the shadow
Answer:
89
Step-by-step explanation:
[tex] \sqrt{ {80}^{2} + {39}^{2} } = 89[/tex]
The distance between the top of the pillar and the foot of the shadow is 80 meters.
How to find the distanceLet's call the distance we want to find "x".
In particular, set up the following proportion:
pillar height / shadow length = distance / shadow length
Plugin the given values
80 / 39 = x / 39
Simplifying and solving for x
x = (80 / 39) * 39
x ≈ 80
