I Need To Use The Formula Value, A = P(1 + Rt), And Elementary Algebra To Find The Principal

Answers

Answer 1

P= $1300

Explanation

when you have the rate, the time and the initial value , you can find the principial by using the formula

[tex]\begin{gathered} A=P(1+rt)^ \\ where\text{ P is the principal} \\ A\text{ is the amounnt} \\ r\text{ is the rate \lparen in decimal\rparen} \\ t\text{ is the number of periods} \end{gathered}[/tex]

so

Step 1

a)let

[tex]\begin{gathered} A=1508 \\ r=4\text{ \%=}\frac{4}{100}=0.04 \\ t=4\text{ \lparen years\rparen} \end{gathered}[/tex]

now, replace in the formula

[tex]\begin{gathered} A=P(1+r)^ \\ 1508=P(1+0.04*4) \\ 1508=P(1.16) \\ divide\text{ both sides by 1.16} \\ \frac{1,508}{1.16}=\frac{P(1.16)}{1.16} \\ 1300=P \end{gathered}[/tex]

therefore, the answer is

P= $1300

I hope this helps you

You need to lay tile to create a frieze above a Forrest . The title measure 2 7/8 in by 2 7/8 if the doorway is 36 1/2 inches wide how many piece of tile you need

Answers

After solving basic fractions we have come to find that, we need 12.7 tiles to create a frieze above a Forrest.

What is fraction?

When describing a portion or part of a whole in mathematics, a fraction is used. The equal components of the whole are represented by it. Both the numerator and denominator are components of a fraction.

Both the top and bottom numbers are referred to as the numerator and denominator, respectively. The denominator specifies the total number of equally sized pieces in the whole, whereas the numerator specifies the number of equal parts that were taken.

A fraction is something like 5/10.

The denominator in this case is 10, and the numerator is 5.

The measure of each tile = 2⅞

                                          = 23/8

Measure of doorway = 36½

                                   =  73/2

No. of tiles we need = 36½ /  2⅞

                                  = 12.7 tiles

Thus, we need 12.7 tiles to create a frieze above a Forrest.

MATRECIES: Suppose ={u,v,w}⊆R3 is linearly independent. Determine if the set 4 ={u, v, v−w, u+v+w} is linearly independent or linearly dependent.

Answers

The set is linearly dependent.

To explicitly prove this, we need to show there is at least one choice of constants [tex]c_1,c_2,c_3,c_3\in\Bbb R[/tex] such that

[tex]c_1 u + c_2 v + c_3(v-w) + c_4(u+v+w) = 0[/tex]

or equivalently,

[tex](c_1 + c_4) u + (c_2 + c_3 + c_4) v + (-c_3 + c_4) w = 0[/tex]

which is the same as solving the system of equations

[tex]\begin{cases} c_1 + c_4 = 0 \\ c_2 + c_3 + c_4 = 0 \\ -c_3 + c_4 = 0 \end{cases}[/tex]

From the first and last equations, we have [tex]c_1=-c_4[/tex] and [tex]c_3=c_4[/tex]. Substituting these into the second equation leaves us with [tex]c_2-2c_1=0[/tex], and so the overall solution set is

[tex]c_1 = \dfrac12 c_2 = -c_3 = -c_4[/tex]

for which there are infinitely many not-all-zero solutions.

Hello! Need some help on parts a,b, &c. The question and rubric is linked below. Thank you!

Answers

Answer:

Part A: -5/9, 6/10, -7/11, 8/12

Part B:

[tex]f(n)=(-1)^{n}(\frac{n}{n+4})[/tex]

Part C: Positive

Explanation:

The given sequence is:

[tex]-\frac{1}{5},\frac{2}{6},-\frac{3}{7},\frac{4}{8},....[/tex]

As seen above the sequence is an alternating sequence because it changes in sign

Also, neglecting the sign chnages, we will observe, a common diffference of 1 in the numerator and denominator

a) Therefore, if the pattern continues, the next 4 terms in the sequence are:

-5/9, 6/10, -7/11, 8/12

b)

Without the sign, the explicit equation representing the numerator is calculated below:

1, 2, 3, 4......

The first term, a = 1

The common difference, d = 1

This is an arithmetic sequence

N(n) = a + (n - 1)d

N(n) = 1 + (n - 1)(1)

N(n) = 1 + n - 1

N(n) = n

The explicit equation representing the denominator is calculated below

5, 6, 7, 8........

The first term, a = 5

The common difference, d = 1

D(n) = a + (n - 1)d

D(n) = 5 + (n - 1)(1)

D(n) = 5 + n - 1

D(n) = n + 4

The alternating sequence will include the term below:

[tex](-1)^n[/tex]

Therefore, the explicit equation for f(n) representing the sequence is:

[tex]f(n)=(-1)^n(\frac{n}{n+4})[/tex]

Part C) The sign of f(56) will be:

(-1)^56 = 1

Since this gives us a positive value, the sign of f(56) is positive

Answers

The true statement is g(-13)= 20.

What is domain and range?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. Mapping or transformation is used to denote a function in math. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

domain = -20 ≤ x ≤ 5

and a range = -5 ≤ g(x) ≤ 45

and g(0) = -2 and g(-9) = 6

First, g(-13)= 20

x=-13 is in our domain  and 20 is also in our range .

So this is true for g(-13)= 20.

Now, g(-4) = -11

-11 does not comes under the range.

So this statement is not true.

Again,  g(0) = 2 is false because  g(0) = - 2.

and,  g(7) = -1 D

7 is not in our domain .

So g(7) is not possible

Answers

D. 763 seconds

Explanation:

Data:

Seconds light travels distance between Sun and Earth : 500 seconds

Distance between Sun and Earth: 93 million miles

Distance between Sun and Mars: 142 million miles

Formula: (see image below)

Solution:

From Sun to Mars the light takes (142 * 500) / 93 = 763 seconds

NB:

The tactic is to first put the data given in a table like in the image above, to first multiply diagonally then divide horizontally. (starting from the data that his paired data).

Here the paired data missing is the time it takes for the light to travel from the Sun to Mars, therefore you'll multiply the distance between the Sun to Mars (known data missing a pair) by the time it takes light to travel from the Sun to Earth (known data with its pair), then divide the result by the distance between the Sun and earth (pair of the former mentioned known data)

On a recent ride, 28% of Lance's ride was uphill, 33% was downhill and the rest of the ride was on a mostly flat surface. If the distance he covers is 475 km, how long do you think he took to complete his ride? Show your work.​

Answers

Answer:

10.59480821 hours

Step-by-step explanation:

First, we need to know the percent of the flat surface. so we are gonna add the uphill and down hill then take the sum and find the difference from 100%

28+33+x=10061+x=100[tex]\frac{61+x}{-61} =\frac{100}{-61}[/tex]x=39

2. Now we know the percent for each surface

Uphill = 28%Downhill = 33%Flat = 39%

3. Now that we know the percent of each surface we need to find out how many km for each surface:

Uphill

0.28×475=133km

Downhill

0.33×475=153.75km

Flat

0.39×475=185.25km

3. Now that we know all the percent and distance for each surface we need to know the km/h for each

Uphill = 24.25km/h

Downhill = x

Flat = 55.5km/h

4. Since we don't have the speed for downhill we need to know the difference between uphill and flat

55.5-24.25=31.25

5. Now we know the difference is 31.25 we can add that to the flat surface to get the downhill speed

55.5+31.25=86.75Downhill =86.75km

6. Now we know all the speeds and now we can figure out how many hours it takes for each surface

( we are going to take the distance in 1 surface and then divide that by the km/h in that surface to ket how many hours)

Uphill

133÷24.25=5.484536082 hours

Downhill

153.75÷86.75=1.772334294 hours

Flat

185.25÷55.5=3.337837838 hours

7. Now we add all the hours up

The image of the point P(x, y) = (4, 2) by means of a translation formula is point P'(x, y) = (- 1, 4).

What is the image of a given point after making a translation?

In this question we find the coordinates of a point set on Cartesian plane which is modified by using a translation, a kind of rigid transformation. Rigid transformations are transformations applied on geometric loci such that Euclidean distances are conserved.

Vectorially speaking, translations are described by the following formula:

P'(x, y) = P(x, y) + T(x, y)

Where:

P(x, y) - Original pointP'(x, y) - Resulting pointT(x, y) - Translation vector

If we know that P(x, y) = (- 9, - 3) and P'(x, y) = (- 14, - 1), then the translation vector is:

T(x, y) = P'(x, y) - P(x, y)

T(x, y) = (- 14, - 1) - (- 9, - 3)

T(x, y) = (- 5, 2)

Then, the image of the point (4, 2) is:

P'(x, y) = (4, 2) + (- 5, 2)

P'(x, y) = (- 1, 4)

The image of the point (4, 2) by using a translation formula is (- 1, 4).
