Answer:

9090

Step-by-step explanation:

Answer:

I = $ 90.90

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 4.5%/100 = 0.045 per year,

then, solving our equation

I = 505 × 0.045 × 4 = 90.9

I = $ 90.90

The simple interest accumulated

on a principal of $ 505.00

at a rate of 4.5% per year

for 4 years is $ 90.90.

Answer:

(x, y) = (1, 1)

Step-by-step explanation:

[tex] -27x + 6y = -21 [/tex] --- (1)

[tex] -12x +3y = -9 [/tex] --- (2)

Multiplying (2) by -2 to get:

[tex] 24 x - 6 y = 1 8 [/tex] --- (3)

Adding (1) and (3) to get:

[tex]-27x + 6y = -21[/tex]

[tex]24x-6y=18[/tex]

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

[tex]-3x=-3[/tex]

x = 1

Finding y:

[tex]-12(1) +3y = -9[/tex]

[tex]3y=-9+12[/tex]

[tex]3y=3[/tex]

y = 1

Therefore, (x, y) = (1, 1).

(X,Y)= (1,1)

Explanation:

Answer:

Step-by-step explanation:

first solve for x

x-16=8

add 16 to both sides to isolate x, you now have:

x=8+16

x=24

soooo...now you have to plug in x into the other equation.

3(x+7) turns into 3(24+7)

so now we solve.

3(24+7)

3 x 31

93=x

Hope this was helpful!

The value of x in the equation x-16=8 is found to be 24. Substituting x into the expression 3(x+7) yields a final result of 93.

The equation given in this question is: x-16=8. To find the value of x, add 16 to both sides of the equation. So, x = 8 + 16, which simplifies to x = 24.

Next, to find the value of 3(x+7), you first replace the x with the value we have just found. That gives you 3(24 + 7) which equals 3(31). Multiplying this out gives the final answer, 3(31) = 93.

Three methods to solve the equation are Division as Repeated Subtraction,Using Fraction Division Formula,Using Decimal Conversion.

I'll approach this problem using three different methods:

Method 1: Division as Repeated Subtraction

Dividing [tex]\( \frac{1}{3} \)[/tex] by 5 means finding out how many times 5 can be subtracted from 1/3

[tex]\( \frac{1}{3} - 5 = - \frac{14}{3} \)[/tex]

So, you can subtract 5 from 1/3 approximately 0 times with a remainder of [tex]\( - \frac{14}{3} \).[/tex]

Method 2: Using Fraction Division Formula

To divide a fraction by a number, you can multiply the fraction by the reciprocal of the number.

[tex]\( \frac{1}{3} \div 5 = \frac{1}{3} \times \frac{1}{5} \)[/tex]

[tex]\( \frac{1}{3} \times \frac{1}{5} = \frac{1 \times 1}{3 \times 5} \)[/tex]

[tex]\( \frac{1}{3} \div 5 = \frac{1}{15} \)[/tex]

So, [tex]\( \frac{1}{3} \div 5 = \frac{1}{15} \).[/tex]

Method 3: Using Decimal Conversion

Converting 1/3 to a decimal gives [tex]\( 0.3333... \)[/tex]

Then, dividing 0.333 by 5 gives:

[tex]\( 0.3333... \div 5 \approx 0.0667 \)[/tex]

So, [tex]\( \frac{1}{3} \div 5 \approx 0.0667 \).[/tex]

These are three different ways to solve the problem [tex]\( \frac{1}{3} \div 5 \).[/tex]

Answer:

Step-by-step explanation:

1.  Replace F(x) with y.

2.  Interchange x and y in  y = 2x + 1:  x = 2y + 1

3.  Solve this result for y:  2y = x - 1, or y = (x - 1)/2

4.  Replace y with:

   -1

F     (x):

   -1             x - 1

F     (x) = -----------

Answer:

f-1(x) = (x - 1)/2.

Step-by-step explanation:

Let f(x) = y

y = 2x + 1

2x = y - 1

x = (y - 1)/2

Now replace x by the inverse of f(x) ( that is f-1(x) ) and y by x:

f-1(x) = (x - 1)/2.

Answer:

solutions to f(x)=g(x) are x=-1 and x=8

Step-by-step explanation:

The minimum point of the parabola will be found at ...

x = -b/(2a) . . . . . where a, b, c are the coefficients of ax²+bx+c

For g(x) = x² -6x -7, the minimum will be at x=-(-6)/(2·1) = 3. The minimum value is ...

g(3) = 3² -6·3 -7 = -16

so the vertex (minimum point) you want to plot is (3, -16). Since the coefficient of x² is 1, there is no vertical scaling, so when the value of x differs from 3 by 1 unit, the value of g(x) will be 1² = 1 unit higher. That is, g(4) = -15, so (4, -15) is another point on the parabola.

Answer:

The possible lengths of the third side is all real numbers greater than 4 inches and less than 20 inches

Step-by-step explanation:

we know that

The Triangle Inequality Theorem. states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

Let

x -----> the possible lengths of the third side

Applying the Inequality Theorem

1) 12+8 > x

20 > x

Rewrite

x < 20 in

2) 8+x > 12

x> 12-8

x > 4 in

therefore

4 in < x < 20 in

The possible lengths of the third side is all real numbers greater than 4 inches and less than 20 inches

Answer:

Variance σ² having standard deviation 2.5 is 6.25.

Step-by-step explanation:

The standard deviation is basically the square root of the variance.

So, if want to find the variance of the data we simply take square of standard deviation to get the variance of data.

standard deviation = σ = 2.5

taking square on both sides

(σ)² = (2.5)²

σ² = 6.25

So, variance σ² having standard deviation 2.5 is 6.25.

Step-by-step explanation:

given y = f(x), then

y = f(x) + c is a vertical translation

• If c > 0 then vertical shift up of a units

• If c < 0 then vertical shift down of a units

here c = - 2, hence shift down of f(x) by 2 units

[tex]\large\boxed{h>2\ \vee\ h<1\to h\in(-\infty,\ 1)\ \cup\ (2,\ \infty)}[/tex]

Step-by-step explanation:

[tex]|2h-3|>1\iff2h-3>1\ \vee\ 2h-3<-1\qquad\text{add 3 to both sides}\\\\2h>4\ \vee\ 2h<2\qquad\text{divide both sides by 2}\\\\h>2\ \vee\ h<1\to h\in(-\infty,\ 1)\ \cup\ (2,\ \infty)[/tex]

The solution of the absolute value inequality |2h-3| > 1 is h > 2 or h < 1. Two cases are considered based on whether the expression inside the absolute value is greater than 1 or less than -1.

To solve the inequality |2h-3| > 1, you need to consider two cases because an absolute value inequality represents two separate inequalities.

Case 1: The expression inside the absolute value (2h-3) is greater than 1. This gives us the inequality 2h - 3 > 1. Solving for h, we get h > 2.

Case 2: The expression inside the absolute value (2h-3) is less than -1. This gives us the inequality 2h - 3 < -1. Solving for h, we get h < 1.

Thus, the solution of the absolute value inequality is h > 2 or h < 1.

x= -7 , y= 9

Steps:

4x+3y=-1

5x+4y=1

First, multiply the top equations by -5, and the bottom by 4 to get :

-20x-15y=5

20x+16y=4

Then, you’re going to add the two equations with them being on top of each other so you can easily see what cancels out :

-20x-15y=5

+ 20x+16y=4

———————

0+1y=9

From this, you get :

y=9

Now that you have one variable, find x by substituting 9 for y in one of the equations, I choose :

4x+3y=-1

So :

4x+3(9)=-1

Then simplify by multiplying 3 and 9 :

4x+27=-1

Then subtract 27 on each side :

4x=-28

Then, divide by 4 to get that :

pi= 3.14

r= 49^2=

49 X49= 2,401

2,402 X 3,14= 7,539.14

Answer:

A = 7539.14 mm^2

Step-by-step explanation:

Area of a circle is given by

A = pi * r^2

We need to know the radius

r = d/2

r = 98/2

r = 49 mm

The radius is 49 mm and pi = 3.14

A = 3.14 * (49)^2

A = 7539.14 mm^2

Answer:

21 articles of clothing are clean.

Step-by-step explanation:

If 2/5 clothes, or 40% of them, are dirty, then 3/5, or 60% of them are clean.

Multiply 35 by 0.60, and you get your answer.

35 x 0.60 = 21.

We can check this answer by multiplying 0.40 by 35 to get the amount of dirty clothes and adding that amount to 21, which should equal 35.

35 x 0.40 = 14

14 + 21 = 35

To find out how many articles of clothing were clean, we set up a ratio equation using the given ratio of 2 to 5. By representing the number of clean clothes with a variable and using the total count of 35 clothes, we determined that Meredith found 10 clean articles of clothing.

When Meredith cleaned her room, she found that the ratio of clean clothes to dirty clothes was 2 to 5. If there were 35 articles of clothing in total, the problem can be approached by assigning a variable to represent the number of clean clothes. Let's denote the number of clean clothes by c and the number of dirty clothes by d.

Based on the given ratio, we can write the equation as 2/5 = c/d. Since we know that c + d = 35, we can use these two equations to solve for c.

We express d in terms of c as d = 35 - c.

Substituting this into the ratio equation, we get 2/5 = c/(35 - c). Cross multiplying gives us 5c = 2(35 - c), which simplifies to 5c = 70 - 2c.

Solving for c, we add 2c to both sides to get 7c = 70. Dividing both sides by 7 gives us c = 10. Therefore, Meredith found 10 clean articles of clothing.

Answer:

Option B: [tex]y=log_2(x-3)[/tex]

Step-by-step explanation:

To obtain the inverse of the function [tex]y= 2^x + 3[/tex], you need to solve the equation for the variable "x":

[tex]y= 2^x + 3\\\\y-3=2^x\\\\log_2(y-3)=log_2(2^x)\\\\x=log_2(y-3)[/tex]

Now you need to exchange the variable "x" with the variable "y". Then:

[tex]y=log_2(x-3)[/tex]

Finally, you get that the inverse of the function [tex]y= 2^x + 3[/tex] is:

[tex]y=log_2(x-3)[/tex]

This matches with the option B.

Answer:

B. line segment

because without the point A it would be a ray

or without the arrow after point a it would be a line

The figure a(n) represents a line segment Option(B)

A line is a one-dimensional figure, which has length but no width. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane.

In geometry, a ray is usually taken as a half-infinite line (also known as a half-line) with one of the two points and. taken to be at infinity.

A line segment is bounded by two distinct points on a line. A line has no endpoints and extends infinitely in both the direction but a line segment has two fixed or definite endpoints.

The given figure is a line segment as it has two end points a and b and also it is bounded by the similar two extended point .

Therefore a(n) is a line segment, Option (B.)

Answer:

C, (x - 4)(x - 2)

Step-by-step explanation:

to factor x² - 6x + 8, you need to find 2 numbers that multiplied together are equal to 8 and added together that are equal to -6

we can already eliminate answers B and D, since B added together does not equal -6, and D multiplied together does not equal 8

we are left with choices A and C

in order to get a positive 8 through multiplication, we need either two positive numbers, or two negative numbers

to get a -6 through addition, we need negative numbers

lets test (x - 4)(x- 2) to see if this works in the equation, we can use FOIL to expand the equation and we get:

x² -4x - 2x + 8

x² -6x + 8

our answer would be C, (x-4)(x-2)

The factored form of x^2 - 6x + 8 is (x - 2)(x - 4), which is option c.

To factor the expression x^2-6x+8 into its factored form, we are looking for two binomials (x - a)(x - b) such that when multiplied out, the result will be our original quadratic expression. The factors need to multiply to give the constant term 8, and add up to give the middle term -6. Starting with the constant term, the pairs of factors of 8 are (1, 8), (2, 4), and (-2, -4). We need to find the pair that adds up to -6, which is (-2, -4).

So, the factored form of x^2-6x+8 is (x - 2)(x - 4), and the correct choice here is option c.) (x - 4)(x - 2).
