Answer:

[tex]3[/tex]

Step-by-step explanation:

This problem asks one to find the length of the given line. Another way to think about this problem is to believe that the problem asks one to find the distance from one point to another. The endpoints on this line are the following,

[tex](4,2), (5, 5)[/tex]

The formula to find the distance between two points on a 2-dimensional coordinate plane is as follows,

[tex]D=\sqrt{(x_1-x_2)^2*(y_1-y_2)^2}[/tex]

Substitute the endpoints of the line into the formula and solve for the distance between the points,

[tex]D=\sqrt{(4-5)^2*(2-5)^2}[/tex]

Simplify, solve for the distance between the two points,

[tex]D=\sqrt{(4-5)^2*(2-5)^2}[/tex]

[tex]D=\sqrt{(-1)^2*(-3)^2}\\\\D=\sqrt{1*9}\\\\D=\sqrt{9}\\\\D=3[/tex]

Answer:

d. 4

Step-by-step explanation:

The degree of freedom is the amount of independent data set used to calculate an estimate. The degree of freedom is quite different from the sample size (n). It is calculated by subtracting one(1) from the total value of the data set (sample size (n)).

From the information given:

The sample size is the number of people in the same group

sample size n = 5

degree of freedom = n - 1

= 5 - 1

= 4

Step-by-step explanation:

I'm assuming you meant to type in

[tex]f(x)=\frac{x^2+12x+27}{x^2+4x+3}[/tex] because you can only have removable discontinuities where there is a rational (fraction) function. Begin by factoring both the numerator and denominator to

[tex]f(x)=\frac{(x+3)(x+9)}{(x+1)(x+3)}[/tex] and cancelling out like terms would have us eliminating the (x + 3). That is where there is a removable discontinuity. It leaves a hole. The other discontinuity, (x + 1) doesn't cancel out so it is a non-removable discontuinity, which is a vertical asymptote.

The removable discontinuity is at -3. There is no y value at x = -3 (remember there's only a hole here), because -3 causes the denominator to go to 0 and we all know that having a 0 in the denominator of a fraction is a big no-no!!!

Answer:

3/2

Answer:

She missed her goal, because she made less than $75 on coffee today.

10

Step-by-step explanation:

Target profit = $75

Profit per cup = $0.80

Number of cups sold = 90

Profit made today = Profit per cup * Number of cups sold

= $0.80 * 90

= $72

She missed her goal, because she made less than $75 on coffee today.

2. (9.5 minus 3 times 1 and one-half) divided by 0.5

(9.5 - 3 * 1 1/2) ÷ 0.5

= 9.5 - 3 * 3/2 ÷ 0.5

= 9.5 - 9/2 ÷ 0.5

= (9.5 - 4.5) ÷ 0.5

= 5 ÷ 0.5

= 10

Answer:

  2. The x-intercept is 4, and the y-intercept is -3

Step-by-step explanation:

The given equation is in general form. I find it easier to see the intercepts when the equation is written in standard form:

  3x -4y = 12

Setting y=0 and solving for x, we have the x-intercept:

  3x = 12   ⇒   x = 12/3 = 4

Setting x=0 and solving for y, we have the y-intercept:

  -4y = 12   ⇒   y = 12/-4 = -3

The x-intercept is 4; the y-intercept is -3.

Answer:

-1 =s

Step-by-step explanation:

7 = -10s - 3

Add 3 to each side

7+3 = -10s - 3+3

10 = -10s

Divide by -10

10/-10 = -10s/-10

-1 =s

Answer:

p(m) = 0.1(m)

Step-by-step explanation:

Given that :

Percentage of cost saved per month = 10%

The percentage, p of cost saved after m months will be ;

Percentage of cost saved after m, months will be ; p(m) = Percentage of cost saved per month * number of months

p(m) = 10% * m

p(m) = 0.1(m)

Answer: The equation has 2 positive integer solutions:

x1 = 0   y1 = 2  

x2 = 1   y2 = 0  

Step-by-step explanation:

The value of x = -4.334  and y = 10.667.

When written as ax + by + c=0, where a, b, and c are real numbers and the coefficients of x and y, i.e., a and b, respectively, are not zero, an equation is said to be a linear equation in two variables.

For this kind of equation, the solution is a pair of values, one for x and one for y, which also make the two sides equal.

Given Equations 12x + 6y = 12...….(1)

    y  = x + 15

y - x = 15...….(2)

divide eq. (1) by 6

(12x + 6y)/6 = 12/6

2x + y = 2

subtract from eq. (2)

y - x  - (2x + y)  = 15 - 2

-3x = 13

x = -13/3 = -4.334

substitute value of x in eq. (2)

y - (-4.334) = 15

y = 15 - 4.334

y = 10.667

Hence the solution of equations gives x = -4.334 and y = 10.667.

12•4•5.5=264

Answer:

A = $7,554.84

A = P + I where

P (principal) = $4,500.00

I (interest) = $3,054.84First, convert R as a percent to r as a decimal

r = R/100

r = 2.73/100

r = 0.0273 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 4,500.00(1 + 0.0273/12)(12)(19)

A = 4,500.00(1 + 0.002275)(228)

A = $7,554.84

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $4,500.00 at a rate of 2.73% per year compounded 12 times per year over 19 years is $7,554.84.

Answer:

[tex]y =11(6)^x[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (0,11)[/tex]

[tex](x_2,y_2) = (2,396)[/tex]

Required

The exponential function

This is represented as:

[tex]y = ab^x[/tex]

In [tex](x_1,y_1) = (0,11)[/tex], we have:

[tex]11 = ab^0[/tex]

[tex]11 = a*1[/tex]

[tex]a = 11[/tex]

So, we have:

[tex]y = ab^x[/tex]

[tex]y = 11b^x[/tex]

In [tex](x_2,y_2) = (2,396)[/tex], we have:

[tex]396 = 11 * b^2[/tex]

Divide both sides by 11

[tex]36 = b^2[/tex]

Taks square roots

[tex]6 = b\\\\b=6[/tex]

So, we have:

[tex]y = 11b^x[/tex]

[tex]y =11(6)^x[/tex]

Answer:

Step-by-step explanation:

The formula for simple interest is ...

  I = Prt

where P is the principal amount loaned, r is the annual rate, and t is the time in years. Solving for interest rate, we get ...

  r = I/(Pt)

We assume 12 months or 52 weeks in a year.
