Find the size of angle x.

Answer:

A = 60 cm²

Step-by-step explanation:

Given that,

The area of a circle, A = 20 cm²

It is enlarged 3 times.

We need to find the area of the enlarged circle.

Area of the enlarged circle,

A = 20×3

= 60 cm²

So, the area of the enlarged circle is equal to 60 cm².

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:

  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:

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.

__

Car title loan

  r = 125/(500×1/12) = 3 × 100% = 300%

The APR is 300%.

__

Payday loan

  r = 125/(500×2/52) = 6.5 × 100% = 650%

The APR is 650%.

__

Check cashing

  r = 19.66/(478.41×1/52) ≈ 2.1369 × 100% ≈ 214%

The APR is about 214%.

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

[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:

Answer:

[tex]f^{-1}(x) = \frac{\sqrt{x}}{13}[/tex]

Step-by-step explanation:

Inverse function:

Suppose we have a function y = f(x). To find the inverse, we exchange the y and the x values, and then isolate y.

Function:

[tex]f(x) = 169x^2[/tex]

That is:

[tex]y = 169x^2[/tex]

Exchanging x and y:

[tex]x = 169y^2[/tex]

Isolating y:

[tex]y^2 = \frac{x}{169}[/tex]

[tex]y = \sqrt{\frac{x}{169}}[/tex]

[tex]y = \frac{\sqrt{x}}{13}[/tex]

[tex]f^{-1}(x) = \frac{\sqrt{x}}{13}[/tex]

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

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.
