Answer:

Step-by-step explanation:

angle 1 and 4 are supplementary so the 2 added together equal 180. 180-124=56.

The sum of the triangles angles equal 180

180-56-58=66 which is the value of angle 2

Haley pays a monthly fee of $20 for her cell phone and then pays 5 cents per minute used. The total cost of Haley’s monthly cell

Leokris [45]

The domain of the function C(m) = 0.05m + 20 is (0, ∞) and the range of the function C(m) = 0.05m + 20 is (20, ∞).

<h3>What is the linear system?</h3>

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

Haley pays a monthly fee of $20 for her cell phone and then pays 5 cents per minute used. The total cost of Haley’s monthly cell phone bill can be expressed by the function

$\rm C(m) = 0.05\ m + 20$

The domain of the function is from zero to infinity because time can never be negative.

Then the range of the function will be

At m = 0, the value of C(m) will be

C(m) = 0.05(0) + 20

C(m) = 20

At m = ∞, the value of C(m) will be

C(m) = 0.05(∞) + 20

C(m) = ∞

Thus, the domain of the function is (0, ∞) and the range of the function is (20, ∞).

Answer:

$1280.59

53 years

Step-by-step explanation:

To find how much we will get in 5 years, we use the formula:

$A=Pe^{rt}$

P = $1200

r = 1.3% or 0.013

t = 5

Now that we have our values, let's plug them into the formula.

$A=1200e^{0.013(5)}$

$A=1200e^{0.065}$

$A=1280.59$

We will have $1280.59 after 5 years.

Now to find how long it will take for our investment to double.

t = ln(A/P)/r

A = 2400

P = 1200

r = 1.3 or 0.013

Let's plug it in.

t = ln(2400/1200)/0.013

t = ln(2)/0.013

t = 53.32 or 53 years

Answer:

$f^{-1}(x) = 4x-3$ is the right answer.

Step-by-step explanation:

I the function is $f(x) = \frac{x+3}{4}$

$f(x)=\frac{1}{4}(x+3)$

Then we have to find inverse of function f(x).

we will write the equation as $y=\frac{1}{4}(x+3)$

4y = x + 3

x = 4y - 3

Now we will rewrite the function as

$f^{-1}(x) = 4x-3$

So the answer is $f^{-1}(x) = 4x-3$

The radii of two circles are in the ratio of 3 to 1. Find the area of the smaller circle if the area of the larger circle is 27

Naddik [55]

ANSWER
$3\pi sq.\: in.$

EXPLANATION

Let R be the radius of the bigger circle and r, be the radius of the smaller circle.

Then their ratio is given as,

$R:r=3:1$

We can rewrite it as fractions to get,

$\frac{R}{r} = \frac{3}{1}$

We make R the subject to get,

$R = 3r$

The area of the bigger circle can be found using the formula,

$Area=\pi {r}^{2}$

This implies that,

$Area=\pi ({3r})^{2}$

$Area=9\pi {r}^{2}$

But it was given in the question that, the area of the bigger circle is 27π.

$27\pi=9\pi {r}^{2}$

We divide through by 9π to get,

$3 = {r}^{2}$

This means that,
$r = \sqrt{3}$

The area of the smaller circle is therefore

$= \pi {( \sqrt{3}) }^{2}$

$= 3\pi$
