Hello there!

When finding the domain of a function, the only things you need to watch for are...
1. Variables under even radical signs
2. Variables in the dominator of fractions
3. Logarithms

Since this function is linear, there is nothing that would stop any real number from being part of the domain.

This means that the domain is all real numbers. (-∞,∞)

I hope this helps!
Best wishes:)

A 2.8 m ladder is to be laid against a wall so that the top of the ladder is 2 m up the wall. How far out from the base of the w
natta225 [31]

Given :

A 2.8 m ladder is to be laid against a wall so that the top of the ladder is 2 m up the wall.

To Find :

How far out from the base of the wall should the ladder be placed.

Solution :

We know, the angle between floor and height is 90° .

Now, length of ladder, l = 2.8 m .

Height of wall, h = 2 m .

Let, distance between base of the wall and ladder is b .

l^2 = h^2 + b^2\\\\b = \sqrt{l^2 - h^2}\\\\b = \sqrt{2.8^2 - 2^2}\ m\\\\b = 1.96 \ m

Hence, this is the required solution.

Ellen now has $125. how much would she have after 8 years if she leaves it invested at 8.5% with annual compounding?
liraira [26]

We know the formula for compound interest as

A=P(1+\frac{r}{n})^{nt}

Now, we have been given that Ellen has $125. It means we have

P = $125

From the given directions, we have

r=0.085\\
t=8\\
n=1

On substituting these values in the above mentioned formula, we have

A=125(1+\frac{0.085}{1})^{1\times 8}\\
\\
A=\$240.08

Therefore, Ellen would have $240.08 after 8 years.

Determine the discount between the point(-4,2) and the line 4y=3×+6​
Savatey [412]

Answer:

d = 14/5

Step-by-step explanation:

The point (-4,2) means that;

At x = -4, y = 2

Now general form of a linear equation is;

Ax + By + C = 0

We are given;

4y = 3x + 6​

Rearranging to the form of a linear equation gives;

3x - 4y + 6 = 0

Thus, A = 3, B = -4 and C = 6

Thus, at point (-4,2), distance between them is;

d = (3(-4) - 4(2) + 6)/√(3² + (-4)²)

d = -14/5

We will take the absolute value.

Thus; d = 14/5
