If the domain of the square root function f(x) is x<7, which statement must be true?

Delicious77 [7]

Answer:

The x-term inside the radical has a negative coefficient

Step-by-step explanation:

The argument of a square root should be ALWAYS greater or equal to zero. If the domain of the function is x<7, rearranging, we have: 0<x-7

Therefore the argument is: x-7, and the function is: y = √(x-7)

The statement "The x-term inside the radical has a negative coefficient" is the right answer.

The map of a biking trail is drawn on a coordinate grid. The trail starts at P(−2, 2) and goes to Q(5, 2). It goes from Q to R(5

love history [14]

Answer:

The total length (in units) of the biking trail is 17 units.

Step-by-step explanation:

o find distance between points A(x¹, y¹) and B(x², y²), we use formula:

$d = \sqrt{(x^{2}-x^{1})^{2}+(y^{2}-y^{1})^{2}}$

The trail starts at P(−2, 2) and goes to Q(5, 2).

So, the distance PQ will be calculated as:

$PQ = \sqrt{(5^{}-(-2)^{})^{2}+(2^{}-2^{})^{2}$

$PQ = \sqrt{(49^{}+0)$

PQ = 7 units

Then the trail goes from Q(5, 2) to R(5, −5).

So, the distance QR will be calculated as:

$QR = \sqrt{(x^{2}-x^{1})^{2}+(y^{2}-y^{1})^{2}}$

$QR = \sqrt{(5^{}-5^{})^{2}+(-5^{}-2^{})^{2}$

QR = 7 units

And then from R(5, −5) to S(8, −5).

$RS = \sqrt{(8^{}-5^{})^{2}+(-5^{}-(-5)^{})^{2}}$

QR = 3 units

Hence, the total length of the biking trail is:

PQ + QR + QR = 7 + 7 + 3 = 17 units

Here are some numbers written in standard form. From these numbers write down/

ELEN [110]

Answer:

When we have a number like:

1.0x10^n

To rewrite this in standard form, we need to:

if n is positive, we move the decimal point n times to the right, adding zeros when necessary.

1.0x10^3

n = 3. then we add 3 zeros between the one and the decimal point, this is:

1.0x10^3 = 1000

if n< 0, then we move the decimal point n times to the left.

If we had:

1.0x10^-3

We move the decimal point 3 times to the left, adding zeros as this is needed.

1.0x10^-3 = 0.001

if n = 0, we have:

1.0x10^0 = 1.0

Now let's rewrite all the given numbers:

A) 3.4x10^-1 = 0.34

B) 1.36x10^6 = 1360000

C) 7.9x10^0 = 7.9

D) 2.4x10^5 = 240000

E) 5.21x10^-3 = 0.00521

F) 4.3x10^-2 = 0.043
