The interval where the systolic pressure will be lowest is from 12 PM to 2 PM.

What are the domain and ranges of a function ?

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.

A function S(t) is defined for systolic pressure.

S(t) = { 140 - 6t , for 0 ≤ t ≤ 4 }

S(t) = { 116 , for 4 < t < 8 }

S(t) = {96 + 8t , for 8 ≤ t ≤ 12 }

Let's find the values of systolic pressure [tex]S(t)_{min}[/tex] for each cases.

When , 0 ≤ t ≤ 4

[tex]S(t)_{min}[/tex] = 140 - ( 6 × 4 )

[tex]S(t)_{min}[/tex] = 140 - 24

[tex]S(t)_{min}[/tex] =  116

When , 4 < t < 8

[tex]S(t)_{min}[/tex] =  116

When , 8 ≤ t ≤ 12

[tex]S(t)_{min}[/tex] = 96 + ( 8 × 8)

[tex]S(t)_{min}[/tex] =  96 + 64

[tex]S(t)_{min}[/tex] =  160

So , the lowest value of S(t) will be 116 for for 4 < t < 8  and interval will be from 12 PM to 2 PM.

Therefore , the interval where the systolic pressure will be lowest is from 12 PM to 2 PM.

Answer:

(- 4, 2 )

Step-by-step explanation:

y = 3x + 14 → (1)

2x - 3y = - 14 → (2)

substitute y = 3x + 14 into (2)

2x - 3(3x + 14) = - 14 ← distribute parenthesis on left side and simplify

2x - 9x - 42 = - 14

- 7x - 42 = - 14 ( add 42 to both sides )

- 7x = 28 ( divide both sides by - 7 )

x = - 4

substitute x = - 4 into (1)

y = 3(- 4) + 14 = - 12 + 14 = 2

solution is (- 4, 2 )

Answer:

UV = 12

Step-by-step explanation:

SV = ST + TU + UV ( substitute values )

4x - 29 = 13 + 6 + 2x - 18

4x - 29 = 1 + 2x ( subtract 2x from both sides )

2x - 29 = 1 ( add 29 to both sides )

2x = 30 ( divide both sides by 2 )

x = 15

Then

UV = 2x - 18 = 2(15) - 18 = 30 - 18 = 12

Step-by-step explanation:

Searched it up.

The inverse of the function h(x) = ³√x - 3 is h⁻¹(x) = (x + 3)³.

The given function is-

h(x) = ³√x - 3

Put y = h(x);

h(x) = y =  ³√x - 3

Make x the subject;

x = (y + 3)³

Replace x with h⁻¹(y) = (y + 3)³

Restate with x instead of y.

h⁻¹(x) = (x + 3)³

Thus, the inverse of the function h(x) = ³√x - 3 is h⁻¹(x) = (x + 3)³.

It will take 138 minutes for the repair cost to reach $140

Although part of your question is missing, you might be referring to this full question: A repair company's charge for repairing a certain type of copy machine fits the model y = 47.38 +0.617x. Where y is the number of dollars charged and x is the number of minutes the repair person is on the job. how many minutes would it take for the cost of repair to reach $140? (round to the nearest minute.)

As per the question:

Number of dollars charged by the company = y dollars

Number of minutes the repair person is on the job = x minutes

The cost that needs to be achieved = 140 dollars

Equation:

y = 47.38 + 0.617x------(1)

For the cost of repair to reach $140, substituting $140 in y in equation (1)

140 = 47.38 + 0.617x

Solving further and finding the value of x

140 - 47.38 = 0.617x

92.62 = 0.617x

x = 138 minutes (rounded to the nearest minute)

So, it will take 138 minutes for the repair cost to reach $140

If A,B, and C are the letters selected and we use A twice, B twice, and C once. The number of ways different passwords exist in this scenario are 30.

A password, sometimes known as a passcode (in devices made by Apple, for instance), is a hidden piece of information that is typically a long string of characters and is used to verify a user's identity. Passwords were always thought to be memorized, but today's average person has access to a huge number of password-protected services, making it difficult to remember a different password for each one. The secret is kept by a party known as the claimant, and the person confirming the claimant's identity is known as the verifier, according to the nomenclature of the NIST Digital Identity Guidelines. The verifier can determine the identity of the claimant when the claimant successfully uses a recognized authentication technique to show the verifier that they know the password.

A, B and C are selected

A is used twice B is used twice and C is once
