Answer:

choose the first

Step-by-step explanation:

When h=0, T is the highest (because the temperature is highest at noon)

And knowing that the temperature difference in the world cannot exceed 60 degrees in a day, only the first choice is common sense.

A base of ten raised to a negative exponent corresponds to a number that is-
Masteriza [31]

Answer:

A base of ten raised to a negative exponent corresponds to a number that is between 0 and 1.

Step-by-step explanation:

A base of ten raised to a negative exponent, say - 1 will correspond to the number, 10^{- 1} = \frac{1}{10^{1}} = \frac{1}{10}.

Again, a base of ten raised to a negative exponent, say - 2 will correspond to the number, 10^{- 2} = \frac{1}{10^{2}} = \frac{1}{100}.

{Since we know the property of exponents as x^{- a} = \frac{1}{x^{a}}}

Therefore, all those numbers are between 0 and 1.

Hence, a base of ten raised to a negative exponent corresponds to a number that is between 0 and 1. (Answer)

Thirty-five less than the square of a number is the same as 2 times the number. Find the number
Nookie1986 [14]

9514 1404 393

Answer:

  -5  or  7

Step-by-step explanation:

Let x represent the number. The problem statement tells us ...

  x^2 -35 = 2x

  x^2 -2x -35 = 0 . . . . subtract 2x to put in standard form

  (x -7)(x +5) = 0 . . . . . factor

  x = 7  or  x = -5 . . . . solutions are values of x that make the factors zero

The number could be either -5 or +7.

Q1: Payments of $ 670 are being made at the end of each month for 5 years at an interest of 8% compounded monthly. Calculate the
Jlenok [28]

Answer:

So, the present accumulated value is, $ 49557.69

Step-by-step explanation:

According to the question, payments of $ 670 are being made at the end of each month for 5 years at an interest of 8% compounded monthly. So, present accumulated value, =

$ \sum_{x = 1}^{60}670 \times (1 + \frac{8}{12 \times 100})^{x}

= $ (670 \times (\frac {(1 + \frac {2}{300})^{61} -  ( 1 + \frac{2}{300})}{\frac{2}{300}})

\simeq $ 49557.69

So, the present accumulated value is, $ 49557.69

Write a function rule for the table
Elza [17]

The function rule for the table is y = 25/4 x

<h3>Equation of a linear function</h3>

The standard expression for a linear function is expressed as y =mx + b

where

m is the slope

b is the y-intercept

Using the coordinate points (4, 25.00) and (8, 50.0)

Determine the slope

Slope = 50-25/8-4

Slope = 25/4

Determine the y-intercept

50 = 25/4(8) + b

50 = 25(2) + b

50 = 50 + b

b = 0

Hence the function rule for the table is y = 25/4 x
