If f(x) = x2, then f(4) = 42 = 16. Find:<br> a. f(1)<br> b. f(-3)<br> c. f(t)
icang [17]

Answer:

Step-by-step explanation:

f(x) = x²

f(4) = 4² = 16

f(1) = 1² = 1

f(-3) = -3² = 9

f(t) = t²

Always wise to us the ^ symbol to represent powers to avoid confusion

4^2 = 4² = 16

-3^2 = 9

t^2

if you are on a PC, the square symbol (²) can be typed by holding down the "alt" key while pressing and releasing "2","5","3" on the keypad, then release "alt". Unfortunately this does not work if you only have the row of numbers on the keyBoard to work with.

The difference between seven times a number and 9 is equal to three times the sum of the number and 2. Find the number
murzikaleks [220]

Answer:

Number:3.75

Equation:7 x-9=3(x+2)

Step-by-step explanation:

Let the number be x.

According to the question,

7 x-9=3(x+2)

7 x-9= 3 x+ 6

7 x- 3 x= 9+6

4 x= 15

x=15/4

x=3.75

If you verify the answer you will get,

11.25=11.25

Thank you!

What is the distance between (-4,6) (3,-7)
dalvyx [7]

Answer:

The answer is

<h2>\sqrt{218}  \:  \: or \:  \: 14.76 \:  \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-4,6) and (3,-7)

The distance is

<h3>d =  \sqrt{ ({ - 4 - 3})^{2} +  ({6 + 7})^{2}  }  \\  =  \sqrt{( { - 7})^{2}  +  {13}^{2} }  \\  =  \sqrt{49 + 169}  \:  \:  \:  \:  \:  \:  \:  \\  =  \sqrt{218}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 14.7648230602</h3>

We have the final answer as

<h3>\sqrt{218}  \:  \: or \:  \: 14.76 \:  \:  \: units</h3>

Hope this helps you
