What is the y intercept of the function f(x)=2•3^x

kykrilka [37]

Answer:

$\boxed{Option \ A}$

Step-by-step explanation:

$f(x) = 2*3^x$

y intercept is when x = 0

So, Putting x = 0 in the above function

=> f(0) = $2*3^0$

=> f(0) = 2*1

=> f(0) = 2

So, y-intercept is (0,2)

You have an office building that is 600 square feet in area. What are two possible dimensions how your office could be construct

stepan [7]

Answer:

$20\ ft$ by $30\ ft$

$15\ ft$ by $40\ ft$

Step-by-step explanation:

In this problem I'm assuming the office is rectangular.

so

The area of rectangle is equal to

$A=LW$

where

L is the length of the rectangle

W is the width of the rectangle

In this problem we have

$A=600\ ft^{2}$

so

$600=LW$ ------> equation A

Find two possible dimensions of the office

case A) Assume a length side L and find the value of W in the equation A

so

For $L=30\ ft$

substitute in the equation and solve for W

$600=(30)W$

$W=600/30=20\ ft$

The dimensions are $20\ ft$ by $30\ ft$

case B) Assume a length side L and find the value of W in the equation A

so

For $L=40\ ft$

substitute in the equation and solve for W

$600=(40)W$

$W=600/40=15\ ft$

The dimensions are $15\ ft$ by $40\ ft$

Can somebody help with number 4 asap please

Mars2501 [29]

Answer:

x ≈ 41

Step-by-step explanation:

All the angles in a quadrilateral add together to equal 360°

So set up the equation:

a + b + c + d = 360°

Now fill in the values we know:

x + _ + 4x + 2x - 10 + 85 = 360

7x + 75 = 360

Now subtract both sides by 75:

7x + 75 - 75 = 360 - 75

7x = 285

Divide both sides by 7:

7x / 7 = 285 / 7

x = 40.714

Round:

x = 41

Now to check our answer, substitute 41 for x in the equation:

(41) + _ + 4(41) + 2(41) - 10 + 85

(41) + 164 + 82 - 10 + 85 = 362

The answer is close to 360, so we know it is correct

State true or false. (i) Cube of any odd number is even. F (ii) A perfect cube does not end with two zeros.T (iii) If square of

lilavasa [31]

i. Cube of any odd number is even. False

ii. A perfect cube does not end with two zeros. True

iii. If square of a number ends with 5, then its cube ends with 25. False

iv. There is no perfect cube which ends with 8. False

v. The cube of a two digit number may be a three digit number. False

vi. The cube of a two digit number may have seven or more digits. False

vii. The cube of a single digit number may be a single digit number. True

<h3>Reasons </h3>

i. Cube of any odd number is even. This statement is false because the cube of odd numbers are also odd

ii. A perfect cube does not end with two zeros. This statement is True because the cube of a two digit number cannot be a 3 digit number and therefore cannot end with two zeros.

iii. If square of a number ends with 5, then its cube ends with 25. This statement is False

Using the illustration

35^2 = 35 x 35= 1225 , its square ends with 5

35^3= 35 x 35 x 35= 42875 which ends with 75

iv. There is no perfect cube which ends with 8. This statement is False.

Using the illustration, the cube of 2 is given thus

2 * 2 * 2 = 8

The cube of 2 ends with 8

v. The cube of a two digit number may be a three digit number. This statement is False.

Using the illustration, 10 is a two digit number

10 * 10 * 10 = 1000

The cube of 10 which is a two digit number is not a three digit number and same applies to all two digit numbers

vi The cube of a two digit number may have seven or more digits. This statement is False because the cube of a two digit number can only be a four digit number.

vii. The cube of a single digit number may be a single digit number. This statement is True because the cube of a single digit number can be a single, two or three digit number.
