What is the distance from (−4, 0) to (2, 5)? Round your answer to the nearest hundredth. Explain your answer. 7.81 units
8.17 units
8.58 units
10.4 units

Answers

Answer:

A 7.81

Step-by-step explanation:

Use the distance formula to find the distance between coordinates.

$d = √((2--4)^2 + (5-0)^2) \nd = √((2+4)^2 + (5)^2) \nd = √((6)^2 + (5)^2) \nd = √(36 + 25) \nd = √(61) \nd=7.81$

What is the missing exponent?

(2^-5) ????? = 2^-15

Answers

$(2^-^5) ^x = 2 ^ - ^1^5 \n \n ( (1)/(32) ) ^x = (1)/(32768) \n \n \hbox{Solve the exponent.} \n \n ( (1)/(32))^x = (1)/(32768) \n \n\hbox{Take log of both sides} \n \n \hbox{log}} ( (1)/(32)) ^ x = log ( (1)/(32768)) \n \n x * log ((1)/(32) ) = log ( (1)/(32768) ) \n \n \bold{ (log( (1)/(32768)))/(log (1)/(32) ) } \n \n x = 3$

Therefore the missing exponent is 3. Which makes the equation true.

${ \left( { 2 }^( -5 ) \right) }^( x )={ 2 }^( -15 )\n \n { 2 }^( -5x )={ 2 }^( -15 )\n \n \therefore \quad -5x=-15\n \n \therefore \quad x=3$

Remember that:

${ \left( { a }^( m ) \right) }^( n )={ a }^( m\cdot n )$

Which recursive formula can be used to generate the sequence below, where f(1) = 6 and n ≥ 1?6, 1, –4, –9, –14, …

A.)f (n + 1) = f(n) + 5
B.)f (n + 1) = f(n) – 5
C.)f (n) = f(n + 1 ) – 5
D.)f (n + 1) = –5f(n)

Answers

B) because f(2) = f(1) - 5 = 6 - 5 = 1;
f(3) = f(2) - 5 = 1 - 5 = -4;
f(4) = f(3) - 5 = -4 - 5 = -9;
f(5) = f(4) - 5 = -9 - 5 = - 14;

The Answer is B
