Answer:

False

Step-by-step explanation:

Actual question is:

logf 4(3d) + log4 1 = log4 3d

Solution:

logf 4 + logf (3d) + 0 = log4 (3d)
logf 4 + logf (3d) = log4 (3d)

If we assume f = 4, then

log4 4 + log4 (3d) = log4 (3d)
log4 4 = 0

but log4 4 = 1

1 = 0 is impossible

Therefore the statement is False

Answer:

m∠ABC = m∠BED; Corresponding Angles Theorem

Step-by-step explanation:

Given: line BC is parallel to line ED m∠ABC = 70° m∠CED = 30°

Prove: m∠BEC = 40°

Statement Justification

1. line BC is parallel to line ED - Given

2. m∠ABC = 70° - Given

3. m∠CED = 30° - Given

4. m∠BEC + m∠CED = m∠BED - Angle Addition Postulate

5. m∠ABC = m∠BED - Corresponding Angles Theorem

6. m∠BEC + 30° = 70° - Substitution Property of Equality

7. m∠BEC = 40° Subtraction Property of Equality

Given that f(1)=2 and f'(1)=4, find the derivative of f(x)loge(x) when x=1

inessss [21]

Answer:

Step-by-step explanation:

loge(x) is ln(x)

f(x) × ln(x)

Differentiate using product law

[ln(x) × f'(x)] + [(1/x) × f(x)]

x = 1

[ln(1) × f'(1)] + [(1/1) × f(1)]

(0 × 4) + (1 × 2)

0 + 2
