F(x) = 7x + 4
Answer: f’(x)=7

Steps:
1. Take the derivative of both sides

2. Use differentiation rule

3. Find the derivative

4. Removing doesn't change the value, so remove it from the expression

5. Solution f’(x)=7

Answer:

7 d/dx[x^4]

Step-by-step explanation:

Since 7 is constant with respect to x, the derivative of 7x^4 with respect to x is 7 d/dc [x^4]

- If MML = (11x - 5), mJK = (4x + 26)° and mZMNL = (10x – 12), find mZMNL.

GenaCL600 [577]

Answer:

m∠ MNL = 78º

Step-by-step explanation:

Arcs meassures

mML = (11x - 5)º

mJK = (4x + 26)°

Angle meassure

m∠MNL = (10 x – 12)º

______________________

angle measure = average of arcs

m∠MNL = (mML+ mJK)/2

Replacing

(10x – 12)º = ((11x - 5)º + (4x + 26)° )/ 2

10x -12 = (15x + 21 )/2

10x - 7.5x = 10.5 + 12

2.5x = 22.5

x= 9

m∠MNL = (10 x – 12)º

= 90 - 12

= 78º

Complete the recursive formula of the geometric sequence 16\,,\,3.2\,,\,0.64\,,\,0.128,...16,3.2,0.64,0.128,

Nastasia [14]

Answer:

$a_{n+1}=0.2a_n$ for all n>0, $a_1=16$

Step-by-step explanation:

Let $\{a_n\}=\{16,3.2,0.64,0.128,\cdots \}$ be the sequence described.

A geometric sequence has the following property: there exists some r (the ratio of the sequence) such that $\frac{a_{n+1}}{a_n}=r$ forr all n>0.

To find r, note that

$\frac{3.2}{16}=\frac{32}{10(16)}=\frac{2}{10}=\frac{1}{5}=0.2$

Similarly

$\frac{0.64}{3.2}=\frac{64}{10(32)}=\frac{1}{5}=0.2$

$\frac{0.128}{0.64}=\frac{1}{5}=0.2$

Thus $a_{n+1}=r a_n=\frac{a_n}{5}=0.2a_n$ for all n>0, and $a_1=16$

Every morning Jenna runs for 20 min . If Jenna runs 6 miles per hour , how far does she travel

DerKrebs [107]

20 minutes* (1 hour/ 60 minutes)* (6 miles/ 1 hour)= 2 miles.
(Note that the units cancel out so you end up getting the answer)

The final answer is 2 miles~
