Answer:

29 is your answer. I hope this helps you! Let me know if I got something wrong or if you need more help :)

Step-by-step explanation:

First, apply distributive property to 3(2+8). 3×2 and 3×8.

15 + (6 + 24) - 4^2

Add 6 and 24.

15 + 30 - 4^2

Simplify 4^2. 4^2 is the same as 4×4. 4 times 4 is 16.

15 + 30 - 16

Add 15 and 30.

45-16

Subtract.

Two friends share a secret on the first day. The second date they each till one another different friend, so now for people know
goblinko [34]

Answer:

The 20th day

Step-by-step explanation:

On the first day, number of people who know the secret=2

Number of people On the second day =2X2=4

Number of people On the third day =4X2=8

We can see that on each passing day, the number keeps doubling.

This is an example of a geometric progression.

Now we are to determine the number of days when the number of people who know the secret will grow past 1,000,000

For the G.P. 2,4,8,...

a=2, common ratio, r= 2

Uₙ=arⁿ⁻¹

arⁿ⁻¹>1000000

2X2ⁿ⁻¹>1000000

2ⁿ⁻¹⁺¹>1000000

2ⁿ>1000000<2²⁰=1048576

2ⁿ<2²⁰

n<20

It means on the 20th day, more than 1 million people will have been told the secret

A number pattern starts with 10 and follows the rule multiply by 3 What is true
lesya692 [45]

Answer:

B) They have a 0 in the ones place.

Step-by-step explanation:

Given

Number pattern that starts with 10.

Rule: Multiply by 3

Required

Select which statement is truth of the pattern.

First, the pattern needs to be listed out.

Given that the pattern starts from 10 and progresses by multiplying current term by 3.

The pattern is as follows;

10, 30, 90, 270, 810, 2430, 7290, .....

By comparing the given options with the above pattern of numbers. We have:

A) They are odd numbers.

This statement is false because the above pattern of numbers are all even and can never be odd

B) They have a 0 in the ones place.

This statement is truth because all the numbers in the above progression ends in 0. This 0 represents the unit of one's place.

Hence, this statement is truth.

C) They have a 3 in the tens place.

This statement is false;

This is so because they have different digits at tens place. The tens place is the digit prior to the last digit of each number.

D) They can be odd or ever numbers.

As pointed out in (A) above, the number can only be even number because the progression starts with an even number (10) and irrespective of what it's been multiplied by, it'll always remain an even number.

Hence,

Only option B is correct/truth.

Others are incorrect

For BRAINLIEST:Finding Critical points &amp; Extreme values. #47 &amp; #61 Please provide a clear explanation that is understand
almond37 [142]
Start with #47.  To find the critical values, you must differentiate this function.  x times (4-x)^3 is a product, so use the product rule.  The derivative comes out to f '(x) = x*3*(4-x)^2*(-1) + (4-x)^3*1 = (4-x)^2 [-3x + 4-x]
Factoring this, f '(x) = (4-x)^2 [-3x+4-x] 
Set this derivative equal to zero (0) and solve for the "critical values," which are the roots of   f '(x) = (4-x)^2 [-3x+4-x].  (4-x)^2=0 produces the "cv" x=4.
[-3x+ (4-x)] = 0 produces the "cv" x=1.   Thus, the "cv" are {4,1}.

Evaluate the given function at x: {4,1}.  For example, if x=1, f(1)=(1)(4-1)^3, or 2^3, or 8.  Thus, one of the extreme values is (1,8).
