A light post is 4 ft tall and cast a shadow of 5 ft. Find the distance between
the top of the post and the end of the shadow.

O 9 ft
O 6.4 ft
O 3 ft
O 4 ft

Answers

Answer 1

Answer:

6.4 ft

Step-by-step explanation:

Let “a” be the light post height

Let “b” be the length of the shadow

Let “c” be the distance from the top of the light post to the end of the light post’s  shadow.

Then:

(a X a) + (b X b) = c X c

The Pythagorean Theorem will work pretty well here:

(4 X 4) + (5 X 5) = 16 + 25 = 41

The square root of 41 is: 6.4023

So, about 6.4 ft from the top of the post to the end of the shadow

Answer 2

Answer:

6.4ft

Suppose you take 340 mg of a certain medication.
The amount of medication in your body decreases by 32% per hour.

Write a function for M(h), the number of milligrams of the medication in your body after h hours

Answers

Answer:

m= 340 × 0.68h

Step-by-step explanation:

Given that

You take 340 mg of the certain medication

And, the amount of medication would be reduced by 32% per hour

So we need to the find the function for M(h)

Here M denotes the milligrams

And, the h denotes the hours

So, the function would be

m = 340 × (1 - 0.32)h

m= 340 × 0.68h

The same would be considered and relevant

How to identify the place value of a digit in a number?

The place values on the left of the decimal point start as ones, tens, hundreds, and so on. The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths, and so on

Given that the password contains five digits, such as 17467.

In general total digits = 10  [ from 0 to 9]

If a password contains five digits, then by the fundamental principal of counting, then the total number of different passwords;

6x(10x2 + 8x + 2)
12x(5x2 + 4x + 2)

Answers

The answer is B. 12(5x^2+4x+2)

Answer: 12(5x2 + 4x + 2) is correct answer

Step-by-step explanation:

60x2 + 48x + 24  

if we take 6 as a common factor

6(10x^2+8x+4)     so first option is not true

if we take 12 as a common factor

12(5x2 + 4x + 2)

6x & 12x can not  be taken as common factor..

so the correct option is 2nd one..

3 numbers are in arithmetic progression their sum is15 and their product is 80 determine the 3 numbers

Answers

Answer:

2, 5, 8

Step-by-step explanation:

For starters, let us assume that the numbers are x-d, x, and x+d.

Where d is the common difference between terms.

This mean that we can say, from the question

x-d + x + x+d = 15

3x = 15,

x = 5,

This means that the terms are 5, 5-d and 5+d.

On the other hand,

(5-d) * 5 * (5+d) = 80

(5-d) * (5+d) = 80/5

(5-d) * (5+d) = 16

25 - d² = 16

d² = 9

d = + or - 3.

Finally, the three numbers will be 2, 5, and 8. On the flipside, their sum and product are 15 and 80.
