1) 2,064 is divisible by 2,4 and 8 true or false explain. 2 ) 96,240 is divisible by 2,3,5, and 10 true or false explain

1 answer:

8 0

In 1) 2,064 is divisible by all (True), because it is even, the last 2 numbers are divisible by 4, and the last 3 numbers are divisible by 8. 2) Yes (True), because it is even, all digits added up together are divisible by 3, the number ends in 0 0r 5, and the number ends in 0.

Which of the following can be modeled with an exponential function? Select all that apply.

bogdanovich [222]

Answer: The answers are

(ii) The cost to attend Universal Studios increases by 1% each year,

(iii) An endangered species population is decreasing by 12% each year,

(iv) The population of a town that is growing by 5% each year.

Step-by-step explanation: We are given five functions and we are to select those which can be modelled with an exponential function.

(i) Here, height is varying with respect to time, so it will be a linear function.

(ii) Here, the cost to attend Universal Studios is increasing by 1% every year, so this will be an exponential function.

(iii) Here, an endangered species population is decreasing by 12% each year.

So, this will also be an exponential function.

(iv) Since we are considering the distance travelled by the bicycle at a constant speed of 25 mph, so this will be a linear function.

(v) Here also the population is growing by 5% each year. So, the function will be exponential.

Thus, the correct answer is second, third and fifth.

The recipe makes enough stew for 6 people, and the ingredients cost $9.75. How much would it cost to serve 24 people?

Leno4ka [110]

If the recipe makes enough stew for 6 people, and the ingredients cost $9.75, then for 24 people it will cost $x. You can write this statement as

6 people - $9.75,

24 people - $x.

Or as proportion,

$\dfrac{6}{24}=\dfrac{9.75}{x}.$

Find x:

$6\cdot x=9.75\cdot 24,\\ \\x=\dfrac{9.75\cdot 24}{6}=9.75\cdot 4=39.$

Answer: It would cost $39 to serve 24 people

Without solving determine the character of the solutions of the equation x^2+2x+5=0

Sav [38]

★ QUADRATIC RESOLUTION ★

Roots of the given equation will be imaginary because it's discriminant is less than 0 and hence it'll yield imaginary solutions

D < 0

b² - 4ac < 0

4² - 4 ( 5 ) < 0

16 - 20 < 0

-4 < 0

Hence it's character is stated above

Which shows how to solve the equation Three-fourths x = negative 6 for x in one step?

tino4ka555 [31]

Answer:

x = -8

Step-by-step explanation:

Let's put this into numbers: $\frac{3}{4}$ x =-6

The first thing you want to do is to multiply both sides by 4:

3x=-24

Next you need to divide by 3:

x=-8

The answer is -8
