Father is four times older than his son. In 14 years the father will be twice as old. What are their current ages?

wariber [46]

Answer:

---

Step-by-step explanation:

The son’s age is unknown, so call it: X

The father’s age, four times older, so that means: 4*X= 4X (I use * for multiply)

After 16 years, we add 16 to both ages:

Son: X+16

Father: 4X+16, now, after 16yrs father’s age 2x older than son:

father→ 4X+16 = 2(X+16) = 2X+32 (father twice older than the son age)

4X +16= 2X+32 (after opening the brackets)

4X-2X= 32 - 16 ——-> we moved 2X to left, turned minus -, we moved 16 to the right turned minus -

2X = 16

X = 16/2 = 8

Son’s age is 8 yrs old

Father(Sunil) age is 4x8= 32

After 16 yrs, Father’s age twice older:

8+16=24 (son)

32+16= 48 (Father,Sunil, twice older than son)

Which statements accurately describe the function f(x) = 3(16)^3/4 ?

photoshop1234 [79]

Answer:

3rd and 5th options

Step-by-step explanation:

For f(x) = 3(16)^(3x/4):

There is no initial value, because exponents can be any real number (positive or negative), so #1 is false

Because exponents can be any real number (positive or negative), #2 is false

A positive number to the power of anything will always be positive, and not equal to 0, so #3 is true

The simplified value of this is 3((16)^(3/4) )^x = 3(2^3)^x = 3(8)^x, so #4 is false, but #5 is true.

The position of a particle moving along the x-axis is given by s(t)=5t2+3. Use difference quotients to find the velocity v(t) an

leva [86]

Answer:

$v(t) = 10t$

$a(t) = 10$

Step-by-step explanation:

The velocity is the derivative of the position.

The acceleration is the derivative of the velocity.

In this problem, we have that:

$s(t) = 5t^{2} + 3$

Looking at the derivative table, the derivative of $a*t^{n}$ is $a*n*t^{n-1}$ and the derivative of a constant is 0.

So:

$v(t) = s'(t) = 10t$

$a(t) = v'(t) = 10$

Your answers are correct.
