Answer:

19

Step-by-step explanation:

Given the following question:

When dealing with absolute value we need to understand that all negatives in between "|  |" are changed into positives. See absolute value (| |) as if its a car wash, and negatives are dirty cars.

In this case...
|-19 |
|-19 |=19
=19

Hope this helps.

Answer:

Absolute value;

The non-negative value of x(in your case -19) without regard to its sign.

Basically how far in distance x(in your case -19) is away from 0.

|–19| = <u>19</u>

A stone is dropped from the edge of a roof, and hits the ground with a velocity of -185 feet per second. How high (in feet) is t
34kurt

Answer:

The height of the roof is 534.8 feet.

Step-by-step explanation:

Let h be the height of the roof.

We know the formula

v^2-u^2=2gh

Since, the stone is dropped from the edge of the roof hence, the initial velocity should be zero. Thus, u = 0

v^2-0=2gh\\h=\frac{v^2}{2g}

Now, we have

v = -185 feet per second

g = 32  feet per square second

On substituting these values, we get

h=\frac{(-185)^2}{2\times 32}\\\\h=534.8

The height of the roof is 534.8 feet.

A quantity with an initial value of 6200 decays continuously at a rate of 5.5% per month. What is the value of the quantity afte
ELEN [110]

Answer:

410.32

Step-by-step explanation:

Given that the initial quantity, Q= 6200

Decay rate, r = 5.5% per month

So, the value of quantity after 1 month, q_1 = Q- r \times Q

q_1 = Q(1-r)\cdots(i)

The value of quantity after 2 months, q_2 = q_1- r \times q_1

q_2 = q_1(1-r)

From equation (i)

q_2=Q(1-r)(1-r)  \\\\q_2=Q(1-r)^2\cdots(ii)

The value of quantity after 3 months, q_3 = q_2- r \times q_2

q_3 = q_2(1-r)

From equation (ii)

q_3=Q(1-r)^2(1-r)

q_3=Q(1-r)^3

Similarly, the value of quantity after n months,

q_n= Q(1- r)^n

As 4 years = 48 months, so puttion n=48 to get the value of quantity after 4 years, we have,

q_{48}=Q(1-r)^{48}

Putting Q=6200 and r=5.5%=0.055, we have

q_{48}=6200(1-0.055)^{48} \\\\q_{48}=410.32

Hence, the value of quantity after 4 years is 410.32.
