#5 is very nicely and correctly done.

#7 says: "No matter what X may be, this function of it is always 9 more than 1/2 of X .".

That's a very powerful statement. Now you know that if X is ever 2, the function will be 1/2(2)+9 which is 10.

If X is ever zero, the function will be 1/2(0)+9 which is 9. If X is ever a cow, the function will be 1/2 of a cow, plus the number 9. Which makes no sense, but that's what the function says.

So, when X is -8, the function is 1/2 of -8, plus 9. Which is 5 ... the 'f' of -8.

Whatever X happens to be at the moment, just write that number in place of X in the function, and it'll show you the function of what X is.

f(a bazillion) = 1/2(a bazillion) + 9 .

f(a-28) = 1/2(a-28) + 9 (but simplify it)

Write these numbers in a smallest order 33%, 1/3, 0.3, π x 10-1

aniked [119]

Answer:

0.3, 33%, 1/3, pi x 10-1

Step-by-step explanation:

Let's simplify all of them so that they're in the same form. 33% is 0.33 as a decimal, since a percentage is out of 100. 1/3 is equal to 0.33333 repeating as a decimal--This one is just one that you have to memorize. 1 divided by 3 will give you your answer. Next, pi multiplied by 10: pi is roughly 3.14159 to the hundred-thousandths place. So we multiply that by 10, giving us 31.4159. -1 gives us 30.4159.

So:

0.3, 33%, 1/3, and lastly pi x 10-1

The answer is 185 ft 2.

Since it is a parralellogram you have to multiply the base x height.
And it has a 2 right next to it because you multiplied base x height

Hope it helps!~

Courtney walked from her house to the beach at a constant speed of 4 kilometers per hour, and then walked

RUDIKE [14]

The system of equations that represents this situation are:

q + p = 2

4q + 5p = 8

Solution:

Let q be the number of hours it took Courtney to walk from her house to the beach

Let p be the number of hours it took her to walk from the beach to the park

The entire walk took 2 hours

Therefore,

q + p = 2 ------- eqn 1

The total distance Courtney walked was 8 kilometers

Total distance = 8 km

Courtney walked from her house to the beach at a constant speed of 4 kilometers per hour

Then walked from the beach to the park at a constant speed of 5 kilometers per hour

Distance is given as:

$distance = speed \times time$

From her house to the beach:

$distance = 4 \times q = 4q$

From the beach to the park:

$distance = 5 \times p = 5p$

We know that,

Total distance = 8 km

Therefore,

4q + 5p = 8 ------ eqn 2

Thus the system of equations that represents this situation are:

q + p = 2

4q + 5p = 8

Interest = 650$

Step-by-step explanation:

Given:

Invest Inv = 2000$, interest rate r = 6.5% compounded annually

and time n = 5 years

Formula for calculation is:

Int = (Inv · r · n) / 100

Int = (2000 · 6.5 · 5) / 100 = 650$

Int = 650$

God with you!!!
