If F (x) = 5x^3 - 2 and g (x) = x+1, find (f-g) (x)

Answers

Answer 1

Answer: (f-g)(x) is in fact f(x) - g(x):

f(x) - g(x)

= 5x³ - 2 - ( x + 1 )

= 5x³ - 2 - x - 1

= 5x³ - x - 3

A culture started with 2000 bacteria. After 2 hours it few to 2200 bacteria. Predict how many bacteria will be present after 19 hours.

Answers

Answer:

3900 bacteria will be present

Step-by-step explanation:

A culture started with 2000 bacteria and after 2 hours it grew to 2200 bacteria, determining the rate, we can assume that for every hour, 100 bacteria adds onto the culture. Therefore:

If 19 hours have passed, multiply 100 by 19 to insinuate the every hour per 100 bacteria.

19 * 100

1900

Now you can add this to the original starting bacteria:

2000 + 1900

3900 bacteria

the ski team has a race in 3 hours and it is 120 miles away. the team drives 50 miles each hour. will they arrive at the same time?

Answers

They won't arrive exactly when the race starts, but they will arrive before the race starts because, assuming they leave exactly three hours before the race, they can drive a total of 150 miles in three hours (3h*50mi/h). Because they only need to drive 120 miles, they will make it to the race before it starts.

133 is 7% of what number

Answers

$\begin{array}{ccc}7\%&-&133\n\n100\%&-&x\end{array}\n\n7x=133\cdot100\ \ \ /:7\n\nx=(133\cdot100)/(7)\n\nx=19\cdot100\n\nx=1\ 900\to answer$

133 is 7% of 1900.

100/7=14.28571428571429

133 x 14.28571428571429= 1900

1900-93%=133

1900+7%=2033

2033-1900=133

That's the best I can explain it

22. A parallelogram in which one angle 90° is necessarily:A. Square
B. rhombus C. rectangle
D.trapezium

Answers

Answer:

C. Rectangle

Step-by-step explanation:

A parallelogram can not have a single 90° angle. This is because the opposite angles of a parallelogram are equal.

Therefore, the two opposite sides are equal.

In a parallelogram, neighboring angles add up to 180°. This therefore implies that all the angles are 90°.

This describes a rectangle.
