What is the measure of an angel that turns through 3/4 of a complete circle?

1 answer:

6 0

2/3 think of this as a pie right divided into 3 area but only 2 people eat from it 1 left but how would i complete it if its not done well i need to complete the "pie"
by adding an exponent into the mesure and cacultating a mass of a=mx+b
now you divide and get 0.75
so you will fill in .25 more to get the full measurement by eating 1 more pie:

Find the distance between -3 and 4. A) -12 B) -7 C) -1 D) 7

The answer is 7 because add them to see the distance since it’s both positive if you count the distance it is away from zero so 3+4=7

Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth. 5y2 − 8y = 2 11.2, –9.6 0.22, –1.

Phillipa is a scientist who grows yeast cells. She starts her experiment with 700 yeast cells and notices the growth rate of the

Answer:

700 initial cells
2486 cells after 25 hours

Step-by-step explanation:

#1 There are 700 yeast cells when Phillipa starts her experiment. (This value is given in the problem statement.)

#2 For this, we must assume the time period that is associated with the 5.2% growth. (The problem statement does not specify it.)

The general form of the equation for exponential growth is ...

f(t) = (initial value)×(growth multiplier in time period)^(number of periods)

When the growth (or decay) rate is indicated as a percentage (r), the "growth multiplier in time period" is generally ...

growth multiplier = 1+r

Here, the value of "r" is 5.2% = 0.052, so the growth multiplier in the time period is ...

1 + 0.052 = 1.052

As we said, the time period is not specified. Since the only time period mentioned in the problem is 25 hours, we might reasonably assume that the 5.2% growth occurs in one hour. Then the cell population is ...

f(t) = 700×1.052^t . . . . . . for t in hours

After 25 hours, ...

f(25) = 700×1.052^25 ≈ 700×3.55135 ≈ 2485.9 ≈ 2486

The number of yeast cells present after 25 hours is about 2486.
