1. You start a biology experiment with 4,500 cells. The cells are continuously growing and 2 minutes later

there are about 22583 cells. What is the rate of growth per minute?

Answers

Answer:

80.65% per minute

Step-by-step explanation:

For continous growth :

A = Pe^rt

A = amount after time, t

P = initial amount

r = growth rate

22583 = 4500 * e^r*2

22583 = 4500 * e^2r

22583 / 4500 = e^2r

5.0184444 = e^2r

Take the In of both sides

1.61312 = 2r

r = 1.61312 ÷ 2

r = 0.80656

0.80656 * 100% = 80.65%

I don't understand the problem. Can you help me solve it please? I also have an IEP.

Answers

Answer:

Step-by-step explanation:

The Pythagorean theorem is

a^2+b^2 = c^2 where a and b are the sides and c is the hypotenuse ( the side opposite the right angle)

a^2 + b^2 = c^2

Substitute the known values

5^2 + b^2 = 13^2

25+b^2 = 169

Subtract 25 from each side

25+b^2-25 =169-25

b^2 = 144

Take the square root of each side

sqrt(b^2) = sqrt(144)

b=12

Answer:

Given:

a = 5c = 13

To find:

missing side b

Solution:

Using Pythagorean theorem,

(Hypotenuse² = base² + perpendicular²)

b² = c² - a²

= 13² - 5²

= 169 - 25

= 144

b = √144

= 12

What does A equal: 3(6a+12)=9

Answers

Answer:

a = -3/2

Step-by-step explanation:

3(6a+12)=9

Divide each side by 3

3/3(6a+12)=9/3

6a+12 = 3

Subtract 12 from each side

6a+12-12 = 3-12

6a = -9

Divide by 6

6a/6 = -9/6

a = -3/2

3(6a+12)=9

Find the slope of the line containing the points whose coordinates are (1/,) and (1/,) a. Ab b. A+b/ab c. 1/ab d. A-b/ab

Answers

Answer:

1/ab

Step-by-step explanation:

Complete question

Find the slope of the line containing the points whose coordinates are(a,1/b) and (b,1/a)

Slope is expressed as;

m = y2-y1/x2-x1

Substitute the coordinate values

m = (1/a - 1/b)/b -a

m = (b-a)/ab ÷ b-a

m = (b-a)/ab × 1/b-a

m = b-1/b-a × 1/ab

m = 1 × 1/ab

m = 1/ab

Hence the slope is 1/ab

Christopher's backyard is in the shape of a trapezoid. The bases of the backyard are 30 and 50 feet long. The area of the backyard is 960 square feet. Write and solve an equation to find the height of Christopher's backyard. =12(1+2)ℎ

Answers

Answer:

24 feet

Step-by-step explanation:

The formula for the height of a trapezoid =

h = 2A/ a + b

A = 960 square feet

a = 30 feet

b = 50 feet

h = 2 × 960/30 + 50

h = 1920/80

Factor out the GCF from the given polynomial. 10^3 + 16^2 - 18x 10^3 + 16^2 - 18x = (Type your answer in factored form.)

Answers

Answer:

Step-by-step explanation:

Given the expression 10x^3 + 16x^2 - 18x, we are to find the GCF

First find the factors

10x^3 = 2 * 5 * x * x^2

16x^2 = 2 * 8 * x * x

18x = 2 * 9 * x

From the factors shown, you will see that 2 and x are the common factors. Hence the GCF of the expression is 2x

Part 1: The Easter Bunny wanted the children to have an Easter egg hunt on a soccer field,

which has dimensions of 75 yards by 120 yards. To honor the social distancing restrictions,

each egg must be placed 6 feet apart. What is the maximum number of eggs which can be

placed on the field? Hint: Did you notice the measurement units?

Answers

Answer:

13500

Step-by-step explanation:

to answer this question

convert the dimensions of the field to foot find the area of the fielddivide the area by the space of each egg

1 yard = 3 foot

75 yards = 75 x 3 = 225

120 yards = 120 x 3 = 360 ft

Area of a rectangle = length x width

225 x 360 = 81,000 ft^2

Maximum number of eggs = Area of the field / space the eggs must be apart

81,000 / 6 = 13,500
