Answer:

64π square feet (the formula for the area is r^2π so you have to multiply 8 with itself and you get 64. 64×π is 64π)

Write an equation of the line passing through the given point and satisfying the given condition. Give the equation (a) in slope
Mariana [72]

Answer:

(a) y=8x-46

(b) 8x-y=46

Step-by-step explanation:

-y=-8x+4

y=8x+4

We know that 8 is the slope, and if we need a equation parallel to this line, then it will have the same slope.

Substitute (6,2)

2=8(6)+b

2=48+b

b=-46

The final answer is y=8x-46

Gary is testing a river water sample in his lab. Initially, there are 64 bacteria in the river water sample. The number of bacte
rusak2 [61]
<h2>Hello!</h2>

The answers are:

- The quantity that represents the initial number of bacteria is <u>64.</u>

- The quantity that represents the rate at which the number of bacteria is increasing is (1+0.12) or <u>1.12</u> which means the growth rate percentage for the bacteria is 0.12 or (0.12*100), it will be <u>12%.</u>

<h2>Why?</h2>

To solve the problem, and complete the statements, we need to remember the form of the exponential growth.

The exponential growth formula is given by the following formula:

P(t)=StartAmount(1+PercentageRate)^{t}

Where,

Start Amount, is the starting population or amount.

(1+Percentage Rate), is the increasing rate

Percentage Rate, is the growth rate percentage.

t, is the time elapsed.

Now, we are given the following expression:

P(3)=64(1.12)^{3}

Which can be rewrited as:

P(3)=64(1+0.12)^{3}

So, we have that:

- The quantity that represents the initial number of bacteria is 64.

- The quantity that represents the rate at which the number of bacteria is increasing is (1+0.12) or 1.12 which means the growth rate percentage for the bacteria is 0.12 or (0.12*100), it will be 12%.

Have a nice day!

PLEASE HELP!!!!! Geometry
barxatty [35]

Answer:

53°

Step-by-step explanation:

i will use ∩ to represent arc since there is no arc sign

if ∩EF = 34, then ∡EFC = 34

think of EFC as an angle in the larger circle

since EFC = 34, ABC = 34 because they are opposite angles and opposite angles are always congruent.

ABD = AB + BD = 19 + 34 = 53

Rewrite the following expression without using absolute value. lz-6l-lz-5l if z&lt;5
MA_775_DIABLO [31]

The expression without using absolute value is 2z - 11

<h3>Absolute value of a function</h3>

Given the expression with absolute value expressed as:

lz-6l-lz-5l

Since absolute function can both be negative or positive, hence;

lz-6l-lz-5l = z - 6 - -(z - 5)

lz-6l-lz-5l = z-6-(-z+5)

lz-6l-lz-5l = z - 6 + z - 5

lz-6l-lz-5l = 2z - 11

Hence the expression without using absolute value is 2z - 11
