Answer:

about 6 hours

Step-by-step explanation:

[tex]8( {7}^{x} ) = 2( {10}^{6} )[/tex]

[tex] {7}^{x} = 250000[/tex]

[tex]x = \frac{ ln(250000) }{ ln(7) } = 6.39[/tex]

The about 6 hours the bacteria population to reach 2 million.

An exponential equation is an equation with exponents where the exponent (or) a part of the exponent is a variable.

Given that the experiment requires the population of the bacteria to reach 2 million before the experiment can begin.

The reproduction rate of the bacteria can be modeled by the exponential equation,

y = 8 × 7ˣ.

So, according to the question,

8 × 7ˣ = 2 × 10⁶

7ˣ = 250000

x ≈ 6.4

Hence the about 6 hours the bacteria population to reach 2 million.

Answer: 32 m^2

Step-by-step explanation:

first set up your equation; A=A rectange - 2(A square). The you plug in your numbers A = 40-2(4). The you do 40-8 = 32

The exact values are;sin -7π/6 = 0.5; cos -7π/6 = -√3/2; tan -7π/6 = -1/√3; sec -7π/6 = -2/√3; csc -7π/6 =2; cot -7π/6 = -√3

We want to find the six trigonometric functions for  -7π/6 radians.

It should be noted that;

7π/6 radians = -210° degree = -210 +360 = 150° = 5π/6

From the definition of unit circle and applying to what we have here, we can express them as;

sin -7π/6 = 0.5

cos -7π/6 = -√3/2

tan -7π/6 = -1/√3

sec -7π/6 = -2/√3

csc -7π/6 =2

cot -7π/6 = -√3

Answer:

(-8,-10)

Step-by-step explanation:

Rewrite (x+8)2(x+8)² as (x+8)(x+8).

f(x)=3((x+8)(x+8))−10

Expand (x+8) (x+8) using the FOIL Method.

Apply the distributive property.

f(x)=3(x(x+8)+8(x+8))−10

Apply the distributive property.

f(x)=3(x⋅x+x⋅8+8(x+8))−10
Apply the distributive property.

Simplify and combine like terms.

Simplify each term.

Multiply x by x.

f(x)=3(x2+x⋅8+8x+8⋅8)−10

Move 8 to the left of x.

f(x)=3(x2+8⋅x+8x+8⋅8)−10

Multiply 8 by 8.

f(x)=3(x2+8x+8x+64)−10

Add 8x and 8x.

f(x)=3(x2+16x+64)−10

Apply the distributive property.

f(x)=3x2+3(16x)+3⋅64−10

Simplify.

Multiply 16 by 3.

f(x)=3x2+48x+3⋅64−10

Multiply 3 by 64.

f(x)=3x2+48x+192−10

Subtract 10 from 192.

f(x)=3x2+48x+182

The minimum of a quadratic function occurs at x=[tex]-\frac{b}{2a}[/tex] If a is positive, the minimum value of the function is f ([tex]-\frac{b}{2a}[/tex]).

Substitute in the values of aa and b.

x=−[tex]\frac{48}{2(3)}[/tex]

x=-8

Replace the variable x with −8 in the expression.

f(−8)=3(−8)2+48(−8)+182

Y=-10

Therefore, the minimum value is (-8,-10) but if it is asking for just the y-value it would be -10.

Answer:

it's d

Step-by-step explanation:

because you first do 3*4 =12 twice because there are two sides, and do 10*3 twice, and 10*4 twice, and add it all up.

so,

24+60+80=164

answer is d.

Answer:

Option D, [tex]164\ units^2[/tex]

Step-by-step explanation:

Step 1:  Determine the area of the front and back

[tex]A = l * w[/tex]

[tex]A = 10\ units * 4\ units[/tex]

[tex]A = 40\ units^2[/tex]

Step 2:  Determine the area of the sides

[tex]A = l * w[/tex]

[tex]A = 3\ units * 4\ units[/tex]

[tex]A = 12\ units^2[/tex]

Step 3:  Determine the area of the top and bottom

[tex]A = l * w[/tex]

[tex]A = 10\ units * 3\ units[/tex]

[tex]A = 30\ units^2[/tex]

Step 4:  Determine the total surface area

[tex]SA = 2(40\ units^2) + 2( 12\ units^2) + 2(30\ units^2)[/tex]

[tex]SA = 80\ units^2 + 24\ units^2 + 60\ units^2[/tex]

[tex]SA = 164\ units^2[/tex]

Answer:  Option D, [tex]164\ units^2[/tex]

Multiply all terms by x and cancel:

3x+1=x(Simplify both sides of the equation)

3x+1−x=x−x(Subtract x from both sides)

2x+1=0

2x+1−1=0−1(Subtract 1 from both sides)

Step-by-step explanation:

99.5+113= 212.5 /2 = 106.25

Answer:

the width is 1.5meters

Step-by-step explanation:

the perimeter of the fence is 120m

the perimeter= 3w+w+3w+w

120= 3w+w+3w+w

120= 8w

w=1.5m

Answer:

15m

Step-by-step explanation:

Well, she needs 120 meters, which means we already know the circumference (P). P is the sum of all sides.

The lenght (a) is 3 times the width(b).

a = 3b.

Which means if a is x then b is equal to 3x

Since P is the sum of all sides, P is equal to 2a + 2b or 2x + 2*3x = 2x + 6x = 8x

120 = 8x. We are now left with an equation that has one variable only, all we need to do is to divide 120 by 8 to find what x is equal to.

8x = 120

x = 120 / 8

x = 15

We know that width(a) is equal to x, so that's the answer.

Here's a solution you can write:

P = 120m

w = x

l = 3w = 3x

P = 2w + 2l

P = 2*x + 2*3x

P = 2x + 6x

P = 8x

8x = 120

x = 120 / 8

x = 15

w = x -> w = 15m
