find the product:42(100,000)

It's C.

Basically, when youre dividing something, the bases would stay the same but the exponents would change. For division, you'd have to substract the exponent of the denominator from the denominator (of like bases, of course)

In this case, it's 10^8-(-3).

The only reason it's not 10⁵ is because of the negative 3. If it were a positive 3, it would become 10⁵.

Answer:

The answer is A. f(x) = 5000(0.4)x, with a horizontal asymptote of y = 0, because 2,000 of the bacteria remain alive.

Step-by-step explanation:

Answer:

The correct option is A.

Step by step explanation:

The exponential function is defined as

Where, a is initial value and b is growth factor or decay factor.

The initial population of bacteria is 5000.

After each day of treatment, 40% of the sample remains alive. It means the growth factor or decay factor is

Therefore the required function is

The horizontal asymptote is y=0 because

Therefore option A is correct.

Answer:

a) $654

b) 27 unidades cuadradas

c) 721

Step-by-step explanation:

a) ¿Cuál es el valor de un bolígrafo cuando la docena se compra por $ 7848?

Una docena = 12

Por eso:

12 bolígrafos = $ 7848

1 bolígrafo = $ x

Cruz multiplicar

12 bolígrafos × $ x = 1 bolígrafo × $ 7848

$ x = 1 bolígrafo × $ 7848/12

$ x = $654

b) Área de un triángulo ¿9 unidades de base y 6 unidades de altura?

Área de un triángulo =

= 1/2 × Base × Altura

1/2 × 9 × 6

= 27 unidades cuadradas

c) Cien veces la suma de 4.5 con 2.71

Esto se calcula como:

100 × (4,5 + 2,71)

= 100 × (7.21)

= 721

Answer:

0.867 in decimal form

13/15 in fraction form

Step-by-step explanation:

1. Add

2/3 + 1/5 = 10/15 + 3/15

2. Simplify the sum, 13/15

1 is the greatest common divisor of 13 and 15. The result can't be further reduced.

3. Convert 13/15 into a decimal.

Answer:

103 ft^2

Step-by-step explanation:

Long sides: 2(8*4) = 64 ft^2

Under side: 3*8 = 24 ft^2

Triangles: (2(3*5))/2 = 15 ft^2

64+24+15 = 103

Answer:

103

Step-by-step explanation:

the base = 3x8 = 24

the sides are= 4 x 8 = 32

two sides = 64

triangle = 5x 3 x1/2 = 7.5

7.5 x 2 = 15

total = 103

Answer:

 s =  120

Step-by-step explanation:

Explanation:-

Given

               [tex]s = ut + \frac{1}{2} at^{2}[/tex]

Substitute 'u =14 , a= 8 and t=4

             [tex]s = 14 (4) + \frac{1}{2} 8(4)^{2}[/tex]

            s = 56 + 64

            s =  120

V = 21 x 7

V = 147 cubic meters

Answer:

72 degrees for each exterior angle and 360 degrees for all of them summed.

Step-by-step explanation:

An exterior angle of a polygon is the angle between the line extending one of its sides and the next side.  As you go around a regular n sided polygon doing this, you will rotate through a complete circle of 360 degrees.  All these angles are equal, so each one is 360/n.

For the pentagon, n=5, so the sum of all its exterior angles is 360 degrees and each exterior angle is 360/5=72 degrees.

Answer:

D

Step-by-step explanation:

A.

y= 6x³

to find the inverse substitute x for y and y for x and solve for y

x= 6y³ ; divide both sides by 6

x/6 =y³ ; cube root both sides

(∛x)/ ∛6 = y

so  (∛x)/6  and 6x³ are NOT inverse of each other

B

y= (x+2)/5

x= (y+2)/5; multiply by 5

5x = y+2; subtract 2

y= 5x-2 NOT corect

C

y = 5x-6

x= 5y-6; add 6 to both sides

x+6 = 5y ; divided by 5 both sides

y = (x+6)/5 is NOT correct

D

y=7x -2

x= 7y-2

x+2 = 7y , (x+2) /7 = y so  IS correct

Answer:

y(-6)=6

y(-3)=4

y(0)=2

y(3)=0

y(6)=-2

Step-by-step explanation:

Just substitute the domain by x every time and add that next to y for your answer

Answer:

x=-1, 5/2.

Step-by-step explanation:

abs(4x-3)=7

4x-3=7, 4x-3=-7

4x=7+3=10

x=10/4=5/2

----------------

4x=-7+3

4x=-4

x=-4/4=-1

Answer:

x = 2.5 or 5/2

Step-by-step explanation:

4x - 3 = 7

    +3   +3

4x = 10

divide by 4

x = 2.5, or 5/2

Answer:

C. d(t) = 2.37t; 14.22 ft

Step-by-step explanation:

2.37 per minute is multiplication so A and B are definitely wrong

Another way to check is 2.37*6=14.22 so the answer is C

Answer:

D. d(t) = 6t; 14.22 ft

Step-by-step explanation:

d(t)= 2.37t; 14.22 ft

d(t)= 2.37t; 14.22 ft

Answer:

a. f(t)=2.37t

b.  14.22 feet

Step-by-step explanation:

We are given that:

A snail travels at a rate of 2.37 feet per minute.

a. write a rule to describe a function.

Let t describe the time and f(t) be a function how far snail travels

then,     f(t)=2.37×t

where the unit of t is in minutes and that of f(t) is feet

b. how far will the snail travel in 6 minutes

we have to find f(t) at t=6

f(6)= 2.37×6

  = 14.22 feet

Hence, snail traveled 14.22 feet in 6 minutes

2.37/minute

14.22 feet in six minutes

Answer:

Rule for Distance is f(t) = 2.37t and distance covered in 6 minutes is 14.22 feet.

Step-by-step explanation:

Speed of Snail = 2.37 feet per minute

To write the rule we use relation of Speed, Distance and time

Distance = Speed × Time

So, Distance cover by snail in t minutes is given by f(t) = 2.37 × t

⇒ f(t) = 2.37t

Distance traveled by Snail in 6 minutes , f(6) = 2.37 × 6 = 14.22 feet

Therefore, Rule for Distance is f(t) = 2.37t and distance covered in 6 minutes is 14.22 feet.
