Answer:

B=10^18

Step-by-step explanation:

A=10*log(B)

180=10*log(B)

18=log(B)

10^18=10^log(B)

10^18=B

Therefore, B=10^18

Answer:

A' = 3A

Step-by-step explanation:

The area of a triangle is given by :

[tex]A=\dfrac{1}{2}\times b\times h[/tex]

Where

b is base and h is height

If height is tripled, h' = 3h

New area,

[tex]A'=\dfrac{1}{2}\times b\times h'\\\\=\dfrac{1}{2}\times b\times 3h\\\\=3\times \dfrac{1}{2}\times b\times h\\\\=3A[/tex]

So, the new area becomes 3 times the initial area.

Answer:

55.4 ft/s

Step-by-step explanation:

The easiest way to do this is to plug it into a calculator. The problem tells us that x is an object that has fallen a certain amount of feet. Then, the problem gives us that the object has fallen 48 feet. We can now plug 48 in for x and you get 55.4

Answer:

Y=-2/3+4

Step-by-step explanation:

The slope of the equation can be solved with

2-4/3-0 y2-y1 divide by x2-x1 which gives 3/2 and the y intercept the point at which the slope hits the y intercept which is 4. Also the slope is negative as it’s pointed downwards.

Getting the slope:

m=[tex](y_1 - y_2 )/(x_1 - x_2)[/tex]

Using this formula, the slope is calculated to be -2/3

To find intercept, plug in a point value into equation and solve.

Intercept = 4

Total equation: y=-2/3x + 4

Answer:

g(x) = e^(x + 2) + 2

Step-by-step explanation:

First, let's describe the shifts.

Vertical shift.

For a function f(x), a vertical shift of N units is written as:

g(x) = f(x) + N

If N is positive, then the shift is upwards.

If N is negative, then the shift is downwards.

Horizontal shift.

For a function f(x), a horizontal shift of N units is written as:

g(x) = f(x - N)

If N is positive, the translation is to the right

If N is negative, the translation is to the left.

Now let's solve the question.

f(x) = e^x

First, we have a vertical shift up of 2 units, then:

g(x) = f(x) + 2

Now we have a shift to the left of 2 units:

g(x) = f(x - (-2)) + 2

g(x) = f(x + 2) + 2

Then:

g(x) = e^(x + 2) + 2

Step-by-step explanation:

1.95 is the correct answer

Answer:

20 ft

Step-by-step explanation:

Area of a rectangle = length x width

600 ft^2 = 30 ft x length

length = 600 / 30

= 20 ft

Answer:

18 ÷ (-2) = -9

Step-by-step explanation:

18 ÷ (-2) = -9 is the least possible quotient.

To meet the requirement, we should divide the biggest positive number by smallest negative number

Answer: [tex]770,000[/tex]

Step-by-step explanation:

Given

The present population of bacteria is [tex]1,92,500[/tex]

It doubles in every 238 minutes

So, after 238 minutes it is

[tex]\Rightarrow 192,500\times 2=385000[/tex]

After another 238 minutes i.e. 476 minutes from starting, they becomes

[tex]\Rightarrow 385000\times 2=770,000[/tex]

Answer:

solution given:

principal [P]=$850

time[T]=8years

rate[R]=8%

now

simple interest [S.I.]=[tex] \frac{P×T×R}{100}[/tex] =$ [tex] \frac{850×8×8}{100}[/tex] =$544

so

Total balance=S.I.+P=$544+$850=$1394.

option b.$1,394.00 is your answer

Answer:

x = 70°, y = 110° , z = 85°

Step-by-step explanation:

∠ BEA and ∠ CDA are corresponding angles and congruent , then

x = 70°

x and y are adjacent angles and sum to 180°

x + y = 180°

70° + y = 180° ( subtract 70° from both sides )

y = 110°

∠ ABE and ∠ ACD are corresponding angles and congruent , then

z = 85°

Answer:

21b+x

Step-by-step explanation:

Answer:21b+x

Step-by-step explanation:

i got u

Answer:

When 2 lines are parallel, the sum of interior corresponding angles = 180

120 + b = 180

b = 180 - 120 = 60

a + 30 = 180

a = 180 - 30 = 150

Answer:

y = 9x - 49

Step-by-step explanation:

y2 - y1/ x2 - x1

14 - 5/ 7 - 6

9/1

= 9

y = 9x + b

5 = 9(6) + b

5 = 54 + b

-49 = b

Answer: 20% of 11 is 2.2

Step-by-step explanation:

Answer:

55

Step-by-step explanation:

To solve this set up a proportion. This proportion should be in part/whole form. This means to divide the part (aka 11) by the whole (aka the variable), additionally, 20% can be made into a fraction by dividing it by 100. So the proportion is [tex]\frac{20}{100} =\frac{11}{x}[/tex]. Then, cross multiply. Once this is done the new equation is [tex]20x=1100[/tex]. Next, divide both sides by 20. This gives you [tex]x=55[/tex], therefore 11 is 20% of 55.

Answer:

(x - 3)(x - 12)

Step-by-step explanation:

Assuming you require to factor the expression

x² - 15x + 36

Consider the factors of the constant term (+ 36) which sum to give the coefficient of the x- term (- 15)

The factors are - 3 and - 12, since

- 3 × - 12 = + 36 and - 3 - 12 = - 15 , then

x² - 15x + 36 = (x - 3)(x - 12) ← in factored form
