Find the simplified form of the expression. Give your answer in scientific notation.
(4 * 10^10)(9x10^-5)

Answer:

  2, 4, 6

Step-by-step explanation:

You want three consecutive even integers such that the sum of twice the first and three times the second is 4 more than twice the third.

Let x represent the middle integer. Then the first is (x-2) and the third is (x+2). The given relation is ...

  2(x -2) + 3x = 2(x +2) +4

Simplifying the equation gives ...

  2x -4 +3x = 2x +4 +4

  5x -4 = 2x +8 . . . . . . . collect terms

  3x = 12 . . . . . . . . . . . add 4-2x

  x = 4 . . . . . . the middle integer

The integers are 2, 4, 6.

Additional comment

It often simplifies the equation if the variable is used to represent the middle of the consecutive integers in problems like this. In this particular problem, there is not a great advantage.

Answer:

-4/√5

Step-by-step explanation:

when f(x) = 0.

we can set the function equal to 0 and solve for x:

√5x + 4 = 0

√5x = -4

x = -4/√5

So the zero of the function is x = -4/√5

Answer:

K

Step-by-step explanation:

K represents negative 1 ⅓.

to find the opposite of a number you must look to see if its negative. if its negative then its opposite would be a positive. If its a positive then its opposite would be a negative. Opposites are always the number in opposite signs like 7 and -7.

I found K to be 1⅓ because there are 2 spaces in between numbers so it would be ¹ ⅓ ⅔ 1. so I went to the number 1 and went one space back/where K because I know it would be 1 ⅓

The correct option is E. the roots of the auxiliary equation are √6 and -√6.

Differential equations are defined as the equations in which consist of one or more terms which consist of the a dependent variable and it's derivatives with respect to the independent variable.

Given differential equation,

[tex]\frac{d^{2} y}{dx^{2} }[/tex] - 6y = 0

This can be also written as,

y'' - 6y = 0, where y'' indicates the second derivative of y.

Auxiliary equation is the polynomial equation which is found by replacing the right member of a standard differential equation by zero.

To find the roots of auxiliary equation can be found by,

Let m = y', then m² = y''

m² - 6 = 0

m² = 6

m = ± √6

So the roots are √6 and -√6.

Hence the roots of the auxiliary equation of the given differential equation are √6 and -√6.

Answer: The answer provided is based on the following calculation:

To make a 75% syrup, Ella should add enough water to the sugar to create a solution that is 25% sugar and 75% water.

To calculate how much water to add, you can use the formula: (desired % of sugar) / (100 - desired % of sugar) * (amount of sugar).

In this case, it would be: (0.75) / (100 - 0.75) * (0.5 lb) = 0.67 lb of water.

To calculate the total amount of syrup, you add the amount of sugar and the amount of water: 0.5 lb + 0.67 lb = 1.17 lb.

So Ella should add 0.67 lb of water to make a 75% syrup and will have a total of 1.17 lb syrup.

Step-by-step explanation:

Answer:

for the 75% syrup: 0.167lbs

For the 1.5% syrup: 32.83 lbs

Since the centre of the circle is (-2;-7), we equate the variable to its coordinate:

X=-2

Y=-7

now we bring the coordinate over to the left side which changes its sign.

X+2=0

Y+7=0

That explains the :

(X+2)^2 +(Y+7)^2

Now for the R.

its given that the radius is 6 and since the standard form for the equation of a circle requires r^2.

we simply square 6.

6^2=36.

Answer: (x+2)^2+(y+7)^2=36

Step-by-step explanation:

To write an equation for a circle when you know

the radius is R

the center is at (A, B), remember that the standard form of the equation of the circle is:

Just plug those values into this equation:

(x-A)^2+(y-B)^2=R^2

You will end up with this equation

The triangle has length of the side h is equal to 97.1 inches approximately to the nearest tenth, using the sine rule.

The sine rule is a relationship between the size of an angle in a triangle and the opposing side.

For the triangle ΔGHI, by sine rule;

g/sinG = h/sinH = i/sinI

We first derive the angle G as follows:

151° + 7° + G = 180° {sum of interior angles of a triangle}

G = 180° - 158

G = 22°

Hence by sine rule;

75/sin22° = h/sin151°

h = (75 × sin151°)/sin22° {cross multiplication}

h = 97.1

Therefore, by application of the sine rule we have the length of the side h = 97.1 inches approximately to the nearest tenth

Thus;

When m = 0, we have;

2(0) + 4s = 16

4s = 16

divide both sides by 4 to get;

s = 4

When s = 3;

2m + 4(3) = 16

P(A|B) read as the probability of the event A given the event B is equal to 0.5000 rounded up to four decimal place.

Conditional probability is known as the possibility of an event or outcome happening, based on the existence of a previous event or outcome. The conditional probability P(A|B) occur only in the case of dependent events. It gives the conditional probability of A given that B has occurred.

P(A|B) = P(A∩B) / P(B)

P(A∩B) = Probability of happening of both A and B

When a die is rolled, the sample space = {1, 2, 3, 4, 5, 6}.

A is the event the blue die shows a number greater than 2, So;

A = {3, 4, 5, 6}

B is the event the red die shows a number less than 5. So;

B = {1, 2, 3, 4}.

Then A∩B = {3, 4}

P(A∩B) = 2/6 = 1/3

P(B) = 4/6 = 2/3

P(A|B) = 1/3 ÷ 2/3

P(A|B) = 1/3 × 3/2 {changing division to multiplication}

P(A|B) = 1/2

Therefore, the conditional probability of the event A given the event B denoted by P(A|B) is equal to 1/2 or 0.5000 to four decimal place.

End Balance: $3,839.25 + $2,579.20 - $2,190.05 = $5,735.15, so the reconciled balance of $5,735.15.

This theory is used to compare the bank statements to the check register in order to properly reconcile the two balances.

The theory used in this question is the bank reconciliation theory.

Step 1: Begin by looking at the two balances - the check register balance and the bank statement balance.

In this case, the check register balance is $3,839.25 and the bank statement balance is $3,450.10.

Step 2: Add up all of the deposits that are not reported on the bank statement. In this case, the deposits are $2,000, $135.67, $254.77, and $188.76.

Step 3: Subtract all of the checks that are not reported on the bank statement. In this case, the checks are $567.89, $23.83, $598.33, and $1,000.

Step 4: Add the deposits and subtract the checks from the check register balance.

In this case, the check register balance ($3,839.25) plus the deposits ($2,579.20) minus the checks ($2,190.05) gives a reconciled balance of $5,735.15.

Answer: If the model kit for the Dornier Do17 airplane has a wingspan of 10 inches and the scale of the kit is 1 inch to 72 inches. This means that for every inch on the model, the equivalent measurement on the actual Dornier Do17 airplane is 72 inches.

We know that the wingspan of the model is 10 inches and we want to find the actual wingspan of the airplane so we'll use the scale factor of 1:72

To find the actual wingspan, we'll multiply the wingspan of the model by the scale factor.

10 inches * 72 inches/1 inch = 720 inches

Therefore, the actual wingspan of the Dornier Do17 airplane is 720 inches or 60 feet.

What are exponential functions?

An exponential function is a Mathematical function in the form f (x) = a^x, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.

Now,

Given points for exponential function are (2, –50), (4, –1250).

and exponential function is y=ab^x

To find a and b put points in the function

-50=ab^2 -->1

-1250=ab^4 --->2

From equation 1

a=-50/b^2

An triangle is a polygon since it has four or more parts. It is a simple geometric shape. A square having angles A, B, and C is referred to as a triangle ABC. When the sides are not collinear, Euclidean geometry generates a single plane and square. If a triangle has three sides and three corners, it is a polygon. The corners of a triangle are where its three sides meet. The sum of the angles in a triangle is 180 degrees.
