Answer:

A) Ni Hua visited 12 islands and 7 peninsulas.

Step-by-step explanation:

If all visits had been to islands, Hua would have skydived 19·2 = 38 times. He actually skydived 45-38 = 7 times more than that. Each peninsula that replaces an island adds 1 skydive to his total, so he must have visited 7 peninsulas.

Hua visited 7 peninsulas and 12 islands.

The formula for area of a triangle is: 1/2 x base x height.

You are given the height of 4 and the area of 4.

Replace those in the formula and solve for x ( base)

4 = 1/2 x base x 4

Divide both sides by 4:

1 = 1/2 x base

Multiply both sides by 2:

2 = base

x = 2

Answer:

2=X

Answer:

For any question like this you take the number of ways an event can happen (odd number) and divide by the total number of possibilities (sides of a die). If you assume a six sided die there are 3 odd numbers, 1,3, 5. And 6 total sides, so 3/6 = 1/2 or 50%.

Step-by-step explanation:

Final answer:

The probability of rolling an odd number and then a number greater than 5 on a six-sided die in sequence is calculated by multiplying the two independent probabilities, resulting in a combined probability of 1/12.

Explanation:

The student wants to know the probability of landing on an odd number and then landing on a number greater than 5 when rolling a six-sided die. To solve this problem, we need to consider the two separate events independently and then calculate the combined probability.

First, let's consider the probability of landing on an odd number. There are three odd numbers on a die: 1, 3, and 5. Since each outcome is equally likely, the probability is the number of favorable outcomes over the number of possible outcomes, which is P(odd number) = 3/6 = 1/2.

Next, we calculate the probability of landing on a number greater than 5, which is only one number, 6. So, P(number > 5) = 1/6.

To find the probability of both events happening in sequence, we multiply the two probabilities: P(odd number) * P(number > 5) = (1/2) * (1/6) = 1/12. Therefore, the probability of rolling an odd number and then a number greater than 5 is 1/12.

ANSWER

D. -3 and 4

EXPLANATION

The given quadratic trinomial is

[tex] {x}^{2} + x - 12[/tex]

To factor this we need to find two factors of -12 that sum up to 1, the coefficient of x.

We can see from the table that, when p=-3 and q=4, then p+q =1.

The trinomial can now be factored as:

[tex] {x}^{2} + x - 12 = (x - 3)(x + 4)[/tex]

x > 12

Answer for 2/3>8

Answer:

x within the domain (-∞,0) ∪ (0,1/12) ∪ (1/6,∞)

Step-by-step explanation:

Let's find the solution by modifying the conditions like this:

First condition:

2/3x > 8

Notice that x needs to be a positive number because if x is negative number the expression 2/3x is always negative, and the given condition will be false. Also, x can't be 0 because dividing by 0 is not allowed.

Multiplying the first condition in both sides by (3x/2) we obtain:

(2/3x)*(3x/2) > 8*(3x/2) equal to:

1 > 12x, which dividing by 12 in both sides is:

1/12 > x, which means a domain: (0,1/12)

Second condition:

2/3x < 4

Notice that if x is negative, the expression (2/3x) is always negative, so the second condition will be always true, so negative numbers are not a problem for this conditions.

Let's find the highest positive number which allows the second condition to be a true statement.

Multiplying the second condition in both sides by (3x/2) we obtain:

(2/3x)*(3x/2) < 4*(3x/2) equal to:

1 < 6x, which dividing by 6 in both sides is:

1/6 < x which means a domain: (-∞,0) ∪ (1/6,∞), notice that 0 is not in the domain because dividing by 0 is not allowed, but also as mentioned before negative numbers makes the statement true.

Notice that the problem uses the word OR (condition one or condition two), which means that we need to create a domain for x which allows that always at least one condition is true.

Adding the x domains for the two conditions we obtain:

(-∞,0) ∪ (0,1/12) ∪ (1/6,∞); notice that all the boundary numbers are not included.

In conclusion, the statement 2/3x>8 or 2/3x<4 is true for x within the domain (-∞,0) ∪ (0,1/12) ∪ (1/6,∞).

Answer:

12 5 dollar bills

20 50 dollar bills

Step-by-step explanation:

Let x = number of five dollar bills

Let y = number of fifty dollar bills

We have a total of 32 bills

x+y = 32

The total amount is 1060

5x+50y = 1060

We have 2 equations and 2 unknowns

x+y = 32

5x+50y = 1060

Multiply the first equation by -5 so we can eliminate x

-5x -5y = -5*32

-5x -5y =-160

Add this to the second equation

5x+50y = 1060

-5x -5y =-160

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

45 y    = 900

Divide each side by 45

45y/45 = 900/45

y = 20

There are 20 50 dollar bills

x+y = 32

x+20 = 32

Subtract 20 from each side

x+20-20 = 32-20

x = 12

There are 12 5 dollar bills

Let's solve your equation step-by-step.

2x3−5x2+3x+7=x−2

Step 1: Subtract x-2 from both sides.

2x3−5x2+3x+7−(x−2)=x−2−(x−2)

2x3−5x2+2x+9=0

Step 2: Factor left side of equation.

(x+1)(2x2−7x+9)=0

Step 3: Set factors equal to 0.

x+1=0 or 2x2−7x+9=0

x=−1

Answer:

x=−1

The given equation is rearranged into a polynomial equation, and can be solved using methods such as factoring, the quadratic formula, graphing, or completing the square.

To solve this question, you first need to set the equation in order. You should arrange it as a quadratic equation (ax²+bx+c = 0). Given equation is:

2x³ - 5x² + 3x + 7 = x-2

We need to simplify this equation by adding '2' on both sides and subtracting 'x' from both sides:

2x³ - x - 5x² + 3x + 1 = 0

Now, it has been transformed into a polynomial equation with the variable x. Solving this kind of equation requires methods such as factoring, quadratic formula, graphing or completing the square.

ANSWER

B. Domain is (-∞,∞) and Range is (-∞,∞).

The given function is

[tex]f(x) = \sqrt[3]{x - 6} + 5[/tex]

This is function is obtained by shifting the base cubic root function 6 units to the right and 5 units up.

This function is defined for all real values of x.

Therefore the domain is all real numbers.

The range is all real numbers.

The domain for this function becomes the range for the inverse function and the range becomes the domain.

Hence the domain is (-∞,∞) and the range is (-∞,∞).

Step-by-step explanation:

QUES 1)

Let x denote the gig of data used.

and y denote the monthly charge for use of data

We know that the equation of a line with given slope "m" and y-intercept "c" is given by:

       y=mx+c

Runfast--

The monthly charge is: $ 8

and the cost of per gig of data is: $ 8

Since, the cost per gig represent the slope and fixed monthly charge represent the y-intercept.

Hence, the equation that is given by this set of information is:

             [tex]y=8x+8---------(1)[/tex]

BA & D--

The monthly charge is: $ 15

and the cost of per gig of data is: $ 4

Hence, the equation that is given by this set of information is:

             [tex]y=4x+15-----------(2)[/tex]

QUES 2)

We will substitute the value of y from equation (1) in equation (2) as follows:

 8x+8=4x+15

i.e.  8x-4x=15-8

i.e.   4x=7

i.e.   x=7/4=1.75

and the value of y is:

y=8×1.75+8

i.e.    y=22

Hence, the cost of both the companies are equal when 1.75 gigs of data is used and the cost is: $ 22

( Since , the solution is: (1.75,22)  )
