3. Which point lies inside the circle with equation (x - 2)2 + (y + 3)2 = 4?
(2,-5)
(2,0)
(2,-4)
(0, -3)

Answers

Answer 1

Answer:

C (2,-4)

Step-by-step explanation:

You could graph the circle and then graph the points and see...

Or you could them in and see which point makes the left hand less than 4?

So if you wanted to draw it is a circle with center (2,-3) and radius 2.

If you want to do it the other way:

Plug in time!

(2,-5)?

(2-2)^2+(-5+3)^2

0^2+(-2)^2

0+4=4 so not this one

(2,-4)?

(2-2)^2+(-4+3)^2

0+1

1<4  so this one  (you can also see this in the drawing:

3. Which Point Lies Inside The Circle With Equation (x - 2)2 + (y + 3)2 = 4?(2,-5)(2,0)(2,-4)(0, -3)

the number of pieces of popcorn in a large movie theater popcorn bucket is normally distributed, with a mean of 1610 and a standard deviation of 10. Approximately what percentage of buckets contain between 1600 and 1620 pieces of popcorn?

A. approximately 68%
B. approximately 75%
C. approximately 95%
D. approximately 99.7%

Answers

Answer:

A. Approximately 68%

Step-by-step explanation:

Number of pieces of popcorn in a bucket is normally distributed.

Mean = μ = 1610

Standard deviation = б = 10

We know that in normal distribution, approximately 34% of bags will fall with in one standard deviation on one side. On both sides within the range of 1 standard deviation, 34 + 34 = 68 % of bags will fall.

A table of normal distribution about mean is attached for better understanding.

Our range is:

1600 to 1620

1610 - 10 to 1610 + 10

μ ± б

mean ± 1 standard deviation

Our range is within 1 standard deviation. Hence, Approximately 68% of buckets contain between 1600 and 1620 pieces of popcorn.

which graph or graphs appear to show a sinusoid ?

Answers

Answer:

D

Step-by-step explanation:

Sinusoid graphs look like regular waves.

It is obvious that only I and III look like waves.

II is known as a stepwise function.

Answer:

Option: D is the correct answer.

             D.   I and III only

Step-by-step explanation:The graph of a sinusoidal function is a smooth periodic graph.The graph is continuous all over the x-axis and also it repeats itself after every fixed interval.

From the graph that is provided to us we observe that the graph I is a sinusoidal graph since it is similar to a graph of sine graph.

Also, the graph II is not a continuous graph and hence it can't be a graph of sinusoidal graph.

Also, graph III is similar to a graph of sine function and hence it represent a graph of a sinusoidal graph.

What values are excluded from the domain and range of the function f(x)= x+3/2x+5?

Answers

Answer:

B. Domain: -5/2

Range: 1/2

Step-by-step explanation:

If you plug -5/2 for x, it becomes no solution due to the zero in the denominator.

If you plug 1/2 for y and let your calculator do its thing, it becomes no solution.

Because these values cannot be solved for in the equation, they are excluded from the domain and range.

Edit: I got it correct on the Unit Review on edge.

The domain and range values that are excluded from the function given as  f ( x ) = ( x + 3 ) / ( 2x + 5 ) are x = -5/2 and y = 0

What are domain and range?

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

The function f(x) = (x + 3)/(2x + 5) has certain values that are excluded from its domain and range.

The function f(x) is defined for all real numbers except for the values of x that make the denominator (2x + 5) equal to zero.

Therefore, the values of x that are excluded from the domain of f(x) are those that satisfy the equation 2x + 5 = 0.

2x + 5 = 0

2x = -5

x = -5/2

The range of f(x) is all real numbers except for zero (0), because it is never equal to zero.

Hence , the values excluded from the domain of f(x) are x = -5/2 and the values excluded from the range of f(x) are y = 0

A car travels 85 kilometers per hour. What is the equivalent speed in meters per hour?

Answers

The equivalent speed in meters per hour is 85000 m/hr.

What is speed?

Speed exists as a scalar quantity that describes how fast an object is moving, regardless of its direction.

Speed exists as the time rate at which an object exists moving along a path, while velocity exists as the rate and direction of an object's movement. Put another way, speed exists as a scalar value, while velocity is a vector.

Here given that,

A car travels 85 kilometers per hour.

Using, the general conversion method.

1 km = 1000 m

= ( 85 km/hr ) (1000 m/1km)

The unit km cancels = 85000 m/hr

Hence, 85000 m/hr is the equivalent speed in meters per hour.

85,000 meters per hour.

If a car travels 85 kilometers per hour, to find the equivalent speed in meters per hour, we need to convert kilometers into meters. Since 1 kilometer is equal to 1,000 meters, we multiply the speed in kilometers by 1,000 to get the speed in meters.

So, the car's speed in meters per hour would be:

85 km/h  × 1,000 m/km = 85,000 meters per hour.

This conversion is straightforward and is based on the relationship that 1 km = 1,000 m.

Answers

Answer:

Step-by-step explanation:

Answer:

The actual distance between the two cities is 28 kilometers

Step-by-step explanation:

A map has a scale of 3.5 inches = 20 kilometers

Distance between two cities on the map = 4.9 inches

We can use the unitary method in this question to get the actual distance between two cities

∵ 3.5 inches on the map = 20 kilometers

∴ 1 inch distance on the map = [tex]\frac{20}{3.5}[/tex] kilometers

∴ 4.9 inches on the map = [tex]\frac{20}{3.5}\times 4.9[/tex]

                                         = 28 kilometers

Therefore, the actual distance between the two cities is 28 kilometers.

plz Simplify using i. √-15√-4

Answers

Final answer:

The expression √-15√-4 is simplified to -2√15 using the imaginary unit i, where i represents the square root of -1. We do this by simplifying each square root with i and then multiplying the results together, remembering that i^2 equals -1.

Explanation:

To simplify the expression using i, where i is the imaginary unit we define as the square root of -1, we have √-15√-4. We can start by simplifying each square root separately using i:

√-15 = √(15 × -1) = √15 × √i = √15i

√-4 = √(4 × -1) = √4 × √i = 2i

Now, you simply multiply the two results together:

√15i × 2i = (√15 × 2) × (i × i) = 2√15 × i²

Since equals -1, our expression simplifies to:

2√15 × -1 = -2√15

Therefore, the simplified form of the expression √-15√-4 using i is -2√15.

Which number can each term of the equation be multiplied by to eliminate the fractions before solving? 6 – x + = x + 5 2 3 6 12

Answers

Answer:its 12

Step-by-step explanation:

The number can each term of the equation be multiplied by to eliminate the fractions before solving is 12, the correct option is D.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

Equation 6 – x + = x + 5

Now,

the least common multiple of 2 and 3, which are the denominators of the fractions in the equation. Multiplying each term by 12 will clear the fractions and result in an equivalent equation without fractions. For example: 12(6 - x + ) = 12(x + 5) 2 3 Simplifying, we get: 72 - 12x + 4 = 12x + 60. This is an equation without fractions that can be solved for x.

Therefore, by the given equation the answer will be 12.
