Answer: y= -1x + 2

Step-by-step explanation:

The linear equation is y= mx + b

Y-intercept here is at (0,2), so b is 2

Let pick point (0,2) (2,0)

The slope is rise/run, and we see that the graph is going down by 2 and goes over by 2, so it is -2/2 = -1

So the equation is y=1x +2

Answer: 24 units.

Step-by-step explanation: To find the perimeter of the right triangle, you need to add up the lengths of all three sides of the triangle.

The right triangle shown has a vertex at (-4, 4), another vertex at (4, 4), and a third vertex at (4, -2). The length of the side between the first two vertices can be calculated using the distance formula:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

= sqrt((4 - (-4))^2 + (4 - 4)^2)

= sqrt(8^2 + 0)

= sqrt(64)

= 8

The length of the side between the second and third vertices can be calculated using the distance formula:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

= sqrt((4 - 4)^2 + (-2 - 4)^2)

= sqrt(0 + (-6)^2)

= sqrt(36)

= 6

The length of the hypotenuse of the right triangle can be calculated using the Pythagorean theorem:

c^2 = a^2 + b^2

c = sqrt(a^2 + b^2)

= sqrt(8^2 + 6^2)

= sqrt(64 + 36)

= sqrt(100)

= 10

To find the perimeter of the triangle, add up the lengths of all three sides: 8 + 6 + 10 = 24 units.

Therefore, the perimeter of the right triangle is 24 units.

The inference from given boxplot is : The visiting team had more variability in the number of shots taken.

In this question we have been given two boxplots.

For the boxplots that the coach made,

for the home team:

Whiskers range is:16 to 32

So, the minimum value = 16

the maximum value = 32

the box ranges from 20 to 23. A line divides the box at 22.

so, the first quartile = 20

the third quartile = 23

the Median = 22

interquartile range(IQR) = 23 - 20

                                      = 3

And for the visiting team

Whiskers range :14 to 32

This means, the minimum value is 14 and the maximum value = 32

As the box ranges from 16 to 24 and a line divides the box at 18,

the first quartile is 16, the third quartile = 24 and the median = 18

So, the interquartile range (IQR) = 24 - 16

                                                   = 8

From above data analysis the inference is that the visiting team had more variability in their shots, because their distribution has a higher interquartile range (8 > 3)

Answer:

  SL = 2.1 miles

Step-by-step explanation:

Given ∆LRS with RS extended to point T, and angles R = 35° and exterior angle LST = 70°, you want the measure of SL. You want to apply the process to finding distance to shore.

The exterior angle LST is the sum of interior angles SRL and SLR. In equation form, this is ...

  ∠LST = ∠SRL +∠SLR

  70° = 35° +∠SLR

  ∠SLR = 35°

The angles at either end of segment LR are both 35°, so the triangle is isosceles. That means sides SR and SL are congruent:

  SL = SR = 2.1 miles

The distance from the boat to the lighthouse has been found using an isosceles triangle. A similar method can be used to find the distance to shore. It requires the captain to be able to identify a point on shore, and measure the distance traveled parallel to the shore.

By using a 45° angle to start, and a 90° angle at the second measurement, the distance traveled between angle measurements will be exactly the (closest) distance to shore from the point of the second measurement.

Other angle measures can be used with trigonometric methods.

Answer:

85 cm^2

Step-by-step explanation:

The surface area of a square pyramid is given by the formula:

Surface area = base area + 4 * (base edge length * slant height) / 2

In this case, the base area is 25 cm^2, because the side length of the base is 5 cm. The base edge length is also 5 cm, because it is a square pyramid. Plugging these values into the formula above, we get:

Surface area = 25 cm^2 + 4 * (5 cm * 6 cm) / 2

= 25 cm^2 + 60 cm^2

= 85 cm^2

So the surface area of the square pyramid is 85 cm^2.

The probability that no digit appears more than twice is 0.648.

What is probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Here,

We will choose each digit of 5-digit numbers at random from digits 0,1,2,..,9.

We have to compute the probability that no digit appears more than twice.

So, we have to form a five-digit number say "abcde".

Now, for 'a' we have 10 choices.

For 'b' we have again 10 choices because a digit can appear at most two.

For 'c' we have 9 choices because the digit in 'a' can not be chosen as a digit can appear at most two.

For 'd' we have again 9 choices by a similar argument.

Finally, for 'e' we have 8 choices because the digit chosen previously can not be repeated more than twice.

The total number of such 5-digit numbers is = 10*10*9*9*8 = 64800.

Now, a total number of 5-digit numbers = 10*10*10*10*10 = 100000.

Hence, the probability that no digit appears more than twice is given by,

= 64800/ 100000

= 0.648

Hence, the probability that no digit appears more than twice is 0.648.

Answer: 38 nickels, 24 quarters

Step-by-step explanation:

x=number of quarters

y=number of nickels

x + y = 62

$0.25x + $0.05y = $7.90

solve for x in terms of y, then substitute into the 2nd equation:

x = 62-y

.25(62-y) + .05y = 7.90

15.5 - .25y + .05y = 7.90

15.5 - .20y = 7.90

-.20y = -7.6

y = -7.6/-.20

y = 38

now solve for x:

x  + 38 = 62

x = 62-38 = 24

x = 24

What is the system of linear equations?

A system of linear equations is a collection of two or more linear equations, and a solution to a system of linear equations consists of values of each of the unknown variables in the system that satisfies all of its equations or makes them true.

Let L be the number of lions, T be the number of tigers, and B be the number of bears. We can set up the following system of equations to represent the given information:

L + T + B = 40

L = T + 4

B = T - 3

We can solve this system of equations using substitution. Starting with the second equation, we can solve for T:

T = L - 4

Substituting this expression for T into the third equation, we get:

B = L - 4 - 3

B = L - 7

Substituting this expression for B into the first equation, we get:

L + L - 4 + L - 7 = 40

3L - 11 = 40

3L = 51

L = 17

Now that we know the number of lions, we can substitute this value back into the equation T = L - 4 to find the number of tigers:

T = 17 - 4

T = 13

Finally, we can substitute these values for L and T into the equation B = L - 7 to find the number of bears:

B = 17 - 7

B = 10

Hence, Ms. Caraballo saw 17 lions, 13 tigers, and 10 bears at the zoo.

When working with rational functions, your main concern to not divide by 0.  Dividing by 0 can't be done.

So, you need to look at the denominator of your fraction and figure out what values of g will make that denominator become 0.

Option #1 is to plug in each option from your list to see which ones make the denominator equal 0.  If that g-value makes the denominator equal zero, then it has be excluded.

Option #2 is to set the denominator equal to 0 and solve that equation:
    g^3 - 4g^2 - 12g = 0

To solve this, you could do it by factoring.

    g^3 - 4g^2 - 12g = 0     

     g ( g^2 - 4g -12) = 0

   g ( g - 6 ) ( g + 2) = 0

This splits into:
   g = 0, g = 6, g = -2

So those are the three values of g that you cannot use.

g ≠ 0; g ≠ 6, g ≠ –2
