The coordinates of H are (-9,-1) when H is on FG and divides it such that  FH:GH is 1:2.

It is given that  F(–8,3) and G(–2,–9) and ratio of  FH:GH is 1:2.

The diagram of this question is given below.

Let  coordinates of H be ( x , y) .

By using sections formula , we get

(x , y) = ( 1(-2) + 2(-8) / 1+2 , 1(-9) +2(3) / 1+2 )

(x , y) =  ( -2 -16 / 1 +2 , -9 +6 / 1 +2 )

Answer: 17/18=34/36

11/12=33/36

Step-by-step explanation:

17/18 and 11/12

First find the LCM, least common multiple, of the denominators 18 and 12.

In order to do that, list the factors of 18 and 12 and find the least common factors of them excluding 1.

18: 1, 2, 3, 6, 9, 18

12: 1, 2, 3, 4, 6, 12

Notice any common small factors? Yes they are 2 and 3. Now, multiply them with 18 and 12.

18*2=36

12*3=36

Hence, LCM is 36.

17/18=(17*2)/(18*2)=34/36

11/12=(11*3)/(12*3)=33/36

The Red Savina Habanero is 6. 13 times hotter than the Thai Pepper. Option A

A ratio can be defined as the comparison of two or more numbers on the basis of their sizes in relation to each other;

Given that;

To determine the ratio, we have to divide Red Savina Habanero hotness rating by Thai Pepper hotness rating

This is represented as;

= 4.6 x 10^5 /  7.5 x 10^4

= 6. 13 times

The Red Savina Habanero is 6. 13 times hotter

Thus, the Red Savina Habanero is 6. 13 times hotter than the Thai Pepper. Option A

By taking the quotient between the ratings, we can see that  Red Savina Habanero is 6.13 times hotter than the Thai Pepper.

We know that the Thai Pepper has a hotness rating of 7.5*10⁴, while the Red Savina Habanero has a hotness rating of 4.6*10⁵.

We want to see how many times hotter is the Red Savina Habanero than the Thai Pepper, to find that we need to take the quotient between the rating for the Habanero and the rating for the Pepper.

It gives:

Q = (4.6*10⁵)/(7.5*10⁴)

This can be rewritten as:

Q = (4.6/7.5)*(10⁵/10⁴)

   =0.613*(10 ⁵⁻⁴) = 0.613*10

Now, we want to write this in scientific notation, so we need to have a single digit different than zero in the left side of the decimal point.

Then we can rewrite:

0.613*10 = 6.13*10⁰ = 6.13

We conclude that the Red Savina Habanero is 6.13 times hotter than the Thai Pepper.

Step-by-step explanation:

x+1 ≤-3 or-4x<-8

First solve the inequality on the left

x+1 ≤-3

Subtract 1 from each side

x+1-1 ≤-3-1

x ≤-4

Then solve the inequality on the right

-4x<-8

Divide each side by -4, remembering to flip the inequality

-4x/4 > -8/-4

x > 2

Put them back together

The value of x that cannot be evaluated in the function F(x) is 3

The domain of the function is the set of input values of the graph

The range of a function is the set of output values of the graph.

This in other words mean the range of a function is the set of y values of the graph.

The function is given as

f(x) = (x + 13)/(x - 3)

Set the denominator of the function to 0

So, we have

x - 3 = 0

Evaluate the equation

x =3

This means that x =3 is not in the domain of the function

Hence, the value of x that cannot be evaluated in the function F(x) is 3

The probability that both the balls are black is  [tex]\frac{1}{9} \\[/tex] .

Probability is the section of mathematics which deals with the likelihood of an event happening.

The value of probability is a fraction which always lies between 0 and 1. it is defined as the ratio of the favorable outcomes of an event to the total outcome of an event.

Given the bag has 10 white balls and 5 black balls. Therefore the total number of balls in the bag is 15 .

Hence the sample space is 15 .

The balls are drawn with replacement. Therefore for the first ball pick:

Number of favorable outcomes = 5

Total number of outcomes = 15

Probability = favorable outcome ÷ total outcome

Therefore  [tex]P_1=\frac{5}{15}=\frac{1}{3}[/tex]

Now the ball is placed back and the second ball is picked.

Number of favorable outcomes = 5

Total number of outcomes = 15

Probability = favorable outcome ÷ total outcome

Therefore  [tex]P_2=\frac{5}{15}=\frac{1}{3}[/tex]

Now the total probability that both the balls are black is :

P = P₁×P₂

[tex]P=\frac{1}{3}\times \frac{1}{3}\\\\P=\frac{1}{9}[/tex]

Hence the probability of picking two black balls is  [tex]\frac{1}{9} \\[/tex]  .

let me give you a mouthful of something

the domain of f(x) is the range of its inverse, or namely the domain of f(x) is the same set as the range of f⁻¹(x), so for any (a , b) pair on the domain of f(x), there's a (b , a) on the range of f⁻¹(x).

now, that's a bit of of a mumble, but in short it means, if f(x) has a point of (3 , 5), then the graph of f⁻¹(x) has a point which is the same pair but flipped sideways, namely (5 , 3).

that's pretty much true for any function that has an inverse.

3200 meters by using the units of conversion will be equal to 3.2 km.

We are given:

3200 meters.

We know that the unit of conversion for the meters and kilometers is given by:

1 km = 1000 m

1 m = 1 / 1000 km

For 3200 m, we will use the operation of multiplication.

So, we get that:

3200 m = 1 / 1000 × 3200 km

3200 m = 3.2 km.

The solutions of the system of equations are:

x = -2, y = 4, z = -2

Here we have the system of equations:

4x - y - 2z = -8

-2x + 4z = -4

x + 2y = 6

To eliminate one variable, we can add the second equation and two times the third equation, we will get:

(-2x + 4z) + 2*(x + 2y) = -4 + 2*6

Now we can simplify that so we get:

4z + 4y = -4 + 12

4*(z + y) = 8

z + y = 8/4  =2

z + y = 2

With that we can write z in terms of y.

z = 2 - y

And with the third equation we can write x in terms of y.

x = 6 - 2y

Replacing that in the first equation we get:

4*(6 - 2y) - y - 2*(2 - y) = -8

Now we can solve this for y.

24 - 8y - y +2y - 4 = -8

20 - 11y = -8

-7y = -28

y = 28/7  = 4

Now that we know the value of y we can find the values of x and z.

x = 6 - 2y = 6 - 2*4 = -2

z = 2 - y = 2 - 4 = -2

The solutions of the system of equations are:

x = -2, y = 4, z = -2

Mean, median, and mode are measures of central tendency. Mean is the average of a set of numbers. Median is the number that is at the center of a dataset when the dataset is arranged in ascending or descending order. Mode is the number that occurs most frequently in a dataset.

Mean = sum of numbers / total number

(11.3 + 9.9 + 9.6 + 11.5 +9.6 + 11.2 + 10.6) / 6
