whats the gcf of 11 and 19?​

We get the value of h(1) × g(1) as - 14 for the functions g (x) = x - 3 and h (x) = x² + 6.

We are given the two functions as:

g (x) = x - 3 and h (x) = x² + 6

Now, we will first find h (1)

h (1) = (1)² + 6

h(1) = 1 + 6

Add them, we get:

h (1) = 7

Now, we will find g (1):

g (1) = 1 - 3

g (1) = - 2

Now we will find the expression  h(1) × g(1):

h(1) × g(1) = 7 × ( - 2 )

h(1) × g(1) = - 14

Therefore, we get the value of h(1) × g(1) as - 14 for the functions g (x) = x - 3 and h (x) = x² + 6.

What is 87.65 decimal in octal? 87.65 from decimal to octal is 127.5146314631. Here we show you how to write 87.6510 in octal and how to convert 87.65 from base-10 to base-8.

To convert decimal number 87.65, we convert its integer and fraction part individually and then add them to get the equivalent octal number, as below:

To convert integer 87 to octal, follow these steps:

Divide 87 by 8 keeping notice of the quotient and the remainder. Continue dividing the quotient by 2 until you get a quotient of zero.

Then just write out the remainders in the reverse order to get the equivalent octal number.

87 / 8 = 10 with remainder 7

10 / 8 = 1 with remainder 2

1 / 8 = 0 with remainder 1

Answer:

Option 2

Step-by-step explanation:

The distances will be the same because the bisector will create congruent triangles, and the desired equalities follow from CPCTC and the definition of congruency.

Applying the negative exponent rule, the value of 9^-1/2 is calculated as: 1/3.

If a number has a negative exponent, i.e. a^-1/2, it can be rewritten and expressed as:

a^-1/2 = 1/a^½

1/a^½ can also be rewritten or expressed as:

1/a^½ = 1/√a

Thus, we would apply the negative exponent rule to find the value of the expression, 9^-1/2 as explained below:

9^-1/2 = 1/9^½

Rewrite 1/9^½ as 1/√a

1/9^½ = 1/√9

Take the square root of 9

1/√9 = 1/3

This implies that, the value of the expression, 9^-1/2 is 1/3.

In conclusion, applying the negative exponent rule, the value of 9^-1/2 is determined as: 1/3.

The inverse of the expression y = 5 · (x - 6)² - 5 is x = √[(y + 5) / 5] + 6. (Correct choice: D)

According to the statement we have a function of the form y = f(x) and we need to find its inverse, that is, finding the equation of x in terms of y. This can be done by using algebra properties:

Answer: 8,938 [tex]\frac{8}{9}[/tex] or 8,938.8889 meters per second

Step-by-step explanation:

     To solve this problem, we will use a process called dimensional analysis (that you have probably done many times without realizing it).

     What is dimensional analysis? Let's say you know there are 12 inches in a foot, and you want to know how many inches are in 2 feet. 12 * 2 = 24 inches in a foot, that's dimensional analysis!

     Here is the process you would take to solve your problem:

➜ If we have the units [tex]\frac{hour}{hour}[/tex], they "cancel" out to become one. This way, we make sure we end up with the correct units, [tex]\frac{meters}{second}[/tex].

➜ We take units we know, such as 3,600 seconds in an hour, and multiply them by the original value until we end up with the measurement we want.

[tex]\displaystyle 20,000\; \frac{miles}{hour}*\frac{1 \;hour}{3,600\; seconds} *\frac{1,609\;meters}{1\;mile}=\frac{20,000*1*1,609\;meters}{3,600\;seconds} =\frac{32,180,000\;meters}{3,600\;seconds} = 8,938.89\; \frac{meters}{second}[/tex]

     In other words;

           8,938.89 meters per second

Answer:

y = -2

Step-by-step explanation:

Given equation:

[tex]3(-4y-5)=8y+25[/tex]

Distribute:

[tex]\implies 3 \cdot -4y - 3 \cdot 5=8y+25[/tex]

[tex]\implies -12y - 15=8y+25[/tex]

Add 15 to both sides:

[tex]\implies -12y - 15+15=8y+25+15[/tex]

[tex]\implies -12y =8y+40[/tex]

Subtract 8y from both sides:

[tex]\implies -12y-8y =8y+40-8y[/tex]

[tex]\implies -20y =40[/tex]

Divide both sides by -20:

[tex]\implies \dfrac{-20y}{-20} =\dfrac{40}{-20}[/tex]

[tex]\implies y =-2[/tex]

Now we have to,

→ solve for the required value of y.

Let's solve the problem,

→ 3(-4y - 5) = 8y + 25

→ -12y - 15 = 8y + 25

→ -12y - 8y = 25 + 15

→ -20y = 40

→ y = -40/20

→ [ y = -2 ]

Hence, the value of y is -2.

The the distance between the school and Nokesville be on the map is 0.7 inches.

What is scaling ?

It is the technique to resize drawing with comparing to actual size of object which uses proportion or ratio. For example, Mapping of earth, drawing prototype of automobiles.

It is given that :

The distance between the school and Target is 4.2 miles and on a map the ratio is 0.5 inches is equal to 3 miles that is :

3 miles = 0.5 inches on map

Now to find the distance between the school and Nokesville be on the map we first find for 1 miles on the map and then multiply it by 4.2 miles :

3 miles = 0.5 inches on map

1  miles = 0.5/3 inches on map

4.2 miles = (0.5/3) x 4.2 inches on map

4.2 miles = 0.7 inches inches on map

Therefore, the the distance between the school and Nokesville be on the map is 0.7 inches.

The answer to the present question is:5x² + 13x - 6 = (5x - 2) (x + 3)

For a polynomial, ax² + bx + c, we want to separate the center term because the sum of these two numbers, whose sum is adequate to the merchandise of the opposite two numbers.

So, here, we'd like to rewrite 13 because the sum of two numbers, whose product is adequate to the opposite two numbers, i.e., 5*(-6) = -30

So, to separate 13, two numbers used here will be: 1 5 and -2, because after we will add 15 and -2 we are going to get 13 and that we will multiply them, then we are going to get

-30.5x² + 13x -6 = 5x² + 15x - 2x - 6

                           = 5x(x + 3) - 2(x + 3)

                             = (5x - 2) (x + 3)

Therefore,  5x² + 13x - 6 = (5x - 2) (x + 3)

The value of the expression √75 + √125 is 5 (√3 + √5 ).

A number is a fundamental mathematical unit. For counting, measuring, and comparing quantities, we utilize numbers. A set of symbols, or numerals, used to represent numbers is known as a number system.

A square root is a factor of a number that yields the original number when multiplied by itself.

Consider the expression √75 + √125,

Let's assume x = √75 + √125

Now,

75 = 5 × 15 = 5 × 3 × 5

125 = 5 × 25 = 5 × 5 × 5

Therefore,

x = √75 + √125

x = √ [ 5 × 3 × 5] + √ [ 5 × 5 × 5 ]

x = 5√3 + 5√5

x = 5 × [ √3 + √5 ]

x = 5 × [ 1.73 + 2.24 ]

x = 5 × 3.97

x = 19.85

√75 + √125 = 19.85

Hence, the value of √75 + √125 is equal to 19.85.

Answer:

(0, - 9 )

Step-by-step explanation:

x = 2y + 18 → (1)

5x = - 3y - 27 → (2)

substitute x = 2y + 18 into (2)

5(2y + 18) = - 3y - 27

10y + 90 = - 3y - 27 ( add 3y to both sides )

13y + 90 = - 27 ( subtract 90 from both sides )

13y = - 117 ( divide both sides by 13 )

y = - 9

substitute y = - 9 into (1)

x = 2(- 9) + 18 = - 18 + 18 = 0
