Answer:

7 km

Step-by-step explanation:

If I subtracted 18km by 11km my answer would be 7km

Answer:

21.1 km

Step-by-step explanation:

The northeast line and the southeast line will make a right angle so use the Pythagorean Theorem: a^2 + b^2 = c^2 and calculate c.

18² + 11² = c²

324 + 121 = c²

445 = c²

c = 21.1 km

Answer:

Its C

Step-by-step explanation:

I already did the test, and got it right.

I guess the answer should be 177.8 cm.

The measurement of 5 feet 10 inches to centimeters​ is 175 centimeters.

Units of measurement are defines ad the definite magnitude of a physical quantity. It is used to find a number that shows the amount of something.

Here we have to convert the units of measurement feet and inches to centimeters.

We have,

1 foot = 12 inches and 1 inch = 2.5 centimeters

We have to change 5 feet 10 inches to centimeters​.

1 foot = 12 inches

⇒ 5 feet = 12 × 5 inches

              = 60 inches

So, 5 feet 10 inches = 60 inches + 10 inches

                                 = 70 inches

1 inch = 2.5 centimeters

70 inches = 70 × 2.5 centimeters

                 = 175 centimeters

Hence we got 5 feet 10 inches as 175 centimeters.

Answer:

The exponential funtion is "height(n) = 77*(0.9925)^n". After 15 years he is 68.7778 inches.

Step-by-step explanation:

Since Tom's initial height is 77 inches. After one year:

height(1) = 77*(1 - 0.0075) = 77*0.9925

After two years:

height(2) = height(1)*(0.9925) = 77*0.9925*(0.9925) = 77*(0.9925)²

After three years:

height(3) = height(2)*0.9925 = 77*(0.9925)²*0.9925 = 77*(0.9925)³

And so on, therefore the expression that represents his height is:

height(n) = 77*(0.9925)^n

Where n is the number of elapsed years. For 15 years we have:

height(15) = 77*(0.9925)^(15) = 68.7778 inches

The exponential funtion is "height(n) = 77*(0.9925)^n". After 15 years he is 68.7778 inches.

Answer:

the correct option is number (3). It corresponds with the expression David factorised.

Step-by-step explanation:

David correctly factored the expression m² - 12m + 64, we want to check which one of the options he wrote.

(1) (m - 8)(m - 8) = (m - 8)²

= m² - 16m + 64

NOT THIS

(2) (m - 8)(m + 8) = m² - 8²

= m² - 64

NOT THIS

(3) (m - 16)(m + 4) = m² + 4m - 16m - 64

= m² - 12m - 64

THIS IS THE CORRECT OPTION AS IT CORRESPONDS WITH THE EXPRESSION DAVID FACTORISED

(4) (m + 16)(m - 4) = m² - 4m + 16m - 64

= m² + 12m - 64

Answer:

trinomial

Step-by-step explanation:

plus and minus signs separate terms.

2x^2 is a term

5x^2 is another term

-8 is another term.

The given algebraic expression is binomial.

The given expression is 2x²+5x²-8 (7x²-8).

We need to check whether the given expression is a monomial, binomial or trinomial.

The different types of algebraic expression are explained below:

Monomial: An algebraic expression which consists of one non-zero term only is called a monomial.

Binomial: An algebraic expression which consists of two non-zero terms is called a binomial.

Trinomial: An algebraic expression of three non-zero terms only is called a trinomial.

Now, the given expression 7x²-8 as two terms.

Therefore, the given algebraic expression is binomial.

The correct option is D. The graph z is representing a quadratic function.

In algebra, a polynomial function with one or more variables in which the highest-degree term is of the second degree is known as a quadratic function, a quadratic polynomial, a polynomial of degree 2, or simply a quadratic.

The general form of the quadratic functions is represented as below:-

y = ax² + bx + c

Where a,b, and c are the constants x and y are variables.

The graph of the quadratic functions will be parabolic on the x-y plane.

Therefore, the correct option is D. The graph z is representing a quadratic function.

Answer:

GCF = x+3

Step-by-step explanation:

(6x+18)/(x^2-x-12) = 6 (x+3)/(x^2 +3x - 4x -12)

                            = 6(x+3)/( x(x+3) - 4(x+3) )

                            = 6(x+3)/( (x-4)(x+3) )

The greatest common factor (GCF) of the numerator and denominator of the rational expression [tex]\frac{(6x+18)}{(x^2-x-12)}[/tex]  is (x + 3) .

The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.  

According to the question

The rational expression :

[tex]\frac{(6x+18)}{(x^2-x-12)}[/tex]

The greatest common factor (GCF)  of the numerator and denominator

Step 1 : We take out factors of numerator

(6x+18) = 6 (x + 3)

Step 2 : Then we take out  factors of denominator

[tex](x^2-x-12)[/tex] = x² - (4-3)x - 12

                    =  x² - 4x + 3x - 12

                    =  x (x - 4) + 3(x - 4)

                    = (x + 3) (x - 4)  

Now , The greatest common factor (GCF)  of the numerator and denominator is  (x + 3)  which is present in both .

Hence, the greatest common factor (GCF) of the numerator and denominator of the rational expression [tex]\frac{(6x+18)}{(x^2-x-12)}[/tex]  is (x + 3) .
