$3.54+$23.49= the total cost of calcite and granite

So 3.54+23.49=27.03

The total cost of 0.5 kg of calcite and 3 kg of granite is $23.49

Evaluate the expression
nadezda [96]

Answer:

32

Step-by-step explanation:

We are given the expression:

\frac{-8(13-37)}{6}

and asked to evaluate the expression.

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

Solve inside the parentheses first. Subtract 37 from 13.

⇒ 13-37= -24

\frac{-8(-24 )}{6}

Next, multiply -8 and -24.

⇒ -8*-24= 192

\frac{192}{6}

Finally. divide 192 by 6.

⇒ 192/6 = 32

32

When evaluated, the expression -8(13-37)/6 is equal to 32.

Find the indicated quantities for y equals f (x )equals 3 x squared. ​(A) Simplify StartFraction f (3 plus Upper Delta x )minus
torisob [31]

Answer:

6x

Step-by-step explanation:

Given that a function f(x) is given as

y=f(x) = 3x^2

A) f(x+ \Delta x) = 3((x+ \Delta x)^2=3(x^2+2x \Delta x+\Delta x^2)\\f(x) = 3x^2\\f(x+ \Delta x) -f(x) = 6x  \Delta x +\Delta x^2

Now divide by delta x

\frac{f(x+ \Delta x) -f(x)}{\Delta x}\\=6x+\Delta x

B) When delta x tends to 0, this becomes

6x

(NOte: This is the derivative of f(x))
