Answer:
the Smith family pay for the meal = $ 36.39Step-by-step explanation:
The Smith family went out to dinner . The price of the meal was $ 29.85 .
The sales tax was 6 % of the price of the meal .
LEts find sales tax amount sales tax amount = price of meal *
sales tax 6 % ( 0.06 ) = 29.85 * 0.06 = 1.791 sales tax amount = 1.791
Price of the mean with sales tax = 29.85 + 1.791 = 31.641
The tip was 15 % of the meal and the sales tax now we find out tip amount for 31.641 15 % is 15 / 100 = 0.15
Tip amount = 31.641 * 0.15 = 4.74615
Now we add the top amount with 31.641 31.641+ 4.74615 = 36.38715
the Smith family pay for the meal = $ 36.39
what is the minimum value of the parabola y = x^2 + 10 ?
If f(x) = 2 (3x) + 1 , what is the value of f(2) ?
Answer:
13
Step-by-step explanation:
f(x)=2(3x)+1
f(2)=2(3X2)+1
f(2)=2(6)+1
f(2)=12+1
f(2)=13
The value of function f(2) is 13.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
Given function; f(x) = 2 (3x) + 1
We need to find the value of f(2) .
f(x) = 2(3x)+1
f(2) = 2(3 * 2)+1
f(2) = 2(6)+1
f(2)=12+1
f(2)=13
Therefore, the value of function f(2) is 13.

Answer:
Ac_11 = -13
Ac_12 = 44
Ac_13 = 27
Step-by-step explanation:
Plato
The cofactors of each entry in the first row of the matrix are
Ac_11 = -13
Ac_12 = 44
Ac_13 = 27
We have to determine the cofactors of each entry in the first row of the matrix.
What is the matrix?
A set of numbers is arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries, of the matrix.
Therefore the cofactors of each entry in the first row of the matrix is
Ac_11 = -13
Ac_12 = 44
Ac_13 = 27

estimate a 15% on a dinner bill of $42.58 by first rounding the bill amount to the nearest ten dollars
Answer:
$6
Step-by-step explanation:
Round $42.58 to the nearest ten dollars to get $40. $40 ÷ 100 = $0.4 so this is one percent. $0.4 × 15 is $6 which is an estimate of 15% of $42.58.
The answer is $6 (unless if you are meant to add this to $42.58 - then the answer would be $48.58 - but I am not sure because of the wording of the question).

Answer:
-17√2 /26 or -0.9247 to the nearest ten thousandth.
Step-by-step explanation:
The hypotenuse of the right triangle in which tan x = 2/3 is √(2^2 + 3^2)
= √13 so sin x = 2/√13 and cos x = 3/√13
sin2x = 2sinxcos
= 2* 2/√13 * 3/√13
= 12/13.
cos2x = cos^2x - sin^2x
= 9/13 - 4/13
= 5/13.
sin(2x + 5π/4)
= sin2x cos5π/4 + cos2x sin5π/4
= 12/13 * -1/√2 + 5/13 * -1/√2
= -12 / 13√2 - 5 / 13√2
= -17/13√2
= -17√2 /26.

f(x) = -3(x + 7)(x + 4),
Remember that to solve for the x-intercepts we equate y to 0,
-3(x + 7)(x + 4) = 0
Using the zero product property,
x + 7 = 0, x + 4 = 0
x = - 7, x = -4
x -intercepts: (- 7, 0) & (- 4, 0)
Hence proved.
