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

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.

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.

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.

Three coins are tossed simultaneously 350 times. The distribution of various outcomes is listed below :Outcome3 Tails2 Tails1 TailNo TailsNo. Of times65 95 110 80 respevtove;y Compute the probability of getting:(i)At least 1tail(ii) Exactly 3 heads
Answer:
(i) [tex]\frac{27}{35}[/tex]
(ii) [tex]\frac{8}{35}[/tex]
Step-by-step explanation:
Probability refers to chances of occurrence of any event.
Probability is calculated by dividing number of favorable outcomes by total number of possible outcomes.
Total number possible of outcomes = 350
(i)
Number of favorable outcomes = [tex]65+95+110=270[/tex]
Probability [tex]=\frac{270}{350}=\frac{27}{35}[/tex]
(ii)
Exactly 3 heads is equivalent to no tails.

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).
A hybrid SUV can travel 400 miles on a 15-gallon tank of gas. How many miles can it travel on 6 gallons of gas?
Answer:
160miles
Step-by-step explanation:
400miles uses15g what about 6g.
Using cross multiplication. Multiply 6x400/15 = 160miles
Answer:
160 miles
Step-by-step explanation:
If it travels 400 miles on 15 gallons, then it will travel x miles on 6 gallons
400 miles -> 15 gallons
x miles -> 6 gallons
15 * x = 6 * 400
15x = 2400
x = 2400 / 15
x = 160 miles
