Step-by-step explanation:
The given matrix has a determinant of zero thus it will not have any inverse.
What is a matrix?matrix, a collection of numbers lined up in rows and columns to produce a rectangular array. The elements of the matrix, also known as the entry, are the numerals.
In another word, a matrix is a set of variables that are arranged in such a good way that we can create an algebraic equation from that.
In computer graphics, where they have been used to describe picture transformations and other alterations, matrices have vital applications as well in many sectors.
Given the matrix
[tex]\begin{bmatrix}16 & -4 \\8 & -2 \end{bmatrix}[/tex]
The determinant of this matrix is 16(-2) - (8)(-4)
⇒-32 + 32 = 0
Since the determinant of the given matrix is zero so there will be no inverse.
Hence "The given matrix has a determinant of zero thus it will not have any inverse".

B
82
18
A
80
Find cos B.
Answer:
[tex]\cos B=\dfrac{9}{41}[/tex]
Step-by-step explanation:
Given that,
Hypotenuse = 82 units
Base = 80 units
Height = 18 units
We need to find the value of cos B.
We know that,
[tex]\cos\theta=\dfrac{Base}{Hypotenuse}[/tex]
For angle B, Hypotenuse = 82 units, Height = 80 units and base = 18 units
[tex]\cos B=\dfrac{18}{82}\\\\\cos B=\dfrac{9}{41}[/tex]
Hence, the correct option is (A).

What is the expression and value of "six less than the quotient of a number and two, increased by ten" when n= 8? O 122 - 6+ 10; when n= 8, the value is 8. 12 O B- 6- 5+10; when n = 8, the value is 12. 02-6+10; when n = 8, the value is 11. O 6-9 +10, when n = 8, the value is 9
Answer:
the answer is 8
Step-by-step explanation:
the expression is written as (n/2 - 6)+ 10
therefore when n=8..
(8/2 - 6) + 10
we now have, (4-6)+10
(-2)+10=8...

What is the value of the expression 3 over 4 to the power of 3
Answer:
[tex]( \frac{3}{4} ) ^{3} \\ \frac{3 {}^{3} }{4 {}^{3} } \\ \frac{3 \times 3 \times 3}{4 \times 4 \times 4 } \\ \frac{27}{64} [/tex]
Option 2 is the correct answer.
Answer:
2nd Option[tex] \frac{27}{64} [/tex]
Step-by-step explanation:
Here,
[tex] { (\frac{3}{4} )}^{3} [/tex]
[tex] = \frac{3 \times 3 \times 3}{4 \times 4 \times 4} [/tex]
[tex] = \frac{27}{64} [/tex]
Hence,
2nd option is the correct answer.
Solve 169x^2-42.25=0 by using square roots?
NEED HELP!!!
Answer:
x = 1/2 , x = -1/2
Step-by-step explanation:
Given equation;
169x² - 42.25
Find:
Solution of equation using square root
Computation:
169x² - 42.25
We know that 13² = 169 and 6.5² = 42.25
So,
[13x]² - [6.5]²
a² - b² = (a + b)(a - b)
So,
[13x]² - [6.5]² = [13x + 6.5][13x - 6.5]
So,
13x + 6.5 = 0 , 13x - 6.5 = 0
x = 6.5 / 13 , x = -6.5 / 13
x = 1/2 , x = -1/2
there are two pans of lasagna at a school dinner. parents were careful to cut each pan of lasagna into equal portions. Tanya had 2 portions in one pan, while Daniel took 4 portions from the other pan. They both took the same amount of lasagna. he is this possible?
1. show how the lasagna was divided into portions so Tanya's 2 portion are equal to Daniel
2a. what fraction did Tanya eat?
1b. what fraction did Daniel eat.
2.how do you know these fractions are equivalent?
Answer:
1. Tanya ate 2/3 of the lasagna and Daniel ate 4/6 of the lasagna.
2a. 2/3
1b. 4/6
2. 2/3 is the same thing as 4/6, 2/3 x 2/2=4/6, 4/6÷2/2=2/3

Find the are of the composite shape.
mm?
Answer:
18 feet²
Step-by-step explanation:
A composite figure is made up of simple geometric shapes. To find the area of a composite figure or another irregular-shaped figure, divide it into simple, nonoverlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure.
Finding the Area of Composite Shapes
In order to find the composite area of two or more shapes, simply find the area of each shape and add them together. Therefore, the answer is 96 feet²
The midpoint of QR is (4, -1).
Q = (3.1)
What are the coordinates of point R?
Answer:
(5,-3)
Step-by-step explanation:
Given that,
The coordinates of Q = (3,1)
The midpoint of QR = (4,-1)
We need to find the coordinates of point R.
We know that, according to mid-point theorem,
[tex](x_m,y_m)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
Let (x₂,y₂) be the coordinates of point R.
So,
[tex](4,-1)=(\dfrac{3+x_2}{2},\dfrac{1+y_2}{2})\\\\\dfrac{3+x_2}{2}=4\ and\ \dfrac{1+y_2}{2}=-1\\\\3+x_2=8\ and\ y_2+1=-2\\\\x_2=5\ and\ y_2=-3[/tex]
So, the coordinates of point R is (5,-3).

A gain of seven yards in football is represented by 7. What number represents a loss of
seven yards?
A 0
B. 7
C. -(-7)
D. -7
Answer:
D. -7
Step-by-step explanation:
Since positive 7 represents a gain of seven yards, a loss would be represented by a negative number.
So, a loss of seven yards will be represented by -7.
So, the correct answer is D. -7

On a trip across the country Joe used 20 gallons of gas to go 300 miles. At this rate, how much gas must he use to go 3600 miles?
HELP
Answer:
240 gallons
Step-by-step explanation:
Let's set up an ratio where g = gallons and m = miles:
20g = 300m
We need the right side of that to be 3600, so multiply both sides by 12:
12(20g) = 12(300m)
Answer: 240 gallons for 3600 miles
