The matrix is not invertible because the matrix has 2 pivot positions. D. The matrix is invertible because its columns are multiples of each other. The columns of the matrix form a linearly dependent set.
Answers
Answer:
A. The matrix is not invertible because its determinant is zero.
Step-by-step explanation:
The matrix is invertible if the columns and rows are equal. The square matrix is invertible because it has equal rows and columns. The determinant of the matrix is zero then the matrix is no invertible.

Answer:
cos 45 degree = A/H
cos 45 degree = 2 square root 2 / x
x = 2 square root 2 / cos 45 degree
x = 4
Sin 45 degree = O/H
Sin 45 degree = y/ 4
4 x Sin 45 degree = y
y = 2.83
or
we could use tan
tan 45 degree = O/A
tan 45 degree = y / 2 square root 2
2 square root 2 x tan 45 degree = y
y = 2.83

How many grams does the exotic fruit weigh if the total weight of all ten items is 84 grams?
Answers
Answer:
The mass of the exotic fruit is 20 grams.
Step-by-step explanation:
For the system to be in equilibrium,
i. the resultant of all masses must be zero
ii. the total mass on the left of the hanger must be equal to that on the right
Thus,
84 g = 42 g + 42 g
mass of each carrot = 12 g
mass of each mushroom = 10 g
mass of each cherry = 2.5 g
mass of each strawberry = 5 g
So that;
On the left of the hanger,
(2 x 5) + (2 x 10) + 12 = 42
10 + 20 + 12 = 42
42 = 42
On the right of the hanger, let the mass of exotic fruit be represented by x.
x + 12 + 5 + (2 x 2.5) = 42
x + 12 + 5 + 5 = 42
x + 22 = 42
x = 20 g
The mass of the exotic fruit is 20 grams.

Answer: 1 is D and 2 is B I think
Step-by-step explanation: 1 is D because 59.2 + (-84.7) because D is the same thing as 59.2-84.7, just written differently. 2 is B because the longer line resembles -15 and the smaller line resembles 6. -9 is circled because its supposed to add up to -9, hence why it would be 6+(-15)=-9.

find the exact value of sin a = 4/5, a lies in quadrant 2, and cos B = 2/5, B lies in quadrant 1 find cos(a-b)
Answers
Answer:
Cos(a - b) = 0.959
Step-by-step explanation:
We know that:
Sin(a) = 4/5
Such that a is on the first quadrant (between 0° and 90°)
then:
Sin(a) = 4/5
Asin(sin(a)) = Asin(4/5)
a = Asin(4/5) = 53.13°
And:
Cos(b) = 2/5
Then:
Acos(Cos(b)) = Acos(2/5)
b = Acos(2/5) = 36.67°
Then:
Cos(a - b)
where:
a = 53.13° and b = 36.67°
Then:
Cos(a - b) = Cos(53.13° - 36.67°) = 0.959

Enter the value of w so the expression -5 +0.6W is equivalent to w (2.5 – 0.3w)
Answers
9514 1404 393
Answer:
w = -2 or 8 1/3
Step-by-step explanation:
Setting the two expressions equal makes a quadratic equation:
-5 +0.6w = w(2.5 -0.3w)
0.3w^2 -1.9w -5 = 0 . . . . . . subtract the right-side expression
3w^2 -19s -50 = 0 . . . . . . . multiply by 10 to give integer coefficients
(3w -25)(w +2) = 0 . . . . . . . factor
We can use the zero product rule to find the solutions. The product will be zero only if a factor is zero.
3w -25 = 0 ⇒ w = 25/3 = 8 1/3
w +2 = 0 ⇒ w = -2
The values of w that make the two expressions equivalent are -2 and 8 1/3.

On a time crunch!!!!!
Answers
Answer: x = 0
Step-by-step explanation:
Subtract 6x^3+29x^2+47x+28 from both sides:
(2^2 + x + 4) (x - 7) - 6x^3+29x^2+47x+28
(6x^3+29x^2+47x+28)-6x^3+29x^2+47x+28
= -4x^3 - 14x^2 - 36x = 0
Now factor the left side:
-4x^3 - 14x^2 - 36x = 0
(-2x) (2x^2 + 7x + 18) = 0
Now set the factors equal to 0
-2x = 0 or 2x^2 + 7x + 18 = 0
x = 0

Use slope-intercept form to write an equation of a line passing through the given point and having the given slope. Express the answer in standard form.
P(−4, −6); m = −3/4
Answers
9514 1404 393
Answer:
3x +4y = -36
Step-by-step explanation:
The slope-intercept form is ...
y = mx + b
where m is the slope and b is the y-intercept. From this equation, we can find the y-intercept as ...
b = y -mx
For the given point and slope, this is ...
b = -6 -(-3/4)(-4) = -9
Then the slope-intercept equation is ...
y = -3/4x -9
We can multiply by 4 to get something we can put in standard form.
4y = -3x -36
3x +4y = -36 . . . . standard form equation

There are 90 million pet dogs in the US. The number of dogs is 1000% the number of reptiles. How many reptiles are there?
Answers
Answer:
There are 9 000 000 = 9 million reptiles in the US.
Step-by-step explanation:
Percentages and ratio:
The double of a measure, for example, is 200% of the measure.
So 1000% of a measure is 10 times the measure.
There are 90 million pet dogs in the US. The number of dogs is 1000% the number of reptiles.
The number of pet dogs is 10 times the number of reptiles, which means that:
[tex]10x = 90 000 000[/tex]
[tex]x = \frac{90 000 000}{10}[/tex]
[tex]x = 9 000 000[/tex]
There are 9 000 000 = 9 million reptiles in the US.
