Answer:

How many pairs of socks fits in a suitcase.

How much rice fits in a jar

How much cardboard is needed to make a box.

Step-by-step explanation:

Given:

The two vectors are:

[tex]\overrightarrow{a}=2\hat{i}-\hat{j}+\hat{k}[/tex]

[tex]\overrightarrow{b}=\hat{i}-3\hat{j}+5\hat{k}[/tex]

To find:

The value of [tex]|\overrightarrow{a}\times \overrightarrow{b}|[/tex].

Solution:

We have,

[tex]\overrightarrow{a}=2\hat{i}-\hat{j}+\hat{k}[/tex]

[tex]\overrightarrow{b}=\hat{i}-3\hat{j}+5\hat{k}[/tex]

The cross product of these two vectors is:

[tex]\overrightarrow{a}\times \overrightarrow{b}=\begin{vmatrix}\hat{i}&\hat{j}&\hat{k}\\2&-1&1\\1&-3&5\end{vmatrix}[/tex]

[tex]\overrightarrow{a}\times \overrightarrow{b}=\hat{i}[(-1)(5)-(1)(-3)]-\hat{j}[(2)(5)-(1)(1)]+\hat{k}[(2)(-3)-(-1)(1)][/tex]

[tex]\overrightarrow{a}\times \overrightarrow{b}=\hat{i}[-5+3]-\hat{j}[10-1]+\hat{k}[-6+1][/tex]

[tex]\overrightarrow{a}\times \overrightarrow{b}=-2\hat{i}-9\hat{j}-5\hat{k}[/tex]

Now the magnitude of the cross product is:

[tex]|\overrightarrow{a}\times \overrightarrow{b}|=\sqrt{(-2)^2+(-9)^2+(-5)^2}[/tex]

[tex]|\overrightarrow{a}\times \overrightarrow{b}|=\sqrt{4+81+25}[/tex]

[tex]|\overrightarrow{a}\times \overrightarrow{b}|=\sqrt{110}[/tex]

Therefore, the value of [tex]|\overrightarrow{a}\times \overrightarrow{b}|[/tex] is [tex]\sqrt{110}[/tex].

Answer:

z=20

Step-by-step explanation:

(2z + 16) +124 =180

2z + 16 +124

2z +  140 = 180

2z     -140 -140

2z        =  40

z           =  20

9514 1404 393

Answer:

  y = -|x -1| +2

Step-by-step explanation:

The transformation ...

  -f(x -h) +k

reflects function f(x) over the x-axis, translates it 'h' units to the right and 'k' units up.

Your absolute value function is reflected over the x-axis, then translated 1 unit right (h=1) and 2 units up (k=2). Putting these values in the function, we have ...

  y = -abs(x -1) +2

  y = -|x -1| +2

Answer:

1. B.

2. A, E.

3. D.

Step-by-step explanation:

1. 8.225 ÷ 5 = 1.645

2. 892 ÷ 8 = 111.5

8920 ÷ 80 = 111.5

894 ÷ 10 = 89.4

89.2 ÷ 0.08 = 1115

8.92 ÷ 0.8 = 11.15

0.892 ÷ 0.008 = 111.5

3. 4367 ÷ 0.004 = 1,091,750

Answer:

a): 68

b): 32

Step-by-step explanation:

In a triangle, there is a total of 180 degrees

We are given 2 out of the 3 angles, 54 and 58 degrees

180-54-58= 68 degrees

In the other angle, both lines form a 90-degree angle

We are given 58 degrees, so the rest must be 32.

Answer:

$104.64

Step-by-step explanation:

Because coupons come before tax, we have to take away 20%, then add 9%

Step 1 : Find 20%

In order to find the percent of anything, all you have to do is multiply the percent (as a decimal) by your price

In this case, it's :  120 × 0.20

Using this expression, we find that 20% of $120 = $24

Step 2 : take away 20%

Coupons take away money from a full price, so we will take away $24 from $120, leaving us with $96

Step 3 : Find 9%

Now we multiply 0.09 (9%) by our new price (96)

96 × 0.09 = $8.64

Step 4 : Add 9%

Lastly, we use our coupon-added price (96) and add our tax (8.64)

96 + 8.64 = $104.64

Answer:

-4(3c + 4)(c + 1)

Step-by-step explanation:

Reorder the expression

-12c² - 28c - 16

Divide it by -4

3c² + 7c + 4

Factor it by multiplying a (3) and c (4), then finding 2 factors that add up to b (7)

Two factors of 12 that add up to 7 are 4 and 3.

Use 4c and 3c to substitute for 7c in the expression, and simplify

3c² + 7c + 4

3c² + 3c + 4c + 4

3c(c + 1) + 4(c + 1)

(3c + 4)(c + 1)

Since we factored out a -4 in the beginning, add this in front

-4(3c + 4)(c + 1)

Answer:

In 5 hours he would have 7.5 inches of snow JUST from the snowstorm but the question says that he already had 5 inches in his lawn so that would make 12.5 inches of snow in 5 hours.

The second one says t, it doesn't state a number so lets assume the number is ten. So that's 5 more hours of constant snowfall, this makes our total be the sum of 12.5+7.5. This is equal to 20.

10 hours into the snowstorm Nathaniel had 20 inches of snow in his lawn.

Consider a brainliest if it helps :)

Answer:

Snow after 5 hours = 12.5

Show after t hours= 1.5t+5

Answer:

All of the teenagers in the United States sent about 69,300,000,000 text messages each month.

Step-by-step explanation:

Given that in 2019, there were about 21 million teenagers in the United States, and they each sent an average of 3,300 text messages per month, to determine about how many text messages did all of the teenagers in the United States send each month the following calculation should be done:

21,000,000 x 3,300 = X

69,300,000,000 = X

Therefore, all of the teenagers in the United States sent about 69,300,000,000 text messages each month.

Answer:

I dont understand spanish!

Step-by-step explanation:

Answer: I would find it by counting the squares so that you can get 2 numbers and then do the formula for the area of a parallelogram. For the sides to find the number, you might want to draw a square around the parallelogram so that you get a triangle and then use the Pythagorean theorem to find the side of the parallelogram.

Step-by-step explanation:

Triangle ABC was reflected across the y-axis and then translated 7 units down.

Answer:

x=−2

y=−4

Step-by-step explanation:

−2x+2y=−4

3x+3y=−18

In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.

−2x+2y=−4,3x+3y=−18

To make −2x and 3x equal, multiply all terms on each side of the first equation by 3 and all terms on each side of the second by −2.

3(−2)x+3×2y=3(−4),−2×3x−2×3y=−2(−18)

Simplify.

−6x+6y=−12,−6x−6y=36

Subtract −6x−6y=36 from −6x+6y=−12 by subtracting like terms on each side of the equal sign.

−6x+6x+6y+6y=−12−36

Add −6x to 6x. Terms −6x and 6x cancel out, leaving an equation with only one variable that can be solved.

6y+6y=−12−36

Add 6y to 6y.

12y=−12−36

Add −12 to −36.

12y=−48

Divide both sides by 12.

y=−4

Substitute −4 for y in 3x+3y=−18. Because the resulting equation contains only one variable, you can solve for x directly.

3x+3(−4)=−18

Multiply 3 times −4.

3x−12=−18

Add 12 to both sides of the equation.

3x=−6

Divide both sides by 3.

x=−2

The system is now solved.

x=−2,y=−4

Answer:

the slope is 2 and the y intercept is 1.

Step-by-step explanation:

find 2 points and plug into this formula. (Y2-Y1)/(X2-X1)

(3-1)/(1-0)=2

y intercept is just when X equal to 0, what is y. Therefore, find X=0 on the graph. X=0, Y=1
