Youre amazing!!! could you help me? 50 points!!! Write an expression that can be used to produce vector d from vector c, and explain how you determined that expression.

Answer:

-2/5

Step-by-step explanation:

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

Answer:

the inches is 2.8 inches

Step-by-step explanation:

if you divide 10 divided by 2 it gives you 5 and then subtract it by 2.2 = 2.8

there goes your answer.

x - 3y = -11
-x + 2y = 7

We minus these equations : x - 3y - (-x + 2y) = -18

= x - 3y + x - 2y = -18
2x - 5y = -18

Now, we add these equations :

x - 3y = -11
-x + 2y = 7
-> x - 3y - x + 2y = -4
-y = -4
y = 4

Replace it in 2x - 5y = -18

2x - 20 = -18

2x = -18 + 20 = 2
x = 1

Recheck : 1 - 3 x 4 = -11

-1 + 8 = 7.

Answer:

  $282

Step-by-step explanation:

The price per ticket can be found by dividing the total cost by the number of tickets, then subtracting the value of any per-ticket add-ons.

  5(x +17) = 1495 . . . . . total cost of 5 tickets with 17 per ticket ins charge

  x +17 = 299 . . . . . . divide by 5

  x = 282 . . . . . . . price of 1 ticket

The price of one ticket is $282.

Answer:

[tex]3x-7y=-10_{(1)} \\x=5y+2_{(2)}\\[/tex]

Substituting Equation 2 into equation 1

[tex]3(5y+2)-7y=-10_{(3)} \\15y+6-7y=-10\\15y-7y+6=-10\\8y+6=-10\\8y=-10-6\\8y=-16\\y=\frac{-16}{8} \\y=-2\\[/tex]

Substitute the value of y into Equation 2

[tex]x=5y+2\\x=5(-2)+2\\x=-10+2\\x=-8\\[/tex]

Therefore x=-8, y=-2

The sine and cosine are related to the definitions because of the identity [tex]\cos^{2}\theta + \sin^{2}\theta = 1[/tex].

The unit circle is a particular case of the Pythagorean theorem, in which hypotenuse ([tex]r[/tex]) has a measure of a unit. That is:

[tex]x^{2}+y^{2} = r^{2}[/tex]  (1)

Where:

If we divide the entire expression by [tex]r^{2}[/tex], then we have the following identity:

[tex]\left(\frac{x}{r} \right)^{2}+\left(\frac{y}{r} \right)^{2} = 1[/tex]

And by trigonometric relations, we have the following formula:

[tex]\cos^{2}\theta + \sin^{2}\theta = 1[/tex]  (2)

Answer:

7/12

Step-by-step explanation:

Draw a rectangle with 12 squares. 5 of them will be pop and 7 will not.

The equation will be 12/12 = 5/12 + n. You will subtract 5/12 from each side and get 7/12 = n.

Answer:

21) 79°

22) 46°

23) 120°

24) 100°

Step-by-step explanation:

79 and 79 are corresponding and congruent. 134 and 46 are supplementary (add to 180). 60 and 120 are supplementary (add to 180). 100 and 100 are alt. exterior and congruent

Step-by-step explanation:

cosine is cos(angle)= adjacent/hypotenuse

sine is sin(angle) = opposite/hypotenuse

Tangent is tan(angle)= opposite/adjacent

for all of those

if the equation is something like tan(69)= x/69

multiply both sides by 69 so it will end up as x=69tan(69) and put that in the calculator

if it is something like tan(69)= 69/x

just swap x and tan(69)

it is much easier

it will then be 69/tan(69) and put that in the calculator

Answer:

1. (x-6)(x+1)

Verify = x² + x - 6x - 6 = x² - 5x - 6

2. (x+8)(x-5)

Using the Central Limit Theorem, it is found that the distribution of the sample mean of six randomly selected bottles is approximately normal, with mean 473 ml and standard error of 1.22 ml.

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

In this problem, for the population, we have that:

[tex]\mu = 473, \sigma = 3[/tex]

Then, for the sample of n = 6:

[tex]s = \frac{3}{\sqrt{6}} = 1.22[/tex]
