I got it correct on the quiz

Answer:

(9,12).

Step-by-step explanation:

If a figure dilated by a scale factor of k and origin is the center of dilation, then the relation between point and its image is defined as

[tex]P(x,y)=P'(kx,ky)[/tex]

It is given that a figure is dilated by a scale factor of 3 and origin is the center of dilation. So,

[tex]P(x,y)=P'(3x,3y)[/tex]

We need to find the image of a vertex located at (3, 4). So, substitute x=3 and y=4 in the above rule of dilation.

[tex]P(3,4)=P'(3(3),3(4))[/tex]

[tex]P(3,4)=P'(9,12)[/tex]

Therefore, the image of a vertex located at (3, 4) is (9,12).

Answer: 9,12

Step-by-step explanation:

Answer:12m

Step-by-step explanation:

The length of the lace required will be the same as that obtained by calculating the perimeter of that table, so p= (L+W)×2

Hence, P=(4m+2m)×2

P= 12m

All the answers is good!

Answer:

2.6 m

Step-by-step explanation:

In the attached diagram

Consider Triangle ABC

[tex]\sin36^\circ =\dfrac{|BC|}{7.8} \\|BC|=7.8*\sin36^\circ\\|BC|=4.5847$ m[/tex]

Our goal is to determine the distance of Jen (at point A) to Holly (at Point D).

In Triangle ABC

[tex]\cos 36^\circ =\dfrac{|AC|}{7.8} \\|AC|=7.8*\cos36^\circ\\|AC|=6.3103$ m[/tex]

In Triangle BDC

Applying Pythagoras Theorem

[tex]|BD|^2=|BC|^2+|CD|^2\\5.9^2=4.5847^2+|CD|^2\\|CD|^2=5.9^2-4.5847^2\\|CD|^2=13.7905\\|CD|=\sqrt{13.7905}=3.7136$ m[/tex]

Now, |AC|=|AD|+|DC|

6.3103=|AD|+3.7136

|AD|=6.3103-3.7136

|AD|=2.5967

|AD|=2.6m (correct to the nearest tenth of a metre)

The distance of Jen from Holly is 2.6m.

Step-by-step explanation:

Answer:

49.81

Step-by-step explanation:

the formula I used is distance=[tex]\sqrt{(x_{2}-x_{1})+(y_{2}-y_{1})}[/tex]

Lets say we are finding the distance from c to y

c=(-6,9)

y=(5,9)

cy=[tex]\sqrt{(5-(-6))^{2}+(9-9)^2 }[/tex]

cy=[tex]\sqrt{(11)^2+(0)^2}[/tex]

cy=[tex]\sqrt{121+0}[/tex]

cy=[tex]\sqrt{121}[/tex]

cy=11

And you can find the distance between y and i, i and d, d and o, o and c, using the same formula.

After solving the distance of all I got

yi=16.55294536

id=1

do=9.219544457

oc=12.04159458

After you add them all up you get 49.8140844 which rounded to the nearest hundredth is 48.81.

Thank you and I hope that is helpful.

Answer:

1/6

Step-by-step explanation:

Out of these four card choices, for the first pick there are two even cards and four cards in total. This means that on the first pick there is a 2/4=1/2 chance that you pick an even card. On the second pick, if you do not replace the card, then there is 1 even card remaining, and 3 cards in total, leaving a probability of 1/3. Multiplying these two probabilities together, you get an overall chance of 1/6. Hope this helps!

Answer:

D. Multiply the second equation by 5

The best answer would have been to multiply the first equation by 1

Answer:

[tex]i^{8}=1[/tex] and [tex]i^{34}=-1[/tex] will be the answer.

Step-by-step explanation:

Since i = [tex]\sqrt{(-1)}[/tex]

i² = (-1)

[tex]i^{3}=-i[/tex]

[tex]i^{4}=(-1)^{2}[/tex] = 1

[tex]i^{8}=1^{2}[/tex] = 1

[tex](i^{8})^{2}=1[/tex]

[tex]i^{34}=[i^{17}]^2[/tex]

     = [tex](i^{8}\times i^{8}\times i)^{2}[/tex]

     = [1 × 1 × √(-1)]²

     = 1² × 1² × [√(-1)]²

     = (-1)

Therefore, [tex]i^{8}=1[/tex] and [tex]i^{34}=-1[/tex] will be the answer.

plzz mark me brainliest

Answer:

y=-1

Step-by-step explanation:

-2×+7y=-5

- -2×-4y=6

11y=-11

But you don't leave the answer like that

You need to simplify

So

11y=-11

y=-11

Answer:

Carmen received $7.14 for each hour she worked.

Step-by-step explanation:

$350 for 49 hours of work

Write an equation, with hours as the variable

$350 = 49h

Divide both sides of the equation by 49 to find the unit rate

h = $7.14

Carmen received $7.14 for each hour she worked.

Answer:

4/8 +6/8 I just verfying the other person's. ok

Step-by-step explanation:

I did it on a calculator ;b

PLEASE MARK FallOutChild brainliest!!

Answer:

4/8 + 6/8 = 10/8 or 1 2/8, 1 1/4

Step-by-step explanation:

When it asks for like units, it's asking for the same denominator value. You can not add fractions together when they do not have a common denominator

if you multiply the denominator and numerator in 2/4 by 2, you get 4/8

Result of 4/8 + 6/8 gives you an improper fraction of 10/8

Answer:

[tex] y = A sin (kx \pm wt)[/tex]

Where k represent the number of wave [tex]k =\frac{2\pi}{\lambda}[/tex] and [tex] w =\frac{2\pi}{T}[/tex] represent the angular frequency with T the period.

For this case we know tha T = 520 nm

And the angular frequency would be given by:

[tex] w = \frac{2\pi}{520}= \frac{pi}{260}[/tex]

So then the possible anwer for this case would be:

D.) y= sin pi/260 theta

Since is the only option with satisfy the general equation of a wave.

Step-by-step explanation:

Since the sine function can be used to model light waves we can use the following general expression:

[tex] y = A sin (kx \pm wt)[/tex]

Where k represent the number of wave [tex]k =\frac{2\pi}{\lambda}[/tex] and [tex] w =\frac{2\pi}{T}[/tex] represent the angular frequency with T the period.

For this case we know tha T = 520 nm

And the angular frequency would be given by:

[tex] w = \frac{2\pi}{520}= \frac{pi}{260}[/tex]

So then the possible anwer for this case would be:

D.) y= sin pi/260 theta

Since is the only option with satisfy the general equation of a wave.

Answer:2.5 cups

Step-by-step explanation:

Given

Rosanne runs 6 miles in an hour

If she drinks 0.5 cups of water every  [tex]\frac{1}{3}[/tex]  of an hour

So in 1 hour Rosanne drinks 1.5 cups

So, for 6 miles Rosanne drinks 1.5 cups

i.e. For   [tex]1\ mile \quad \equiv \quad \frac{1}{4}\ \text{cup}[/tex]

for    [tex]10\ mile\quad \equiv \quad \frac{10}{4}\ \text{cup}[/tex]
