Answer:

Magnitude is 5

Step-by-step explanation:

Using the formula for calculating the distance between two points expressed as:

D = √(x2-x1)²+(y2-y1)²

Given the coordinates  (3,5) and (-1,2)

D = √(2-5)²+(-1-3)²

D = √(-3)²+(-4)²

D = √9+16

D = √25

D = 5

Hence the magnitude is 5

Answer:

Step-by-step explanation:

Looking at the Venn diagram :

The total number of students surveyed is 7+5+8+6+2+4+3+6 = 41

The number of students that studies physics is = 14

The number of students that studies chemistry is =  21

Probability  = number of favorable outcomes / total number of outcomes

Therefore  the probability that a student chosen at random studies physics and chemistry or both is  35/41 = 0.85

Answer:

a) x(x-2)

b) 6x(2x+2)

dont know c and d sorry

Step-by-step explanation:

Answer:

Below.

Step-by-step explanation:

You can use any 4 x values, so we could have:

- 2  0  2  4

Now find the corresponding y values by substitution in the equation:

For x = -2, y = 1/2 *-2 + 2 = 1.

For x = 0, y = 1/2 * 0 + 2 = 2.

For x = 2 , y = 1/2* 2 + 2 = 3.

For x =  4 , y = 1/2 * 4 + 2 = 4.

So the table is:

-2   0    2   4

1    2    3   4

You then plot the points (-2, 1), (0, 2), (2, 3) AND (4, 4) on the grid  and draw a line through them The graph will be a straight line.

Answer:

x = 16[tex]\sqrt{3}[/tex]

y = 8[tex]\sqrt{3}[/tex]

Step-by-step explanation:

For this type of equation, you are going to use the following trigonometric signs tangent and cosine.  Tangent is used for the y-variable and cosine is used for the x-variable.  For the y-variable, it is 24 tan 30 to get 8 root 3 as your answer.  For the x-variable, you would get ([tex]\sqrt{3}[/tex] / 2)x = 24.  Divide that root number to get 16[tex]\sqrt{3}[/tex] as your x variable.

Answer: 16 sqrt 3. 8 sqrt 3

Answer:

m = -1

Step-by-step explanation:

y = -x can also be written as

y = -1x + 0

The slope is -1.

In slope intercept equations, if the slope is '1' or '-1' they would usually drop the one.

Hope this helps.

Answer:

By substituting x = -1/2, the expression [tex]\(f(x) = \frac{\sqrt{2x} + 3}{6x - 5}\)[/tex] can be simplified to[tex]f(x) = \(f(-\frac{1}{2}) = \frac{\sqrt{3 - \sqrt{2}}}{-8}\).[/tex].

To find [tex]\(f(-\frac{1}{2})\)[/tex], substitute [tex]\(-\frac{1}{2}\)[/tex] into the function f(x):

[tex]\(f(-\frac{1}{2}) = \frac{\sqrt{2 \cdot (-\frac{1}{2}) + 3}}{6 \cdot (-\frac{1}{2}) - 5}\)[/tex]

Now, simplify the expression inside the square root:

[tex]\(f(-\frac{1}{2}) = \frac{\sqrt{-\sqrt{2} + 3}}{-3 - 5}\)\\\(f(-\frac{1}{2}) = \frac{\sqrt{3 - \sqrt{2}}}{-8}\)[/tex]

So, [tex]\(f(-\frac{1}{2}) = \frac{\sqrt{3 - \sqrt{2}}}{-8}\)[/tex].

Answer:

The unit rate that Jeremy can row is 1.33 miles per hour.

Step-by-step explanation:

Unit rate is defined as the distance over a time period. The distance that Jeremy can row is given and the time period is given.

The distance (miles)=1/3=0.3333333...

time period: 1/4

0.33333/0.25=1.333333

Step-by-step explanation:

ohh ok i understand TUV is (x,y)

so (x+8,y-3) is the T'U'V

so subtract 8 and add 3 to this translation

(x-8,y+3)

looking at U

t goes to (10,-5)

and that is the only one so the answer is D

The coordinates or TUV are  (-6,-3),(-1,6),(0,-2), the correct option is C.

(SCALING ZOOMING SIMILAR FIGURES)

Suppose a figure (pre image) is dilated (dilated image) by scale factor of k.

So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:

L = k × M

where 'k' will be called as scale factor.

The linear things grow linearly like length, height etc.

The quantities which are squares or multiple of linear things twice grow by square of scale factor. Thus, we need to multiply or divide by k² to get each other corresponding quantity from their similar figures' quantities.

So area of first figure = k² × area of second figure

Similarly,

Volume of first figure = k³ × volume of second figure.

It is because we will need to multiply 3 linear quantities to get volume, which results in k getting multiplied 3 times, thus, cubed.

Given;

TUV is translated to image T'U'V , as shown below , by the rule (x,y) -> (x+8, y-3)

Coordinates of T'U'V; (2,-6),(7,3),(8,-5)

Now, coordinates of TUV;

T coordinate=(-6,-3)

U coordinate=(-1,6)

V coordinate=(0,-2)

Therefore, coordinates before dilation will be (-6,-3),(-1,6),(0,-2)
