Answer:

B(-2,-3).

Step-by-step explanation:

The given points are A(-6,-5) and C(4,0).

We need to find the coordinates of point B on segment AC such that AB:BC=2:3.

It means point B divides the line segment AC in the ratio of 2:3.

Section formula: If a point divide a line segment in m:n, then

[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]

Using section formula, the coordinates of point B are

[tex]B=\left(\dfrac{2(4)+3(-6)}{2+3},\dfrac{2(0)+3(-5)}{2+3}\right)[/tex]

[tex]B=\left(\dfrac{8-18}{5},\dfrac{0-15}{5}\right)[/tex]

[tex]B=\left(\dfrac{-10}{5},\dfrac{-15}{5}\right)[/tex]

[tex]B=\left(-2,-3\right)[/tex]

Therefore, the coordinates of point B are (-2,-3).

Answer:

Therefore, the coordinates of point B are (-2,-3).

Answer: w might be 9

Step-by-step explanation: the length of each sides of the smallest shaped polygon is 3 times less( like 6 in the biggest shape, it is 2 in the smallest one= 6/3:2) x might be 12 . And in other ways we can say that each length of the biggest shaped polygon is 3× the length of the smallest one.

Answer:

solution,

The two polygons are same.

[tex] \frac{4}{x} = \frac{y}{15} = \frac{3}{w} = \frac{2}{6} = \frac{z}{4} [/tex]

[tex] \frac{3}{w} = \frac{2}{6} \\ or \: 2w = 3 \times 6( \: cross \: multiplication) \\ or \: 2w = 18 \\ or \: w = \frac{18}{2} \\ w = 9[/tex]

Answer:

sin = 12/13 and tan = 12/5

The value of sin α will be 12/13 and tan α  will be 12/5 for the given triangle such that cosα= 5/13.

Trigonometric functions are functions for right angle triangle which gives the relation between the angle and sides of the triangle.

The trigonometric function is only valid for the right angle triangle and it is 6 functions which are given as sin cos tan cosec sec cot.

The trigonometric functions are found in the four quadrants, as well as their graphs, domains, and differentiation and integration.

We know that

sin²α  + cos²α  =1  ⇒ sin²α  = 1 - cos²α

Given that cosα = 5/13 so by putting it

sin²α  = 1 - (5/13)²

sin²α  = 144/169  ⇒ sinα = 12/13.

Now since tanα = sinα /cosα  

tanα  = (12/13) ÷ ( 5/13)

tanα = 12/5.

Hence the value of sinα will be 12/13 and tanα will be 12/5.

Answer:

See below.

Step-by-step explanation:

[tex]\frac{6z^2-12z}{4z^2-16z+16} +\frac{3z}{z^2-z-2} \\\\[/tex]

First, factor the numerators and the denominators:

[tex]=\frac{6z(z-2)}{4(z^2-4x+4)}+\frac{3z}{z^2-z-2}\\=\frac{6z(z-2)}{4(z-2)^2}+\frac{3z}{(z-2)(z+1)}\\=\frac{3z}{2(z-2)}+\frac{3z}{(z-2)(z+1)}[/tex]

Now, make the two denominators equivalent. To do this, we can multiply the first term by (z+1) and multiply the second term by 2. This will give us:

[tex](\frac{z+1}{z+1} )(\frac{3z}{2(z-2)})+(\frac{2}{2})(\frac{3z}{(z-2)(z+1)})\\=\frac{3z(z+1)}{2(z-2)(z+1)}+\frac{6z}{2(z-2)(z+1)} \\[/tex]

Now, combine them since they have a common denominator:

[tex]=\frac{3z^2+3z+6z}{2(z-2)(z+1)}\\ =\frac{3z^2+9z}{2(z-2)(z+1)} \\=\frac{3z(z+3)}{2(z-2)(z+1)}[/tex]

This cannot be simplified further.

Answer:

15/64

Step-by-step explanation:

3 blue

5 red marbles.

since the marble is put back in, the denominator will not change,

so to draw ONE marble, the chances would be

chances of picking a blue marble 3/8

chances of picking a red marble 5/8

3/8 * 5/8 - 15/64

please mark me brainly.

Answer:

The probability of drawing one blue marble is 3/8 because you have three blue marbles out of a total of eight marbles. The probability of drawing a second blue marble is also 3/8 but since you have to draw both marbles consecutively you have to multiply the probabilities of drawing each marble. So,

3/8•3/8 = 9/64.

Now you need to change it to a percent.

We do this by

9/64 x 100 = 14% approx

Answer: a) 26

Step-by-step explanation:

-a would be because as you can see there is a pattern of sticks, so what i did was count up the sticks and i found that there was 6 in the first one. So i counted the second one and it was 10 so i realized that all i had to do was add 4.

and for b i think when it says n it means the nth term which is 4 so i think it means pattern 4 which would be 18 so try that out

Answer:

see below

Step-by-step explanation:

Formula: Center Not at Origin:

New point = k( x-a) +a, k( y-b) +b  where k is the scale factor and ( a,b) is center of dilation

New point = -2( x-4) +4, k( y-6) +6  

The scale factor is k = -2

Taking the top point ( 1,9)

New point = -2( 1-4) +4, -2( 9-6) +6

                   = -2(-3) +4 , -2(3) +6

                       6+4, -6+6

                         10,0  

Taking the bottom left point ( 1,7)

New point = -2( 1-4) +4, -2( 7-6) +6

                   = -2(-3) +4 , -2(1) +6

                       6+4, -2+6

                         10,4  

Taking the bottom right point ( 2,7)

New point = -2( 2-4) +4, -2( 7-6) +6

                   = -2(-2) +4 , -2(1) +6

                       4+4, -2+6

                         8,4  

Answer:

c = 21

Step-by-step explanation:

c + 2c + 12 = 75

Combine like terms.

3c + 12 = 75

Subtract 12 from both sides.

3c = 63

Divide 3 on both sides.

c = 21

Answer:

x = 6

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, thus

6x - 15 = x + 15 ( subtract x from both sides )

5x - 15 = 15 ( add 15 to both sides )

5x = 30 ( divide both sides by 5 )

x = 6

Answer:

X=6 Read explination

Step-by-step explanation:

A parallelogram has the perrimeter of both opposite sides equal

So we know that

6x-15=x+15

This is because in a parrellelogram the opposite sides are equal  

so breaking it down

6x-15=x+15

(add 15 to both sides)

6x=x+30

(subtract x from both sides)

5x=30

(divide both sides by 5)

x=6

Answer:

  23.9% decrease

Step-by-step explanation:

The percentage change is calculated from ...

  pct change = ((new value)/(old value) -1) × 100%

  = (2653/3487 -1) × 100% = -0.2392 × 100%

  pct change = -23.9% . . . . rounded to tenths

The population decreased by 23.9% in the given time period.

Answer:

-4 + 4

Step-by-step explanation:

It is -4 + 4 because if you imagine on a number line, you go left 4 (since it is negative) and add 4, so you go to the right 4, which leaves to 0.

Or, you can think of it like this:

+4 - 4

= 4 - 4

= 0.

I hope this helps. Sorry if I was wrong

Answer:

Answer:

a). [tex]V=\frac{U.F}{U-F}[/tex]

b). V = 15 units

Step-by-step explanation:

Focal length F of a lens made by combining two lenses of different focal lengths U and V will be,

[tex]\frac{1}{F}=\frac{1}{U}+\frac{1}{V}[/tex]

A). By solving the given formula,

    [tex]\frac{1}{V}=\frac{1}{F}-\frac{1}{U}[/tex]

    [tex]\frac{1}{V}=\frac{U-F}{U.F}[/tex]

    [tex]V=\frac{U.F}{U-F}[/tex]

B). If F = 6 and U = 10 then we have to find the value of V.

    By substituting the given values in the formula,

    [tex]V=\frac{6\times 10}{10-6}[/tex]

    [tex]V=\frac{60}{4}[/tex]

    V = 15 units

    Therefore, focal length (V) of the lens = 15 units

Answer:

q = -7

Step-by-step explanation:

3 ^ -q * 1/27 = 81

Rewriting each as a power of 3

3 ^ -q *  3^ -3 = 3 ^4

We know that a^b * a^ c = a^ ( b+c)

3 ^ (-q -3) = 3 ^4

The bases are the same so the exponents are the same

-q-3 = 4

Add 3 to each side

-q-3+3 = 4+3

-q =7

Divide by -1

q = -7

Answer:

Maximum number of students=41

Step-by-step explanation:

Total allotted=£2500

Regular theatre Tickets=£45

1/5 off= 4/5*45

=£36

Train tickets=£20 each

Total cost per person=£36+£20

=£56

If 3 teachers and maximum number of students attend

Let x=maximum number of students

Therefore

£56(x+3) <or= £2500

56x+168 <or= 2500

56x <or= 2500-168

56x <or= 2332

x <or= 2332/56

x<or=41.643

Maximum number of students that will go on the trip=41 students

Total money left over for the school=

Total allotted - cost per person multiplied by number of teacher+students

=2500 - 56(3+41)

=2500-56(44)

=2500-2,464

=£36

Answer:

6 goes into 9 one time because 9-6=3 so there is 1 six in 9. Write 1 at the top because you have 1 6.

Subtract the 6 and you get 3

Bring the 6 from 96 down

you get 36

6 goes into 36 6 times because 36-6-6-6-6-6-6=0 so write a 6 at the top and you get 16 because of the previous 1.

Subtract 36 by 36 to get 0

Hope this helps

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

You have to take each number in the dividend (number being divided) and divide it by the number in the divisor (number that is dividing). Here you would take 9, the first number in the dividend and divide it by 6, and you would put that in the first space of the quotient (answer). You would then take that number and multiply it by 6 and place it in the space below. Subtract 6 from 9 and get 3. Drop down the 6 to get 36. Take 36 and divide that by the divisor 6 and get 6 next to the number 1 you calculated earlier to get your answer 16. Take 6 and multiply it back to get 36 and subtract it from 36 to get a remainder of 0.

Step-by-step explanation:

I guessed and got it right!

Answer:

Step-by-step explanation:

Given sinx< cos x and 0°< x < 90°, to get the possible value of x, we need to solve the given inequality for x.

sinx< cos x

Dividing both sides by cos x

sin x/cos x < cos x/cos x

tan x < 1

x < [tex]tan^{-1}1[/tex]

x < 45°

Since x is less than 45°, then one of the possible value of x can be 30° since 30° is less than 45° and 30° falls within the given range of values.
