Find the equation of the line perpendicular to the 13x-3y=9 and passing through (-5,0)

Answer:

Below

Step-by-step explanation:

You can use this formula to find the sum of an arithmetic series

     Sn = n / 2 (a1 + an)

You need to find the number of terms in each series before using the formula

     Tn = a + (n - 1) d

a) 53 = 5 + (n - 1) 3

      n = 17

Sn = 17 / 2 (5 + 53)

    = 493

b) 98 = 7 + (n - 1) 7

      n = 14

Sn = 14 / 2 (7 + 98)

   = 735

c) -102 = 8 + (n - 1) -5

        n = 23

Sn = 23 / 2 (8 + (-102))

   = - 1081

d) 41/3 = 2/3 + (n - 1) 1

        n = 14

Sn = 14 / 2 (2/3 + 41/3)

    = 301 / 3 or 100 1/3

Answer:

3780

Step-by-step explanation:

84 = 2^2 * 3 * 7

27 = 3^3

35 = 5 * 7

45 = 3^2 * 5

lcm = 2^2 * 3^3 * 5 * 7 = 3780

Answer:

Step-by-step explanation:

diagonal  = 32 cm

Area of square = [tex]\dfrac{d^{2}}{2}[/tex]

                        [tex]=\dfrac{32*32}{2}\\\\=512 \ cm^{2}[/tex]

Diagonal separate the square into two equal triangles.

Area of upper triangle that is shaded black = area of lower triangle = 512/2

= 256 cm²

Isosceles triangle:

a = 6 cm  ; b = 6 cm c = 8cm

[tex]s = \dfrac{a+b+c}{2}\\\\=\dfrac{6+6+8}{2}\\\\=\dfrac{20}{2}\\\\=10\\\\s-a = 10 - 6 = 4 \ cm\\\\s-b = 10-6 = 4 \ cm\\\\c - c = 10 - 8 = 2 \ cm\\\\Area = \sqrt{s*(s-a)(s-b)(s-c)}\\\\=\sqrt{10*4*4*2}\\\\=\sqrt{2 * 2 * 4 * 4 * 5}\\\\=4*2\sqrt{5}\\\\=8\sqrt{5}\\\\=8*2.24\\\\=17.92 \ cm^{2}[/tex]

Area of black shade paper = 256 + 17.92 =  273.92 cm²

Area of white shade paper = 256 cm²

Area of the isosceles triangle = s(s-a)(s-b)(s-c)

Answer:

1/2(x + y)

Step-by-step explanation:

The sum of x and y is  x + y

1/2 the sum of x + y is 1/2(x + y)

1/2 x^3

This is subtracted from y

y - 1/2 x^3

Answer:

2x

Step-by-step explanation:

I'm going to guess that the diagram means that you have 4*(+x) and you subtract 2(x) leaving you with 2x

The ones are a bit harder

(6*1) + (6*-1) = 0

Answer:

a=5 and b=9

Step-by-step explanation:

(x, y) = (s, t) => x=s and y=t

Hence, a+3=b-1 and b-2=2a-3, solving we get a=5 and b=9

Answer:

7

Step-by-step explanation:

Sumita uses 30g sultanas for 14 so we have 30:2 =15 => 14:2=7

[tex] \frac{6a - {b}^{2} }{2} + \binom{b}{a} ^{2} [/tex]

a=2 b=4

[tex] \frac{6(2) - {4}^{2} }{2} + \binom{4}{2}^{2} [/tex]

[tex] \frac{12 - 16}{2} + \frac{16}{4} [/tex]

Answer:

0

Step-by-step explanation:

To find the slope, we can use the slope formula

m = (y2-y1)/(x2-x1)

    = (0-0)/(4- -10)

    = (0-0)/(4+10)

    = 0/14

   =0

Answer:

160 cm²

Step-by-step explanation:

If the two rectangles are similar, that means they have equal scale factors.  The smaller rectangle has length of 8 cm and area of 40 cm, which means the width is 5 cm.  

The width of the larger rectangle is 10 cm, which is double the width of the smaller, similar rectangle.  So, to find the length of the larger rectangle, multiply 8 x 2, which gives you 16 cm for the length, since the scale factor is 2.

Now, just find the area of the larger rectangle by doing length x width.  16cm x 10 cm = 160 cm²

Answer:

160 cm^2

Step-by-step explanation:

Our strategy is to find the length of the larger rectangle so we can find the area. To find the length, we will rely on the fact the two rectangles are "similar": their sides are in equal proportions, or have the same "ratio."

We know that the smaller rectangle has a width of 5 cm because, when we substitute area and length into

A = lw

we get

40 = 8w

w = 5

when we divide both sides by 8.

Because of equal proportions:

Width : length of the smaller rectangle = Width : length of the larger rectangle

We can write an equation

5 / 8 = 10 / x

Cross multiply

5x = 80

x = 16

So the larger rectangle has a length of 16 cm and a width of 10 cm (given)

meaning the area is

16 * 10 = 160 cm^2

Answer:

2

Step-by-step explanation:

Answer:

17

Step-by-step explanation:

Evaluate the 2 expressions by substituting x = 2 , y = 3 into them

3x² - 2y

= 3(2)² - 2(3)

= 3(4) - 6

= 12 - 6

= 6

---------------------------

3y² - 2x

= 3(3)² - 2(2)

= 3(9) - 4

= 27 - 4

= 23

Then 23 - 6 = 17

Answer:

Factors of 15: 1, 3, 5 and 15.

Factors of 17: 1 and 17.

Factors of 26: 1, 2, 13 and 26

Factors of 80: 1, 2, 4, 8, 10, 20, 40, and 80.
