Answer:

The equation of line is y=-\frac{9}{4}x+12

Step-by-step explanation:

We have been given the equation of line as y=\frac{4}{9}x-2

Comparing this equation with the slope intercept form of a line y = mx+b , we get

m=\frac{4}{9}\\\\ b=-2

We know that the slopes of two perpendicular lines are negative reciprocal of each other.

Therefore, the slope of the required line is

m=-\frac{1}{4/9} =-\frac{9}{4}

Now, this line passes through the point (4,3)

Hence, using the point slope form of the line, the required equation is

y-y_1=m(x-x_1)\\\\y-3=-\frac{9}{4} (x-4)\\\\y=-\frac{9}{4}x+12

Therefore, the equation of line is

y=-\frac{9}{4}x+12

Y - y₁ = m(x - x₁)
 y - 3 = -2¹/₄(x - 4)
 y - 3 = -2¹/₄(x) + 2¹/₄(4)
 y - 3 = -2¹/₄x - 9
   + 3            + 3
       y = -2¹/₄x - 6

A decimal with a repeating digit of 0
natima [27]

Answer:

Necessarily it could be anything

Step-by-step explanation:

If you want a repeating decimal digit of 0 it's going to be all decimals just to a different place like the tenths place. For example 0.5 is also 0.500000000000... That is why pretty much every decimal has a repeating digit of 0.

Mhanifa please help :( no one has helped me on this yet
VMariaS [17]

Answer:

16)

  • q / 12 = sin 20
  • q = 12 sin 20
  • q = 4.1
  • p / 12 = cos 20
  • p = 112 cos 20
  • p = 11.3

17)

  • x / 44 = tan 39
  • x = 44 tan 39
  • x = 35.6
  • 35.6 / y = sin 39
  • y = 35.5 / sin 39
  • y = 56.4

18)

  • 14 / b = sin 57
  • b = 14 / sin 57
  • b = 16.7
  • a / 16.7 = cos 57
  • a = 16.7 cos 57
  • a = 9.1

How much money will there be in an account at the end of 10 years if $3000 is deposited at 3% interest compounded
BaLLatris [955]

Answer:

$4040.57

Step-by-step explanation:

A=P(1+(r/n))^nt

P = Principal = 3000

r = rate = 0.03

n = no. times payed each year = 2

t = years = 10

A = 3000(1 + (0.03/2))^(2x10)

A = 3000(1.015)^20

A = 4040.57 (2.d.p)

Hope this helped!
