Answer:

sin x = cos y

Step-by-step explanation:

sin theta = opp / hyp

cos theta = adj / hyp

First find the hyp

a^2 + b^2 = c^2 from the Pythagorean theorem

5^2+12^2 = hyp^2

25+144= hyp^2

169= hyp^2

Taking the square root of each side

sqrt(169) =sqrt(hyp^2)

13= hyp

sin x = opp / hyp=5/13

sin y = 12/13

cos x = 12/13

cos y = 5/13

sin x = cos y

Haley is 41 years old. Haley is 15 years less than seven times Marcy's age. How old is Marcie
blondinia [14]
Harley is 15 years less than seven times Marcy's age, so that means Haley + 15 = 7 * Marcy

Equation: (41 + 15) / 7 = 56 / 7 = 8

Marcy's age is 8.

Hope this helped =)

The ages of three children in a family can be expressed as consecutive integers. The square of the age of the youngest child is
tensa zangetsu [6.8K]

Answer: 10, 11, & 12

<u>Step-by-step explanation:</u>

Let x represent the age of the youngest child.  

Their ages are consecutive so,

Youngest: x

Middle: x + 1

Oldest: x + 2

The age of the Youngest squared (x²) equals 8 times the Oldest [8(x + 2)] plus 4.

x² = 8(x + 2) + 4

x² = 8x + 16 + 4

x² = 8x + 20

x² - 8x - 20 = 0

(x - 10)(x + 2) = 0

x - 10 = 0     or      x + 2 = 0

  x = 10       or          x = -2

Since age cannot be negative, x = -2 is not valid

So, the Youngest (x) is 10

the Middle (x + 1) is 11

and the Oldest (x + 2) is 12

Pls work out and give detail. Use the slope formula to determine the slope of each line.
kolbaska11 [484]

Answer:

m=0

Step-by-step explanation:

Given

See attachment

Required

Determine the slope of the line

From the attachment, we have the following points

(x_1,y_1) = (-4,1)

and

(x_2,y_2) = (3,1)

The slope m is then calculated using:

m = \frac{y_2- y_1}{x_2 - x_1}

Substitute values for the x's and y's

m = \frac{1-1}{3 - (-4)}

m = \frac{1-1}{3 +4}

m = \frac{0}{7}

m=0

<em>Hence, the slope is 0</em>
