A 10-foot ladder leans against a wall with its foot braced 3 feet from wall's base. How far up the wall does the ladder reach?
dlinn [17]
Pythagorean theorem
for a right triangle with legs legnth a and b and hytponuse c
a^2+b^2=c^2

the legnht of th eladder is the hypotnuse
the 3 feet is bottom leg
height is other leg

10=c
3=a
b=?
3^2+b^2=10^2
9+b^2=100
minus 9 both sides
b^2=91
sqrt both sides
b=√91
aprox
b=9.53939


answer is √91 feet or aprox 9.53939

Find the domain of <br> - y/(y-6) +15/(y+6)<br> - y-10/y^2+3
ArbitrLikvidat [17]

Answer:

Step-by-step explanation:

Domain of a function represents the set of x-values (input values) and y-values (output values) of the function represent the Range of the function.

Given function is,

If Domain (input values) of this function is,

{-12, -6, 3, 15}

Table for the input-output values of this function,

x        -6         3        15       -12

y        11         5         -3        15

Mr. Drysdale earned 906.25 in interest in one year on money that he had deposited in
VikaD [51]

Answer: Mr Drysdale deposited 14,500

Step-by-step explanation:

Using the simple Interest formula

Simple Interest = Principal(Initial Money) * Interest Rate * Time Period

I = P*R*T

I = PRT

To get P which is the initial money he deposited, we divide both sides by RT

I/RT = PRT/RT

I/RT = P

Therefore the money deposited

P = I/RT

Interest (I)= 906.25

Interest Rate (R)= 6.25% = { converting percentage to decimal} (6.25/100)= 0.0625

Time Period (T) = 1 year

Principal (P)= ?

P= I/RT

P= 906.25/(0.0625 * 1)

P= 906.25/0.0625

P= 1450

The money he deposited in his local bank is 14,500

What is the y-intercept of the line passing through the point 5, -6 with a slope of -1 over 7
morpeh [17]

Answer:

  • The y-intercept is (0, -37/7).

Explanation:

When you have one point and the slope of a line you can find its equation by using the point-slope form of the linear function:

  • m = slope
  • point = (a, b)
  • point-slope equation: (y - b) = m (x - a).

Now substitute m = -1/7 and (a,b) = (5, - 6)

  • y - (-6) = -1/7 (x - 5)

Solve for y:

  • y + 6 = - 1/7 ( x - 5)
  • 7y + 7(6) = - (x - 5)
  • 7y + 42 = - x + 5
  • 7y = - x + 5 - 42
  • 7y = - x - 37
  • y = -(1/7)x - 37/7 ← this is the slope-intercept form of the equation.

The y-intercept is the point when x = 0. So, the corresponding y-coordinate is the constant term in the last equation:

  • y = 0 - 37/7 = - 37/7

And the y-intercept is the point (0, -37/7).
