Paul is locked out of his house. An 18-ft ladder is outside and an upstairs window is open. Paul read the safety warning on the ladder recommending it be placed six feet away from the wall. He placed the ladder according to the warning and it reached the base of the window. How high is the base of the window off the ground?
Answer:
17.0 ft
Step-by-step explanation:
Let h be the height of the base of the window from the ground, L be the length of the ladder = 18 ft and d be the distance of the ladder from the wall = 6 ft. Now, these three lengths form a right-angled triangle with the length of the ladder, L as the hypotenuse side.
So, using Pythagoras' theorem,
L² = h² + d²
So, h = √(L² - d²)
Substituting the values of L = 18 ft and d = 6 ft, we have
h = √((18 ft)² - (6 ft)²)
= √(324 ft² - 36 ft²)
= √288 ft²
= 16.97 ft
≅ 17.0 ft

-3/8(x-24)+x=19 i need a answer ASAP!
Answer:
x = 16
Step-by-step explanation:
Problem: -3/8(x-24)+x=19
Distribution:
-3/8x + 9 + x = 19
5/8x = 19 - 9
5/8x = 10
x = 10 • 8/5
x = 16

Answer:
3.375
Step-by-step explanation:First convert the 2 1/4 and the 1 5/8
then you just add it with the 0.5 or just use a calculator
2 1/4 = 9/4
1 5/8= 13/8
okay now do this ---> 0.5 + 9/4 +13/8 =3.375

The lengths of the two legs of a right triangle are 4 and 7. What is the length of the
hypotenuse? Express answer in Simplified Radical Form.
Answer:8.06
Step-by-step explanation:
4 x 4= 16 7 x 7 = 49
49+16=65
square root of 65 =8.06
Answer:
[tex] \sqrt{65} [/tex]
Step-by-step explanation:
To find the hypotenuese of a right angle you use the pythagreon theroem.
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
a and b are the height and base, while c is the hypotenuese. simply insert the values in the equation and find the variable.
[tex] {4}^{2} + {7}^{2} = {c}^{2} \\ 16 + 49 = {c}^{2} \\ 65 = {c}^{2} \\ \sqrt{65} = c[/tex]
The radical form answer is above, otherwise it would be a decimal.

Step-by-step explanation:
write the equation of the line, in standard form, that is perpendicular to y=3x-2 and passes through (-7,2)
Answer:
x+3y=-1
Step-by-step explanation:
y=3x-2 so m=3 old slope
the new slope must be -1/3 (opposite reciprocal of the old slope).
y-y0=m*(x-x0)
y-2=-1/3*(x-(-7))
y-2=-1/3x-1/3*7
y-2=-1/3x-7/3
3y-6=-x-7
The standard form for linear equations in two variables is Ax+By=C.
x+3y=6-7
x+3y=-1
state the equation of the line in y = mx + b form.
