A ladder is 12 metres long . It leans against a wall with one end on the ground 7 metres from the wall. The other end just reaches a windowsill. Calculate the height of the windowsill above the ground.
i need an explanation please...
Answer:
window sill height =9.75 meters
Step-by-step explanation:
Ladder^2=height^2+length^2
12^2=height^2+7^2
144=height^2+49
height^2=144-49=95
height=9.75

Can someone help me with 9,10, and 11 please you don’t have to do all of them just atleast one for me
Hi! So what you will need to know is pythagorean theorm.
What the theorm basically says is a^2 + b^2 = c^2.
-- The (a,b,c) are referring to the sides of the triangles (3 letters for 3 sides).
Take note that "c" is always the side opposite of the right angle.
The other known side could be "a" or "b"
Taking a look at problem 9, identify the "c" value. The "c" value would be 35.
Then indentify the value of "b" or "a". "a" would = 20.
Plug it into the equation:
20^2 + b^2 = 35^2
400 + b^2 = 1225
solve for b.
1. subtract 400 from both sides.
b^2 = 825
b = [tex]\sqrt{825}[/tex]
you could solve for the square root but it would give a decimal numbers but I'm not sure what the teacher is looking for.

Answer:
option (3)
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
(h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = x² - 12x + 7
Using the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² - 12x
f(x) = x² + 2(- 6)x + 36 - 36 + 7
= (x - 6)² - 29
with vertex (h, k ) = (6, - 29 )
Four positive whole numbers add up to 39 one of the numbers are a multiple of 7 the other three are equal workout the result when the four numbers are multiplied
Answer:
Number is 4536
Step-by-step explanation:
Assume;
Same number = a
Multiply of 7 = b
So,
a+a+a+b = 39
3a + b = 39
Use b = 7
3a + b = 39
3a + 7 = 39 (Not possible)
Use b = 14
3a + b = 39
3a + 14 = 39 (Not possible)
Use b = 21
3a + b = 39
3a + 21 = 39
a = 6
So,
Number is 6 x 6 x 6 x 21
Number is 4536

Find the value of x so that f(x)=3
Answer:
f(x) = (1/3)x - 2
f(x) = (1/3)(3) - 2
f(x) = 1 - 2 = -1
Step-by-step explanation:
f(x) usually refers to a function not a multiplication of two variables
find the length of side x in simplest radical form with a rational d enominator. 60 X 30
Answer:
x = [tex]\frac{ 7\sqrt{3} }{3}[/tex]
Step-by-step explanation:
7 = [tex]x\sqrt{3}[/tex]
x = [tex]\frac{7}{\sqrt{3}}[/tex]
multiply numerator and denominator by [tex]\sqrt{3}[/tex]
x = [tex]\frac{ 7\sqrt{3} }{3}[/tex]

3+{2×(8-4+6)}-5-{9+4-[3×(1-5)]}
Answer:
Step-by-step explanation:
Alright all we need to know is to understand our brackets
So 3+{2×(8-4+6)}-5-{9+4-[3×(1-5)]}
3+20-5-9+4-3(1-5)
Step 2
3+20-5-9+4-3(1-5) Simplify
18-9+4-3(1-5)
Step 3
18-9+4-3(1-5)
13-3(1-5)
13-(-12) Here is the tricky part (We aren't going to subtract because the brackets multiply the equations
So,
13+12=25

Answer:
11 1 /2 ( 11 and a half)
Step-by-step explanation:
If you noticed 7 and 2 are five numbers away.
To solve this I just added one to both of them until the sum was equal to 28.
If I had added one to 16 and 11, it would have given me 29, so I added a half.
That gave me 28.
What steps would you use to solve this equations for x? *
Answer:
x=-24
Step-by-step explanation:
Multiply both sides by 4 to get x=-24
[tex]\\ \rm\hookrightarrow -6=\dfrac{x}{4}[/tex]
Multiply 4 on both sides
[tex]\\ \rm\hookrightarrow x=-6(4)[/tex]
[tex]\\ \rm\hookrightarrow x=-24[/tex]

If g(x) = x^2-5, find the value(s) of x so that:
a. g(x)= 20
b. g(x) = 6
9514 1404 393
Answer:
a) x = ±5
b) x = ±√11 ≈ ±3.317
Step-by-step explanation:
Since we want x for some function value, it is convenient to determine the inverse function.
x = g(y)
x = y^2 -5
x +5 = y^2
y = ±√(x +5)
__
a) x = ±√(20 +5) = ±5
b) x = ±√(6 +5) = ±√11 ≈ ±3.317

Answer:
CD = 4
Step-by-step explanation:
I believe you know the geometric mean for altitudes?
CD = √AD * DB = √8 * 2 = √16 = 4
If you are not aware of this theorem, then use the similarity of triangles.
ADC ~ CDB
AD/DC = CD/DB (cross-multiply)
CD^2 = AD*DB,
CD = √AD * DB = √8 * 2 = √16 = 4
Tyrone went to a basketball game and bought a jersey that was on sale at a 30% discount. He also bought a hat that cost $37.89. Tyrone spent a total of $83.39. Write an equation to find the original cost of the jersey
Answer:
Jersey cost (without discount)= $65
Step-by-step explanation:
First, we need to determine how much he spent on the jersey:
Jersey cost (with discount)= 83.39 - 37.89
Jersey cost (with discount)= $45.5
Now, the original cost of the jersey:
Jersey cost (without discount)= discount cost / (1 - discount)
Jersey cost (without discount)= 45.5 / 0.7
Jersey cost (without discount)= $65

Round 72.178 to the nearest hundredth.
Answer:
72.18
Step-by-step explanation:
The hundreth place is the second to the right of the decimal. So the number in the hundreths place is 72.178. When rounding, you look at the number behind the number you are rounding to. In this case, you want to look at the 8. If the number is 5 or above, you round up. 8 is above 5 so you round the 7 to an 8.
Answer: 72.18
Step-by-step explanation:
hope this helps
