Answer:
15.87 m
Step-by-step explanation:
Length of ladder = hypotenus = 24 m
Height, opposite = 18m
Foot of ladder from the wall = x
Using Pythagoras rule :
Hypotenus² = opposite² + Adjacent²
x² = hypotenus² - opposite²
x² = 24² - 18²
x² = 576 - 324
x² = 252
x = √252
x = 15.87 m

The required equation of the line is y= 2x-5</h3><h3>
8.</h3><h3>
y=30</h3>
Step-by-step explanation:
Given , a line passes through the points (1,-3) and (3,1)
The equation of line which passes through the points and is
Here and
The required equation of the line is
8.
Given, y varies directly with x and y=24 when x=8
Therefore,
.........(1)
y = 24 when x=8
Equation (1) becomes
y= 3x
So, when x=10
y=3×10
⇒y=30
To find the 20 % down payment, you do the following:
767 * 0.2 = 154.4
Then you subtract this down payment from the total to get the remaining amount
767 - 154.4 = 613.6 which is the answer.
Answer:
Slope of the given function is 4.
Step-by-step explanation:
We have been given a function F(x) =4x+2
We will compare the given equation by general equation which is: y= mx+c where m is the slope of the line that is coefficient of x.
Here the coefficient of x in give function is 4 or m=4.
Hence, the slope of given function is 4.
