the height of a shed is 6cm. a ladder leans agaisnt the shed with its base 4.5 m away, and its top just reaching the roof. what is the length of the ladder?
Answers
Answer:
4.5m
Step-by-step explanation:
The set up is a right angles triangle
Height of the shed = opposite side = 6cm
Distance of the ladder from the shed = adjacent = 4.5m
Lenght of the ladder = Hypotenuse = x
Using pythegoras theorem to find the length of the ladder
hyp² = opp²+adj²
hyp² = 0.06² + 4.5²
hyp²= 0.0036+20.25
hyp² = 20.2536
hyp = √20.2536
hyp = 4.50m
Hence the length of the ladder is 4.5m

The fastest time for completing an obstacle course is 218 seconds. Artest completed the first half of the course in 95 seconds. It took him 124 seconds to finish the second half. a. What is Artest's total time? b. How does his time compare to the fastest time?
Answers
Answer:
219 Seconds ; He was 1 second faster
Step-by-step explanation:
Two halfs equal one whole, meaning both of the times added will equal the full time he took:
95+124=219
219 Seconds
He was 1 second faster because:
219-218=1

A shopkeeper purchased 100 blankets at Rs. 2000 each. He found that 10 blankets were
defective and he sold these at Rs. 1200 each. At what rate should he sell the remaining
blankets so as to gain 14% on the whole ?
Answers
Answer:
2,400.
Step-by-step explanation:
Since the shopkeeper bought 100 blankets at $ 2000 each, he spent a total of $ 200,000. He wants to make a total profit of 14% through his sale, that is, he wants to make sales for $ 228,000 (200,000 x 1.14).
Since he sold 10 defective blankets at $ 1200 each, he recovered a total of $ 12,000. Therefore, he has $ 216,000 (228,000 - 12,000) left to achieve his goal, through the sale of 90 blankets. Therefore, you must sell each blanket for $ 2,400 (216,000 / 90) to make the desired profit.

determine the value of p if one root of equation x^2+px+1=0 is the square of other.
Answers
Answer:
-2
Step-by-step explanation:
Given equation is x²+px+1=0
comparing the equation with ax²+bx+c=0
then a=1,b=p,c=1
let the roots one root of the equation be A then
by question, another root is A².
we know
A(ALPHA)+A²(beta)=-b/a
A+A²=-p/1
A+A²=-p......1
again
A*A²=c/a
A³=1/1
A³=1
A=1
Now,
substituting A=1 in equation 1
1+1²=-p
2=-p
Therefore p=-2.

What is the midpoint of the segment shown below?
Answers
Answer:
We conclude that the midpoint of the segment is:
[tex]\left(-\frac{9}{2},\:\frac{3}{2}\right)[/tex]Hence, option D is correct.
Step-by-step explanation:
Given the points
(-6, -1)(-3, 4)Finding the midpoint of the segment using the formula
[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-3,\:4\right),\:\left(x_2,\:y_2\right)=\left(-6,\:-1\right)[/tex]
so
[tex]=\left(\frac{-6-3}{2},\:\frac{-1+4}{2}\right)[/tex]
[tex]=\left(-\frac{9}{2},\:\frac{3}{2}\right)[/tex]
Therefore, we conclude that the midpoint of the segment is:
[tex]\left(-\frac{9}{2},\:\frac{3}{2}\right)[/tex]Hence, option D is correct.

This table models a linear function.
x -8 -4 4 8
y -1 0 2 3
Enter the coordinates of the y-intercept in the boxes.
Answers
Answer:
[tex](x,y) = (0,1)[/tex]
Step-by-step explanation:
Given
The above table
Required
Determine the coordinates of the y intercept
Represent points on the table as:
[tex](x_1,y_1) = (4,2)[/tex]
[tex](x_2,y_2) = (8,3)[/tex]
First, calculate slope (m):
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{3-2}{8 - 4}[/tex]
[tex]m = \frac{1}{4}[/tex]
For y intercept, the following coordinate point exist:
[tex](x_3,y_3) = (0,y)[/tex]
Because x = 0 at y intercept
Calculate the slope as:
[tex]m = \frac{y_3 - y_1}{x_3 - x_1}[/tex]
The equation becomes
[tex]\frac{1}{4} = \frac{y - 2}{0 - 4}[/tex]
[tex]\frac{1}{4} = \frac{y - 2}{- 4}[/tex]
Cross Multiply:
[tex]4(y-2) = -4 * 1[/tex]
Divide through by 4
[tex]y - 2 = -1 * 1[/tex]
[tex]y - 2 = -1[/tex]
Make y the subject:
[tex]y = 2-1[/tex]
[tex]y = 1[/tex]
Hence, the coordinates of the y intercept is:
[tex](x,y) = (0,1)[/tex]
