Answer:
Step-by-step explanation:
Take 20 and 50.
20 * 50 = 1000.
We have the 2 zeros in 20 and 50 , also 2 * 5 = 10, making 3 zeroes.
write a quadratic polynomial, sum of whose zeroes is 2 and product is -8
Answer:
x^2 +2x-8
Step-by-step explanation:
Here, we want to write the quadratic polynomial given the sum of the root and the product
mathematically, we can have the factors as -2 And +4
So we have the equation as;
(x-2)(x + 4)
= x^2+ 2x - 8

Answer:
(4,2)
Step-by-step explanation:
Just by looking at the graph, you can see that they intersect at (4,2). But just to check:
x - 2 = -0.5x + 4
1.5x = 6
x = 4
y = 4 - 2 = 2

Answer:
m∠AYB = 85°
m∠C = 50°
Step-by-step explanation:
By is the angle bisector of ∠ABC,
Therefore, m∠1 = m∠2 = 30°
m∠3 = 35°
m∠AYB + m∠YAB + m∠ABY = 180°
m∠AYB = 180° - [(m∠1 + m∠2) + m∠3]
= 180° - [(30° + 30°) + 35°]
= 180° - 95°
= 85°
m∠A + m∠B + m∠C = 180°
2(30°) + 2(35)° + m∠C = 180°
60° + 70° + m∠C = 180°
m∠C = 180° - 130°
m∠C= 50°

Step-by-step explanation:
I believe this is right if it is wrong please tell me.
Answer:
16km
Step-by-step explanation:
Since its a right angle triangle we can use the pythogorean theorem, which is a^2 + b^2 = c^2
So if we apply it to this situation we get,
12^2 + b^2 = 20^2
144 + b^2 = 400
b^2= 400 - 144
b^2= 256
b= 16
So the answer is 16km
Hope this helped :)

Answer:
x ≈ 2.1
y ≈ 5.4
w = 5
Step-by-step explanation:
The given parameters are;
Segment AC = 13
Segment BC = y
Segment AD = 12
Segment CD = w
Segment BD = x
By Pythagoras's theorem, for the right triangle ΔACD, we have;
[tex]\overline {AC}[/tex]² = [tex]\overline {AD}[/tex]² + [tex]\overline {CD}[/tex]²
∴ 13² = 12² + w²
w² = 13² - 12² = 25
w = √(25) = 5
w = 5
By, Pythagoras's theorem similarly, in the right triangle ΔBCD we have;
y² = x² + w²
∴ y² = x² + 5² = x² + 25
y² = x² + 25
In the right triangle ΔABC we have;
[tex]\overline {AB}[/tex]² = [tex]\overline {AC}[/tex]² + [tex]\overline {CB}[/tex]²
∴ (12 + x)² = 13² + y² = 13² + (x² + 25)
(12 + x)² = 13² + (x² + 25)
144 + 24·x + x² = 13² + x² + 25
24·x = 13² + 25 - 144 = 50
x = 50/24 ≈ 2.1
x ≈ 2.1
y² = x² + 25
∴ y = √(x² + 25) = √((50/24)² + 25) = 65/12 ≈ 5.4
y ≈ 5.4

b) The cost price of an article was Rs 4000.Find the marked price of the
article so that there will be a profit of 20% after allowing a discount of
20%. show process
Answer:
Market price = Rs. 6,000
Step-by-step explanation:
Given:
Cost price = R.s 4,000
Profit after discount = 20%
Discount = 20%
Find:
Market price
Computation:
Sales price = Cost price[1+Profit after discount]
Sales price = 4,000[1+20%]
Sales price = 4,800
Market price = Sales price[100/(100 - Discount)]
Market price = 4,800[100/(100 - 20%)]
Market price = Rs. 6,000

What is the equation of the function shown in the table?
Input x -2 -1 0 1 2
Output y -3 -1 1 3 5
y = - 1/2 x - 1
y = 2x + 1
y = 2x - 2
y = -2x + 1
Answer:
y = 2x + 1
Step-by-step explanation:
According to the table:
+1 +1 +1 +1
[x] -2 -1 0 1 2
[y] -3 -1 1 3 5
+2 +2 +2 +2
y = mx + b
b is y when x = 0
m is the change in y divided by the change in m = ∆y/∆x or slope.
+2/+1 = 2 = m
y = 1 when x = 0 so b = 1
therefore y = 2x + 1

10. Find the width of the canyon.
13.
width = ?
22 m
15 m
160 m
I need help asap
Answer:
Therefore, the width of the canyon is 109.09 meters.
Step-by-step explanation:
* 160/22 = k (Scale Factor)
7.2727 = k
* Let x be the width of the canyon
x / 15 = k
x / 15 = 7.2727
x = 7.2727 (15)
x = 109.09 m
The width of the canyon is 109.09m.
The calculation is as follows:Here we assume x be the width of the canyon.
The k(Scale factor) should be
= [tex]160 \div 22[/tex]
k = 7.2727
So,
[tex]x \div 15 = k\\\\ x \div 15 = 7.2727[/tex]
x = 109.09 m

Your family is putting in a rectangular pool in the back yard. The pool's perimeter equals 28 feet. The contractor want the length to equal 5 more feet than 3 times the width. What will the width of your garden be?
Answer:
2.25 ft
Step-by-step explanation:
Perimter= 28ft
W= x ft
L= 3x+5
but
P=2L+2W
substitute
28=2*(3x+5)+2x
28=6x+10+2x
collet like terms
28=8x+10
28-10= 8x
18=8x
divide both sides by 8
x= 18/8
x=2.25 ft
Hence the width is 2.25 ft
