Find the discriminant of X^2+ 4x - 3 = 0
and determine the number of real
solutions of the equation.
Answer:
2 real solutions
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 ), then the discriminant is
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real and distinct solutions
• If b² - 4ac = 0 then 2 real and equal solutions
• If b² - 4ac < 0 then no real solutions
x² + 4x - 3 = 0 ← is in standard form
with a = 1, b = 4, c = - 3 , then
b² - 4ac = 4² - (4× 1 × - 3) = 16 - (- 12) = 16 + 12 = 28
Since b² - 4ac > 0 then the equation has 2 real and distinct solutions
find the measure of each angle if C D
Answer:
1=72 , 2=108 , 3= 72 , 4=108
Step-by-step explanation:
c parallel to d means that 108 and 1 are adjacent angles , sum 180
therefore ang 1 = 180-108=72
2=108, corresponding angles,
same as above for 3, angle 3= 180-108 =72
2 and 4 are vertically opposite and are equal.
A game decreased in price by 1/6
After the reduction it was priced at £75.
What was the original price of the game?
Answer:
Step-by-step explanation:
original price is x
Then the decreased price will be ' x - x/6'
= 5x/6
5x/6= 75
x= (75×6)/5
x= 90
original price = £90
Answer:
£90
Step-by-step explanation:
Since it was decreased by 1/6, it is 5/6 of the original price.
divide 75 by 5 to get 15.
15 is 1/6 of the price.
To get the full price, (6/6) multiply 15x6 and you will get 90.

Find the 11th term of the geometric sequence 6, -18, 54, ...
Answer:
354294
Step-by-step explanation:
Use the formula
[tex]a_{n} = a_{1} r^{n - 1}[/tex]
In your problem [tex]a_{1}[/tex] = 6 r = -3 n = 11
11th term = [tex]a_{11}[/tex] = [tex]6(-3)^{11 - 1} = 6(-3)^{10}[/tex] = 6(59049)
= 354294

When two objects reach the same time-space coordinates, they generally collide with each other. How is this different from what waves do?
Answer:
Waves superimpose upon each other when they collide, while objects do not
Step-by-step explanation:
The main difference between the collision of waves and the collision of objects is simply the superposition principle.
When waves collide, they do not do so in the same way objects do. The superposition principle explains that waves can either collide in a constructive or destructive manner.
Case A: Waves colliding in a constructive manner
When waves collide in a constructive manner, this means that they are in phase, in simpler terms, it means that they have the same shape as they move through space-time. Constructive collision leads to a formation of a bigger wave with a higher amplitude. This is how stereo speakers operate. They produce louder sounds by releasing the same audio waves, causing them to superimpose upon each other.
Case B: Waves colliding in a destructive manner:
When waves are out of phase(i.e do not have the same shape as they move through space-time) and they collide, they try to cancel each other out, leading to a new wave with a weaker amplitude. This is how noise-cancelling headphones work. They emit an equal and opposite wave sound to the noise around your ears, thus cancelling it out.
A circular patio has a radius of 4 yards. The patio is expanded so that the radius increases by 2 yards.
1) What is the area of the original patio? (blank)
Square yards
2) What is the area of the new patio? (blank)(
Square yards
3) By how many square yards does the area of the patio increase? (blank)
Square yards
Answer:
50.29 yards^2
113.14 yards^2
62.85 yards^2
Step-by-step explanation:
Area of a circle = πr²
π = pi = 22/7
r = radius
original area
(22/7) x 4² = 50.29 yards²
New area
radius = 4 + 2 = 6
(22/7) x 6² = 113.14 yards²
Increase in the area of the patio = 113.14 yards² - 50.29 yards²=62.85
Find the area of the shape shown below.

If someone wants to buy an item thats 4$ and a other item thats 14$ and a thrid item thats 6$ and they saved 10$ and he was given 1$ How much more money dose he need to buy all
Answer:
He needs $13 more to buy all.
Step-by-step explanation:
With the information provided, you have to add the prices of all the items and subtract the amount they saved and the amount he was giving to be able to know the money he still needs to buy all:
(4+14+6)-10-1=24-10-1=13
According to this, the answer is that he needs $13 more to buy all.

When Charlotte installed a fence along the 200 foot perimeter of her rectangular backyard, she left an opening for a gate. In the diagram below, she used x to represent the length, in feet, of the gate. What is the value of x
Answer:
x = 10
Step-by-step explanation:
P = 2(60 + x) + 2(30) = 200
= 120 + 2x + 60 = 200
2x + 180 = 200
2x = 20
x = 10
Henry had $22 and Ben had $17. Henry spent twice as much as Ben and was left with half as much as Ben. The amount of money that Ben spent is $____.
Answer:
Ben spent 9$
Step-by-step explanation:
Ben=x Henry=2x
17-x= 2(22-2x)
17-x=44-4x
-x+4x=44-17
3x=27
x=27/3
x=9 $ Ben spent

A triangle has an area of 6 square feet. The height is 4 feet. What is the length of the base in feet?
Answer:
3 feet
Step-by-step explanation:
[tex]\boxed{area \: of \: triangle = \frac{1}{2} \times base \times height}[/tex]
Given that the area is 6 ft² and the height is 4 ft,
6= ½ ×base ×4
Simplify:
2(base)= 6
Length of base
= 6 ÷2 (÷2 on both sides)
= 3 ft
what's the area of this shape
Answer:
L x W x H
Step-by-step explanation:
if my calculations are correct the length is 2 the width is 3 and the height is 3
Therefore the answer is (2 x 3) = 6 x3
So the answer is 18.
Hope it helps, if it is incorrect than i am extremely sorry, wish you the best of luck and have a great day/midday/evening. BYYEEEEEEE
