To determine if it's has a solution in R, let's calculate Δ
Δ = (4)² - 4 * (1) *(-3)
Δ = 16 +12
Δ= 28
as Δ≥ 0 so the function allow two solution within R
so S 1 = ( -4 +√28) / 2 S 2 = (-4 -√28 ) /2
S1 = ( -4 + 2√7) /2 S2 = (-4 - 2√7) /2
S1 = (2 (-2 +√7) /2 S2 2 (-2 -√7) /2
S1 = -2 +√7 S2 = -2 -√7
So the two function are equal twice. one for x = -2 +√7 and second x = -2-√7

if a football is thrown upward, its height above the
ground is given by the equation s=-16t^2+Vot+so, where
Vo and so are the initial velocity and intial height of the
Football, respectively, and t is the time in seconds.suppose
the football is thrown from the top of a building that is
192 feet tall, with an initiae speed of 96 feet per second.
a)write the polynomial that gives the height of the Football in terms
of the variable t (time)
b) what is the height of the Football after 2 seconds have
Clapsed? Will the football hit the ground after 2 seconds?
Answers
Answer:
a) s = -16[tex]t^{2}[/tex] + 192t + 96
b) Height of the football after 2 seconds is 448 feet.
ii. The football would not hit the ground after 2 seconds.
Step-by-step explanation:
Given:
s = -16[tex]t^{2}[/tex] + [tex]V_{o}[/tex]t + [tex]s_{o}[/tex]
where: s is the height of the football above the ground, t is the time, [tex]V_{o}[/tex] is the initial velocity and [tex]s_{o}[/tex] is the initial height.
The height of the building = [tex]V_{o}[/tex] = 192 feet and the initial speed of the ball = [tex]s_{o}[/tex] = 96 feet per second, then;
s = -16[tex]t^{2}[/tex] + 192t + 96
a) The polynomial is given as:
s = -16[tex]t^{2}[/tex] + 192t + 96
b) The height of the football when t = 2 seconds is;
s = -16(2) + 192(2) + 96
= -32 + 384 + 96
= -32 + 480
s = 448
The height of the football when t = 2 seconds is 448 feet.
ii. The football would not hit the ground after 2 seconds.

Answer:

Step-by-step explanation:
Here, we want to pick the appropriate conversion from percentage to fraction:
To convert from percentage to fraction, we simply divide by 100
125% = 125/100 = 1.25 correct
30% = 30/100 = 0.3 not 0.03 wrong
1% = 1/100 = 0.01 not 0.001 wrong
60% = 60/100 = 3/5 correct
50% = 50/100 = 1/2 not 1/4 wrong
2/3 = 2/3 * 100 = 200/3 = 66.66667% correct

Each week mrs endo bikes 0.86 mile to the garden. Then she bikes 2.3 miles along the river back home. About how many miles will mrs endo bike in a year?
Answers
Answer: 164.32 miles
Step-by-step explanation:
Given that:
Weekly coverage :
Miles biked to the river = 0.86 miles
Miles biked along the river back home =. 2.3 miles
Total miles biked weekly:
(0.86 + 2.3) miles = 3.16 miles weekly
Number of weeks per year = 52
Miles biked yearly : (number of weeks per year * miles biked weekly)
= 52 * 3.16 miles
= 164.32 miles
Mrs endo will bike about 164.32 miles in a year.

Answers
Answer:
a is 6 sq ft, b is 15 sq ft
Step-by-step explanation:
I'm going to call the bottom triangle (the one with 3, and 4 as its side lenght), and the top one, b.
So a is 3 times 4/2=12/2=6 sq ft.
b is 6 times 5/2=30/2=15
Answer:
21 ft²
Step-by-step explanation:
A = [tex]A_{1}[/tex] + [tex]A_{2}[/tex]
[tex]A_{1}[/tex] = (5 × 6) ÷ 2 = 15 ft²
[tex]A_{2}[/tex] = (4 × 3) ÷ 2 = 6 ft²
A = 15 + 6 = 21 ft²

A pair of $36 jeans were on sale at Jim's Jeans for 1/3 off. The same pair of jeans were $42 at David's Denims. The jeans were on sale for 2/3 off.
Answers
Complete question :
A pair of $36 jeans were on sale at Jim's Jeans for 1/3 off. The same pair of jeans were $42 at David's Denims. The jeans were on sale for 2/3 off.
A.) which store had the better buy
B.) how much will you pay at the store that has the better buy
Answer:
A.)David's denim has the better buy
B.) $14
Step-by-step explanation:
Jim's Jean store :
Cost of Jean = $36
Discount = 1/3 off
Discounted cost = $36 - (1/3 * $36)
Discounted cost = $36 - $12 = $24
David's Denim:
Cost of Jean = $42
Discount = 2/3 off
Discounted cost = $42 - (2/3 * $42)
Discounted cost = $42 - $28 = $14
David's denim has the better buy with a discounted price lower than the discounted price at Jim's store.
Cost at store with the better buy is $14

Step-by-step explanation:
C
The change of the frequency of people waking up with respect to the sound level, 9% per 8 decibels.
What is linear function?Linear function is the function in which the highest power of the unknown variable is one. Linear functions used to model the real life problem in the mathematical expressions.
The linear function with dependent variable y and independent variable x can be written as,
[tex]y=mx +c[/tex]
Here, (m) is the slope of the function and (c) is the y intercept.
The slope can be found out as,
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The sound level is plotted on x-axis and frequency of people walking up (%) is plotted on y-axis. The slope of the line given the rate of change of y values with respect to x value.
In the graph given, the frequency of people walking up is 10 at 55 decibels and 55 at 95 decibels. The point, we get for this line are (55, 10) and (95, 55). Therefore the slope or the change of rate is,
[tex]\dfrac{dy}{dx}=\dfrac{55-10}{95-55}\\\dfrac{dy}{dx}=\dfrac{45}{40}\\\dfrac{dy}{dx}=\dfrac{9}{8}[/tex]
Hence, the change of the frequency of people waking up with respect to the sound level, 9% per 8 decibels.

Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-11-(7*(1-2*f)+5)=0
-11 - (7 • (1 - 2f) + 5) = 0
14f - 23 = 0
3.1 Solve : 14f-23 = 0
Add 23 to both sides of the equation :
14f = 23
Divide both sides of the equation by 14:
f = 23/14 = 1.643
