What is a quadratic function?A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.
Given:
A quadratic function,
f(x) = x²-4x-5.
To find the roots:
f(x) = x²-5x+ x -5.
f(x) = (x - 5) (x+ 1)
The roots are x = 5 and -1.
Therefore, the roots are x = 5 and -1.

Suppose there is a 1.1 drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 60.5, what will be the temperature when the plane reaches an altitude of 11,000?
Answer:
48.4° CStep-by-step explanation:
Step one:
We are told that there is 1.1° drop in temperature for each 1000 ft climb.
since the given altitude is 11,000ft,
hence there =(11000/1000)*1.1
= 11*1.1
=12.1°C drops in temperature.
Therefore, given that the temperature on the ground is 60.5° C
The temperature above is 60.5-12.1=48.4° C
The plane reaches an altitude of 11,000 is 48.4° C
The Mayflower started with 150 passengers. It lost 60% due to illness. How many people remained?
Answer:

Step-by-step explanation:
The triangle should equal 180 degrees. You already have 84+60= 144
Take that 144 with the equation of the other angle. 144-180 is 36
5x+1=36 subtract 1 from both sides
5x=35 divide by 5
x=7

A rope is 225 centimeters long.
You need the rope to be 1 1/2 meters long.
How many centimeters should you cut off?
Rope = 225 cm
Needed rope = 11/2m = (11/2) × 100 cm = 550cm
So, rope needed to be cut
= 550cm - 225cm
= 225cm
=225/100m
=2.25 m

6
please answer
Answer:
a = 6
Step-by-step explanation:
Given that (x - 2) is a factor of P(x) , then P(2) = 0 , that is
P(2) = 2² - 5(2) + a = 0 , so
4 - 10 + a = 0
- 6 + a = 0 ( add 6 to both sides )
a = 6

Devaughn is 13 years younger than Sydney. The sum of their ages is 79 . What is Sydney's age?
Answer:
26
Step-by-step explanation:
Let D =Devaughn's age
S= Sydney's age
So D+S=64
D=S+12
Now
D+S=64⇒D=64−S
and so
S+12=64−S 2S=52
S=26
Therefore
D=S+12
D=38

What is f(4) for the function f(x) = 6x +3?
f(4)=0
The value of function f(4) is 27.
It is required to find the value of function f(4).
What is function?
A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
Given that:
The function is
f(x) = 6x +3
Now put the value x=4 in the given function, we get
f(4)=6(4) +3
= 24+3
=27
f(4)=27.
Hence, the value of function f(4) is 27.

What is the volume of a hemisphere with a radius of 9.7 cm, rounded to the nearest tenth of a cubic centimeter? please i need help ill do a zoom call and i'll give you all my Branly points if uu help me.
Answer:
volume of hemisphere =1912.26cm^3
Step-by-step explanation:
radius(r)=9.7cm
now volume of hemisphere=(2/3)π[tex]r^{3}[/tex]
=(2/3)*(22/7)*(9.7)^3
=(2/3)*(22/7)*912.673
=(2/3)*2868.40086
=1912.26cm^3
The volume of a hemisphere is [tex]1910.52 cm^{3}[/tex].
What is volume of a hemisphere?
A hemisphere is half of a full sphere, we can calculate the volume of a hemisphere just by halving the volume of the complete sphere.
So, we can calculate the volume of a hemisphere by using the following formula,
[tex]$V=\frac{2}{3}\pi {{r}^{3}}$[/tex]
Here, [tex]r[/tex] is the radius, [tex]V[/tex] is the volume of hemisphere.
So,
It is given that the radius is [tex]9.7 cm[/tex].
We have to find [tex]V[/tex].
So,
[tex]$V=\frac{2}{3}\cdot 3.14\cdot {{\left( 9.7 \right)}^{3}}$[/tex]
[tex]V=1910.52[/tex]
Hence, the volume of hemisphere is [tex]$1910.52\text{ c}{{\text{m}}^{3}}$[/tex].
