2 percent of the students at Hamilton Middle School have red hair. There are 400 students at Hamilton Middle School. How many students at Hamilton Middle School have red hair?
Answer: There are 8 students at Hamilton Middle School with red hair.
Step-by-step explanation:
Given: The proportion of the students at Hamilton Middle School have red hair = 2% = 0.02
Total students in Hamilton Middle School = 400
Then , the number of students have red hair = (proportion of the students have red hair ) x (Total students )
= (0.02) x (400)
= 8
Hence, there are 8 students at Hamilton Middle School with red hair.
Answer:
Answer: There are 8 students at Hamilton Middle School with red hair.
Step-by-step explanation:
Given: The proportion of the students at Hamilton Middle School have red hair = 2% = 0.02
Total students in Hamilton Middle School = 400
Then , the number of students have red hair = (proportion of the students have red hair ) x (Total students )
= (0.02) x (400)
= 8
Hence, there are 8 students at Hamilton Middle School with red hair.

r(x) = -4x² + 5x1
r(-3) =?
Answer:
therefore when x = -3, r(x) = -51
Step-by-step explanation:
This is a function of r(x), so when it says r(-3), the x value is -3, so we have to find the value of r(x) when x=-3.
just plug in the x value in to the given equation
r(-3) = [tex]-4(-3)^{2}[/tex]+5(-3)
r(-3) = -4(9)+5(-3)
r(-3) = -36+-15
r(-3) = -51
therefore when x = -3, r(x) = -51
Answer: r(x) = -51
If the 1 is not a +1 or a -1
It is very unusual to have a 1 in that position.
Step-by-step explanation:
Substitute the value given (-3) in place of x, and evaluate the function.
r(-3) = -4(-3)² + 5(-3)
r(-3) = -4(9) - 15
r(-3) = -36 -15
r(-3) = -51

Paul creates the diagram to help him factor 4x2 + x – 5 by using double grouping. His diagram is incomplete.
Which terms should Paul write in squares M1 and M2?
a) 5x and −4x
b) –5x and 4x
c) –2x and 10x
d) 2x and −10x
Answer:
5x and -4x
Step-by-step explanation:
Because Paul is looking for M1 and M2 in order to get a total that is +x and a product that is equal to -20x^2, we can see that 5x and -4x help Paul get the products he wants.
Answer:
A; 5x and −4x

what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units.
Answer:
The equation for f(x)=|x| if it is what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units is f(x)=|x-3|-4
Step-by-step explanation:
We need to write equation for f(x)=|x| if it is what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units.
When the graph is shifted towards right h units the equation becomes f(x)=(x-h) using it for our scenario:
If x is shifted right 3 units it will become f(x)=|x-3|
When the graph is shifted down h units the equation becomes f(x)=x-h using it for our scenario:
and Shifted down 4 units the equation will become: f(x)=|x-3|-4
So, the equation for f(x)=|x| if it is what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units is f(x)=|x-3|-4

at midnight the temperature in alto is -3.8 the wind chill makes the temperature feel 5.6 colder then the actual temperature what is the wind-chill temperature
Answer:
-5.6
Step-by-step explanation:
Given parameters:
Temperature at Alto = -3.8°C
Unknown:
The wind chill temperature = ?
Solution:
Due to the windchill, temperature in Alto feels colder at -3.8.
We can infer that usually, the temperature in Alto is not supposed to be up to this value. The windchill reduced the temperature;
Temperature in Alto = Original temperature + wind chill temperature
Originally, the temperature would be = -3.8 + 5.6 = 1.8
So;
-3.8 = 1.8 + wind chill temperature
Wind chill temperature = -3.8 - 1.8 = -5.6
Answer:
-9.4

How do I find the missing sides on this special triangle?
Answer:
x = 6
y = [tex]3\sqrt{2}[/tex]
Step-by-step explanation:
Thats a 45 45 90 triangle, one of my favorite and you'll come to miss it later because of how easy it is.
See the file provided for the trick
Because [tex]3\sqrt{2}[/tex] falls where a 1 is in the diagram that means y is also [tex]3\sqrt{2}[/tex] because you multiply [tex]3\sqrt{2}[/tex] by 1, and to get x you'll multiply the value we're given, [tex]3\sqrt{2}[/tex], by the value in the spot in the given diagram, [tex]\sqrt{2}[/tex].
[tex]3\sqrt{2}[/tex] ×[tex]\sqrt{2}[/tex]
Note; a radical multiplied by itself is the value in the radical
Therefore,
[tex]3\sqrt{2}[/tex] ×[tex]\sqrt{2}[/tex] = 3(2) = 6
Thus x = 6
The explanation for this;
[tex]\sqrt{2}[/tex] * [tex]\sqrt{2}[/tex] = [tex]\sqrt{2}^2[/tex]
And if you square a square root you have its square root times its square root squared, which if it was [tex]\sqrt{4}^2[/tex] it'd ultimately be [tex](2)^2[/tex] which is 2x2 which equals 4
Hope this helps
A line that passes through the points (−5, 7) (10, 1). Using the mx+b format
Answer:
y=2x-19
Step-by-step explanation:
I'm guessing you mean slope intercept form y=mx+b
If so, first you would have to find the slope of the line
To do that, use the formula y2-y1/x2-x1
Remember you can pick any coordinate pair for this
I will pick 1=y2 -5=y1 10=x2 and 7=x1
When I put that in the equation I get 1-(-5)/10-7
Overall I get 6/3, or 2
Now to find the y intercept, you plug in the slope and one of the coordinates(any is fine)
I will pick (10,1)
1=y and 10=x and 2=m
1=2(10)+b
this simplifies to 1=20+b
now subtract 20 from both sides and get -19 = b
Now you have your equation y=2x-19

Which function has a domain of all real numbers?
A. y=-x½+5 B. y=(2x)⅓-7 C. y=(x+2)¼ D. y=-2(3x)⅙?
Answer:
B.
Step-by-step explanation:
B. Because the others have exponents whose denominators are even so the results of , for example x^1/2, if x is negative is not defined.
For example:
For A, when x is -4, (-4)^1/2 is not real.
For B, when x = -4, (2*-4)^ 1/3 = -8^(1/3) = = -2.
