Answer:
m∠PNO = 60°
m∠O = 33°
Step-by-step explanation:
∡NPO is 87° because it's a vertical angle with the 87° angle
3) ∡PNO is supplementary to the 120° angle (they must add to 180°)
4) m∠O = 180 - (60 + 87) = 33

. Which of the following is a zero of the polynomial f(x)= x5+2x4+x+2?
A. I
B.-1
C.-2
D. 2
Answers
Answer:
x = -2 is a function
Step-by-step explanation:
To get which is a zero, we have to look at one value of x which when substituted into the polynomial will give -1
we have this as:
Let us try the value x = -2
-2^5 + 2(-2)^4 - 2 + 2
= -32 + 32 - 2 + 2 = 0
This means that the term x = -2 is a root of the equation

Alaina needs to sell 225 boxes in order to be the top seller. She sells thin mints and samoas to all of her customers for a total of $628.00 in sales. The thin mints sell for $3.00 each and the samoas sell for $2.50 each. Which system of equations below could be used to find how many boxes of thin mints and samoas were sold?
Answers
Answer:
94 boxes of samoas
131 boxes of thin mints
Step-by-step explanation:
m=mints
s=samoas
s+m=225 m=225-s
s(2.5)+m(3)=628
2.5s+3m=628
substitute for m
2.5s+3(225-s)=628
2.5s+675-3s=628
reduce
-0.5s=-47
s=94
m=131
In a survey of U.S. Adults, 16% say they have had someone take over their email accounts without their permission. You randomly select 250 U.S. Adults and asked them whether they have had someone take over their email accounts without their permission. Find the probability that the number of U.S. Adults who say they have had someone take over their email accounts without their permission is : a. At most 40 b. Less than 45 c. Exactly 48
Answers
Answer:
a. At most 40
Step-by-step explanation:
If we take the survey that was done as a basis then we would use the 16% that was obtained as the number of overall US adults that have had their accounts used without their permission. Assuming that the 250 selected individuals were selected at random and without bias then those 250 would also be representative of the entire population. Therefore, we would simply need to multiply the number of selected individuals by the percentage in decimal form.
16 / 100 = 0.16
250 * 0.16 = 40
Finally, we can see that roughly 40 individuals would have had their email used without permission.

can someone plz help me
Answers
Answer:
x is less than or equal to negative 14.
Step-by-step explanation:
so for now we should pretend that the greater than or equal to is an equal sign, and simplify the problem to get x alone on a side
remove 5 from each side
-x/3=1/3-5
-x/3=14/3
multiply both sides by 3
-x=14
x=-14
so we can now replace the equal sign with the equal or greater to, so x is less than or equal to -14

A tree grows 2 inches per year. It was 14 inches tall when it was planted. what would be this function discrete continuous or neither? whould it be a linear an exponential or neither? what would be the domain?
please help greatly appreciated
Answers
Answer:
This function is a continuous linear function that's domain is all positive real numbers.
Step-by-step explanation:
This function is continuous because every linear function is continuous and this function is the linear function y = 2x+14 where x is the years it has been planted and y is the height.
It is a linear function, it's hard to explain, but it has a dependent variable, the height of the tree that changes at a constant rate with the independent variable which is time in years.
The domain is all positive real numbers since time/years can not be negative.

z is 95 degrees.
Step-by-step explanation:
Linear angle pairs make 180 degrees. Since ∠ABC is a straight line, it is 180 degrees. And since ∠ABD and ∠DBC are on that line, they are a linear angle pair. You just need to find out what number + 85 degrees would = 180 degrees, which in this case, is 95.

Answers
Firstly the best thing to do is create two different equations.
1. y=25+.08x
2. y=20+.12x
Then you plug into Desmos and see at what point they cross. They cross at (125, 35).
Therefore for 125 text messages would cost 35$ for each plan.

Find the area of the base of a box of height 4cm and lateral surface area 120cm.sq if its length is twice its breadth.
Answers
Answer:
The area of the base of a box is 1800 cm².
Step-by-step explanation:
We have:
H: is the height = 4 cm
[tex]A_{l}[/tex]: is the lateral surface area = 120 cm
L = 2B
We can find the breadth of the base by using the lateral surface area and the height:
[tex] A_{l} = H*B [/tex]
[tex] B = \frac{A}{H} = \frac{120 cm}{4 cm} = 30 cm [/tex]
Now, if the length is twice its breadth we have:
[tex] L = 2B = 2*30 cm = 60 cm [/tex]
Hence, the area of the base is:
[tex] A_{b} = B*L = 60 cm*30 cm = 1800 cm^{2} [/tex]
Therefore, the area of the base of a box is 1800 cm².
