find the zeros of f(x)= x⁴-2x³+10x²-18x+9, given a zero at x=1
Answer: f(1)=0
Step-by-step explanation:
replace x by 1
[tex]f(1)=1^{4}-2(1)^{3}+10(1)^{2}-18(1)+9[/tex]
f(1)= 1-2(1)+10(1)-18+9
f(1)= 1-2+10-18+9
f(1)= 1+10+9-2-18
f(1)= 20-20
f(1)= 0
The regular price of a baseball hat is 14.45$. If Carlos buys the baseball hat on sale for 20% off the regular price, how much change will he receive after paying with 20$
Answer:
$8.44
Step-by-step explanation:
To find the 20%
x/14.45=20/100
14.45×20=289
289÷100=2.89
We then subtract 2.89 from 14.45 to get the selling price.
14.45-2.89=11.56
$11.56 is the price of the baseball hat on sale.
To get the change
20-11.56=8.44
$8.44 is the change
I hope this helped! :)

Question 12 (1 point) Saved An angle measuring 28.3 radians is drawn in standard position? In what quadrant will the terminal side of this angle lie? Express your answer as a Roman numeral. I III IV
Answer:
Answer: III
Step-by-step explanation:
Quadrants
Given an angle in degrees, if its value is:
Between 0° and 90°, it lies in the first quadrant ( I )
Between 90° and 180°, it lies in the second quadrant ( II )
Between 180° and 270°, it lies in the third quadrant ( III )
Between 270° and 360°, it lies in the fourth quadrant ( IV )
We are given an angle of 28.3 radians. Converting to degrees:
[tex]28.3*180/\pi=1621^\circ[/tex]
To convert the angle to its standard position, we divide it by 360° and take the remainder:
1621/360 = 4 (integer part)
Remainder= 1621 - 4*360 = 181°
Since its value is between 180° and 270°, it lies in the third quadrant ( III )
Answer: III

Answer:
r = I/P*t
Step-by-step explanation:
So I dont know how to explain it but to show you how to do it.
I = Prt
Divide both sides by Pt to get r alone
[tex]\frac{I}{Pt} = r[/tex]

Mrs. Taylor wanted the chocolate ice cream. Ms. Pellegrino wanted the strawberry ice cream. While Mrs. Armstrong wanted the mint ice cream. They all knew that the cones had a diameter of 10 cm but they wanted to know the area of all of the ice creams combined. The total area of the ice cream is
_______cm2
Answer:
The surface area of each ice cream of the three ice cream is approximately 706.86 cm²
Step-by-step explanation:
The given parameters are;
The diameter of the cones = 10 cm
The radius of the cone, r = 5 cm
The assumption of the shape of the capping of the ice cream = Hemisphere
The surface area of an hemisphere = 3·π·r²
The surface area of each ice cream = 3 × π × (5 cm)² ≈ 235.62 cm²
The surface area of each ice cream of the three ice cream = 3 × 235.62 ≈ 706.86 cm²
The surface area of each ice cream of the three ice cream ≈ 706.86 cm².

The office manager of a small office ordered 180 packs of printer paper. Based on average daily use,
she knows that the paper will last about 40 days. How many packs of printer paper should the manager
expect to have after 35 days?
Answer:
22.5 packs of printer paper
Step-by-step explanation:
180/40 = 4.5
at a use of 4.5 per day over a period of 35 days, you have used 157.5
180-157.5 = 22.5
The number of packs of printer paper left after 35 days is given by the equation A = 27.5 packs of printing paper
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of packs of printer paper left after 35 days be A
Now , the equation will be
The total number of paper packs = 180 packs
The total number of days for the 180 packs of paper = 40 days
So , the number of packs of paper for 1 day = total number of paper packs / total number of days for the 180 packs of paper
Substituting the values in the equation , we get
The number of packs of paper for 1 day = 180 / 40
The number of packs of paper for 1 day = 4.5 paper packs a day
Now , the number of packs of paper for 35 days = 35 x number of packs of paper for 1 day
Substituting the values in the equation , we get
The number of packs of paper for 35 days = 35 x 4.5
The number of packs of paper for 35 days = 157.5 packs of paper
So , the number of packs of printer paper left after 35 days = total number of paper packs - number of packs of paper for 35 days
Substituting the values in the equation , we get
The number of packs of printer paper left after 35 days A = 180 - 157.5
The number of packs of printer paper left after 35 days A = 22.5 packs
Therefore , the value of A is 22.5 packs of paper
Hence , the number of packs of paper remaining is 22.5 packs

If PQR ≈ STU complete each part
Answer:
3 = 21 degrees
5 = 21 degrees
1 = 60 degrees
2 = 39 degrees
4 = 39 degrees
Step-by-step explanation:
This problem is really quite easy once you break it down. I assume you want an answer based on the attachment. If a triangle is Isosceles, then its bottom two angles are congruent, so angle 3 = angle 5.
Then, 138 degrees + x * 2 = 180 degrees.
x * 2 = 42 degrees
x = 21 degrees
So 3 and 5 are each 21 degrees
If a triangle is equilateral, then it is also equiangular, meaning each of its angles are equal to each other, and they are each 60 degrees. Then, we know angle 1 is 60 degrees. For 2 and 4, we want to take the measure of the combination of 2 and 3 (the full 60 degrees), and subtract it by the measure of angle 3 to get the measure of angle 2. 60 - 21 = 39 degrees. Angle 2 is 39 degrees. The same can be done with angle 5 and 4 because they are the same measurements.
2. What are the solutions to the quadratic equation
x? - 25 = 0
x = 5 and x = -5
x = 25 and x = -25
x = 125 and x = -125
no real solution
Answer:
The answer is x=5 and x=−5
x² - 25 = 0
(x-5)(x+5)=0
x²-5x+5x-25=0
x-5=0 x+5=0
x=5 or x=-5

hope it is correct.
Answer:
6!
Step-by-step explanation:
I'm not as sure about this answer, but I got it like this!
We know that a triangle adds up to 180. Two of our given measurements are 90 and 63. Adding those together we get 153. To solve for x, you'd have to subtract that from 180.
From there, you get 27! That's the answer to the equation, but not the value of x.
4 time 6 ( which is x) is 24, plus 3 is 27, so we know that x is 6!
I hope this helped, and made sense!!
