What are the zeros of the function g(x) = (x + 6) (x – 4)(x + 2) ?
9514 1404 393
Answer:
x in {-6, -2, 4}
Step-by-step explanation:
The zero product rule tells you that a product will be zero if and only if one of the factors is zero. These binomial factors are zero when x has a value that is opposite the constant of the binomial.
x +6 = 0 ⇒ x = -6
x -4 = 0 ⇒ x = 4
x +2 = 0 ⇒ x = -2
The zeros of the function are the x-values -6, -2, and 4.

On solving the equation n = za the value of a is obtained as a = n/z.
What is an equation?
A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").
To solve for a in the equation n = za, isolate a on one side of the equation.
Do this by dividing both sides by z:
n/z = (za) / z
On the right side, the z's cancel out, leaving -
n/z = a
So the solution is -
a = n/z
Therefore, the value of a that satisfies the equation n = za is equal to n divided by z.

how many numbers did bill wrote if he wrote all the natural numbers between w and v not including w and v
Answer:
v - w - 1
Step-by-step explanation:
Try an experiment with a small, specific set of numbers like:
4, 5, 6, 7, 8, 9, 10 w = 4 and v = 10.
There are 5 numbers in the list, not counting the first and last. Is this related to the difference between v and w? v - w = 6, one more than 5.
The number of natural numbers between w and v, not including w and v, is v - w - 1.

The amount of change that Tina got back would be = $10
How to calculate Tina's change after the bills payment?The amount of hours Tina spent in canoeing = 6 hours
The amount paid per hour for canoeing = $4
Therefore the total amount spent on canoeing = 6×4 = $24
The cost of the life jacket = $6
Therefore the total amount Tina spent = total amount spent on canoeing + cost of the life jacket.
That is; 24+6 = $30
The change Tina will receive from the two twenty dollars bills = (2×20) - 30
= 40-30 = $10

120 scarves to Shop A to sell
152 scarves to Shop B to sell.
Shop A sold 15% of its 120 scarves.
Shop B sold an eighth of its 152 scarves.
●
(b) Which shop sells the most scarves?
You must show your working.
Answer:
Shop B
Step-by-step explanation:
First, find the number of scarves that Shop A sold: 15% of 120 scarves is 15/100 * 120 scarves = 18 scarves.
Then, find the number of scarves that Shop B sold: an eighth of 152 scarves is 152/8 = 152/8 = 19 scarves.
Since 18 scarves is less than 19 scarves, Shop B sold more scarves.
(-5i)(7 + i)
Please help with with the correct response and explanation if you can I would be more than thankful for some help!
Answer:
To solve this problem, you need to use the distributive property, which states that for any two numbers a and b, and for any numbers x and y, (a + b) * x = ax + bx and x * (a + b) = xa + xb.
Applying the distributive property, we have:
(-5i)(7 + i) = (-5i) * 7 + (-5i) * i
= -35i + (-5i) * i
Now, you need to use the fact that i * i = -1:
(-5i)(7 + i) = -35i + (-5i) * i
= -35i + (-5) * (-1)
= -35i - 5
= -40i - 5
So the final result is -40i - 5.
Given the circle below with secants \overline{UVW} UVW and \overline{YXW} YXW . If YW=40, YX=16YW=40,YX=16 and VW=22VW=22, find the length of \overline{UV} UV . Round to the nearest tenth if necessary.
The length of UV in the circle is given as follows:
13.2.
How to obtain the length of UV?We are given two secant segments in the circle for this problem.
For two secants, the product of the lengths of one secant segment and it's external segment equals the product of the lengths of the other secant segment and it's external segment.
Hence, from the circle given by the image presented at the end of the answer, the relation for this problem is given as follows:
(22 + 17) x 17 = (20 + UV) x 20
Hence we must simply solve the expression to obtain the length of UV, as follows:
39 x 17 = 400 + 20UV
663 = 400 + 20 UV
20 UV = 263
UV = 263/20
UV = 13.2.

i am a 5 digit number,my ones place digit is of no use as i, i still remain same without it . my ten's and hundreds place digits are mirror images. my thousand place digit are half of 2nd, my 10thousand digit is 3 more than my ones place , who am i ?
Answer:
The 5 digit number is 34880
Step-by-step explanation:
Let the five digit number be represented by "abcde".
We are told that 1 place digit number is of no use and the 5 digit number will remain the same without it.
This means that e = 0
The tens and hundreds digit are d and c respectively. We are told that they are mirror images of each other.
Thus, d = c = 8. Since 8 is the only number from 1 to 10 that can be mirrored and still remain a usable number.
The thousand digit is Half of the second digit.
Thus, b = ½d
b = 8/2
b = 4
We are told the 10thousand digit is 3 more than my ones place. Thus;
a = e + 3
a = 0 + 3
a = 3
We have seen that;
a = 3
b = 4
c = 8
d = 8
e = 0
Thus,the 5 digit number is 34880

(b) Find the work (in ft-lb) done in winding up the cable when there is a 400- pound load attached to the end of the cable.
Answer:
4 pd / ft
140000 ft/pd
Step-by-step explanation:
Total Weight of cable = 800 pounds
Length of cable = 200 feets
Weight per foot = Total weight / length = 800 / 200 = 4 pounds per foot
Weight of piece will be :
Weight of cable - weight per foot * x
800 - 4x
Workdone with 300 pound load attached :
∫f(x)
f(x) = (800+300 - 4x) = 1100 - 4x
∫1100 - 4xdx at 200 to 0
Integrating the above
1100x - 4/2x² at x = 200 to 0
1100x - 2x²
1100(200) - 2(200²) - 1100(0) + 2(0^²))

The expression 10+(-8) is equivalent to 10 - 8.
What is expression?Different branches of mathematics exist. The branch of knowledge that deals with numbers and operations is arithmetic. We learned how to add, subtract, multiply, and divide two or more numbers through arithmetic.
Shapes and how they are created with various tools, such as a compass, ruler, and pencil, are the focus of geometry. Another fascinating area of study is algebra, which helps us communicate the numerical and alphabetic aspects of daily life (variables).
Any mathematical statement made up of numbers, variables, and an operation between them is called an expression or an algebraic expression. As an illustration, the expression 4m + 5 consists of the terms 4m and 5, as well as the variable m, all of which are separated from one another by the arithmetic sign +.

What expression is equivalent to 10-8?
Please help, I will mark you brainiest!
Answer:
20
Step-by-step explanation:
The line measures a total of 180°
So make an equation where all of the angles added together = 180
100 + 3x + x = 180
Then solve for x.
First, combine like terms.
100 + 4x = 180
Subtract 100 from both sides
4x = 80
Divide both sides by 4 to isolate x
x = 20

In ADEF, the measure of ZF=90°, DF = 40, ED = 41, and FE = 9. What ratio

E

9
D
40
Answer:
sec(∠F) = [tex]\frac{41}{9}[/tex]
Step-by-step explanation:
In triangle EFD,
m∠F = 90°
Adjacent side of ∠E = EF = 9 units
Opposite side of ∠E = DF = 40 units
Hypotenuse = DE = 41 units
For secant of ∠E ,
sec(∠E) = [tex]\frac{\text{Hypotenuse}}{\text{Adjacent side}}[/tex]
= [tex]\frac{41}{9}[/tex]
Therefore, [tex]\frac{41}{9}[/tex] is the ratio of secant of ∠F.
