Answer:
Step-by-step explanation:
To find the zeros of this polynomial, set the polynomial equal to zero, and then set each of the factors equal to zero separately. Solve each equation for x:
x - 1 = 0 yields x = 1. The x-intercept is (1, 0).
x + 3 = 0 yields x = -3. The x-intercept is (-3, 0).
2x + 1 = 0 yields x = -1/2 The x-intercept is (-1/2, 0)
Answer:
(- 3, 0), (- 1/2, 0), (1, 0)
Step-by-step explanation:
p(x)=(x-1)(x+3)(2x+1)
Plug p(x) = 0
Therefore,
(x-1)(x+3)(2x+1) = 0
x - 1 = 0 or x + 3 = 0 or 2x + 1 = 0
x = 1 or x = - 3 or x = - 1/2
Hence, (- 3, 0), (- 1/2, 0), (1, 0) are zeroes of the given polynomial
Heather made $209 for 11 hours of work.
At the same rate, how many hours would she have to work to make $171?
Answer:
9 hours

To get from 19 to 171 multiply by 9.
9 hours: 171 dollars.
She has to work 9 hours.
I hope this helps :)
Answer:
9 hours
Step-by-step explanation:
rate: $209/h11 = $19 per 1 hour

expression [12]? No links or it will be reported and explain your answer please.
A -12
B |-12
Answer:
Option C
Step-by-step explanation:
The absolute value or modulus of a real number x ( denoted by |x| ), is the non-negative value of x without regard to its sign.
Absolute value of 12 = | 12 | = 12
Also , absolute value of -12 = | -12 | = 12
Hence , the correct option is C.

Home Depot is delivering washing machines to buyers. The washing machines are rectangular prisms that measure 5 ft x 5 ft x 6 ft. These machines are then packed into a delivery truck with dimensions of 30 ft x 15 ft x 12½ ft.
What is the volume of the delivery truck? please show work
How many washing machines can be packed into the delivery truck? show work please
Answer:
37.5
Step-by-step explanation:
Volume of the washing machine = 5 ft x 5 ft x 6 ft
= 150 ft³
Volume of the delivery truck = 30 ft x 15 ft x 12½ ft
= 5,625 ft³
How many washing machines can be packed into the delivery truck?
Number of washing machine in the truck = Volume of the delivery truck / Volume of the washing machine
= 5,625 ft³ / 150 ft³
= 37 1/2
Or
= 37.5
Terrel lives 2 5/6 blocks away from his best friends house. His school is 4 1/3 blocks away in the same direction. If he stops at his best friends house first how much farther do they have to walk to school.
Answer:
5/8 of a mile
Step-by-step explanation:
Let the distance from Post Office to Friend's house =D
7/8 + 5/6 + D =miles - Total distance from Georgia's house to a Friend's house.
42 minutes / 18 minutes per mile =2 1/3 miles - total distance from her house to a friend's house. So, we have:
7/8 + 5/6 + D = 2 1/3, solve for D
[21 + 20] / 24 + D = 2 1/3
41/24 + D = 2 1/3 subtract 41/24 from both sides
D =2 1/3 - 41/24
D =7/3 - 41/24
D =[56 -41] / 24
D = 15 / 24
D = 5/8 of a mile - the distance between the School and her Friend's house.

Which equation has a axis of symmetry of x=4 ?
I think you forgot to add the picture. However, any x = 4 equation will result in a graph with a vertical line on the x-axis. For example x = 20 will be a vertical line on x-axis 20.
Or, in a more difficult equation like this...
10x - 60 = 10
10x = 10 +60
10x = 70
x = 7,
where the graph looks like a vertical line with a point on the x axis on 7.

Mila owns a small business selling used books. She knows that in the last week 83 customers paid cash, 16 customers used a debit card, and 41 customers used a credit card. Based on these results, express the probability that the next customer will pay with something other than a credit card as a decimal to the nearest hundredth
Answer:
the answer is 0.71
Step-by-step explanation:
it told me
The probability the next customer will pay with something other than a credit card is 0.71.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
Number of customers paid cash = 83
Number of customers used a debit card = 16
Number of customers used a credit card = 41
Total number of customers = 140
The probability that the next customer will pay with something other than a credit card is
P(e) = (Number of customers paid cash + Number of customers used a debit card) / Total number of customers.
⇒ [tex]P(e)=\frac{83+16}{140}[/tex]
⇒ [tex]P(e)=\frac{99}{140}[/tex]
⇒ [tex]P(e)=0.7071[/tex] ≈ [tex]0.71[/tex]
Hence we can conclude that the probability the next customer will pay with something other than a credit card is 0.71.

Answer:
6168.02
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r/m)^mn
FV = Future value
P = Present value - 5000
R = interest rate = 0.03
N = number of years = 7
m = Number of compounding = 52

The question is a model of rectangular stove top with four circular burners is shown the side length of the top stove and the diameter of the burners are labeled.which measurement is the best estimate of the area and square inches of the stove top that does not include the area of the burners?
Answer: see work
Step-by-step explanation:
Total area is 24x22=528
one circle area is (pi)3^2=9(pi)
that times 4 because of 4 circles =36(pi)
so the total are minus the circles now
in terms of pi the answer is 528-36(pi)

- ZA and B are complementary angles. If mA = (x + 28)° and m ZB = (4x - 8), then find the measure of ZA.
Answer:
42 degrees
Step-by-step explanation:
"Complementary" means the angle measures add up to 90 degrees.
[tex]m\angle A+m\angle B =90^\circ\\(x+28)+(4x-8)=90\\5x+20=90\\5x=70\\x=14[/tex]

a store offers a discount of 40 off any one regular-priced item. employees also get 10% off any purchases. in which order should the discounts apply so that the employee pays the least amount?
A. Employee discount then store discount
B. They are both the same
C. Store discount then employee discount
Let's say the price of an item is $1
Scenario #1 - 40% off $1 = 40 cents OFF
The discounted price = 60 cents
Now the 10% off of 60 cents
60-6 = 54 cents.
Scenario #2 - 10% of $1
The discounted price = 10 cents
100(cents) - 10 = 90 cents
Now the 40% off of 90 cents
90-36 = 54 cents
Let's try another value to confirm
Let's say the price of an item is $2
Scenario #1 - 40% off $2 = 80 cents OFF
200-80= 120 = $1.20
Now the 10% off of $1.20
120-12= 108 = $1.08
Scenario #2 - 10% off $2 = 20 cents OFF
200-20 = 180= 1.80
Now the 40% off of $1.80
180-72 = 108 = 1.08
With these two examples we can confirm either order
will give you the same savings.
