-3 is a zero for the polynomial:
x^3 + 7x^2 + 16 x + 12
True or False
Answer:
true
Step-by-step explanation:
If x = - 3 is a zero of the polynomial then f(- 3) = 0
f(x) = x³ + 7x² + 16x + 12
= (- 3)³ + 7(- 3)² + 16(- 3) + 12
= - 27 + 63 - 48 + 12
= 0
Since f(- 3) = 0 then x = - 3 is a zero of the polynomial
A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 200 nails and each large box has 400 nails. The contractor bought twice as many small boxes as large boxes, which altogether had 3200 nails. Graphically solve a system of equations in order to determine the number of small boxes purchased, x,x, and the number of large boxes purchased, yy.

Answer:
bus: 324 ft long
P-H: 1154 miles
Step-by-step explanation:
In each case, we can use the relation that the length of an arc (s) is found by ...
s = rθ
where r is the radius and θ is the angle in radians.
__
1. 2°20'50" = (2 + 20/60 + 50/3600)(π/180) radians ≈ 0.0409668 radians
Then the length of the bus is ...
(0.0409668)(1.5 mi)(5280 ft/mi) = 324 ft
__
2. The difference in latitude is ...
41°17'5" -24°45'30" = 16°31'35" ≈ 0.288440 radians
Then the mileage between latitude lines is ...
s = (4000 mi)(0.288440 radians) ≈ 1154 miles
__
Additional comment
Neither of these problems should be considered to be realistic. An actual bus will subtend a far smaller angle at the given distance. The distance between cities must take into account longitude as well as latitude (and the latitudes must be properly associated with the cities).

If gas costs $4.55 per gallon how many whole gallons of gas could you buy with $12.00?
The amount of gallons of gas that can be bought with $12 is 2.64 gallons.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
Cost of gas per gallon = $4.55
This can be written as,
1 gallon = 4.55
Multiply 12/4.55 on both sides.
12/4.55 gallons = 12/4.55 x 4.55
2.64 gallons = 12
This means,
2.64 gallons for $12.
Thus,
2.64 gallons can be bought for $12.

9x - 4y= 19
4x + 4y= 20
Answer:
x=3 and y=2
Step-by-step explanation:
9x - 4y= 19
4x + 4y= 20
add both equations;
13x = 39
x= 3
using 4x + 4y= 20;
4(3) +4y=20
12+4y=20
4y= 20-12=8

Step-by-step explanation:
an = d (n - 1) + c
an = what you're looking for
n = term position
d = the common difference, in your case, 16
c = first term of the sequence, or -27

18% discount on a list price of $25
Answer:
$20.50
Step-by-step explanation:
100% price - 18% discount = 82%.
82% can be written as .82
The original price was 25, so we multiply 25 by 0.82. We get $20.50.
If you are looking for the amount saved, subtract 20.5 from 25. We get $4.50.
A goalie makes 12 saves in 4 games. What is the unit rate of saves per game?
Answer:
3 saves per day
Step-by-step explanation:
Since we are finding the number of saves per day, our first dividor will be the number of saves, then we divide by the other number. We have 12 saves in total, and four games, so we will have to divide.
12 divided by 4 is equal to 3.
The answer to the question must be 3.
Answer:
12 saves/ 4 games = 3 saves/ 1 game = 3 saves per game
Step-by-step explanation:
A ration is basically a division problem. Divide until you get a denominator of 1.
12/ 4 = 3/ 1
So, if he makes 12 saves in 4 games, then he makes 3 saves per game.
Solve for a: -8b+2a=6c
Answer:
a=3c+4b
Step-by-step explanation:
-8b + 2a = 6c
(-8b + 2a) + 8b = 6c + 8b
-8b + 2a + 8b = 6c + 8b
-8b + 8b + 2a = 6c + 8b
2a = 6c + 8b
2a/2 = 6c + 8b/2
a = (2x3)c + [tex]2^{3}[/tex] x b)/2
a = 3c + 4b
