Answer:

Step-by-step explanation:
which of the following is true about f(x) and g(x)
The option (D) "f(x) and g(x) are closed under the addition because when added, the result will be a polynomial is correct.
What is polynomial?Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
We have given two polynomials:
[tex]\rm f(x) = \rm a_0+a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
[tex]\rm g(x) = \rm b_0+b_1x+b_2x^2+b_3x^3+b_4x^4..........b_mx^m[/tex]
If we add the above two polynomials:
= f(x) + g(x)
[tex]= (\rm a_0+a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n) + (\rm \rm b_0+b_1x+b_2x^2+b_3x^3+b_4x^4..........b_mx^m)[/tex]
The above expression is also a polynomial.
Thus, the option (D) "f(x) and g(x) are closed under the addition because when added, the result will be a polynomial is correct.

49 is 160% of what number?
Answer:
x = 30.63
Step-by-step explanation:
Answer:
30.63
Step-by-step explanation:
We have, 160% × x = 49
or, 160/100 × x = 49
Multiplying both sides by 100 and dividing both sides by 160,
we have x = 49 ×
100/160 x = 30.63
If you are using a calculator, simply enter 49×100÷160, which will give you the answer.

Answer: 64 [tex]cm^{2}[/tex]
Step-by-step explanation:
First, you need to find the area of the parallelogram (bh)
10 * 7 = 70
since you only need the shaded region, find the area of the non shaded box and subtract that from the area.
3 * 2 = 6
70 (whole area) - 6 (nonshaded area) = 64

Faye’s bank charges her a $2.25 service fee every time she uses an out-of-network ATM. If Faye uses an out-of-network ATM twice a week, how much money does she pay in service fees every year?
a.
$240.25
b.
$225.00
c.
$200.75
d.
$234.00
Answer:
$234
Step-by-step explanation:
There are 52 weeks in a year.
1 year = 52 weeks
Faye’s bank charges her a $2.25 service fee every time she uses an out-of-network ATM.
Faye uses an out-of-network ATM twice a week.
Amount in a week = 2×2.25 = $4.5
For 52 weeks,
Amount = 52 × 4.5
= $234
So, she must pay $234 every year. Hence, the correct option is (d).
Answer:
d

Exponential and linear refer to the type of a function by looking at the power of the independent variable.A linear function is one where the independent variable is to the power of 1. For example, in the linear equation y = mx+b, x is the aforementioned independent variable. The term linear comes from the plot of the function; regardless of the values of m and b, the graphed function will always be a line.An exponential function is one where the independent variable is to a non-trivial (not 0th or 1st) power. These are typically of the form y=a⋅bx. The term exponential comes from the use of exponentiation in the independent variable.An exponential graph is curved upwards, while a linear graph is a straight line. One of the most important distinctions between linear and exponential functions is how (and how quickly) they increase or decrease. Linear functions increase proportionally; an increase in x has a corresponding additive increase in y. Exponential functions, however, increase exponentially; that is, an increase in x has a corresponding multiplicative increase in y.[tex]\huge\underline{\sf{\red{Note:}}}[/tex]

Sam needs to solve 4(5 – a) = 12. Describe a move Sam could use to start to solve the equation.
Answer:
Distribute
Step-by-step explanation:
4 x 5 = 20
4 x -a = -4a
-4a + 20 = 12
-20 From both sides
-4a = -8
Divide both sides by negative 4
a = 2
Answer:
Step-by-step explanation:
4(5-a)=12 divide each side by 4
5-a=3 subtract 5 from each side
-a=-2 divide each side by -1
a=2
or
4(5-a)=12 carry out multiplication indicated on left side
20-4a=12 subtract 20 from each side
-4a=-8 divide each side by -4
a=2

A medium cheese pizza costs $11. Each topping added on the pizza costs $1.50. A pizza with t
toppings costs $23. How many toppings are on the pizza?
Answer:
8 toppings
Step-by-step explanation:
We need to subtract the price of the pizza itself from the toppings. To do this we need to subtract 11 from 23.
23-11=12
Now we divide 12 by 1.50 because every topping equals 1.50.
12÷1.50=8
Our answer is 8 toppings.

A dog and a cat start running from the same corner around the rectangular garden. Dog runs west and the cat runs north. Cat's speed is 1 meter per second faster than the dog's speed. After 2 seconds the distance between them is 10 meters. Find their speed in meters per second.
Answer:
Dog: 3 meters per second
Cat: 4 meters per second
Step-by-step explanation:
It is given that they are running from a corner around a rectangular garden, the dog runs west and the cat runs north, after 2 seconds the distance between them is 10 meters.
This forms a right triangle, the hypotenuse being 10.
So using the Pythagorean theorem we know that:
a^2 (dog's distance traveled after 2 seconds) + b^2 (cat's distance traveled after 2 seconds) = c^2 (10^2=100)
So now we can use trial and error, therefore figuring out the measurements of the two sides of the right triangle are 6 and 8. We know that this is the distance traveled after 2 seconds so we divide both integers by 2 and get 3 and 4.
So, the dog travels 3 meters per second and the cat travels 4 meters per second.
Their speed in m/s is 3 m/s for dog and 4 m/s for cat.
What is Speed?This is defined as the magnitude of the rate of change of its position with time.
We were told that they ran ran from a corner around a rectangular garden, the dog runs west and the cat runs north and after 2 seconds the distance between them is 10 meters.
This depicts a right triangle where the hypotenuse being 10.
Pythagorean theorem = a² + b² = c²
= a² + b² = 100
We can deduce that the measurements of the two sides of the right triangle are 6 and 8. Since it is the distance traveled after 2 seconds, we divide both integers by 2 and get 3 and 4.
Therefore, the dog travels 3 m/s and the cat travels 4m/s.

Find the measure of an exterior angle of a regular polygon with 19 sides. Round to the nearest tenth if necessary.
Question 10 options:
Yes; Opposite sides are parallel.
Yes; Diagonals bisect each other.
Yes; Diagonals are congruent.
No; Diagonals are not congruent.
Answer:
Each exterior angle measures 360/19 degrees, approximately 18.9 degrees.
Step-by-step explanation:
Start at one vertex of the polygon and go clockwise. When you reach the next vertex, you change direction. At each vertex you change direction by the same angle. When you are back to the first vertex, and start along the first side, you have completed a full 360 degrees clockwise. Since there are 19 sides and vertices, you must have turned 360/19 degrees at each vertex.

Does the scatterplot below relate to a statistical question? Explain
Answer: Yes we have a statistical question
This is because we have a sample of data, and it's useful and meaningful to compute sample statistics on that data. For example, we can form a regression line to help see the pattern that the older you get, the more you tend to study. There isn't a direct connection and there are confounding variables, but there's a positive correlation of some sort.
Once we figure out the sample statistics, we can use it to estimate the population at large. The population could be students at a certain school or certain area of the country; while these dots represent the small sample from that population. Keep in mind that anyone in the sample must be part of the population, but not vice versa. We say that the sample is a subset of the population.
