Answer:
D
Step-by-step explanation:
Roots are the solution to a polynomial equation. So construct the factors of the polynomial. (x-3)(x+6)(x-0). Now multiply the factors and you will get option D.
A race car driver is doing a time trial of a new car on a straight track. The car's distance from the timekeeper is represented by y=293x+50, where x is time in seconds and y is distance in feet from the timekeeper's position. How many feet from the timekeeper is the race car at the beginning? It is ft from the timekeeper.
Answer:
The distance at which the timekeeper is the race car at the start is 50 feet.
Step-by-step explanation:
You know that the car's distance from the timekeeper is represented by
y=293*x +50
where x is time in seconds and y is distance in feet from the timekeeper's position.
You want to determine how far the timekeeper is from the race car at the start. That is, the distance the timekeeper is from the car when the time is equal to zero. This indicates that x = 0. Replacing x by that value in the expression of the distance of the car from the timekeeper as a function of time and solving:
y=293*0 +50
you get:
y=50
The distance at which the timekeeper is the race car at the start is 50 feet.
The distance from the timekeeper to the race car at the beginning is 50 feet.
Let the time be x.Let the distance be y.Given the following data:
[tex]y=293x+50[/tex]Time = 0 seconds (at the beginning).To calculate how many feet (distance) from the timekeeper is the race car at the beginning:
You should note that, the time of the race at the beginning would be equal to zero (0) seconds.
Hence, the start time is equal to zero (0) seconds.
Substituting the value of x into the eqn, we have:
[tex]y=293(0)+50\\\\y=50[/tex]
Distance = 50 feet.

what is the answer to C
Answer:
C = 15
Step-by-step explanation:
Both (7c-7)° & (6c-8)° if get combined will form a straight angle i.e. 180° because both the angles lie on the same line. So,
[tex]7c - 7 + 6c - 8 = 180°[/tex]
[tex] = > 13c - 15 = 180°[/tex]
[tex] = > 13c = 180 + 15 = 195[/tex]

ALGEBRAIC model that represents the following situation: "A local fair charges an entrance fee of $5, and costs $1.25 per ride.
Answer:
y = 1.25x + 5
Step-by-step explanation:
The entrance fee is fixed, meaning it does not change. It is $5 for any person that wants to enter.
y = mx + b
only rates that change is dependent on how many rides you go on.
so 1.25 is your slope, m
y = the amount you will spend
x = the amount of rides you go on
b = the cost to enter the fair -- this is fixed.
put the equation together
PLS HALP ME!!!!!! You have $6.50 to make copies. Each copy costs $0.45. Write and solve an inequality that represents the number of copies you can make.
Step-by-step explanation:
Variable x = number of copies
6.50 <= 0.45x
Divide both sides by 0.45
6.50 ÷ 0.45 <= 0.45x ÷ 0.45
14.4444.... <= x
No more than 14 copies
6.50 <= 0.45x
6.50 <= 0.45(14.444)

Answer:
The correct answer is:
Vertically shift the graph of f(x) up 3 units
Step-by-step explanation:
The new function that is obtained by transformation is
g(x) = f(x) + 3
The +3 is not grouped with x that means that the function is shifted vertically.
Now the +3 means that the coordinates of y will be changes for each input which will shift the function upward.
Hence,
The correct answer is:
Vertically shift the graph of f(x) up 3 units

Lucy has to run two errands. She starts from home and travels 3 miles south to the post office. From the post office, she travels 4 miles east to the gas station. Then, from the gas station, she travels 5 miles to return home. The entire trip forms a triangle. What was the smallest angle made in her trip?
Answer:
Smallest angle = [tex]36.87^\circ[/tex]
Step-by-step explanation:
Given that:
Let the home be at the point A.
Lucy travels 3 miles south to reach point B.
Then 4 miles to east to reach point C and then
returns to home traveling 5 miles making it a triangle for the whole journey.
This travel is nothing but forms a right angled [tex]\triangle ABC[/tex], right angled at point B.
To find:
Smallest angle in the travel.
Solution:
In a triangle, the smallest angle is the angle opposite to the smallest side.
Therefore, the [tex]\angle C[/tex] will be the smallest.
We can use tangent trigonometric ratio here:
[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]
[tex]tan C = \dfrac{AB}{BC}\\\Rightarrow tan C = \dfrac{3}{4}\\\Rightarrow \angle C=tan^{-1}{0.75}\\\Rightarrow \angle C=36.87^\circ[/tex]
Therefore, the answer is:
Smallest angle = [tex]36.87^\circ[/tex]
