Answer:
Step-by-step explanation:
A quadratic equation in one variable given by the general expression:
Where:
The roots of this equation can be found using the quadratic formula, which is given by:
So:
As you can see, in this case:
Using the quadratic formula:
Therefore, the answer is:
Answer: About 0.1894 of a mile will be driven until you reach the exit 1000 feet if there are 5280 feet in a mile.
Units are used to describe the quantity of an object.
Given the conversion rate:
5280 feet = 1 mile
Next is to convert 1000feet to miles, we can write:
1000feet = x
Divide both expressions to get the value of x
This shows that about 0.1894 of a mile will be driven until you reach the exit 1000 feet

Answer:
The circumference of the round pizza is 21.26in
Step-by-step explanation:
To solve this exercise we first have to calculate the radius of the circle, for this we will use the formula of area of a circle and we will clear the radius
a = area = 36in²
r = radius
π = 3.14
a = π * r²
we clear r
r = √(a/π)
now we replace the known values
r = √(36in²/3.14)
r = √(11.46in²)
r = 3.385 in
now we use the formula to calculate the circumference of a circle
c = π * 2r
c = 3.14 * 2 * 3.385 in
c = 21.26in
The circumference of the circle is 21.26in
Answer:
B
Step-by-step explanation:
The function -x^4 + 1 is a polynomial graph. As such it has specific characteristics or behavior you can expect to see:
- It's leading coefficient is -1. This means the graph changes direction. Both ends of this graph face down into negative infinity.
- Its degree is 4 meaning it is an even graph. This means both ends end the same way and NOT opposite directions.
In conclusion, this graphs has ends which end the same direction and both face down.
