Answer:
4x + 3
10x² - 7x + 3
18x² - x + 5
Step-by-step explanation:
A polynomial must consist of 2 terms, one with a variable ( x ) and one as a constant ( any number )
An example of a number with a variable is 4x
An example of a constant is 3
add the two together 4x + 3 and you get a polynomial
More examples are 5x + 9 or -2x - 8
Polynomials can have more than 2 terms. ( the third term has an exponent and variable )
An example of a polynomial with more than 2 terms is 10x² - 7x + 3
Answer:
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
Answer:
Step-by-step explanation:
First we need to do 350 - 15 since 350 is our total and we already started at 15m.
Next divide the remainder (335) by 5 because that’s how fast we are moving, the final answer is 67 minutes.
A pyramid or triangular prism is a polyhedron that has a base, which can be any polygon, and three or more triangular faces that meet at a point called the vertex.
<u>Explanation:</u>
- These triangular sides are sometimes called the lateral faces to distinguish them from the base.
- It is a polyhedron that has a base, which can be any polygon, and three or more triangular faces that meet at a point called the vertex.
- The base of the triangular prism is in the shape of a quadrilateral and the lateral face is in the shape of a triangle.
Distance of the person from the building (x)
tan 24 = 20/x => x = 20/tan 24 = 44.92 ft
The height of the building above the height of the person and the distance of the person from the building forms two legs of right angled triangle.
Therefore, if h is the height of the building, then;
tan 31 = (h-20)/44.92
h-20 = 44.92 tan 31
h = (44.92 tan 31) + 20 = 26.99 + 20 = 46.99 ft
