Answer:
21.15 ft
Step-by-step explanation:
18.7 - 14.3 = 4.4 = pool depth
25.55-4.4 = 21.15 = slide height
Answer:
C
Step-by-step explanation:
using the pythagorean theorem,
a²+b²=c²
8²+7²=c²
64+49=c²
113=c²

10.63=c
Answer:
3 : 5
Step-by-step explanation:
Given the question "<span>Which algebraic expression is a polynomial with a degree of 2?" and the options:
1).

2).

3).

4).

A polynomial </span><span>is
an expression consisting of variables and
coefficients, that involves only the operations of addition,
subtraction, multiplication, and non-negative integer exponents of
variables.
</span><span>The degree of a polynomial is the highest exponent of the terms of the polynomial.
For option 1: </span><span>It contains no fractional or negative exponent, hence it is a polynomial. But the highest exponent of the terms is 3, hence it is not of degree 2.
For opton 2: It contains a fractional exponent which violates the definition of a polynomial, hence, it is not a polynomial.
i.e.

For option 3: </span><span>It contains a negative exponent which violates the definition of a polynomial, hence, it is not a polynomial.
i.e.

For option 4: It contains no fractional or negative exponent, hence it is a polynomial. Also, the highest exponent of the terms is 2, hence it is of degree 2.
</span>
Therefore, <span>

s a polynomial with a degree of 2. [option 4]</span>
Answer:
(1, -1)
Step-by-step explanation:
You have the point ...
(3, f(3)) = (3, -1)
The corresponding point on the horizontally compressed graph will be ...
(3x, f(3x)) = (3, -1)
(x, f(3x)) = (1, -1) . . . . . the first coordinate of the given point is divided by 3
