Answer:
Step-by-step explanation:
its 22.00 or just 22
Surface area o fthe ball = 4 * 3.14 * radius^2
if diameter = 1.680 then radius = 1/2 * 1.680 = 0.84
so surface area = 4 * 3.14 * 0.84^2 = 8.862
Answer:
1. x^2 +2x -24 = 0
2. x^2 -7x +10 = 0
Step-by-step explanation:
If you look at the factored and expanded forms of a quadratic with solutions p and q, you see ...
(x -p)(x -q) = x^2 -(p+q) +pq
The x-term coefficient is the opposite of the sum of solutions.
The constant is the product of solutions.
This knowledge lets you write down the standard form equation with no particular effort.
1. x^2 +2x -24 = 0
2. x^2 -7x +10 = 0
<h3>A number that multiplies a variable in a term is known as a coefficient.</h3>
Given the term: 6x^3, we can identify three parts:
The coefficient, 6, is the constant that is being multiplied by the variable.
The variable, x, is a number with an unknown value, or with multiple potential values.
The exponent, 3, is the power with which the variable is being raised to.
28 times 3 first you do 8 times 3 than 2 times 8 then add them together
