Answer: The answer to this question is (2a-5)(2a+5)
Step-by-step explanation:
- Because first, you have to write the quadratic equation 4a^2-25 in exponential form
- Then, you calculate the product by multiplying the terms with equal exponents by multiplying their bases
(2a)^2-5^2
- And then last but not least, using a^2-b^2=(a-b)(a+b), factor the expression
(2a-5)(2a+5) and then there's your answer and your explanation!!!!!
D the slope for function A one is -2 and the slope for function B is 4
Answer:
no solution
Step-by-step explanation:
hello
this is always false so there is no solution
Answer:
In order to answer this you would need to use this equation: <em>A = πr² </em> (See explanation)
Step-by-step explanation:
So, The circumference of the circle is 65n?
What you need to do is <em>A = πr² </em>
Let's divide 65n by Pi (65/3.14)
That equals 20.70n
Now we have the diameter of the circle. We need the radius for <em>A = πr² .</em>
We need to divide the diameter by two (20.70/2)
We now have the radius of the circle: 10.35n
Now we need to plug 10.35n in our Area equation :<em>A = π10.35² </em>
So now we multiply the Radius by Pi (π * 10.35)
This means that the area of our circle is: A = 32.49
Your answer Is 32.49n
Answer:
≈9
Step-by-step explanation:
V= πr^2(h/3)
1356.48= πr^2(16/3)
r= 8.99 or about 9
