Answer:

A. b2 – 4ac = 0

Step-by-step explanation:

Hey user☺☺

Option a is correct

Because the graph has only one solution.

As the graph touches the x-axis at one point that means that it will have only one solution for x. But we know that a quadratic equation has two solutions. So the graph will have two equal solution and therefore the discriminant will be 0.

Hope this will help☺☺

blondinia [14]

it is not because prime factorization is a number broken down by its prime factors

4 x 3 x 20 x 8 x 22 = 42240

the correct prime factorization of 42240 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5 x 11

A bank features a savings account that has an annual percentage rate of 3.5% with interest compounded quarterly. Vanessa deposit

vazorg [7]

Answer:

APY = 0.04 or 4%

Step-by-step explanation:

Given the annual percentage rate of 3.5% that is compounded quarterly, and a principal of $6,500:

We can use the following formula to solve for the annual percentage yield (APY):

$APY = (1 + \frac{r}{n})^n - 1$

where <em>r</em> = interest rate = 3.5% or 0.035

<em> n</em> = number of compounding periods per year = 4

We can plug in the values into the equation:

$APY = (1 + \frac{r}{n})^n - 1$

$APY = (1 + \frac{.035}{4})^4 - 1$

$APY = (1 + 0.00875)^4 - 1$

$APY = (1.00875)^4 - 1$

APY = 1.03546 - 1

APY = 0.04 or 4%

For each of the functions below, indicate whether the function is onto, one-to-one, neither orboth. If the function is not onto

Karo-lina-s [1.5K]

Answer:

$f_{1} :Z \rightarrow Z$ is one to one mapping, it is not onto mapping

Step-by-step explanation:

$f_{1} :Z \rightarrow Z\\ f_{1} (x) = x^{3}$

f₁(x) is one to one mapping

Let $x, y \epsilon Z$

f₁(x) = f₁(y):

x₁³ = y₁³

f₁(x) is not onto mapping

Example: If f₁(x) = 7,

x₁³ = 7

$x_{1} = \sqrt[3]{7}$

x₁ is not an element of Z

$f_{1} :Z \rightarrow Z$ is one to one mapping, it is not onto mapping
