First convert 22 to decimal form. You do this by dividing the percent by 100.
22 / 100 = .22

Then multiply the dollar amount by the percentage in decimal form.

$45 * .22 = $9.9

So 22% of $45 is $9.9.

Then you subtract $9.9 from $45.

$45 - $9.9 = $35.1

$43,800 at 4.8% for 2 years

Mashutka [201]

It would be: P * R * T /100
= 43800 * 4.8 * 2 /100
= 420480 / 100
= 4204.80

So, your final answer is $4204.80

Hope this helps!

Use the indicated properties of realnumbers to complete the blanks of the following statements.

jek_recluse [69]

Answer:

13. $50+43=43+50$

14. $5+(7+6)=(5+7)+6$

15. $-15+0=0-15=-15$

16. $\frac{3}{4}*\frac{4}{3}=1$

17. $25*4=4*25$

Step-by-step explanation:

Let "a", "b", and "c" real numbers.

- Commutative Property of Addition states that:

$a+b=b+a$

- Associative Property of Addition states that:

$(a+b)+c=a+(b+c)$

- Additive Identity Property states that:

$a+0=0+a=a$

- Commutative Property of Multiplication states that:

$a*b=b*a$

- Multiplicative Inverse Property states that:

$a*\frac{1}{a}=1$ ( $a\neq 0$ )

Knowing these properties, we can solve the exercise:

13. By the Commutative Property of Addition:

$50+43=43+50$

14. By the Associative Property of Addition:

$5+(7+6)=(5+7)+6$

15. By the Additive Identity Property:

$-15+0=0-15=-15$

16. By the Multiplicative Inverse Property:

$\frac{3}{4}*\frac{4}{3}=1$

17. By the Commutative Property of Multiplication:

$25*4=4*25$

What is the vertex form of f(x)= 5x^2 +20x-16

Amanda [17]

Answer:

Vertex of given quadratic function is (-2,-36)

Step-by-step explanation:

Given function

We have to find the vertex of the given function .

The standard quadratic function is represented by ,

Where (h,k) represents the vertex and a ≠ 0.

If a is positive, the graph opens upward, and if a is negative, then it opens downward.

We first write the given equation in standard form ,by using completing square,

We know

First taking 5 common from function, we have,

Comparing we have, a = x and

-2ab= +4x ⇒ -2b = 4 ⇒ b = -2

Add and subtract b , we get,

On simplifying, we have,

We get,

On comapring with standard equtaion , we have h = -2 and k = -36

Thus, vertex of given quadratic function is (-2 ,-36)
