40,000

All you do is multiply 4,000 by 10 to find out what 10 times of your number is, if 4,000 is only 1/10 of it.

The axis of symmetry for the graph of the function is f(x) = x2 + bx + 10 is x = 6. What is the value of b?

joja [24]

Answer:

$b=-12$

Step-by-step explanation:

we have

$f(x)=x^{2}+bx+10$

we know that

The equation of a vertical parabola into vertex form is equal to

$y=a(x-h)^{2} +k$

where

(h,k) is the vertex of the parabola

and the axis of symmetry is equal to $x=h$

In this problem we have the axis of symmetry $x=6$

so

the x-coordinate of the vertex is equal to $6$

therefore

For $x=6+1=7$ -----> one unit to the right of the vertex

Find the value of $f(7)$

$f(7)=7^{2}+b(7)+10$

$f(7)=59+7b$

For $x=6-1=5$ -----> one unit to the left of the vertex

Find the value of $f(5)$

$f(5)=5^{2}+b(5)+10$

$f(5)=35+5b$

Remember that

$f(5)=f(7)$ ------> the x-coordinates are at the same distance from the axis of symmetry

so

$59+7b=35+5b$ ------> solve for b

$7b-5b=35-59$

$2b=-24$

$b=-12$

Represent the arithmetic series using the recursive formula.

Greeley [361]

Answer:

The recursive formula is $f(n) = f(n-1) + (-7)$

Step-by-step explanation:

Given : 94, 87, 80, 73, …..

To find : Represent the arithmetic series using the recursive formula ?

Solution :

The arithmetic series is 94, 87, 80, 73, ….. with first term a=94 and common difference is d=-7

The recursive formula of the sequence 94, 87, 80, 73, …..

a(1)=94 is the first term

a(n)=a(n−1)+(-7) add -7 to the previous term

In the formula, n is any term number and a(n) is the $n^{th}$ term.

i.e. a(1) is the first term and a(n-1) is the term before $n^{th}$ term.

Therefore, the recursive formula is $f(n) = f(n-1) + (-7)$

Bridgette opened a store credit card to purchase a business suit for $463. She put the entire purchase on the credit card. Her A

irinina [24]

Begin by computing the <span>monthly interest rate like this:
</span> $\frac{14.99}{12}=1.25$
<span>Each month, we have to substract from $463 the monthly rate and the payment of 5%, which result in the following formula:
</span> $463(1-(0.05+0.0125))^3=463\times0,9375^3\\=381.5$
<span>
So, after three months, it ill remains $381.5 in </span><span>Bridgette account. </span>
