98-10.85 = 87.15

skateboard cost 64

87.15 -64 = 23.15 is what she can spend on cookies

An investment made in the stock market decreased at a rate of 2.2% per year for 10 years. What is the current value of
never [62]

Answer:

$800,500 (nearest dollar)

Step-by-step explanation:

The given scenario can be modeled as an <u>exponential equation</u>.

<u>General form of an exponential function</u>:

 f(x)=ab^x

where:

  • a is the initial value (y-intercept)
  • b is the base (growth/decay factor) in decimal form
  • x is the independent variable
  • y is the dependent variable

If b > 1 then it is an increasing function

If 0 < b < 1 then it is a decreasing function

The initial value (a) is the value of the investment.

Therefore, a = 1,000,000.

If the investment <u>decreases</u> by 2.2% each year, then it will be 97.8% of the previous year.

Therefore, b = 97.8% = 0.978.

Substitute these values into the formula to create a general equation for the scenario:

f(x)=1000000(0.978)^x

(where x is the time, in years).

To find the value of the investment after 10 years, substitute x = 10 into the formula:

\implies f(10)=1000000(0.978)^{10}=800500.1586

Therefore, the value of the investment after 10 years is $800,500 (nearest dollar).

HELP PLEASE <br> Write the inequality that models the number granola bars (12) you need to buy.
Goshia [24]
The correct question in the attached figure

Let
x-------------> <span>the number of granola bars 
y-------------> the pounds of fruit

we know that

if 12 bars------------> cost $12
 1 bars--------------> X
X=12/12---> x=$1
1 bar---------> cost $1

if 9 pounds of fruit----------> cost $36
 1 pound-------------------> X
X=36/9--------> x=$4
1 pound -------> cost $4

</span><span>expression for the total cost=(1)*x+(4)*y----------> x+4y
</span><span>x=12
y=9
then
</span>the total cost=12+4*9----- $48

<span>an inequality that compares
the total cost with the amount you have to spend is
x+4y<=48
</span>
using a graph tool see the attached figure

<span>the inequality that models the number of granola bars you need to buy is
</span>
x<=12  the solution for the number of granola bars is the interval [0,12]

Which statement describes the translation of y = −1 over 5(x + 5)2 + 2 from standard position?
lesantik [10]

Answer:

Option B

Step-by-step explanation:

Given equation is

y=\frac{-1}{5(x+5)^{2} } +2

The original graph would be

y=-\frac{1}{x^{2} }

From this transformations done are

a) horizontal shift of 5 units to the left

b) shrink vertical by scale factor 1/5

c) vertical shift of 2 units up

Hence option A is not right

Option B is right.

Similarly C and D are not right.
