Answer: 7/8 > 2/8

Step-by-step explanation:

7/8 is greater than 2/8 because 7 is greater than 2. Also they have the same denominator.

State whether the decay is linear or exponential, and answer the associated question. The value of a car is decreasing by 9% p

Sunny_sXe [5.5K]

Answer:

Exponential
A(2)=$9109.10

Step-by-step explanation:

Since the value of the car decreases by a common factor each year, the decay is exponential.

An exponential decay function is of the form

$A(t)=A_0(1-r)^t$ where:\\Initial Value, A_0=\$11,000\\$Decay Factor, r=9%=0.09$

Therefore, the function modeling the car's decay is:

$A(t)=11000(1-0.09)^t$

We want to determine the car's value in two years.

When t=2

$A(2)=11000(1-0.09)^2\\A(2)=\$9109.10$

The value of the car in 2 years will be A(t)=$9109.10

Kyle determines that y ≥ − 8/3 x-4 is shown on the graph. Is Kyle correct? If not, determine the correct inequality.

Troyanec [42]

Answer:

C) No, Kyle is incorrect. The correct inequality is $\displaystyle y > -\frac{8}{3}x - 4$

Step-by-step explanation:

This graph has a dashed line, so it would be either less than or greater than. The only way to find out is to use the zero-interval test [test point (0, 0)] to ensure whether we share the opposite portion [the portion that does not contain the origin] or the portion that DOES contain the origin. This is where we verify the inequality as false or true:

Greater than

$\displaystyle 0 > -\frac{8}{3} - 4 → 0 > -4$ ☑

Less than

$\displaystyle 0 < -\frac{8}{3} - 4 → 0 ≮ -4$

This graph is shaded in the portion of the origin, so we choose the greater than inequality statement.

I am joyous to assist you anytime.

Please I need Help!!!!!!!!!!!!!! with number 1 in scientific notation 5 x 10 to the forth power divided by 25 x 10 to the second

cluponka [151]

Answer:

200,000

Step-by-step explanation:

WE MUST USE THE PEMDAS RULE / ORDER OF OPERATION:

Parenthases

Exponent

Multiply

Divide

Add

Subtract

((5 x (10 to the 4th)) / 25) TIMES (10 to the second)

FIRST WE WORK ON THE FIRST PARENTHESIS:

10 to the 4th (10 x 10 x 10 x 10) = 10, 000

MULTIPLE 10, 000 by 5 (10,000 x 5 = 50, 000)

Then DIVIDE by 25 (50, 000 ÷ 25 is 2,000)

WE HAVE 2000 for parenthesis 1.

Now the second one:

10 to the 2nd in 10 x 10....thats equal to 100

2000 x 100 is 200,000! I HOPE YOU UNDERSTAND
