Find the annual percent increase or decrease that y = 0.35(2.3)x models. (1 point) A.230% increase B.130% increase C.30% decreas

ipn [44]

Answer: B. 130% increase

Step-by-step explanation:

Given function : $y=0.35(2.3)^x$

If x represents the number of years, we have to determine the two values of y in consecutive terms to determine if the value of y increases or decreases after a year.

This function is equivalent to the exponential growth function

$y=A(1+r)^x$ , where A=0.35 and (1+r)=2.3, [A= initial amount , r=annual percent increase]

Thus,

$\Rightarrow\ r=2.3-1\\\Rightarrow\ r=1.3\\\Rightarrow\ r=1.3\times100\%=130\%$

Hence, the annual percent increase is 130%.

X² − 12x + 36 = 0<br><br> Solutions?

Alika [10]

Factors of 36 that add up to -12

-6 and -6

<span>(x − 6)(x − 6)
</span>
Set them both to equal 0 and solve for x

x - 6 = 0

x - 6 = 0

x = 6

x = 6

Kiran and Mai are trying to figure out if this equation is an identity, what do you think

ValentinkaMS [17]

Expanding the left side of the equation, it is found that since <u>both sides are equal</u>, yes, it is an identity.

An equality represents an identity if <u>both sides are equal</u>.

In this problem:

$(a - b)^4 = a^4 - 4a^3b + 6a^2b^2 - 4ab^3 + b^4$

Expanding the left side:

$(a - b)^2(a - b)^2 = a^4 - 4a^3b + 6a^2b^2 + 4ab^3 + b^4$

$(a^2 - 2ab + b^2)(a^2 - 2ab + b^2) = a^4 - 4a^3b + 6a^2b^2 - 4ab^3 + b^4$

$a^4 - 4a^3b + + 6a^2b^2 - 4ab^3 + b^4 = a^4 - 4a^3b + 6a^2b^2 - 4ab^3 + b^4$

Since <u>both sides are equal</u>, yes, it is an identity.
