Answer: The correct option is (B) $(2b+3)(2b-3).$

Step-by-step explanation: We are given to factorize the following expression :

$E=4b^2-9.$

We will be using the following factorization formula :

$a^2-b^2=(a+b)(a-b).$

The factorization is as follows :

$E\\\\=4b^2-9\\\\=(2b)^2-3^2\\\\=(2b+3)(2b-3).$

Thus, the required factored form is $(2b+3)(2b-3).$

Option (B) is CORRECT.

A leading bank is coming up with an investment that pays 8 percent interest compounded semiannually. What is the investment's ef

uranmaximum [27]

The effective rate is calculated in the following way:
$r = {(1 + \frac{i}{n} )}^{n} - 1$
where r is the effective annual rate, i the interest rate, and n the number of compounding periods per year (for example, 12 for monthly compounding).
our compounding period is 2 since the bank pays us semiannually(two times per year) and our interest rate is 8%
so lets plug in numbers:
$r = {(1 + \frac{8\%}{2}) }^{2} - 1 \\ r = {(1 + \frac{1}{25}) }^{2} - 1 \\ r = \frac{676}{625} - 1 \\ r = 0.0816 \: or \: 8.16\%$

Which expression can be used to find m pls help

natali 33 [55]

Answer:

∠ U = 22.62°

Step-by-step explanation:

We can use the trigonometric expression to find ∠U by using the ratio:

sin(θ) = opposite/ hypotenuse

=> sin ∠U = 7.5/ 19.5

=> ∠ U = $sin^{-1}$ ( 7.5/ 19.5)

∴ ∠ U = 22.619° ≈ 22.62°

you are building a rectangular wading pool you want the area of the bottom to be 90 ft squared you want the length of the pool t

Sindrei [870]

L=2W+3, A=LW, using L from the first in the second gives you:

A=(2W+3)W

A=2W^2+3W, and we are told A=90 so

2W^2+3W=90

2W^2+3W-90=0

2W^2-12W+15W-90=0

2W(W-6)+15(W-6)=0

(2W+15)(W-6)=0, since W>0 for all real possibilities,

W=6ft, and since L=2W+3

L=15ft

So the pool will be 6 ft wide by 15 ft long.
