Write the linear inequality shown in the.The gray represents the shaded region.

kap26 [50]

In order to get who was right we need to solve the expression:
2a^2b(-2ab^3)^-2
The above can be written as fraction to get:
(2a^2b)/(-2ab^3)^2
=(2a^2b)/(4a^2b^6)
=1/2(a^(2-2)b^(1-6))
=1/2a^0b^-5
=1/2b^(-5)
This implies that neither of the was right

The tuition costs, c, for a local community college are modeled by c(h) = 250 200h, where h represents the number of credit hour

user100 [1]

The number of credit hours a student have to take for the two tuition costs to be equal is 2.5 hours. Option A

<h3>Equation</h3>

local community college;

c(h) = 250 + 200h

local state University;

s(h) = 300 + 180h

Where,

number of credit hours taken = h

To have equal tuition in both schools,

equate both function

250 + 200h = 300 + 180h

200h - 180h = 300 - 250

20h = 50

h = 50/20

h = 2.5 hours.

The number of credit hours a student have to take for the two tuition costs to be equal is 2.5 hours.

If a = 2^3 x 3^7 x 5^3 x 11^4 and b = 2^2 x 3^9 x 7^2 x 11 x 13, find the following: A. GCF (a, b) B. LCM (a, b)

timofeeve [1]

Answer:

A. GCF(a,b) = $2^2 \times 3^7 \times 11$

B. LCM(a,b) = $2^3 \times 3^9 \times 5^3 \times 7^2 \times 11^4 \times 13$

Step-by-step explanation:

The GCF of two or more integers is their greatest common factor. In order to find it, you must factorise them first and then do the product of the factors that appear in all the factorisations, with their least exponent.

Hence, the GCF of $a$ and $b$ is $2^2 \times 3^7 \times 11$ .

The LCM of two or more integers is their least common multiple. In order to find it, you must factorise them first and then do the product of the multiples that appear in one or all the factorisations, with their greatest exponent.

Hence, the LCM of $a$ and $b$ is $2^3 \times 3^9 \times 5^3 \times 7^2 \times 11^4 \times 13$

Calculate the rent of a decreasing annuity at 8% interest compounded quarterly with payments made every quarter-year for 7 years

Papessa [141]

The general Formula for a decreasing Annuity is:
$P = ( \frac{(1+i)^n -1}{i (1+i)^n}) R$
For this example we have:
P = 78,000
n = 7*4 = 28
i = 8%/4 = 2% = 0.02

After substituting you can find value for R, rent.
