$(x + y)^2 = 36$

$x^2 + 2xy + y^2 = 36$

$x^2+ y^2 = 36 - 2xy = 36- 2(-7)= 36+14=50$

Answer: 50

Rewrite the following expression using the properties of logarithms. log2z+2log2x+4log9y+12log9x−2log2y

kramer

Use the rules of logarithm:
1. log(x)+log(y)=log(xy)
log(x)-log(y)=log(x/y)
2. k*log(x) = log(x^k)
log(x)/k = log(x^(1/k))

<span>log(2z)+2log(2x)+4log(9y)+12log(9x)−2log(2y)
=</span>log(2z)+log(4x^2)+log(9^4y^4)+log(9^12x^12)−log(4y^2)
=log(2z)+log(4x^2)+log(6561y^4)+log(282429536481x^12)−log(4y^2)
=log(59296646043258912 * x^14 * y^6 * z)

John and 4 friends are going out for pizza for lunch. They split one pizza and 5 large drinks. The pizza cost $12.00. After usin

m_a_m_a [10]

well if the pizza costs $12.00 then that leaves $2.25

$14.25-$12.00=$2.25

and then take $2.25 and devide it by 5 for the amout each soda costs

$2.25/5=$0.45

each soda costs $0.45

Find the sum of the geometric series 9000-900 +...+ 0.009

bagirrra123 [75]

Based on the calculations, the sum of this geometric series is equal to 9,990.

<h3>The standard form of a geometric series.</h3>

Mathematically, the standard form of a geometric series can be represented by the following expression:

$\sum^{n-1}_{k=0}a_1(r)^k$

Where:

a₁ is the first term of a geometric series.

r is the common ratio.

<h3>How to calculate the sum of a geometric series?</h3>

Also, the sum of a geometric series is given by this mathematical expression:

$S=\frac{a_1(1-r^n)}{1-r}$

<u>Given the following data:</u>

First term, a = 9000.

Common ratio, r = 900/9000 = 0.1

Substituting the given parameters into the formula, we have;

$S=\frac{9000(1-0.1^3)}{1-0.1}\\\\S=\frac{9000(1-0.001)}{1-0.1}$

S = 9000(0.999)/0.9

S = 8,991/0.9

S = 9,990.

TUILS<br> If f (x) = 8x and g(x) = 2x +1, find (fog)(x).

S_A_V [24]

Answer:

Step-by-step explanation:

(fog)(x) = f(x)*g(x)

= 8x * (2x + 1)

= 8x * 2x + 8x * 1

= 16x² + 8x
