**Step-by-step explanation:**

The given GP is : -0.5+1.5-4.5........

It is required to find the sum of 45 terms of GP.

From this GP, first term is (-0.5).

Common ratio is,

The formula use to find the sum of n terms of a GP is given by :

Substituting all values in above formula :

Hence, this is the required solution.

**Answer:**

C

**Step-by-step explanation:**

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given (h, k ) = (5, - 3 ), then

y = a(x - 5)² - 3 and with a = - 3, then

y = - 3(x - 5)² - 3 ← is a possible equation

The answer 1 because because 1-cosx^2 =sinx^2 and cotx^2+1=cscx^2 =1/sinx^2 and sinx^2/sinx^2=**1**

Hope, help and Heal.

**Answer:**

$18,200

**Step-by-step explanation:**

We want ...

f(x) = g(x)

53 +.105x = 235 +.095x . . . . use given expressions

.01x = 182 . . . . . . . subtract 53+.095x

x = 182/.01 = 18200 . . . . . divide by the coefficient of x

**Each must sell $18,200 for their weekly pay to be the same**.
