Evaluate the following expression (-3)^-2
OleMash [197]
<h3>Answer: the fraction 1/9</h3>

It is approximately equal to 0.1111

=================================

To get this answer, we use the rule

x^{-k} = \frac{1}{x^k}

The negative exponent tells us to apply the reciprocal to get the exponent to be positive.

So,

(-3)^{-2} = \frac{1}{(-3)^2}\\\\(-3)^{-2} = \frac{1}{9}

Squaring -3 means you square the negative as well

(-3)^2 = (-3)*(-3) = 9

Two friends, Ryan and Tressa, are on vacation. They decide to go bungee jumping off a platform. Their height from the ground can
eimsori [14]

80 units

Step-by-step explanation:

Step 1 :

Given,

The function representing the height is y = 4x^2-32x+80

where the x represents the time after they jumped and y represents their height above ground.

We need to find the platform's height.

Step 2 :

Since x represents the time after they jumped, x = 0 when they have not started jumping and the corresponding y will give the height before they start jumping which would be the height of the platform

Step 3:

When x = 0 we have

y = 0-0+80 = 80

So the height of the given platform is 80 units.
