Your answer should be 86.68.
Mean: you add up all the numbers and divide it by the total of the numbers, in this case there are a total of 11. I added all of them up and got 953.5 and divided by 11. Hoped i helped

Step-by-step explanation:
4x^2-8x-5=0
The discriminant is the number under the √. In this case it's 144
With no limiting factors to the growth of the plants, the number of months have passed since the plants were first introduced is 23.1.
<h3>What is an exponential function?</h3>
Exponential function is the function in which the function growth or decay with the power of the independent variable. The curve of the exponential function depends on the value of its variable.
A type of plant is introduced into an ecosystem and quickly begins to take over.
A scientist counts the number of plants after m months and develops the equation to model the situation, which is given as,

Most recently, the scientist counted 138 plants.

Taking log both sides of the equation,

Thus, with no limiting factors to the growth of the plants, the number of months have passed since the plants were first introduced is 23.1.

Answer:
angle C = 78
angle D = 108
Step-by-step explanation:
the measure of angle A is 102
To find the measure of angle C
let Angle C be x
102 + x = 180 (linear pair)
x = 180 -102
x = 78
angle C = 78
angle B = 78 (vertically opposite angles are equal)
angle D = 108 (vertically opposite angles are equal)
