Convert the equation from vertex form to standard form.
Given:
The vertex form of a quadratic equation is
[tex]y=-5(x+2)^2-10[/tex]
To find:
The standard form of the given quadratic equation.
Solution:
We have,
[tex]y=-5(x+2)^2-10[/tex]
Using the formula [tex](a+b)^2=a^2+2ab+b^2[/tex], we get
[tex]y=-5(x^2+2(x)(2)+(2)^2)-10[/tex]
[tex]y=-5(x^2+4x+4)-10[/tex]
Using distributive property, we get
[tex]y=-5x^2-20x-20-10[/tex]
[tex]y=-5x^2-20x-30[/tex]
Therefore, the standard form of the given equation is [tex]y=-5x^2-20x-30[/tex].

. If the puppies are 36% of the total dog and cat population, how many dogs and cats are in the animal shelter?
Answer:
Total number of cat and dogs = 32
Step-by-step explanation:
Missing:
Total number of puppies = 18
Puppies percent = 36%
Find:
Total number of cat and dogs
Computation:
Total number of Animals = 18 (100/36)
Total number of Animals = 50
Total number of cat and dogs = Total number of Animal - Total number of puppies
Total number of cat and dogs = 50 - 18
Total number of cat and dogs = 32

In what ways are linear functions and exponential functions the same? In what ways are they different? How can they be used to model real world situations?
Answer:
In linear functions, rate of change is constant: as x goes up, y will go up a consistent amount. In exponential functions, the rate of change increases by a consistent multiplier- it will never be the same but there will be a pattern. Exponential functions are used in real world situations such as bacterial growth/decay, population growth/decline, and compound interest. Linear functions/equations can be used for comparing rates of pay. Hope this helped!

Kids filled up a swimming pool with 5000 gallons of water. The water leaked out at 2 gallons per minute. Write a linear equation to model this situation.
Answer:
Y= -2x + 5000
Step-by-step explanation:
The linear equation which model the situation is y = 5000 - 2x
Given:
Total quantity of water in the swimming pool = 5000 gallonsLeakage per minute = 2 gallonsNumber of minutes = xTotal water remaining in the pool = yThe equationTotal water remaining in the pool = Total quantity of water in the swimming pool - (Leakage per minute × Number of minutes)
y = 5000 - (2 × x)
y = 5000 - 2x
Therefore, the linear equation which model the situation is y = 5000 - 2x

Find the value of the missing Angles:
Answer:
Angle 1 is 58 and Angle 2 is 32 because all triangles equal to 180 and where the lines bisect creates a 90 degree angle in each triangle. Add 90 and 32 together, then minus 122 from 180 and you get angle 1 and the angle across from angle 1. For angle 2, add 58 and 90, then subtract that from 180. You'll end up getting 32
