Answers

Answer 1

Answer:

C

Step-by-step explanation:

Because 0 repeats

Answer 2

The answer is C, because the 0 repeats itself in C and in a function, X does NOT repeat. And in this case, X is 0, which repeats.

Convert the equation from vertex form to standard form.

Answers

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].

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.

Answers

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 gallons

Leakage per minute = 2 gallons

Number of minutes = x

Total water remaining in the pool = y

The equation

Total 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

Answers

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

Someone please help!!! It’s timed!

Answers

Answer:

a) x = 10

b) DA = 24

c) perimeter = 110

Step-by-step explanation:

a) Since it's a parallelogram, the opposite sides are of equal length. This means that line DC = AB, so u can substitute in the values and solve for x:

DC = AB

5x - 18 = 2x + 12           (move terms so that like terms are on the same side)

5x - 2x = 12 + 18           (simplify like terms)

3x = 30                         (divide by 3 on both sides to isolate the x)

x = 10

b) now that u know the value of x, you can use it to find the length of DA. again, opposite sides are equal, so DA = BC, which means DA = 3x - 6. substitute in your known value of x and solve:

3x - 6

= 3(10) - 6

= 30 - 6

= 24

Therefore, the length of DA - 24

c) Since u know the length of DA (and therefore BC), u just have to find the length of either DC or AB and then multiply that by 2 and add it.

First, substitute in the value of x for either DC or AB (i'm gonna use AB)

2x + 12

= 2(10) + 12

= 20+12

= 32

now, to find the perimeter use this formula: 2(AB) + 2(DA)

this equals to 2(32) + 2(24) = 64+46 = 110

and that's the perimeter!

hope this helps!

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?

Answers

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!
