Step-by-step explanation:

1. The firefighters gear PLUS his weight is how much he weighs in total.

2. An added fee is usually represented as a registration fee or staring fee. There was 45w which should represent the fee she paid every week.

3. The dolphin swims at a rate of 25 kilometres per hour. The graph represents the distance the dolphin traveled because in two hours the dolphin would travel 50 kilometres (25 kilometres*2 hours) and so on.

Estimate then find the sum or difference 8.5+1.8

Answers

Estimating usually means rounding to the nearest whole number to make it so that you can do the math in your head.
So, 8.5 becomes 9, and 1.8 becomes 2.
The sum would then be 11
And the difference is 7

Which of these number is irrational?the square root of 36
the square root of 49
the square root of 13
the square root of 121

Answers

The answer is the square root of 13 because it is the only one that gets square rooted and does not come out even. Hope this helped.

The square root of 36 is 6, the square root of 49 is 7, the square root of 121 is 11. So the answer is the square root of 13.

You are standing in one big palace where a king and his 5 queens stay. Each queen has 5 rooms. In each room there are 5 big cats. Each big cat has 5 little cats. Each cat has 4 legs.How many legs are there in the palace? Take ur time...

Answers

You = 2

King = 2

5 Queens = 5 X 2 = 10

5 X 5 = 25
There are 25 rooms belonging to Queens.

25 X 5 = 125
There are 125 big cats.

125 X 5 = 625
There are 625 little cats.

625 + 125= 750
There are 750 cats in total.

750 cats = 750 X 4 = 3000

Total legs = 2 + 2 + 10 + 3000 = 3014
There are 3014 legs in the palace.

Which function has a minimum and is transformed to the right and down from the parent function, f(x) = x2?g(x) = –9(x2 + 2x + 1) – 7
g(x) = 4(x2 – 6x + 9) + 1
g(x) = –3(x2 – 8x + 16) – 6
g(x) = 8(x2 – 6x + 9) – 5

Answers

Answer:

g(x) = 8(x2 – 6x + 9) – 5

Step-by-step explanation:

A function with a form (x - a)^2 - b where a and b are some constants are a transformation to the right and down from the parent function, f(x) = x^2. Then, option:

g(x) = 4(x2 – 6x + 9) + 1 = 4(x - 3)^2 + 1

is discarded

The vertex form of a quadratic equation is f(x) = c*(x - h)^2 + k, where c, h and k are all constant, and point (h,k) is the vertex of the quadratic function. If c > 0, then the vertex is a minimum and if c < 0 then the vertex is a maximum. Therefore, options:

g(x) = –9(x2 + 2x + 1) – 7 = -9(x + 1)^2 - 7

g(x) = –3(x2 – 8x + 16) – 6 = -3(x - 4)^2 - 6

are dicarded

In consequence, the correct option is:

g(x) = 8(x2 – 6x + 9) – 5 = 8(x - 3)^2 - 5

Answer:

The last choice is the one you want

Step-by-step explanation:

First of all, a parabola has a minimum value if it is a positive parabola, one that opens upward. The first and the third parabolas are negative so they open upside down. That leaves us with choices 2 and 4. We find the side to side and up or down movement by finishing the completion of the square that has already been started for us. Do this by factoring what's inside the parenthesis into a perfect square binomial.

The second one factored becomes:

$g(x)=4(x-3)^2+1$

which reflects a shift to the right 3 and up 1. Not what we are asked to find.

The fourth one factored becomes:

$g(x)=8(x-3)^2-5$

which reflects a shift to the right 3 and down 5. That's what we want!

3. Through what angle does the minute hand of a clock turn in 12 minutes of time?

Answers

60 minutes=360º
Then:

360º---------------60 minutes
x--------------------12 minutes

x=(360º * 12 minutes) / 60 minutes=72º

answer: 72º

60 minutes=360º
Then:

360º---------------60 minutes
x--------------------12 minutes

x=(360º * 12 minutes) / 60 minutes=72º

answer: 72º
