Answer 1
Answer:

Answer:

the number is 4

Step-by-step explanation:

we can write this as

x + 15 = 19

now we transpose

x= 19-15

x= 4

Faucet a can fill a water cooler 8 minutes. faucet b can fill the same cooler in 12 minutes. how long will it take both faucets together to fill the water cooler?

Answers

This is a work problem. We can use theories on ratios and proportion in order to solve this. We do as follows:

Faucet A = 8 minutes to fill
Faucet B = 12 minutes to fill

1/8 + 1/12 = 1/x

let x represent the time it takes for both to fill the cooler

x = 4.8 minutes for  both to fill the cooler

Functions f(x) and g(x) are shown below:f(x) = x2
g(x) = x2 − 8x + 16

In which direction and by how many units should f(x) be shifted to obtain g(x)?

Left by 4 units
Right by 4 units
Left by 8 units
Right by 8 units

Answers

Answer:  The answer is (B) Right by 4 units.

Step-by-step explanation:  The two functions f(x) and g(x) are defined as follows:

f(x)=x^2,\n\ng(x)=x^2-8x+16.

We are to check the correct transformation  of the graph of f(x) to the graph of g(x).

We can rewrite the graph of g(x) as follows:

g(x)=x^2-8x+16=x^2-2* x* 4+4^2=(x-4)^2.

Comparing this with the equation of f(x), we can say that f(x) is shifted right by 4 units to obtain g(x).

The graphs of both the functions are shown in the attached figure.

A figure skater needs a total score of at least 90 to move on to the next round. The total score is the average of four judges’ scores. The first three judges’ scores were 83, 88, and 92. The figure skater made it to the next round. What is the minimum score the fourth judge could have given? Enter your answer in the box.

Answers

It would be 83+88+92+x/4 = 90

263 +x = 360

x = 360-263

x=97

Which of the following equations is of a parabola with a vertex at (0, -3)?y = (x - 3)^2
y = (x + 3)^2
y = x^2 - 3
y = x^2 + 3

Answers

Answer: Third option is correct.

Step-by-step explanation:

Since we have given that

We need a parabola with a vertex at (0,-3)

If we select the equation:

y = x^2 - 3

When we put x = 0, we get

y=0-3\n\ny=-3

And similarly, when we put y = -3, we get

-3=x^2-3\n\n0=x^2\n\nx=0

Hence, third option is correct.
The\ vertx\ form:y=a(x-h)^2+k\nwhere\ the\ coordinates\ of\ vertex\ are\ (h;\ k)\n\n-------------------------\n\nvertex:(0;-3)\n\ny=a(x-0)^2+(-3)=ax^2-3\n\nif\ a=1\ then\ y=x^2-3\leftarrow answer
