The equation of a vertical parabola in vertex form is equal to

f(x)= a(xh)² + k

where

a is a coefficient

(h,k) is the vertex

we have

f)x) = x² + 12x + 6

Convert to vertex form

Complete the square

f)x) 6= x² + 12x

f)x) - 6+36= (x² + 12x +36)

f)x)+ 30 = (x² + 12x +36) -

f)x)+30= (x+6)²

f)x) = (x+6)² – 30. -----> equation in vertex form

therefore

The vertex is the point (-6,-30)

h=-6, k=-30

There were some adults and children at the party. For every 3 adults, there 11 children. There were 32 more children than adults. How many adults were at the party?

Answers

Answer:

12 adults

Step-by-step explanation:

Given that :

Let :

Number of children = x

Number of adult = y

x = 32 + y - - - - - (1)

Ratio of adult to children

3 : 11

x = (11/3)y - - - (2)

Put x = 11/3y in (1)

(11/3)y = 32 + y

11y/3 - y = 32

(11y - 3y) / 3 = 32

11y - 3y = 32 * 3

8y = 96

y = 96/8

y = 12

Hence, number of adults = 12

help please i’m so desperate

Answers

You're fairly close but not 100% correct.

This function is logarithmic simply because of the presence of "log" in the notation. So you're correct with that statement.

However, we have a vertical asymptote and not a horizontal one. Note how the green function approaches but never touches x = 2. This is a vertical electric fence of sorts. This is due to the fact that log(x) cannot have x = 0. So log(x-2) cannot have x = 2. We can't have x < 2 either.

So you'll need to change that '3' to '2' without quotes of course.

The range is correct. The function can spit out any y value we want. So the range is the set of all real numbers, or we could say -infinity < y < infinity which translates to the interval notation you wrote. The function is increasing because we're going uphill when moving to the right.

The domain is not correct. The domain would be x > 2 to represent the possible x inputs. We can plug in anything larger than 2. The inequality x > 2 translates to the interval notation [tex](2, \infty)[/tex]

The end behavior portion is half correct. The left side end behavior should be [tex]\text{ as } x \to 2, \ y \to -\infty[/tex] to represent the idea of getting closer to that electric fence and going off to negative infinity (down the page forever). We don't have x approaching negative infinity because we can't go beyond that fence. The end behavior on the right side is correct.

-------------------

So the answers would be

The function f(x) is a logarithmic function with a vertical asymptote x = 2. The range of the function is [tex](-\infty, \infty)[/tex] and it is increasing on its domain of [tex](2, \infty)[/tex]. The end behavior on the left side is [tex]\text{ as } x \to 2, \ y \to -\infty[/tex] and the end behavior on the right side is [tex]\text{ as } x \to \infty, \ y \to \infty[/tex]

Answer:

5,200

Step-by-step explanation:

6, 10, 14, ...

Sum = [ number of terms(first term+last term) ] / 2

-we know there are 50 terms

-we now the first term is 6

-we need to find the last term

last term = first term + (n-1)* difference between first and second term

last term = 6 + (50-1) * (10-6)

last term = 6 + 49*4 = 202

Sum = [ number of terms(first term+last term) ] / 2

Sum = [ 50 ( 6 + 202) ] / 2 = 5,200

unit rate in dollars per

minute = Total amount Sarah earns / Time taken to earn

= 45 1/2 ÷ 5 3/4

= 91/2 ÷ 23/4

a room in a form of a cuboid has a length of 5cm, height 8cm and breadth 0.07m. if one person can occupy a volume of 14cm3(cube). what is the maximum number of people needed to fill the room​

Answers

Answer:

20 people

Step-by-step explanation:

The volume of a cuboid is equal to length * breadth * height.

First, we want to figure out the values relative to each other. Everything is in centimeters except the breadth, which is 0.07m. To convert meters to centimeters, we can multiply by 100: 0.07 * 100 = 7, so the breadth is 7cm.

Next, the volume is  length * breadth * height = 5cm * 7cm * 8cm = 280cm³. Each person occupies 14cm³. To find how many people can occupy the cube, we can divide the volume by the space each person takes, so

280cm³/14cm³ = 20 people

Note that we can divide because each person takes x amount of space, and the total space, z, can be represented by x * y = z, with y representing the amount of people, because we add x space for each person. Dividing both sides by x, we get y = z/x

A 240hp automobile engine delivers 195hp to the drive wheels, what is the effciency of the transmission and drive mechanism?

Answers

Answer:

81.25%

Step-by-step explanation:

Given that :

Engine power = 240 hp

Power delivered to drive wheel = 195 hp

Efficiency = (power delivered to drive wheel / Engine power) * 100%

Efficiency = (195 / 240) * 100%

Efficiency = 0.8125 * 100%

Efficiency = 81.25%

The efficiency of transmission and drive mechanism is 81.25%

What is the y-intercept of the line 2x-4y=8

Answers

Answer:

The y intercept is -2

Step-by-step explanation:

Hi there!

We want to find the y-intercept of the line 2x-4y=8

The y-intercept is the point in where the line passes through the y axis. This means that the value of x at the y intercept is 0.

So substitute 0 as x into the equation

2(0)-4y=8

Multiply

0-4y=8

Simplify

-4y=8

Divide both sides by -2

y=-2

The y intercept is -2. If you need it as a point, it's (0, -2)

12°=2x

12°÷2=2x÷2

6°=x

therefore x=6°

Step-by-step explanation:

hope this is helpful

Answer:

x = 6

Step-by-step explanation:

The 2 angles are vertically opposite and are congruent, so

5x + 100 = 3x + 112 ( subtract 3x from both sides )

2x + 100 = 112 ( subtract 100 from both sides )

2x = 12 ( divide both sides by 2 )

x = 6
