PLS HELP!!! Which of the following function graphs have a range of (-∞, ∞)?

Answer:

5g(g + 8) + 3(g + 8)

5g² + 40g + 3g + 24

5g² + 43g +24

Answer:

6.5

Step-by-step explanation:

Answer:

6.5

Step-by-step explanation:

Using a calculator, if you typed in 52 divided by 8, you'd get 6.5. You could also express 52/8 as a mixed fraction: 6 4/8. If you look at the mixed fraction 6 4/8, you'll see that the numerator is the same as the remainder (4), the denominator is our original divisor (8), and the whole number is our final answer (6).

Answer:

width is 7, length is 14

Step-by-step explanation:

x(x+7) = 98

x^2 + 7x = 98

x^2 + 7x - 98 = 0

( x   +   14 )( x  -   7 ) = 0

x+14=0 results in negative measures

x-7=0 ---> x= 7

width is 7, length is 14

Answer:

5i

Step-by-step explanation:

i² = -1

[tex]\sqrt{-25}[/tex] = [tex]\sqrt{i^{2} 25 }[/tex]

         = [tex]\sqrt{i^{2} }[/tex] ·[tex]\sqrt{25}[/tex]

          = i · 5

          = 5i

Answer:

1527.1

Step-by-step explanation:

The formula is:

[tex]l=r2+h2[/tex]

and

[tex]V=πr2*h/3[/tex]

Using probability concepts, it is found that P(X) = 0.68.

The probabilities given are:

Event X is the probability of living in either South America, Asia or Europe, thus it's probability is the sum of these three probabilities, that is:

[tex]P(X) = 0.06 + 0.55 + 0.07 = 0.68[/tex]

Hence, P(X) = 0.68.

A similar problem is given at https://brainly.com/question/25227627

Answer:

0.68

explanation:

you're adding the numbers on the graph together

South America = 0.06

Europe = 0.07

Asia = 0.55

0.06 + 0.07 + 0.55 = 0.68

Answer:

50 L of petrol is needed to travel 600 km.

Step-by-step explanation:

The car travels 1 km in 20/240 L of petrol.  

Then,  

Petrol needed to travel 600 km  

20/240 × 600  

20/24 × 60  

20/4 × 10  

5 × 10

= 50 L

Answer:

50 liters

Step-by-step explanation:

Petrol needed to travel 240 Km = 20 liters

Petrol needed to travel 1 Km = 20/240

Petrol needed to travel 600 Km = [tex]\frac{20}{240} * 600[/tex]

      = 50 liters

Answer:

  B 12.5%

Step-by-step explanation:

The percentage change is calculated as ...

  % change = ((new value)/(old value) -1) × 100%

  = (36/32 -1) × 100% = 1/8 × 100% = 12.5%

Peter increased his crunches by 12.5%.

Step-by-step explanation:

y  =2/3x  +  1/3

slope 2/3

y-intercept:   (0  ,1/  3)

Answer:

Step-by-step explanation:

- 2x + 3y = -1​ is the equation of a line

Pick any values for x then find y or for y and then find x;

if you have two points you can draw a line trough those two points.

For example,

pick x= -1 then find y

- 2*(-1) + 3y = -1​

         2+ 3y = -1

              3y = -1-2

                y= -3/3

                y= -1

First point has the coordinates (-1, -1)

pick y = 1 then find x

- 2x + 3*1  = -1​

      -2x +3 = -1

           -2x = -1-3

            -2x = -4

                x= -4/-2

                x= 2

Second point has the coordinate (2, 1)

Draw a line trough the points (-1, -1) and (2,1) to sketch the graph of -2x+3y = -1

Step-by-step explanation:

√(6+x−x²)=9

the domain :

6+x-x² ≥ 0

(3-x)(2+x) ≥0

-2 ≤ x ≤ 3

problem solving:

√(6+x−x²)=9

6+x−x²=81

-x²+x+6-81 = 0

-x²+x-75 = 0

x²-x+75 = 0

D = 1² -4(1)(75) = 1-300 = -299

since D < 0, the equation doesn't have any real numbers solution

Answer: No, it is linear

Explanation: The constant is +8, meaning the y intercept is 8. Proportional lines go through (0,0), but this line goes through (0,8).

Answer:

Move it 2 places to the right.

Step-by-step explanation:

The magnitude of the exponent of 10 tell you how many places to move

The sign of the exponent of 10 tells you the direction.

Positive, decimal moves right.

Negative, decimal moves left.

Answer:

  7%

Step-by-step explanation:

The simple interest formula is ...

  I = Prt . . . . where P is the principal, r is the rate, and t is the number of years

Filling in the given values, we can solve for r.

  490 = 1400·r·5

  490/7000 = r = 0.07 = 7%

The interest rate was 7%.

Answer:

tan^2 60 - sin^2 45

= (√3)^2- (1/√2)^2

= 3-1/2

= 6-1/2

= 5/2

Answer:

[tex]\frac{5}{2}[/tex]

Step-by-step explanation:

The exact value of tan(60) is sqrt(3), and sin(45) is 1/sqrt(2)

tan^2 (60) - sin^2 (45)

[tex]=(\sqrt{3})^2-(\frac{1}{\sqrt{2}} )^2\\=3-\frac{1}{2}\\ = \frac{5}{2}[/tex]

Answer:

The function has a negative leading coefficient and a maximum vertex point

Explanation:

This function's leading coefficient is determined by whether it is concave up or concave down, meaning it has an Up and Up end behavior for a positive leading coefficient and a Down and Down end behavior for a negative coefficient.

This function's end behavior is Down and Down, so it must have a negative leading coefficient.

The function has a minimum vertex when the function has a positive leading coefficient and a maximum vertex point when the function has a negative leading coefficient.

This means that the functions vertex is the highest or lowest possible value of the function (the rest of the function continues forever in whichever direction.

This particular function has a maximum vertex as there is no point above the vertex here and the function has a negative leading coefficient.

Answer:

Leading coefficient: negative

Maximum vertex point
