Answer:

Option C is correct.

The exponential grows at twice the rate of the quadratic.

Step-by-step explanation:

Slope(rate) is given by:

\text{Slope} = \frac{y_2-y_1}{x_2-x_1}

As per the statement:

An exponential function and a quadratic function are graphed below.

In the given interval: [0, 1]

In Exponential function  graph

Consider points (0, 1) and (1, 2)

then by definition  of slope we have;

\text{Slope} = \frac{2-0}{1-0} = \frac{2}{1} = 2

⇒Rate of exponential function is 2

In Quadratic function graph:

Consider points (0, 0) and (1, 1)

then by definition  of slope we have;

\text{Slope} = \frac{1-0}{1-0} = \frac{1}{1} = 1

⇒Rate of quadratic function is 1

⇒\text{Rate of exponential function} = 2 \cdot \text{rate of quadratic fucntion}

Therefore, the exponential grows at twice the rate of the quadratic.

Find the vertex, focus, directrix, and focal width of the parabola. negative 1 divided by 12 times x squared = y
notka56 [123]

negative 1 divided by 12 times x squared = y

\frac{-1}{12} x^2=y

To find vertex we use formula x= -b/2a

From the given equation a= -1/12  and b =0

Plug in the values in the formula

x= \frac{0}{\frac{-1}{12}} =0

Now plug in x=0 in the given equation and find out y

\frac{-1}{12}(0)^2=y

So y=0

Hence vertex is (0,0), h=0  and k =0

Focus is (h, k+p)

We need to find out p

We know a= -1/12

p = 1/4a

p = \frac{1}{4\frac{-1}{12}} = -3

So focus is (0,0-3) that is (0, -3)

Directrix is y = k - p

We know p = -3  and k=0

y = 0 -(-3) = 3. so directrix is y = 3

Focal width = |4p|

We know p = -3

so it becomes |4(-3)| = 12

Focal width = 12

HELP PLZ ASAP<br> whats the least common denominator if 1/8, 5/12, and 7/18 A.216 B.108 C.72 D.48
yanalaym [24]

Answer:

LCD = 72

Equivalent Fractions with the LCD

1/8 = 9/72

5/12= 30/72

7/18 = 28/72

Solution:

Rewriting input as fractions if necessary:

1/8, 5/12, 7/18

For the denominators (8, 12, 18) the least common multiple (LCM) is 72.

LCM(8, 12, 18)

Therefore, the least common denominator (LCD) is 72.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1/8 = 1/8 × 9/9 = 9/72

5/12 = 5/12 × 6/6 = 30/72

7/18 = 7/18 × 4/4 = 28/72

A, B, and C are collinear points. B is between A and C. AB = 5x + 8 BC = 6x - 1 AC = 12x - 11 Find AC.
Vlada [557]

Answer:

AC = 198

Step-by-step explanation:

Since all these points are collinear, we know that the addition of AB plus BC should give the same as AC. We can then set an equation that addresses this identity:

AB + BC = AC

5x +8 +6x - 1 = 12x - 11

Now re-arranging like terms in order to combine them:

8 - 1 + 11 = 12x - 5x - 6x

19 - 1  = 12x - 11x

18 = x

Now that we know the value of 'x", we can determine the value of AC:

AC = 12x - 11

AC = 12 (18) - 11

AC = 216 - 18

AC = 198

In the 1980s land prices in Japan surged upward in a ""speculative bubble."" Land prices then fell for 11 straight years between
Aloiza [94]

Answer:

Step-by-step explanation:

Given the supply of land is perfectly inelastic, the drop in prices must have resulted from decreased demand for land. The demand for land would fall if there were less of a return on the land (i.e., rent), so we can safely assume that land rent fell in Japan between 1990 and 2001. The shifts from D3 to D2 to D1 demonstrate graphically what happened in Japan.

When solving a quadratic equation using the quadratic formula, the value of the discriminant is 49. How many and what type of so
musickatia [10]

Answer: 2 rational solutions

Step-by-step explanation:

When the discriminant,  b² + 2a,  is greater than 0, there are two real solutions. 49 is the perfect square of 7, so the solutions are also rational: plus and minus 7
