Answer: 15 sq. units

Step-by-step explanation:

Given

[tex]f(x)=\ln (2)2^x[/tex]

The area bound by it from x=0 to x=4

Using integration

[tex]I=\int_{0}^{4}f(x)dx[/tex]

[tex]I=\int_{0}^{4}\ln(2)2^xdx[/tex]

[tex]I=\left [ \dfrac{\ln (2)2^x}{\ln (2)} \right ]_0^4[/tex]

[tex]I=\left [ 2^x \right ]_0^4[/tex]

[tex]I=2^4-2^0\\I=16-1=15\ sq.units[/tex]

Answer:

x=NEGATIVE 1/2, POSITIVE 2

Step-by-step explanation:

Just use math.waycom

The non-negative zero of the function f(x) is x = 2.

The zero of the function is where the y-value is zero. The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.

here, we have,

For a given function f(x), the "zeros" of the function are the values of x such that:

f(x) = 0

In this case, we have the function:

f(x) = 6*x^2 - 9*x - 6

If we want to find the zeros of this function, we need to solve:

f(x) = 0 =  6*x^2 - 9*x - 6

To solve this, we can use the Bhaskara's formula, which says that for a general quadratic equation:

0 = a*x^2 + b*x + c

The zeros are:

x = -b ±√b² - 4ac / 2a

In this case our equation is:

0 =  6*x^2 - 9*x - 6

then, in the above notation, we have:

a = 6

b = -9

c = -6

Replacing these in our general formula, we get:

x = 9±15 /12

Then we have two zeros:

x = (9 + 15)/12 = 24/12 = 2

x = (9 - 15)/12 = -6/12 = -1/2

But we want only the non-negative, so we can discard the second one.

Concluding, the non-negative zero of the function f(x) is x = 2.

Answer:

They are both correct. When the fractions are added, the sum is 4/6. 4/6 is not in its simplest form yet. It can be simplified by dividing the numerator and the denominator by 2. When divided by 2, it yields 2/3

Step-by-step explanation:

[tex]\frac{1}{2}[/tex] + [tex]\frac{1}{6}[/tex]

[tex]\frac{3 + 1}{6}[/tex] = 4/6 = 2/3

Answer:

27/4

Step-by-step explanation:

In this question,

[tex]x = 3 \\ y = - 1[/tex]

So if we substitute this in the equation given below

[tex] {x}^{3} \div 3 - y[/tex]

So if we substitute the variables,

[tex] {3}^{3} \div 3 - ( - 1) \\ [/tex]

[tex]27 \div 4[/tex]

[tex] \frac{27}{4} [/tex]

Answer:

Step-by-step explanation:

Ratio = 4/7 : 1/8

        [tex]=\frac{\frac{4}{7}}{\frac{1}{8}}\\\\=\frac{4}{7}*\frac{8}{1}\\\\=\frac{32}{7}[/tex]

       = 32 : 7

[tex]\frac{\frac{1}{8}}{\frac{4}{7}}=\frac{1}{8}*\frac{7}{4}\\\\=\frac{7}{32}[/tex]

= 7 : 32

Ratio 4/7 over 1/8  is the multiplicative inverse of the ratio 1/8 over 4/7

Answer:

35*2 = 70

70 mph on the Major Highway

Step-by-step explanation:

Answer:

70

Step-by-step explanation:

if 35 is half of x (x being the speed of a major interstate highway a few miles away) then this means [tex]\frac{x}{2} =35[/tex] you multipliy both sides by 2 to get x by its self and now have x=70

Answer:

128 servings

Step-by-step explanation:

16 cups in a gallon

1.25 cups /10 servings = .125 cups per serving

16 cups / .125 = 128 servings

The slope is 12 and y- intercept is -5.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

y=12x−5

Now, from slope- intercept form

y = mx + b

where m is the slope and b is the y intercept.

Now, Comparing with given equation

m= 12 and b= -5

Hence, the slope is 12 and y- intercept is -5.

Answer:

m<ACD = [tex]50^{o}[/tex]

Step-by-step explanation:

From the question given, ΔACD is a right angled triangle. Then we can apply one of the properties of a triangle to it.

In the triangle ACD:

<ACD + <DAC + <ADC = 180 (sum of angles in a triangle)

<ACD + 40 + 90 = 180

<ACD + 130 = 180

<ACD = 180 - 130

<ACD = [tex]50^{o}[/tex]

With the application of the property of the sum of interior angles of a triangle, the measure of <ACD is [tex]50^{o}[/tex].

Answer:

7/20

Step-by-step explanation:

Let the total probability be 1;

Given

Probability of selecting a red M&M = 2/5,

Probability of selecting a green M&M = 1/4

Required

Probability of selecting a white M&M

Probability of selecting a white M&M = 1 - (2/5+1/4)

Probability of selecting a green M&M = 1 - (4(2)+5(1)/20)

Probability of selecting a green M&M = 1 - (8+5/20)

Probability of selecting a green M&M  = 1 - 13/20

Probability of selecting a green M&M  = 7/20

hence the Probability of selecting a green M&M is 7/20
