Answer:

The top-right graph.

Step-by-step explanation:

Because f(-2) = 0.

The graph which represents the non-linear function with power 1/3 is similar graph in right side of upper option. Thus, the option B is correct.

When the graph of the function represents the straight line, then it is called the linear function.

The graph of a function in which the power of variable is more than one is called the non-linear graph.

The function given in the problem is,

f(x)=∛(x+2)

It is a non-linear function. This function can be written as,

[tex]f(x)=(x+2)^\dfrac{1}{3}[/tex]

The graph of this function is attached below. This graph passes from the point (-2,0) and (0,1.26) and looks similar to the option B (right side of upper option).

Hence, the graph which represents the non-linear function with power 1/3 is similar graph in right side of upper option. Thus, the option B is correct.

Answer:

The remainder is 0 ⇒ 3rd answer

Step-by-step explanation:

* In the synthetic calculation we use the coefficient of the dividend

  with the value of x when the divisor = 0

∵ x - 1 = 0 ⇒ add 1 to both sides

∴ x = 1  

Step 1 : Write down the coefficients of the f(x) , put x = 1 at the left

Answer:

Step-by-step explanation:

[tex]\csc B=\dfrac{1}{\sin B}\\\\-1\leq\sin B\leq1,\ \text{therefore}\ \csc B\leq-1\ or\ \csc B\geq1\\\\-1.75\leq-1\\\\0.5\to \bold{ANSWER}\\\\1\geq1\\\\1.05\geq1[/tex]

By definition, the cosecant is the inverse of the sine:

[tex]\csc(x) = \dfrac{1}{\sin(x)}[/tex]

Since the sine is never more than 1, the cosecant can never be smaller than 1.

So, the only impossible option is 0.5.

Answer:

Step-by-step explanation:

So, we know that this inequality has an "at most" in its phrase, therefore signifying the sign x ≤ 5. Since the x is in the left side without any negatives, so the arrow goes left, and the circle is filled. So, B.

Answer: [tex]tan(x)=\±\frac{3}{4}[/tex]

Step-by-step explanation:

You know that [tex]sin(x)=\frac{3}{5}[/tex] and you can identify that. Then:

[tex]sin^2(x)=(\frac{3}{5})^2[/tex]

[tex]sin^2(x)=\frac{9}{25}[/tex]

Remember that:

[tex]cos^2(x)=1-sin^2(x)[/tex]

Then [tex]cos^2(x)[/tex] is:

[tex]cos^2(x)=1-\frac{9}{25}\\\\cos^2(x)=\frac{16}{25}[/tex]

Apply square root to both sides to find cos(x):

[tex]\sqrt{cos^2(x)}=\±\sqrt{\frac{16}{25}}\\cos(x)=\±\frac{4}{5}[/tex]

Remember that:

[tex]tan(x)=\frac{sin(x)}{cos(x)}[/tex]

Then, this is:

[tex]tan(x)=\frac{\frac{3}{5}}{\±\frac{4}{5}}[/tex]

[tex]tan(x)=\±\frac{3}{4}[/tex]

Answer:

14 five-dollar bills

Step-by-step explanation:

Let

x-----> the number of five-dollar bills

y----> the number of twenty-dollar bills

we know that

x+y=32 ----> y=32-x ----> equation A

5x+20y=430 ----> equation B

Substitute equation A in equation B and solve for x

5x+20(32-x)=430

5x+640-20x=430

20x-5x=640-430

15x=210

x=14 five-dollar bills

Find the value of y

y=32-x ----> y=32-14=18 twenty-dollar bills

Answer: Associative property of addition.

Step-by-step explanation:

The rule for the Associative property of addition is:

[tex]a + (b + c) = (a + b) + c[/tex]

Therefore, this property establishes that it does not matter how you group the numbers, the sum will not change.

You can observe that, in this case, the numbers of the given addition can be grouped as [tex]6 + (14 + 70)[/tex] or [tex](6 + 14) + 70[/tex], and the sum will be the same.

Then, you get:

[tex]6 + (14 + 70) = (6 + 14) + 70 = 20 + 70 = 90[/tex]

Answer:

Step-by-step explanation:

To evaluate h(j(2)) substitute x = 2 into j(x) then substitute the value obtained into h(x)

j(2) = - 2 × 2 = - 4, then

h(- 4) = (3 × - 4) - 1 = - 12 - 1 = - 13

Hence h(j(2)) = - 13

{7,8}

Answer:

see explanation

Step-by-step explanation:

Subtract [tex]\frac{2}{3x}[/tex] from both sides

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

Cross- multiply

3x = 12 ( divide both sides by 3 )

x = 4

As a check

Substitute x = 4 into the equation and if both sides are equal then it is the solution.

left side

[tex]\frac{2}{12}[/tex] + [tex]\frac{1}{6}[/tex] = [tex]\frac{1}{6}[/tex] + [tex]\frac{1}{6}[/tex] = [tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]

right side

[tex]\frac{4}{12}[/tex] = [tex]\frac{1}{3}[/tex]

Both sides are equal hence x = 4 is the solution

Answer:

m = 1/3

Step-by-step explanation:

When you multiply by a fraction it's actually dividing.

:)

The variable m equals 1/3 for the equation 2 = 6m obtained by dividing both sides by 6.

The given equation is 2=6m.

m is the variable in the equation.

To determine the value of m in the equation 2 = 6m, we need to isolate the variable m.

Divide both sides of the equation by 6:

2/6 = (6m)/6

1/3 = m

Therefore, m equals 1/3.

Find the difference between 45 and 55:

55-45 = 10

Find the difference between the mpg for 45 and 55:

35 - 34.1 = 0.9

Divide the difference in mpg by the difference in x:

0.9 / 10 = 0.09

The answer is B.

Answer:

Option B: 0.09 mpg/mph

Step-by-step explanation:

You divide the delta (=difference) in F by the delta in x:

delta F is 35.0-34.1 = 0.9

delta x = 55-45 = 10

so rate of change is 0.9/10 = 0.09, answer B

ANSWER

(f.g)(x)

EXPLANATION

From the table we can observe the following patterns:

f(-6)=12

g(-6)=-6

h(-6)=-72=12×-6

f(0)=3

g(0)=0

h(0)=0=3×0

f(6)=-6

g(6)=6

h(6)=-36=-6×6

Hence the h(x) is obtained by multiplying f(x) by g(x).

h(x)=(f.g)(x)

To find the equation of the circle with a given point (1,-7) and center (-6,-4), calculate the radius using the distance formula to find that the radius is √58, then substitute the center coordinates and radius into the standard circle equation to get (x + 6)² + (y + 4)² = 58.

To write the equation of the circle given a point on the circle at (1,-7) and the center at (-6,-4), we will use the standard form of the circle's equation (x-h)² + (y-k)² = r², where (h, k) is the center of the circle and r is the radius. First, we calculate the radius of the circle using the distance formula: r =
√[(x_2-x_1)² + (y_2-y_1)²]. Plugging in our values, we get r = √[(1 - (-6))² + (-7 - (-4))²] = √[49 + 9] = √58. Therefore, the equation of the circle with center (-6,-4) and passing through the point (1,-7) is (x + 6)² + (y + 4)² = 58.

Wanted outcomes: Vicky ate 3 cake donuts, so our value is 3.

Total outcomes: Vickey ate 3 + 4 + 8 = 15 donuts, so our value is 15.

Plug in: 3/15
