Answer:

x =34

Step-by-step explanation:

The sum of the angles of a triangle add to 180

The two angles in the middle are vertical angles to they are both 56 degrees

56+x+90 = 180

Combine like terms

146 +x = 180

Subtract 146 from each side

146-146 +x = 180-146

x = 34

h= k/j

Multiply by j for the left and right hand side

(h)(j)= k/j(j)

Cross out j and j for the right hand side.

hj= k

answer is : k= hj

I think this is the answer

ANSWER

[tex]k = hj[/tex]

EXPLANATION

The given formula is:

[tex]h = \frac{k}{j} [/tex]

We want to solve this formula for k.

Let us multiply both sides by j.

[tex]h \times j = \frac{k}{j} \times j[/tex]

Cancel the common factors.

[tex]hj = k[/tex]

Or we rewrite to obtain,

[tex]k = hj[/tex]

k is now isolated on one side of the equation.

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:

[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.

43/60 would be the probability

The required estimation is [tex]P(A)=\frac{43}{60}[/tex]

Important information:

Number of observation=60

Number of expected outcomes =43

Probability: Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed between zero and one. So, the formula probability is,

P(A)=Expected observation/number of observations

Now, substituting the given values into the above formula we get,

The midline is usually at y = 0.  In the given equation, the graph is shifted down 4 units so the new midline is at -4.

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.

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

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]

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

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: [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]

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

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.

Step-by-step explanation:

This is a question on probability, which means that we can find:

# of wanted outcomes/total outcomes.

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

Simplify: 1/5

So 1/5 of donuts Vicky eats will probably be cake donuts.

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.
