Answer:

For acute angles, remember what sine means: opposite over hypotenuse. If we increase the angle, then the opposite side gets larger. That means "opposite/hypotenuse" gets larger or increases.

Step by Step:

Keep this in mind >>

Consider the unit circle > The sine and cosine ratios are the only ratios that have 1 (the radius or hypotenuse) as the denominator. The numerators (sides) vary between 0 and 1, thus determining that the sine and cosine do the same.

All of the other ratios (tangent, cotangent, secant, cosecant) have a side as the denominator, varying between 0 and 1. As any denominator approaches 0, the value of the ratio approaches infinity.

ACF is a 30º-60º-90º triangle because of the following:

1) Based on a theorem, in a 30°-60°-90° triangle the sides are in the ratio 1 : 2 : \(\sqrt{3}\)

1 → short leg

2 → hypotenuse

\(\sqrt{3}\) → long leg

Side length of the hexagon is the short leg of the triangle. It is 1.

r1 is the radius of the incircle in a regular hexagon. 2(r1) is the diameter of the incircle. It is also the hypotenuse of the right triangle. It is 2.

Using Pythagorean theorem.

\(a^2 + b^2 = c^2\)

\(1^2 + b^2 = 2^2\)

\(b^2 = 2^2 - 1^2\)

\(b^2 = 4 - 1\)

\(b^2 = 3\)

\(\sqrt{b^2} = \sqrt{3}\)

\(b = \sqrt{3}\)

Answer:A

Step-by-step explanation:

The items of worth $600,000,000 should be purchased in the state to meet the requirement, the correct option is A.

An equation is a mathematical statement that is formed when two algebraic expressions are equated using an equal sign.

The state has predicted to get $24 million from the state lottery,

The amount from property tax is $32 million

The amount form excise tax is $14 million

The state needs $100 million to cover its expenses

A sales tax of 5% is charged by the state

Let the total sales is $x in million dollars then the equation that can be formed is

24 + 32 +14 +(5/100 ) * x = 100

70+ (5/100 ) * x = 100

(5/100 ) * x = 100 -70

(5/100 ) * x = 30

x = 30 * 100 / 5

x = $600,000,000

Answer:

∠1 is 150°

∠2 is 30°

∠3 is 150°

∠4 is 30°

Step-by-step explanation:

∠1 is vertically opposite to ∠3 so they are equal

360° - (150° + 150°) = 360° - 300° = 60°

∠2 and ∠4 must sum to 60°

Step-by-step explanation:

From the question

∠1 is opposite to ∠ 3 and vertically opposite angles are equal

So

∠1 = ∠ 3

That's

∠ 3 and ∠ 4 are on a straight line and angles on a straight line add up to 180°

So to find ∠4, subtract ∠3 from 180°

That's

∠ 4 = 180 - ∠ 3

∠ 4 = 180 - 150

Since ∠ 4 and ∠ 2 are opposite they are also equal

That's

∠ 4 = ∠ 2

Therefore

End Balance: $3,839.25 + $2,579.20 - $2,190.05 = $5,735.15, so the reconciled balance of $5,735.15.

This theory is used to compare the bank statements to the check register in order to properly reconcile the two balances.

The theory used in this question is the bank reconciliation theory.

Step 1: Begin by looking at the two balances - the check register balance and the bank statement balance.

In this case, the check register balance is $3,839.25 and the bank statement balance is $3,450.10.

Step 2: Add up all of the deposits that are not reported on the bank statement. In this case, the deposits are $2,000, $135.67, $254.77, and $188.76.

Step 3: Subtract all of the checks that are not reported on the bank statement. In this case, the checks are $567.89, $23.83, $598.33, and $1,000.

Step 4: Add the deposits and subtract the checks from the check register balance.

In this case, the check register balance ($3,839.25) plus the deposits ($2,579.20) minus the checks ($2,190.05) gives a reconciled balance of $5,735.15.

The first option is the correct one for the line y = x - 2:

" coordinate plane with a line starting at (negative 2, negative 4), passing through (0, negative 2)"

Here we want to identify the graph of the linear equation:

y = x - 2

First, notice that when we evaluate this in x = 0 we get the y-intercept:

y = 0 - 2

y = -2

Then the y-intercept there is (0, -2)

Also, evaluating the linear equation in x = -2, then we will get:

y = -2 - 2

y = -4

So we have the point (-2, -4)

The surface area of an ice cube with 4 cm sides is 96 square centimeters.

It is a measurement of the sum of all the areas of the faces, sides, and any other surfaces of an object. For example, a cube has six square faces, each with the same area.

To find the surface area of an ice cube with 4 cm sides, we need to add up the areas of all six faces. Each face is a square with side length 4 cm, so the area of each face is:

Area of one face = (side length)² = 4 cm × 4 cm = 16 cm²

Since there are six faces on a cube, the total surface area of the ice cube is:

Total surface area = 6 × (area of one face) = 6 × 16 cm² = 96 cm²

Therefore, the surface area of an ice cube with 4 cm sides is 96 square centimeters.

Answer:

≈ 0.22

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 0.875 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 0.875 is 100%, so we can write it down as 0.875=100%.

4. We know, that x is 25% of the output value, so we can write it down as x=25%.

5. Now we have two simple equations:

1) 0.875=100%

2) x=25%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

0.875/x=100%/25%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 25% of 0.875

0.875/x=100/25

(0.875/x)*x=(100/25)*x       - we multiply both sides of the equation by x

0.875=4*x       - we divide both sides of the equation by (4) to get x

0.875/4=x

0.21875=x

x=0.21875

now we have:

25% of 0.875=0.21875

Given:

In triangle XYZ, x = 27 cm, y = 79 cm and \(\angle C=142^\circ\).

To find:

The length of z.

Solution:

In triangle XYZ, using the Law of cosine, we get

\(z^2=x^2+y^2-2xy\cos Z\)

Putting the given values in the above formula, we get

\(z^2=(27)^2+(79)^2-2(27)(79)\cos (142^\circ)\)

\(z^2=729+6241-4266(-0.788)\)

\(z^2=6970+3361.608\)

\(z^2=10331.608\)

Taking square root on both sides.

\(z=\pm \sqrt{10331.608}\)

\(z=\pm 101.6445178\)

Approx the above value to the nearest number and side length cannot be negative. So,

\(z\approx \pm 102\text{ cm}\)

Therefore, the length of z is about 102 cm.

The necessary equations for the lines are y = 5/3x, y = -3/4x, and y = -4x, respectively, which cross the y axis at the point (-3, -5), (-4, 3), and (1, -4).

The shortest path between two places is what is referred to as a line. The equation for the line is typically written as y = mx + c, where c stands for intercept and m, for slope.

Three lines are to be plotted on the curve that passes through (-3, -5), (-4, 3), and (1, -4) in this case. At any point on the y-axis, any of the three lines should intersect.

In other words, the y=5/3x equation runs between (-3, -5) and 0 on the y-axis.

On the y axis, y = -3/4x goes between (-4, 3) and 0.

On the y axis, y = -4x goes between (1, -4) and 0.

As a result, the necessary equations for the lines are y = 5/3x, y = -3/4x, and y = -4x, respectively, which pass through the y axis and the locations (-3, -5) (-4, 3), and (1, -4)

The sixth term of the geometric sequence is 2048.

The given geometric sequence is 2, 8, 32, 128. We can observe that each term is obtained by multiplying the previous term by 4. Therefore, the common ratio (r) of the sequence is 4.

The formula for the nth term (an) of a geometric sequence is given by:

an = a1 * r^(n-1)

where a1 is the first term and r is the common ratio.

For this sequence, a1 = 2 and r = 4. Plugging in these values into the formula, we get:

an = 2 * 4^(n-1)

To find a6, we substitute n = 6 into the formula:

a6 = 2 * 4^(6-1)
