Answer:

x = 140

Step-by-step explanation:

The figure is a quadrilateral. That means it has 4 sides and more importantly for this question 4 angles. All quadrilaterals have 4 angles that add up to 360o.

You know 3 of the angles. The fourth one is x.

90 + 90 + 40 + x = 360                    Combine like terms on the left

220 + x  = 360                                  Subtract 220 from both sides.

220 - 220 + x = 360 - 220               Combine all like terms

4/8 simplifies to 1/2. Multiply 1/2 by 100 to get 50%. Thus, 4/8 expressed as a percent is 50%.

To express 4/8 as a percent without dividing, first, recognize that 4/8 simplifies to 1/2 by dividing both the numerator and denominator by their greatest common divisor, which is 4.

Then, to convert 1/2 to a percent:

1. Multiply 1/2 by 100 to express it as a percentage.

  (1/2) × 100 = 50.

So, 4/8 as a percent without dividing is 50%.

Steps:

1. Simplify 4/8 to 1/2.

2. Multiply 1/2 by 100 to convert to a percent.

  (1/2) × 100 = 50.

Therefore, 4/8 equals 50% without dividing.

Answer:

[tex]y = 2 sin (\frac{2x- 1}{16 \pi} ) - 1[/tex]

Step-by-step explanation:

We know that the standard form of equation for the sine function is given by:

[tex]y = Asin(Bx-C)[/tex] where [tex]A[/tex] is amplitude, period is [tex]\frac{2\pi }{B}[/tex] and the phase shift is equal to [tex]Bx-C[/tex] set to zero. [tex]C[/tex] is then obtained by this equation.

Here in this problem: A is equal to 2, period=2π/B=2π/2=π, where B is equal to 2 and the phase shift is equal to 2x - 1/16 pi = 0.

[tex] y = 2 sin (\frac { 2 x - 1 } { 16 \pi} ) - 1[/tex]

To construct the sine function y = 2 × sin(2(x + π/8)) + 3, you need to consider the given amplitude, period, phase shift, and vertical shift and substitute them into the general sine equation form.

Constructing the Sine Function

To write a sine function with a given amplitude, period, phase shift, and vertical shift, we use the general form of the sine equation:

y = A × sin(B(x - C)) + D

Given the data:

Amplitude (A): 2

Period: π

Phase Shift (C): -1/8 π

Vertical Shift (D): 3

First, determine B using the formula for the period: Period = 2π / B. Since the period is π:

π = 2π / B

Solving for B, we get:

B = 2

Next, substitute A, B, C, and D into the general form:

y = 2 × sin(2(x + 1/8π)) + 3

The phase shift is negative, indicating a shift to the left. Therefore, the equation becomes:

y = 2 × sin(2(x + π/8)) + 3

Now, you have the sine function with the specified characteristics.

To solve the inequality 2x - 4 ≤ 12, add 4 to both sides to get 2x ≤ 16, then divide both sides by 2, resulting in x ≤ 8. This means x can be any number less than or equal to 8.

To solve the inequality 2x − 4 ≤ 12, we first isolate the variable x by following algebraic steps. Here's a step-by-step approach:

The solution to the inequality tells us that x can be any number less than or equal to 8. This is true for any real number x that satisfies the condition outlined by the inequality.

Remember, when solving inequalities, it's crucial to maintain the balance of the equation by performing the same operations on both sides. Also, note that multiplying or dividing both sides of an inequality by a negative number requires flipping the direction of the inequality sign, which was not necessary in this case since we divided by a positive number (2).

A wall that measures [tex]1 \frac{3}{4}[/tex] inches on a blueprint with a scale of 1 / 4 inch equals 1 foot is 7 feet long in actual size after converting the measurements.

The question is about converting a measurement on a blueprint to the actual size in feet. To find out how many feet long a wall that measures [tex]1 \frac{3}{4}[/tex] inches on the blueprint is, we apply the given scale factor. The scale on the blueprint is

1 / 4 inch equals 1 foot. Therefore, to find the actual length in feet, we divide the measured length on the blueprint by the scale factor.

[tex]1 \frac{3}{4}[/tex] inches can be converted to a decimal which is 1.75 inches. Now, we divide 1.75 inches by the scale of 1 / 4 inch per foot:

1.75 inches / (1/4 inches/foot) = 1.75 inches X (4 feet/1 inch) = 7 feet

So, a wall that measures 1.75 inches on the blueprint is 7 feet long in actual size.

The coordinates for the origin of the coordinate plane is (0,0).

A Cartesian coordinate system in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length.

The coordinate plane consists of two axes which are the two mutually perpendicular lines, the X-axis and the Y-axis respectively.

The point of intersection of these two axes is known as the origin of the coordinate plane.

For the frame of reference, we take the origin of the coordinate plane as (0,0).

Therefore, the coordinates for the origin of the coordinate plane is (0,0).

Step-by-step explanation:

y-intercept is for r = 0.

We have the equation y = -3 - 7r.

Substitute r = 0:

y = -3 - 7(0) = -3 - 0 = -3

Other way.

The slope-intercept form of an equation of a line:

y = mx + b (y = mr + b).

m - slope

b - y-intercept

We have the equation y = -3 - 7r = -7r - 3. Therefore m = -7 and b = -3.

Answer:

f(-4) = 10.636

Step-by-step explanation:

In this problem we need to substitute and add together the remaining terms

f(x)=6−2+2e−0.3x

If we simplify

f(x) = (6−2) +2e−0.3x

f(x) = (4) +2e − 0.3x

We substitute the value for e (Euler's number)

e = 2.718

f(x) = (4) +2(2.718) − 0.3x

f(x) = (4) + 5.436 − 0.3x

f(x) = 9.436 -0.3*x

We just need to substitute for x = -4  ,  to get f(-4)

f(-4) = 9.436 -0.3*(-4)

f(-4) = 9.436 + 1.2

f(-4) = 10.636

Answer:

1) (9, 75+360n)

2) (−9, 255+360n)

Step-by-step explanation:

(9, 75) is same as (9, 75 + 360)

so it would be (9, 435)

It can also be expressed as (-9, 75 + 180 degrees)

so (-9,255) degrees

In general, (9,75+360 n) for n≥0 represents half of the possible ways of representing the point : (9,75)  

All the polar coordinates of point p = (9, 75°) are p(2.329, 8.693), p(-2.392, 8.693), p(-2.392, -8.693) and p(2.392, -8.693).

Coordinate is basically point on a surface which shows the position of point on the surface. It is like (x,y) in which x is the point on x axis and y is the point on y axis?

We know that x coordinate is r cosΘ and y=r sin Θ. and we have to first find the x coordinates and y coordinates.

The polar coordinates of point p:

1. p(9cos75, 9sin75) = p(2.329, 8.693)

2. p(9cos(180i - 75), 9sin(180 - 75)) = p(-2.392, 8.693)

3. p(9(cos(180 + 75), 9sin(180 + 75)) = p(-2.392, -8.693)

4. p(9cos(360 - 75), 9sin(360 - 75)) = p(2.392, -8.693)

Hence all the polar coordinates of point p = (9, 75°) are p(2.329, 8.693), p(-2.392, 8.693), p(-2.392, -8.693) and p(2.392, -8.693).
