What is the product of 5x4

Answer: draw line segment AB

Step-by-step explanation (A PEX)

The second step in constructing this equilateral triangle is draw two circles with radius AB. Option A is correct.

An equilateral triangle is the triangle in which all the three sides are of equal length in measure.

The first step in constructing this equilateral triangle, to draw segment AB. The second step for this has to find out.

Here, the triangle ABC is shown in the given image. As it is known that all the sides of a equilateral triangle are equal. Therefore,

[tex]AB=BC=AC[/tex]

The first circle is co-occur, the second circle completely. This happens when the two circles made with same radius.

Now from the center point of the circle to the boundary of that circle, is called the radius of the circle., Thus, the line segment AB is the radius of the two circles.

Hence, the second step in constructing this equilateral triangle is draw two circles with radius AB. Option A is correct.

Answer:

The correct option is B.

Step-by-step explanation:

Solution:

The shortest on map is 7cm  

The longest on map is 14 cm  

The shortest in real life is 120 km  

Let the longest in real life is x km  

So,

The ratio is:

7/120 = 14/x  

x = 120*(14) / 7

x=1,680/7

x= 240 km

The longest in real-life is 240 km

Thus the correct option is B....

Remember to follow PEMDAS. PEMDAS = Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction.

Note the equation:

y = (1/4)x + 1

Plug in a number to x, & solve to get the answer for the variable (y).

In this question, they give you 3 numbers to plug into x: 4, 8, 12. Plug them in:

When x = 4

y = (1/4)(4) + 1

Solve. Simplify. Remember to follow PEMDAS. First, multiply 1/4 with 4:

y = (1/4)(4) + 1

y = (1 * 4)/4 + 1

y = 4/4 + 1

y = 1 + 1

Simplify. Combine the terms:

y = 1 + 1

y = 2

when x = 4, y = 2.

When x = 8

y = (1/4)(8) + 1

Solve. Simplify. Remember to follow PEMDAS. First, multiply 1/4 with 8:

y = (1/4)(8) + 1

y = (1 * 8)/4 + 1

y = 8/4 + 1

y = 2 + 1

y = 3

when x = 8, y = 3.

When x = 12

y = (1/4)(12) + 1

Solve. Simplify. Remember to follow PEMDAS. First, multiply 1/4 with 12:

y = (1/4)(12) + 1

y = (1 * 12)/4 + 1

y = 12/4 + 1

y = 3 + 1

y = 4

when x = 12, y = 4.

Answer:

that graph will feature an area delimited by a line of slope m passing through the origin (0,0).

Since m>0 the slope is positive, meaning the line goes up.

Since the equation is y > mx, the inequality sign being >, that means the area represented will be ABOVE the line drawn.  

So it will for sure include ALL quadrant II (with -x and +y values) and NONE of the quadrant IV (with +x and -y values) since the line is passing through the origin (0,0).

Answer:

The graph of y > mx, where m > 0, consists of a dashed line and a shaded half plane. The line has a positive slope and passes through the origin. The shaded half plane is above the line.

The ten-thousandths place is the fifth digit to the left of the decimal point, which is a 7 in this case.

The next number to the right of the 7 is a 4, which is 4 or less, so you don't need to round up the 7.  This means we can just replace the 4 and everything to the right of it with 0s.

If the 4 were 5 or more instead, you would turn the 7 into an 8 and then turn everything after it into 0s.

Answer:

Sara is 4 ft tall

Step-by-step explanation:

Let

x ----> the height of Sarah

using proportion

[tex]\frac{50}{75}=\frac{x}{6} \\ \\x=6*50/75\\ \\x= 4\ ft[/tex]

Final answer:

Using the properties of similar triangles, the height of Sarah is found to be 4 feet tall, given the proportions between the building's height and shadow and Sarah's shadow.

Explanation:

The question requires us to use the properties of similar triangles to find the height of Sarah given that a building 50ft high casts a 75ft shadow and Sarah casts a 6ft shadow. Since the triangles are similar, their sides are in proportion.

To find Sarah's height, we can set up a proportion using the corresponding sides of the similar triangles:

Building's height / Building's shadow = Sarah's height / Sarah's shadow

50ft / 75ft = Sarah's height / 6ft

To solve for Sarah's height, we can cross-multiply and divide:

(50ft × 6ft) / 75ft = Sarah's height

300ft² / 75ft = 4ft

Therefore, Sarah is 4 feet tall.

The missing length on the right triangle is 10 in.

"It is a triangle whose one of the angle measures 90°"

"It is the longest side of the right triangle."

"For a right triangle,

First of all, let's plot all the points, so we get the first figure below. Since a Polygon is a shape with straight sides and closed, then if we draw lines in order for the shape to be closed, we get the shape as shown in the second figure. This polygon is a trapezoid because at least one pair of opposite sides are parallel. To get the area, we know the formula:

[tex]For \ any \ trapezoid: \\ \\ A=\frac{(b_{1}+b_{2})h}{2} \\ \\ b_{1} \ and \ b_{2} \ are \ the \ two \ parallel \ bases \\ \\ h \ is \ the \ height[/tex]

Answer:

4777.28 N

Step-by-step explanation:

The gravitational force down the slope is given by the formula;

(mass *g * sin θ )  

where;

θ is the angle of inclination of the slope

g is the gravitational pull

We plug in the given values into the above expression;

(4,000 x 9.8 x sin 7) = 4777.28 N.  

The frictional force must equal to 4777.28 N (pointing up the slope).

Final answer:

To calculate the friction force acting on a 4000 kg truck parked on a slope, the component of the truck's weight acting down the slope is determined and found to be approximately 4780 N. This value represents the maximum static friction force available to prevent the truck from sliding.

Explanation:

The question is asking to calculate the friction force acting on a truck parked on a slope. To find the friction force, first, we need to calculate the component of the truck's weight that is acting down the slope. This can be found with the formula Wparallel = mg sin(θ), where m is the mass of the truck, g is the acceleration due to gravity (9.8 m/s²), and θ is the angle of the slope.

The truck's weight component acting along the slope is:
Wparallel = 4000 kg * 9.8 m/s² * sin(7°) ≈ 4000 kg * 9.8 m/s² * 0.12187 ≈ 4780 N

The friction force will counteract this downhill force to prevent the truck from sliding. Assuming that the friction force equals the downhill component of the truck's weight to keep the truck stationary, the friction force on the truck is approximately 4780 N. However, without the coefficient of friction, this represents the maximum static friction force that could occur before the truck would start to slide down the slope.

15x - 21x² + 12

Step-by-step explanation:

(3x - 6)(2 X 2 - 7x + 1) = (3x - 6)(4 - 7x + 1)

                                  = (3x - 6)(5 - 7x)

                                  = (3x X 5) + (3x X -7x) + (-6 X 5) + (-6 X -7)

                                  = 15x - 21x² - 30 + 42

Answer:

(3x-6)(2x² -7x+1)

= 6x³ - 33x² + 45x - 6

Step-by-step explanation:

(3x-6)(2x² -7x+1)

To find the product of this we will expand the equation by multiplying each element in one bracket with the other bracket.

(3x-6)(2x² -7x+1)

Expand

(3x)(2x² - 7x + 1) (-6)(2x² - 7x + 1)

Opening the bracket (multiple)

6x³ - 21x² + 3x - 12x² + 42x - 6

Collect like terms

= 6x³ - 21x² - 12x² + 3x + 42x - 6

Answer:

Domain: {0, 1, 2, ..., 175}.

Step-by-step explanation:

We are given that a club bought 175 frisbees at a cost of $200 which you plan to sell for $5 each.

We are to find the domain of this function.

Domain is actually the input into a function which is the x value.

Here sales = 5x where x represents the number of frisbees sold.

So the profit will be:

Profit = Sales - Cost = 5x - 200

Here in this case, the domain would be the number of frisbees sold which is between 0 to 175.

9 is the second number in this sequence

Step-by-step explanation:

So if n is the first integer in this sequence, then the following are true of the sequence of consecutive odd numbers (just means the odd integer right after):

First integer:  n

Second integer: n+2

Third integer: n+4

Fourth integer: n+6

-------------------------------

Sum of these integers are 4n+12=40

Subtract 12 on both sides: 4n     =28

Divide both sides by 4:        n       =7

So first integer 7

Second integer: 9

Third integer:  11

Fourth integer: 13
