Answers

Answer 1

Answer: the diameter of the circle is about 19.8

Step-by-step explanation:

Since the length of the square is 14 units, we can use the Pythagorean theorem to find the diagonal:

14^2 + 14^2 = c^2

196 + 196 =c^2

392 = c^2

c = about 19.8

Answer 2

Answer:

19.8

Step-by-step explanation:

The diameter of the base of the cylinder is equal to the diagonal of the inscribed square and is equal to the hypotenuse of an equilateral triangle into which the square is divided by diagonals ... By the Pythagorean theorem, the diameter (hypotenuse) is equal to the square root of the sum of the squares of the legs and is equal to 19.8

How to solve -7=5x-2. 2 step equations using inverse operations

Answers

Answer:

-1

Step-by-step explanation:

Add 2 to both sides of the equation: -7 + 2 = 5x - 2 + 2. This gives you -5 = 5x.

Divide both sides of the equation by 5: -5/5 = 5x/5. This gives you -1 = x.

So the solution to the equation is x = -1.

Alternatively, you can also use inverse operations to solve the equation by isolating x to one side.

Add 2 to both sides of the equation: -7 + 2 = 5x - 2 + 2. This gives you -5 = 5x

Divide both sides of the equation by 5: -5/5 = 5x/5. This gives you -1 = x

So the solution to the equation is x = -1.

-7=5(-1)-2
-7=-5-2
-7=-7

Given the system of equations: 5x + 2y = 3 4x − 8y = 12 Solve for (x, y) using elimination.

Answers

To solve the system of equations using elimination, we can follow these steps:

Multiply the first equation by 4, and the second equation by 2:

20x + 8y = 12

8x - 16y = 24

Add the two equations together:

20x + 8y = 12

8x - 16y = 24

28x - 8y = 36

Solve for x by dividing both sides of the equation by 28:

x = 36/28 = 9/7

Substitute the value of x back into one of the original equations:

5x + 2y = 3

5(9/7) + 2y = 3

45/7 + 2y = 3

2y = -42/7

Solve for y by dividing both sides by 2:

y = -21/7

So the solution of the system of equations is (x,y) = (9/7, -21/7)

It is also worth noting that we could have also multiplied the first equation by -2 and the second equation by 5 and added them together, this will also lead us to the same solution.

Complete the following tables with values for the functions f _ and h given that: (a) f is an odd function: (b) g is an even function. (c) h = g(f(x)) h(x)

Answers

The result is that h(x) = 0 for all x except for x = -2 and x = 2, where h(x) = 6.

f(x)   | -2 | -1 | 0 | 1 | 2

g(x)   | 6  | 0  | 0 | 0  | 6

h(x)   | -2 | -1 | 0 | 1 | 2

-------|----|----|----|----|----

h(x)   | 6  | 0  | 0 | 0  | 6

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

For x = -2, h(x) = g(f(-2)) = g(5) = 6

For x = -1, h(x) = g(f(-1)) = g(-3) = 0

For x = 0, h(x) = g(f(0)) = g(0) = 0

For x = 1, h(x) = g(f(1)) = g(-3) = 0

For x = 2, h(x) = g(f(2)) = g(5) = 6

Since f is an odd function and g is an even function, then h(x) = g(f(x)) will be an even function. This means that for any given x, h(x) will always equal 0 or a positive value. For the set of values provided above, the result is that h(x) = 0 for all x except for x = -2 and x = 2, where h(x) = 6.

A ball is thrown straight down from the top of a 220-foot building with an initial velocity of - 22 feet per second. (Use the position function s(t)=−16t2+v0t+s0 for free-falling objects.)
(a) What is its velocity after 3 seconds?
(b) What is its velocity after falling 108 feet?

Answers

The velocity after 3 second is -118 ft/sec and the velocity after falling 108 feet is -87.6 ft/sec.

(a)

For the given position function

[tex]s(t)=-16t^2+v_0.t+s_0[/tex]

The ball is dropped from top of the building of height 220 ft, therefore

[tex]s_0=220ft[/tex]

Also, the initial velocity of the ball is −22 feet per second, thus.

[tex]v_0=22\frac{ft}{s}[/tex]

We will differentiate the position function to find the velocity function and then calculate velocity at (a) t=3sec and (b) after failing 108 ft.

Differentiate Position function to acquire the velocity function v(t).

[tex]s(t)=-16t^2+v_0.t+s_0\\\\s'(t)=-32t+v_0[/tex]

Now substitute t=3s,

v(3) = -32(3) + (-22)

v(3)= -118 ft/sec

b)

To find the velocity of ball after falling 108 ft, first we need to find the time at which ball is dropped 108 ft. and then find velocity at that time using velocity function.

let s(t)=108 ft, then using position function, we can write

[tex]s(t)=-16.t^2+v_0t+s_0\\\\108=-16t^2+(-22)t+220\\\\-16t^2-22t+112=0[/tex]

After solving the quadratic equation, we get

t= -3.42 and 2.05

Since time always positive,

therefore t=2.05 sec.

v (2.05) = -32(2.05)-22

v (2.05) = -87.6 ft/sec

Abdi and Bashir run in an ultra marathon. After 5 hours Abdi is 4 miles behind Bashir If at this point in the race, Abdi begins to run at a constant speed of 8 mph and Bashir runs at a speed of 6 mph. How long will it take for Adbi to catch up with Bashir?

Answers

Using the Time-Distance Formula, it will take Adbi 2 hours.

How to Use Time-Distance Formula to Calculate Time?

We can use the time-distance formula to find how long it will take for Abdi to catch up with Bashir. The time-distance formula is distance = speed x time.

Let t be the time in hours that it takes for Abdi to catch up with Bashir.

We know that the distance Abdi has covered is 4 miles more than Bashir, and the relative speed between the two runners is 8mph - 6mph = 2mph.

So we can write the equation:

4 = (8 - 6) * t

Solving for t, we get t = 4/2 = 2 hours.

So it will take Abdi 2 hours to catch up with Bashir.

On the coordinate plane, the segment B(1-4) toC(7,4) forms, one side of triangle BCD. The triangle has an area of 15 square units select all points where D you could be

Answers

A coordinate plane is a two-dimensional graph that is used to locate points in a plane using an x-axis and a y-axis.

Explain about coordinate plane:Each point on the plane is defined by an x-coordinate (horizontal position) and a y-coordinate (vertical position). It is used in various branches of mathematics and sciences, such as geometry, algebra, and physics. It is a fundamental tool for graphing and analyzing mathematical equations and functions.To find the possible coordinates of point D, we first need to find the equation of the line that passes through points B(1, -4) and C(7, 4). We can use the slope-intercept form (y = mx + b) to find the equation of the line. Each point on the plane can be identified by its x and y coordinates, which are the distances from the point to the y-axis and x-axis, respectively. The x-coordinates are measured to the right of the y-axis, and the y-coordinates are measured upward from the x-axis. The coordinate plane is used to graph equations and inequalities, plot points, and identify patterns in data. It is a fundamental tool for understanding and manipulating mathematical concepts.

The slope of the line is (4-(-4))/(7-1) = 8/6 = 4/3.

The y-intercept is -4.

So the equation of the line is y = (4/3)x - 4.

We know that the area of triangle BCD is 15 square units. To find the possible coordinates of point D, we can use the formula for the area of a triangle (A = (1/2)bh). Since we know the area and the base, we can find the height of the triangle and use that to find the possible coordinates of point D.

The equation of the line is y = (4/3)x - 4. We can use this equation to find the y-coordinate of point D.

y = (4/3)x - 4

15 = (1/2)(x)((4/3)x - 4)

By solving the equation above, we can find the possible x coordinate of point D, which are (-2, -4/3) and (12, 4). Therefore, the possible coordinates of point D are (-2, -4/3) and (12, 4).

Note: you can use the same formula to find the y coordinate if you were given the x coordinate of D, but it gives the same solution.

The quadrilaterals in a and b have the missing values of x as 85° and 57° respectively and can be best described as a scalene quadrilateral.

What is a scalene quadrilateral

A scalene quadrilateral is a four-sided polygon in which all four sides have different lengths and all four angles have different measures. This is also known as an asymmetric quadrilateral.

we shall evaluate for the missing values of x as follows:

x + 109° + 96° + 70° = 360° {sum of interior angles of a quadrilateral}

x + 275° = 360°

x = 360° - 275° {subtract 275° from both sides}

x = 85°

x + 85° + 94° + (180° - 58°) = 360° {sum of interior angles of a quadrilateral}

x + 301 = 360°

x = 360° - 303° {subtract 303° from both sides}

x = 57°

Therefore, the missing values of x for quadrilaterals in a and b are 85° and 57° respectively, and can be best described as a scalene quadrilateral.

Answers

While the new helmets decrease the probability of injury resulting from a scooter accident, but they also incentivize individuals to ride more recklessly, which could increase the number of scooter collisions and therefore injuries to renters.

The reason for the above statement is based on the concept of risk compensation. When the perceived risk of an activity is reduced, individuals may engage in more risky behavior. For example, if individuals believe that wearing a helmet makes them safer while riding a scooter, they may feel less concerned about the potential consequences of riding recklessly, leading to an increase in the number of accidents. On the other hand, the helmet does decrease the probability of injury in the event of a crash, but an increase in the number of crashes could lead to an overall increase in the number of injuries, offsetting the protective effect of the helmets. Therefore, the net impact of the new helmets on the number of scooter injuries is unclear, and further study is needed to determine their overall effect.

Solve the system of equations: 3 � - � = 17 5 � + 3 � = 5

Answers

The solution to the system of equations 3x - y = 17 and 5x + 3y = 5 is (4, -5)

What is an equation?

An equation is an expression showing the relationship between numbers and variables.

Given the equations:

3x - y = 17 ;    multiplying by 3:

9x - 3y = 51     (1)

5x + 3y = 5     (2)

To solve by elimination method, subtract add 2 to equation 1, hence:

14x = 56

Dividing by 14:

x = 4

Put x = 4 in equation 2:

5(4) + 3y = 5

20 + 3y = 5

3y = -15

y = -5

The solution is (4, -5)

When building a house, the number of days required to build is inversely
proportional to with the number of workers. One house was built in 85 days by 5
workers. How many days would it take to build a similar house with 25 workers?

Answers

It would take 17 days to build a similar house with 25 workers.

What is Inverse Proportion?

Inverse proportion is a type of proportionality relationship. If two quantities are inversely proportional then as one quantity increases, the other decreases.  In inverse proportion, the product of the given two quantities is equal to a constant value

One house was built in 85 days by 5 workers;

The relationship will be;

d ∝ 1/n

where

n = number of workers

d = number of days

d = k/n

when d = 5

k = 85

k = 5 x 85

k = 425

when n = 25

d = 425/25

d = 17

The length of a rectangle is seven more than triple the width.if the perimeter is 126 inches, find the dimension

Answers

Length= 7 + 3width
Perimeter= 126
Let width= W
Length = L
Equation form,
2L + 2W = 126
Sub L = 7+3W into eq above
2(7+3W) +2W = 126
14 + 6W + 2W = 126
14 + 8W = 126
8W = 112
W = 14
Then,
Sub W=14 into L=7+3W
L=7+3(14)
L=7+42
L= 49

Answer,
Width=14 inches
Length = 49 inches
