If the scale of a map is 1 cm : 2500m . The distance between two places in real field is 15 km . What is the distance between the places in map?

Answers

Answer 1

Answer:

To find out actual distance on earth, we need to measure scale. The scale is 1cm to 15 km. Thus, 10 cm on map is equal to ( 10*15) = 150 km on earth. Thus, actual distance on earth is 150 km.

One number is 6 more than twice the other number. If the sum of the two numbers is ​21, find the two numbers

Answers

Answer:

One number, let's call it x, is 6 more than twice the other number, let's say this number is y.

x= 2y+6

x+y=21

We're left with a system of equations.

If we substitute the first equation in the second we find the value of y.

(2y+6)+y=21

3y+6=21

3y=15

y=5

Now that we have found the value of y, we can take that value and substitute it in the second equation (since it's easier) to find the value of x.

x+ (5)=21

x=16

Now to check if our answers are correct, we plug in both values into any equation and see if they equate.

x+y=21

(16)+(5)=21

21=21

A. 15. 7 m2
B. 31.4 m2
C. 78.5 m2
D. 157 m2

Answers

Detailed Answers:

1) B) 18 cm

Radius (r) = 9 cm
Diameter (d) = 2r = 9 * 2 = 18 cm

2) B) A = πr^2

3) A) 50.24 cm^2

Diameter (d) = 8 cm
Radius (r) = d/2 = 8/2 = 4 cm

Area (A) = πr^2

Therefore,
= πr^2
= 3.14 * 4 * 4
= 3.14 * 16
=> 50.24

Area (A) = 50.24 cm^2

4) B) 3.39 m

Area (A) = πr^2 = 36 m^2

Therefore,
πr^2 = 36
3.14 * (r^2) = 36
r^2 = 36/3.14
r^2 = 3600/314
r^2 = 11.46
r = √11.46
=> r = 3.39

Radius (r) = 3.39 m

5) C) 78.5 m^2

Radius (r) = 5 m

Area (A) = πr^2

Therefore,
= πr^2
= 3.14 * 5 * 5
= 3.14 * 25
=> 78.5

Area (A) = 78.5 m^2

Which quadratic inequality does the graph below represent?

Answers

The quadratic inequality represented by the graph is:

y ≤ 2x² - 8x + 3

Which quadratic inequality does the graph below represent?

First, we can see that the shaded region is below the parabola, and the line of the parabola is solid, which means that the points on the parabola are solutions, then the inequality is:

y ≤ quadratic equation.

Now we need to get the quadratic equation.

Now, if you look at the y-intercept, you can see that it happens at y = 3. Then the constant term of the quadratic equation is 3.

Find the x-intercept(s) and the coordinates of the vertex for the parabola y= x^2 -8x + 12. if there is more than one x-intercept, separate them with commas.

Answers

Answer:

(i) x-intercepts: (2, 0), (6, 0)

(ii) vertex : (4, -4)

Explanation:

y = x² - 8x + 12

To find x intercepts, [set y = 0]

x² - 8x + 12 = 0x² - 2x - 6x + 12 = 0x(x - 2) - 6(x - 2) = 0(x - 6)(x - 2) = 0x = 6, x = 2

x-intercepts: (2, 0), (6, 0)

To find vertex:

x = -b/2a

  = -(-8)/2(1)

  = 4

y = x² - 8x + 12

  = 4² - 8(4) + 12

  = -4

Vertex : (4, -4)

Solve the equation for y=0

x²-8x+12=0x²-6x-2x+12=0x(x-6)-2(x-6)=0(x-2)(x-6)=0x=2,6

2(3b³ - 2b² - 5) = 5(b³ - 2) ← distribute parenthesis on both sides

Answers

Subtraction is a mathematical operation that reflects the removal of things from a collection. Supplier B would cost $625 more than supplier A. Thus, the correct option is A.

What is subtraction?

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

The cost of 500 bushels from supplier A will be,

Cost = ($5.25 × 500) + ($3 × 500)

        = $4,125

The cost 500 bushes from supplier B will be,

Cost = $1,500 + ($6.250×500)

        = $4,750

Now, the difference between the two suppliers' costs for 500 bushels will be,

Difference = $4,625 - $4,125 = $500

Hence, Supplier B would cost $625 more than supplier A. Thus, the correct option is A.

[tex]x < -2 \text{ or } x \ge 4[/tex]

==========================================

Reason:

The portion on the left represents [tex]x < -2[/tex] because of the open circle at -2 and shading pointing to the left. This represents all numbers smaller than -2.

The portion on the right represents all values that are 4 or larger; hence [tex]x \ge 4[/tex]. Note the use of a closed circle at 4 to include this value.

We connect those two inequalities with the keyword "or" because x can only pick one of those options, but not both at the same time.

A line traveling to the right with an open dot on x=1.
A line traveling to the right with an closed dot on x=1.
A line traveling to the left with an open dot on x=1.

Answers

Answer:

A line traveling to the left with an open dot on x=1.

Explanation:

The inequality x < 1 basically means "less than 1." On number lines, the further left you go, the smaller the number becomes, and the further right you go, the larger the number becomes. So we know that because it's less or smaller than 1, then the line will be to the left. On the other hand, the inequality does not have a line under it to indicate a "less than or equal to 1," just "less than." Therefore, the dot is open. If there were a line under the inequality, then it would indicate "less than or equal to 1" and the dot would be closed.

Answers

y = x⁴- 5x² + 4 represents the first graph.

y = x(x + 3)(x - 2) represents the second graph.

How to Interpret the graph of a Polynomial?

1) The first polynomial is;

y = x⁴- 5x² + 4

Simplifying this gives us;

y = x⁴- 4x² - x² + 4

y = x²(x² - 4) - 1(x²- 4)

y = (x² - 1)(x² - 4)

y = (x - 1)(x + 1)(x - 2)(x + 2)

Thus, the zeros of this polynomial are; x = -2, -1, 1, 2

From the given graphs attached, first graph has the zeros (x-intercepts) as x = -2, -1, 1, 2.

So graph (1) represents the polynomial  y = x⁴- 5x² + 4

2). The second graph shows the x-intercepts at x = -3, 0, 2

Since, y = x(x + 3)(x - 2) is the polynomial with x-intercepts at x = -3, 0, 2

Therefore, y = x(x + 3)(x - 2) represents the second graph.

On a coordinate plane, circle Q is centered at the origin with radius r. Triangle P Q S is shown. Point Q is at (0, 0) and points P is at (x, y). The length of Q P is r, the length of P S is y, and the length of Q S is x. Angle P S Q is a right angle.If the center of the circle were moved from the origin to the point (h, k) and point P at (x, y) remains on the edge of the circle, which could represent the equation of the new circle?(h + x)2 + (k + y)2 = r2(x h)2 + (y k)2 = r2(k + x)2 + (h + y)2 = r2(x k)2 + (y h)2 = r2 7-foot radius.
