Answer 2

Answer:

No a circle is not a function.

Step-by-step explanation:

A function is a mapping from 1 set to another

eg, 1 to 2

What is the value of x?

Answers

Answer:

I have no idea. But I just want to let you know to not put this many points, because people are going to take them without answering the question. And I don't know the answer because there are multiple x's.

Answer:

x = 8

Step-by-step explanation:

Remark

I agree with the other responder. You need only pay 20 points to get our attention. (20 will give us 10).

The length from the intersect point to the circle times the entire length of the secant is equal to any other secant divided up the same way.

Put simpler

Equation

(x + 2)(x + 2 + 2x- 8) = (x + 1)(x + 1 + 2x - 5)

Combine like terms

Solution

(x + 2)(3x - 6) = (x + 1)(3x - 4)                    Remove the brackets on both sides.

3x^2 + 6x - 6x - 12 = 3x^2 + 3x - 4x - 4   Combine the like terms

3x^2 - 12 = 3x^2 - x - 4                             Subtract 3x^2 from both sides

- 12 = - x - 4                                               Add 4 to both sides

-12 +4 = - x

- 8 = - x                                                      Multiply both sides by -1

x = 8

Line d has a slope of 3/2. Line e has a slope of -2/3. Are line d and line e parallel or

Answers

Answer:

We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect

Using the dimensions shown, you could create a rectangular prism. Caculate the surface area for the rectangular prism. A 30m2 b 56m2 c 60m2 d 112m2

Answers

Answer:

550ft²

Step-by-step explanation:

Since we are not given the dimension of the rectangular prism. Let us assume;

Length of the rectangular base L = 10ft

Width of the rectangular base W = 15ft

height of the prism H = 5ft

Total surface area of the prism = 2(LW + WH + LH)

Substitute the given values

Total surface area of the prism = 2{10*15 + 15*5 + 10*5}

Total surface area of the prism = 2(150+75+50)

Total surface area of the prism = 2(275)

Total surface area of the prism = 550ft²

Answers

Answer: 1=60°

Step-by-step explanation:

First, let's take our given angle of 30°

30° is in a right triangle, so the angles must be 90°, 60°, and 30°

Now the angle that is 45° makes angle 1 congruent to angle 60°

Meaning angle 1 is 60°

Answer:

m < 1 = 60

Step-by-step explanation:

Since the transversal is perpendicular to m,

it implies that the triangle formed by the perpendicular transversal, the slant transversal and the line m is a right angle triangle.

We use vertically opposite angles property to bring m<1 in to the right triangle.

We now use the sum of interior angles property to obtain,

m < 1 + 30 + 90 = 180

This implies that,

m  < 1 + 120 + 180

We group like terms to obtain,

m < 1 = 180 - 120

This means that,

m < 1 = 60

We could have also used corresponding angles property, then

m < 1 + 30 = 90

m < 1 = 90 - 30

m < 1 = 60

The difference between the roots of the quadratic equation x^2-14x+q=0 is 6. Find q.

Answers

Answer:

The value of q is 40

Step-by-step explanation:

In the quadratic equation ax² - bx + c = 0, where

a = 1

b is the sum of its two roots

c is the product of its two roots

Assume that the roots of the quadratic equations are x and y

∵ The quadratic equation is x² - 14x + q = 0

∴ a = 1 , b = 14 and c = q

∵ b is the sum of its two roots

∵ Its roots are x and y

∴ x + y = 14 ⇒ (1)

∵ The difference between the roots is 6

∴ x - y = 6 ⇒ (2)

Now we have a system of equation to solve it

Add equations (1) and (2)

∴ 2x = 20

- Divide both sides by 2

∴ x = 10

Substitute the value of x in equation (1) or (2) to find y

∵ 10 + y = 14

- Subtract 10 from both sides

∴ y = 4

∵ c is the product of the two roots

∴ c = 10 × 4 = 40

∵ c = q

∴ q = 40

The value of q is 40

Help will give b if correct

Answers

Answer:

[tex]\frac{63}{15 - c} - \frac{63}{15 + c} = 4[/tex]

Step-by-step explanation:

The systems of equations are

Let us assume the rate of the current be c

Now actual speed against the current is (15 - c)

And, the actual speed with the current is (15 + c)

Here we applied the time formula i.e. distance by speed

Also the upstream time  - downstream time = 4

Now the equations are

[tex]\frac{63}{15 - c} - \frac{63}{15 + c} = 4[/tex]

A square has a perimeter of 76 cm. Each side measures x + 3.
What is the value of x, in centimeters?

Answers

A square has all equal sides, so 76/4 is 19.
19=x+3
Subtract the three from both sides
16=x
Or
X= 16 cm

The value of given x is 16

Given that:

Perimeter of square = 76 cm

Side of square = (x + 3)

Find:

The value of x

Computation:

Perimeter of square = 4[Side]

76 = 4[x + 3]

76 = 4x + 12

4x = 76 - 12

4x = 64

x = 64 / 4

x = 16

The value of x = 16
