Answer 1

Answer:

No real

solution

Step-by-step explanation:

Firstly, let us check if we would be having a real solution

We start by rewriting the equation

We have this as;

8x^2 -25x + 24 = 0

We proceed to get the discriminant

Mathematically, we have this as;

D = b^2 - 4ac

b is the coefficient of x which is -25

a is the coefficient of x^2 which is 8

c is the last number which is 24

So we have;

D = (-25)^2 - 4(8)(24)

D = 625 - 768 = -143

Since the value of the discriminant is negative, there cannot be real roots

What we have as solution are complex roots

Answers

Answer:

when using elimination you "eliminate one variable by adding the equations", so basically in this equation 2y-2y cancel out when you add the equations together. so, you'll find x first. once you find the value of x, then you plug x into one of the equations to find the ordered pair solution, which happens to be (-1,0) in this solution.

New coordinates:

A = (-2, 1)

B = (0, 1)

C = (2, -3)

D = (0, -3)

Step-by-step explanation:

First, determine the ordered pairs for ABCD.

A = (2, 4)

B = (4, 4)

C = (6, 0)

D = (4, 0)

Horizontal movement will only affect the x coordinates of the ordered pairs. Horizontal movement includes moving to the right and left.

Vertical movement will only affect the y coordinates of the ordered pairs. Vertical movement includes moving up and down.

The question asks us to translate 4 units to the left. Moving left on the graph means we will subtract 4 from the x coordinates. The question also asks us to translate 3 units down. Moving down also means subtraction, but from the y coordinate.

New A = (2 - 4, 4 - 3) = (-2, 1)

New B = (4 - 4, 4 - 3) = (0, 1)

New C = (6 - 4, 0 - 3) = (2, -3)

New D = (4 - 4, 0 - 3) = (0, -3)

The new translation will have A at (-2, 1), B at (0, 1), C at (2, -3), and D at (0, -3).

Lines CD and DE are tangent to circle A shown below: Lines CD and DE are tangent to circle A and intersect at point D. Arc CE measures 112 degrees. Point B lies on circle A. If Arc CE is 112°, what is the measure of ∠CDE? (4 points) Question 5 options: 1) 124° 2) 136° 3) 68° 4) 56°

Answers

Answer:

Option (3)

Step-by-step explanation:

By the theorem, angle between two tangents intersecting each other outside the circle is half of the difference between intercepted arcs.

From the figure attached,

Two tangents CD and DE are intersecting each other at point D outside the circle A.

Two intercepted arcs are minor arc CE and major arc CBE,

Measure of arc CE = 112°

Therefore, measure of major arc CBE = 360° - 112°

                                                               = 248°

m(∠CDE) = [tex]\frac{1}{2}(\text{arcCBE}-\text{arcCE})[/tex]

                 = [tex]\frac{1}{2}(248-112)[/tex]

                 = [tex]\frac{1}{2}\times 136[/tex]

                 = 68°

Option (3) will be the correct option.

Step-by-step explanation:

A game has green and blue pieces. The ratio of

green game pieces to total pieces is 5:12.

Select all the statements that are correct about the game pieces.

A. The ratio of green pieces to blue pieces is 7:5.

B. The ratio of total pieces to blue pieces is 12:7,

C. There must be 7 more blue pieces than green pieces.

D. The ratio of total pieces to green pieces is 12:5.

Ratio of green pieces = 5

Ratio of total pieces = 12

Ratio of blue pieces = Ratio of total pieces - Ratio of green pieces

= 12 - 5

= 7

Ratio of blue pieces = 7

A. The ratio of green pieces to blue pieces is 7:5.

Green pieces : blue pieces = 5 : 7

A is not true

B. The ratio of total pieces to blue pieces is 12:7

Total pieces : blue pieces = 12 : 7

B is true

C. There must be 7 more blue pieces than green pieces.

Blue = 7

Green = 5

There are 2 more blue pieces than green pieces

C is not true

D. The ratio of total pieces to green pieces is 12:5

D is true

Need help asap pleas and thank you .

Answers

Answer:

The answer that is not true when x = -4 is B.

Step-by-step explanation:

Since x = -4, that means all we have to do to eliminate answers is plug -4 in place of x.

A is incorrect because 2 × -4 = -8, which means that answer IS true and we're looking for the one that isn't true.

Same with C, -4 + -4 + -4 added together gives you -12 = -12, therefore isn't the right choice.

Finally D. -4/4 divided equals -1, so that would make it -1 = -1.

B is the only one that doesn't make sense, therefore you have your answer.

The graph of a linear function is shown.

What is the Slope of a Line of a Linear Function?

The slope of a line of a linear function = change in y/change in x.

The value of the slope would be positive if the graph increases upwards from your left to your right.

The value of the slope would be negative if the graph decreases downwards from your left to your right.

Thus, the slope of horizontal lines are always zero while the slope of vertical lines are undefined.

Therefore, the slope of the line as shown in the graph of the linear function in the image below is: negative.

Convert r= 2 / 7sinθ−cosθ to rectangular form.

Answers

The rectangular form of the given equation r= 2 / 7sinθ−cosθ which is in polar form is  7x - y = 2 and the slope-intercept form is y = 7x - 2

How to convert from polar form to rectangular form?

To convert from polar form to rectangular form we simply take the following steps:

x = rsinθy = rcosθ

What is slope-intercept form?

The slope-intercept form is,

y = mx +c

where m is the slope made and c is the intercept both made by the straight line.

In the given question let's first rearrange it,

r × (7sinθ − cosθ) = 2

Multiplying the term (7sinθ−cosθ) with r we get,

7rsinθ - rcosθ = 2

Now we will follow the steps discussed above which is we will put x and y respectively in place of rsinθ and rcosθ.

7x - y = 2

So, the slope-intercept form will be,

y = 7x - 2

Therefore, the rectangular form is 7x - y = 2 and the slope-intercept form is y = 7x - 2.

What is addition of two fractions?

To add fractions there are three simple steps:

Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator.

Step 3: Simplify the fraction (if possible)

Given, after six months, she improved her record by 1/15 of a kilometer. After a year, she further improved her record by 1/12 of a kilometer.

Now, 5/6 + 1/15 + 1/12

LCM of denominators 6, 15 and 12 is 60.

50/60 + 4/60 + 5/60

= 59/60

Therefore, Emma's best record is 59/60 kilometers per minute.

1. A signal tower has two lights that are 30 feet apart from each other, one directly above the other. From

a boat, the angle of elevation of the lower light is 14 degrees, and the angle of elevation yo the upper

light is measured to be 32 degrees.

a) Find to the nearest foot the distance from the boat to the lower light.

b) The boat and the foot of the tower are in the same horizontal plane. Find to the nearest foot the

distance from the boat to the foot of the tower.

Answers

Solution :

It is given that the distance between the two lights is 30 feet.

The angle of elevation of the upper light from the boat, ∠ ABP = 32 degree

The angle of elevation of the lower light from the boat, ∠ ABQ = 14 degree

∴ ∠ PBQ = ∠ ABP - ∠ ABQ

              = 32 - 14

              = 18 degree

In triangle PAB

∠ PAB = 180 - (90 + 32)

           = 58 degree

Similarly in triangle AQB

∠ AQB = 180 - (90 + 14)

           = 76 degree

Now considering triangle PBQ and applying the sine theorem,

[tex]$\frac{PQ}{\sin 18}=\frac{BQ}{\sin 58}$[/tex]

we know PQ = 30 feet

∴ [tex]$BQ =\frac{\sin 58}{\sin 18} \times 30$[/tex]

        = 82.33 feet

Again taking the right triangle ABQ and applying sine theorem,

[tex]$\frac{BQ}{\sin 90}=\frac{AB}{\sin 76}$[/tex]

[tex]$\frac{82.33}{\sin 90}=\frac{AB}{\sin 76}$[/tex]

∴ [tex]$AB = 82.33 \times \sin 76$[/tex]

         = 79.88 ft

         = 80 feet
