The second graph represents that the function has two complex roots.

What are Complex Numbers?

Complex numbers are made up of two parts: a real number and an imaginary number. Complex numbers serve as the foundation for more complex arithmetic, such as algebra.

Solution:

Since, the graph in the second option is not making any contact with thew point on x-axis it can be very well said that the solutions/roots/zeros of the quadratic equation are complex numbers.

Which is not the case for option one and option two because, the curves are making intercepts on x-axis thus, giving real roots.

Answer:

I'm doing the same exact test, it's B.

The value of s in the point (s,-3) after using slope formula is -4.

What is slope?

Slope is a term used to define how steep a line is. The rise of a line over the run of a line, or the change in the vertical direction (y) over the change in the horizontal direction, is the definition of slope (x). The slope is the angle at which one is moving forward or backward when skiing down a hill or climbing a mountain. Depending on what it is, the slope may occasionally be fairly flat or extremely steep. The slope of an object indicates how steep it is. Slope knowledge is crucial for daily decision-making. 

Using slope formula,

=> slope m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Now the given point  is ,

[tex](x_1,y_1)=(s,-3) \\(x_2,y_2)=(-8,-4)[/tex]

=> slope m= 1/4

=> [tex]\frac{1}{4}= \frac{-4+3}{-8-s}[/tex]

=> [tex]\frac{1}{4} = \frac{-1}{-8-s}[/tex]

=> -8-s=-4

=>-s=-4+8

=> -s=4

=> s =-4.

Hence the value of s is -4.

The value of x is 18.8m

Given:

θ = 48°

Y = 17m

The law of tangent which is also called as tangent formula or tangent rule is the ratio of the sine of the angle to the cos of the angle.

tan θ = Opposite / Adjacent.

Here,

Sum of triangle = 180°

90° + 48° + x° = 180°

x° = 42°

tan θ = opposite/ adjacent.

Substituting the values

tan 42° = 17/x  (∴tan 42° = 0.9004)

0.9004 = 17/x

1) The yearly depreciation expense under the straight-line method is $2,000.

2) If the car was bought on April 3, the depreciation expense for the first year is approximately $1,500.

Under the straight-line depreciation method, the depreciation expense is the quotient of the depreciable amount (cost - residual value) divided by the estimated useful life of the asset.

The depreciation expense is prorated if it does not cover the full year.

Cost of car = $12,000

Estimated useful life = 5 years

Residual value = $2,000

Depreciable amount = $10,000 ($12,000 - $2,000)

Straight-line Depreciation (annual) = $2,000 ($10,000/5)

Depreciation for first year (April 3) = $1,496 ($2,000 x 273/365)

≈ $1,500

Thus, using the straight-line method, the depreciation expense for the car in each year is $2,000.

The area of the triangle is 8 unit².

The amount of space a shape takes up is called the area of that space.

Here,

The given vertices are

A= (-4,1)

B= (-7,5)

C= (0,1)

Now, as we know the x and y coordinates of three vertices of triangle.

So, we will use the coordinate geometry formula.

The general formula of the area of triangle is

If the triangle have a vertices (Ax,Ay ),(Bx,By ) and (Cx,Cy ) then the area is

Area=1/2×|Ax (By-Cy )+Bx (Cy-Ay )+Cx (Ay-By )|

Now, we will put the given coordinates values in above equation

Then we will get

Area=(1/2)×|(-4)(5-1)+(-7)(1-1)+0(1-5)|

Area=(1/2)×|(-4)(4)+(-7)(0)+0(-4)|

Area=(1/2)×|-16|

Remove the mode bracket.

Area=1/2×16

Area=8

Thus, the area of the triangle is 8 unit².

Answer:

Determine whether the equation is half or double the given number, then solve for x.

Step-by-step explanation:

The hash marks on the sides of the triangles tell you that the pieces of the triangles are the same length. The piece with one mark is the same length as the other piece with one mark. The piece with two marks is the same length as the other piece with two marks.

This is important because it tells you that the place where the triangle is divided is at its halfway point — so, the triangles are cut right in half. The line that cuts the triangle in half will always be half the length of the line that is the bottom of the triangle. You can use this to solve for x in each of these problems.

12) We are trying to solve for x along the length of the longer line. The halfway-point line is seven.

Seven is half of fourteen (7*2=14). So, the longer line is 14.

Since the longer line has the equation 2x, we must determine what times two is fourteen. To find that, we would divide fourteen by two (division and multiplication are inverse operations). 14/2=7.

x=7.

15) We are trying to solve for x along the length of the shorter line. The longer line is 35.

The shorter line is half of the longer line, so in this case it is half of 35, which is 17.5.

However, in the equation, we subtract 8 from x. So, we have to find the number that becomes 17.5 only after you subtract 8. To do this, you simply add 8 to 17.5 (addition and subtraction are inverse operations). 25.5 - 8 = 17.5.

x = 25.5.

The families of solutions (variable x) for the square root of the trigonometric expression 2 · cos x - 1  equal to 0 are x₁ = π / 6 + i · 2π and x₂ = 11π / 6 + i · 2π, where i is an integer.

In this question we find the following trigonometric expression:

√(2 · cos x - 1) = 0

Where x is measured in radians.

By algebra properties and trigonometric formulas we must solve the trigonometric expression for x. First, use algebra properties until the trigonometric function is cleared:

√(2 · cos x - 1) = 0

2 · cos x - 1 = 0

2 · cos x = 1

cos x = 1 / 2

Second, find the family of solutions for the square root of the trigonometric function:

x₁ = π / 6 + i · 2π, where i is an integer.

x₂ = 11π / 6 + i · 2π, where i is an integer.

How do you determine a line's slope?

The slope is calculated by dividing the difference between the y-coordinates of two points on a line by the difference between their x-coordinates.

Step-by-step explanation:

Given that credit x = 32.86
and time for calling y = 22
slope is m = -0.13
c = ?

Equation of line
y = mx + c
32.86 = -0.13(22) + c

32.86 + 2.86 = c

c = 35.72
now we have c we can calculate credit at time 35 min
y = -0.13(35) + 35.72

You want to know the value of 1010 in binary.

We're not sure if you have the base ten number 1010 and you want its value in binary, or if the number 1010 is in binary, and you want its value in base ten.

Converting the base ten number to binary means looking at the remainders from division by 2, until the quotient is zero.

The binary value is the list of these remainders from the bottom up:

  1010₁₀ = 11 1111 0010₂

(It is often convenient for readability to group the digits by 3 or 4.)

The conversion from binary essentially uses the expanded form of the number. The arithmetic is done in the base you're converting to. Here, that's base ten.

  1010₂ = 1×2³ +0×2² +1×2¹ +0×2⁰ = 8 +2 = 10

  1010₂ = 10₁₀

The correct ascending order is 33000 cm, 0.34 km, 430 m.

to find the ascending order we firstly have to convert the  all values into a same unit system.

we will convert all the values into cm units.

so, 0.34 km = 0.34*100000 cm,

0.34 km = 34000 cm.

similarly 430 m = 430* 100 cm,

430 m = 43000 cm.

and lastly we have 33000 cm.

so in all the values 33000 cm is smallest and 43000 cm is largest and the correct ascending order will be 33000 cm, 0.34 km, 430 m.
