Answer:

Below in bold.

Step-by-step explanation:

Using the quadratic formula :

roots =  [-16 +/-√(16^2 - 4*16*5)] / (2*16)

= -0.5 +/- √(-64) /32

= -0.5 +/- 8i/32

= -0.5 + 0.25i and -0.5 - 0.25i

[tex]\sf\longmapsto 16x^2+16x+5=0[/tex]

[tex]\sf\longmapsto x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

[tex]\sf\longmapsto x=\dfrac{-16\pm\sqrt{16^2-4(16)(5)}}{2(16)}[/tex]

[tex]\sf\longmapsto x=\dfrac{-16\pm√256-320}{32}[/tex]

[tex]\sf\longmapsto x=\dfrac{-16\pm√-64}{32}[/tex]

[tex]\sf\longmapsto x=\dfrac{-16\pm8i}{32}[/tex]

[tex]\sf\longmapsto x=\dfrac{-2\pm i}{4}[/tex]

[tex]\sf\longmapsto x=\dfrac{-1}{2}\pm\dfrac{1}{4}i [/tex]

Answer:

4 8/10

Step-by-step explanation:

4x1+4x1/10+4x1/10=4+4/10+4/10=4 8/10

Adding 4 ones, 4 tenths and 4 tenths gives 4.8

To add 4 ones, 4 tenths and 4 tenths, we can combine the whole numbers and the decimal parts separately.

4 ones = 4 x 1

4 tenths = 4 x 1/10

So, 4 ones + 4 tenths + 4 tenths

= 4 x 1 + 4 x 1/10 + 4 x 1/10

= 4 + 0.4 + 0.4

= 4+ 0.8

= 4.8

Therefore, when you add 4 ones, 4 tenths and 4 tenths, the result is 4.4.

Type of variation

1) Direct variation

Simple equation y=Kx

Y varies directly with x

Practical example-

Radius of the circle lit by a car's

Light decreases (y) as the distance away from the garage decreases (c)

2) Inverse variation

Simple equation y=k/x

Y inversely with c

Example- the brightness of a car's light increase (y) as the distance away from the garage decreases (x)

3) Joint variation

Simple equation y=kxz

Y varies jointly with x and z

Example-The heat lose through a glass window (y) varies jointly with the area of the window (x) and the temperature differences between inside and outside

Step-by-step explanation:

The decimal approximation for cot(235°36') is approximately -0.9503.

To find the decimal approximation for cot(235°36'), we first need to convert the angle to degrees.

The given angle is 235°36'. We can convert this to decimal degrees by adding the fraction of minutes to the degree value. There are 60 minutes in a degree, so we divide 36 by 60 to convert it to a fraction of a degree:

36 / 60 = 0.6 degrees

Now, we can add this fraction to the degree value:

235 + 0.6 = 235.6 degrees

The cotangent function is the reciprocal of the tangent function. To find the cotangent of an angle, we can use the following formula:

cot(x) = 1 / tan(x)

Since we want to find cot(235.6°), we can find tan(235.6°) first and then take the reciprocal.

Using a scientific calculator or software, we can find

tan(235.6°) ≈ -1.0529

Now, we can take the reciprocal to find cot(235.6°):

cot(235.6°) ≈ 1 / (-1.0529) ≈ -0.9503

Therefore, the decimal approximation for cot(235°36') is approximately -0.9503.

Answer:

Step-by-step explanation:

Convert the exponential equation to a logarithmic equation using the logarithm base  

( 5 )  of the left side  ( 25 )  equals the exponent  ( 2 ) .   log 5 ( 25 ) = 2

Use the definition of a logarithm,  

log b ( x ) = y  ⟹  b y = x , to convert from the logarithmic form to the exponential form.

Answer:

136

55

53

70

Step-by-step explanation:

1) here x and 136 are alternate interior angles and they are equal

2) here x and 125 lie on the same straight line

so x  + 125 = 180

x = 55

3) here 53 and x are corresponding angles and they are equal

x = 53

4) for this see picture below

side angle to 110 becomes x because of corresponding angles

and as this x and 110 lie on same line

x + 110 = 180

x = 70

Answer:

A) If a line crosses 2 parallel lines, then each angle it forms with the first line is the same angle on the second line. And when 2 lines crosses, the opposite angles are the same.

B) x is 180° - 125° = 55°

C) x is 53° (If a line crosses 2 parallel lines, then each angle it forms with the first line is the same angle on the second line.)

D) x is 180° - 110° = 70°

Answer:

- 5 ≤ x < 3

Step-by-step explanation:

The lower limit has a solid circle at - 5

This means that x can equal - 5

The upper limit has an open circle at 3

This means that x cannot be equal to 3

The inequality represented by the diagram is then

- 5 ≤ x < 3
