D) 54

Step-by-step explanation:

input f(4) into x

f(x) = x² + 8x + 6

f(4) = (4)² + 8(4) + 6

f(4) = 16 + 32 + 6

f(4) = 54

Answer:

60 minutes

Step-By-Step Explanation:

1. 12/2= 6 (6 minutes per kilometer)

2. 10000/1000= 10 (10000m is 10km)

3. 10*6= 60min

If this helped, please consider picking this answer as the Brainliest Answer. Thank you!

Answer:

60 minutes or 1 hour

Step-by-step explanation:

Time taken to cover the distance of 2 km = 12 minutes

10000m = 10km

Then time taken to cover the distance of 10 km = 5 x 12 = 60 minutes

I have multiplied 12 with 5 because if we multiply 2km with 5 we will get 10km. So, hope you understood my explanation. If not ask me your doubt in comment.

Answer:34

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ 1, 6 ], thus

f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162

f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8

average rate of change =  =  = 34

Step-by-step explanation:

Using the concept of dilation the volume of the dilated cube when dilated by a factor of 5 is 9375 cm³.

Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.

Given

A cube with a volume of 75 cm³ is dilated by a factor of 5.

The edge of the cube before dilation

Edge³ = 75

Edge   = 4.217

The edge after dilation will be

Edge = 5 x 4.217

Edge = 21.08

The volume of the dilate cube will be

Volume = ( Dilated Edge)³

Volume = 9375

The volume of the dilated cube is 9375 cm³.

Answer:

AEC=BED=157°

Step-by-step explanation:

AEC + CEB + BED + x = 360°

since CEB and x are vertical angles, they are equal.

Also, AEC = BED (same reason)

therefore,

2AEC+ 23° + 23° = 360°

2AEC + 46° = 360°

2AEC = 360° - 46°

2AEC = 314°

AEC = 157°

BED also = 157°

Answer:

The length of the wire will be 44.83 feet.

Step-by-step explanation:

From the information given, the wire is attached from the top of a 30 foot telephone pole to a stake in the ground. if the angle formed by the wire and the pole is 48°.

Therefore, the length of the wire will be:

cos 48° = 30/x

x = 30/cos 48°

x = 44.83

The length is 44.83 feet.

Length of the wire is equals to 35√2 feet.

"Angle of elevation is defined as the angle between the horizontal plane and the line drawn through the point of observation."

Formula used

sinθ = (Opposite side) / Hypotenuse

According to the question,

Given,

Length of the pole = 35feet

Angle of elevation = 45°

Length of the wire = Hypotenuse

'l' represents the length of the wire

Substitute the value in the formula we get,

sin 45° = (35 / l )

⇒ (1 / √2) = (35 / l )

⇒l = 35√2 feet

Hence,  length of the wire is equals to 35√2 feet.

Function assigns the value of one set to another. The whole number that best approximates the value of x is 10.

A function assigns the value of each element of one set to the other specific element of another set.

As it is given that the point √x is plotted on the number line. therefore, the value of x is in square root. Now, in order to get a whole number out of this point function, we need the value of x should be such that when it goes through the function the outcome must be a whole number. therefore, let's substitute the value of x in the function,

A.) 100

[tex]\sqrt{x} = \sqrt{100} = 10[/tex]

B.) 102

[tex]\sqrt{x} = \sqrt{102} = 10.099[/tex]

C.) 103

[tex]\sqrt{x} = \sqrt{103} = 10.149[/tex]

D.) 104

[tex]\sqrt{x} = \sqrt{104} = 10.198[/tex]

As we can see, when the value of x is 100, only then the outcome of the point function is a whole number.

Hence, the whole number that best approximates the value of x is 10.

For these kinds of problems, the point-slope formula comes in handy.

The point-slope form (y - y1 = m(x - x1) +b) uses the slope and a point given to find the y-intercept, or in this case, the equation of the line.

First, we plug the known #'s into the equation, then solve.

y - 7 = -7/3( x -0)

y - 7 = -7/3x

   +7        +7

y = -7/3x +7

Therefore, the equation of the line is: y = -7/3x + 7

Using the binomial distribution, it is found that the spinner is expected to have to spin approximately 132 times for a multiple of 5 to be spun 22 times, hence option 4 is correct.

It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

The expected number of trials until q successes is:

[tex]E_f(X) = \frac{q}{p}[/tex]

In this problem:

Then:

[tex]E_f(X) = \frac{q}{p} = \frac{22}{\frac{1}{6}} = 22 \times 6 = 132[/tex]
