f(x) = x2 – 8x – 9 , what is the vertex of this function?

Answer:

12 to the 5th power and is it 248,832

Step-by-step explanation:

Answer:

u-5=-4(v-1)

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

V=-u/4+9/4 THIS ANSWER IS IF YOU ARE LOOKING FOR (V)

u=-4v=9 THIS ANSWER IS IF YOU ARE LOOKING FOR (U)

HOPE THIS HELPS:)!!!!!

STAY SAFE

Is this what your looking for?

First compute the component form of vector u by subtracting its initial values from terminal values. 18-1=17, 6-(-12)=18. So u=(17, 18). Since v points in the opposite direction, and has a magnitude three times that of u, we multuply the u by -3 and get v=(-3*17, -3*18)=(-51, -54).

PI =3.14,

, R = 7inch (d =radius /2 >> 14/2)

H =19 inch

Volume = 3.14 x 49in^2 x 19 inch

Answer:

There is no real solution

Step-by-step explanation:

If you are finding the square root of a number, it cannot be negative. No number can be multiplied by itself to get a negative number. Negative numbers multiplied with themselves make a positive number. Positive numbers are obviously going to stay positive. Therefore there is no square root of -9

Answer:

y=3x−4

Step-by-step explanation:

find the tangent line to f(x)=x2−3x+5 at x=3

First, find the value of the function at the given point: y0=f(3)=5

Second, find the slope of the tangent line, which is the derivative of the function, evaluated at the point:  m=f′(3)

Find the derivative:  f′(x)=2x−3

Next, we evaluate the derivative at the given point to find the slope.

m=f′(3)=3

Finally, the equation of the tangent line is  y−y0=m(x−x0)

Plug the values that we found, we get that  y−(5)=3(x−(3))

So basically: y=3x−4

Answer:

a. 14.19 feet

b.  2504.26 cubic foot.

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

(a) Determine the height of the cone to the nearest tenth of a foot.

(b) Determine the overall volume of the tower to the nearest cubic foot.

Please have a look at the attached photo.  

My answer:

Given the information:

The cylinder has:

The cone has:  an inclination angle of 25 degrees

(a) Determine the height of the cone to the nearest tenth of a foot.

Let h is the height of the cone

The distance from C to A is 6 feet and the measure of the angle CAB is 25 degrees. The triangle ABC is a right triangle.

=> sin(CAB) = [tex]\frac{CA}{h}[/tex]

<=> h = [tex]\frac{CA}{sin25}[/tex]

<=> h = [tex]\frac{6}{sin25}[/tex]

<=> h = 14.19 feet

(b) Determine the overall volume of the tower to the nearest cubic foot.

overall volume = volume of the cone + volume of the cylinder

We have:

= 15*[tex]r^{2}[/tex]*π

= 15*[tex]6^{2}[/tex]*π

= 1696.6 cubic foot.

= 1/3*14.19*[tex]6^{2}[/tex]*π

= 534.76 cubic foot.

=> overall volume =  534.76 + 1696.6 = 2504.26 cubic foot.

Hope it will find you well.

Answer: Masha needs 40 more minutes to complete the path.

Step-by-step explanation:

So if Dina is cycling speed is 10km per hour that means it will take Dina 2 hours to completed the the path.

Here;   [tex]\frac{10km}{1h}[/tex] = [tex]\frac{20km}{x }[/tex]  

           10x = 20

       x= 2  

But since Masha still have 4 more km to go  you will add 20 + 4 =24

[tex]\frac{10}{1}[/tex] = [tex]\frac{24}{x}[/tex]

10x= 24

x= 2.4

Answer:

D.) 400π

Step-by-step explanation:

The formula for the area of a circle is:

A = πr²

Substitute the radius into the equation:

A = πr²

A = π(20²)

Solve:

A = π(20²)

A = 400π

Therefore, the area of the circle is 400π square inches.

Step-by-step explanation:

There is one line of symmetry for each side of the pentagon.

Since only 3 vertical lines can be drawn across a pentagon that will divide it equally, hence there are 3 lines of symmetry in the regular pentagon

A line of symmetry is a line that divides a figure equally.

A pentagon is a shape with 5 sides. According to the question weneed t know the lines of symmetry are in the regular pentagon

Answer:

62.84

Step-by-step explanation:

Volume of both cones is approximately 12.57

formula= pi*r^2*h/3

Volume of the cylinder is approximately 37.7

formula= pi*r^2*h

you add the volumes

12.57+12.57+37.7

Step-by-step explanation:

Answer:

72

Step-by-step explanation:

you do this this then this. did it help?

Volume fomula: V = wlh

V = volume

h = height

w = width

l = length

We are given these values:

V = 882

w = 14

l = 7

Solve for h in the orignal formula:

882 = (14)(7)h

882 = 98h

882/98 = 98h/98

9 = h

Therefore, the answer is [ 9cm ]

Best of Luck!

Answer: i think its 98

Step-by-step explanation:

The 32° 15' 66" is the same as 32.27 degree because 1 degree = 60 minutes = 3600 seconds.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, multiplication by a conversion factor.

We have:

32° 15' 66"

Here 15' represents the minute and 66" represents the seconds.

We know 1 degree = 60 minutes = 3600 seconds

15' in degree = 0.25 degree

66" in degree = 0.01833 degree

= 32 + 0.25 + 0.01833

= 32.268 ≈ 32.27 degree

Thus, the 32° 15' 66" is the same as 32.27 degree because 1 degree = 60 minutes = 3600 seconds.
