Answer:

part A: x= 1 and x= 3/2

part B: minimum at (5/4, f(5/4))

Step-by-step explanation:

part A: factoring

0 = 2x^2 - 5x + 3

= (2x^2 - 2x)(-3x + 3)

= 2x(x - 1) -3(x-1)

= (2x - 3)(x - 1)

x= 1 and x= 3/2

part B: candidates test

find the derivative of the function.

f(x) = 2x^2 - 5x + 3

f'(x) = 4x -5

solve for critical numbers.

0 = 4x - 5

x = 5/4

candidates test by plugging in numbers into the derivative to see if that area is negative or pos.

f has a minimum at x = 5/4 because f' goes from neg to pos there. to find the coordinate for x = 5/4 just plug it into the original function to find f(5/4).

Part C: to draw the graph, I'd just plot the vertex coordinate that you solved for in part B, then I would plot the x intercepts that you solved for in part a, from there just draw a line throu the 3 points. (it should look like a U shape)

===============================================

Explanation:

We're told that

cos(B) = 9/41

Since the cosine ratio involves adjacent/hypotenuse, we can see that the adjacent side is 9 and the hypotenuse is 41. For angle B, the adjacent side is the leg closest to the angle in question. So that would be side AB.

Therefore, AB = 9 and BC = 41 are the adjacent and hypotenuse for reference angle B.

Apply the pythagorean theorem to solve 9^2+x^2 = 41^2, and you should get x = 40. This is the other leg of the triangle. Or you could note how tan(C) = 9/40 to imply that AC = 40 is the adjacent side for reference angle C.

Answer:

609m^2

Step-by-step explanation:

Area of the nonshaded part  = (6*11) + (13*7)

Area of the nonshaded part = 66+ 91

Area of the nonshaded part  = 157m^2

Area of the whole figure = (28*14) + (17*22)

Area of the whole figure  = 392+374

Area of the whole figure  = 766m^2

Required area  = 766 - 157

Required area   = 609m^2

Complete Question

Answer:

169.56 square units

Step-by-step explanation:

Find the volume of the cylinder.

Either enter an exact answer in terms of it or use 3.14 for π

Height = 6 units

Radius = 3 units

The formula for the volume of a cylinder =

πr²h

Hence,

Volume of the cylinder = 3.14 × 3² × 6²

= 169.56 square units

Answer:

r = 9

Step-by-step explanation:

[tex] In\: \odot O, [/tex] QP is tangent at point P and OP is radius.

[tex] \therefore OP\perp QP[/tex]

[tex] \therefore m\angle OPQ = 90\degree [/tex]

So, [tex] \triangle OPQ[/tex] is a right angled triangle. Hence, OQ will be its HYPOTENUSE such that OQ = r + 32

Now, by Pythagoras theorem:

[tex] OQ^2 = OP^2 + PQ^2 [/tex]

[tex] \therefore (r + 32)^2 = r^2 + (40)^2 [/tex]

[tex] \therefore\cancel {r^2} + 64r + 1024 = \cancel {r^2} + 1600 [/tex]

[tex] \therefore 64r = 1600-1024 [/tex]

[tex] \therefore 64r = 576 [/tex]

[tex] \therefore r = \frac{576}{64}[/tex]

[tex] \therefore r = 9[/tex]

Answer:

It will take 5 hours for the bakery to bake 1000 loaves.

Answer:

31

Step-by-step explanation:

The angle formed by two secants intersecting outside a circle is equal to half the difference of the intercepted arcs.

So ∠r = [tex]\frac{101-39}{2} =\frac{62}{2} =31[/tex]

angle r is 31 degrees.

Answer:

14.2

Step-by-step explanation:

11L=99

11 99

L=9

9^2 +11^2=c^2

81+121=c^2

sq root 202

14.212670

14.2=c

The area of a rectangle is 99 sq. units and if the width of the rectangle is 11 units then the length will be equal to 9 units.

The opposing faces of a quadrilateral were equal and identical, and all the angles are equal. Around us, there are numerous rectangle-shaped items. Two factors, length, and breadth define each rectangle shape.

As per the data provided by the question,

Area of the rectangle, a = 99 sq. units

width, w = 11 units

a = l × w

99 = l × 11

l = 99/11

l = 9 units.

Therefore, the length of the side is 9 units.

Answer:

The area of the semi-circle is 35.8 cm².

Step-by-step explanation:

The length of the arc is given by:

[tex] s = r\theta [/tex]   (1)

Where:

s: is the length of the arc of semi-circle = 15 cm

r: is the radius

θ: is the angle in radians    

Since we need to calculate the area of the semi-circle, the angle is:

[tex] \theta = \frac{360}{2} = 180 = \pi [/tex]  

From equation (1) we can find the radius:

[tex] r = \frac{s}{\theta} = \frac{15}{\pi} [/tex]    

Now, the area of the semi-circle is:              

[tex] A = \frac{\pi r^{2}}{2} = \frac{\pi (\frac{15}{\pi})^{2}}{2} = 35.8 cm^{2} [/tex]

Therefore, the area of the semi-circle is 35.8 cm².

Step-by-step explanation:

To find his average, we will find the mean. This means we will add 220+166+181 to get 567. When finding the mean we divide the answer but the total amount of addends. In our case we have 3 so we divide 567 by 3.

567 divided by 3 = 189
