As;

(8^0.5)² +(3)²=(17^0.5)²

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)

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.

I hope it helps you!                          

For part (a), you don't need to type in the "y=" portion as that is already done for you. For any answer choice involving a percentage, type in the number only. This is because the percent sign is already taken care of.

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

Explanation:

Part (a)

Note how each time x goes up by 1, y drops by 0.2

We can see that

slope = rise/run

slope = (change in y)/(change in x)

slope = (-0.2)/(1)

slope = -0.2

This tells us that the battery life goes down by 20 percentage points for each hour. Note: This is not the same as saying it drops by 20% each time, as this is a subtle difference; however, I can see what your teacher is trying to say for part (b).

The y intercept is b = 1 since this is the location where the graph crosses the y axis.

The slope m = -0.2 and y intercept b = 1 leads y = mx+b to turn into y = -0.2x+1 which is the final answer for part (a).

As a way to check, plug in x = 0 and you should get y = 1. Plug in x = 1 and you should get y = 0.8, and so on. The (x,y) values should match what the graph shows.

----------------------------

Part (b)

As mentioned previously, the slope tells us how much the battery is changing. It's the rate of change. Specifically in this case, the battery is losing 20 percentage points for each hour. Your teacher should have used this careful phrasing, rather than say "the battery life goes down by 20% for each hour" but I can see what they're going for. So 20 is the answer for the first box of part (b)

The x intercept is where the graph crosses the x axis, which is x = 5 in this case. The x intercept always happens when y = 0. When y = 0, the battery is completely dead at 0%. Therefore, we can get 5 hours of battery life. The value 5 goes in the second box of part (b).

On the other end of the spectrum, the battery is 100% full when x = 0, which is at the start of everything. This is due to the y intercept b = 1.0 which represents 100%. In other words, the person starts off with a 100% charge, and they use their laptop for 5 hours, at which point the battery is at 0%. The value 100 goes in the third box for part (b)

----------------------------

Part (c)

We are asked to find the value of x when y = 0.75

y = -0.2x+1

0.75 = -0.2x+1

0.75-1 = -0.2x

-0.25 = -0.2x

-0.2x = -0.25

x = -0.25/(-0.2)

x = 1.25

After 1.25 hours the battery is at 75%

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

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.
