Answer:

b  =  16

Step-by-step explanation:

16*x  + b*x  + 4  =  0

Solving for x we get:

x₁,₂  =   - b  ±  √  b² - 4*a*c   ] / 2*a         (1)

If we take a look to the square root

√ b² - 4*4*16      =  √ b²  - 256

if we make √ b²  - 256    = 0

b²  =  256       ⇒      b  =  16

Then equation (1) becomes:

x₁,₂  = ( - 16  ±  0  ) / 32

x  = -  1/2

Answer:

You will use 2 cups of blue paint for 4 cups of yellow paint.

Step-by-step explanation:

Given that:

There is 1/3 cup of blue paint for every 2/3 cup of yellow paint

We will find unit rate in terms of yellow paint.

2/3 cups of yellow paint = 1/3 cup of blue paint

Multiplying both sides by 3/2

[tex]\frac{2}{3}*\frac{3}{2}=\frac{1}{3}*\frac{3}{2}\\1\ cup\ of\ yellow\ paint = \frac{1}{2}\ cup\ of\ blue\ paint[/tex]

Now,

4 cups of yellow paint = [tex]4*\frac{1}{2}[/tex] cups of blue paint

4 cups of yellow paint = 2 cups of blue paint

Hence,

You will use 2 cups of blue paint for 4 cups of yellow paint.

Arithmetic sequence

Step-by-step explanation:

Arithmetic sequences have a common difference d=n2-n1 whilst Geometric sequences have a common ratio r=r2/r1

Clearly, 27-18=9,6-27=9,54-45=9

since there's a common difference,it's an arithmetic sequence

Answer:

Step-by-step explanation:

given: 6 yds / sec

find the time to ride 12 miles,  so how many yards is 12 miles?

12 miles *   1760 yards / 1 mile = 21120 yds

d =r*t    d=distance , r= rate , t = time

we know the distance and the rate .. so we can find the time

d/r = t

21120/6 = t  ( in seconds)

3520 = t sec.

3520 sec *   1 min / 60 seconds   ( to convert to minutes )

3520/60=t ( in minutes)

58 & 2/3  minutes  

Step-by-step explanation:

AB=OB-OA

AB=[4,-2]-[-4,6]

AB=[8,-8],|AB|=8units

BC=OC-OB

BC=[-6,-4]-[4,-2]

BC=[-10,-2],|BC|=√104

AC=OC-OA

AC=[-6,-4]-[-4,6]

AC=[-2,-10],|AC|=√104

d. Based on the lengths of the sides,the triangle is isosceles

Given:

The sum of third and seventh terms of an AP is 20.

To find:

The sum of the first nine ​ terms.

Solution:

We have, the sum of third and seventh terms of an AP is 20.

[tex]a_3+a_7=20[/tex]        ...(i)

nth term of an AP is

[tex]a_n=a+(n-1)d[/tex]

where, a is first term and d is common difference.

[tex]a_3=a+(3-1)d[/tex]

[tex]a_3=a+2d[/tex]       ...(ii)

[tex]a_7=a+(7-1)d[/tex]

[tex]a_7=a+6d[/tex]       ...(iii)

Using (i), (ii) and (iii), we get

[tex](a+2d)+(a+6d)=20[/tex]

[tex]2a+8d=20[/tex]         ...(iv)

Now, the sum of first n terms of an AP is

[tex]S_n=\dfrac{n}{2}[2a+(n-1)d][/tex]

Put n=9 to find the sum of first 9 terms of an AP.

[tex]S_n=\dfrac{9}{2}[2a+(9-1)d][/tex]

[tex]S_n=\dfrac{9}{2}[2a+8d][/tex]

[tex]S_n=\dfrac{9}{2}[20][/tex]           [Using (iv)]

[tex]S_n=\dfrac{180}{2}[/tex]

[tex]S_n=90[/tex]

Therefore, the sum of the first 9 terms is 90.

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

Work Shown:

A = old value = 400

B = new value = 300

C = percent change

C = [(B-A)/A]*100%

C = [(300-400)/400]*100%

C = (-100/400)*100%

C = (-0.25)*100%

C = -25%

The negative value of C means we have a percent decrease. Specifically we have a 25% decrease.

---------

We can see that by saying:

25% of 400 = 0.25*400 = 100

400 - (25% of 400) = 400 - 100 = 300

Answer:

[tex]15000 \times {0.92}^{x} = y[/tex]

x is the number of years and y is the value at x years

The exponential decay model to represent the real-life problem should be considered as the [tex]15000 \times 0.92^{x} = y[/tex].

Since the purchase value of the truck is $15,000

The depreciation rate is 8%

So here exponential decay model should be like

[tex]15000 \times 0.92^{x} = y[/tex]

Hence, The exponential decay model to represent the real-life problem should be considered as the [tex]15000 \times 0.92^{x} = y[/tex].

Answer:

If hanging Christmas lights around the garage door is on your holiday to do list, make sure to do it right. Decorating shouldn't be a once-a-year activity that does permanent damage to your home or your body.

When it comes to hanging holiday lights around your garage door, use clips and hooks specifically designed for the task. Avoid using metal fasteners like staples or nails if you are attaching lights directly to the trim; the metal can damage the wiring and create a fire or electrocution hazard. Instead, clip the plastic fasteners to the light string and attach the plastic fasteners to your trim. This way the clips can remain throughout the year, and lights are more easy to hang in the holidays to come.

For the vertical runs, find the trim clips that wrap around the light string and hold it into place (this is particularly important for our Sioux City and Yankton breezes and blizzards). Aim for a clip every 12 inches or so. Some homeowners choose to nail the clips for stability; others use a removable adhesive.

If you are continuing to light up your house with lights around your roof and gutter lines, there are other items that can help make this process easier. Roof and gutter clips can be pressed directly onto the home's exterior; they typically have a hook at the bottom that grabs the light string. Please be very careful when working on high and precarious locations!
