Given:

The term is [tex]5^x[/tex].

To find:

The differentiation of [tex]5^x[/tex] with respect to x.

Solution:

Formula used:

[tex]\dfrac{d}{dx}a^x=a^x\log(a)[/tex]

Let the given function is:

[tex]f(x)=5^x[/tex]

Here, a=5.

Differentiate the given function with respect to x.

[tex]f'(x)=5^x\log(5)[/tex]

Therefore, the derivative of [tex]5^x[/tex] with respect to x is [tex]5^x\log(5)[/tex].

Answer:

  2.  (b) 6 feet by 18 feet

  3.  -5, -1

Step-by-step explanation:

2. Perhaps the easiest way to answer this is to check to see what the areas are of the offered choices:

  a) 7·19 = 133 . . . . numbers are odd, so the answer is odd, incorrect

  b) 6·18 = 108 . . . . correct choice

  c) 12·24 = 288

  d) 5·17 = 85 . . . . again an odd number

__

If you were to solve this by factoring, you would be looking for factors of 108 that have a difference of 12.

  108 = 1·108 = 2·54 = 3·36 = 4·27 = 6·18 = 9·12

The differences are 107, 52, 33, 23, 12, 3. The dimensions you want are 6 and 18 feet.

3. Completing the square is easier if the quadratic has a leading coefficient of 1. Here, all of the coefficients are divisible by 2, so we can simplify this to ...

  x^2 +6x = -5 . . . . . . divide both sides by 2

Now, we complete the square by adding the square of half the linear term coefficient.

  x^2 +6x +9 = 4 . . . . add (6/2)^2 = 9 to both sides

  (x +3)^2 = 4 . . . . .  write as a square

  x +3 = ±2 . . . . . . . take the square root

  x = -3 ±2 = -5, -1 . . . . add -3 to both sides

The solutions are -5 and -1.

Answer:

Step-by-step explanation:

The key here is to find out how long it will take Justin to triple his money, and then use that number of years in Hailey's equation. If Justin starts with $940, he will triple his money when he has $2820 (940*3). We need to find out how long it takes him to do this using the equation

[tex]A(t)=P(1+\frac{r}{n})^{nt}[/tex]where A(t) is the tripled amount of money, P is the initial investment, r is the interest rate in decimal form, n is the number of compoundings done per year, and t is the time in years. Filling in and solving for t:

[tex]2820=940(1+\frac{.07625}{12})^{12t[/tex] which simplifies a bit to

[tex]2820=940(1+.0063541667)^{12t[/tex] and a bit more to

[tex]2820=940(1.0063541667)^{12t[/tex] Begin to solve for t by dividing both sides by 940 to get:

[tex]3=(1.0063541667)^{12t[/tex] and then take the natural log of both sides to get the t alone eventually. Taking the natural log on the right side enables us to move the 12t down in front. So doing all of that at the same time:

[tex]ln3=12tln1.0063541667[/tex] and divide both sides by ln(1.0063541667):

[tex]173.4450855=12t[/tex] then finally divide both sides by 12 to get

t = 14.5 years. Now we use that number of years to find out how much Hailey will have.

[tex]A(t)=940(1+\frac{.0825}{4})^{(4)(14.5)}[/tex] which simplifies a bit to

[tex]A(t)=940(1+.020625)^{58[/tex] and a bit more to

[tex]A(t)=940(1.020625)^{58[/tex] and

A(t) = 940(3.26768151) so in 14.5 years, Hailey will have

A(t) = $3071.62

Answer:

option A

Step-by-step explanation:

∠WPS +∠OPW  = 180   {straight line}

∠WPS +110 = 180

∠WPS = 180 - 110

∠WPS = 70°

∠RWQ + ∠QWT +∠TWU = 180   {straight line}

∠RWQ + 60 + 50 = 180

∠RWQ + 110 = 180

∠RWQ = 180 - 110

∠RWQ= 70°

∠PWU +  ∠USP + ∠ WPS = 180  {angle sum property of triangle}

∠PWU + 40 + 70 = 180

∠PWU + 110 = 180

∠PWU = 180 - 110  

∠PWU = 70°

Answer:

A

Step-by-step explanation:

∠WPS +∠OPW  = 180 (adj angles on a str line)

       ∠WPS +110 = 180

                ∠WPS = 180 - 110

                            = 70°

∠RWQ + ∠QWT +∠TWU = 180 (adj angles on a str line)

            ∠RWQ + 60 + 50 = 180

                   ∠RWQ + 110 = 180

                             ∠RWQ = 180 - 110

                                         = 70°

∠PWU +  ∠USP + ∠ WPS = 180 (adj angles on a str line)  

            ∠PWU + 40 + 70 = 180

                     ∠PWU + 110 = 180

                              ∠PWU = 180 - 110  

                                          = 70°

Answer:  0.0766

Step-by-step explanation:

Let x be the random team scores.

Given: Mean = 76

Standard deviation = 8.4

We assume that x follows normal distribution.

The probability that a random team scores less than 64 points = P(x<60)

[tex]=P(\frac{x-\mu}{\sigma}<\frac{64-76}{8.4})\\\\=P(z<-1.4286) \ \ \ [Z=\frac{x-\mu}{\sigma}]\\\\= 1-P(z<1.4286)\\\\=1-0.9234\\\\=0.0766[/tex]

Hence, the probability that a random team scores less than 64 points =0.0766

Answer:

5 =x

Step-by-step explanation:

The top and the bottom are the same length

17 = 3x+2

Subtract 2 from each side

17-2 = 3x+2-2

15 =3x

Divide by 3

15/3 = 3x/3

5 =x

Answer:

x = 5

Step-by-step explanation:

3x + 2 = 17

3x + 2 - 2 = 17 - 2

3x = 15

3x ÷ 3 = 15 ÷ 3

x = 5

Answer:

Answer:

120 - 4.5t= 75

t = 10 minutes

Step-by-step explanation:

the equation :

120 - 4.5t= 75

the solution:

-4.5 t = 75-120

-4.5t = -45

t = -45/(-4.5) = 10 minutes

The equation to model the given situation is 120 - 4.5t= 75 and the  solution to the equation is 10 minutes.

Given that, a hot air balloon is cruising at an altitude of 120 meters above the ground when it begins its descent.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The balloon will reach an altitude of 75 meters above the ground.

Now, 120-75 =45 meters

Let t be the time to descends 45 meters

So, 120 - 4.5t= 75

⇒ -4.5 t = 75-120

⇒ -4.5t = -45

⇒ t = -45/(-4.5)

⇒ t = 10 minutes

Hence, the equation to model the given situation is 120 - 4.5t= 75 and the  solution to the equation is 10 minutes.
