Answer:

A: (3/5, 0)

Step-by-step explanation:

y = 3 - 5x

-5x = y - 3

x = -y/5 + 3/5

An exponential function with a horizontal asymptote at y = -2 will be of the form:

f(x) = 2^(-x) - 2

An exponential equation will have a horizontal asymptote when the exponent, x, has a negative sign. This will cause that as x tends to infinity, the exponential part of the function will tend asymptotically to zero.

Now, if we want to have an horizontal asymptote at y = -2, then we also need to have a constant term equal to -2 which takes weight as x tends to infinity, and the other part of the function becomes almost zero.

So the function will be something like:

f(x) = 2^(-x) - 2

Answer:

the interest that have to paid is $9,676.91

Step-by-step explanation:

The computation of the interest to be paid is as follows:

= Future value - initial value

= $10,200 × (1 + 0.21)^3.5 - $10,200

= $19,876.91 - $10,200

= $9,676.91

Hence, the interest that have to paid is $9,676.91

We simply applied the above formula so that the correct value could come

Answer:

Approximately what will be saved will be 8.00

Step-by-step explanation:

Here, we want to know the amount that the customer will save

Firstly, we need to know the amount that all will cost

Mathematically, that will be;

24 + 16.12 + 10.5 = 50.62

The amount to be discounted is 15% of this

That will be 15% of 50.62

= 15/100 * 50.62

= 7.593

Answer:

[tex]2\times 15-6 = 24\ below\ sea\ level[/tex]

Step-by-step explanation:

Given that:

Distance traveled by seal to catch the fish = 15 below sea level

Sea lion wanted to catch a larger fish so sea lion dove 6 feet lesser than two time the distance that the seal traveled.

To find:

The expression to represent the position of the sea lion in the sea.

Solution:

If the distance traveled by seal is represented by [tex]D[/tex] then as per the question statement:

Twice of [tex]D[/tex] = [tex]2\times D[/tex]

6 lesser than twice of [tex]D[/tex] = [tex]2\times D[/tex] - 6

Now, putting the value of [tex]D[/tex] = 15

Therefore, the expression to represent the sea lion's position w.r.to sea level.

[tex]2\times 15-6\\ = 24\ below\ sea\ level[/tex]

Answer:

width = 15 inches

length = 30 inches

Step-by-step explanation:

[tex]\sf \boxed{\text{\bf Perimeter of rectangle =2*length + 2*width}}[/tex]

  Let width = x inches

     Length =  2*x = 2x inches

                 Perimeter = 90 inches

2 *length  + 2* width = 90

            2*2x  + 2*x     = 90

                   4x + 2x    = 90

Combine like terms,

                             6x = 90

Divide both sides by 6,

                                x = 90/6

                                x = 15

Dimensions:

Width = 15 inches

Length = 2*15 = 30 inches.

After evaluating the limit we get the answer as 3/5.

Given the expression is : limₓ₋₋₎₀ cos 2x ₋ cos 4x/1-cos2xcos4x

= limₓ₋₋₎₀  cos2x - (2cos²2x ₋ 1)/1-cos2x(2cos²2x - 1)

= limₓ₋₋₎₀  -2cos² + cos2x +1/₋2cos³2x + cos2x + 1

let u =cos2x that is, u → 0

= limu₋₋₎₁  -2u²+u+1/₋2u³+u+1

= limu₋₋₎₁  2u + 1/2u²+2u+1

= 2+1/2×1² + 2 × 1 +1

= 3/2+2+1

= 3/5

hence we get the value as 3/5.

Answer:

-30 feet

Step-by-step explanation:

What we know:

The rollercoaster first rose 210 feet, so after rise 1, the height is +210 feet.

After that, it dropped 240 feet. This is greater than the 210 feet it initially rose, so the number is now negative. The height is now -30 feet.

210 - 240 = -|240-210| = -|30| = -30 feet

After that, it rose another 80 feet. That outdoes the eariler -30 feet, so we're back to a positive height. After that rise, the height is now +50 feet.

-30 + 80 = |80 - 30| = |50| = 50 feet

Then the last two drops combine for a 80-foot drop. This is greater than the +50-foot height it was at, so we're back at -30 feet.

50 - 80 -|80 - 50| = -|30| = -30 feet after the last drop

Answer:

The equation [tex]x^2 + 6x -5 = 4x^2[/tex] have 2 non-real solution, 2 imaginary solutions.

Step-by-step explanation:

Using the Discriminant to find the number and type of solutions to [tex]x^2 + 6x -5 = 4x^2\\x^2-4x^2+6x-5=0\\-3x^2+6x-5=0[/tex]

The discriminant is: [tex]b^2-4ac[/tex]

We have a = -3, b=6 and c=-5

Putting values and finding discriminant

[tex]b^2-4ac\\=(6)^2-4(-3)(-5)\\=36-60\\=-24\\[/tex]

So, we get discriminant = -24

if discriminant  < 0 the solution will have two non-real imaginary solutions.

In our case discriminant  < 0 i,e discriminant  = -24

So, The equation [tex]x^2 + 6x -5 = 4x^2[/tex] have 2 non-real solution, 2 imaginary solutions.

Answer:

  A.  0.8340

Step-by-step explanation:

The mean difference between walking time and bus time is the difference of their means: 16 -12 = 4 minutes.

The variance of the difference between walking time and bus time is the sum of the variances of the two distributions:

  (4 min)² +(1 min)² = 17 min²

Then the probability that walking will be slower is the probability that the difference is greater than 0.

  P(dif > 0) = P(Z > (0 -4)/√17) = P(Z > -0.970143)

  P(dif > 0) ≈ 0.8340

The probability the bus will be faster is about 0.8340.

After putting the value of y into the eq. (ii) ,

[tex] \sf 3x + 2 \times 5x = 52[/tex]

[tex] \sf ⇒ \: 3x + 10x = 52[/tex]

[tex]⇒ \sf13x = 52[/tex]

[tex] \sf ⇒x = 4[/tex]

After putting the value of x into the eq. (1)

[tex] \sf \: y = 5 \times 4[/tex]

[tex]⇒ \sf y = 20[/tex]

Hence, the value of x is 4

& the value of y is 20.

Answer:

y = 2x², 0, 2, 8

y = 2^x, 1, 2, 4

Step-by-step explanation:

For the first equation, multiply the input by itself and then multiply by two

y = 2x²

y = 2(2)²

y = 2(2*2) = 8

For the second equation, multiply 2 by itself depending on the value of the input

y = 2^x

y = 2²

y = 2 * 2 = 4

Given:

Cecile uses [tex]\dfrac{1}{3}[/tex] of her supply of sunflower seeds to make a salted snack mix and [tex]\dfrac{2}{9}[/tex] of her supply to make an unsalted snack mix.

Cecile uses 10 pounds of sunflower seeds.

To find:

The total pounds of seeds in her supply.

Solution:

Let x be the total pounds of seeds in her supply.

Cecile uses [tex]\dfrac{1}{3}[/tex] of her supply of sunflower seeds to make a salted snack mix, i.e., [tex]\dfrac{1}{3}x[/tex].

Cecile uses [tex]\dfrac{2}{9}[/tex] of her supply to make an unsalted snack mix, i.e., [tex]\dfrac{2}{9}x[/tex].

Total sunflower seeds used = 10 pounds.

[tex]\dfrac{1}{3}x+\dfrac{2}{9}x=10[/tex]

[tex]\dfrac{3x+2x}{9}=10[/tex]

[tex]5x=10\times 9[/tex]

[tex]5x=90[/tex]

Divide both sides by 5.

[tex]x=18[/tex]

So, there are 18 pounds of seeds in her supply.

Therefore, the correct option is A.
