Evaluate the expression 2x2+5y2 when x=−4 and y=3.

If Jacob lives until the end of the term of his policy, the total amount he would have paid in premiums overall is $50,850.

Total premium payment = (face value / average premium rate) x number of years x premium

($500,000 / 1000) x $6.78 x 15 = $50,850

Answer: 4 yd x 3.5 yd

Step-by-step explanation:

A = LW

L = 2x - 3

W = x

14 = (2x - 3)(x)

14 = 2x^2 - 3x

2x^2 - 3x - 14 = 0

(x + 2)(2x - 7)

x = - 2, 7/2 or 3.5 (length cannot be negative)

x = 3.5 (width)

Length

2x - 3

2(3.5) - 3

7 - 3 = 4

The angle which is coterminal with the angle 125 degree when drawn in standard position is -235 degrees. Option A is correct.

The terminal side of an angle is the rotated side of the initial side around a point to form an angle. This rotation can be clockwise or counter clock wise.

The angle given in the problem is,

θ=125°

The angle which is coterminal of this angle is,

θ=125°-360°

θ=-235°

Thus, the angle which is coterminal with the angle 125 degree when drawn in standard position is -235 degrees. Option A is correct.

The function of the exponential decay will be y = 870(0.75)ˣ. Then the value of the quantity after 10 weeks will be 49.

Consider the function:

y = a(1 ± r)ˣ

where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

If there is a plus sign, then there is exponential growth happening by r fraction.

If there is a negative sign, then there is exponential decay happening by r fraction.

A quantity with an initial value of 870 decays continuously at a rate of 0.75% per day.

Then the function is given as

y = 870(0.75)ˣ

Then the value of the quantity after 10 weeks will be

y = 870(0.75)¹⁰

y = 870 (0.0563)

y = 48.99

y ≅ 49

The total distance to to his grandmothers house is assumed to be 1

Marks family traveled 7/10 of the distance to his grandmothers house on Saturday. The remaining distance would

1 - 7/10 = 3 /10

They traveled 2/3 of the remaining distance on Sunday. This means that the distance that they travelled on Sunday is

Answer:

Step-by-step explanation:

7.75-4,5 = 3.25

11-7.75 = 3.25

14.25-11 =3.25

17.5-14,25 = 3.25

It’s clear that this is an arithmetic sequence with common difference of 3.25

The equation form of such sequence is  a(n) = a×n + b ,where ‘a’ is the common difference.

Then

a = 3.25

The first term a₁ = 4.5

On the other hand, a₁ = 3.25 ×(1) + b

Then

4.5 = 3.25 ×(1) + b

Then

b = 4.5 - 3.25 = 1.25

Conclusion:

a(n) = 3.25n + 1.25

Step-by-step explanation:

On a standard graph, the horizontal line is the x-axis and thr vertical is the y-axis

[tex] \sin {}^{2} (x) + {cos}^{2} (x) = 1[/tex]

[tex] {sin}^{2} (x) = 1 - {cos}^{2} (x)[/tex]

[tex] {sin}^{2} (x) = 1 - ({ \frac{ - 7}{9} })^{2} \\ [/tex]

[tex] {sin}^{2} (x) = 1 - \frac{49}{81} \\ [/tex]

[tex] {sin}^{2} (x) = \frac{81}{81} - \frac{49}{81} \\ [/tex]

[tex] {sin}^{2} (x) = \frac{32}{81} \\ [/tex]

[tex] \sin(x) = ± \sqrt{ \frac{32}{81} } \\ [/tex]

_____________________________________________

[tex] \tan(x) < 0 \: \: \: and \: \cos(x) < 0[/tex]

Thus :

[tex] \sin(x) > 0[/tex]

So we have :

[tex] \sin(x) = + \sqrt{ \frac{32}{81} } \\ [/tex]

[tex] \sin(x) = \frac{ \sqrt{16 \times 2} }{ \sqrt{9 \times 9} } \\ [/tex]

[tex] \sin(x) = \frac{4 \sqrt{2} }{9} \\ [/tex]

_____________________________________________

[tex] \sin(2x) = 2 \times \sin(x) \times \cos(x) [/tex]

[tex] \sin(2x) = 2 \times \frac{4 \sqrt{2} }{9} \times ( - \frac{7}{9} ) \\ [/tex]

Answer:

  -1/2x -(5 23/42)y

Step-by-step explanation:

We assume you want to simplify the expression ...

  (2 3/10)x -(5/7)y -(4 5/6)y -(2 4/5)x

__

The mixed numbers and fractions are combined in the usual way. A common denominator needs to be found for the addition or subtraction to take place.

  = x(2 3/10 -2 4/5) -y(5/7 +4 5/6)

  = x(23/10 -28/10) -y(30/42 +4 35/42)

  = x(-5/10) -y(4 65/42)

  = -1/2x -(5 23/42)y

Answer:

1/100

Step-by-step explanation:

From 1 to 10 there are 10 numbers, so the fraction would be:

# / 10

Since you are putting the cards back into the deck, the denominator will never change.

The chances of getting " 1 " are 1 / 10.

And the chances of getting " 2 " are also 1 / 10

To find the odds of getting one-after-the-other, you multiply these 2 chances.

( 1 / 10 ) x ( 1 / 10 ) = ( 1 / 100 )

There is a 1 / 100 chance that you will draw 1, then 2 if you put the cards back after drawing.

The exact value of the other root to the quadratic equation is [tex]x = -2 - \sqrt 6[/tex]

One of the root is given as:

[tex]x = -2 - \sqrt 6[/tex]

As a general rule, the solution to a quadratic equation is represented by:

[tex]x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]

This means that the actual root of the given root is:

[tex]x = -2 \pm \sqrt 6[/tex]

Split the equation

[tex]x = -2 - \sqrt 6[/tex] and [tex]x = -2 + \sqrt 6[/tex]

Hence, the exact value of the other root to the quadratic equation is [tex]x = -2 - \sqrt 6[/tex]
